题目
___ I know he needed money so badly ,i might have managed to help him
A unless
B When
C if
D Had
为什么答案是D?C为什么不行?
答案
的确是D正确.
这个虚拟条件句本来是有 If 的,但是省略了,然后助动词 had 也就提到句子前面来.
原句是：
If I had known he needed money so badly,I might have managed to help him.（对过去的虚拟,主句用might have done,从句用过去完成时 had known）【楼主,您的句子中的 know 应该是 konwn 】
意思是：如果当时我知道他很需要钱,我会设法帮助他的.
