一般現(xiàn)在時(shí)知識(shí)點(diǎn)

1、一般現(xiàn)在時(shí)基本用法介紹：一、一般現(xiàn)在時(shí)的功能：（一）表示經(jīng)常性發(fā)生或反復(fù)發(fā)生習(xí)慣性的動(dòng)作；這種用法中經(jīng)常用到：often經(jīng)常, usually通常, always總是， every每個(gè), sometimes有時(shí)， at在幾點(diǎn)鐘，等做時(shí)間狀語(yǔ)，也可以說(shuō),這是一個(gè)一般現(xiàn)在時(shí)語(yǔ)法的特征。如：I usually get up at six.（表示經(jīng)常性的事情。）He often has dinner at home.（經(jīng)常性事情）They always go to school on foot.他們總是步行去上學(xué)。（“總是”表示經(jīng)常性的事情）（二）表示事物或人物（主語(yǔ)）的現(xiàn)在的特征、狀態(tài)，這種情形下，

2、通常不帶時(shí)間狀語(yǔ)。如：She likes bread, but she doesnt like pizza .Do you speak English?The sky is blue.天空是藍(lán)色的。He works in a big company.他在一家大公司工作。（三）表示客觀(guān)現(xiàn)實(shí)、客觀(guān)真理、科學(xué)事實(shí)、格言等；如：The earth goes around the sun.地球繞著太陽(yáng)轉(zhuǎn)。There are four seasons in a year.The sun always rises in the east.Walls have ears. 隔墻有耳。（四）表示將來(lái)。如：1.表

4、d skirt. This is a T-shirt. It's redThese are trousers. They're black.The trousers and the T-shirt are nice.This is the way I read a book, on a Tuesday Morning小貼士：1. Be 動(dòng)詞： 也就是： am is are 2. am 用在第一人稱(chēng)：“ I ”后面；3. is的用法：（1） is 用在 he she it 等第三人稱(chēng)單數(shù)的主語(yǔ)后面；（三單：“不是你，不是我，只有一個(gè)！”一般現(xiàn)在時(shí)時(shí)才變化）比如：He、 she、

5、it、 Li Ming 、Xiao Hong、this、that以及this、that修飾的部分后面等等，但是Li Ming and Xiao Hong這就不是第三人稱(chēng)單數(shù)了，而是復(fù)數(shù)應(yīng)該用： are（2）不可數(shù)的名詞做成分用到be動(dòng)詞時(shí)也要用：is3. are 的用法：（1）第一人稱(chēng)復(fù)數(shù)：we ；（2）第二人稱(chēng)即：you(單數(shù)、復(fù)數(shù)的后面)；（3）第三人稱(chēng)復(fù)數(shù)they后面、 以及 these ，those或these ，those修飾的部分等，表示復(fù)數(shù)的地方也就是說(shuō)：記住am is應(yīng)該用的地方就可以了，別的地方都是用的are。This is a dress. This is這是These a

6、re socks. These are這些是These are new shorts. This is a new dress. These are his shoes? This is her skirt. The trousers are nice.The trousers and the T-shirt are nice.（二）不含有be動(dòng)詞，即含有實(shí)意動(dòng)詞的一般現(xiàn)在時(shí)；這里只有一個(gè)需要記住的地方：就是第三人稱(chēng)單數(shù)的后面，動(dòng)詞要加“-s”或“-es”，別的地方就只用動(dòng)詞原形就可以了。（三單：“不是你，不是我，只有一個(gè)！”一般現(xiàn)在時(shí)時(shí)才變化）舉例：I like the shirt and

8、omework. 二、一般現(xiàn)在時(shí)句子的變化：否定句、疑問(wèn)句, 特殊疑問(wèn)句，其中特殊疑問(wèn)句放在后面介紹。否定句：簡(jiǎn)單來(lái)說(shuō)，就是表示否定的句子。一般疑問(wèn)句：一般疑問(wèn)句是疑問(wèn)句的一種。它是只用yes（是）或no（否）來(lái)回答的句子。特殊疑問(wèn)句：以特殊疑問(wèn)詞開(kāi)頭，對(duì)句中某一成分提問(wèn)的句子叫特殊疑問(wèn)句。常用的疑問(wèn)詞有：what 、who 、whose 、which 、when 、where 、how 、why等。（一） 含有be動(dòng)詞的一般現(xiàn)在時(shí)的變化（含有情態(tài)助動(dòng)詞）。情態(tài)助動(dòng)詞： can 1)否定句：主語(yǔ)+ be動(dòng)詞（情態(tài)動(dòng)詞） + not +其它。如：He is a worker. He is not

9、 a worker.I can show you. I cant show you .2)一般疑問(wèn)句：將be動(dòng)詞（情態(tài)動(dòng)詞）提到句子前面即可，即：Be （情態(tài)動(dòng)詞）+ 主語(yǔ) + 其它。He is a worker. He is not a worker.Is he not a worker? Yes , he is. No , he isnt.I can show you. I cant show you .Can you show me ?Yes ,I can. No , I cant.I am a student . I am not a student .Are you a studen

11、后面的（s或es）。當(dāng)主語(yǔ)為第三人稱(chēng)單數(shù)時(shí)，要用doesn't構(gòu)成否定句。主語(yǔ)+doesn't/ I don't+動(dòng)詞原形（動(dòng)詞原來(lái)形狀）如：He doesn't often play.I don't like bread.2.一般疑問(wèn)句：Do( Does ) +主語(yǔ)+壯語(yǔ)+動(dòng)詞原形+其它。這里的“Do( Does )”只是為了幫助形成一般疑問(wèn)句，沒(méi)有實(shí)際意思！這里需要注意幾點(diǎn)：（1） 當(dāng)主語(yǔ)為第三人稱(chēng)單數(shù)時(shí)，要用does替換do構(gòu)成一般疑問(wèn)句。（2） 主語(yǔ)三單時(shí)，句子中的動(dòng)詞要變?yōu)閯?dòng)詞原形。如：- Do you often play football?

12、 肯定形式： Yes, I do. 否定形式： No, I don't.如：- Does she go to work by bike?肯定形式回答：Yes, she does. 否定回答： No, she doesn't.3.小貼士：（這里是平時(shí)我們注意積累的地方，可以把我們平時(shí)的積累、感悟記在這里?。?）“含有be動(dòng)詞的一般現(xiàn)在時(shí)”這里句型的變化上邊已經(jīng)說(shuō)過(guò)，但是并不局限于一般現(xiàn)在時(shí)！更為準(zhǔn)確的表達(dá)是：含有be（am、is、 are、 was、 were）動(dòng)詞的句子，將其提到句首，句末打上問(wèn)號(hào)即可；（2）一般疑問(wèn)句的回答，開(kāi)頭往往是yes或no 。也就是說(shuō)，只要能看出是一

13、般疑問(wèn)句，那么它的回答開(kāi)頭往往就是yes或no ；（3）如遇第一人稱(chēng)，最好將其變成第二人稱(chēng)；舉例：I am a teacher.否定句： I am not a teacher.一般疑問(wèn)句：Are you a teacher?肯定回答：Yes ，I am . 否定回答：No ,Im not . My father is a teacher.否定句：My father is not a teacher. 一般疑問(wèn)句：Is your father a teacher? 肯定回答：Yes ，he is . 否定回答：No ,he isnt（4）在一般疑問(wèn)句和否定句中，要表達(dá)“一些”時(shí) ，someany

14、；但是，如果這個(gè)問(wèn)句是用來(lái)表達(dá) “建議、請(qǐng)求、邀請(qǐng)”等交際功能時(shí) ，而且希望聽(tīng)到肯定回答時(shí)，應(yīng)該用some.Is there any tea in the cup?Do you have any children?May I have some fish?Would you like some tea?Shall we buy some vegetables?Can I borrow some money from you?Why not have some bread?How about some orange juice?（三）特殊疑問(wèn)句：構(gòu)成：疑問(wèn)詞+一般疑問(wèn)句，同時(shí)注意去掉劃線(xiàn)部分。如

15、：Where is my bike?How does your father go to work?I usually play football on Friday afternoon.When do you usually play football ? I usually play football on Friday afternoon.What do you usually do on Friday afternoon?Who is singing?Who often helps your mother?（四）一般現(xiàn)在時(shí)中,動(dòng)詞+s的變化規(guī)則即：動(dòng)詞三單的變化規(guī)律：（三單：“不是你，
