Performing better under pressure

What is the most stressful thing in school? It is probably exams．【小题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 （信号） in the brain．It has many important roles：affecting memory，attention and how we learn．【小题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．
【小题3】． If you become stressed，your brain will start to overload （起负荷） 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．【小题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．【小题5】． So，it turns out that practice really makes perfect．
