Question

【題目】根據(jù)短文內(nèi)容選擇最佳答案。
MSG(monosodium glutamate谷氨酸單鈉) is a food additive(食品添加劑),which has been widely used by many food factories all over the world since it appeared first in Japan in 1909.
MSG is a substance that is added to some food to improve its taste and color. It is used in foods around the world such as cakes, bread, frozen meat, fish and vegetables. In the beginning, people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed to have bad reactions(反應(yīng)) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat . It was also reported that MSG excited a person's brain and caused his death in Japan. Scientists think that MSG may lead to many neurological disorders(神經(jīng)紊亂). In mice studies done by a university, the result showed the mice didn't want to eat the food including MSG.
Today many food companies “hide” MSG on food labels(標(biāo)簽) by using different names. If you see “natural flavorings (調(diào)味品) ”,“hydrolyzed protein” and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very delicious to taste, but sometimes it is dangerous for our health because some harmful food additives have been added to the food.
To protect people's health, our governments, from central to local, are taking action to stop factories producing harmful food additives.

【答案】
（1）B
（2）A
（3）D
（4）C
（5）B
【解析】本文介紹了MSG是一種食品添加劑，對(duì)人體有害�，F(xiàn)在很多食品里還有這種添加劑，只是用了不同的名字。為了保護(hù)人們的健康，我們的政府正在采取行動(dòng)，阻止工廠生產(chǎn)有害的食品添加劑。

（1）細(xì)節(jié)理解題。根據(jù)第一段的MSG(monosodium glutamate谷氨酸單鈉) is a food additive(食品添加劑),可知谷氨酸單鈉是一種食品添加劑，故選B。

（2）細(xì)節(jié)理解題。根據(jù)第二段的It is used in foods around the world such as cakes, bread, frozen meat, fish and vegetables.可知MSG經(jīng)常被用于蛋糕、面包、凍肉、魚和蔬菜中。故選A。

（3）推理判斷題。根據(jù)第二段的Scientists think that MSG may lead to many neurological disorders(神經(jīng)紊亂). In mice studies done by a university, the result showed the mice didn't want to eat the food including MSG.可知MSG可能會(huì)導(dǎo)致神經(jīng)紊亂，在對(duì)老鼠的研究中發(fā)現(xiàn)，老鼠不想吃含有MSG的食物，故推斷MSG有時(shí)是不安全的。

（4）推理判斷題。根據(jù)第三段的Today many food companies “hide” MSG on food labels(標(biāo)簽) by using different names. If you see “natural flavorings (調(diào)味品) ”,“hydrolyzed protein” and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label.可知現(xiàn)在MSG用不同的名字，如果你在食物標(biāo)簽看到natural flavorings (調(diào)味品) ”,“hydrolyzed protein” 和 “spices”，這是你看到的MSG的隱藏方式，故推斷食物標(biāo)簽上有這些東西，可以知道里面添加了MSG，故選C。

（5）詞義猜測(cè)題。根據(jù)第二段的that is added to some food to improve its taste and color可知被加入食物中的，用于提高食物的味道和顏色，故此處這是一個(gè)材料，故選B。
