We’re surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.
Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin. Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us.
Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can’t be mixed with vinegar, because it can produce poisonous gas. Without chemistry, we wouldn’t have fireworks displays on important days.
Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw food. Baking is a great example of chemistry. Too much or too little of any ingredient makes a difference to the result of baking, for example, the dough (面团) won’t rise or the cake will be flat.
Chemistry isn’t something that just lives in a lab; it’s something that you meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest looking things.What’s the main idea of Paragraph 1?

If the security is in place, a letter will appear in the bottom right－hand corner of your screen. The Web site address may also start https: // － the extra “s” stands for secure. If in doubt, give your credit－card information over the telephone.

In recent years, especially during the l960s, there was much discussion about “the brain drain (排干, 流失),” which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment．For example, according to a report from U．N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad．Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries．Probably the greatest brain drain occurred among young scientists who had gone abroad to study．Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home．The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia.
Recent studies show that the brain drain to the United States may be decreasing．Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries．The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too．However, in the field of medicine the drain to the United States still goes on．Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year．Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.Which of the following is not the reason for “the brain drain”?

It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day. Some visitors from the city arrived. The told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other place.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was 
reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a batter future. But the dream didn’t last long.
