Question

这个虚拟语气的题怎么做?

George would certainly have attended the proceedings -----
a)if he didn't get a flat tire
b)if the flat tire hadn't happened
c)had he not had a flat tire
d)had th tire not flattened
C没什么错误,可是B为什么不对?

Answer 1

此题 B选项不对的原因 是因为 the flat tire 是瘪胎这个物体；然后happen的主语如果指物的话 必须是一件事情！！ sth happened! sth必须指代 事情而不是 物体。 所以答案B
主语不对！但是时态的正确的 确实是对过去时的虚拟。

C选项 是正确的 只是省略了 if的 用法。

以上为该题的完全解析。

Answer 2

C
这是倒装句,原句为if he had not had a flat tire
觉得B意思不对吧.

Answer 3

B

主句是would have的话从句就用had done

从句中had提前只适用于从句放在主句之前时，所以c.d错

Answer 4

选D,完整 if he didn't get a flat tire ,George would certainly have attended the proceedings .
改过后就是
George would certainly have attended the proceedings,had the tire not flattened.
