Question

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.

【小题1】B

【小题2】A

【小题3】B

【小题4】D

【小题5】C

解析:

【语篇解读】本篇文章为说明文。说明了什么是食物中毒以及它常见的症状，导致食物中毒的原因，如何正确处理食物以减少中毒的可能，最后说明了食物中毒并不可怕，只要休息几天或多喝开水即可痊愈。

【小题1】细节理解题。根据第一段第三句“but some types are deadly”可知虽然食物中毒并不是很严重，但是有的也会致命，因此选D项。

【小题2】细节理解题。根据第一段最后一句“Fever is one of the most common symptoms.”可知A项正确，意为“食物中毒常伴有发烧症状”。

【小题3】细节理解题。第二、三、四段分析食物中毒的原因，由每段的第一句主题句即可知A、C、D三项为原因，故选B项。

【小题4】细节理解题。根据第五段第一句“When people handle food properly, the risk of food poisoning is very small。”；因此，只要合理地处理食物，中毒的可能性还是很小的，故选D项。A项去掉了wild这一定语，概念扩大了。B、C两组概念在文章中没有作对比，也不能选。

【小题5】推理判断题。根据第一段第三句“Food poisoning is usually not serious,”和最后一段可以推断出食物中毒并不可怕，是完全可控的。故选C项。
