一般将来时教学课件.ppt

英语语法;一般将来时表示将要发生的动作或存在的状态以及计划、打算做某事。E.g. They will have a football match tomorrow. He will be thirty next week. She is going to buy a coat this afternoon. ;其结构有如下几种: (1)will + 动词原形(will可以用于任何人称) 。需要注意的是：当主语是第一人称时will可以换成shall,特别是在以I或we作主语的问句中,一般用shall。 E.g. Shall we go to the zoo? ;(2)be going to +动词原形。E.g. I am going to see a film next Saturday? (3)现在进行时也可表示将来。E.g. The bus is coming soon.;第一种结构的句式变化是: 变否定句在will后边加not。 变一般疑问句把will提前。 E.g. She will be back in three days. She will not be back in three days. Will She be back in three days? ;第二种结构的句式变化要在be上做文章:E.g. They are going to clean their classroom. They are not going to clean their classroom. Are they going to clean their classroom? ;其时间状语有如下几种: (1) this引导的短语。 如： this year (2) tomorrow及其相关短语。 如： tomorrow morning (3) next引导的短语。 如： next month (4) from now on ; in the future ; in an hour 等。; 做题时常见错误如下： 一、易忽视动词用原形形式。 例：1. He will is (be) at school next Monday. 2. He is going to does (do) his homework after school. 答案：1. be 2. do ;解析：第一题有的同学一看he做主语就用了is，忽视了will后应加动词原形。我们在写句子时，很容易把动词丢掉，“英语句子里，动词不能少”的 规律必须要牢记。第二题中to后加动词原形，而不是用单三人称。 ;二、be going to +动词原形与will+动词原形用法不清楚。 例：我正努力学习，准备参加英语考试。 I am studying hard and I will try for my English exams. 答案：I am studying hard and I am going to try for my English exams.; 解析：“be going to” 表示计划、打算要做某事。E.g. He is going to visit his friends. 还表示某种迹象表明会发生某事。E.g. Look at the clouds. It’s going to rain. 而“Will+动词原形 ”指对将来事物的预见、表示意愿、决心。E.g. I will wait for you until you come. 在单纯预测未来时，二者可以互换，但在此题中只能用be going to，而不能用 will。;三、There be结构的一般将来时易出错。 例：There_________ a basketball match this afternoon. (B) is going to be B. is going to have C. are going to be D. are going to have 答案：A;解析：There be结构的一般将来时既要符合There be结构，又要符合一般将来时。有的同学认为have当“有”讲，所以选了B，但There be结构就不成立了，此句中is是be going to中的，是由后边的单数名词决定的. ;四、be going to结构中易丢掉to。 例：I’m going _______(go) school by bike tomorrow. (C) to will go B. to g
