Electrical devices（仪器）could soon use power make 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 sown 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（起博器）. 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.The second paragraph mainly talks about .

| 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 |

Liberal Party leader Justin Trudeau stands with his wife, Sophie Gregoire, as he gives his victory speech after Canada's federal election in Montreal, Quebec, Oct. 19, 2015.
“Tonight I'd like to toast(为……干杯) the future prime minister of Canada: to Justin Pierre Trudeau."
American President Richard Nixon had that to say in 1972 at a state dinner to Canadian Prime Minister Pierre Trudeau about his newborn son, Justin. Forty-three years later, Justin Pierre Trudeau has become the second-youngest prime minister in Canada. His Liberal Party(自由党) won a majority in Monday's national election over the Conservative Party(保守党).
Justin Pierre Trudeau came from Canada's political royalty. He is the son of Pierre Trudeau and Margaret Sinclair Trudeau. His father, Pierre Trudeau, served two terms as Prime Minister between 1968 and 1984. His mother, Margaret Sinclair Trudeau, came from a well-known family of politicians. She married the 51-year-old prime minister when she was 22. Margaret Trudeau was known for her partying at New York nightclubs with stars like the Rolling Stones. The couple inspired "Trudeaumania" and was frequently compared to the American Kennedys, another political royal family.
Young Trudeau graduated from McGill University in 1994. He spent his early years as a schoolteacher in Vancouver. He is married to Sophie Grégoire, a former broadcaster. They married in 2007. They have three children.
Justin Pierre Trudeau is promising "real change" in domestic and foreign policy. He told supporters earlier Tuesday that a positive campaign led to the victory.
"This is what positive politics can do," Trudeau said. "Canadians from across this great country sent a clear message tonight."
Mr. Trudeau promises to invest(投资) in rebuilding roads and bridges. He also plans to raise taxes on wealthy Canadians.
Like his father before him, the young Trudeau has already received international attention on his election as prime minister. Major American newspapers like the New York Times and Wall Street Journal published his victory on the front pages. News websites from Le Monde of Paris to the Times of London headlined the return of "Trudeaumania" in their coverage.
How old is the new Canadian prime minister?
| A．51 | B．47 |
| C．43 | D．The text doesn’t tell us. |
Which of the following statement is WRONG?
| A．There is more than one American president coming from Kennedy family. |
| B．Justin Pierre Trudeau will continue the political view "Trudeaumania" |
| C．Justin’s positive campaign won many voters(选民). |
| D．Justin Pierre Trudeau has attracted wide attention of the Press. |
What’s the main idea of the text?
| A．Liberal Party has been the leading party in Canada. |
| B．Justin Pierre Trudeau won a victory in Canada's election |
| C．A great political royal family in Canada. |
| D．A new political star and his happy family. |
Man still has a lot to learn about the most powerful and complex part of his body — the brain.
It may be surprising to learn that it isn’t age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let’s look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order.
Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.
This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.
Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.According to the text, you lose your memory by ________.
| A．getting too old | B．hardly using your brain |
| C．working too hard | D．using your brain too much |
To fight forgetting effectively, we're advised to ________.
| A．go back to what was learned regularly |
| B．break down materials into small pieces |
| C．focus on both ends of a learning period |
| D．take breaks to give the brain a good rest |
During the learning process the brain need breaks to ________.
| A．use the right side of the brain |
| B．revise newly learnt materials |
| C．take in what has been learnt |
| D．relax the left side of the brain |
Where is this text most probably taken from?
| A．Science fictions. | B．Students’ literature. |
| C．An advertisement. | D．A science report. |

A recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlors(客厅) where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets.
This can clearly be seen when we look at pet foods, which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it is not unusual for me to get hot under collar when I read an old man left all his money to his dog instead of his children.
There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of rabies — a disease with no known cure.
Another problem is the carelessness of pet owners. Most little children want a dog or a cat, and they continually push their mothers and fathers until they get one. It is only when the "sweet little thing" has been brought home that the parents realize how much time and money must be spent on "Rover" or "Bonzo". Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone's pet and you must have read of children being hurt by some pets of their own.
Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it's time we stopped being sentimental about pets. I can see no reason why we should get upset when animals are cut up for medical experiments. This will lead us to discovering cures for serious human diseases, then I say, “keep cutting!”The doggy parlors are mentioned in the 1st paragraph to show ________.
| A．where Americans keep their pets |
| B．what costly lives the pets are living |
| C．why children love their pets so much |
| D．how much pets depend on their masters |
In the second paragraph "to get hot under the collar" probably means ________.
| A．getting quite hot | B．feeling overwhelmingly angry |
| C．becoming excited | D．receiving a fashionable shirt |
According to the author, in which field can animals be most useful?
| A．Pet. | B．Food. | C．Medicine. | D．Sports. |
What is author’s attitude towards pets-raising?
| A．Pitiful. | B．Neutral. | C．Opposed. | D．Supportive. |
My family moved from Taiwan to a small town in central Georgia, where my dad got a visa for his family and a job. I had just learned English, and from what little I could gather from my classmates, Santa Claus would come down one’s chimney and put toys in one’s stocking on Christmas Eve! What a great country, I thought. After I looked up “stocking” in my Chinese-English dictionary, I knew what I had to do.
On that fateful night, after everyone went to bed, I took my longest, cleanest knee sock and attached it to a nail already on the mantel(壁炉). Obviously, the previous owners of this house were no strangers to this Santa character.
I woke up before everyone else on Christmas Day and ran to the fireplace. To make a sob story short, I was hit with the reality of an empty sock and the biggest lie ever told. I burst into tears, quickly took down the sock, and stuffed it in the back of a drawer. Santa was dead.
Every December since then, the topic of Christmas memories would unavoidably come up, and I would amuse my friends with my poor-little-me story. I had to make it as funny as possible, or else I would cry.
How could I know that Santa was just late? Nine years ago, on Christmas Eve, an older man with a white beard and a red cap knocked on my front door. He said, “I’ve been looking for you for twenty-five years.” He handed me a bulging red stocking, winked, and left. On top of the stocking was a card. It read: “For Becky—I may have missed you in the second grade, but you’ve always lived in my heart. Santa.”
Through tear-blurred eyes, I recognized the handwriting of Jill, a friend I had met just two months before. I later discovered that the older man was her father. Jill had seen the hurt little girl underneath the thirty-something woman and decided to do something about it.
So now I believe that Santa is real. I don’t mean the twinkle-eyed character of children’s mythology or the creation of American holiday marketers. Those Santas annoy and sadden me. I believe in the Santa Claus that live inside good and thoughtful people. This Santa does not return to the North Pole after a crazy delivery but lives each day purposefully, really listens to friends, and then plans deliberate acts of kindness.What does the underlined part “what I had to do” in Paragraph 1 refer to?
| A．Waiting for Santa Claus. |
| B．Putting a stocking on the mantel. |
| C．Asking for gifts from her parents. |
