题目内容
________human beings________animals can live without air.
- A.Not only,but also
- B.Both,and
- C.Either,or
- D.Neither,nor
D
分析:句意是“没有空气人类和动物都不能生存。”not only…but also…(不仅……而且……),both…and…(既……也……),是肯定概念;either…or…(或者……或者……)是选择概念;neither…nor…(既不……也不……,两者都不)是否定概念。此处根据句子的意思,应该用neither…nor….(延伸)neither…nor…是both…and…的反义词组。把含有both…and…的句子改为否定句时,不要把谓语动词改为否定形式,而是把both…and…改为neither…nor…,谓语保持肯定形式(句子是否定句)。和either…or…一样,neither…nor…连接主语时,谓语要和后面的主语保持一致,如:Bothhis father and his mother are doctors.否定句:Neither his father nor his mother is a doctor.
