(a) certain, some

这两者都有“某一,某些”的意思。

1.some侧重于表示对某人或某物一无所知; 而a certain则多用于对某人或某物知而不详或知而不言。

2.some可与or, or other, or another等笼统的词连用; a certain则可与姓氏连用。

3.some经常含有不在乎、不感兴趣、轻蔑,甚至不赞成、不喜欢的意思; (a) certain则一般不带或少带感情色彩。

4.a certain还可和抽象名词连用,暗示说话者该用什么词来表达心里的想法拿不太准,在许多情况下,那个选出来的词有点不达意、不寻常,用a certain有助于削弱该词的奇特程度。

be certain to-v, be certain of v-ing

be certain to- v 意思是“肯定会做某事”,指将要发生某事; be certain of v -ing意思是“觉得肯定要做某事”,指某人的自我看法。

He is certain to succeed.

他一定会成功。(是别人对他的估计)

He is certain of succeeding.

他有把握成功。(是他对自己的信心)

certain, positive, sure

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。

I am certain,I am sure

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，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。
