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） 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．

What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck.
If you arrange（排列） the 26 English letters in order and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…26 for z, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11="98," meaning 98 is its mark. Knowledge: 11+14+15+23+12+5+4+7+5="96," love:12+15+22+5="54," and luck: 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money? It can’t, either.
Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark.
Different attitudes lead to different courses of life. Most time people hope for a better life. It is possible that they will have a better life if they change their attitudes. When you change your manner and became friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive attitude towards failure, you’ll find it’s also rewarding（有益的）though it has caused you losses（損失）.
【小題1】The writer thinks  _________ is the most important thing in a person’s life.
