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。
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。
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。

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。
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。
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。

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。
