[单项选择]We all have ups and downs, and usually it’s just best to accept them. But perhaps you are concerned about someone who seems to be depressed. Then how can you help them Here are a few tips.
Get the person to talk. Try to get him or her to tell you not only about the depression itself, but about fears, wishes, or losses that underlie it. This is often difficult, of course, but it can be very useful. If nothing else, it will reassure the person that someone cares.

Keep the person active. Depression causes tiredness, which leads to more depression, and so on. Productive or entertaining activities can help break the vicious cycle. Very often a change of scene or a vacation can be effective.
If you are struggling with depression yourself, make yourself do something, however small it may seem. Make your bed or clean up your room, for example. You will be able to tell yourself you’ve accomp

These organisations are often very small and need money to keep going. To help them out, why not give some canned or dried food or give them money.

[单项选择]Passage Two
Conventional wisdom has it that concern for the environment is a luxury only the rich world can afford; that only people whose basic needs for food and shelter have been met can start worrying about the health of the planet. This survey will argue that developing countries, too, should be thinking about the environment. True, in the rich countries a strong environmental movement did not emerge until long after they had become industrialized, a stage that many developing countries have yet to reach. And true, many of the developed world’s environmental concerns have little to do with immediate threats to its inhabitants’ well-being. People worry about whether carbon-dioxide emissions might lead to a warmer climate next century, or whether genetically engineered crops might have unforeseen consequences for the ecosystem. That is why, w

[简答题] Students who score high in achievement needs tend to make higher grades in college than those who score low. When degree aptitude for college work, as indicated by College Entrance Examination Board Tests, is held constant, engineering students who score high in achievement needs tend to make higher grades in college than the aptitude test scores would indicate. We can define this need as the habitual desire to do useful work well. It is a salient influence characteristic of those who need little supervision. Their desire for accomplishment is a stronger motivation than any stimulation the supervisor can provide. Individuals who function in terms, of this drive do not "bluff" in regard to a job that they fail to do well. Some employees have a strong drive for success in their work; others are satisfied when they make a living. Those who want to feel that they are successful have high aspiration for themselves. Thoughts concerning the achievement drive are often prominent
