Unit4 Section A Grammar Focus-3c语言点精讲精练
I．语言点精讲
1. have to 的用法
have to意思是“必须、不得不”, 它侧重于
客观上的必要和外界的权威。
1) 结构：主语＋have to＋动词原形＋其他
(一般现在时, 主语是第三人称单数时，
用has to；句子是过去时，用had to。) 如：
We have to wear sneakers for gym class. 在体育课上, 我们必须穿运动鞋。
Tom has to practice the guitar every day. 汤姆每天必须练习弹吉它。
I had to get up at 5:00 am last Monday. 上周一, 我不得不早上5点起床。
2) 否定形式： 主语＋don’t have to＋动词原形＋其他(一般现在时，
主语是第三人称单数时，用doesn’t have to；句子是过去时，用
didn’t have to)
e.g. Nick doesn’t have to wear a uniform.尼克不必穿校服。
We didn’t have to do our homework at once. 我们不必马上完成作业。
3) 疑问句：Do (Does 或 Did)＋主语＋have to ＋动词原形＋其他
如: --Do you have to stay at home on weekends
--Yes, I do. / No, I don’t.
周末你必须待在家里吗？
是的, 我必须。/ 不, 我不必。
Did he have to go to bed by 11:00 last night 昨晚, 他不得不11点上床睡觉吗？
2. Don't fight.不要打架。
fight此处用作动词，意为“打架；战斗”。
e.g.: Stop fighting! The teacher is coming.别打了，老师来了。
【拓展】fight的常见搭配:
fight against sb.与某人搏斗/打仗/作战；fight (with sb.) about/over sth.（与某人）就某事争辩；fight for sth.努力争取，为……而斗争。
3. 2.Can we eat in the classroom 我们可以在教室里吃东西吗？
情态动词can在本句中表示请求，意为“可以”。其一般疑问句形式为“Can+主语+动词原形+其他 ”；肯定回答用“Yes, ... can.”，否定回答用“No, ... can't.”。
e.g.:—Can I use your bike 我可以用用你的自行车吗？
—Yes, you can.是的，你可以。
4. What else do you have to do
else “其它的”, 用来修饰something, anything ,
nothing等, 还可用来修饰疑问词 what, where, who等, else修饰疑问词或不定代词时,
应后置。例如:
Do you have anything else to do .
Who else did you see
5. hear, listen和sound用法
hear, listen和sound都有“听”的意思，
但三者是有区别的。
1) hear “听说“, 侧重于”听”的内容。例如:
I'm sorry to hear that you are ill. 听说你生病了, 我很难过。
I never heard such an interesting story. 我从来没听过这么有趣的一个故事。
2) listen“听”侧重于“听”这一动作。
如果后面跟要听的事物，应跟介词to再跟事物
Listen to me carefully. 认真听我说。
The children like to listen to music. 孩子们喜欢听音乐。
3) sound“听起来”, 它是系动词, 后面接形容词等。例如:
That sounds great. 那听起来真不错。
It sounds like fun. 听起来挺有趣。
