be sure的用法.doc

be_sure的用法对be sure的用法常感困惑不解,现将其主要用法归纳如下。
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besure about则侧重指主语对某具体事物的确信无疑。例如:
He is sure of 。
I'm sure of his 。
However,he went on to explain that he was not sure about two things—thegrammar and some of the ,他接着就解释说,他在语法和某些习惯用语方面都没多大把握。
If you are not sure about the situation in the world,you can read the newspaper every ,你可以每天看看报纸。
若后面要接反身代词,则只能用be sure of,即be sure of oneself,意为“有自信心”。例如:
Joan will sit for an important examination next week,but she is not sure of ,但她对自己没有十分把握。
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。例如:
It is sure to 。
He is sure to have known about 。
He told me I was sure to get a warm ,说我准会受到热情接待的。
然而be sure to do用在祈使句中,不是表示判断,而是表示对对方的要求,意为“务必要”,“一定要”。例如:
Be sure not to forget it!千万别忘记呀!
Be sure to send my regards to your 。
Be sure not to do that 。
sure+宾语从句,表示主句主语对宾语从句中涉及的事物所作出的判断,意为“确信某事一定会……”。例如:
I'm not sure whether I've met him 。
We are sure he will make great progress this 。
