besuretodosth与besureofdoingsth的区别

besuretodosth与besureofdoingsth的区别

be sure to do sth与be sure of doing sth的区别be sure to do sth:其主语既可以是人称主语,也可以是非人称主语.译为“肯定"、“一定”、“谅必"、“势必"等等。

例如:Tom is sure to help her。

汤姆肯定会帮她的。

We are sure to get a warm welcome。

我们一定会受到热烈欢迎的。

Be sure to keep your eyes open for it。

务必留心注意它。

It’s sure to b e fine tomorrow。

明天准会天晴。

This plan is sure to succeed.该计划势必成功。

be sure of doing sth: 其主语只能是人称主语,而不可能是非人称主语(除非指人格化的事物)。

译为“确信”、“自信”、“信得过”、“有把握”等等。

比如,可以说:I’m sure of knowing you well。

我确信对你十分了解。

Alan is sure of winning before the game。

比赛前,阿兰自信稳操胜券.但不可以说:*Such a book is sure of proving popular.(这样一种书确信事实能证明自己会广受欢迎。

)*The fish is sure of selling well。

(这种鱼自信能畅销。

)显然,“人”可以“自信”或“确信”,而“书或鱼等物”则不可能“自信”或“确信”。

这便是受限于“主语意向”的结果.以上情况,同样适用于be certain to do sth结构与be certain of doing sth结构。

比较下列两句:1)My father is sure to live to a hundred.2)My father is sure of living to a hundred。

be done to do sth的语法点

be done to do sth的语法点'bedonetodosth'是一个常用的英语结构,表示某个人或物被安排或强制执行某个行动。

betodosth的几种用法

betodosth的几种用法

例如:When are you to leave for home你什么时候回家She is to be married next month.她将于下个月结婚。

这种结构也可用于过去。

was / were to do sth. 表示曾经计划要做的事,但不表明计划是否被执行,或表示“命运(即命中注定要发生的事)”,而非计划;was / were to have done sth.表示未曾实现的计划。

语法 专题三

语法  专题三

专题三非谓语动词◆非谓语动词的考查要点1.动词不定式复习中应注意的几个问题(1)不定式作表语与“be+to do sth.”的异同。

不定式作表语说明主语的内容或性质。

My job is to teach English.(说明内容)be+to do sth.(表示按计划要做的事)He is to go abroad.(2)后接不定式作宾语的词语。

下列词语常接不定式作宾语:afford,promise,refuse,expect,hope,learn,offer,wish,want,fail,plan,agree,forget,like,prefer,decide,manage,try,arrange,determine,desire 等。

下列词语后可接“疑问词+不定式”:teach,decide,wonder,show,learn,forget,ask,find out,advise,discuss等。

(3)如何理解和使用不定式作宾补。

①动词(短语)see,watch,notice,hear,listen to,observe,feel,taste,smell,make,let,have等的宾补用动词原形,变被动时要加to,此时的不定式就是主语补足语。

①下列词语后常接不定式作定语:chance,wish,right,courage,need,promise,time,opportunity,way,the first,the second,the last,the only等。
