【题目】I never doubt________he is an honest man.________I doubt is________hell come on time this time.

AwhetherThatwhen

BthatWhatwhether

CwhetherWhatwhether

DthatWhywhether

【答案】B

【解析】句意:我从未怀疑过他是一个诚实的人。我所怀疑的是他这次是否会按时来。doubt作动词时,用于肯定句中,其后接由whether/if引导的宾语从句;用于否定句中,其后接由that引导的宾语从句。doubt后的表语从句常用whether引导,又因为主语从句“________I doubt”中所缺少的成分是宾语,故选B
