2017届高考英语一轮复习方案精品课件：第8讲 Unit 2《Wish you were here》（牛津译林版必修3）

　　Boys and girls,

　　May I have your attention, please? I have an announcement to make.

　　Next Friday afternoon, from 3：00 to 5：00 pm, in the lecture hall on the third floor of the school library, the Student Union will hold a meeting to elect a new chairman. First, all the students who want to enter for the election will give a self－introduction, followed by a five－minute speech. And finally, the voting will be carried out. 阅读写作(八) │ 词句模板 Everybody is required to attend the meeting. Be sure not to be late or absent. By the way, remember to prepare an introduction of yourself as well as a short speech if you want to have a go.

　　That's all.

　　Thank you!

　　　while 作名词用，表示“一会儿”，如for a while。作连词可以引导时间状语、让步状语从句(意思是“虽然……但是……；尽管……但是……”)(多放于句首)和条件状语从句(意思是“只要”)。作并列连词用，意思为“而，然而”，侧重于前后的对比关系。而but侧重于转折。注意用心比较体会while与but在句中的用法。 while引导时间状语从句时其后的从句谓语动词只能是延续性动词，强调主从句的两个动词同时发生。【易混辨析】 while，when和as 三者都译为“当……的时候”，区别为：when后的从句谓语动词既可是延续性动词，也可是短暂性动词，而且还可作并列连词，译为“这时”。但以下句型一定用when作并列连词：句型A：be about to do...when... 正要做……这时(发生另一事) 句型B：was/were doing...when... 正在……这时(发生另一事) 句型C：had done...when... 刚要做……这时(发生另一事) 第8讲 │ 句型透视
