17、w是指"借入"，其常用句型結(jié)構(gòu)是borrow something from somebody，如： i want to borrow some books from the library. 這是個(gè)瞬間性動(dòng)詞，不可與表示延續(xù)的時(shí)間狀語(yǔ)連用。lend 是"借出"，即借給別人東西。其常用句型是lend somebody something, 或lend something to somebody.如： i can lend you my bike. could you lend us your dictionary? could you lend your

18、dictionary to us? 它也是瞬間性動(dòng)詞，也不能與延續(xù)的時(shí)間狀語(yǔ)連用。keep為"借多久"，是延續(xù)性動(dòng)詞，可以和表示長(zhǎng)時(shí)間段的時(shí)間狀語(yǔ)連用，也可與how long等疑問詞連用，如： you can keep it for three days. how long can i keep it?bring, take, fetch 英語(yǔ)中bring是"帶來"，而take是"帶走"。還有一個(gè)詞fetch, 表示"到某處去把某物取、接回來"。如：please fetch the doctor at once.c

21、ll us a story? care for, care ofcare for是"對(duì)某物感興趣"，而care of是"關(guān)心，要當(dāng)心某事"，如：she didn't care for him. take care of what you are doing.change for, change with change for為"以某物為交換物"。而change with則是"隨而變"，如：the wood's colour changed with the season.cheap, low工資的高

24、裝)，a working dress(工作服)。 一般來講男套裝用suit，女服則用dress；作男服的服裝店是tailor shop (tailor's), 而做女裝的服裝店是dressmaker's. dress作及物動(dòng)詞當(dāng)"穿衣服"講時(shí)，其后不能接衣服而只能接人，如：the boy is still too young to dress himself. 但作為一種穿著打扮的狀態(tài)時(shí)，則多用其過去分詞作形容詞，如：he is not dressed in his new suit.she is dressed in red. 詞組dress up是過節(jié)日

25、時(shí)應(yīng)服裝整齊，如： they dressed up for the holiday. coffee, tea, water 雖然coffee, water, tea等都是物質(zhì)名詞，但是只有coffee可用coffees取代若干杯coffee,而其他的卻不行，其前要加a cup of或a glass e in, come into, enter come in與come into的意義相同，但come into后面要加賓語(yǔ)，而come in后面不用賓語(yǔ)。如i found someone came into my room. the door opened and the child

26、came in. enter常作為及物動(dòng)詞使用，如： the bus entered the english tunnel.in the corner, at the corner in the corner是在建筑物內(nèi)部的角上，而at the corner是在外部的角上，如： there is a big tree at the corner of the building.cost, spend. take cost, spend. take都可以作"花費(fèi)"講，但用法不同。cost的用法是"something+cost+somebody+時(shí)間或金錢"

27、，如：the book cost me ten dollars. spend的用法是"somebody+spend+時(shí)間+(in)doing something"或“somebody+spend+金錢+on something"，如：i spent two hours (in) writing this book. i spend two dollars on this book. take的用法則要用邏輯主語(yǔ)it:"it+takes+somebody+時(shí)間+to do something", 如： it took me an hour to

30、cancer is a deadly disease. dead, died dead是形容詞，如：mrs ginty was dead. died是動(dòng)詞die的過去式及過去分詞，如：she died in 1960.但英語(yǔ)中如表達(dá)出對(duì)某人去世的傷感說法是pass away, 如：my father passed away, this morning.dress, have on, put on, wear 要區(qū)別這幾個(gè)動(dòng)詞需分清是表示動(dòng)作的動(dòng)詞還是表示狀態(tài)的動(dòng)詞。表示狀態(tài)的動(dòng)詞是have on和wear，如：he has on a white coat. he was wearing hea

31、vy shoes. put on則表示穿衣的動(dòng)作，如：put on your coat, it is cold outside.dress即可以作狀態(tài)又可以作動(dòng)作，作動(dòng)作講時(shí)其后面接人而不能接衣服，作穿著狀態(tài)時(shí)則多用dressed的形式。如：i saw a lady dressed in red. i saw a girl dressing herself.drop, falldrop與fall都可以表示"落下、掉下"之意，有時(shí)可以互換，如：the dictionary fell (dropped) from the table. 但drop還可以作及物動(dòng)詞，而fall一般

32、只能作不及物動(dòng)詞。each, everyeach與every都作形容詞講時(shí)，都有"每個(gè)"之意，但有不同。each多指?jìng)€(gè)體，而every則多指整體。如：we want every student to succeed. each不用來表達(dá)總體概念，所以不能與almost, nearly, likely等詞連用。each other, one another each other與one another這兩個(gè)詞組的區(qū)別在很多語(yǔ)法書中強(qiáng)調(diào)each other是兩者之間，而one another是多者之間，其實(shí)不然，如：all students must care for each

33、 other, must love and help each other. 事實(shí)上這兩個(gè)詞組是同義的，如果要講有什么區(qū)別的話，當(dāng)我們非常籠統(tǒng)地談，而不特指什么人時(shí)，多用one another.in, on, at在講述地理位置時(shí)，有3個(gè)介詞常用，它們是in, on和to, 其中in表示處于所表達(dá)的范圍之內(nèi)，如：shanghai is in the east of china. on則表示雙方接壤，如：north korea is on the northeast of china. 表示互不相接的兩部分時(shí)則用to, 如：taiwan is to the east of fujian.fart

36、ocket with books. be filled with應(yīng)看作系表結(jié)構(gòu)，如：the boy's mother was filled with anger. full是形容詞，要用be full of這一詞組，如：the boy was full of joy.find, find out find out意為"找出、算出、發(fā)現(xiàn)"，如：i have found out how to do it. find的主要側(cè)重點(diǎn)在找到某物，如：i find my book under the desk.forget to do sth., forget doing sth

37、.要注意forget to do something為"忘了去作某事"，而forget doing something則應(yīng)譯為"對(duì)已經(jīng)作過的事記不起來了"。如：he forget returning the book to the library.他忘記已把書還給圖書館這件事了。同樣用法的詞還有remember和regret.go, comego是指離開說話人所在地，而come指的是朝向說話人的方向：如：come here! can i come and help you?但在口語(yǔ)中也有一些例外，如表示要參加到某人或者某件活動(dòng)時(shí)常用come, 如：we

38、are going to have a party tonight. would you like to come with us?gone, been he has gone to shanghai. 指此人已去上海不在此地了。he has been to shanghai. 指此人去過上?，F(xiàn)已回來了。gold, goldengold作形容詞指"金質(zhì)的"，如：a gold ring， a gold coin，golden是"金色的"，如：golden age(金色的時(shí)代)，但"金魚"例外，為gold fish。good, well

39、he is good. 他是個(gè)好人。he is well.他身體不錯(cuò)。i feel good. 我精神狀態(tài)良好，i feel well.我身體狀況不錯(cuò)。be good for是"對(duì)有利、有好處"，而be good to是指"對(duì)待某人不錯(cuò)"，如：your friend is very good to me.hear, listen to hear一詞為聽見了什么，或聽到什么，強(qiáng)調(diào)其結(jié)果；而listen to則強(qiáng)調(diào)有意要聽，聽的傾向。如：i want to listen to you, but i hear nothing.但詞組hear about (of

40、)則為"聽說過"之意，如：i heard about this. 我聽說過此事。hear from則為"收到某人信件"之意：i often hear from my girl friend.help do, help to dohelp其句型是help somebody do (to do) something. 意為"幫某人作某事"，但在較古老的語(yǔ)法中不帶to的不定式表示句子的主語(yǔ)參加這個(gè)動(dòng)作，如：he help his mother cook the meal. 他和母親一起作飯。he help me to do my homew

41、ork. 他指導(dǎo)我做作業(yè)。但在現(xiàn)代英語(yǔ)中這個(gè)區(qū)別則往往被取消了。所以帶to與不帶to的不定式在句中意思相同，并無區(qū)別。high, tall英語(yǔ)中的兩個(gè)"高"high和tall，其中tall指人指物都是可以的，但high則只指物體的高，所以可以講this building is the highest building in the city.但tall一般不用來指山脈的高低。home, house, family home是指與親人一起居住的地方，可以講a letter from home，所以有人解釋home包括住處和家人。而house的側(cè)重點(diǎn)則在建筑物，如many ne

42、w houses were built this year.family一詞，作為整體講其謂語(yǔ)動(dòng)詞用單數(shù)，如：her family is a happy one.而作為家庭成員講時(shí)要用復(fù)數(shù)謂語(yǔ)動(dòng)詞，如：my family are all like swimming.hope, withhope一詞不能接賓語(yǔ)再加上賓語(yǔ)補(bǔ)足語(yǔ)，但它可以接不定式作賓語(yǔ)，如：i hope to be a scientist.而wish卻可以接賓語(yǔ)加賓語(yǔ)補(bǔ)足語(yǔ)，如：i wish you to be a good student.in hospital, in the hospitalin hospital為"

43、住院就醫(yī)"。而in (at) the hospital 為"在醫(yī)院(工作)"。如：he is a doctor in (at) the hospital.類似的用法還有很多，如："上學(xué)"為go to school，at school為"在校就讀"，go to bed為"上床睡覺"。ill, sickill和sick都可以作表語(yǔ)，如： i'm ill (sick). 美國(guó)英語(yǔ)中常用sick，而英國(guó)英語(yǔ)中兩者都可用，但ill一般不作定語(yǔ)。interesting, interested修飾物時(shí)應(yīng)用int

44、eresting, 如，an interesting film，而講某人對(duì)某事感興趣時(shí)要用過去分詞interested，如： i'm interested in this playhe is an interesting man. .他是一個(gè)十分有趣的人。所以interesting是"令人感興趣"之意，而interested則表示某人對(duì)某事物感興趣，多用"be interested in something"這一句型。join, attend, take part injoin經(jīng)常用于參加某個(gè)團(tuán)體、政黨，并作為其中的一個(gè)成員；attend則重點(diǎn)強(qiáng)

45、調(diào)出會(huì)議、到場(chǎng)，而不一定進(jìn)行具體活動(dòng)，如： did you attend the meeting yesterday?而take part in則強(qiáng)調(diào)參與某些具體活動(dòng)或運(yùn)動(dòng)，如： i take part in the football game.just, justly just常用于三種含意： 恰好，如： it's just five o'clock. 僅僅，相當(dāng)于only, 如： i have just enough money to buy a dictionary. 不久前，如： i just missed my old friend; he left a few mi

46、nutes ago. 而justly其意為"公正的"，如： he was justly punished for his crimes. keep doing sth., keep on doing sth.keep doing something為連續(xù)不斷地做某事。有時(shí)可以與keep on doing something互換。它們的區(qū)別在于keep doing something意為該動(dòng)作一直不停地在進(jìn)行中，如： when the train started, she kept waving her hand.而keep on doing something則表示該動(dòng)作可

47、能有停頓但卻一直在進(jìn)行中，如： he kept on making the same mistakes in grammar.keep up with, keep upwe must keep up with the times.我們必須趕上時(shí)代keep up with是"趕上"之意，而keep up則是"堅(jiān)持下去"的意思，如： keep it up, don't stop now!of sth., to sth.英語(yǔ)中講某某的東西一般要用of，而key, entrance, answer則多用to，如："門的鑰匙"為key

48、to the door, "高速公路入口"為entrance to the highway, "問題的答案"為the answer (key) to the question.kind, sort, type kind和sort為同義詞，意為"種類"，而type則為"型號(hào)"，如： what type of this car do you want?(你想要這種車的什么型號(hào)?)know, know of i know him. 我很了解他。i know of him. 我聽說過他。 同樣的用法還有hear和hear

(一會(huì)見。)而latter則指按順序講的

50、后者，或靠后的，其反意詞為former，如： the former president(前總統(tǒng))。i can understand the latter part of the story. 而lately則意為"近來"、"不久前"。learn, studystudy與learn在作"學(xué)習(xí)"講時(shí)，常?？梢曰Q，但learn側(cè)重于學(xué)習(xí)成果或初級(jí)階段的模仿性學(xué)習(xí)，如：the little baby is learning to walk. 而study則多側(cè)重于學(xué)習(xí)的過程，如： i'm studying at this colle
