发布时间:2016-2-1 编辑:互联网 手机版

 ○3 只能用which的情况:

  a. 关系代词前有介词。 This is the house in which we lived last year .

  b. 先行词本身是that 。 The clock is that which I bought yesterday .

  c. 非限制性定语从句。 His English , which used to be very poor, is now excellent .

  ○4 定语从句在句中作定语,所以在使用时,相当于现在分词短语,过去分词短语,动词不定式短语,介词短语作后置定语的句子。

  a.I bought a book that was written by Lu Xun . = I bought a book written by Lu Xun .

  b.Tell the children who are playing basketball not to do that . = Tell the children playing basketball not to do that .

  c.The house that stands at the corner was built in 1987 . = The house standing at the corner was built in 1987 .

  d.We have nothing that we should fear . = We have nothing to fear .

  e.The book that is on the table is expensive . = The book on the table is expensive .

  ○5 引导词when, where和why可用相应的表示时间(in, on, at, during等)、地点(in, on, at等)和原因(for)的介词+which 表达为介宾结构。

  a.I still remember the day when I met her for the first time . ---- I still remember the day on which I met her for the first time .

  b.That is the place where I went when I was a child . ----- That is the place to which I went when I was a child .

  c.May I know the reason why you are late ? ----- May I know the reason for which you are late ?

  ○6 在定语从句中,不能再出现指示先行词的指示代词。

  I just can't find the book which/that she lent it to me .(×)---- I just can't find the book which/that she lent to me .(√)

  ○7 注意下面的变化:

  a. This is the house(不作lived的宾语) where we lived last year .

  This is the house(作lived in的宾语) which/that we lived in last year .

  b. This is the day (不作left的宾语)when we left for Shenzhen .

  This is the day (作spent的宾语)which/that we spent in Shenzhen .

  ○8 限制性定语从句和非限制性定语从句的区别:

  a. 限制性定语从句:是句中不可缺少的组成部分,没有从句,先行词意思不明确,主句也不完整,从句主句不用逗号分开。

  b. 非限制性定语从句:是主句先行词的补充说明,没有从句并不影响主句意思的明确或完整,这种定语从句一般用逗号和主句分开,在非限制性定语从句中,一般不用that。

  ◎ Last Sunday they reached Dalian, where a meeting was to be held .

  ◎ She has two brothers, who are both doctors .

  Ⅲ There be 句型

  1. 英语"There + be + (not)"结构表示"有(没有)某人或某物"时,there 是无词义的引导词,be是谓语动词,它后面的名词是主语,两者再数上必须一致。句末往往有表示地点或时间的状语。

  2. 肯定句:There +(助动词或情态动词)+be 主语+地点(时间)状语。

  There is a pen on the table . / There will be a football match tomorrow .

  3. 否定句:There + be(助动词或情态动词)+not(any)(或+no)+ 主语…。

  There are not fairies in the world . / There wasn't a underground in Shanghai before ./ There won't be a football match tomorrow .

  4. 一般疑问句:Be + there +(any) +主语… ? / 助动词或情态动词 + there +be +(any) + 主语… ?

  Is there anything I can do for you ? / Will there be cloud tomorrow ?

  5. 特殊疑问句:疑问词(+名词)+be +there + 状语 ?

  How many weeks are there in a year ? / What is there on the desk ? / Where will there be a football match tomorrow ?

  6. 如果there +be 之后是并列主语,应根据离be 最近的名词来选择be的形式。

  There is a apple and two pears on the table . / There are two pears and a apple on the table .

  7. 含有引导词there 的句子用seem to be , happen to be , used to be 或live 等作谓语的结构。

  There happened to be an old friend of mine in the shop . / There used to be a temple here
