The foreigners have gone to the farm( )we worked last year.

问题描述:

The foreigners have gone to the farm( )we worked last year.
A.what b.where c.that d.on which
为什么选D不选B?C能选么
那请问B和D有什么区别么。

答案:DB
这是考察定语从句的用法,which关系代词指代前面的the farm,on which = on the farm.即:we worked 【on the farm】 last year,所以这里必须要加介词on.答案B where是关系副词,其实也是正确答案.
