________ in the company for three years,Mark has become experienced in business negotiations.
A) Having worked
B) Have been working
C) Have worked
D) Worked
为什么选A?
A) Having worked
B) Have been working
C) Have worked
D) Worked
为什么选A?
我用排除法给你解析下,首先是D,动词开头做一个句子的是没有的,除非前面有主语,C也是,B的话有个working ,但它这里用的是被动语态,与题意是不符合的,mark是人,做工作是他自己做的,而不是被做的,到最后,A,这里having.是做伴随状语,意思是随着他在公司工作了3年,表示一段时间他做了什么事
