(4)be sure 与be certain
be certain意思是确信,有把握,用法与be sure同,即:
be certain + 不定式
be certain + of/about-phrase
be certain + that-clause
但sure强调主语的心理状态,指主语心中无疑或十分确信、有把握,着重于人的内心世界,故其主语只能是人,且不能用来形容事件。所以当主语是表示事件的名词、代词或it时,只能用certain. certain 着重说明有肯定的理由和证据使人相信或确信,强调内心世界之外的证据。e.g.
①it is certain to rain.天肯定会下雨。
②His information was by no means certain.他的消息-点也不可靠。
③ Its almost certain that the government will lose the next election.几乎可以肯定现政府会在下次选举中输掉。
④We are sure/certain of victory.我们确信自己会获胜。
(5)make sure表示查明,弄确实和(采取行动)确保,其用法是:
make sure + of-phrase
make sure + that-clause
① I think I locked the door,but Ill just go back and make sure of it/that I did.
我想我是锁了门,但我还是回去查看一下吧。
②They made sure of winning by scoring two goals in the last five minutes.
他们在最后五分钟进了两个球,确保了这场比赛的胜利。
2. Perhaps Ill go to that one。也许我会去听那个报告。
Maybe it was useful for some people.它(指报告)对一些人或许有益。
这两句都不表示可能性的句型。此外还有probably和possibly。注意它们的区别。
(1)maybe大概,或许,意思与perhaps很接近,多数地方可以换用,但不及perhaps正式,多用于口语,还可用于礼貌的建议或请求,多用于句首或句末,多用于美国。
(2)perhaps也许,可能,大概,可与maybe换用,但比maybe正式。perhaps还可用于建议,清求及温和的命令,英国用法。
(3)probably大概,很可能,所表示的可能性虽不是完全肯定,但比maybe,perhaps实现的可能性大多与动词连用。
(4)possibly可能地,也许,或许,较probably意味弱,在肯定句里表可能性很小,在否定、疑问句中与can,could连用,表示无沦如何也不,肯定句中与can,could连用,以加强语气,表示设法,竭力地。e.g.
