Question

    Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.

At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice(精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.

Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.

1.The underlined word “cure” in Paragragh 1 probably means ______.

A.a medical treatment B.a kind of vitamin

C.a kind of germ D.a kind of rice

2.Why did Christian Eijkman raise some chickens?

A.To eat them. B.To carry out his experiments.

C.To give the Javanese a surprise. D.To make money by selling them.

A.beri-beri was caused by chickens

B.the Javanese didn’t like vitamins

C.Christian Eijkman’s experiment was successful

D.the Javanese’s disease was caused by a kind of germ

2.B

3.C

【解析】

这是一篇记叙文。文章主要讲述了Christian医生为了找到爪哇岛人所得怪病的治疗办法，自己亲自在那里养鸡做实验，结果通过实验发现当地人生病是因为没有摄入足够的维生素，从而治好了当地人的病，也让人们意识到维生素的重要性。

1.

词句猜测题。从文中“Many people on the island had a disease called beri-beri.”可知，在爪哇岛很多人得了一种怪病，在这种情况下，Christian医生做出决定“He was going there to try and find a cure.”，由此可知他要去那里试着寻找治疗的方法，所以cure在这里是指a medical treatment“医学治疗”，故选A项。

2.

细节理解题。从本中“He raised some chickens. He didn’t eat them, but made experiments on them.”可知，Christian医生养鸡，他不是为了吃鸡，而是要用鸡做实验。故选B项。

3.

推理判断题。从文中第二段“Eijkman realized that he had made an important discovery — that some things in food could prevent disease.These things were named vitamins. ”可知，艾克曼意识到他有一个重要的发现——食物中的某些东西可以防止疾病。这些东西叫做维生素，所以通过养鸡实验发现了怪病的病因，由此判断出，养鸡实验是成功的，故选C项。
