1、Alvin 英语语法强化练习现在进行时1. 定义：现在进行时表示正在发生或进行的动作。结构：be (am, is, are)+动词现在分词形式 （简写： be +动词-ing） A、肯定句主语be (am, is, are)+现在分词，如： I am reading English.我正在读英语。He is writing.他正在写字。 B、一般疑问句 Be(Am, Is, Are)+主语现在分词? 如：Are you singing?你正在唱歌吗？C、否定句主语be (am, is, are)+not+现在分词I am not doing my homework.我不在做作业。 2.关键词：
2、(1) now 、at the moment 此时此刻（四年级才会学到） (2) 句前有提示词 look 、listen 3.动词-ing 的构成规则 （1）一般情况下，直接加 ing，如：cook-cooking （2）以不发音的 e 结尾，去 e 加 ing，如：make-making, taste-tasting （3）如果末尾是一个元音字母和一个辅音字母，双写末尾的辅音字母，再加ing，如：run-running, stop-stopping （4） 以 ie 结尾的动词，先把 ie 变成 y 再加-ing。 lie- lying tie -tying die-dying 注意： se
3、e-seeing draw-drawing listen-listening 还有两个在网上看到的口诀，比较有帮助；1. 现在分词构成口诀 现在分词很好记，动词后缀-ing。 直接加、去 e 加、双写加。 还有一点要注意 ie 要用 y 来替。 2. 现在进行时用法口诀 主语在前 be 在后，现在分词跟着走，其他成分不可丢。 变一般很简单，把 be 提到句子前，否定句也不难，be 后要把 not 添。还有一点要注意，动作提问 doing 替。 Alvin 英语语法强化练习现在进行时态练习题一、 将下列动词变成 ing 形式help_ come_ swim_ eat _ give_ find _
