<passage>:
It was just three degrees above zero. "That's cold," thought Jane as she got ready to deliver her morning papers. Jane has 50 customers, and on cold mornings when she couldn't ride her bike, it took her more than an hour to make her rounds.
As she collected her papers and put them into a big canvas bag, Jane regretted that she hadn't finished her math homework the night before. There was still time. She'd hurry with the papers and finish the math before breakfast.
Less than an hour later, Jane was nearly finished. She had only five customers to go. She could then head for home to complete her math while her mom fixed breakfast. As she rounded the corner, she saw a car in the middle of the street. It was Mr. Zimmerman, the elderly man who walked with a walking stick. His car was out of gas.
"I'd like to help Mr. Zimmerman," thought Jane. "but if I do, I won't have time to do my homework." She hated to think what Mr. Roberts would say if she hadn't completed her papers.
"It's his own fault for running out of gas," Jane talked to herself, "the station is only a half mile down the street. Surely Mr. Zimmerman can walk that far, even on a cold morning like this... can't he?" As she walked down the street, Jane wondered what to do.

<question>:
The reading doesn't say but we can infer that  _

<options>:
A Jane bought the gas for Mr. Zimmerman
B usually Jane delivers papers by bike
C Mr. Robert doesn't like Jane at school
D Mr. Zimmerman had to leave the car for Jane

<passage>:
From the same place that brought you the Robot Suit HAL comes the "motorized knee".Designed by researchers at Japan's Tsukuba University, the device supports the flex( ) of the knee, which enables a runner to use 30% less muscle power compared to running unassisted.
Coming in a kit  , the device consists of a small motor that helps flex the knee, a sensor that detects the knees' degree of flex, and a safety lever  --all of which attach to the user's leg.The user is also forced to carry a backpack that holds a control unit and battery to power the motor.All up the device weighs around 5kg,which will probably lessen the performance benefits of wearing the device somewhat.In experiments runners wearing the device could jog at 7.5kmh, which is hardly anything special--but predictably they could do it for longer.
Curiously, the makers of the motorized knee say it isn't designed for the physically handicapped.Rather it is intended for people who want to run in a more efficient way.I can't help thinking this cuts down the potential market considerably.After all, most runners I know do it for the sake of their fitness.Wouldn't a device that is designed to do some of the work mean that someone would have to run for longer to receive the same fitness benefits?
Regardless, the research team expects to commercialize the kit within the next three years, by which time they also plan to have made the device significantly smaller and lighter.

<question>:
To make sure that the device runs smoothly,  _  .

<options>:
A the user should be equipped with other related units
B the device should be improved through experiments
C the user shouldn't be physically handicapped
D the device should be smaller and lighter

Read the following passage and questions, then choose the right answer from options, the answer should be one of A, B, C, D.

<passage>:
The vast jungles of the Amazon rainforest are home to tribes mostly isolated from the outside world,whose way of life,largely unchanged for hundreds of years,is now increasingly threatened by modern civilization.
Now, scientists discover they can monitor these"uncontacted tribes"using satellites,which would allow inexpensive and safe tracking of these tribes in order to protect them from outside threats.
In order to help conserve these uncontacted Indians,researchers need accurate estimates of their populations.One way to collect this data involves flying over their villages,but such overflights are both expensive and could fill these native peoples with fear.Another strategy involves meeting individuals on the ground,but among other risks,scientists could accidentally spread disease to members of the tribes.
Instead,scientists investigated whether satellite imaging could monitor uncontacted tribes. The result was inspiring.They confirmed their locations and measured the sizes of their Village,houses and gardens."We can find isolated vinages with remote sensing and study them over time."Walker told Live Science."We can ask:Are they growing?Do they move?"
Surprisingly,based on the sizes of the houses and Villages,the scientists find the population densities of these isolated villages are about 10 times greater,on average,than other villages of native Brazilian peoples.This may be due to the fact that they have to live closer together because they are not as good at clearing the forest,since they lack modern devices like chainsaws and tractors,the researchers said.The tribes may also be afraid of spreading out due to fear of being attacked by outsiders,Walker said.
The researchers now plan to focus on 29 more isolated villages to"look at their ecology--that is.distance from rivers and roads--and use this to model where else we can find more isolated villages,"Walker said.

<question>:

<passage>:
It was time for a school holiday and I was at home. My family's house was located in   an area by the sea.
I just sat down in front of the television. Suddenly I heard a loud noise and then the first shock started to hit. My mom and I ran to the front door. We got out and we were standing in the street holding on to each other to stand up. The ground was covered with snow. I could remember watching black cracks in the earth snaking their way along the ground. A tree in our back yard was actually cut in half.
As suddenly as the earthquake started, it was over. Dead silence. Then a light snow began to fall. All the power was off--no radio, no TV and no communication with the outside world. We found out later that the ground area was lowered an average of 35 feet.
My dad succeeded in getting home from where he worked in the city centre. Later that evening we were told to leave the area because a terrible ocean wave was expected. We spent the night and the next day and night away from home at the shelter.
I often think about the courage my dad showed during that time. Before Dad retired, he was a senior manager of a famous local company. This company was damaged because of the quake. Dad stayed in the company to rebuild the business and rebuild our family home.

<question>:
In which season did the earthquake take place?

A Spring.

C Autumn.
D Winter.

<passage>:
With more and more wineries   offering organic varieties to lower their eco-footprint  , it's no surprise that they're looking at the environmental impacts of their packaging as well. The making of conventional glass bottles and the corks   uses large quantities of natural resources and causes a lot of pollution.
Beyond manufacturing, the transport of wine in glass bottles across the country and around the world also has its environmental effect. Trucking all the heavy glass bottles causes a much larger carbon footprint than the transportation of much lighter boxed wine. Almost half the weight of an ordinary case of wine comes from the bottles; about 95 percent of the weight of a case of boxed wine is the wine itself.
"A standard wine bottle holds 750 milliliters of wine and causes about 5.2 pounds of carbon dioxide when it travels from a farm in California to a store in New York," reports Colman, a researcher. "A 3-liter box causes about half the carbon dioxide per 750 milliliters."
According to the Wine Group, the third largest wine company in the world and a big advocate for switching away from glass bottles, there are other advantages to boxed wine (which typically includes a plastic bag within a cardboard box). The vacuum   packaging of boxed wine allows it to stay fresh for up to six weeks in the fridge once the seal is broken and the first glass has been poured.
Still, despite the benefits, boxed wine may still be a tough pill to swallow for many wine experts. "Even those traditionalists who are coming around to the idea that maybe screw caps   are fine for some wines, would not like the idea of a cellar   full of cardboard boxes," says wine writer Lee Asbell. "It is difficult to imagine how wine service at fine-dining establishments would handle such a change." For now, boxed wine is still the field of cheaper brands. But that could all change as more and more wine makers and drinkers take responsibility for saving the Earth.

The Internet has become a part of our everyday life and there is nothing we can do without it.It is a means of communication as well as a good way of relieving and having fun.No matter in what place of the world,the Internet is the same for every one of us.
    If we hope to improve our knowledge or look for a certain piece of information, the Internet is the perfect tool for our need.If we do not have the time to shop, ordering online is the solution to our problem.The Internet is very useful to most  people.
    There is no doubt that the Internet also has some bad points.I'm speaking about the harmful information,which may come up in the most unexpected paces.You can sometimes come across violence,presented to the public as a very normal way of expressing beliefs.An intelligent person will always be able to tell apart right and wrong, but what can we do to help the teenagers and children? This sort of information is a cause of many of the violent incidents in schools.
    There are few organization that monitor the Internet and the information on it.They cannot possibly get rid of all the bad things on the Internet.
    So should the Internet be censored for the protection of children? My belief is that parents are the ones who should be to blame for what their children ale doing on the Internet.

    There are few organization that monitor the Internet and the information on it.They cannot possibly get rid of all the bad things on the Internet.
    So should the Internet be censored for the protection of children? My belief is that parents are the ones who should be to blame for what their children ale doing on the Internet.

<passage>:
Five-year-old Jocelyn Rojas spent all day playing happily with her friends outside her grandmother's apartment building. Her mom, Jaimee, kept her eye on the little girl from a window. At about 4 p.m., Jocelyn walked around the corner of the building to get her bicycle. However, half an hour later, she disappeared. Jaimee called 911.
A short time later, police officers and firefighters crowded inthe area, blocking streets and searching the neighborhood. Officers handed out photos of the girl wearing thick-framed glasses.
Temar Boggs, 15, a school athlete in track, was with some friends moving a couch into the apartment of his elderly neighbor when one officer approached him and asked if he'd seen Jocelyn. Unfortunately, none of them had seen her. A little bit later, Temar and his friends went to check out the situation. By 6:30 p.m., Jocelyn had been missing for more than two hours, and the search team was worried that the sun would set before she was found.
Just at that moment, Temar felt an intense emotion that he was going to find her. He and his friend Chris Garcia, 13, rode alongside, simply keeping a sharp eye out as they circled around. Then Temar spotted a car circling around, as if the driver were unfamiliar with the neighborhood. Temar cycled close and made eye contact with the man behind the wheel, an older guy wearing a red-and-white striped shirt, and saw a tiny blond girl in the passenger seat. Temar instantly realized it must be the missing girl.
The boys cycled after the car, but the driver kept moving, winding his way through the neighborhood.
Finally, the driver had to park the car ahead of them and pushed open the passenger-side door. A girl slipped out of the car. It was Jocelyn. Temar got off his bike, and carried her to the police. The kidnapper sped away.
A police report later identified the man as a 63-ycar-old sex offender. He is still _ .
Neil Harkins, chief of the Manheim Police Department, says "The boys' heroics are 'something we don't normally hear about.' It is a very brave thing for young boys to do that." But when asked, Temar, now a tenth-grade student at Lucy Laney High School, says "I didn't do it for attention. I just wanted to help."

<question>:
Why did Jaimee call 911?

<options>:
A Because her mother was in need of help.
B Because her house was on fire.
C Because her daughter was missing.
D Because she was trapped in the building.

High Speed Book Scanner
Simply turning pages of a book quickly may not seem like the best way to scan it. A Japanese research group at Tokyo University has created new software that allows hundreds of pages to be scanned within minutes. Scanning text is normally a boring process with each page having to be inserted into a scanner, but the team led by Professor Masatoshi Ishikawa uses a high speed camera that takes 500 pictures a second to scan pages as they are turned by workers.
Normal scanners can only scan the information that is actually before them on the page. This high speed book scanner uses a camera that captures pages at 1000fps as they are turned. A system built in allows it to automatically correct any changes to the text due to the page bending as well as light differences due to shadows. "It takes a shot of the shape, then it calculates the shape and uses those calculations to film the scanning," Ishikawa said, explaining the system used to reconstruct the original page.
The current system is able to scan an average 250-page book in a little over 60 seconds using basic computer hardware. While it now requires extra time to process the scanned images  , the researchers hope to eventually make the technology both faster and much smaller. "In the more distant future, once it becomes possible to put all of this processing on one chip   and then put that in an iPad or iPod, one could scan just using that chip. At that point, it becomes possible to scan something quickly to save for later reading," Ishikawa said.
Being able to scan books with an iPhone may be further off, but Ishikawa says that a commercial version of the large-scale computer based scanning system could be available in two or three years. While the technology has the potential to take paper books into the digital age,

<passage>:
The United States government has decided that food from cloned  cattle, pigs and goats is safe to eat. The Food and Drug Administration also says it found no risks in meat and milk from cloned animals.
The F.D.A. looked at studies for several years before it announced its decision in a final report this month. The United States Department of Agriculture supported the findings. But it says time is needed to clear the way for marketing meat and milk from clones.
The F.D.A. will not require any product to be registered  as coming from clones. A producer would need to label   a product "clone-free". The agency   says that could be misunderstood because the food is not different from other food.
But activists argue that the F.D.A. based its decision on incomplete research into possible risks. The Center for Food Safety criticized the use of studies supplied by cloning companies. Animal rights activists point out that cloning attempts often fail. They say cloning is cruel and can lead to suffering.
Congress   has been trying to get the F.D.A. to do more studies. But the agency noted that experts in New Zealand and the European Union had come to the same findings about the safety of food from clones. Japan, South Korea and Taiwan say they want to study it further before taking action.
Products from cloning may not be widely used for several years. Clones cost much , which is why they are not widely used for feeding. The Agriculture Department says few clones will ever become food. Their traditionally raised animals would enter the food supply instead.

<question>:

<passage>:
Monkeys are very similar to us in many ways. We enjoy watching them because they often act like us. In fact, scientists say monkeys and humans share a common ancestor.
Monkeys make us smile, too, because they are creatures full of playful tricks. This is why many monkey expressions are about tricky people or playful acts. One of these expressions is monkeyshines, meaning tricks or foolish acts. So, when a teacher says to a group of students: "Stop those monkeyshines right now!", you know that the kids are playing, instead of studying.
You might hear that same teacher warn a student not to monkey around with a valuable piece of equipment. You monkey around with something when you are touching or playing with something you should leave alone. Also, you can monkey around when you feel like doing something, but have no firm idea of what to do.
 Monkey business usually means secret, maybe illegal, activities. A news report may say there is monkey business involved in building the new airport, with some officials getting secret payments from builders.
You may make a monkey out of someone when you make that person look foolish. Some people make a monkey out of themselves by acting foolish or silly.
If one monkey has fun, imagine how much fun a barrel of monkeys can have. If your friend says he had more fun than a barrel of monkeys at your party, you know that he had a really good time.
Monkey suits are common names for clothes or uniforms soldiers wear. In earlier years, performing monkeys' tight-fitting, color1ful jacket looked similar to a military uniform. So, people began to call a military uniform a monkey suit.

<question>:

<passage>:
I am sure that everybody in his/her life has used computers. Nowadays you can feel their presence everywhere at home,at school,at work and they certainly make life easier.On the other hand,there are people who can't work with them.
Anyway,I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal,to withdraw your money, and also save your time,because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them;the whole planet seems to be one big computer society.
Nevertheless,problems can often appear in this area, too.To have a computer means you have to be quite well-off and have the necessary skills to use it.However,think about questions like "Are computers so available for everyone, or rich and poor people,for people from villages and people from cities. Aren't they too expensive?Is everyone able to learn how to use them and not everyone has the chance to access and work with them,how could everything in the future be dependent on them?"Therefore,I think our society will be split into two parts.One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group.
Another question that bothers me is,on the one hand,computers are important  and good things in our life,but they aren't everything.They are good as a help at school,quite often as entertainment,especially for young people,as an necessary tool to help in research etc,but I think we shouldn't be so dependent on them,because computers are only machines and machines can't feel anything be human and sympathetic,and every action performed by computer can be interfered with another person,which could cause these machines to crash or work badly.
In conclusion,I would like to say I am not against computers.I use computers,too,but people should be wary all the time.

<question>:
The writer's main purpose in writing the passage is  _

<options>:
A to encourage us to use computers in our society
B to advise us to say no to computers from now on
C to remind us to care about the problems that computers bring.
D to inform us that the computer has become a necessary part of our life

Hair has always been an important sign of beauty, especially true for women.Next to the face, hair is one of the main qualities people look for when they consider a woman's beauty.Whether long or short, curly or straight, hair often gets a lot of attention.
Each hair grows independently of other hairs.Not all hairs experience the same period of growth at the same time.During the period of active growth, which is called Anagen, hair grows at a rate of about or one centimeter a month.About eighty five percent of hair follicles  are going through this process at any given time.This period can last from two to six years.
The Catagen period of hair growth comes next.It is then that hair growth begins to slow down.This period usually lasts two or three weeks.Finally, hair growth comes to a complete stop and the hairs begin to fall out.This period is known as Telogen.Once the Telogen period has ended, the hair growth process begins again.
So what happens when a person has trouble growing hair or suffers from hair loss? Your genes control how fast or how long your hair will grow.Some people have a longer than usual anagen growth period.These people may be able to grow more hair than the average person.
However, others struggle to grow shoulder length hair.These people have a shorter than normal anagen period.

Read the following passage and questions, then choose the right answer from options, the answer should be one of A, B, C, D.

<passage>:
Hair has always been an important sign of beauty, especially true for women.Next to the face, hair is one of the main qualities people look for when they consider a woman's beauty.Whether long or short, curly or straight, hair often gets a lot of attention.
Each hair grows independently of other hairs.Not all hairs experience the same period of growth at the same time.During the period of active growth, which is called Anagen, hair grows at a rate of about or one centimeter a month.About eighty five percent of hair follicles  are going through this process at any given time.This period can last from two to six years.
The Catagen period of hair growth comes next.It is then that hair growth begins to slow down.This period usually lasts two or three weeks.Finally, hair growth comes to a complete stop and the hairs begin to fall out.This period is known as Telogen.Once the Telogen period has ended, the hair growth process begins again.
So what happens when a person has trouble growing hair or suffers from hair loss? Your genes control how fast or how long your hair will grow.Some people have a longer than usual anagen growth period.These people may be able to grow more hair than the average person.
However, others struggle to grow shoulder length hair.These people have a shorter than normal anagen period.
Your health can also affect hair growth.Poor nutrition can cause some hair follicles to stop growing or cause the hairs that grow to become weak or thin.Problems with hair growth can result from thyroid (^?K JSO problems or other conditions.Health experts say people who experience a sudden increase in hair loss should seek medical advice.

<passage>:
The percentage of districts that require elementary schools to teach physical education increased, to 93% last year from 83% in 2000.
    But just 4% of elementary schools, 8% of middle schools and 2% of high schools provided physical education each school day, as is recommended by the disease control agency. One-fifth of schools did not require physical education at all.
    In 2004, Congress passed a law requiring each school district to develop a "wellness policy" to promote the students' health by setting goals for nutrition education and physical activity. Those policies are just now taking effect, and some school administrators predict that the next survey will show more marked improvements. Some schools have set out to place health education on the same requirement with academics. In Los Angeles County, Sepulveda Middle School has banned soft drinks and eliminated unhealthy snacks from the school store. Salad, fruit and yogurt are always available in the cafeteria, said Patricia J. Pelletier, the principal.
    Nearly an hour of physical education is required daily, the school offers after-hours training in distance running, and it has started a class on healthy cooking for parents.
    "If kids are healthy and have healthy lifestyles, they're going to be better students," Ms Pelletier said. "They're going to be in school, and they're going to be connected with the teachers in a better way."
    The survey found that nearly two-thirds of schools prohibited tobacco use at all places, including at off-campus functions, up from 46% in 2000. Another finding was that the proportion of states that require middle schools to teach human sexuality grew, to 59% from 46%.
    The report found a variety of indications of healthier cooking in school cafeterias. 55% reported that they had removed the skin from poultry before cooking, up from 40%, and 46% now use low-fat cheeses, up from 31%. But 12% of elementary schools, 19% of middle schools and 24% of high schools offer students brand-name fast food from businesses like Pizza Hut and Taco Bell.

<question>:
What is the best title for this passage?

<options>:
A How to change children's eating habits
B Improve students' physical health by developing their nutrition education
C Only a little percentage of students are taught physical education
D Healthy habits should be taught in schools

Expressions about water are almost as common as water itself.
The expressionto be in hot water is a very old expression. Hot water was used five hundred years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle.
That no longer happens. But we still get in hot water. When we are in hot water, we are in trouble. It can be any kind of trouble--serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother, if he walks in the house with dirty shoes.
Beingin deep wateris almost the same as being in hot water. When you are in deep water, you are in a difficult position.
To keep your head above wateris a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job.
Water over the dam is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again.
Another common expression to hold water, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container.; If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes.
Throwing cold water also is an expression that deals with ideas or suggestions. It means to not like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea, because she says a new car costs too much.

<question>:
