一般现在时讲义及练习题

一般现在时1．概念：一般现在时表示经常的、习惯性的动作或存在的状态一般现在时表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。可概括为①经常性或习惯性动作；②长期存在的特征或状态；③普遍真理、客观事实等。2．构成：一般现在时的构成主要有两种形式,一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。：（1）be型：句子的谓语动词只有be（am，is或are）：a．肯定句中，只出现be，如：Iamastudent．我是一名学生。b．否定句中，要在be后面加not，如：Sheisn'tateacher．她不是教师。c．一般疑问句，要将be放在句子开头（注意句首字母大写），句尾用问号，答语用Yes，主语+be．或No，主语+be+not．如：—Areyouready？—你准备好了吗？—Yes，Iam．—是的，我准备好了。（—No，I'mnot．—不，我没准备好。）（2）实义动词型：句中的谓语动词为实义动词（也叫行为动词）：a．肯定句中，只出现实义动词，如：Igetupinthemorning．我早晨起床。b．否定句中，要在实义动词前面加do（does）＋not，do（does）作助动词，本身无意义，常与not缩写成don't（doesn't），如：Idon'tlikevegetables．我不喜欢蔬菜。c．一般疑问句，要在句子开头加助动词Do（does），句尾用问号，简略答语用Yes，主语+do（does）．或No，主语+do（does）＋not．如：—Doyoulikeoranges？—你喜欢桔子吗？—Yes，Ido．—是的，我喜欢。（—No，Idon't．—不，我不喜欢。）3,一般现在时的用法1)经常性或习惯性的动作，常与表示频腮度的时间状语连用。时间状语：every…,sometimes,at…,onSundayoften,usually,sometimes,always,every(day等),once/twice,a(week等),on(Sunday等),never,inthe(morning等)Ileavehomeforschoolat7everymorning.2)客观真理，客观存在，科学事实。Theearthmovesaroundthesun.ShanghailiesintheeastofChina.Lighttravelsfasterthansound.(光传播比声音快)3)表示格言或警句中。Pridegoesbeforeafall.骄者必败。注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。例：Columbusprovedthattheearthisround..4)表示十分确定会发生(如安排好的事情)或按照时间表进行的事情,用一般现在可以表达将来,句子中可以有将来时间。如：ThetrainforHaikouleavesat8：00inthemorning.(开往汉口的列车上午8点开车)5)在时间状语从句中(以when,after,before,while,until,assoonas等引导)和条件状语从句中(以if,unless引导),用一般现在时代替一般将来时,句子可以有将来时间。如：PleaseringmeupassoonasyouarriveinGermany.(你一到德国就给我打电话)/Ifitrainstomorrow,wewillhavetostayathome.(如果明天下雨我们就只好呆在家)6)一般现在时用于倒装句中可以表示正在发生的动作,动词以come,go为主。如：Herecomesthebus.(车来了)/Theregoesthebell.(铃响了)。7)人的心理活动和感官动作一般用一般现在时而不用现在进行时表达,常见动词有：like,love,hate,dislike,want,wish,hope,think(认为),understand,remember,forget,mean,need,hear,feel,see.如：Ithinkitisgoingtosnow.(我想天要下雪了)/Ireallyhopeyoucanenjoyyourstayhere.(我真的希望你愉快地呆在这儿)8)现在时刻的状态、能力、性格、个性。Idon'twantsomuch.AnnWangwritesgoodEnglishbutdoesnotspeakwell.比较：NowIputthesugarinthecup.Iamdoingmyhomeworknow.第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Nowwatchme,Iswitchonthecurrentandstandback.第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。一般现在时-表达方法主要通过\o"谓语动词"谓语动词的变化和用时间词语来表示，其中最主要的是谓语动词的变化。现在一般时动词变化的规则是：1.如果主语是\o"名词复数"名词复数和\o"第一人称"第一人称I、we，第二人称单复数you和第三人称复数they时，谓语动词不用做任何变化，即仍然用动词原型表示：Weusuallygotoschoolat7:30.我们通常7:30上学去。[go]Myparentsgivetenyuantomysistereveryweek.我父母每星期给我妹妹十元钱。[give]2.主语是任何一个\o"单数名词"单数名词或者是\o"第三人称单数"第三人称单数she、he、it时，谓语动词要用单三形式。特别提一点：\o"不可数名词"不可数名词也算作\o"单数"单数处理。3.谓语动词的变化规律是：(1)在动词后加-s，-esread-reads，write-writes，say-says(2)以s，x，ch，sh结尾的词加-esteach-teaches，wash-washes，guess-guesses(3)以\o"辅音字母"辅音字母+y结尾的词变y为i再加-estry-tries，carry-carries(4)特殊变化的词be(是)-am,is,areIam;she/he/it,名词单数都用is;we,you,they,名词复数都用arehave(有)-have,hasI,we,you,they,名词复数都用have;she/he/itis,名词单数都用has1.Iamastudent．2.Sheisn'tateacher．—Areyouready？—Yes，Iam/No，I'mnot．3.Igetupinthemorning．4.Idon'tlikevegetables．5.—Doyoulikeoranges？—Yes，Ido．/No，Idon't．6.Jackoften___________(listen)totheradio.7.________you_________(brush)yourteetheverymorning.8.What
