英语求教,
15.Is the river _____ through the town very long?
A.flows B.that flows C.which flow D.the one flows
16.Is this college _____ they went to last year?
A.that B.which C.the one D.the one what
17.Is this the university _____ you visited last time?
A.that one B.which C.the one D.the one what

答案

1.B 主句：Is the river very long?that flows through the town 做定语从句,并且flow的主语是 river,用三单形式.
2.C 肯定句：This college is the one they went to last year.要填的是is 后的表语,they went to last year 是定语从句,连词省略掉了.
3.B 肯定句：This is the university which you visited last time.主句前面已经完整了,要填的就是连接词.
ps.1.像这种定语从句变成一般疑问句后,一个小技巧就是：变成肯定句或者找到主句就行了,因为要填的要么是表语,要么是连接词.如果主句不缺成分,那就是填连接词,如果主句缺成分,那就是填表语了.
2.比较一下2、3题,你会发现is后如果有两个名词性词语,要填的基本就是连接词了,如3题中的is后既有this,又有the university,要填的就是连接词了；而第2题中is后只有this college,要填的就是表语了.
