问题 I wouldn’t doubt ______ she would want to help us.
选项 A、whether
B、that
C、since
D、as
答案B
解析 “doubt+宾语从句”时，在否定句和疑问句中，doubt后面接that引导的宾语从句。例如：I don’t doubt that he can finish the task on time. (我相信他能按时完成任务。)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。)所以确答案为选项B。
