Question

【题目】______ as chairman of Alibaba, Jack Ma is helping build a credit system for small businesses.

A.To resignB.ResignedC.ResigningD.Having resigned

Answer 1

【答案】D

【解析】

考查非谓语动词。句意:辞去阿里巴巴董事长之后，马云在帮助建立小企业的信用系统。根据句意可判断，分句部分无主语故resign需要用非谓语动词，又因为resign发生在is helping之前。所以需要用having done的形式做状语。故选D项。
