比較and和or
1) 并列結(jié)構(gòu)中,or通常用于否定句,and用于肯定句。
2) 但有時(shí)and 也可用于否定句。請注意其不同特點(diǎn):
there is no air or water in the moon.
there is no air and no water on the moon.
在否定中并列結(jié)構(gòu)用or 連接,但含有兩個(gè)否定詞的句子實(shí)際被看作是肯定結(jié)構(gòu),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; but c. or; but d. or;and
答案c。否定句中表并列用or, but 表轉(zhuǎn)折。
判斷改錯(cuò):
(錯(cuò)) we will die without air and water.
(錯(cuò)) 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.
