Christian Eijkman, a Dutch doctor, left ...

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.Christian Eijkman went to the island of Java to ______.

A. help the Javanese with their illness

1.A 2.D 3.B 【解析】 试题分析:本文介绍了人类发现维他命的过程:Christian Eijkman到Java帮助当地人治病,尽管发现当地人缺少一种物质,这种物质就是后来人们知道的维他命。 1.A 细节题。根据文章第一段2、3句Many people on the island had a disease called beri-beri. He was going there to try and find a cure.可知他去Java.,是为了寻找一种疾病的治疗方法,帮助当地人治愈这种疾病。故A正确。 2.D 细节题。根据第二段第二句He raised some chickens. He didn’t eat them, but made experiments on them.可知他养鸡是为了做实验。故D正确。 3.B 细节题。根据文章最后一段Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat.

He was going there to try and find a cure.可知他去Java.,是为了寻找一种疾病的治疗方法。故A正确。 考点:考查科学知识类阅读

Decision-thinking is not unlike poker—it often matters not only what you think, but also what others think you think and what you think they think you think. The mental process is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.

The great mathematician John von Neumann was one of the founders of game theory. In particular , he showed that all games fall into two classes : there are what he called games of perfect information , games like chess where the players can’t hide anything or play tricks : they don’t win by chance , but by means of logic and skills . Then there are games of “imperfect information”, like poker, in which it is impossible to know in advance that one course of action is better than another.

One mistaken idea about business is that it can be treated as a game of “perfect information”. Quite the reverse, business, polities, life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors, which would even puzzle the best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

1.The subject discussed in this text is __________.

A. the process of reaching decisions

B. the difference between poker and chess.

C. the secret of making good business plans

D. the value of information in winning games

2.An important factor in a game of imperfect information is __________.

A. rules   B. luck    C. time    D. ideas

3.Which of the following can be used in place of “Quite the reverse ” in Paragraph 3 ?

A. Quite right.   B. True enough.

C. Most unlikely.  D. Just the opposite.

4.In the writer’s opinion, when making business decisions one should _________.

A. put perfect information before imperfect information

B. accept the existence of unknown factors

C. regard business as a game of chess

D. mix known and unknown factors

根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Of the many unpleasant emotions we can experience, fear may top the list.    1. . Fear can also keep us from pursuing the things in life that really matter -- like following our dreams, and developing important relationships. I have some ideas, though, of how to be free from fear.

Experience fear.

I used to be very afraid of speaking in front of people. I would get sweaty palms and my stomach would be so tied up that I wouldn't be able to eat. However, each time I spoke, I noticed afterwards that it wasn't that bad. Things I fear are never as bad in reality as I make them out in my mind.    2.  .

Create space.

The first and most important step to being fearless is to create some space between ourselves and the emotion of fear. This isn't accomplished by ignoring the fear, or trying to talk ourselves out of it.    3.  . In fact, a recent research shows that by simply admitting the emotion we actually begin to reverse the "fight or flight(逃避)" response in the body.

Control the breath and feel the fear.

Once we acknowledge the presence of fear, the second step is to control the breathing so that it becomes slower and gentler. We try to make the breath just a little bit longer, and feel how fear manifests(展现) in the body.    4.  .

With practice, we can create enough space between us and the emotion of fear so that we're able to replace a fearful thought with a positive one.    5.  . For instance, before I get up to speak in front of a group of people, I imagine that the audience is positively impressed by what I say and that I manage to complete the speech successfully.

A. Space is created only when we can honestly acknowledge that fear exists.

B. We can imagine a positive outcome for whatever we're about to do.

C. Fear, if left uncontrolled, can even destroy our life.

D. So one way to get rid of fear is to simply push ourselves to do things that we fear.

E. When we can see a positive outcome in our mind, fear no longer holds us back.

F. But fear is more than just physically unpleasant.

G. As we pay attention to the physical symptoms of fear, we can see fear objectively.
