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（釋放）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.

Answer 1

【小題1】B

【小題2】A

【小題3】B

【小題4】D

【小題5】C

解析:

【語篇解讀】本篇文章為說明文。說明了什么是食物中毒以及它常見的癥狀，導(dǎo)致食物中毒的原因，如何正確處理食物以減少中毒的可能，最后說明了食物中毒并不可怕，只要休息幾天或多喝開水即可痊愈。

【小題1】細(xì)節(jié)理解題。根據(jù)第一段第三句“but some types are deadly”可知雖然食物中毒并不是很嚴(yán)重，但是有的也會(huì)致命，因此選D項(xiàng)。

【小題2】細(xì)節(jié)理解題。根據(jù)第一段最后一句“Fever is one of the most common symptoms.”可知A項(xiàng)正確，意為“食物中毒常伴有發(fā)燒癥狀”。

【小題3】細(xì)節(jié)理解題。第二、三、四段分析食物中毒的原因，由每段的第一句主題句即可知A、C、D三項(xiàng)為原因，故選B項(xiàng)。

【小題4】細(xì)節(jié)理解題。根據(jù)第五段第一句“When people handle food properly, the risk of food poisoning is very small�！保灰虼�，只要合理地處理食物，中毒的可能性還是很小的，故選D項(xiàng)。A項(xiàng)去掉了wild這一定語，概念擴(kuò)大了。B、C兩組概念在文章中沒有作對(duì)比，也不能選。

【小題5】推理判斷題。根據(jù)第一段第三句“Food poisoning is usually not serious,”和最后一段可以推斷出食物中毒并不可怕，是完全可控的。故選C項(xiàng)。
