III.閱讀理解（共10小題，滿(mǎn)分為20分）
(A)
One of the most popular item (項(xiàng)) in the class newspaper is the advice column(專(zhuān)欄). Here are some of them and their answers ——
Q: I’m always late for school. I try not to be late, but I can’t help (避免) it. Please advise me what to do. Tommy.
A:
You are probably late for school because you don’t really like school.
My advice to you is to enjoy school more, and then you won’t be late so
often.
Q: I find it difficult to make friends. What do you think I should do? Sara.
A:
I can’t advise you until I know more about you. Your problem may be
that you are shy. On the other hand, it may be the opposite. You may be
too bold (大膽). Write and tell me more about yourself.
Q: I’m always at the bottom (末尾) of the class. What do you advise me to do? Molly.
A:
I advise you to concentrate (集中注意力) on improving your grades in one
subject at first. Next, try to improve your grades in another subject.
If you do this, by the end of the year you should be quite a long way up
from the bottom in all your subjects.
根據(jù)短文內(nèi)容，選擇最佳答案。
