You may have heard of the popular saying, “Practice makes perfect.” But have you ever wondered whether it's really true? Does practice always make perfect?

Sometimes practice does make perfect. Take a math test for example. If you know you're going to have a math test in a week, you can keep doing math exercises before the test. If you get a full mark on your test, that's perfect and you can say the practice helped get you there.

However, in some other fields of life, practice doesn't always make perfect. It doesn't mean that practice is useless. Sometimes it just means that there's no such thing as "perfect in a certain field. For example, if you play sports or a musical instrument, there are no perfect games or perfect shows. It all depends on what you consider to be perfect."

Even if practice doesn't always make perfect, it almost always makes you better than you were before practicing. The more you practice something, the better you are at it.

1.The writer takes a math test for example to ________.

A.explain what is perfect B.encourage us to practice less

C.show practice can help us a lot D.make us believe nothing is perfect

2.Why doesn't practice make perfect sometimes?

A.Because practice is useless. B.Because there isn't a certain standard.

C.Because life is difficult for us. D.Because we can never get a full mark.

3.What does the writer talk about in the text?

A.Practice never makes perfect. B.It's easy and fun to be perfect.

C.How to practice for perfection? D.Does practice always make perfect?

What is the most stressful thing in school? It is probably exams. Exams can put us under a lot of pressure. But some students do better under pressure. while others do not. 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. Our brains work best when there is a balance of dopamine--not too much or too little.

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 an even balance, according to new research from the University of Missouri, reported Yahoo.

What happens when we take an exam? If you become stressed, your brain will start to overload on dopamine. It is like a cup overflowing with water. The quicker you are able to go back to an even balance of dopamine, the quicker you can concentrate, helping you perform better on a test.

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

But don’t fear, there is good news for every student. The study also found that the more practice you get, the less stress you’ll have.

So, it turns out that practice really does make perfect.

1.Dopamine is a chemical in our body that ______.

4.Some students do better under stress because ______.
