Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release（释放）poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.Which of the following statements is NOT true?

The man sitting opposite Robert was the Financial Controller. Everybody called him “the FC” for short. He made all the decisions about money. Robert needed some more. That was why he had to see him. The two men did not get on very well. In fact, they had always disliked each other.
“Your request is out of the question,” the FC said. Robert had difficulty in controlling himself, but he managed somehow. He explained that he wanted the money in order to make more programmes.
“And why do you want to do that?” the FC asked sharply. Again, Robert almost lost his temper. “Because more and more people are listening to my department’s programmes. There’s great demand for them,” he answered.

Baths and bathing have long been considered of medical importance to man. In Greece there are the ruins of a water system for baths built over 3,000 years ago. The Romans had warm public baths. In some baths, as many 3,000 persons could bathe at the same time.
Treating disease by taking bathing has been popular for centuries. Modern medical bathing first became popular in Europe and by the late 1700’s has also become popular in the United States.
For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to keep clean was avoided , and perfume was often used to cover up body smells!
By the 1700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently. During the Victorian Age of the late 19th century, taking a bath on Saturday night became common.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “The Great Unwashed!” In one American city , for example, a person was only allowed to take a bath every thirty days! That was a law!
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health, Doctors know that dirty bodies increase the chance of diseases. As a result, in the United States, people generally bathe often. Some people bathe once a day at least. They consider a daily bath essential to good health.A water system for baths was built by _______ over 3,000 years ago.

The Antarctica is actually a desert. It is the only continent on the earth without a river or a lake.
The Antarctica is all ice all year round. The warmest temperature ever recorded there is zero, at the South Pole. Explorers used to think that a place so cold would have a heavy snowfall. But less than ten inches of snow falls each year. That is less than half an inch of water. Ten times that much moisture (水份) falls in parts of the Sahara.
The little snow that falls in Antarctica never melts. It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about eighty feet deep it is turned to ice by the weight of snow above it .Antarctica is called a desert because it_______.
| A．is sandy. |
| B．has the same temperature as a desert. |
| C．has little moisture and no lakes or rivers. |
| D．there are no people there. |
Antarctica has_______.
| A．ten times as much moisture as the Sahara. |
| B．the same amount of moisture as the Sahara. |
| C．about one—tenth of the moisture of the Sahara. |
| D．none of the above. |
The snow in Antarctica is very deep because it_______.
A. never stops falling.B. piles up year after year.
C. never melts. D. both B and C.The snow turns to ice when______.

With the development of society, the choice of food and drinks for children is more diversified(多样化) than ever before. However, every coin has two sides. Many facts suggest that children are overweight and the situation is getting worse, according to the statistics(数据统计). I feel there are a number of reasons for this.
Some people blame（责怪）the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree to this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers. Not only is this an unhealthy pastime（消遣）, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as guiding them away from fast food shops and bad eating habits.What is suggested by the author to deal with “overweight”?
| A．Blaming the shops selling unhealthy and fatty foods. |
| B．Asking young children to walk to school every day. |
| C．Living an active life and giving up bad eating habits. |
| D．Not watching TV or playing computer games after school. |
