The African elephant, the largest land animal remaining on earth, is of great importance to African eco-system. Unlike other animals, the African elephant is to a great degree the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna（大草原）surroundings in which it lives, therefore setting the terms of existence for millions of other animals and live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed（有蹄的）plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole eco-system.

Quality after-school programs are designed to improve academic performance, decrease youth crimes and other high-risk behaviors, and help young people grow into healthy, successful adults.
The effect of quality after-school programs on academic performance is clear. Studies show that students who take part in such programs show better work habits, higher rates of homework completion, improved grades, and higher scores on achievement tests. They also have fewer absences and are less likely to blame. After-school programs also influence high-risk teen behavior. Various studies show decreased rates of crime, drug-taking, and teen sex among youth who join in well-run after-school programs when compared to similar youth who do not. Finally, after-school programs play an important role in supporting different kinds of fields of development: physical development, mental development and social development. Thus, one can safely say that after-school programming is an effective method to help young people become contributing members of society.
Although there is enough proof from both small and large assessments that after-school programs can make a positive difference, it is important to note that not all programs are equal. First, dosage matters -- young people who attend the most hours over the most years benefit more than members who attend less often or over a shorter period of time. Next, after-school programs make a bigger difference for those students who need help most and have the fewest choices. Finally, program qualities matter. After-school programs work best when they create unique opportunities for youth. They should provide opportunities, skill building meaningful involvement, expression, suggestion, service, and work. Staff characteristics make an important difference in the quality of a program. The adults should treat youth as partners, create safe and fair environment, encourage personalized involvement, and actively create learning opportunities. In short, although after-school programs have a promising future, how they are designed and run matters.

Many Chinese students who have learnt English for more than ten years are still unable to speak English very well when they meet a foreigner. They seem to have mastered the basic language structure(结构), but a conversation in English will make them feel uneasy. They are afraid that other people might find out their mistakes.
It's uncommon that many students who are bad speakers of English can write English perfectly. This proves that they are unable to organize their idea in English. The center of the problem is that they lack practice and confidence (自信).

What exactly is a lie ?Is it anything we say which we know is untrue ?Or is it something more than that ?For example, suppose a friend wants to borrow some money from you. You say “I wish I could help you, but I am short of money myself.” In fact , you are not short of money but your friend is in the habit of not paying his debts and you don’t want to hurt his feelings by reminding him of this. Is this really a lie ?
Professor Jerald Jellison of the University of southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it’s terrible. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise that they have no intention of carrying out. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at :the lie from which the liar hopes to profit or gain in some way.
Research has been done into the way people’s behavior changes in a number of small, unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now”. They also tend to touch certain parts of the face, particularly the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose is very sensitive to changes and the increased pressure makes it itch.
Another gesture that gives liars away is what the writer Decmond Morris in his book Man Watching calls the “mouth cover”. He says that there are several typical forms of this ,such as covering part of the mouth with the fingers, touching the upper lip or putting a finger of the hand at one side off the mouth. Such a gesture can be understood as an unconscious(未察觉的) attempt on the part of the liar to stop himself from lying.
Of course, such gestures as rubbing the nose or covering the mouth , moving about in a chair can not be taken as proof that the speaker is lying. They simply tend to happen more often in this situation. It is one gesture alone that gives the liar away but a whole number of things , and in particular the context(上下文) which the lie is told.According to the passage, a white lie seems to be a lie ______.
| A．that other people believe |
| B．that other people don’t believe |
| C．told in order not to hurt someone’s feelings |
| D．told in order to take advantage of someone |
Research suggests that women _____.
| A．are better at telling less serious lies than men |
| B．generally lie for more than men do |
| C．often make promises they intend to break |
| D．lie at parties more often than men do |
Researchers find that when a person tells lies _____.
| A．his blood pressure increases measurably |
| B．he looks very serious |
| C．he is likely to make some small changes in his behavior |
| D．he uses his unconscious mind |
The writer of the passage______.
| A．hates lying | B．enjoys lying | C．often tells a lie | D．tries to study about lying |
Which of the following is not mentioned in the passage as a sign of lying ?
| A．Touching one’s ears | B．Rubbing the nose |
| C．Moving in a chair | D．Covering the mouth |
