  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.

v.死;死亡
  • Flowers will die without water.没有水,花就会枯死。
  • We shall die some day.我们总有一天要弃世而去。
