中考專項復習動詞時態(tài)

一般現(xiàn)在時一、謂語動詞的構成形式：主語+動詞原形/第三人稱單數(shù)形式（三單）+----.是動詞原形還是三單取決于主語，當主語是第三人稱單數(shù)（he,she,it）時,謂語動詞為三單，反之，則為動詞原形。如，Heplaysbasketballeveryday.Ihavenoodlesforbreakfast.動詞原形變單三記住六個字母：s,es,ies.具體說見下表類別說明例詞s一般情況下加sWork-worksstay–stayses以s,x,ch,sho,結尾的加eswatch-watchesfinish-finishesies以輔音字母加y結尾的變y為i加esstudy-studies2.

表示習慣性和經(jīng)常發(fā)生動作，如：1）Ioftengotobedat9∶３０2）Whatdoyouusuallydoonweekends?3)Myfatherusuallyrideshisbiketoschool.3.

表示普遍事實或客觀真理，如，1)Theearthmovesaroundthesun2)Theteachertoldusthelighttravelsfasterthanthesound.三、標志詞常與下列時間狀語連用：1）Always,usually,often,sometimes,hardly,never等。如，Theyusuallygotoschoolbybike.2）onceayear,twiceaweek,everyyear/day/week等。如，Hewritestohisfathertwiceamonth.四、句式特點變疑問句，否定句時，當謂語部分為系動詞be時，疑問句把be提前，否定句在be后加not.即：一般疑問句：Be+主語+---？否定句：主語+be+not+----如，1.

---Isthisyourbike?---Yes,itis.No,itisn’t.2.Theyarenotmyparents.當謂語是行為動詞時，要用助動詞do/does，可以總結為如下公式：一般疑問句：Do/Does+主語+動詞原形+---？如，DotheyliveinBeijing?Yes,theydo.No,theydon’t.Doeshewritetohisfathertwiceaweek?Yes,hedoes.No,hedoesn’t否定句：主語+don’t/doesn’t+動詞原形+---.Theydon’tusuallygotoschoolbybus.五、即時訓練
