adj.形容词
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-ingbe 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 sureI 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。 来源于拉丁语动词cernere, cert-决定

adj.形容词
certain的基本意思是“确信无疑的”或“毋庸置疑的”,即“肯定的,确信的”,在句中常用作表语。其后可接动词不定式,表示“相信某人会做某事”。 certain的另一个意思是“某一,某种”,在句中只能用作定语,常与不定冠词a连用,修饰单、复数名词或抽象名词,表示“因故而未加具体说明的人、物、地点、时间等”。 be certain用于祈使句,意思是“一定要设法办到…”。 It is/was certain that…表示说话人的看法，其中certain 不可用certainly或sure代替。在否定句中,多接以疑问词whether,what,how等引导的从句。 certain前不能用very或extremely修饰,如需强调可用absolutely或completely等词修饰。 短语动词make certain的意思是“弄确实,弄清楚”,其后可接of引起的动名词短语或that从句。 certain表示“某个，某些”时，作形容词或代词，如a certain friend of his或certain of his； certain作形容词表示“一些”时，常修饰抽象名词，如a certain hesitation，a certain coldness； 区别certain和sure：两者后面都可跟of，不定式或that从句。certain比sure语气来的更重。It is certain that…比It is sure that…更为普遍。 I am certain/sure of his honesty.I am certain/sure to see him tomorrow.certian of和certain to do表示不同的意思。He is certain to come tomorrow.他明天一定来。 He is certain of coming tomorrow.他相信他明天一定来。certain作形容词指“确定的”时，后面接的介词about可省略。 I am not certain about where he lives.我不太确定他住在哪里。for certain表示“肯定的，无疑的”，属于固定词组。
