『叄』 初中八年級英語所有語法

現在完成時
1.構成
現在完成時是由助動詞 have(has)+動詞的過去分詞構成。助動詞說明該謂語是屬於現在時范圍。它和主語的人稱、數要保持一致。過去分詞是主要的謂語動詞,說明句子的意義。
2.用法
(1)表示動作發生在過去某個不確定的時間,但對現在留下了某種影響和結果。常被just, already, yet 等副詞修飾。常與非延續性動詞連用。 如:
-Have you had lunch yet? -Yes, I have. I've just had it. 你(已經)吃午飯了嗎? 我剛剛吃過。(現在我不餓了)
(2)表示從過去某一時刻開始一直持續到現在的動作或狀態。這個動作可能剛停止,可能仍然在進行。常用延續性動詞,常帶有for和since(自從)等表示一段時間的狀語。
如:He has taught here since 1981. 他自1981年就在這兒教書。(可能還要繼續教)
I haven't seen her for four years. 我有四年沒見到她了。
(3)表示說話前發生過一次或多次的動作,現在成為一種經驗,一般譯為漢語「過」,常帶有twice, ever, never, three times等時間狀語。
如: I have been to Beijing twice. 我去過北京二次。
3.結構
1)陳述句結構:主語+have( has)(not)+過去分詞+其它。have not=haven』t has not= hasn』t.
2) 一般疑問句結構:Have( Has )+主語+過去分詞+其它?
3) 特殊疑問句:特殊疑問詞+have(has) +主語+ 過去分詞+其它?
e.g. He has already finished his homework.
He hasn』t finished his homework yet.
Has he finished his homework yet? --Yes, he has. / No, he hasn』t. / No, not yet.
4.現在完成時的時間狀語
1)現在完成時屬於現在時范圍,故不能和過去的時間狀語連用。如: yesterday, last Sunday, in1990, three years ago等。但是,在強調動作產生的後果和影響時,可以和一些表示不確定的時間狀語連用。
a. 用副詞already和yet。already一般用於肯定句中,yet一般用於否定句和 疑問句中。如:We have already finished our homework.我們已完成作業了。
They haven't finished their homework yet.他們還沒有完成作業。
b. 用ever 和never。多用於否定或疑問句中,表示「曾經」或「從未「等。 如:-Have you ever been to the Great Wall?你曾經去過長城嗎?
-I have never been to the Great Wall.我從未去過長城。 c. 用表示到說話為止的過去時間狀語,如just(剛剛), before(以前), up to now(直到現在)/ until now, in the past (few years/ three days 等), so far (迄今為止) recently 等。 例如:I have seen her before, but I can not remember where. 我以前見過她,但記不起在哪裡見過。
He has been there three times the last few days. 近幾年他去過那裡三次了。 d.用包括「現在」在內的時間狀語,如:today, this morning (month ,year, term等.例如:-Have you met him today? - No, I haven't. 今天你見過他嗎?我沒有。
How many times have you been there this year? 今年你去過那裡多少次?
2) 現在完成時可以和帶有since或for等表示「一段時間」的狀語連用,表示動作或狀態從某一時刻開始,一直持續到現在。如:I haven't seen him for two years. 但是,像come, arrive, buy等終止性動詞不能與表示「一段時間」的狀語連用。要用,必須改為「be(在)」等延續性動詞來表述。現歸納總結一下由非延續性動詞到延續性動詞的轉換:
arrive → be here begin (start) → be on die →be dead come back → be back leave → be away fall ill (sick, asleep) → be ill (sick, asleep) go out →be out finish →be over put on →wear 或be on get up →be up join →be in / be a member of… open → be open close →be closed go to school→ be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study → study come to work→ work
如:He has been a soldier for three years.他參軍三年了。或He has been in the army for there years. 不可以說He has joined the army for there years.
His father has been dead for two years.他父親去世二年了。(不可以說has died)
The film has been on for ten minutes.電影已開始十分鍾了。(不可以說has begun)
We have studied English for three years. (不可以說have begun) 我們(開始)學英語已三年了。
5. 現在完成時和一般過去時的區別
現在完成時和一般過去時都表示在過去完成的動作。但現在完成時強調的是這一動作與現在的關系。如對現在產生的結果或影響等,而一般過去時只表示動作在過去某一時刻發生,不表示和現在的關系。試比較:
I have lost my new book. 我把新書丟了。(現在還未找到)
I lost my new book yesterday. 我昨天把新書丟了。(昨天丟的,現在找到與否沒說明)
6.幾點注意事項 (1)have been(to)與have gone( to)的區別:have been(to) 表示「去過某地(現在已經回來了)」,可用於各人稱;have gone(to) 表示「去某地了(說話時某人不在當地)」,常用於第 三人稱,前者可與once ,never, several times等連用,後者則不能。如:They have been to Beijing twice.他們去過北京兩次。 He has gone to Beijing . 他去北京了。 (2)「It is或has been + 一段時間+ since引導的時間狀語從句」表示「某人干某事已經多長時間了」。since從句的謂語要用非延續性動詞 若動詞延續,則譯成相反的意思。如:It is two years since his father died. =His father has been dead for two years.他父親去世已有三年了。 It is two years since his father lived here. 他爸爸不住這兒已有三年了。 (3)終止性動詞現在完成時的否定式,已變成一種可以延續的狀態,因此可以和表示一段時間的狀語連用。如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。 (4).提問for短語或since狀語用how long。
(5).完成時的否定形式與比較級連用表達最高級含義。如:
I have never seen a better film.我從未看過一部更好的電影。(這部最好)
註:否定式與比較級連用表示最高級含義不一定用於完成時態。如:
--- What about going fishing? --- I can』t agree more.(我再同意不過了哦)
.語法—直接引語變間接引語(多數情況下變為賓語 從句)
(1). 直接引語如果是陳述句,變為間接引語時,用連詞that 引導(口語中可以省略引導詞)賓語從句。把下列句子變為間接引語或直接引語:
a. 「I』ll visit my aunt tomorrow.」 Lily said. ____________________________.
b. Our teacher often say to us,」 It』s important to finish your homework.」
_______________________________________________________
c. They said they would meet at 9:00 p.m. that night.
「_______________________________________.」they said.
d. Lana said that she wasn』t mad at Marcia anymore.

____________________________________________________.
b. 「Tell me the news, please.」 Li Hui said to me.
____________________________________________________.

2. if 條件句 在一般將來時的句子里(指主句),時間狀語從句、條件狀語從句等的謂語動詞用一般現在時代替將來時。當主句含有情態動詞或主句為祈使句時,從句也用一般現在時。如:You must pay for it if you lose it.

附加疑問句
附加疑問句由「陳述句 + 附加疑問句」兩部分構成。一般有兩種形式:前肯後否或前否後肯。對附加疑問部分應注意以下幾點: 1)主語只能用人稱代詞;2)附加疑問句的not必須與(be /助/情)縮寫;3)附加疑問句的時態必須與陳述部分的時態一致。
Tom is a worker, isn』t Tom? (改錯) _______ You can swim, can not you? ( 改錯) ______
特別注意以下幾種反意疑問句
1.陳述部分含否定意味的詞如few,little,never,nothing,nobody,no,hardly,none,seldom等時,附加疑問句應使用肯定形式;但如果陳述句部分含有un-, in-, im-, dis-等否定前綴構成的派生詞時,該陳述句部分仍做肯定處理,疑問部分用否定形式。

『柒』 仁愛英語八年級上冊語法

Unit 1 Playing Sports
Topic 1 What』s your favorite sport?
重點語法
一般將來時:
(一)be going to 結構: ①表示主語進行某一將來行動的打算、意圖。這種打算常經過預先考慮並含有自己做好某些准備的意思,因此通常認為用be going to表達的行動很可能會見諸實踐。 如:I』m going to play basketball with my classmates this Sunday.
我打算本周日和同學們一起打籃球。
She is going to buy a sweater for her mother.
她打算為她媽媽買一件毛衣。
②表預測。指根據跡象推測,而且馬上或很快就要發生。
如:Look at those clouds. It』s going to rain. 瞧那些烏雲!快要下雨了!
(二) will + 動詞原形:表示單純的將來事實,常與表將來的時間狀語如:tomorrow, soon, later, next time(week/month/year…)等連用。will not = won』t; 縮略形式為』ll.
表示作出立即的決定。這種意圖並未經過事先的考慮或計劃,是臨時的一種決定。
如:a. ----Please put your things away, Tom. 湯姆,把你的東西收拾好。
----I』m sorry. I』ll do it right away. 對不起。我馬上就去做。
b. ----Would you like coffee or tea? 您要咖啡還是茶?--I will have a cup of tea,please. 我要一杯茶。c. Don』t worry. I』ll help you. 別擔心。我會幫你的。
表示預測。指說話人對於將來的看法、假設和推測。
如: I』m sure our team will win next time. 我確信下次我們隊會贏。
Maybe she will go to the gym. 也許她會去體育館。
表示許諾。如: I』ll do better next time. 下次我會做得更好的。
I』ll visit you tomorrow. 明天我會去看你的。
句式:肯定句:I/She/He/They will go to play baseball soon.
否定句:I/She/He/They won』t go to play baseball soon.
一般疑問句:Will you/she/he/they go to play baseball soon?
回答:Yes, I/she/he/they will. No, I/she /he/they won』t.
(三)動詞plan, come, go, leave, fly等用現在進行時表示將要發生的事.
如: I』m coming. 我就來。
He is leaving for Shanghai. 他將到上海去。
We are going to Beijing. 我們將去北京。

5. There be 句型的一般將來時
正:There will be a sports meeting in our school this weekend.
= There is going to be a sports meeting in our school this weekend.
誤:There will have a sports meeting in our school this weekend.
= There is going to have a sports meeting in our school this weekend.
四、重點語法
(一) 情態動詞: must 與 have to
① must "必須;一定」, 表示有做某一動作的必要或義務,側重表達說話者的主觀看法.(只有一種時態)如:We must wash hands before meals. 飯前我們必須洗手.
We must eat healthy food. 我們必須吃健康的食物.
② have to 「不得不,必須」, 側重表示因客觀條件或客觀環境的迫使而"不得不做某事".(可用於各種時態)
如:It』s too late. I have to go now. 太遲了.現在我得走了.
I had to borrow some money at that time. 那時我不得不借了一些錢.
*----Must we keep the windows open all the time?---No, we don』t have to. / No, we needn』t. (注意回答時不能用No, we mustn』t.)
1)Are you free this evening? = Do you have time this evening? 你今天晚上有空嗎?
三.語法學習
1.I used to listen to rock music but now I collect telephone cards and paintings. (Page 53)
我過去常聽搖滾樂,可現在我集電話卡和畫。
used to do sth. 這一結構表示過去的習慣(過去經常反復發生的動作)或狀態(暗含的意思是現在已不復存在),只有一種形式,即過去式,用於所有人稱。used to的否定形式為:used not to do或didn』t use to do。疑問句為Used you to... ? 或 Did you use to...?如:
1)I used to go to school on foot.
我過去步行上學。(暗含的意思是:我現在不再步行上學了。)
2)Mary used to sleep late.
瑪莉過去總是很晚才睡覺。(暗含的意思是:瑪莉現在睡覺不再那麼晚了。)
3)I used to walk along the road after supper.
我過去常常在晚飯後沿著這條馬路散步。
4)He used not to like Peking opera, but now he』s very fond of it.
他過去不喜歡京劇,但現在非常喜歡。
現在大多數人在口語中或不太正式的書面語中對否定句和疑問句常使用與do 連用的形式。例如:
1)I didn』t use to like skating, but now I like it very much.
我過去不喜歡滑冰,但現在很喜歡。
2)Did you use to go there?你以往常去哪兒?
3)There used to be a theatre here, didn』t there?以前這里有一座劇院,是不是?
另外,注意be used to doing sth.與used to do sth.的區別:
be used to doing sth 「習慣於…,適應於…」如:
1)He is used to working hard. 他習慣於努力地工作。2)He used to bring me roses when he came to see me. 過去他來看我時,常帶玫瑰花。
3)I』m used to doing jogging in the morning now. 我習慣於早上慢跑。
be used to do sth.「某物被用來做某事」。如:
1)Wood is used to make paper. 木材被用來生產紙張。
2)Computers can be used to do a lot of work now. 如今電腦可用來做許多事。
2. Collecting stamps must be great fun! (Page 53)集郵肯定很有趣!
must在這里是情態動詞,作用是用來表示推測,可以翻譯為「想必」。如:
1)Your brother must be in the school. I saw him just now.
你的哥哥想必在學校。我剛才看見他了。
2)Your friend must have left for Nanjing yesterday.
你的朋友想必昨天已經離開去南京了。
3) She thought that her present must be in the box.她以為禮物一定是在盒子里。
4) You must be thirsty after a long walk.走了很長的路,你一定渴了。
5) It must be ten o』clock now.現在肯定有10點鍾了。情態動詞must的三種否定形式
must表示「必須」時,其否定回答為don』t have to,意思為「不需要」。如:
1)Must I pay back the money right now? No, you don』t have to.
我必須現在償還這筆錢嗎?不,你不需要現在還。2)You must listen to the teacher carefully in class.你必須在課堂上認真聽講。
must表示「推測」時,其否定形式為can』t,意思為「不可能」。如:
1)I』ve seen what she is talking about, so she can』t be telling lies.我目睹了她所說的事情,因此,她不可能在說謊。
2)Yesterday I received a letter from him, so he can』t be here. 昨天我收到了他的信,所以說他不可能在這兒。而must not的意思為「絕對不可,不許,禁止」。如:1)You must not smoke in the hospital.你絕對不可以在醫院里吸煙。
2)You must not cross the road when the traffic lights are red.交通燈是紅色時,你千萬不能過馬路。3.He doesn』t mind whether they』re good or not. 他並不介意它們是否是好的。
此句為以whether引導的賓語從句。whether...or not「不論是否……」。如:
1)You have to get up early everyday whether it rains or not.你必須天天早點起床,不論是否下雨。2)Whether we go or not matters little.不論我們是否去,關系不大。
if與whether的區別。
二者在引導賓語從句時一般可換用。如:
1)I want to know if / whether it is going to rain tomorrow.我想知道明天是否下雨。
2) He asked me if / whether Li Ping was at home.他問我李平是否在家。3) He didn』t understand if / whether the stranger told a lie.他不明白那個陌生人是否說的是假話。
但下列幾種情況不能換用。
whether 後可緊接or not,而if一般不能。
Let me know whether or not you can come.
你能來還是不能來,請告訴我一聲。
whether引導的賓語從句可移到主句前,if則不能。如:Whether this is true or not, I can not say.這件事是否真實,我說不上。
不定式前用whether,不用if。如:I haven』t decided whether to go to the cinema or to stay at home.我還沒有決定是看電影還是留在家裡。
介詞後可用whether,不用if。如:
I haven』t settled the question of whether I』ll go back home.我是否回家還沒有定。

否定句:They weren』t watching TV while she was reading.她讀書時,他們沒在看電視。
疑問句:Was the UFO flying to us at 8 last night ?昨晚8點UFO向我們飛來了嗎?特殊疑問句:What were you drinking while we were sleeping?我們睡覺時,你們在喝什麼?
進行時態往往用在時間狀語從句中,常與when,while等連詞搭配。
(二.)be sure結構表示肯定和不肯定。be sure一般用來表示肯定,be not sure(whether/if)表示不肯定。
be sure後面可以跟不定式和賓語從句。跟不定式一般譯為「一定……」,跟賓語從句,譯為「確信……」。如:We are sure to repair the TV well. 我們一定修好這台電視機。
I』m sure you can finish your work. 我確信你能完成你的工作。Are you sure whether(if)he switched the computer on? 你確信他打開還是沒有打開電腦?
三. 語法學習
反意疑問句:由陳述句(或祈使句、感嘆句)加一個簡短問句構成的疑問句叫反意疑問
句。實質是前面陳述句的反問句。一般對應規律:前肯後否;前否後肯。即陳述部分為肯定形式,附加問句用否定形式;陳述部分為否定形式,附加問句用肯定形式。
如:There are many pyramids in Egypt,aren』t there?在埃及有許多金字塔,不是嗎?Sally visited the Great Wall last month,didn』t she?薩莉上個月參觀了長城,不是嗎?He doesn』t realize the importance of saving water,does he?他沒有意識到節約用水的重要性,是嗎?
特例點撥:①I』m your good friend,aren』t I?我是你的好朋友,不是嗎?I don』t think you can rebuild the house,can you?我認為你不能重修這座房子,是嗎?(I don』t think…主要在說think後的內容,故按從句變化)。
②陳述部分有nobody,nothing,never,no,few(沒幾個),little(幾乎沒有),hardly(幾乎不)等否定或半否定詞時,仍視為否定句。根據反意疑問句對應規律,疑問部分用肯定形式。如:There is nothing in the room,is there?屋子裡什麼也沒有,是嗎?
Maria never surports me,does she? 瑪麗亞從未支持過我,是嗎?
He had few apples,did he? 他幾乎沒有蘋果,是嗎?
③祈使句的反意疑問句:無論肯定或否定,通常在祈使句後加上will you?如:
Please close the door,will you?請關門好嗎?
Don』t tear down the old walls,will you?不要拆毀古牆,好嗎?
但以Let』s開頭的祈使句用shall we?如:
let』s make a survey,shall we?我們做個調查,好嗎?

『捌』 英語的祈使句定義

祈使句(Imperative Sentence)是英語中的一個句式,也是用於表達命令、請求、勸告、警告、禁止等回的句子。祈使答句最常用於表達命令,因此在學校文法中也常稱為命令句。

祈使句因對象(即主語)是第二人稱,所以通常都省略。祈使句的動詞都為原型,句末則使用感嘆號來表示結束。祈使句無主語 ,主語you常省去。
