1、Unit20 lesson1 Grammar 课时：2 年级：高二班级： 姓名： 学习小组： 日期： Step 1一般将来时用法说明1. 基本用法及表示方法一般将来时的基本用法是表示单纯的将来事实，由“will / shall + 动词原形”构成：We shall have a lot of rain next month.下个月将下很多雨。2. 表示将来时间的常见方法英语中除了“will /shall+动词原形”表示将来时态外，还可以有以下多种方法：(1) 用“be going to+动词原形”表示。主要表示打算和预测：We are not going to stay there long.
2、 我们不准备在那里久待。(表打算)Im afraid theyre going to lose the game. 恐怕他们会赛输。(表预测)Look, its going to rain. 瞧，要下雨了。(表预见) 【注】be going to 后接动词go和come时，通常直接改用其进行时态：Where is he going to go? / Where is he going? 他打算到哪里去？(2) 用“be to+动词原形”表示。主要表示按计划或安排即将要发生的动作；有时也表示命令、禁止或可能性：He is to leave for Beijing tomorrow. 他决定明天去
3、北京。(3) 用“be about to+动词原形”表示。主要表示即将要发生的事：He is about to leave. 他即将要离开。Sit down, everyone. The film is about to start. 大家坐好，电影马上就要开始了。【注】该结构通常不与具体的时间状语连用：误：He is about to leave soon tomorrow.另外，该结构在美国英语中还可表示“打算”(主要用于否定句)：Im not about to lend him any more money. 我不打算再借给他任何钱。(4)用现在进行时(即be现在分词)表示。主要表示按计
4、划或安排要发生的事：The students are leaving on Sunday. 学生们星期日出发。【注】该用法有时表示即将发生的动作：Im leaving. 我走了。(5) 用一般现在时表示。表示按规定或时间表预计要发生的事：The train leaves at 7:25 this evening. 火车今晚7:25分开。【注】1. 在表示时间、条件等的状语从句以及某些名词性从句、定语从句等中，也用一般现在时表示将来意义。2. There be结构的一般将来时易出错 例：There _ a basketball match this afternoon. (B) A is goi
5、ng 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. Step 2将来进行时的用法 将来进行时表示将来某段时间正在进行的动作或所处的状态。如： Ill be having dinner at seven oclock. 七点钟我将正在吃饭。 This time next wee
6、k Ill be lying on the beach. 下星期这个时候我就会躺在沙滩上了。 在口语中将来进行时可用于表示安排要做的事。如：Ill be seeing you in the morning. 我明早来找你。 Step 3将来完成时的用法 将来完成时表示将来某个时间之前已经发生或完成的动作。如：By the time we phone they11 have left already. 我们打电话时他们可能已经走了。Ill have been teaching for thirty years this winter. 到今年冬天我就已任教30年了。【自主检测】1 _you _a
