Tense),一般现在时表示经常发生的、习惯性的动作或存在的状态。其时间状语为often、usually、always、sometimes等频率副词,on Saturdays、in the morning(afternoon/evening)、every day(week/year)等.,17,(1)表示事物或人物的特征、状态。,e.g.:天空是蓝色的,Theskyisblue.,玛丽的爸爸是一名英语老师,MarysfatherisanEnglishteacher.,(2)表示经常性或习惯性的动作。,e.g.:我每天六点起床。,Igetupatsixeveryday.,她每天都做运动,Sheplayssportseveryday.,(3)表示客观现实。,e.g.:桌子有四条腿,Thetablehasfourlegs.,我们班有50个学生。,Thereare50studentsinmyclass.,18,(4)表示客观真理,科学原理,自然现象,等客观事实或格言、谚语等。,太阳每天从东方升起。,Thesunrisesintheeasteveryday.,地球绕着太阳转。,Theearthgoesaroundthesun.,(5)表示平日的喜好。,Ilikebananas.,Wedontlikevegetables.,Helikesicecream.,Shedoesntlikestrawberries.,19,在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚。现归纳总结如下:,一、人称代词he,she,it是第三人称单数。,如:He likes watching TV.他喜欢看电视。,She has lunch at twelve.她十二点吃午餐。,二、单个人名、地名或称呼作主语;是第三人称单数。,如:Han Mei likes salsd .韩梅喜欢萨拉。,Beijing is in China.北京在中国。,Uncle Wang often plays volleyball.,王叔叔经常打排球。,三、单数可数名词或“this/that/the+单数可数名词”作 主语时,是第三人称单数。,如:This book is yours.这本书是你的。,That car is red.,The cat is Lucys.这只猫是露茜的。,20,四、不定代词someone,somebody,nobody,everything,something等及指示代词this,that作主语时,是第三人称单数。如:Everyone is here.大家到齐了。,This is a pen.这是一支钢笔。,五、不可数名词作主语时为第三人称单数。,如:The milk(牛奶)is in the glass.牛奶在玻璃杯里。The bread is very small.那面包很小。,六、当数字或字母作主语时,看作第三人称单数。,如:“6”is a lucky number.“6”是个吉利数字。,I is a letter.I是个字母。,21,二只有主语在第三人称单数时用动词的“三单形式”,其他人称用动词原形。,动词三单形式的变化规则:,(1)多数直接在动词词尾加-s,playplays likelikes ask-asks,work-works get-gets call-calls,(2)以字母,s,x,ch,sh,或o结尾的动词,在词尾直接加,-es.,watch-watcheswish-wishesdo-does go-goes,(3)以“辅音字母加-y”结尾的动词,要先变y为i再加-es,try-tries study-studiescry-criesfly-flies,不规则变化:,be-is have-has,22,三、一般现在时的句子转换:,(1)变一般疑问句:当句子中有be动词或情态动词时,则把be动 词或情态动词(can,could等)提到主语的前面,(口诀:一调二变三问号),(2),变否定句,:在be动词或情态动词后面直接加not变成否定句(be)后not莫忘记),例:陈述句:Sheismysister.,否定句Sheisnotmysister.,疑问句Issheyoursister?,陈述句:Icanplaysoccer.,否定句Icannot/cantplaysoccer,疑问句Canyouplaysoccer?,Yes,Ican./No,Icant.,23,注意:,对一般疑问句的回答:一般用什么问就用什么来回答。但以下例外:,Isthisapencil?Yes,itis./No,itisnt.,Isthatyourbackpack?Yes,itis./No,itisnt.,Aretheseyourparents?Yes,theyre./No,theyarent.,(3)当句子中没有be动词,也没有情态动词时,变一般疑问句时,在主语前加助动词do(I,we,you,以及复数),does(第三人称单数she,he,it等)变成问句;,(4)变否定句时,在主语后谓语动词前加助动词dont,doesnt变成否定句,,切记:助动词后的动词则还原成动词原形。,例:,陈述句:We get up(起床)at 7:00 every morning.疑问句Do you get up at 7:00 every morning?,否定句We dont get up at 7:00 every morning.,陈述句:She has a brother.,疑问句 Does she have a brother?,否定句 She doesnt have a
