B是正確答案,原因有兩個：
1. A選項中有一個after,原句里面已經(jīng)有一個介詞for了；
2. A選項中I have looked此處的look 沒有什么含義,表達不完整.
這句話應(yīng)該理解為： 被我細(xì)心 照料很多年的機器仍舊很好地運轉(zhuǎn)著.
第二道題應(yīng)該選擇C, 被動語態(tài)出現(xiàn)在動詞不定式中做補語.
秘書問她的老板,是否在她回家之前還有什么要打印的東西.
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
為什么是選b不是a呢？
還有一題
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
為什么是選b呢？
A; after which i have looked
B;which i have looked after
為什么是選b不是a呢？
