初一现在进行时1.定义：表示现在或现阶段正在进行的动作。
常与now, these days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.2.基本结构：be动词(am ,is ,are) +动词的现在分词构成（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记忆口诀：现在进行主动宾，be +动词-ing要记清; 助动词(am, is ,are) 跟着主语变，am, is ,are + -ing;变疑问，助动词(am, is ,are) 后主语跟，变否定，助动词(am, is ,are) 后not 跟。
*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：一）一般在后加ing。
如：sing-singing, see-seeing, play-playing, go-going, do-doing,二）以不发音e的结尾的去掉e再加ing。
如：write-writing, have-having, come – coming 来；close - closing关；make – making 制造ride – riding 骑；write - writing 写;take - taking 拿走; have – having 有；三）以重读闭音节结尾且一个元音字母＋一个辅音字母（注意除开字母组合如show –showing, draw-drawing）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 购物；begin-beginning 开始forget-forgetting忘记；stop-stopping 停止travel-travelling 旅行；begin—beginning 开始; swim—swimming 游泳；run—running跑步; put—putting放；let—letting让；get—getting 得到|四）以ie结尾的变ie为y再加ing。
