  初二英语重点句型和短语知识点总结

  have fun doing sth.

  【句型介绍】 意为”做某事有乐趣”,其中have fun 相当于enjoy oneself,表示过得愉快。

  1. 英语中的集体名词,如family, class, team等作主语时,若作为一个整体看,其后的谓语动词用单数;若强调其组成成员,谓语动词用复数。如:

  My family is a happy one. 我家是个幸福的家庭。

  在比较级中,要注意than后面人称代词的格。

  1)当句子中的谓语动词是不及物动词时,than后面的代词用主格还是宾格,在意思上通常没有区别。如:

  He runs faster than I / me. 他跑得比我快。

  But I don't know what to do.

  【句型介绍】 疑问词 + 不定式可作主语、宾语或表语。

  I don't know how to get her help. 我不知道怎样才能得到她的帮助。

  Where to buy this kind of seed is unknown to me. 我不知道去哪儿购买这种种子。

  My question is when to leave for Tokyo. 我的问题是什么时候去东京。

  1.由that引导,由于that没有任何意义,也不充当任何句子成分。因此that在非正式文体中可以省略。这类宾语从句通常表达一种陈述意义。

  e.g.He told me (that) he would go to Wuhan.

  Tom says (that) he must study hard.

  She told me (that) she was a student.

  (1)如果由and连接两个并列的宾语从句时,第二个that则不能省略。

  e.g.She said she liked English very much and that she didn’t like math at all.

  (2)常接that引导的宾语从句的谓语动词有:believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish等。

  2.由连接代词或连接副词who, whose, what, which, when, where, how, why引导,含有“谁、什么、哪个、什么时候、什么地方、怎样、为什么”等特殊疑问意义。

  e.g.Do you know who they’re talking about?

  Can you tell me what they’re looking for?

  I don’t know where she has gone.

  I wonder how she can find us.

  She didn’t tell me where her hometown was.

  3.由从属连词whether和if引导,含有“是否,能否,对否,有否”等一般疑问意义。

  e.g.She asked me if I could help her.

  Jim wanted to know whether I had taken his English book.

  Please tell me whether you can come or not.

  在这类宾语从句中要注意两点:

  (1)if引导宾语从句和状语从句的区别

  if引导宾语从句时意为“是否”,从句中该用什么时态就应用什么时态。

  if引导条件状语从句时意为“假如”,从句中应用一般现在时代替一般将来时。

  e.g.She wanted to know if you were a teacher.

  I don’t know if the letter is yours.

  They’ll go boating if it is fine tomorrow.

  I’ll give it to her if she comes next week.

  (2)if引导宾语从句时多数情况下可以与whether互换,但如果要突出“究竟是……还是不……”这层意思时,通常用whether,并在后面的加上“or not”,即一般要选择whether构成whether…or not的结构。

  e.g.Please find out whether the money is his or not.

  Let me know whether you can come or not.

  I want to know whether you can help me or not.
