be sure 怎么用
1)意思:
一定,必须
2)用法:
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.
It is sure to rain.天一定会下雨.
He is sure to have known about that.他准会知道那件事.
He told me I was sure to get a warm welcome.他告诉我,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 mother.务必代我问候你母亲.
Be sure not to do that again.一定不要再干那种事了.
