【简明语法】20.2 比较and和or

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 1 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.
