用it做形式主语 帮我改一个句子 在线等
He spent 4 hours in doing hie homework yesterday.
用it做形式主语 帮我改一个句子 在线等He spent 4 hours in doing hie homework yesterday.
It took him 4 hours to do his homework yesterday.
It cost him 4 hours doing his homework yesterday.
就是这样的 it + costs + somebody+ doing sth 这就是个句型
这个句子是过去式 所以还是用cost
LS说的take也是可以的
It took him 4 hours to do his homework yesterday.
或It spent him 4 hours doing his homework yesterday.
是It took him 4 hours to do his homework yesterday.
当句子主语为动词或从句时才使用形式主语。
It took him 4 hours to do his homework yesterday.
没有 it + spends + somebody+ doing sth 这个句型,只有 sb spends sometime (in) doing sth 和 sb spends sometime on sth 。
