英语句子："I like banana, ------ donot like apple"应该but还是and

but but but

but是转折,如I like bananas, but don't like apples.
and是连接上个句子,如I like bananas, and I like apples.

^-^后面那个句子是用否定词don't,doesn't就用but
没有否定词,和前一个句子的意思差不多就用and
^-^

but
用于转折

这句话是用BUT
but表示转折
典型例题
--- Would you like to come to dinner tonight?
--- I'd like to, ___ I'm too busy.
A. and B. so C. as D. but
答案D。but与前面形成转折，符合语意。而表并列的and， 结果的so，原因的as都不符合句意。
1) 并列结构中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。

but
因为前面是说喜欢，后面是说不喜欢，所以应该用转折but
如果是and就是并列，不同的意思就不能用and
如果是my grandpa likes reading newspaper he doesnot like watch TV.那也是用but
如果是my father likes swimming he likes watching football match.
那就是用and，变成my father likes swimming and he likes watching football match.
成为了并
