CFood 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.51. Which of the following statements is NOT true?A. Food when poisoned can make people sick.B. Food poisoning means death.C. Food poisoning comes in varieties.D. Food poisoning can be serious.
In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:The more the man ran, the greater loss of body fat.The more they ran, the greater their increase in food intake.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.1、What kind of physical problem do many adult Americans have?____A、They are too slim.B、They work too hard.C、They are too fat.D、 They lost too much body fat.2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____A、 30.B、 50.C、100.D、150.3、Is there scientific evidence to support that eating too much is the cause of a "weight problem"?____A、Yes, there is plenty of evidence.B、Of course, there is some evidence to show this is true.C、There is hardly any scientific evidence to support this.D、We don't know because the information is not given4、In comparison with the adult American population today, the Americans of ____.A、ate more food and had more physical activitiesB、ate less food but had more activitiesC、 ate less food and had less physical exerciseD、had more weight problems5、What have modern medical and scientific researches reported to us?____A、Fat people eat less food and are less active.B、 Fat people eat more food than slim people and are more active.C、 Fat people eat more food than slim people but are less active.D、 Thin people run less, but have greater increase in food intake.

问答题Practice 3 Directions: Read the text below. Write an essay in about 120 words, in which you should summarize the key points of the text and make comments on them. Try to use your own words. All of us should keep a kitchen diary, showing how much food is left uneaten as garbage. In China, enough food is wasted in restaurants every year to feed 200 million people. In the United States, 40 percent of food is wasted from farm to fork. Each year, the amount of food thrown away in rich countries is almost the same as that produced in sub-Saharan Africa. This raises some important questions. In developing countries, food is lost because farmers do not have appropriate cooling, storage or market access for their crops. Their grains, fruits and vegetables dry up and rot away. In developed countries, the picture is different, and food is wasted in supermarkets, restaurants and at home. China faces both problems, significant losses in farms, as well as at the sale and consumption stages. And the amount of food wasted by Chinese consumers is rapidly increasing. Consumer culture has filled China and urban residents can get quality food from anywhere in the country and from across the planet. Chinese consumers are as particular about their food as those in other countries. In supermarkets, they refuse to buy vegetables that don’t look fresh or have an irregular shape, or milk and other products close to their expiry (失效) date. Should Chinese consumers take more responsibility for the waste they create? Everyone deserves to have enough food to eat. Despite China’s impressive success in reducing hunger over the past three decades, the job is not completed yet.

问答题Practice 1 Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods—a term whose meaning varies greatly—frequently proclaim that such products are safer and more nutritious than others. The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore.
