be sure和make sure的区别

Ⅰ. be sure 指某人对某事或对某种情况有把握，常译为：“确信”；\x0d\make sure 指“务必、务请、确保”将某事弄清楚。如：\x0d\① I am sure that he is honest. 我相信他是诚实的。\x0d\② I have made sure that he is honest. 我已了解清楚他是诚实的。\x0d\Ⅱ. 二者后面均可接of 或about 引出的短语。如：\x0d\① I am sure of success\x0d\= I am sure that I will succeed. 我深信会成功。\x0d\② Will you make sure of his return?\x0d\= Will you make sure that he returned? 请你查明他是否真的回来了。好吗？\x0d\Ⅲ. make sure 后面的that 从句一般不用或很少用将来时；\x0d\be sure 后面的that从句则可用将来时。如：\x0d\① Make sure that you come here before five. 你一定要在5点前来。\x0d\② I am sure that he will come. 我相信他一定会来的。\x0d\Ⅳ. 两者后面接不定式，均表示“一定要做某事”，但make sure 通常只用于祈使句；\x0d\而be sure 则不受限制。如：\x0d\① Make sure to come to party on time. 一定要准时来参加晚会。\x0d\② He is sure to call you up. 他准会给你打电话的。
