Everybody hates rats. But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We sent in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal (信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “‘Robots ’noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity(电)!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to and a rat would get out of it if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).In the world earthquake capitals, rats will become man’s best friends because they can .
| A．take the place of man’s rescue jobs |

Many college-bound freshmen are worrying about more than just who their roommates will be this fall. They may also be nervous about the well-known fact that they are likely to gain weight this school year. Or will they? While many of us remember the extra weight that showed up right around the start of our college careers, we are not always clear on how much weight we realize gained or why.
Many nutrition experts and psychologists think that it is the change in environment and the stress of a new beginning that cause the typical college freshmen to gain extra pounds. As students start a new stage of their lives, many eat to deal with the stress of change or loneliness. Often, college students are making meals or choosing foods independently for the first time in their lives. If they live in the college dormitory, they have a wide variety of foods to select from that may be higher in calories and fatter than the foods they consumed living at home. In addition, college social events usually center around food. I clearly remember sitting in my dorm cafeteria for two or three hours on a Saturday morning socializing with my new friends. Instead of eating only one meal, we would start with breakfast, eat throughout the duration of our socializing, and finish with lunch. Food also makes an appearance after late-night parties, as part of a school day, or simply to break the monotony(单调 ).
So will this year’s typical freshmen really gain 15 pounds? According to a 2006 Tufts University study, students enrolling in college this fall will gain weight, but maybe not the assumed 15 pounds. Based on the students surveyed, the study found that men can expect to gain an average of 6 pounds and women an average of 4.5 pounds during the freshman year.According to the passage, it is obvious that __________.
| A．the foods the freshmen had at home may be healthier than those in the dorm cafeteria |
| B．to break the monotony, the students should start with breakfast, and finish with lunch |
| C．the students should eat to deal with the stress of change or loneliness in new situations |
| D．the boys may gain less pounds than the girls during the first year in the college |
Nutrition experts and psychologists think that __________.
| A．students should get used to the stress of change through foods they had at home |
| B．the new environment and the stress have something to do with the students’ extra pounds |
| C．students should know in what way they gain so much weight |
| D．choosing foods independently can make people lose weight naturally |
From the writer’s experience, the writer thinks that ____________.
| A．foods in the dorm cafeteria are all higher in calories and fatter |
| B．the best way to break the monotony is through breakfast, lunch and supper |
| C．students in college will gain an average of about 5.25 pounds every fall |
| D．social events in the college are usually celebrated around food |
This passage is mainly about ______________.
A how and why the freshmen gain extra pounds
B. the experience of the freshmen in the college
C. the freshmen with trouble in a new environment
D. the views of the nutrition experts and psychologists about gaining weight

My grandfather worked as a carpenter. On this particular day, he was building some crates（木箱）for the clothes his church was sending to an orphanage in Brazil. On his way home, he found his glasses were gone. When he mentally replayed his earlier actions, he realized what happened. The glasses had slipped out of his pocket and fallen into one of the crates. His new glasses were heading for Brazil!
The Great Depression was at its height, and Grandpa had six children. He had spent twenty dollars for those glasses that very morning.
“It’s not fair,” he thought as he walked home angrily. “I’ve been very faithful in giving my time and money to my work, and now this.”
Several months later, the director of the orphanage came to the United States. He wanted to visit all the churches that supported him, so he came to my grandfather’s small church in Chicago.
He began by thanking the people for their kindness in supporting the orphanage. “But most of all,” he said, “ I must thank you for the glasses you sent last year. You see, some people had just come to the orphanage, destroying everything, including my glasses. I was desperate. Even if I had the money, there was simply no way of replacing those glasses. Along with not being able to see well, I experienced headaches every day, so my coworkers and I were very worried about this. Then your crates arrived. When I removed the covers, I found a pair of glasses lying on top.”
He paused long enough to let his words sink in. Then, he continued: “When I tried on the glasses, it was as though they had been made just for me!” The people listened, happy for the miraculous glasses. But they thought it was strange because there were no glasses on their list of items to be sent overseas.
Sitting quietly in the back, with tears streaming down his face, my grandfather, an ordinary carpenter realized his glasses had found a good place to go.The underlined word “miraculous”（Paragraph 6）can be replaced by.
| A．practical | B．wonderful | C．necessary | D．important |
What would be the best title for the text?
| A．The Perfect Mistake. | B．An Ordinary Carpenter. |
| C．A Careless Old Man. | D．A Pair of Glasses. |
Since the 1950s, most of the stars of pop music have come from Britain and America. However, in the last ten years, when many different kinds of music have established themselves on the pop scene, more and more stars have come from other countries.
Pop music changes all the time and new stars appear and become famous. For a musician to stay popular and still produced good, original music over a long period of time, is a sign of true star.
Most stars start their careers in a simple way---playing in unknown night clubs or dance-hall where people want to dance to the music, not listen to it. They may have continued doing this for many years until they get a “break”---a chance to perform in a well–known place or get a recording contract. To become a star is the aim of every singer or musician and the dream of many a pop-crazy teenager.
However a group or star makes it to the top, they can be sure that their lives will change once they are successful. Ordinary teenagers living at home with their parents may suddenly find themselves rich enough to buy their own houses. An established superstar may be able to buy several.
Despite the large amount of money that are earned, life at the top is not easy for many stars. The pop scene is hard work and many stars need to spend a lot of time away from home. For a lot of them, this means they have no home life and their personal relationships suffer. Despite great public success, life at the top can be very lonely.Since the 1950s, most of the stars of pop music have come from _________.
| A．America | B．America and Britain | C．America and Europe | D．other countries |
According to the passage, a “break” may mean a chance to ______.
perform in a well-known concert
C. play in dance-halls B. get a recording contract
D. meet a lot of pop-crazy teenagersIf a star becomes successful, he ______ according to the passage.
| A．will have an easy life because of the larger amount of money earned | |
| B．may have a happy home life and good person relationships | |
| C．will live at home with their parents | D．may have a lonely life |
Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life. We can infer from the text that humans and animals _________.
| A．depend on one sense in choosing food |
| B．choose food in similar ways |
| C．are not satisfied with their food |
| D．eat entirely different food |
Which of the following eats only one type of food?
| A．The white butterfly. | B．The bear. | C．The small bird. | D．The fox. |
Certain animals change their choice of food when ___________.
| A．the season changes |
| B．they move to different places |
| C．the food color changes |
| D．they are attracted by different smells |
We can learn from the last paragraph that __________.
| A．food is chosen for a good reason |
| B．some people have few choices of food |
| C．French and British food is good |
| D．some people care little about healthy diet |
