Is this college _____ they went to last year?
A.that B.which C.the one D.the one what
这题为什么选C?
为使问题简化,可把句子还原为陈述句如下:
This college is _____ they went to last year.
A.that B.which C.the one D.the one what
这样就很明显是选 the one 了——the one 是先行词,其后的关系代词that/which由于是用作宾语(用作代词 to 的宾语),被省略了。
注意不能选 D,因为 what 不能用作关系代词,不能引导定语从句。
