两道英语选择
1.There are nearly one hundred foreign students in our university,most of _______ are from America and Australia.
A.which B.them C.whom D.those
2.–Why do you look so upset?
–The electricity was cut off suddenly and my essay _______ unfinished since.
A.was left B.has left C.left D.has been left
1选C,2选D,不太明白为什么
第一题 C 两个句子之间用逗号,说明要么是并列句要么是主从句.四个答案没有并列连词,所以只能选择主从连接词.此句只能做成定语从句.引导词在从句里做介词宾语代替人用whom.
如果用b/d那么,句子前加个and就可以了.
There are nearly one hundred foreign students in our university, most of whom are from America and Australia.
There are nearly one hundred foreign students in our university, and most of _them are from America and Australia.
There are nearly one hundred foreign students in our university, and most of those are from America and Australia.
第二个句子因为有since引导到现在为止作文没有完成因为断电.所以用现在完成时态,作文做主语,用被动语态.所以答案是D
