On a hot summer day, a soft drink can really take away your thirst. At home, at school, in the park or at the movies—you can find one almost anywhere.
Carbonated(碳酸的)
You can see bubbles in these! Of all soft drinks sold, about 75 percent are carbonated. But be careful, carbonated soft drinks have lots of sugar and caffeine. Caffeine is not very good for you in the summer, because it takes water out of your body. And the sugar can make you overweight if you drink too much.
Fruit juice
There are different kinds of juice. One kind is made only from fresh fruit. This kind of fruit juice may not taste sweet enough for some people, but it is nutritious. Another kind of fruit juice tastes good but has lots of sugar in it. Many young people buy this kind because the advertisements are good. It is bad for your teeth and bones to drink lots of this.
Energy drinks
These kinds of drinks have caffeine and things that make people get excited in them. They are sometimes called “party drinks”. Doctors say that if you drink too much of this kind, you may have a heart attack.
Bottled water
We have lots of different kinds of bottled water, such as mineral water, purified water and distilled(蒸馏的) water. They are clean and easy to drink. But it is best not to drink very cold water. It may make your stomach feel bad.
Sports drinks
Most of these have funny names like “Scream” and “G-Vital”. They have lots of vitamins and minerals in them. After you play sports, you may want to drink one of these.
But if you just spend your summer holiday sitting around watching TV, you won’t need them at all!

China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylamide glycol （[化]乙二醇）, a low – cost substitute commonly used in automobile antifreeze（防冻剂）.
Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.

One reaction to all the concern about tropical deforestation（砍伐森林） is a blank（茫然的） stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
The underlined word "synthetics" probably means .

A．natural rubber	B．tropical materials
C．man-made material	D．commercial rubber

In the last paragraph the author tries to .

A．tell people how to avoid the tropical deforestation

B．persuade people to buy something synthetic

C．show us how important it is to protect the tropical forests

D．let people realise the effect of tropical deforestation

According to the passage, which of the following is NOT true?

A．The forests are losing their function in turning carbon dioxide into oxygen.

B．Many of our daily uses are related to the tropical forests.

C．Tropical plants can be used to make industrial products.

D．High carbon dioxide levels will make the earth warmer.

The author's attitude towards the tropical deforestation is .

A．puzzling

B．cold

C．supporting

D．opposed

Which of the following might be the best title for the passage?

A．Tropical Forests	B．Saving the Tropical Forests
C．Tropical Forests and Our Life	D．The Greenhouse Effects

Napoleon Bonaparte died on May 5, 1821, on the island of St. Helena off the coast of Africa. He was 51 years old at the time. When doctors examined Napoleon's body, they said that the former emperor of France had died from cancer of the stomach. That was the cause of death recorded in the official report. However, other doctors disagreed. One doctor who was present during the examination of the body said that Napoleon died of hepatitis（肝炎）. Other historians and medical experts have suggested that Napoleon died of syphilis（梅毒）, tuberculosis（肺结核）, or perhaps malaria. Now, after careful research, a British chemist thinks that Napoleon might have been poisoned -- not by a person, but by his wallpaper.
Napoleon was sent to the island of St. Helena in 1815 after he lost the battle of Waterloo. He was a prisoner on the island. Although he had servants to attend to him, he had to live in one small building. St. Helena is a very wet island, so the walls of the building were always covered with mold. Napoleon became ill from spending too much time inside his house. Almost constantly he had a fever, chills, and felt sick to his stomach. He often felt pain in his shoulders and in his side. His skin turned yellow. He got frequent headaches, and he would become dizzy and vomit. None of the medicine that the doctors gave Napoleon seemed to help. They were not sure what was the matter. Finally, Napoleon was too weak to leave the house. One night, while he was sleeping, he went into a coma （昏迷）and died.
Many doctors who later reviewed the reports of Napoleon's illness found that the symptoms did not show a man who suffered from stomach cancer. It seemed obvious that Napoleon had died from some other cause. In 1961, a Swedish doctor examined some of Napoleon’s hair and found a high level of arsenic（砒霜）, a chemical poison. Was Napoleon murdered? It is doubtful. Arsenic was used in many types of medicine during Napoleon’s time, so he might have taken the arsenic as a cure for his illness. Then, in 1982, Dr. David Jones from England began to look into the mystery and suggested that Napoleon might have breathed in arsenic which was in the air of his house. In the 1700s and 1800s, arsenic was used to make a kind of green paint used on cloth and wallpaper. If the paint was used on a wet wall, the arsenic would go into the air. A person in the room might breathe that air. After studying the wallpaper in the room where Napoleon died, Dr. Jones found high levels of arsenic in the green paint on the walls.

My newly-rented small apartment was far away from the centre of London and it was becoming essential for me to find a job, so finally I spent a whole morning getting to town and putting my name down to be considered by London Transport for a job on the underground. They were looking for guards, not drivers. This suited me. I couldn’t drive a car but thought that I could probably guard a train, and perhaps continue to write my poems between stations. The writers Keats and Chekhov had been doctors. T.S. Eliot had worked in a bank and Wallace Stevens for an insurance company. I’d be a subway guard. I could see myself being cheerful, useful, a good man in a crisis（艰难危险时期）. Obviously I’d be overqualified but I was willing to forget about that in return for a steady income and travel privileges — those being particularly welcome to someone living a long way from the city centre.
The next day I sat down, with almost a hundred other candidates, for the intelligence test. I must have done all right because after about half an hour’s wait I was sent into another room for a psychological test. This time there were only about fifty candidates. The interviewer sat at a desk. Candidates were signaled forward to occupy the seat opposite him when the previous occupant had been dismissed, after a greater or shorter time. Obviously the long interviews were the more successful ones. Some of the interviews were as short as five minutes. Mine was the only one that lasted a minute and a half.
I can remember the questions now: “Why did you leave your last job?” “Why did you leave your job before that?” “And the one before that?” I can’t recall my answers, except that they were short at first and grew progressively shorter. His closing statement, I thought, revealed a lack of sensitivity which helped to explain why as a psychologist, he had risen no higher than the underground railway. “You’ve failed the psychological test and we are unable to offer you a position.”
Failing to get that job was my low point. Or so I thought, believing that the work was easy. Actually, such jobs — being a postman is another one I still desire — demand exactly the sort of elementary yet responsible awareness that the habitual dreamer is least qualified to give. But I was still far short of full self-understanding. I was also short of cash.

A．he wanted to work in the centre of London

What does the writer realize now that he did not realize then?

A．How unpleasant ordinary jobs can be.	B．How difficult it is to be a poet.
C．How unsuitable he was for the job.	D．How badly he did in the interview.

What’s the writer’s opinion of the psychologist?
