sure跟surely做副词时区别在哪里?
sure跟surely做副词时区别在哪里?
Sure与certain是近义词,均作“一定的,确信的”等解。两者用法相似,多数情况下可换用,但有时不能换用。其用法区别大致如下: 一、 两者可换用的情况: 1. 跟不定式,可用人或物作主语。例如: It is sure/certain to rain。
He is sure/certain to come。 You’re sure/certain to be happy with them。 2.跟连接代/副词引起的不定式,常用人作主语。例如: I’m not sure/certain what to do。
He was not sure/certain when to start。 3.跟of或about引起的短语。sure后可跟of doing sth。 常用人作主语。例如: I’m not sure/certain of that。
Are you sure/certain about it? I’m sure of his coming。 He’s sure of winning。 注:sure to do sth。与sure of doing sth。
的区别:前者表示说话者认为“主语一定…”;后者表示“主语自认为一定…”。例如: He is sure to succeed。 (说话者认为“他”一定会成功。 He is sure of succeeding。 (“他”自己认为一定成功) 4.跟that引起的从句,常用人作主语。
例如: I’m sure/certain that he’ll come。 I was sure/certain (that) he had seen me。 I’m quite sure/certain I left the book on the table。
注:当sure或certain用于否定句时,其后跟whether或连接代/副词引起的从句,不跟that引起的从句。例如: I’m not sure/certain whether I’ve met him before。 I’m not sure/certain whether he will come。
I’m not sure/certain who he is。 I was not sure/certain what I ought to do。 I’m not sure/certain why he wants it。 以上几种情况中的sure与certain虽可换用,但隐含意思不同。
Sure表示主观的推测或感觉,所述事实并不一定如此;certain则指说话者有充分的理由或根据,肯定某事会发生。如下面两句中的certain均不可用sure替换。例如: I’m certain he wasn’t in the classroom。
I saw him in the library。 I’m certain than he will go the concert。 He told me so an hour ago。 5.与make连用构成短语,后跟从句,作“弄清楚;设法做到”解。
例如: Make sure/certain when the train leaves。 Have you made sure/certain that the train has already left? 6.与for连用构成短语,在句中作状语。
作“确实;毫无疑问”解。例如:I don’t know for sure/certain that he’s dead。 I cannot sau for sure/certain when he will come。 二、 两者不可换用的情况: 1. 在“It is…that结构中只能用certain,不能用sure。
例如: It is certain that he will come。 It was certain that our football team would win the game。 如是否定句,用whether,不同that。
例如: It is not certain whether he will come。 2. 在祈使句中通常用sure,不用certain。例如: Be sure to tell me all the news。 Be sure and come as soon as possible。
Be sure you don’t upset any of them。 3.作定语时,sure作“有把握的;肯定的;可靠的”解;certain作“某个;某些”解。例如: Put it in a sure place。 There was only one sure way to succeed。
A certain person called on me yesterday。 Certain students have failed in the exam。 4.Sure在美语中可用作副词作肯定答语,用以代替surely,相当于certainly,of course;而certain则不能用作副词。
例如: I wonder if I could use your phone。 Sure。 Go ahead。 Zhou Lan, can I have a look at your copy of China Daily? Sure, go ahead。
surely是sure的副词形式。

答:Isure是动词作谓语{I主语,Sure谓语}。Iamsure是形容词作表语{I是主语,am是连系动词,sure是表语}。这就是它们的区别。详情>>
