[连词]比较and和or,第2张

1) 并列结构中,or通常用于否定句,and用于肯定句。

  2) 但有时and 也可用于否定句。请注意其不同特点:

  There is no air or water in the moon.

  There is no air and no water on the moon.

  在否定中并列结构用or 连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and.

  典型例题

  ——I don't like chicken ___ fish.

  ——I don't like chicken, ___ I like fish very much.

  A. and; and  B. and; but C. or; but D. or;and

  答案C.否定句中表并列用or, but 表转折。

  判断改错:(错)We will die without air and water.

  (错)We can't live without air or water.

  (对)We will die without air or water.

  (对)We can't live without air and water.
