Question

make sure和be sure的区别是什么？

Answer 1

Ⅰ. be sure 指某人对某事或对某种情况有把握，常译为：“确信”；\x0d\x0amake sure 指“务必、务请、确保”将某事弄清楚。如：\x0d\x0a① I am sure that he is honest. 我相信他是诚实的。\x0d\x0a② I have made sure that he is honest. 我已了解清楚他是诚实的。\x0d\x0aⅡ. 二者后面均可接of 或about 引出的短语。如：\x0d\x0a① I am sure of success\x0d\x0a= I am sure that I will succeed. 我深信会成功。\x0d\x0a② Will you make sure of his return?\x0d\x0a= Will you make sure that he returned? 请你查明他是否真的回来了。好吗？\x0d\x0aⅢ. make sure 后面的that 从句一般不用或很少用将来时；\x0d\x0abe sure 后面的that从句则可用将来时。如：\x0d\x0a① Make sure that you come here before five. 你一定要在5点前来。\x0d\x0a② I am sure that he will come. 我相信他一定会来的。\x0d\x0aⅣ. 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\x0a而be sure 则不受限制。如：\x0d\x0a① Make sure to come to party on time. 一定要准时来参加晚会。\x0d\x0a② He is sure to call you up. 他准会给你打电话的。

Answer 2

make sure：意为“确保；查明”，其后可跟of 短语或that 从句。

例句：They scored another goal and made sure of victory.

他们又进了一球，从而锁定了胜局。

例句：We will do our best to make sure that you are safe here.

我们会尽最大努力确保你在这里的安全。

be sure：意为“确信；一定；切记”，其后可以跟about 短语、不定式或that从句。

：You can be sure about their interest in it.

你可以肯定他们对此很感兴趣。

be sure的用法：

be sure of/ about+动名词或名词，意为“确信......"；"对....有把握”。但在接名词时，be sure of侧重指主语对某抽象事物的确信无疑；而be sure about则侧重指主语对某具体事物的确信无疑。

be sure+不定式，表示说话人对句子主语作出的判断，认为句子主语“必定”、“必然会”、“准会”如何如何。
