   一、变否定句时相关词的改变


  肯定句变否定句时,除将谓语变为否定式外,句中其他词语也可能随之改变,如将some改为any,too和also改为either 1already 2改为yet 3,and改为or等:
  There are some birds in the tree. 树上有些鸟。
  →There aren’t any birds in the tree. 树上没有鸟。
  He likes the girl, too. 他也喜欢这个女孩。
  →He doesn’t like the girl, either. 他也不喜欢这个女孩。
  We have already seen 4 the film. 我们已看过这部电影。
  →We have not seen the film yet. 我们没有看这部电影。
  He likes singing and dancing. 他喜欢唱歌和跳舞。
  →He doesn’t like singing or dancing. 他不喜欢唱歌也不喜欢跳舞。
  二、不变谓语动词而变其他词语
  有时将肯定句变为否定句时,不改变谓语而改变其他词语:
  Both of us went there. 我们两人都去了那儿。
  →Neither of us went there. 我们两人都没去那儿。
  Both Jim and Mary can sing this song. 吉姆和玛丽都会唱这首歌。
  →Neither Jim nor 5 Mary can sing this song. 吉姆和玛丽都不会唱这首歌。
  All of the books are worth 6 reading 7. 所有这些书都值得读。
  →None 8 of the books are worth reading. 所有这些书都不值得读。
  三、部分否定与完全否定
  比较以下句子:
  All of us laughed when we heard it. 听到这事时我们都笑了。(肯定句)
  All of us didn’t laughed when we heard it. 听到这事时我们并未都笑。(部分否定)
  Not all of us laughed when we heard it. 听到这事时我们并未都笑。(部分否定)
  None of us laughed when we heard it. 听到这事时我们都没笑。(完全否定)
  【注】可能涉及部分否定的词语有both, all, always, every等,即not both表示“并非两者都”,not all 表示“并非所有的都”,not always 表示“并非总是”,not every表示“并非每个…都”。
