Is there doubt __________ international cooperation is key to ___________ with cybercrime.? A. whether;doing B.that ;dealing C.whether;dealing D.that;doing
解题思路: doubt用法;the key to doing sth
解题过程:
你好,高兴答疑:
答案:B 句意:国际合作是对付网络犯罪的关键有怀疑吗?
考点:doubt引导同位语从句;动名词。
1. doubt V. n.
doubt+宾语从句/同位语从句

(1)在否定句和疑问句中,doubt后面接that引导的宾语从句/同位语从句
。例如:

There is no doubt that he can finish the task on time. 毫无疑问,他能按时完成任务。

Do you doubt that she will succeed? 你怀疑她会成功吗?

(2)在肯定句中,doubt后面一般接whether或if引导的宾语从句。例如:

I doubt whether they can swim across the river. 我怀疑他们能否游过河去。

He doubts if she will keep her word. 他不敢肯定她是否会遵守诺言。

注意:在肯定句中,doubt后面也可以接that引导的宾语从句,但表示疑虑较大或“不相信”。
2.the key to doing sth做某事的关键。to是介词。do with 与deal with意思相同,但do是及物动词需接宾语,deal不及物。
如:What did you do with the matter?what是do的宾语。
愿你满意。
最终答案:略
