I doubt all the people invited will come to attend the ceremony in such bad weather.
A. whether
B. that
C. how
D. what

(答案→)A. whetherB. thatC. howD. 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no doubt后接that从句或介词of。 We have no doubt that you will succeed. We have no doubt of your success. 我们毫不怀疑你会成功。 There is (It is 误) no doubt that you will succeed. 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。

谢谢解答
