英语句子问题-求解

图中划绿线的句子：I have to look after him.
这里面有个情态动词：have to
情态动词跟动词原型，可这里接look(take的过去式）为什么？
注意了：虽然这是一道改错题但这个句子没错

Answer 1

I have to look after him
这句话没有错！这句话的中文意思是：我必须去照看她。
Iook after是“照顾;照料;料理;打理”的意思
have to后面一定接动词原形，所以是：have to look after……
look本身就是原形。的过去式和过去分词都是looked；现在分词是looking

再举几个look after的例句：

You must learn how to look after yourself.
你要学会调理自己。

I mean to look after my body.
我得多注意身体。

I work in a school so I don't have to worry about finding someone to look after my little boy
我在学校工作，所以不用为找人照顾我年幼的儿子而操心。

Answer 2

take 的过去式是 took, 这里的look after是个固定搭配，也是照顾的意思。

Answer 3

have to之后加动词原形，look after 照顾，其中look 就是动词原形，它并非take的过去式。
