如题所述
1. 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.
2. 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.
当be sure to 用于祈使句时,表"务必,切望"解.
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.
