            带有“尾巴”的句子 (续二)

花篮
  在上一篇,我们见识了谓语是特例的反意问句。今天我们就再来见识一下主语是特例的情况,看看下面这三句话是不是有点不一样?

  There is a computer on your desk.
  This isn't your umbrella.
  Those are your books.

  想想能抓住狐狸的尾巴吗?有点难度吧?!我们以前说过,“尾巴”中的主语一定要用代词,那么这些句子的主语该变成什么样的呢?这就是我们现在所要讲的问题:主语形式是特例的情况。

  1. 当陈述句是there be句型时,“尾巴”中的主语还是用there。例如:
  There is little water in the bottle, is there?(注意这里含有little这个否定意义的词,所以尾巴就用肯定形式了。)

  2. 当主语是单数指示代词this, that时,“尾巴”中的主语用it。例如:
  That is your book, isn't it?
  而当主语是复数指示代词these, those时,“尾巴”中的主语用they。例如:
  These are good books, aren't they?

  3. 当陈述部分有everyone, someone, no one, anyone等表示人的不定代词作主语时,“尾巴”中的主语用单复数都可以。如:
  Everyone is here, isn't he/ aren't they?
  No one liked this film, did he/ did they?

  4. 当句子的主语是everything, anything, something, nothing表示事物的不定代词时,“尾巴”中的主语通常用单数形式。如:
  Everything is quiet, isn't it? Nothing has happened, has it?

  好啦,主语是特殊情况的反意疑问句,你掌握了吗?
