1、精品文档一般现在时与一般过去时的讲解与练习一般现在时的讲解及练习一般现在时是英语中应用最广泛的时态之一,是英语语法重点。一般现在时表示:1 .经常性、习惯性的动作或存在的状态。e.g. I go to school on foot. He is very busy now.2 .表示主语的特征、性格、能力、爱好等。e.g. He can swim. I work hard. I like watching TV.3 .表示客观真理。e.g. There are seven days in a week. The moon moves round the earth.构成1. be动词:主语+b
2、e(am,is,are)矶它。如: I am a boy.我是一个男孩。2.行为动词:主语+行为动词什其它)。如: We study English.我们学习英 语。当主语为第三人称单数(he, she,it)M,要在动词后加"-s"或"-es"或变"y为 “iesOf: Mary likes Chinese.玛丽喜欢汉语。Miss Gu teaches us English顾老师教我们英语。 She studies Chinese every da她每天学习语文。第三人称单数的动词变化规则(1) 多数动词直接加 s: runs gets li

5、ass.14 .The student(speak) Chinese after class.15 . you study English at school ? Yes , I. ( do )16 . He like swimming . ( not )其句式变化可分为两种情况:1 .含有be动词的要在be上做变化:E.g. Danny is a good studentDanny isn ' t a good student.Danny a good student?2 .表示动作,一般人称作主语的,变否定句须在动词前加助动词don't;变一般疑问句须在句首加助动词do。E
6、.g. They have lunch at 12:00. They dont have lunch at 12:00.Do they have lunch at 12:00?单三人称做主语的,变否定句须在动词前加助动词doesn't;变一般疑问句须在句首加助动词does。E.g. Jenny speaks English very well. Jenny doesnspeak English very well. Does Jenny speak English very well?其时间状语为 often、usually、always、sometimes等频率副词,onSaturd
7、ays in the morning(afternoon evening) > every day等。夫常见错误如下:一、be动词与行为动词同时出现在句子中例: We are plant (plant) the trees in spring.解析:学生往往会用汉语的思维方式去翻译,就成了我们是在春天植树”。这是学习英语最忌讳的,要看语法是不是正确,在英语中,be是表状态,do是表动作,两种动词不能同时出现在句子中,可记住如下口诀:英汉语言有差异,be、do不能放一起,仔细琢磨细分析,语法千万要牢记。 ”二、单三人称形式易出错例:1 He plaies (play) football v
8、ery well. 2 Danny gos (go) to school at 7:10.解析:1以辅音字母加y结尾的动词变单三人称形式才能把 y换成i再加es; 2与名词变复数不同,变单三人称形式以o结尾的词要加es.三、在句式变换时易出错例:1 Does Jenny has (has) a good friend?2 Brian doesn ' t lives (not live) in China.答案:1 Does have 2 doesn ' t live解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:见助动,用原形此口诀也可推广用于一般过去时态中。e.
9、g. He didn't go homeyesterday.四、对do的理解易出错例: We don' t (not do) our homework in the afternoon.答案:don' t do解析:do是一个比较难理解的词,它有三个含义:a)是所有行为动词的总称;b)是助动词,无实义;c)是一个具体的行为动词 做,干”。此句中给出的do指 做,干”,not指把此句变为否定句,故须在do前加助动词don't五、对主语的数判断有误例: Li Ming with me are (be) in Beijing.答案:is解析:表面一看是我和李明两个人在
10、北京”,但with在此做伴随状语,不能 做主语,故用is.另外,宾语从句中,从句部分若是表示客观真理,不管主句是何时态,从 句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般 现在时。自我检测:(一)、单选1. Jenny in an office.

14、edjudged raised以辅音字母+y结尾的动词,把-y变为-i再加-ed,如:Studied tried copied cried carried以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,冉加 -ed,如:stopped begged dragged dropped planned dripped注:不规则动词的过去式变化规律性不强,须多加记忆。go - went make - made get - got buy - bought come - came fly-flew一般过去式的用法:表示过去某一时刻或某一段时间内所发生的动作或情况,不强调动作对现 在的影响,只说明过

17、般过去时并不难,表示过去动作、状态记心问。动词要用过去式,时间状语句末站。否定句很简单,didn't站在动词原形前,其它部分不要变。一般疑问句也好变,did放在句子前,主语、动词原形、其它部分依次站特殊疑问句也简单,疑问词加一般疑问句记心问。最后一条请注意,动词过去式要牢记。.用所给词的适当形式填空。1. Tom and Mary(come) to China last month.2. Mike(not go) to bed until 12 o' clock last night.So he(get ) up late.3. Mary(read) English yeste
