Question

.
I'm lucky enough to find the knife ____I lost yesterday .
A.which B.what C like D.as
答案给的是D 请问A为什么不对?可以理解成我幸运的找到了昨天丢了的小刀呀?

Answer 1

估计是答案有误或题目有误.
1. 如果原题无错,则答案为A.
关系代词which代替先行词the knife,并在定语从句中充当lost的宾语.
2. 如果原题为：I'm lucky enough to find the (same) knife ____I lost yesterday.
1）此时正确答案为D.
因为相关语法规定：如果先行词被as/so/the same/such等修饰时,关系代词必须选用as.
同样,关系代词as代替并相当于先行词the knife,且在定语从句中充当从句谓语动词lost的宾语.
2）如果答案为that,也可以.
注意两者区别如下：
I'm lucky enough to find the same knife as I lost yesterday.
我足够幸运地找到了和我昨天丢掉的小刀一模一样的小刀.
I'm lucky enough to find the same knife that I lost yesterday.
我足够幸运地找到了我昨天丢掉的那把小刀.
