第三课时SectionA(GrammarFocus~3b)一般现在时与现在进行时的比较※一般现在时强调动作的经常性和反复性,实际上是一种无时间限制的动作,而现在进行时强调动作的暂时性。eg:HelivesinBeijing.他住在北京。HeisstayinginBeijingnow.他目前待在北京。※一般现在时着重说明事实和特征;而现在进行时可以表示某种感情色彩。eg:Shealwayshelpsothers.(说明事实)Sheisalwayshelpingothers.(表示赞赏)※表示感觉或状态的动词一般不用现在进行时,而用一般现在时,表示现在的感觉或状态。eg:Hehasabikenow.现在他有一辆自行车。询问天气的句型和描述天气的形容词的构成1.询问天气的句型How'stheweather…?或What'stheweatherlike…?意为“……天气如何?”,用来询问天气情况。常用“It's+描述天气的形容词或现在分词”来回答。eg:—How'stheweatherinsummerinWuhan?/What'stheweatherlikeinsummerinWuhan?武汉夏天的天气怎么样?—It'sveryhot.很炎热。2.描述天气的形容词的构成我们在本单元中学到的与天气有关的名词主要有“rain(雨,雨水)”、“snow(雪)”、“wind(风)”、“cloud(云)”,以后还将学到“fog(雾)”。一般在它们后面加上字母“y”,以重读闭音节结尾的词,双写后面的辅音字母再加“y”后可转变为形容词。具体如下:rain(雨,降雨)——rainy(有雨的,多雨的)snow(雪)——snowy(有雪的,多雪的)wind(风)——windy(有风的,多风的)cloud(云)——cloudy(多云的,天阴的)fog(雾)——foggy(有雾的,多雾的)sun(太阳)——sunny(阳光充足的)一、用所给词的适当形式填空。1.Wecan'tgooutnow.It's_________(rain)sohard.2.It's_________(wind)butit'sveryhot(热).3.Look!They_________________(study)intheclassroom.4.Mybrotheroften___________(watch)footballonTV.5.Don'ttalk.Myfather_____________(sleep).6.—What'sTomdoingrightnow?—He__________soccer.He______soccereverySaturday.(play)rainingwindyarestudyingwatchesissleepingisplayingplays二、从A、B、C三个选项中,选择正确选项完成句子或对话。7.—What'stheweatherliketoday?—It's____.A.rainB.snowC.sunny8.—WhatisRickdoing?—He____foratest.A.studyB.isstudyingC.studies9.—Doyouoften____athome,Mr.Black?—Yes,Ido.A.cookB.cookingC.cooks10.—____itgoing?—It'sterrible.A.How'sB.What'sC.When's11.Gobacktoyourseat,butdon'tbelate____.A.nowB.againC.alsoCBAAB三、按要求完成下列句子,每空一词。12.Itiswindytoday.(对画线部分提问)_______the_______today?13.Davidplaysbasketballwithhiscousineveryday.(用rightnow替换everyday改写句子)David___________________withhiscousinrightnow.14.JeffandKevinarecleaning_the_classroom.(对画线部分提问)_________JeffandKevin_______?15.Ginaisplayingcomputergamesin_her_room.(对画线部分提问)_________Ginaplayingcomputergames?16.HowistheweatherinLondontoday?(改为同义句)_______theweather_____inLondontoday?How'sweatherisplayingbasketballWhataredoingWhereisWhat'slike
