Performing better under pressure

What is the most stressful thing in school? It is probably exams.小題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.小題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.
小題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.小題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.小題5:.    So,it turns out that practice really makes perfect.
根據(jù)短文內(nèi)容,從下面五個(gè)選項(xiàng)中選出能填入文中空缺處的最佳選項(xiàng),使短文意思通順、內(nèi)容完整,并在答題卡上將該項(xiàng)涂黑。
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.

小題1:B
小題2:E
小題3:D
小題4:A
小題5:C

試題分析: 本文提到在學(xué)校中給人壓力最大的就是考試,分析原因在于大腦中多巴胺的平衡能力起著重要作用,但也不要忽視熟能生巧這個(gè)原則會(huì)讓你減輕壓力。
小題1:B 根據(jù)上文提到What is the most stressful thing in school? It is probably exams.在學(xué)校最有壓力的事情是什么呢?可能是考試。所以緊接講考試會(huì)把我們處于壓力之下,故選B項(xiàng)。
小題2:E 根據(jù)上文提到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.多巴胺是身體中一種化學(xué)元素,向大腦發(fā)出信號(hào),他有很多重要的功能,影響記憶,注意力和如何學(xué)習(xí)。所以選E項(xiàng)當(dāng)他在我們身體中平衡時(shí),我們大腦才能更好的工作。
小題3:D 根據(jù)下方提到If you become stressed,your brain will start to overload (起負(fù)荷) on dopamine如果你感到壓力時(shí),你的大腦會(huì)開(kāi)始起多巴胺起負(fù)荷作用,所以選D。考試中會(huì)發(fā)生什么樣的狀況?
小題4:A 根據(jù)上文提到The quicker you are able to go back to a balance of dopamine,the quicker you can concentrate.你身體迅速恢復(fù)多巴胺的平衡能力越快,你越能集中注意力。所以選A 他能幫助你在考試中更好的表現(xiàn)。
小題5:C 根據(jù)下方提到So,it turns out that practice really makes perfect因此,他證明熟能生巧,所以選C 研究發(fā)現(xiàn)你練習(xí)的越多,你的壓力越小。

In the past twenty years, riding bicycles has become more and more popular among people of all ages. (1) Bicycles have long played an important part in the lives of American young people.But today an even greater number of adults cycle along roadsides and bicycle paths.These new riders are often trying to become fit or lose weight. They have found that bicycling is a pleasant way to stay healthy.
This is certainly good for health. But it has also brought some problems. With all these added people on the road, bicycle safety has become a matter of real importance.
Bicycle safety is mostly a matter of common sense. People should ride only on bicycle paths where they will not be badly hurt. There are also a number of rules that riders should follow,especially when riding on streets or highways. Bicyclists should never ride against the traffic,nor should they carry other people on their bicycles. They are also supposed to ride in single line on busy streets and to walk bicycles across the busy intersections(交叉路口).(2)By following these rules, bicycle riders will___ _____ stay healthy_____ ______be safe.
In one recent year, the National Safety Council reported that 34 thousand bicycle riders were hurt in highway accidents. In the same year,another six hundred riders were killed. Since the introduction of crash helmets(頭盔)in 1980,the number of injuries(傷者)and deaths from bicycling accidents had gone down. Today, more and more riders realize the dangers of bicycling. They are wearing helmets and paying closer attention to cycling rules.

Dear Mary :
Thank you for your last letter. I’m happy to know that you will spend your holiday in Hawaii this summer .You said you wanted to know something about Hawaii.
Hawaii has always been a magic name to people who like travelling because of the scenery .People from all over the world dream of seeing the beautiful islands. It’s always one of their dreams to watch the sun going down. At weekends , my family and I often watch the sunset at the seaside. It’s really exciting.
Hawaii is a fun place to go. Long long ago, the first people went to Hawaii in a small boat . They found the place quite beautiful. But it was difficult for travelers to go to Hawaii at that time. And there were no big hotels like the ones today. Now things have changed. Lots of nice big hotels have been built in recent years. However, the nice view in Hawaii hasn’t changed much. In the morning , many tourists often take a walk along the water in. At night , they get together to hold parties, chatting and dancing.
Now , you see Hawaii is really a good place to visit. I’m looking forward to seeing you soon.
Yours
Kate
