根据短文内容回答问题

    Students study lots of subjects at school, like Maths, Chinese, English and Music. Most students think

it’s hard to do well in Maths. They say it’s boring. Why do they say so? First, some Maths problems (问题) are so hard that they can’t work them out. They spend lots of time on them, but they can’t work

them out, so they lose heart (丧失信心). Second, they are afraid to ask their teachers for help. They

think the teachers will laugh at them. Third, they think Maths classes are very tiring (累人的) as they

need to use their brain (脑) to work out the answers to the questions.

    How can you do well in Maths? Here is some advice (建议) from a teacher:

    1. Listen to the teacher carefully in class and do extra (额外的) exercises after class.

    2. Ask your teachers for help if you don’t understand something. Don’t be afraid. Your teachers are

always glad to help you.

    3. Don’t forget to go over your lessons. Then you will be able to understand each question better.
