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.

Im 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;beginbeginning 开始; swimswimming 游泳;runrunning跑步; putputting放;letletting让;getgetting得到四)以ie结尾的变ie为y再加ing。如:tie-tying系 die-dying死 lie-lying 位于现在进行时态专项练习一、 写出下列动词的现在分词形式stay _do _listen _forget _refuse _close _travel _die _work _spend _look _ make _put _sit _run _tie _take _give _ride _please _win _begin _open _lie _二、 用所给动词的适当形式填空1.
