動詞ing的變換與練習

1、動詞ing形式的用法及變化規(guī)則一.動詞ing形式的用法1. 正在進行時中,謂語動詞后加ing. 如:l'm playing football.2. 一些特殊表達.如：be good at doing sthenjoy doing sth.be busy doingfeel like doingtha nk you for doingdo some cook in g/clea nin g/read in g/shopp in g/wash ing go swimmi ng/fishi ng/shoppi ng/skati ng/boati ng二.動詞現(xiàn)在分詞由動詞原形在詞尾加 ing

2、構(gòu)成，其規(guī)則如下:1） 一般情況下直接加ingthink-thi nki ng study-study ing carry-carry ingsleep-sleep ingspeak-speak ingsay-say ing2）以不發(fā)音的字母e結(jié)尾的單詞，去掉字母e,再加ingwake-wak ingmake-maki ngcome-comingtake-takingleave-leav inghave-hav ing3）以重讀閉音節(jié)結(jié)尾，呈現(xiàn)輔，元，輔”結(jié)構(gòu)的動詞，先雙寫末尾的輔音字母，再力卩 ing 。初中學過的這類詞有：beg in，cut, get, hit, r un, set, s

3、it, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。 （visit 不是以重讀閉音節(jié) 結(jié)尾，不用雙寫）travel雖然重讀第一音節(jié)，詞尾音節(jié)不重讀，但是現(xiàn)在分詞仍要雙寫末尾輔音字母，然后再加ing，如：travel-travelling.初中階段此類詞只有這一個。4）以y結(jié)尾的動詞直接加ingcarrycarry ingenjoyenjoying5 ）以ie結(jié)尾的動詞，把ie改為y，再加ingdie-dyinglie-lyi ng要特別注意有些動詞沒有進行時態(tài)1、表示狀態(tài)、思想、感情和感覺的動詞，如：se

4、e, hear, love, know, want, hope, think等，沒有進行時態(tài)。2、當have/has作為“擁有”時，沒有進行時態(tài)，但表示“開會，吃飯，玩得咼興”等意思時，可以用進行時表達。1 am havi ng ma ny books.（這是錯誤的句子）I am hav ing a good time.（這才是正確的句子）一.寫出下列動詞的現(xiàn)在分詞形式workvisitplaystudydancehavetraveltakedropsingshopswimlie二選擇題練習1.
