doubt+whether
答:这个与中文比较类似。doubt否定,后加that从句。如:I don't doubt that he can win the match doubt肯定,后加whether从句。如:I doubt whether he can come on time tomorrow.
答:从语法上说可以在doubt后面直接用 if/whether 引导的从句。曾经有人做过一个非正式调查,问英美人可不可以这么用。多数人未置可否,但表示自己会说 I doubt that...,或者 I doubt (that)...。因此,从习惯上说人们很少这么用,但你要这么用也不会有人认为你错。
答:例如:I doubt whether they can swimacross the river. 我怀疑他们能否游过河去。He doubts if she will keep herword. 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”。例如:We doubt that they can completethe work ahead of...
答:I doubt whether/if he can speak English.(肯定句)I do not doubt that he can speak English.(否定句)Do you doubt that he can speak English?(疑问句)而be sure的肯定疑问形式后接that从句,否定形式后接whrther/if形式 I am sure that he can do it well.(肯定句)Are you sure ...
答:I doubt whether they can swim across the river. 我怀疑他们能否游过河去。doubt的用法例句:1、There can be little doubt that he will offend again.毋庸置疑他还会再犯的。2、They have the usual quota of human weaknesses, no doubt.毫无疑问,他们身上也有人所共有的弱点。3、This new ...
答:vt.[后接宾语从句时,如主句为肯定句时用 if 或 whether 连接,如主句为否定句或疑问句时用 that 连接] 不信任,不相信,怀疑,疑惑:I never doubted you; I was sure you would bring me the money.我从不怀疑你的,我肯定你会给我带来这笔钱的。I doubt whether (或 if) he will want...
答:如:He had his doubts whether they would give him another chance to have a try.他不能肯定他 们是否会再给他一-次机会试一 试。There is some doubt whether their football team will win the match.他们的足球队会不会赢 得这场比赛还不能肯定。(2) doubt用在否定句中,后面接that引导...
答:而用doubt that时,后面要接的是 将要发生或已经发生的一个事实,表示我对这件事的怀疑。而且doubt that通常用在否定句里,表示“恐怕、不会”的意思。用于肯定句的话,还是doubt if/whether更符合习惯。I doubt if she will change her mind.意思是我怀疑她是不是真的会改变想法。I doubt that ...
答:doubt + weather 与 + if 都表示怀疑某事是否怎样,通常是不知道而产生疑惑。唯一的区别是weather后面习惯性的可以加or not.如:I doubt weather it gonna happen (or not).I doubt if it gonna happen. 这两句话是同一个意思。表示我们不知道这件事是否会发生。doubt + that + 从句 表示...
答:宾语从句,doubt后跟宾语,这里whether he will succeed做doubt的宾语,所以是宾语从句
