每周一練：it的用法

It的用法

It的用法在高考中也是重現(xiàn)率較高的語(yǔ)言點(diǎn)，尤其是it用于強(qiáng)調(diào)句。其考查方式多通過(guò)“單項(xiàng)填空”進(jìn)行，偶爾也出現(xiàn)在“短文改錯(cuò)”和“完形填空”中。

一、要點(diǎn)點(diǎn)拔

1．代替上文中提到過(guò)的人或事物。指代人時(shí)，一般用于小孩或身份不十分明朗的人。

   1) －Who is the baby?　　　

      －It‘s my teacher’s son．

   2) －Who is that gentleman?

      －It's my friend Tom．He(不可用It) wants to see you．

2．用于表達(dá)天氣、環(huán)境、時(shí)間、距離、季節(jié)等。例如：

   1) It’s half an hour’s walk from here to our school．

   2) It‘s nice and warm here．

   3) But it's two o'clock now, and it's time for us to go to school．

3．用作形式主語(yǔ).it 沒有具體意義，而只是幫助把真正的主語(yǔ)移至句子后尾，使句子顯得平穩(wěn)一些，能借it 給移至句子后尾的主語(yǔ)有三種：一種由不定式表示，一種由動(dòng)名詞表示，一種由從句表示。
    1).It 替代真正的主語(yǔ)——動(dòng)詞不定式短語(yǔ).
               It is easier to say than to do .
                It is a good act to help the others.
    2).it 替代真正的主語(yǔ)——動(dòng)名詞短語(yǔ),以動(dòng)名詞短語(yǔ)做主語(yǔ)的句子，主要在以no good, no use,   no harm, dangerous, foolish 等詞作表語(yǔ)的句中.
             It’s no harm drinking running water in that area。
             It’s foolish talking like that.

    3).it 替代從句作主語(yǔ)，用從句做主語(yǔ)的帶it 的句子很多,常見的有下面幾類：
    ①It is a pity (a shame ,a fact ,a wonder ,a good thing, etc. ) that…
      It is a shame that he didn’t pass the exam.
    ②It is strange ( surprising, obvious ,true, good, possible, clear, etc. ) that…
      It was clear that they had no desire for peace.
    ③It seems (happened ,turned out, etc.)that…
      It seemed that things were not as they expected.
    ④It is said  ( decided ,expected ,etc)that …    
      It is said that the tickets have been sold out.

4.用作形式賓語(yǔ)。

當(dāng)復(fù)合賓語(yǔ)中的賓語(yǔ)是不定式,－ing短語(yǔ)或從句往往用it作形式賓語(yǔ),而將真正的賓語(yǔ)移至句末,句子重心后移。

   1) We find it difficult to learn English well in such a short time．

   2) We think it no use crying over spilt milk．

   3) We made it clear when and where we were going to have the meeting．
