发布时间:2016-02-29  编辑:查字典英语网小编

  be sure/ make sure

  Ⅰ. be sure 指某人对某事或对某种情况有把握,常译为:确信;make sure 指务必、务请、确保将某事弄清楚。如:

  ① I am sure that he is honest. 我相信他是诚实的。

  ② I have made sure that he is honest. 我已了解清楚他是诚实的。

  Ⅱ. 二者后面均可接of 或about 引出的短语。如:

  ① I am sure of success = I am sure that I will succeed. 我深信会成功。

  ② Will you make sure of his return? = Will you make sure that he returned?

  请你查明他是否真的回来了。好吗?

  Ⅲ. make sure 后面的that 从句一般不用或很少用将来时;

  be sure 后面的that从句则可用将来时。如:

  ① Make sure that you come here before five. 你一定要在5点前来。

  ② I am sure that he will come. 我相信他一定会来的。

  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;而be sure 则不受限制。如:

  ① to come to party on time. 一定要准时来参加晚会。

  ② He is sure to call you up. 他准会给你打电话的。
