Question

【题目】--What happened to the young trees we planted last week?

--The trees _________ well, but I didn’t water them.

A. might grow B. must have grown

C. would have grown D. would grow

Answer 1

【答案】C

【解析】

试题分析：考查情态动词与虚拟语气。句意：--我们上周种的小树怎么了？--那些树可以长得很好，但是我没有给它们浇水。根据句意可知，答语前半部分省略了if虚拟条件句if I had watered them；与过去事实相反，if条件句用过去完成时，主句用would/could/might have done。must have done一定已经做了某事，表示肯定的推测，故选C。
