Question

Performing better under pressure

What is the most stressful thing in school? It is probably exams．    1.   But some students succeed under pressure，while others struggle．So，why do some students perform better under stress?

It all comes down to dopamine （多巴胺）． Dopamine is a chemical in our body that sends signals （信號(hào)） in the brain．It has many important roles：affecting memory，attention and how we learn．    2.

Our brains control dopamine in two ways．It either takes out dopamine quickly，or gradually．Exam success can be linked to how fast dopamine goes back to a balance，according to new research from the University of Missouri，reported Yahoo．.

3. If you become stressed，your brain will start to overload （起負(fù)荷） on dopamine．It is like a cup overflowing with water．The quicker you are able to go back to a balance of dopamine，the quicker you can concentrate． 4.

Researchers found that，during a test，people who slowly got back to a balance of dopamine scored 8 percent lower． That’s me difference between a good mark and a bad mark．

But don't fear，there is good news for every student． 5. So，it turns out that practice really makes perfect．

A．This will help you perform better on a test．

B．Exams can put us under a lot of pressure．

C．The study also found that the more practice you get，the less stressed you’ll be．

D．What happens when we take an exam?

E．Our brains work best when there is a balance of dopamine—not too much or too little．

【解析】

試題分析：這篇文章主要講了多巴胺是一種給大腦發(fā)送信號(hào)的化學(xué)物質(zhì)，如果你變得緊張,你的大腦就會(huì)開始超負(fù)荷多巴胺，事實(shí)證明,實(shí)踐真的能生巧。

1.細(xì)節(jié)理解題。根據(jù)It is probably exam.可能是因?yàn)榭荚嚢桑?/span>可知選B。

2.細(xì)節(jié)理解題。根據(jù)Dopamine is a chemical in our body that sends signals in the brain多巴胺是一種給大腦發(fā)送信號(hào)的化學(xué)物質(zhì)�？芍獞�(yīng)選E。

3.細(xì)節(jié)理解題。根據(jù)If you become stressed，your brain will start to overload （起負(fù)荷） on dopamine．如果你變得緊張,你的大腦就會(huì)開始超負(fù)荷多巴胺。故選D。

4.細(xì)節(jié)理解題。根據(jù)The quicker you are able to go back to a balance of dopamine，the quicker you can concentrate．你能越快回到多巴胺平衡, 就可以集中越快。可知故選A。

5.歸納理解題。通過So，it turns out that practice really makes perfect．所以,事實(shí)證明,實(shí)踐真的能生巧。故選C。
