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。结构是:be(am,is,are)+动
词现在分词形式。(简写:be+动词-ing)
A、陈述句(肯定句)
主语+be(am,is,are)+现在分词,如:
IamreadingEnglish.我正在读英语。Heiswriting.他正在写字。
B、一般疑问句
Be(Am,Is,Are)+主语+现在分词,如:Areyousinging?你正在唱歌吗?
C、特殊疑问句
疑问词+be(am,is,are)+主语+现在分词
Whatareyoudoing?你正在干什么-Iamdoingmyhomework.我正在做作业。
2.标志词:(1)时间状语now、atthemoment
(2)句前有提示词look、listen、lookat…
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-lyingtie-tyingdie-dying
注意:e-eingdraw-drawinglisten-listening
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。
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。
