B是正确答案,原因有两个:
1. A选项中有一个after,原句里面已经有一个介词for了;
2. A选项中I have looked此处的look 没有什么含义,表达不完整.
这句话应该理解为: 被我细心 照料很多年的机器仍旧很好地运转着.
第二道题应该选择C, 被动语态出现在动词不定式中做补语.
秘书问她的老板,是否在她回家之前还有什么要打印的东西.
the machine-,( )for many years,is still walking perfectly
the machine-,( )for many years,is still walking perfectly
A; after which i have looked
B;which i have looked after
为什么是选b不是a呢?
还有一题
the secretary asked her boss whether he had anything more-( )before she went back home?
A;to type B;typed C;to be typed D;has typed
为什么是选b呢?
A; after which i have looked
B;which i have looked after
