英語語法之and和or的辨析
比較and和or
1) 並列結構中,or通常用於否定句,and用於肯定句。
2) 但有時and 也可用於否定句。請注意其不同特點:
There is no air or water in the moon.
There is no air and no water on the moon.
在否定中並列結構用or 連接,但含有兩個否定詞的句子實際被看作是肯定結構,因此要用and。
典型例題
---I don't like chicken ___ fish.
---I don't like chicken, ___ I like fish very much.
A. and; and B. and; butC. or; butD. or;and
答案C。否定句中表並列用or, but 錶轉折。
判斷改錯:
(錯) We will die without air and water.
(錯) We can't live without air or water.
(對) We will die without air or water.
(對) We can't live without air and water.
