IV. 阅读下列短文，在空白处填写1个适当的单词或括号内单词的正确形式。

A

Tom: Hi, Mr.Smith. 　21　 you give me a hand?

Mr. Smith: Of course. You needn’t hesitate to ask me for help. What’s the matter with you?

Tom: My mum is always complaining about my going back home late after school.

Mr. Smith: What do you usually do after school?

Tom: I usually go to the playground to play basketball. But I know that I 　22　 go home first.

Mr. Smith: Why don’t you go home directly?

Tom: My mother usually says, “Every student shall do their homework first after school, and that is a rule for all of you students.” You see, if I did my homework first now, I couldn’t have a rest and relax. I am so tired.

Mr. Smith: Both you and your mum are reasonable. As a mother, she believes that you 　23　 never work too hard, while you think you need some time to have a rest. Does your mother know what you think?

Tom: No. Even if I had told her before, she wouldn’t have understood it.

Mr. Smith: I don’t think so. I think you should tell your mother what you think and she would understand you. Besides, you had better not hide your feelings from your mother and you 　24　 as well learn to communicate with her.

Tom: Thank you for your advice. It is high time I 　25　 （talk）with her.

Mr. Smith: I can’t agree more.

B

My deskmate, Mary, treats me as if she 　26　 （be）my sister. She is nice but fat. If she were not so fat, she would look like a super model. Last year, a doctor advised that she 　27　 （eat）more vegetables and fruits. He also made a suggestion that she（should）work out regularly. Besides, he insisted that she（should）walk to school. If she had followed the doctor’s advice, she would not be so fat now. In other words, if the doctor had persuaded her to do so, she would not have become overweight. This morning, Mary’s mother bought her a new dress. It was really nice. But after she tried it on, she couldn’t help shouting, “If only I 　28　 （be）a little thinner! How I wish I 　29　 （not eat）so much junk food before!” Were I Mary, I would make a weight loss plan. If I became overweight in the future, I would do sports every day. Now it is high time she changed her lifestyle. Without a healthy lifestyle, she wouldn’t be able to lose weight. I would rather she 　30　 swimming with me, but she insists that water sports are not suitable for her. So it is necessary that she should walk to school.
