my father likes apples, so likes my mother

Everyone has finish the homework except you and me

finish 改成finished 因为has finished是现在完成时，它的构成是have + 过去分词，finished是过去分词

my father likes apples, so does my mother.
原因是在表示某人也是时，应该用so+助动词（do/does)

look after it
原因是：动词与介词构成的词组在词义上相当于一个及物动词，宾语总是在介词后面，此题就是这个结构（after为介词）
例：
I don’t much care for television．我不很喜欢电视。（care for=like）

my father likes apples, so likes my mother 改为 My father likes apples,so does my mother.

Everyone has finish the homework except you and me 改为 Everyone has finished the homework except you and me.

I'll be away for a few days ,what should i do with the dog?
_let me help you look it after

改为I'll be away for a few days ,what should I do with the dog?
_let me help you look after it .

look it after 不对
after是介词应该把宾语放在介词之后

将 likes改为 does,我爸爸喜欢苹果,我妈妈也喜欢.

Everyone has finish the homework except you and me
