题目

what he can do now is apologize to her in person
i like the person who are very diligent through step by step day by day ,
请问第一句对吧,第二句对吗,我要权威的答案,第一句估计对因为书本那样写的,理由是什么呢,

答案

第一句是对的
本来句子应该是 what he can do is (to) apologize to her in person.
但是 前面出现do了 或者出现do的形式 to 要去掉
第二句 不对
i like the person who is very diligent step by step day by day.
后面的两个介词短语 建议用一个就够了 两个感觉很奇怪 不自然
