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。
He doesn't have brothers and sisters. 要用or，不能用and。

不能这样说，应该是he doesn't have brothers or sisters.
and用在肯定句中，and连接两个词，词性要一致。
eg：He has brothers and sisters.
or用在一般疑问句,否定句和选择疑问句中。
eg:He doesn't have brothers or sisters.
Does he have brothers or sisters.
What does he have brothers or sisters?
