Scientist Robert winter has found out that when it is really bad their water pipes snap from the tension like rubber bands. When that happens, the whole plant vibrates a little. The snapping pipes make noises ten thousand times more quiet than a whisper.
Robert knows that healthy, well-watered plants are quiet. He also knows that many insects prefer attacking dry plants rather than healthy plants. How do the insects know which are healthy plants and which are not? Robert thinks that the insects may listen for the plants that cry and then they may buzz in to kill.
To test his theory, Robert is using a device that can imitate plant cries. He attaches it to a quiet, healthy plant so the plant sounds thirsty. Then he watches insects to see if they attack more often than usual.
If he is right, scientists could use the insects' ability against them. They could build traps that imitate crying plants. So when the insects buzz in to eat, they won't buzz out.
14. What do plants do when they are thirsty?
15. What plants do many insects tend to attack?
16. What could scientists do if Robert's theory proves to be true?
Passage 3
People enjoy taking trips, but what are the reasons they leave home? One reason is for education. People travel because they want to broaden their horizons to learn about other people and other places. They are curious about other cultures. When people are tourists, they get a quick look at different ways of living. Even a short look at another kind of lifestyle is an important lesson.
On a trip, a person can learn directly — by visiting museums and historic spots. What does a tourist learn who sees the art museums, visits the historical palaces and other scenic spots in Paris, and shops along the River Seine? he gets a vivid picture— a real-life—one of the French people. He learns about their attitudes, how they feel about business, beauty and history.
What about the tourist who goes to Hongkong? Does he get the same information that he could get from a book? he might read that Hongkong is crowded, that there is less than 200 square meters of space for each person, but seeing and feeling the lack of space will impress him much more. He might read that there are nearly 200 vehicles for every kilometer of roadway, but the sight of so many vehicles parked along the roadside will be a much more vivid lesson. the tourist to Hongkong will never forget the contrasts — the straight vertical lines of the tall modern buildings and the moving lines of boats that people live in.
17. Why do people leave home to travel according to the passage?
18. What do we learn from the passage about Paris?
19. What impression will a tourist get of Hongkong?
20. What does the passage tell us about travelling?

How I Finance My College Education
With the rapid development of higher education in China, and more high school graduates admitted, universities can no longer be financed exclusively by the government and students must pay at least partly for their schooling.
There are various ways for a student to pay his tuition and fees. To begin with, if the student is quite excellent in his studies, he can apply for scholarship. Secondly, especially in China, he can always depend on his parents for all kinds of expenditure, including living allowances. Then, he can choose to turn to the bank for a loan to pay his way through university, which he can repay after graduation. If he finds all the above not desirable, he still had another road to take-to do a part-time job and work his way through.
In my case, I am fortunate enough to be born into a well-to-do family and have no difficulty having my parents pay for all my fees. But as a college student, I dislike a totally dependent existence, so I am working part-time as a newspaper-boy to help support myself. And I am also studying hard, hoping to win some scholarship or awards one day so that I can be wholly self-reliant and independent.
