词义辨析

adj. (形容词)

be sure of, be sure to

• 这两个短语意思不同,前者表示自己的主观看法,是针对自己而言的,而后者是表示对他人〔物〕的估计,对别人〔别物〕而言的。例如:
• Fight no battle I am not sure of winning.
• 不打无把握之仗。
• They are sure to succeed.
• 他们一定能成功。

I am sure,I am certain

• I am certain比I am sure语气强,前者指“不容置疑的”“确实已成为事实的”,后者指很强的“愿望”“深信”，但是I am not certain与I am not sure意思相同。例如:
• I am certain that he has left—I saw him go out.
• 我肯定他已走了——我看见他出去了。
• I am sure that they'll win the game this time.
• 我肯定这次比赛他们一定赢。
• 我不能确定她是否过得幸福。
• I am not certain if she is happy.
• I am not sure if she is happy.

sure, certain, positive

• 这三个词都表示“肯定的”“确信的”,但所表示的程度有所不同。
• 1.certain强调有充分的根据,或自己直接所知道的事情的真相。
• 2.sure强调主观上怀有强烈的愿望或心里没有疑虑。例如:
• I'm sure we'll start on time.我想我们能及时出发。
• 3.positive比sure和certain更加肯定,强调对自己所说的话或所下的结论的正确性深信不疑,常常表现出过分的自信或主观武断。例如:
• I am positive that I saw this man before.我肯定我以前见过此人。
• As I can't be certain,I won't be positive.在我不肯定时,我不想武断。
• 4.名词性从句作主语时,一般不用sure,而用certain。

sure，certain，definite，positive

• 这些形容词均含“无疑的，确信的”之意。
• sure侧重主观上对某事确信无疑。
• certain与sure同义，但语气比sure强，着重指有确切理由或不容置疑的证据所支持的确信。
• definite指已毫无怀疑的余地。
• positive语气强烈，指对自己的看法或作的结论的正确性有不可动摇的信念。

常见错误

adj. (形容词)

1. 我确信他将会对这起事故负全部责任。

   误 I'm sure of that he will take sole responsibility for the accident.

   正 I'm sure that he will take sole responsibility for the accident.

   析 be sure of的宾语是that从句时,介词 of常省略。

2. 他一定已经从北京回来了。

   误 I am sure that he must have come back from Beijing.

   正 He must have come back from Beijing.

   析 must 用来表示讲话人肯定的推测,而 I am sure 也是讲话人用来表明自己的肯定的看法的。因此 must 和 I am sure 用在一起就语义重复,可把 I am sure 删去。

3. 这报告肯定是假的。

   误 It is sure the report is false.

   正 It is certain that the report is false.

   析 用it作形式主语代替后面的名词性从句时,不能用sure,只能用certain。

4. 我不能肯定他已死了。

   误 I don't know with sure that he's dead.

   正 I don't know for sure that he's dead.

   析 for sure表示“肯定地”,是习惯说法,介词for不能用with替代。

5. 请一定锁好房子。

   误 Please make sure that the house will be properly locked.

   正 Please make sure that the house is properly locked.

   析 make sure是动词短语,通常用于祈使句中,表示“肯定”“设法做到”,后面的从句中往往用一般现在时表示将来,强调某一愿望或要求一定要实现。

6. 我对那事很有把握。

   误 I am quite sure for it.

   正 I am quite sure of it.

   析 be sure of〔about〕 意为“对…有把握”“确信”,是句子的主语本身持有的态度,介词不可用for。

7. 只要日本人民坚持斗争,他们一定会赢得胜利。

   误 So long as the Japanese people keep on fighting they must win in the end.

   正 So long as the Japanese people keep on fighting they are sure to win in the end.

   析 must表示“命令”“义务”“责任”,或用以推测未知的事情,上面的句子表示将来肯定会取得某种结果,不可用 must,应用sure。
