一般現(xiàn)在時(shí)及三單綜合

1、時(shí)態(tài)一：一般現(xiàn)在時(shí)動(dòng)詞第三人稱單數(shù)一、定義：1、經(jīng)常性、習(xí)慣性的動(dòng)作；2、事物或人物的特征或狀態(tài)；3、客觀現(xiàn)實(shí)、真理或規(guī)律。Example：1. 表示經(jīng)常性、習(xí)慣性、永久性、頻率性的動(dòng)作，通常與副詞often, usually, always, every day (year/ month ), once (twice, three times) a day（week/moth/year）, sometimes，in the morning/afternoon/evening， on Sundays等時(shí)間狀語連用。They usually go to school by bike.I take

2、 the medicine three times a day.She helps her mother once a week. 2.表示事物或人物的特征、狀態(tài)Marys father is a policeman.There are 50 students in my class.3. 表示客觀真理，科學(xué)原理，自然現(xiàn)象等客觀事實(shí)或格言、諺語等。 The sun rises in the east and sets in the west every day. The man who has never been to the Great Wall is not a real man. To

3、morrow is Tuesday.二、結(jié)構(gòu)：肯定句： 主語 + v原 /v“三單” (主語+ Be/情態(tài)動(dòng)詞/行為動(dòng)詞（原形或三單）+其它)句型Be型（情態(tài)動(dòng)詞型）Do型否定句主語 + Be動(dòng)詞/情態(tài)動(dòng)詞+not主語+ dont/doesnt +V原形一般疑問句Be動(dòng)詞/情態(tài)動(dòng)詞+主語+其它Do/Does+主語+ V原形肯定回答：Yes，主語+ Be動(dòng)詞/情態(tài)動(dòng)詞.肯定回答：Yes，主語+ do/does.否定回答：No, 主語+ Be動(dòng)詞/情態(tài)動(dòng)詞+not.否定回答：No, 主語+ dont/doesnt.否定句：主語+Be/情態(tài)動(dòng)詞/do/dose+not+其它一般疑問句：Be/情態(tài)動(dòng)詞

4、/do/dose + 主語+其它特殊疑問句：特殊疑問詞 + Be 動(dòng)詞/情態(tài)動(dòng)詞/do/dose + 主語+其它（對主語提問除外）對主語提問的特殊疑問句= 特殊疑問詞+主語+動(dòng)詞原形/三單（肯定句的結(jié)構(gòu)）+？總結(jié)：行為動(dòng)詞表示具體的動(dòng)作，be動(dòng)詞表示狀態(tài)，情態(tài)動(dòng)詞表示態(tài)度。在做肯定陳述的時(shí)候，運(yùn)用的規(guī)則是：有do無be；無do一定要加be。另外，一定要小心：在做句型轉(zhuǎn)換（否定、疑問）的時(shí)候，要分別遵守自己的約定：行為動(dòng)詞要請do/does幫忙；有be就直接用be(be提前變成問句，在后面加上not變成否定句)。三、第三人稱單數(shù)（三單） 1、除了我（I ）和你(you ) 我們（we） 你們(y

5、ou) 他們(they) 之外都是三單,人稱代詞he, she, it是第三人稱單數(shù)。如： He likes watching TV. 他喜歡看電視。 She has lunch at twelve. 她十二點(diǎn)吃午餐。 It looks like a cat. 它看起來像只貓。2、單個(gè)人名、地名或稱呼作主語；是第三人稱單數(shù)。如： Han Mei looks like her mother. 韓梅看起來像她的母親。 Beijing is in China. 北京在中國。 Uncle Wang often makes cakes. 王叔叔經(jīng)常做蛋糕。 3、單數(shù)可數(shù)名詞或this / that /

7、表有毛病。 This is a pen. 這是一支鋼筆。 That is an eraser. 那是一塊橡皮擦。5、不可數(shù)名詞作主語時(shí)為第三人稱單數(shù)。如： The milk is in the glass. 牛奶在玻璃杯里。 The bread is very small. 那面包很小。6、當(dāng)數(shù)字或字母作主語時(shí)，看作第三人稱單數(shù)。如： 6 is a lucky number. 6是個(gè)吉利數(shù)字。 I is a letter. I是個(gè)字母。 四、動(dòng)詞三單變化規(guī)則 1、一般情況下加S ：ask-asks learn-learns work-works get-gets likelikes playp

9、情態(tài)動(dòng)詞型否定句：直接在be動(dòng)詞或情態(tài)動(dòng)詞后面加not.疑問句：則把be動(dòng)詞或情態(tài)動(dòng)詞(can,could等等)提到主語的前面例：陳述句：She is a student. 疑問句 Is she a student? 否定句 She is not a student.陳述句：I can swim. 疑問句 Can you swim? yes,I can. No,I cant. 否定句 I can not swim.2、Do型 否定句：主語 + dont/ doesnt + 謂語動(dòng)詞原形疑問句：Do / Does + 主語 + 動(dòng)詞原形例：陳述句：We get up at 7:00 every

10、morning. 否定句We dont get up at 7:00 every morning.疑問句Do you get up at 7:00 every morning? 陳述句：She has a little brother. 否定句 She doesnt have a little brother.疑問句 Does she have a little brother?3、注意“變變變變”（1）I、weyou、you（2）句號(hào)變問號(hào)；（3）Does（三單）、Did（過去式）來幫忙，動(dòng)詞變V原； （4）some-any something-anything somebody- anyb
