certain of

一群中的某些 some particular members of a group of people

for certain

无疑地,确定地 without doubt

make certain

弄清楚 inquire in order to be sure about sth

make certain of

采取行动以便确有把握做其他事 do sth in order to be sure of (doing) sth else

(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。
