thereisnodoubtwhether和thereisnodoubtthat的区别?
2.doubt+宾语从句
(1)在否定句和疑问句中,doubt后面接that引导的宾语从句.例如:
Idon”tdoubtthathecanfinishthetaskontime.我相信他能按时完成任务.
Doyoudoubtthatshewillsucceed?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:
Idoubtwhethertheycanswimacrosstheriver.我怀疑他们能否游过河去.
Hedoubtsifshewillkeepherword.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”.
