1、现在进行时专题编稿：郭宇 审稿：贾巍 责编：夏芳莲 知识讲解一、构成be (am，is，are) + 现在分词 (动词+ ing)现在分词的构成规则：1. 一般情况：动词+ing work working go going2. 以不发音的-e 结尾： 去掉-e 再加-ing have having take taking3. 以重读闭音节结尾，结构是“辅元辅”的：双写词尾辅音字母再加-ing cut cutting run running二、形式肯定句：I am studying. 否定句：I am not studying. 疑问句：Am I studying? 简要回答：Yes，I am/
2、 No，I am not.注意：I am studying 可以缩写为 Im studying， 但是 Yes， I am. 一般不缩写为 Yes， Im. 因为 Im 后面一般都要接表语，而表语不能为空。三、用法1. 表示正在进行的动作例如：I am writing a letter. 我正在写一封信。They are learning English.他们正在学英语。Is it raining now? 现在下雨吗？The boys are helping their mother.孩子们正在给母亲帮忙。2. 表示最近一直在做的一件事（但说话时不一定在进行） 。例如：I am readin
3、g Harry Potter these days. 最近我在读哈里波特 。Are you working hard this term? 这学期你学习用功吗？He is writing a novel. 他正在写一本小说。3. 表示即将发生的动作。例如：We are going to watch a movie tonight.晚上我们将要去看电影。John is coming here next week and will stay here until May. 约翰下周将要来这并呆到五月份。4. 表示总是出现的事情（说话人可能对此有点烦） 。例如：He is always borrow
4、ing money from me.他老是找我借钱。We are constantly eating food. 我们一直在吃东西。四、辨析1. be going to 和 will 的区别be going to 和 will 都可以表示对将来的推测，但是表达的意义有不同：will 表示的是该推测更倾向于说话人的看法，而 be going to 则表示该推测基于现实证据、现象等。试比较：It will rain.It is going to rain.第一句可能是说话人的随意猜测，而第二句则可能是说话人看到天上有积雨云、蚂蚁搬家等现象后才发表的看法。但有时这两种表示法也没有什么区别。2. 一般
5、现在时和现在进行时的区别一般现在时表示经常性动作，现在进行时表示现在或现在阶段正在发生的动作。例如：He studies hard. 他（一贯）学习努力。He is studying hard. 他正在努力学习（可能马上要考试了） 。一般现在时表示现在发生的动作（强调动作的整体性） ，现在进行时表示眼前看的见的动作。例如：Boats pass under the bridge. 船从桥下通过。The boat is passing under the bridge.船正从桥下经过。一般现在时不带感情色彩，现在进行时带感情色彩（往往与 always， constantly 等副词连用） 。例如：
