People appreciate ________ with him because he has a good sense of humor
A) to work
B) to have worked
C) working
D) having worked问题补充：
D) having worked 为什么错呢?
首先明确 appreciate 这个动词的基本用法是 appreciate doing sth
排除 A B
然后,明确句子的意思：他很幽默,所以人们很喜欢和他一起工作!
描述的是一般事实!用一般现在时 便可!选C
现在完成时：
用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在.
I have spent all of my money.(含义是:现在我没有钱花了.)
People appreciate having work with him .(含义是:现在人们不喜欢和他工作了）
