Electrical devices(仪器) 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 shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y 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 wa1king.
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．who developed the device |
| B．how the device works |
| C．several possible uses for the devices |
| D．how much electricity the device can produce |
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 wa1k faster |
From the passage, we can learn that the electrical device can .
| A．help housewives operate the washing machine |
| 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 |
What would be the best title for the passage?
| A．First device powered by walking wi1l soon be on the market |
| B．Advanced technology brings in a new way to operate heart pacemakers |
| C．Device gives new meaning to the idea of power walking |

My grandmother was from a town in Michigan. Summer after summer, I enjoyed staying with my grandparents as a young child. I was from the city and loved the small town they lived in. People knew everyone, their kids, their pets, their ancestors. The bond with them continued to grow as I grew and they got older. Grandma was always using her hands for something exciting. She would make little sandwiches and we’d have tea parties. She’d make beautiful quilts for each one. I remember the small thimble(顶针) she would use while doing her needle work.
A few years ago, when Grandma left this earth, I bid farewell to a loving grandmother. How quickly our lives can change. We had just had tea together a couple of months earlier, on her 91st birthday.
I missed her very much. On one particular birthday, when I was feeling a little low, something happened to make me feel like she was sharing that special day with me. I was arranging some colorful pillows that she had made, and suddenly I felt something inside one pillow. It was small and hard. I moved the object to a seam(接缝) that I carefully opened, and to my delight out came a tiny silver thimble! How happy I was to find something that had been a part of her. Not realizing it had fallen off her finger, I pictured her sewing it in that little pillow that I just happened to place on my bedspead that day. I carefully laid the thimble alongside the others I’ve collected over the years, where I could continue to see the gift God chose to reveal to me. What a precious memory of a very special lady who somehow, I knew, was laughing in delight at sewing her thimble inside my pillow.
I made some tea, using my best china, as Grandma always did, and enjoyed my tea and Grandma’s thimble. What a wonderful birthday that was!

第三部分：阅读理解(共两节，满分40分)
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
The best diet for you is the one that you can follow for the rest of your life. Most diets can get you to your goal if you do exactly what they say.
The first thing to do is to look at what you’re doing now. If it’s easier for you to see where you’re going wrong by writing down what you eat for the next week, then do that.
When you become familiar with the foods you choose to eat every day, it’s easy to start to subsitute(用…代替)healthier alternatives and make better choices. Let’s take a look at some common lifestyle choices that could help you lose weight easily.
Got a soda habit?
Drink a lot of soda or fruit juices? Substitute water and tea instead. Studies show that just this one substitution can help you drop 20 pounds in a year.
Spending a lot of time buying food at the drivethrough fast food joint?
Avoid anything that you can get through a drivethrough window. Bring your lunch instead. Home cooking almost automatically guarantees a meal that’s lower in fat and calories than anything you could get through a window.
Never finish a meal without grease(油脂) on your hands?
Deep-fried foods are loaded with calories and fat. Fry in a little olive oil, instead.
Always having a lot of sauces?
Holding the mayo(蛋黄酱)or anything else that’s creamy(含乳脂的)? If you’re ordering sandwiches with special sauce or mayo, then you’re eating a lot more calories and fat grams than you think you are. Some sauces can add more than 20 grams of fat, and hundreds of calories to your lunch. Mustard(芥茉)is a good alternative. It’s flavorful, and has virtually no calories or fat.
Take a look at what you’re doing, and make changes you can live with.

Say you are a 17th century construction worker who’s worked hard to build a splendid tower for the dead wife of your emperor.
Now say that the emperor orders your fingertips cut off so your can never build another one . Yes, this story is about the Taj Mahal, one of the most famous buildings in the world. And
the tale behind the construction is just as impressive as the building itself.
First, there’s the emperor of northern India, Shah Jehan, also called the King of the World.
In 1612, Shah Jehan married Mumtaz Mahal. Mad in love, they had 14 children over the next 20 years. But then sadness came. As Mumtaz was about to give birth to child number 14, she said she heard her unborn baby cry out. It was a sign of death. And as Mumtaz lay dying ,
she asked Jehan to build a lasting memorial（纪念物）to celebrate their love.
The heartbroken Jehan ordered his wife’s dying wish carried out, and more than 20,000 workers worked nearly 2 years to complete the construction. In 1653, Jehan placed Mumtaz’s remains under the center of the building.
Later, son number five, Aurangzeb, murdered his brothers and took over the power from his aging father. Jehan lived the rest of his days, eight years, imprisoned not far from the Taj Mahal. Jehan was only allowed to climb onto the top of his prison to see the timeless treasure from a distance. But never again would he be allowed to visit it until he was buried next to his wife.
Today, 25,000 people visit the Taj Mahal each day. Though the reason for building the tower was a strange and sad story, people who see its breath-taking beauty are reminded of the happiness that inspired its construction.

Crime has its own cycles, a magazine reported some years ago. Police records that were studied for five years from over 2,400 cities and towns show a surprising link between changes in the seasons and crime patterns.
The pattern of crime has varied very little over a long period of years. Murder reaches its high during July and August, as do other violent attacks. Murder, moreover, is more than seasonal: it is a weekend crime. It is also a nighttime crime: 62 percent of murders are committed between 6 p.m. and 6 a.m. Unlike the summer high in crimes of bodily harm, burglary has a different cycle. You are most likely to be robbed between 6 p.m. and 2 a.m. on a Saturday night in December, January, or February. What is the most uncriminal month of all? May — except for one strange statistic. More dog bites are reported in this month than in any other month of the year.
60. The main idea of paragraph 1 is _________.
A. crime is a serious social problem
B. there is a link between changes in the seasons and crime patterns
