Question

【题目】---How long did your English teacher teach at this school?

---Ah, she _________ at this school since she _________ Wuhan.

A. has taught; has come to B. has been teaching; came to

C. taught; came to D. has taught; has been to

Answer 1

【答案】B

【解析】

句意：——你的英语老师在这所学校教了多长时间？——啊，自从她来武汉以来，她一直在这所学校教书。考查动词时态辨析题。since自从/从…以来，后面可接时间段、时间段和从句，表示一段时间，多用与现在完成时结构的句子，其引导的时间状语从句则用一般过去时。she是单数第三人称，需借助has + done构成现在完成时。根据句意语境，可知她现在还在武汉教书，需用现在完成进行时，故选B。
