Nowadays, science is developing at a high speed. With the development of science, many countries have improved their economy and raised their people’s living standards. Therefore, science is of great benefit to our daily life.
If we look at the things around us, we’ll find how closely our everyday life is related to science. In one case, at home we can turn on the central heating or air conditioner when we feel cold or hot, and we can watch TV or listen to the tape recorder for entertainment, and we can use a gas stove to cook our meals, and we have computers to help us with our work when we are working in the office, and we also have cars, buses, even planes as traffic tools when we go out. All these things are the results of the scientific development. It goes
without saying that without science our society cannot make rapid progress and our life cannot be comfortable and convenient.
Now that science is so significant in our daily life, we should try to make as many contributions as possible to the development of science. As college students, we must first of all study hard to gain useful scientific knowledge, and then put what we have learnt into practice. We should make the most of science to serve our society.

With the advance of human society, along with the development of modern science and technology, people are faced with an increasing number of pollutions. One of the severe pollutions is noise pollution. Many parents express their complaints over noise pollution, especially car alarms.
Anchor
Almost anyone who has lived in a big city can tell you how irritating it is to be awakened in the middle of the night by the wail of a car alarm. The loss of sleep can drive you crazy, but this is just one in a long list of problems that such high decibel noises can cause.
Jonathan
People in this noisy neighborhood in upper Manhattan are fed up with car alarms. They're angry enough at being jolted awake several times a week, but more than that they worry about what effect these alarms will have on their children. Already studies have shown that continuous exposure to high-decibel noise can cause an increase in heart rate and blood pressure.
Andrea
By the time my child can read, he will already have been exposed to the constant roar of the traffic, but the intense siren of a car alarm is way above the level of safety.
Michael
I have a valid concern. According to the National Institute of Occupational Safety and Health (NIOSH), exposure to noise above 85 decibels for 8 hours or more is a danger to your health. City traffic and trucks are about 90 decibels. The siren of a car alarm is about 120 decibels, about the same as a plane taking off.
The parents here are sick and tired of listening to the shrill siren of car alarms. However, it's for their children that they are most concerned. They've started a group called Parents to Silence Car Alarms. They don't think that making the owner of a car pay a fine is enough. These parents have started a campaign to have car alarms banned.
1.According to the passage, which one of the following statements is true?
A. Anchor thinks the high decibel noises only causes the loss of sleep.
B. Jonathan holds the view that exposure to decibel noises can give rise to heart disease.
C. According to NIOSH, exposure to noise above 85 for 8 hours or more threatens people's health.
D. Andrea believes the intense siren of a car alarm is acceptable.
2.According to the passage, what is the parents' attitude towards car alarms?
A. Neutral. B. Critical. C. Favorable. D. Indifferent.
3.What is the main idea of the passage?
A. People in modern society is faced with noise pollution.
B. Anyone who lives in a big city is tired of car alarms.
C. A car alarm is out of control and beyond the level of safety.
D. Parents complain about car alarms, trying to fight against them.
