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&
2、#160;you singing?你正在唱歌吗?C、否认句主语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:(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的构成规那么 1一般情况下,直接加ing,如:cook-co
3、oking 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: see-seeing
4、;draw-drawing listen-listening 还有两个在网上看到的口诀,比拟有帮助;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,否认句也不难,be后要把not添。还有一点要注意,动作提问doing替。 现在进行时态练习题一、 将以下动词变成ing形式help_&
