Electrical devices (儀器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

The device connects to a person's knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers (起搏器). It could even be used to assist in the movement of robotic arms and legs.

The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.

The developers hope the device will one day help developing countries. Nearly twenty-five percent of people around the world live without electric power.

A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person's back that also produces power from walking. The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

1.The second paragraph mainly talks about ________.

A. who developed the device

B. how the device works

C. several possible uses for the devices

D. how much electricity the device can produce

2.What is the disadvantage of the experimental version of the device?

A. It is too heavy for the walker to bear.

B. It is too complex for people to use.

C. It will slow down one's walking speed.

D. It is too expensive for most people to afford.

3.Compared with the device designed by Larry Rome, this new device ________.

A. produces power without adding more loads to the walker

B. can produce more power in a much shorter time

C. needs to be equipped with a battery

D. can help the walker walk faster

4.From the passage, we can learn that the electrical device can ________.

A. help housewives operate the micro-wave oven

B. make it much easier for us to go online

C. produce more electricity than that invented by Larry Rome

D. be applied in medicine to operate heart pacemakers

Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released (發(fā)布) five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.

Key 1: Keep clean

1. . People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.

Key 2: Separate raw (生的) and cooked

Raw foods should not touch prepared foods. 2. .

Key 3: 3.

People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

Key 4: Keep food at safe temperatures

When people are finished with eating, they should keep the left food in a refrigerator below 5℃ and shouldn’t store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms. 4. .

Key 5: Use safe water and raw materials

5. . Damaged or old food may develop harmful chemicals as it gets older.

A. Eat healthily

B. Cook completely

C. They can live where we make food

D. This key tells about the importance of washing

E. People should use safe water and choose fresh foods

Tom goes everywhere with Catherine Green, a 54-year-old secretary. He moves around her office at work and goes shopping with her. "Most people don't seem to mind Tom," says Catherine, who thinks he is wonderful. "He's my fourth child," she says. She may think of him and treat him that way as her son. He moves around buying his food, paying his health bills and his taxes, but in fact Tom is a dog.

Catherine and Tom live in Sweden, a country where everyone is expected to lead an orderly life according to rules laid down by the government, which also provides a high level of care for its people. This level of care costs money.

People in Sweden pay taxes on everything, so aren't surprised to find that owning a dog means more taxes. Some people are paying as much as 500 Swedish kronor in taxes a year for the right to keep their dog, which is spent by the government on dog hospitals and sometimes medical treatment for a dog that falls ill. However, most such treatment is expensive, so owners often decide to offer health and even life premium for their dog.

In Sweden dog owners must pay for any damage their dog does. A Swedish Kennel Club official explains what this means: if your dog runs out on the road and gets hit by a passing car, you, as the owner, have to pay for any damage done to the car, even if your dog has been killed in the accident.

Parents will do anything for their children. Whether it would be the food, clothes, or the place they live in, parents will always make sure their children have the best of everything. One of the biggest concerns that parents currently have is educating their children. They are faced with lots of difficulties when it comes to education for their young ones. Choices include private school, charter school, public school or home schooling.

Fortunately for parents，there are a variety of different strategies that they can take in order to increase their child’s overall intelligence. According to Ross A. Thompson, PhD, professor of psychology at the University of California at Davis, a child’s brain will actually reach 90% of its full size by the time they start kindergarten.

Researchers at Northwestern University in Chicago concluded that playing a musical instrument directly affected the brain stem, the lower section of the brain. Moreover, children that learn an instrument at an early age tend to continue it when they are older. And numerous studies show that a well balanced meal is essential for a child’s mental as well as physical health. Some other researchers recommended that a second language should be taught when children are in preschool. They state that three to four years of age is the perfect time and that any age under four would work perfectly well for a child’s brain development.

The average child will learn how to read between kindergarten and second grade. Many parents can give their children a jump start by teaching them to read before they start school. Children could have an adequate background of the alphabet and sounds of words before attending school. This can be done by simply reading to them whenever you want. The more comfortable they get, the easier the process will be.

1.From the first paragraph, we can infer that ________.

A. parents find it hard to satisfy their kids’ various demands

B. parents meet a new challenge when raising their kids

C. parents have more choices in offering education to their kids

D. parents get actively involved in the process of their kids’ growth

2.What suggestion may the researchers in the passage make?

A. To train kids as early as possible.

B. To try as many means as possible.

C. To help kids develop as fully as possible.

D. To use as many available resources as possible.

3.What is the third paragraph mainly about?

A. The proper time to teach children to learn languages.

B. The effective ways to help develop children’s brains.

C. The vital factors to have a great effect on children’s health.

D. The practical steps to arouse children’s interest in study.

4.We can replace the words “jump start” in the last paragraph with ________.

A. inspirationB. introductionC. suggestionD. promotion

When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laughs turned into crying.

So it came as no surprise to learn that researchers believe crying and laughing are controlled by the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so does crying.

Whatever helps us to reduce pressure is important to our emotional health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.

Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendlier and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.

Just as crying can be healthy, not crying—holding back tears of anger, pain or suffering—can be bad for physical health. Studies have shown that too much control of emotions can 1ead to high blood pressure, heart problems and some other illness. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural, healthy and emotional response.

1.Why didn't the author cry when her grandmother died?

A. Because her father did not want her to feel too sad.

B. Because she did not love her grandmother.

C. Because she was too shy to cry at that time.

D. The author doesn't give the explanation.

2.It can be inferred from the text that ________.

A. there are two ways to keep healthy

B. emotional health has a close relationship to physical health

C. crying has many health disadvantages

D. crying does more good to health than laughing

3.According to the author, which of the following statements is true?

A. Crying is the best way to get help from others.

B. Fighting back tears may cause some health problems.

C. We will never know our deep feelings unless we cry.

D. We must cry if we want to reduce pressure

4.What might be the most suitable title for the text?

A. Why We CryB. How to Keep Healthy

C. Power of TearsD. New Scientific Discovery

As early as the mid-18th century, some people began raising doubts about Marco Polo’s travels. In 1995, historian Frances Wood argued in her book Did Marco Polo Go to China? that the famous explorer from Venice never made it to pass the Black Sea. She noted that his travel journal left out the Great Wall of China, chopsticks and tea drinking among other details. Furthermore, Chinese documents from Polo’s day made no mention of the explorer and his men.

Wood and other scholars have argued that Marco Polo based his tales of China on information collected from fellow trades who had actually been there. Last year, a team of Italian researchers became the latest to challenge Polo’s accounts(敘述). They said that evidence didn’t support his description of Kublai Khan’s Japanese invasions (侵略）.

Now, however, research by Hans Ulrich Vogel of Germany’s Tubingen University might help prove Marco Polo was true. In a new book Marco Polo Was in China，the professor of Chinese history tries to prove that Marco Polo spoke the truth. He suggests, for example, that Polo didn’t include the Great Wall in his book because it only achieved its great importance in the Ming Dynasty several hundred years later. Vogel further explains that Chinese records from the 13th and 14th centuries avoided setting down visits from Westerners.

Historians before him have touched on these issues. But Vogel also relies on another evidence:the explorer’s very detailed descriptions of currency and salt production in the Yuan Dynasty. According to Vogel, Polo documented these aspects of Mongol Chinese culture in greater detail than any other of his time. This is a hint (暗示) that Polo relied on his own powers of observation.

Will we ever know whether Marco Polo traveled to China? Perhaps not, but the consequences of his real or fictional journey are still felt across the globe. One reader of The Travels of Marco Polo was Christopher Columbus, who stepped upon the New World while following his idol’s footsteps.

1.France Wood doubted Marco Polo’s travel’s to China because his description ________.

A. missed some important culture of China

B. covered so much about traders’ life

C. was full of obvious mistakes

D. seemed less detailed

2.Vogel’s trust on Marco Polo is based on the argument that ________.

a. The Great Wall didn’t gain its importance then

b. Records in the Yuan Dynasty mentioned Polo

c. Polo mentioned the currency and salt

d. Polo’s other works are believable

e. Polo recorded what he saw in great detail

A. a, b, dB. a, c, dC. a, eD. b, c

3.Which of the following shows the structure of the text?（P1為第一段，以此類推）
