        1. Mr. Zhang ________ as an engineer since he came to the computer company in 2008.

          A.works B.worked C.has worked D.had worked

          C

          解析試題分析:句意:自從張先生在2008年來到這個(gè)電腦公司,他就是一名工程師了。分析考查固定句型:主句(運(yùn)用現(xiàn)在完成時(shí))+since+從句(一般過去時(shí)),主語是單數(shù)第三人稱,因此助動(dòng)詞為has.故選C
          考點(diǎn):考查時(shí)態(tài)的用法。
