Question

is this factory___ we visited last year? A. in which B.around that C.whom D.the one答案是D,为什么?

Answer 1

这是个定语从句的疑问句形式，陈述句形式为This factory is the one that we visited last year。由于the one指的是This factory，在定语从句we visited 中作visited的宾语，故可以省略引导词that，，故为This factory is the one we visited last year。变成疑问句形式便是答案D.希望可以帮到你，，

Answer 2

the one是先行词，后面省略that，改成陈述句=this factory is the one we visited last year。
比较：this is the factory which we visited last year

Answer 3

陈述句的形式：
This factory is the one (that) we visited last year.
所以应该填写the one that,而that在这里省略了。

Answer 4

这句理解是你可把它先看成陈述句，就容易理解了 This factory is the one。。。，the one后面的作为定语从句，意思是 这就是我们去年参观的那一家吗？

Answer 5

D 缺少先行词 补充一个 只能是the one 此句是定语从句 先行词在从句中做宾语，省去关系代词that /which
