A. whether
B. that
C. how
D. what
答案:
(答案→)A. whether
B. that
C. how
D. what
解析:doubt指对事物的真、假有怀疑。它是动词时在肯定句中常与if或whether搭配使用。在否定句及疑问句中可跟that从句。有时在<肯定句>中也能跟that从句,但其含义是恐怕...不会。
它是名词时nodoubt后接that从句或介词of。
Wehavenodoubtthatyouwillsucceed.
Wehavenodoubtofyoursuccess.
我们毫不怀疑你会成功。
Thereis(Itis误)nodoubtthatyouwillsucceed.
毫无疑问你会成功。
How和 what都有词意,这个句子里不缺少它们的意思,故排除CD,所以选A。
