【非谓语】求语法讲解.
We were greatly encourage by the news of our team( )another gold medal.
A.to have won
D.having won
为什么是having won?不是have won?伴随状么?

非常简单.因为是动名词结构 of our team having won- - - ==of our team's having won .由介词of 决定的.又如:I am afaid of Mary / Mary's going there alone.so i will go with her anyway.
那介词后面一般不可以加不定式,除了这一个------ He was ABOUT to leave when she arrived.

by是介词,介词后面必须跟动名词,而having won 就是动名词,是动名词的完成式。

相当于of our team's having won another gold medal
介词后接所有格+-ing形式,属宾语,所以可以用“通格+-ing形式”替换。
介词后不能接to do
又如:
He apologized for his wife's being late.
=He apologized for his wife being lat...
