代词一致
代词一致是指句子中代词应在数、性、人称等方面彼此保持一致，
如：One must do one' s best to increase production.
Everybody talked at the tap of his/their voice.
If anyone calls, tell him I' 11 be back in a moment. (him也可用him or her代替)
在写作中，如果表示不定的人，可以用you, we, one等，需要注意的是：同一篇文章中，只用同一个不定代词，而且所有格要与其一致。
肯定与否定一致
下列形容词、副词、代词从肯定句变成否定句时，须作相应的变化:
肯定句 否定句
