be


小窥 “be to do” 的用法 一般说来,“be to do”这个结构有两种语法意义,其一是连系动词 be to do 做表语,其二是 be to 是一个独立词汇单位,具有情态含义,可以把它叫做情态习语(modal idiom)。 一、be +动词不定式,不定式做表语,表示主语和表语在概念上是等同的。如: The problem is to find a solution. His plan is to clean the room. My wish is to be a doctor. 二、 to +动词不定式中的 be to 用作情态习语,这时的 be to do 表示: “计划”、 be “安排”、 “义务”、 “应该”、“可能”、“命运”等。(have to, ought to)。如: He is to have a holiday. (表示将来) The committee is to meet today. (表示计划、安排) You are to go to the hotel where rooms have already been booked for you. 1.表示“计划”、“安排”。(意思接近于 be going to)如: Their daughter is to get married soon. Who is to question him? It was the last film at the cinema,which was to close next day. After dinner they were to go to a movie.

2.表示“义务”、“应该” 。(意思接近于 should, must, ought to, have to)如: No one is to leave the building.谁也不得离开这楼房。 You are not to smoke in this room.=You are not supposed to smoke in this room. You are to be back by 10 o’clock.你必须十点以前回来。 3.用于“if…were to do”,表示虚拟语气。如: If it were to rain tomorrow, the sports meeting would be put off.如果明天下雨,运动会就会 延期。 4.was/ were to have done,表示“本打算”、“本计划”或“本应当”做的事而没有做成或没有发生。 如: I was to have seen him last Wednesday, but he didn’t come. We were to have been married last year. Exercises: 1.This film _____ this Sunday.
