Question

—How long have you ________?

—For a couple of years.

A.become a doctor B.met your best friend

C.kept this dictionary D.bought the bread maker

Answer

C

【解析】

句意：——你保存这本字典多久了？——有好几年了。

考查延续性动词和非延续性动词。become a doctor成为医生；met your best friend遇见你最好的朋友；kept this dictionary拥有这本字典；bought the bread maker买这台面包机。在现在完成时中，如果句子里含有How long或者for+一段时间，要用延续性动词，become、met和bought都是非延续性动词，故A、B和D都排除。故选C。
