高中英语问题

I can hardly imagine the great trouble they will have to take ___ their war-striken country.
A. rebuilding B. rebuild C. to rebuild D. rebuilt
答案是哪个？为什么？

Answer 1

C
take great trouble to do sth 是一个固定短语，意思是“不辞劳苦地做某事”“费力做某事”
本句they will have to take to rebuild their war-striken country是定语从句，修饰the great trouble ，引导词that省略，
即
I can hardly imagine the great trouble。
they will have to take (great trouble) to rebuild their war-striken country.
原句大意“我无法想象他们将不得不费很大气力来重建遭战争蹂躏的家园。”

又如：
We must thank her for taking all that trouble.我们要感谢她费神了。
Thank you for the great trouble you have taken to help me.
谢谢你费了很大气力来帮我。
You might have taken the trouble to tell us that the bridge was down!你是早该费一下神告诉我们桥已经放下来的！

have trouble 后面确实用in doing，但此处是take trouble,后面用to do.

Answer 2

A. take great troule in doing sth
