1. 定义:表示现在或现阶段正在进行的动作。常与now, these days. at the/this moment, It’s 3: 00.等时间状语连用,句首有 Look ! / Listen !等提示语。
I’m visiting my friends now. Look! He is sitting there.
Listen! She is singing
2.基本结构:be动词+动词的现在分词(即 动词-ing)
肯定句: be + doing 否定句: be + not doing
一般疑问句:Be动词提前到句子开头 +主语+doing
例句:
肯定句: I am working. He is working. They are working.
否定句:I am not working. He is not working. They are not working.
疑问句:Are you working? Is he working? Are they working?
回 答:Yes, I am . Yes, he is. Yes, they are.
No, I’m not. No, he isn’t. No, they aren’t.
注意:现在进行时的特殊用法:
1)现在进行时与always 连用时,往往含有赞扬、厌恶、责备等感情色彩。
如: He is always working hard.他总是非常努力地工作。(表示赞扬)
2)come, go, begin, start, leave 等动词常用现在进行时表示将要发生的动作。
She is leaving China tomorrow. I'm going to school.
3. 现在分词的变法规则:
当我们说某人正在做什么事时,动词要使用分词形式,不能用原形,构成如下:
1)一般在后加ing。如: sing-singing, see-seeing, play-playing, go-going, do-doing,
2)以不发音e的结尾的去掉e再加ing。如:write-writing, have-having, come – coming;close - closing关 ;make – making ;ride – riding 骑; write - writing; take - taking ; have – having ;
3)以重读闭音节结尾且一个元音字母+一个辅音字母,要双写最后的辅音字母再加ing。如:put-putting, run-running, get-getting, let-letting, begin-beginning; sit- sitting ;cut – cutting 切 ;shop-shopping;begin-beginning 开始 forget-forgetting忘记;stop-stopping 停止travel-travelling 旅行;begin—beginning 开始; swim—swimming;run—running; put—putting;let—letting让;get—getting
4)以ie结尾的变ie为y再加ing。如:tie-tying系 die-dying死 lie-lying
