Is this college _____ they went to last year?
A.that B.which C.the one D.the one what
这题为何选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
如此就非常明显是选 the one 了——the one 是先行词,其后的关系代词that/which因为是用作宾语(用作代词 to 的宾语),被省略了。
注意不可以选 D,由于 what 不可以用作关系代词,不可以引导定语从句。
