中考英语语法详解六:动词

  4.need作情态动词时,常用在否定和疑问句中,表示“需要;要”的意思。

  如:Need we finish the work now?现在我们需要完成这项工作吗?

  They needn ' t look after him. 他们不需要照顾他了。

  拓展延伸need还可以用作行为动词,可以用于各种句型。如:

  Does he need any help? 他需要帮助吗?

  The desk needs repairing. 这张桌子需要修理。

  5.shall 用于第一人称,表示说话人征求对方意见,过去式为should;will 用手第二人称的疑问句中,表示说话人向对方提出请求和建议,过去式为would。

  如:Shall I go shopping with you?'我可以同你去购物吗?

  I don't know what I should do next. 我不知道下一步该干什么。

  Would you please come a little earlier?请你来早一点好吗?

  6.情态动词had better的用法

  (1)had better 后接动词原形,表劝告、建议,意为“最好”。“You'd better… ”含有强制命令的语气,对长辈不宜使用。

  如:You'd better ask that policeman over there. 你最好问一下那边的那个警察。

  (2)慎用had better! 注意以下四条:

  ①had better表达的是说话者强硬性的建议,告诫别人(包括自己)如何做。 如:Granny, the hospital is not very near. We'd better catch a bus. 奶奶,医院不是很近。我们最好坐公共汽车。

  ②had better不用于礼貌的请求或征询,它隐含一种警告或威胁。 如:You ' d better finish the work today and bring it tomorrow. 你最好今天就把作业完成,明天带来。

  ③had better意思接近should,但它除了表示语气强硬以外,还表示马上要去做的事情,比should更紧迫。 如:You’d better see a doctor at once. 你最好马上去看医生。

  ④had better不含比较的意思,该结构表示“It would be good to… ”,而不是“It would be better to…”。

  二、系动词

  系动词有实际意义,但不能单独做谓语,必须与表语一起构成句子的谓语,说明主语的性质、状态或身份等。 它分为完全系动词和不完全系动词。

  1.完全系动词(be)可接名词、代词、形容词、副词、介词短语、非谓语动词短语、句子做表语。如: I'm a student. 我是个学生。(名词) He is fine. 他很好。(形容词) It is me. 是我。(代词) Are you there?你在那儿吗?(副词) She is at school. 她在学校读书。(介词短语) He is to come soon. 他过会儿该来了。(不定式) My job is teaching English. 我的工作是教英语。(动词的ing形式) My idea is that we will start now. 我的想法是我们现在就开始。(句子)

  2.不完全系动词 (get,turn,feel,smell,look,sound,taste)一般只接形容词做表语。如:When spring comes, it gets warmer and warmer.

  春天来了,天气变得越来越暖和了。 Food may go bad soon if it is not put into a fridge.

  食物如果不放进冰箱里就会很快变坏。 My brother became / turned a teacher after his graduation.

  我哥哥毕业后就当上了老师。(注意become和turn的用法区别)
