Other reasons they take that first drink are to be rebellious (反抗的), for curiosity or "kicks" (刺激) or to escape an unpleasant environment. And young people drink and use drugs because alcohol (酒精) and drugs are at hand.
After first experimental use, young people continue to drink or use drugs because they believe these substances can relieve boredom, increase energy, decrease anxiety, solve problems, or help them socially. They may simply like the "high" they get in the early and middle stages of substance use. After continued use, they will drink or use drugs because they become physically and psychologically (心理地) addicted (上瘾的).
Now that we have admitted that we have to solve this problem. We must decide how to deal with this challenge. Winning this will take a great effort involving local, state, and national government. It will require the effort of schools, but it cannot be done by schools alone. It will take family and com munity involvement. Already a great amount of time, energy and expert knowledge has been directed toward dealing with it but the problem continues.
Which of the following is not mentioned as the reason of drinking and using drugs in the passage？
A．the selling of alcohol and drugs
B．pressure from their parents and relatives
C．curiosity
D．their eagerness to experience what is not permissible to them
第4题
Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that already faces enough stress.
But noise is not a new problem. In ancient Rome, people complained so much about noise that government stopped chariots (四轮马车) from moving through the streets at night!
Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise--if we shout loudly enough about it.
Why are scientists surprised by the findings in their noise study？
A．Because the world is becoming more and more noisy.
B．Because they have learned that noise is also a kind of pollution.
C．Because noise is an unwanted waste for human beings.
D．Because people knew little about noise before.

Other reasons they take that first drink are to be rebellious(反抗的), for curiosity or "kicks" (刺激)or to escape an unpleasant environment; And young people drink use drugs because alcohol(酒精) and drugs are at hand.
After first experimental use, young people continue to drink or use drugs because they believe these
substances can relieve boredom, increase energy, decrease anxiety, solve problems, or help them
socially. They may simply like the "high" they get in the early and middle stages of substance
use. After continued use, they will become physically and psychologically(心理地)addicted(上瘾的).
Now that we have admitted that we have to solve this problem, we must decide how to deal with this
challenge. Winning this will take a great effort involving local, state, and national government. It will
require the effort of schools, but it cannot be clone by schools alone. It will also require family and
community involvement. Already a great amount of time, energy and expert knowledge has been directed
toward dealing with it but the problem continues.

How will scientists do this？ People can' t go to the stars. The stars are far away. A person would take hundreds of years to the next star in a spaceship. So scientists are sending out radio signals. These signals travel in space at the speed of light. At that speed, radio signals will take 25 years to reach the next star. The signals ask "Is there anyone out here？". Living things in space must have machines to hear the signals. We will not get an answer to our signals for more than 50 years. However, scientists are already listening. Someone from space may be trying to send signals to us, too.
Scientists also have sent large telescopes into space. A telescope can make things look larger. The telescopes are going around the earth. They are looking for life on other worlds. In the next few years we may get an answer to the question, "Is there life in space.
People always thought about the question, ______.
A．How can scientists use machines to look for a star？
B．How far away are the stars？
C．How many years a person would take to go to the next star in a spaceship？
D．Is there life in space？

A scientist who wants to predict the way in which consumers(消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist were asked which of three groups borrow most—people with rising incomes, stable incomes, or 'decreasing incomes—he would probably answer, those with decreasing incomes. Actually, in the years 1947~1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions(假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true. The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months", she said, "we'll have to pay more for meat and milk; we'll have less to spend on other things". Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be disliked and buyers' resistance may be produced. This is shown by the following typical comment; "I just don't pay these prices; they are too high".
The investigations mentioned above were carried out in America; condition most helpful to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology(心理学).
According to the passage, if one wants to predict the way people spend their money, he should______.
A．rely on traditional assumptions about earning and spending
B．try to encourage or discourage consumers to spend money
C．carry out investigations on consumer behavior. and get data of consumers incomes and money spending motives
D．do researches in consumer psychology in a laboratory
