1、初一英語(yǔ)一般現(xiàn)在時(shí)講解及其練習(xí)1定義：表示通常性、規(guī)律性、習(xí)慣性的狀態(tài)或者動(dòng)作（有時(shí)間規(guī)律發(fā)生的事件）的一種時(shí)間狀態(tài)。2基本結(jié)構(gòu)A.如果謂語(yǔ)動(dòng)詞是實(shí)義動(dòng)詞的結(jié)構(gòu) 結(jié)構(gòu)：肯定式:主語(yǔ)+動(dòng)詞原形/動(dòng)詞的第三人稱(chēng)單數(shù)否定式:主語(yǔ)+助動(dòng)詞 don't/doesn't +動(dòng)詞原形+其他疑問(wèn)式:Do/Does+主語(yǔ)+動(dòng)詞原形+其他簡(jiǎn)略回答:(肯)Yes,主語(yǔ)+do/does (否)No,主語(yǔ)+do/does not 縮寫(xiě)形式: don't = do not doesn't =does not注意：have的第三人稱(chēng)單數(shù)為has 疑問(wèn)句型謂語(yǔ)動(dòng)詞是實(shí)義動(dòng)詞，方法是在主語(yǔ)前加助

2、動(dòng)詞do或does構(gòu)成，句中動(dòng)詞要改用原型動(dòng)詞。do 用于第一人稱(chēng)和名詞復(fù)數(shù)，does 用于第三人稱(chēng)單數(shù)和名詞單數(shù)或不可數(shù)名詞。 Do you know it？Yes, I do. / No, I don't. Does she have a pen？Yes, she does. / No, she hasn't.have 這里是實(shí)義動(dòng)詞 Do they play basketball after school? Yes, they do. / No, they don't.否定句型謂語(yǔ)動(dòng)詞是實(shí)義動(dòng)詞，是在謂語(yǔ)動(dòng)詞前加do not 或does not，謂語(yǔ)動(dòng)詞改用動(dòng)詞原

3、型。 I don't have luch at home. Mr.Jimmy doesn't know French.They don't play basketball on the sports ground. 肯定式疑問(wèn)式否定式否定疑問(wèn)式I work.Do I work?I do not work.Do I not work?You work.Do you work?You do not work.Do you not work?We work.Do we work?We do not work.Do we not work?They work.Do they w

4、ork?They do not work.Do they not work?He(She,It) works.Does he(she,it) work?He(She,It) does not work.Does he(she,it) not work?B如果謂語(yǔ)動(dòng)詞是be/情態(tài)動(dòng)詞的結(jié)構(gòu) 結(jié)構(gòu):主語(yǔ)+be+其他 主語(yǔ)+情態(tài)動(dòng)詞+動(dòng)詞原形 1）be動(dòng)詞的第一人稱(chēng)單數(shù)為am，第三人稱(chēng)單數(shù)為is，其他人稱(chēng)為areBe動(dòng)詞順口溜用法： 我用am ，你用 are ，is 用于他，她，它, 單數(shù)is，復(fù)數(shù)are.肯定式:主語(yǔ)+ am /is/are +其他否定式:主語(yǔ)+ am/is/are +not +

5、其他疑問(wèn)式:Am /Is /Are + 主語(yǔ)+ 其他?簡(jiǎn)略回答: (肯) Yes,主語(yǔ) + am/ is /are (否) No,主語(yǔ) + am /is/are not 縮寫(xiě)形式: I'm = I am That's =That is We're =We are What's= What is You're = You are Who's = Who is They're =They are Where's =Where is He's =He is She's =She is It's = It is i

6、sn't=is not aren't=are not 疑問(wèn)句型1.對(duì)于謂語(yǔ)動(dòng)詞或助動(dòng)詞是 be、can/may 等，將這些詞移到主語(yǔ)前面。 Are you students？Yes, we are. / No, we aren't. Is Jane in the classroom? Yes, he is. / No, he isn't. Is there any water in the glass? Yes, there is. / No, there isn't. Can you swim? Yes, I can. / No, I can'

7、t. 否定句型謂語(yǔ)動(dòng)詞或助動(dòng)詞是 be、can/may/ 等，在將助動(dòng)詞后加not. I am not at college. Mr. Wang isn't 50 years old. You may not go now. 2） 情態(tài)動(dòng)詞can/may的用法同be動(dòng)詞Eg: I can do my homework. She can see a picture.3. 動(dòng)詞的表達(dá)方法主要通過(guò)謂語(yǔ)動(dòng)詞的變化和用時(shí)間詞語(yǔ)來(lái)表示，其中最主要的是謂語(yǔ)動(dòng)詞的變化。現(xiàn)在一般時(shí)動(dòng)詞變化的規(guī)則是： A 實(shí)義動(dòng)詞1.如果主語(yǔ)是名詞復(fù)數(shù)和第一人稱(chēng)I、 we ，謂語(yǔ)動(dòng)詞不用做任何變化，即仍然用動(dòng)詞原型表示：

8、 We usually go to school at 7:30. 我們通常7:30上學(xué)去。go My parents give ten yuan to my sister every week.我父母每星期給我妹妹十元錢(qián)。give 2.主語(yǔ)是任何一個(gè)單數(shù)名詞或者是第三人稱(chēng)單數(shù)，謂語(yǔ)動(dòng)詞要進(jìn)行必要的變化。特別提一點(diǎn)：不可數(shù)名詞也算作單數(shù)處理。 情況構(gòu)成方法 讀音例詞一般情況加 -s 清輔音后讀/s/ 濁輔音和元音后讀/z/ swim-swims；help-helps；以s,sh,ch,x，o等結(jié)尾的詞 加 -es 讀/iz/ Passes, finishes, teaches, goes以輔音

9、字母+y結(jié)尾的詞變y 為i再加es 讀/z/study-studies 實(shí)義動(dòng)詞單數(shù)變法規(guī)則：寫(xiě)出下列動(dòng)詞的第三人稱(chēng)單數(shù)：study play go come help teach lie listen begin open sit wash guess cut run eat B 助動(dòng)詞 a. 基本助動(dòng)詞be (是) - am, is, are I 用am ；she/he/it, 名詞單數(shù)都用 is ；we, you, they, 名詞復(fù)數(shù)都用are b. 基本助動(dòng)詞 have (有) - have, has I, we, you, they, 名詞復(fù)數(shù)都用have ；she/he/it i

10、s, 名詞單數(shù)都用 has c. 基本助動(dòng)詞do-do does I, we, you, they, 名詞復(fù)數(shù)都用do ；she/he/it is, 名詞單數(shù)都用 doesd.情態(tài)助動(dòng)詞，不論單復(fù)數(shù)、不論什么人稱(chēng)都沒(méi)有變化，都用 can, may 等。而且，句子中有了助動(dòng)詞，謂語(yǔ)動(dòng)詞就不需要有任何變化了，即用動(dòng)詞原形表示。 Lucy is at home now. 露茜現(xiàn)在在家。 We have six classes every day. 我們每天上六節(jié)課。 Jack likes Chinese food very much. 杰克很喜歡中國(guó)飲食。 We can see some pictu

11、res on the wall. 我們能看到墻上的畫(huà)。4 具體運(yùn)用1.表示經(jīng)常的或習(xí)慣性的動(dòng)作，常與表示頻率的時(shí)間狀語(yǔ)連用。 一般現(xiàn)在時(shí)的時(shí)間狀語(yǔ)有：usually,often（經(jīng)常）, always（總是）, sometimes（有時(shí)）, on Sundays/Mondays ,today, every day ( week, month, year,) , this year, once a week ( month, year,) 一周（月，年）一次every morning/night/evening/day/week,from time to time,twice a week

12、9; 注意：行為動(dòng)詞的一般現(xiàn)在時(shí)中涉及了頻度副詞，用法：常見(jiàn)的頻度副詞有：often ,always ,usually ,never ,sometimes等用于行為動(dòng)詞之前，be/助、情態(tài)動(dòng)詞之后.e.g. I leave home for school at 7:00 every morning.I don't usually get up at 6 oclock . He often goes to school by bike. 2.表示客觀事實(shí)和普遍真理。 e.g Shanghai lies in the east of China. Two an

13、d two are four.二加二等于四。 The earth moves around the sun.地球繞著太陽(yáng)轉(zhuǎn)。4.表示主語(yǔ)現(xiàn)在具備的性格、能力、特征和狀態(tài)。 e.g. He likes   English very much. 他非常喜歡英語(yǔ)。She is a student.
