be sure of 对某事确信，后一般加名词或者
be sure that 后一般跟句子追问
be sure that 后一般跟句子追问
意思上呢
追答A:be sure of/about + 名词，代词，动名词 意为确信，对…有把握
表示对客观事物有肯定的认识和判断,主语必须是人。
e.g. As Jordan joined our team, we are sure of winning the game this time.
另外我们还要注意一些别的表达：
① be sure to … 一定，肯定
后接不定式往往表示局外人的推测，评论，主语不一定是人。
e.g. It's sure to rain tomorrow.
比较：
a. He is sure to live to ninety. 他肯定可以活到九十岁。
b. He is sure of living to ninety. 他自信可以活到九十岁。
② Be sure to 用于祈使句时，"务必，切望"解。
③ be sure 接that从句时，意为：认为…一定会，主语必须是人，连词that可以省略，be sure 后面还可以接由whether, where, when 或 who 等引导的名词性从句，这时，主句通常是否定形式。E.g.
我不能肯定今晚是否有空。
I am not sure whether I will be free or not tonight.
