名詞:
1、英語(yǔ)名詞可分專有名詞和普通名詞兩大類:
1、專有名詞是個(gè)別的人、地、物、團(tuán)體、機(jī)構(gòu)等的專用名稱。
專有名詞如果是含有普通名詞的短語(yǔ),則必須使用定冠詞the。如:the Great Wall(長(zhǎng)城)
姓氏名如果采用復(fù)數(shù)形式,則表示該姓氏一家人(復(fù)數(shù)含義),如:the Greens( 格林一家人)。
2、普通名詞又分為可數(shù)名詞和不可數(shù)名詞。
2、英語(yǔ)可數(shù)名詞的單復(fù)數(shù):英語(yǔ)可數(shù)名詞有單數(shù)和復(fù)數(shù)兩種形式。
1hero→heroes, photo→photos, piano→pianos.
不可數(shù)名詞一般沒(méi)有復(fù)數(shù)形式,說(shuō)明其數(shù)量時(shí),要用有關(guān)計(jì)量名詞。一盒牛奶:
3、名詞所有格:
1、 名詞所有格如:Childern’s Day(兒童節(jié)), my sister’s book(我姐姐的書)
(2)以s或es結(jié)尾的復(fù)數(shù)名詞。只在詞尾加’。如:Teachers’ Day(教師節(jié))
(3)有些表示時(shí)間、距離以及世界、國(guó)家、城鎮(zhèn)等無(wú)生命的名詞,也可在詞尾加’s. 如:
today’s newspaper(今天的報(bào)紙), ten minutes’ break(十分鐘的課間休息),
(4)無(wú)論表示有生命還是無(wú)生命的東西的名詞,一般均可用介詞of短語(yǔ)來(lái)表示所有關(guān)系。如:

② 兩人共有某物時(shí),可以采用 A and B’s 的形式,如:Lucy and Lily’s bedroom(露西和麗麗合住的臥室)
、 “of+名詞所有格/名詞性物主代詞”,稱為雙重所有格,如:a friend of my father’s(我父親的一位朋友), a friend of mine(我的一位朋友)
4、名詞或代詞作主語(yǔ)時(shí)和謂語(yǔ)之間的單復(fù)數(shù)的一致問(wèn)題:
1、謂語(yǔ)和謂語(yǔ)基本保持單復(fù)數(shù)的一致,即:主語(yǔ)是可數(shù)名詞單數(shù)或不可數(shù)名詞時(shí),謂語(yǔ)動(dòng)詞用單數(shù)形式:如:The computer was a great invention.(計(jì)算機(jī)是個(gè)了不起的發(fā)明)The water in the glass is very cold.(玻璃杯里的水很冷)
2、集體名詞(如family, class, team, group, row, police, school等)做句子主語(yǔ)時(shí),
、 如果表示整體概念,則謂語(yǔ)用單數(shù)形式,如:Class Three is a very good class.(三班是好班)
② 如果表示其中的所有成員時(shí),則謂語(yǔ)用復(fù)數(shù)形式,如:Class Three have a map of China.(三班有張中國(guó)地圖)
3、Chinese, Japanese, fish, sheep, people等表示單個(gè)時(shí)謂語(yǔ)用單數(shù),表示許多時(shí),謂語(yǔ)用復(fù)數(shù)。如:There is a sheep in the yard.(院子里有只綿羊) / There are some sheep in the yard.(院子里有一些綿羊)
4、maths, news等雖然有s結(jié)尾,但不是復(fù)數(shù),因此謂語(yǔ)仍用單數(shù):The news is very exciting. (這個(gè)消息令人興奮)
5、glasses, shoes, socks, trousers, gloves等名詞往往用復(fù)數(shù)形式,故謂語(yǔ)用復(fù)數(shù)。如:
The trousers are very cheap and I want to take them.(褲子很便宜,我想買)
6、a lot of 后跟名詞復(fù)數(shù)時(shí)謂語(yǔ)用復(fù)數(shù)形式,跟不可數(shù)名詞時(shí)謂語(yǔ)用單數(shù)形式。如:A lot of students are playing baseball now.(現(xiàn)在有許多學(xué)生在打壘球) A lot of time was wasted on that work.(大量的時(shí)間花在了那個(gè)工作上)(被動(dòng)句)
7、and 連接兩個(gè)名詞做主語(yǔ)時(shí),謂語(yǔ)原則上用復(fù)數(shù),但是兩個(gè)名詞若構(gòu)成一個(gè)整體事物時(shí),謂語(yǔ)則用單數(shù)。如:The teacher and his son are picking apples now.(老師和他的兒子在摘蘋果) / Fish and chips is very famous food. (魚和薯?xiàng)l是一種出名的食品)
8、 there be 句型中be的單復(fù)數(shù)一般由靠近的名詞決定。如:There is a table and four chairs in the room.(房間里有一張桌子和四張椅子)
9、用both…and…連接兩個(gè)事物做主語(yǔ)時(shí),謂語(yǔ)一般用復(fù)數(shù)。如:Both you and I are required to be here tomorrow.(你和我明天要求都來(lái))
10、主語(yǔ)中含有with的短語(yǔ)時(shí),謂語(yǔ)單復(fù)數(shù)由with之前的人物決定。如:A woman with a 7-year-old child was standing at the side of the road. (一名婦女帶著一個(gè)七歲的孩子(當(dāng)時(shí))就站在路邊)
11、either…or…或者 neither…nor…連接兩個(gè)人物做句子主語(yǔ)時(shí),謂語(yǔ)采用就近原則。如:Either you or he is right.(要么是你對(duì),要么是他對(duì)。/你和他有一個(gè)人是對(duì)的) / Neither you nor I am going there.(你和我都不打算去那里)
12、表示一段時(shí)間或長(zhǎng)度概念的復(fù)數(shù)名詞做主語(yǔ)時(shí),謂語(yǔ)一般用單數(shù)。如:Two months is not a short time.(兩個(gè)月不是個(gè)短時(shí)間)Two thousand kilometers is quite a long distance(距離).(兩千千米是相當(dāng)長(zhǎng)的一段距離)
13、主語(yǔ)中含有half of… / (three quarters)of… / all (of) the ….等詞語(yǔ)時(shí),謂語(yǔ)的單復(fù)數(shù)由名詞確定,如:Over three quarters of the information on the Internet is in English. / A third of the students were playing near the lake.(學(xué)生的三分之一(當(dāng)時(shí))正在湖邊玩耍) / All of the water in these rivers has been polluted.(這些河流中的水已經(jīng)被污染了)(被動(dòng)句)

時(shí)態(tài)一致是英語(yǔ)四、六級(jí)考試的一個(gè)重要內(nèi)容。通常應(yīng)由主句謂語(yǔ)的時(shí)態(tài)決定從句的謂語(yǔ)時(shí)態(tài)。一般原則是:
1、當(dāng)主句謂語(yǔ)使用現(xiàn)在時(shí)或?qū)?lái)時(shí),從句的謂語(yǔ)根據(jù)具體情況使用任何時(shí)態(tài)
He says that he lives in Wuhan.
We hope that there will be many people at your party today.
“Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.”
“There’s a lot of excitement on the street.”
“There certainly is. Do you suppose the astronauts have returned?”
2、當(dāng)主句謂語(yǔ)使用過(guò)去時(shí)的時(shí)候,從句的謂語(yǔ)必須使用過(guò)去范圍的時(shí)態(tài)
He said he was writing a novel.
The teacher wanted to know when we would finish the experiment.
He said his father had been an engineer.
3、當(dāng)從句是表示沒(méi)有時(shí)間概念的真理時(shí),從句的謂語(yǔ)應(yīng)使用一般現(xiàn)在時(shí)。例如:
The teacher told them since light travels faster than sound, lightning appears to go before thunder.
注:在此種情況下,即使主句謂語(yǔ)用了過(guò)去式的各種時(shí)態(tài),從句謂語(yǔ)也應(yīng)用一般現(xiàn)在時(shí)。
4、從句謂語(yǔ)只能用虛擬語(yǔ)氣的情況
利用時(shí)態(tài)一致原則確定從句動(dòng)詞時(shí)態(tài)時(shí),還應(yīng)注意,若主語(yǔ)動(dòng)詞是表示命令、請(qǐng)求、要求、建議、勸告等的動(dòng)詞,從句謂語(yǔ)只能用虛擬語(yǔ)氣,不能遵循時(shí)態(tài)一致原則。例如:
We insisted that we do it ourselves.
五、動(dòng)詞的語(yǔ)態(tài)
語(yǔ)態(tài)也是動(dòng)詞的一種形式,英語(yǔ)有兩種語(yǔ)態(tài):主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài)。主動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的執(zhí)行者,而被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的承受者。
1)We use electricity to run machines. (主動(dòng)語(yǔ)態(tài))
2)Electricity is used to run machines. (被動(dòng)語(yǔ)態(tài))
1.不能用于被動(dòng)語(yǔ)態(tài)的動(dòng)詞和短語(yǔ)
(1)在英語(yǔ)中,不及物動(dòng)詞不能用于被動(dòng)語(yǔ)態(tài),但有些不及物動(dòng)詞(包括短語(yǔ))容易引起誤用。如:appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。
(2)某些表示狀態(tài)或特征的及物動(dòng)詞,如:become, contain, cost, fit, have, resemble, suit也沒(méi)有被動(dòng)語(yǔ)態(tài)。
2.被動(dòng)語(yǔ)態(tài)的時(shí)態(tài)形式
常用的被動(dòng)語(yǔ)態(tài)有表1所列的幾種時(shí)態(tài)形式。
SPAN> 一般時(shí) 進(jìn)行時(shí) 完成時(shí)
現(xiàn)在 am asked am being asked
is asked is being asked
are asked are being asked
過(guò)去
was be asked was being asked
were be asked were being asked
將來(lái) shall be asked shall have been asked
will be asked will have been asked
過(guò)去 should be asked should have been asked
將來(lái) would be asked would have been asked
3.短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài)
短語(yǔ)動(dòng)詞轉(zhuǎn)換為被動(dòng)語(yǔ)態(tài)時(shí),通常被看作是一個(gè)動(dòng)詞,后面的介詞或副詞不能拆開或省略。例如:
1)So far no correct conclusion has arrived at.
2)All the rubbish should be got rid of.
4.“get + -ed分詞”的被動(dòng)語(yǔ)態(tài)
“get + -ed分詞”結(jié)構(gòu)強(qiáng)調(diào)動(dòng)作的結(jié)果,而非動(dòng)作本身,常用來(lái)表示突發(fā)性的,出乎意料的偶然事件。例如:
The boy got hurt on his way home from work.
另外,“get + -ed分詞”還可用于談?wù)摓樽约鹤龅氖拢侵鲃?dòng)的行為而不是被動(dòng)的行為。例如:
get dressed(穿衣服) get divorced(離婚)
get engaged(訂婚) get confused(迷惑不解)
get lost(迷路) get washed(洗臉)
get married(結(jié)婚)
5.能帶兩個(gè)賓語(yǔ)和復(fù)合賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)
(1)能帶兩個(gè)賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)時(shí),一次只能由一個(gè)賓語(yǔ)作主語(yǔ),另一個(gè)賓語(yǔ)被保留下來(lái)。例如:
1)We showed the visitors our new products.(主動(dòng)語(yǔ)態(tài))
2)The visitors were shown our new products.(被動(dòng)語(yǔ)態(tài))
3)Our new products were shown to the visitors.(被動(dòng)語(yǔ)態(tài))
(2)能帶復(fù)合賓語(yǔ)的動(dòng)詞改為被動(dòng)語(yǔ)態(tài)時(shí),原來(lái)的賓語(yǔ)補(bǔ)足語(yǔ)變?yōu)橹髡Z(yǔ)補(bǔ)足語(yǔ)。例如:
1)The teacher appointed him League secretary.(主動(dòng)語(yǔ)態(tài))
2)He was appointed League secretary.(被動(dòng)語(yǔ)態(tài))
6.被動(dòng)語(yǔ)態(tài)與系表結(jié)構(gòu)的區(qū)別
(1)The novel was well written.(系表結(jié)構(gòu))
(2)The novel was written by Diskens.(被動(dòng)語(yǔ)態(tài))
7.少數(shù)動(dòng)詞的主動(dòng)語(yǔ)態(tài)有時(shí)有被動(dòng)的意思
例1:The book is selling remarkably well.
例2:The song sounds very beautiful.
能這樣用的動(dòng)詞還有read(讀起來(lái)),clean(擦起來(lái)),wash(洗起來(lái)),write(寫起來(lái))。
例3:My watch needs cleaning. (= My watch needs to be cleaned).
能像need這樣用的動(dòng)詞還有:want, require, deserve, do, owe, bind等。
例4:The meat is cooking.
例5:The book written by the professor is printing.

實(shí)義動(dòng)詞與非實(shí)義動(dòng)詞
根據(jù)其含義和句子功用,動(dòng)詞可分為實(shí)義動(dòng)詞和非實(shí)義動(dòng)詞(包括時(shí)態(tài)助動(dòng)詞和情態(tài)助動(dòng)詞等)。如:
He bought a story book. 他買了一本故事書。(buy 為實(shí)義動(dòng)詞)
He has read the story book. 他已讀過(guò)這本故事書。(has 為時(shí)態(tài)助動(dòng)詞,read為實(shí)意動(dòng)詞)
He should read the story book. 他應(yīng)該讀讀這本故事書。(should 為情態(tài)助動(dòng)詞,red為實(shí)義動(dòng)詞)
上面對(duì)實(shí)義動(dòng)詞與非實(shí)義動(dòng)詞知識(shí)的內(nèi)容講解學(xué)習(xí),相信同學(xué)們已經(jīng)能很好的掌握了吧,希望同學(xué)們考試成功。

初中英語(yǔ)語(yǔ)法總結(jié)5
【一般過(guò)去時(shí)用法的】一般過(guò)去時(shí)表示在過(guò)去確定的時(shí)間里所發(fā)生的動(dòng)作或存在的狀態(tài)或者是在過(guò)去一段時(shí)間內(nèi)經(jīng)常性或習(xí)慣性的動(dòng)作。
1)在確定的過(guò)去時(shí)間里所發(fā)生的動(dòng)作或存在的狀態(tài)。
時(shí)間狀語(yǔ)有:yesterday, last week, an hour ago, the other day, in 1982等。
Where did you go just now?
2)表示在過(guò)去一段時(shí)間內(nèi),經(jīng)常性或習(xí)慣性的動(dòng)作。
When I was a child, I often played football in the street.
Whenever the Browns went during their visit, they were given a warm welcome.
3)句型:
It is time for sb. to do sth "到……時(shí)間了" "該……了"
It is time sb. did sth. "時(shí)間已遲了" "早該……了"

比較:
一般過(guò)去時(shí)表示的動(dòng)作或狀態(tài)都已成為過(guò)去,現(xiàn)已不復(fù)存在。
Christine was an invalid all her life.
(含義:她已不在人間。)

(含義:她現(xiàn)在還活著)
Mrs. Darby lived in Kentucky for seven years.
(含義:達(dá)比太太已不再住在肯塔基州。)
Mrs. Darby has lived in Kentucky for seven years.
( 含義:現(xiàn)在還住在肯塔基州,有可能指剛離去)

1)動(dòng)詞want, hope, wonder, think, intend 等。
Did you want anything else?
I wondered if you could help me.
2)情態(tài)動(dòng)詞 could, would.
Could you lend me your bike?
一般過(guò)去式與一般現(xiàn)在時(shí)所表示的很相像,但一個(gè)表示過(guò)去,一個(gè)表示的是現(xiàn)在所發(fā)生的。
初中英語(yǔ)語(yǔ)法總結(jié)6
【need】didnt need to do的意思是過(guò)去不必做某事, 事實(shí)上也沒(méi)做。而neednt have done則表示過(guò)去不必做某事, 但事實(shí)上做了。
初中英語(yǔ)語(yǔ)法大全:need "不必做"和"本不該做"
didnt need to do表示: 過(guò)去不必做某事, 事實(shí)上也沒(méi)做。.
neednt have done表示: 過(guò)去不必做某事, 但事實(shí)上做了。
John went to the station with the car to meet Mary, so she didnt need to walk back home. 約翰開車去車站接瑪麗,所以她不必步行回家了。
John went to the station with the car to meet Mary, so she neednt have walked back home. 約翰開車去車站接瑪麗,所以她本不必步行回家了。 (Mary步行回家,沒(méi)有遇上John的車。)
典型例題
There was plenty of time. She ___.
A. mustnt have hurried B. couldnt have hurried C. must not hurry D. neednt have hurried
答案D。neednt have done. 意為 "本不必",即已經(jīng)做了某事,而時(shí)實(shí)際上不必要。
Mustnt have done 用法不正確,對(duì)過(guò)去發(fā)生的事情進(jìn)行否定性推斷應(yīng)為couldnt have done, "不可能已經(jīng)"。 must not do 不可以(用于一般現(xiàn)在時(shí))。
