小升初英語第二節(jié)-一般現(xiàn)在時

第四章動詞和時態(tài)第二節(jié)一般現(xiàn)在時

知識梳理一、一般現(xiàn)在時的用法一般現(xiàn)在時表示經(jīng)常性、規(guī)律性或習慣性的動作或狀態(tài)。含有always,often,usually,sometimes,seldom,never,every+時間詞等時間狀語的句子要用一般現(xiàn)在時。如果句子中的主語是第一、第二人稱或其他復數(shù)形式的名詞，動詞用原形；如果主語是第三人稱單數(shù)形式或其他表示單數(shù)概念的名詞，動詞用第三人稱單數(shù)形式。如：Wefinishourhomeworkontimeathomeeveryday.Healwaysgoestoschoolatabout7:00inthemorning.二、動詞第三人稱單數(shù)形式的變化規(guī)則

1.一般情況下，直接在動詞詞尾加s。如：read—reads,play—plays2.以s,x,o,sh,ch結尾的動詞，在詞尾加es。如：go—goes，wash—washes3.以輔音字母加y結尾的動詞，把y改為i再加es。如：study—studies，fly—flies4.特殊形式：have—has，be—is三、一般現(xiàn)在時的句型結構1.含有be動詞的句子(1)肯定句：主語+be動詞+其他.如：I'm14yearsoldthisyear.(2)否定句：主語+be動詞+not+其他.如：IamnotinGrade4thisyear.(3)一般疑問句：Be+主語+其他？如：AreyoufromAmerica2.含有第三人稱單數(shù)形式實義動詞的句子(1)肯定句：主語+實義動詞的三單形式+其他.如：MikeplayscomputergameseverySaturdayafternoon.(2)否定句：主語+doesnot(doesn't)+實義動詞（原形）+其他.如：Mikedoesn'tplaycomputergameseverySaturdayafternoon.(3)一般疑問句：Does+主語+實義動詞（原形）+其他？如：DoesMikeplaycomputergameseverySaturdayafternoon3.含有原形實義動詞的句子(1)肯定句：主語+實義動詞（原形）+其他.如：WestudyinNo.1PrimarySchool.(2)否定句：主語+donot(don't)+實義動詞（原形）+其他.如：Wedonot(don't)studyinNo.1PrimarySchool.(3)一般疑問句：Do+主語+實義動詞（原形）+其他？如：DoyoustudyinNo.1PrimarySchool考點精析考點1考查一般現(xiàn)在時的動詞形式【例1】用所給動詞的適當形式填空。1.He___________(get)upat7o'clockeveryday.2.Whattime_______he______hishomework(do)3.Thesun_____________(go)downtothewest.

解析:本題考查正確填寫動詞的形式。在做這類題的時候，要先判斷句子的時態(tài)。第1、2小題分別體現(xiàn)經(jīng)常性和習慣性，應該用一般現(xiàn)在時，而he是第三人稱，故動詞要用三單形式，助動詞用does;第3小題太陽西下是自然規(guī)律，用一般現(xiàn)在時。答案：1.gets2.does；do3.goes舉一反三1.寫出下列動詞的第三人稱單數(shù)形式。

3．Wegoswimminginsummer.(就畫線部分提問)

________________________________________解析:本題三個句子都是一般現(xiàn)在時，在變否定句或一般疑問句的時候，我們要考慮借助助動詞do或does。第1小題主語LucyandLily是復數(shù)名詞，否定句加don't,要注意的是usually在否定句中要置于助動詞之后，實義動詞之前，或者也可以用否定詞never來整句改寫；第2小題Mike是第三人稱的主語，要用Does開頭，其后的動詞要用原形；第3小題中的goswimming是動詞詞組，也就是“做什么”的問題，用“What…do”的形式提問,同時注意we要改成you。答案：1.LucyandLilydon'tusuallygohometogether./LucyandLilynevergohometogether.2．DoesMikeoftenreadEnglishinthemorning3.Whatdoyoudoinsummer舉一反三按要求改寫下列句子。1.Doyoulikeplayingbasketball(作肯定回答)_____________________________________2.Mybrotherhasmanybooks.(改為否定句)_____________________________________3.Helivesinthevillagenearthemountain.(改為一般疑問句)_____________________________________4.NancycomesfromtheUSA.(就畫線部分提問)_____________________________________Yes，Ido.WheredoesNancycomefrom？Doesheliveinthevillagenearthemountain？Mybrotherdoesn'thavemanybooks.過關檢測一、寫出下列動詞的第三人稱單數(shù)形式。1.sit______2.swim______3.go______4.make______5.run______6.write______7.cry______8.study_______9.watch_______10.wash______11.say_____12.play______sitsswimsgoesmakesrunswritescriesstudieswatcheswashessaysplays二、單項填空。()1.He____toschoolfromMondaytoFriday.A.goB.goesC.going()2.Theearth____aroundthesun.A.movingB.movesC.moved()3.MissLi____music.A.teachesourB.teachesusC.teachour()4.____Linda____backatseveneverydayA.Is；comingB.Does；comesC.Does；comeBBBC()5.Lilydoesn't____amusiclessonintheafternoon.A.haveB.hasC.having()6.BothTonyandPeter____inClassOne.A.isB.doC.are()7.What____yourmotheroften____onSundaysA.is;doing B.does;doC.do;does()8.I____applesandshe____pears.A.like;like B.like;likesC.likes;likesACBB三、用所給單詞的適當形式填空。1.Myfather_____(be)athometoday.2.JaneandJoe_____(be)students.They_____(be)intheparknow.3._____(be)youabusdriver4.Weoften_____(play)ontheplayground.5.He_____(get)upatsixo'clockeveryday.6._____(do)you_____(brush)yourteetheverymorningisareareAreplaygetsDobrush7.What_____heusually_____afterschool(do)8.Danny_______(study)English,Chinese,maths,scienceandartatschool.9.Mikesometimes_____(go)totheparkwithhissister.doesdostudiesgoes10._____(do)Mike_____(read)Englisheveryday11.Howmanylessons_____(do)yourclassmates_____(have)onMonday12.Whattime_____hismother_____thehousework(do)Doesreaddohavedoesdo四、按要求改寫下列句子。1.Doyouoftenplayfootballafterschool(作肯定回答)__________________________________________2.Ihavesomebooks.(改為否定句)__________________________________________3.Alice'ssisterlikesplayingtabletennis.(改為否定句)___________________________________________Yes,I/wedo.Idon'thaveanybooks.Alice'ssisterdoesn'tlikeplayingtabletennis.
