Students learn many subjects at school, like Chinese, English, math and physics. Some students think it’s hard to do well in math. They say it’s boring. Why do they say this? First, some math problems are so hard for them. They spend a lot of time on them, but they can’t work them out, so they lost heart(失去信心). Second, they are afraid( 害怕) to ask their teachers for help. They think the teachers will laugh at them. Third, they think math class is very tiring because they need to use their brain(大脑)to find out the answers all the time.
How can you do well in math? Here is some advice from a math teacher:
1. Listen to the teacher carefully in class and do some extra(额外的) exercises after class.
2. Ask the teacher for help if you don’t understand anything. Don’t be afraid.
