When he— the door ,he found his keys were nowhere.A wound open B opend C had opend D was to open

问题描述:

When he— the door ,he found his keys were nowhere.
A wound open B opend C had opend D was to open

当他将要打开门时 他发现他到处都找不到钥匙 此句为过去将来时

A:当他想要开门时 ,他发现他的钥匙找不到了。选B则是当他打开门,他的钥匙找不到了

答案:C


主句he found his keys were nowhere是一般过去时。
从句when he HAD OPEND the door用过去完成时!

如果还是不懂,不记得复合句时态的用法没有关系的。
你就好好想想这两个句子动作发生的先后顺序。很容易的。

先开门才能找钥匙啊!!!!亲!


不懂可追问哟!XD

D was to open打算开门。
题上说了他发现他的钥匙不见了。因此,门没有开。

选D 要去开门的时候,发现钥匙不见了.
B错,因为意思成了:打开门的时候.而没有钥匙,是不能做出开门这一动作的.
请及时采纳,多谢!

主将从现 选d

When he— the door 是在found his keys 之前 所以应该是过去的过去 而不是一般过去
