5、daybreak.正 we got to the top of the mountain at day break.析 at 用于具體時(shí)刻之前，如：sunrise, midday, noon, sunset, midnight, night。誤 dont sleep at daytime正 dont sleep in daytime.析 in 要用于較長(zhǎng)的一段時(shí)間之內(nèi)，如：in the morning afternoon, 或 in the week monthyear. 或 in spring supper autumn winter 等等。誤 we visited the old man

6、in sunday afternoon.正 we visited the old man on sunday afternoon.析 in the morning, in the afternoon 如果在這兩個(gè)短語(yǔ)中加入任何修飾 詞其前面的介詞都要改為 on, 如：on a coldmorning, on the morning of july 14th誤 he became a writter at his twenties正 he became a writter in his twenties析 這句話應(yīng)譯為：他在 20 多歲時(shí)就成了作家。在某人的一段生活時(shí)間段中 要用介詞 in 來表

7、示，而在具體歲數(shù)時(shí)用 at 來表示。誤 he went to new york to find a job in sixteen years old.正 he went to new york to find a job at sixteen.析 在具體年歲前用 at, 如：at the age of 12， at your age， 等等。 誤 we went to swim in the river in a very hot day.正 we went to swim in the river on a very hot day.析 具體某一天要用介詞 on, 又如：on new yea

8、rs day誤 im looking forward to seeing you on christmas.正 im looking for ward to seeing you at christmas.析 在節(jié)日的當(dāng)天用 on，而全部節(jié)日期間用 at,christmas 是圣誕節(jié)期間， 一般要有兩周或更長(zhǎng)的時(shí)間。誤 i havent see you during the summer holidays.正 i havent seen you since the beginning of the summer holidays.析 during 表示在某一段時(shí)間之內(nèi)，所以一般不與完成時(shí)搭配，

9、如：i visited a lot of museums during theholiday. 而 for 表示一段時(shí)間，可以用于完成時(shí)，如：i havent see you for a long time. 而 through用來表示時(shí)間時(shí)則為整整，全部的時(shí)間。如：it rained through thenight. 而 since 則是表達(dá)主句動(dòng)作的起始時(shí)間，一般要與完成時(shí)連用。誤 at entering the classroom, i heard the good news.正 on entering the classroom, i heard the good news.析 on

10、 加動(dòng)名詞表示一就。本句的譯文應(yīng)是：我一進(jìn)入教室就聽見這個(gè) 好消息了。又如：on hearing 一聽見， on arrival一到達(dá)就(on 表示動(dòng)作的名詞)誤 in the beginning of the book, there are some interesting stories.正 at the beginning of the book, there are some interesting stories.析 at the begining 與 at the end 都是指某事物的開始與結(jié)束部分，均不 指時(shí)間范圍，而 in the beginning則是指開始一段時(shí)間。in

11、the endat last 是指最終，終于之意。誤 till the end of next week. i will have finished this work. 正 by the end of next week. i will have finished this work. 析 by 引起的時(shí)間狀語(yǔ)表示了動(dòng)作的截止點(diǎn)，其意思為不遲于某一時(shí)刻將工 作做完，所以主句一般是完成時(shí)態(tài)。當(dāng)然可以有將來時(shí)態(tài)，如：ill bethere by fiveoclock.而 till 則表達(dá)其一動(dòng)作一直持續(xù)到某一時(shí)刻，但句中的動(dòng)詞一定要用 持續(xù)性動(dòng)詞，而瞬間的截止性動(dòng)詞應(yīng)用其否定句式，如：i won

12、tfinish this work till(until) next weekend.誤 he came to london before last weekend.正 he had come to london before last weekend.正 he came to london two weeks ago.析 before 一般要與完成時(shí)連用，而 ago 則與一般過去時(shí)連用。誤 i have studied english for three years gince i had come here. 正 i have studied english for three years

13、 since i came here. 析 since 用來表達(dá)主句動(dòng)作的開始時(shí)間，所以其引出的從句中應(yīng)為過去 時(shí)，而不能用完成時(shí)態(tài)誤 i can help you repair this bike. you will get it after two hours.正 i can help you repair this bike. you will get it in two hours.析 中文經(jīng)常講兩小時(shí)之后來取，兩天內(nèi)會(huì)修好，而這個(gè)介詞在英文中要用 in 而不要用 after。其原因有二，after 多用于過去時(shí)，如：i arrivedin new york. after three

14、days, i found a job in the bank. after加時(shí)間是表達(dá)一個(gè)不確定的時(shí)間范圍，如：after three days, 即三天之后的哪 一天都可以。所以在許諾若干時(shí)間內(nèi)會(huì)完成某事時(shí)，一定要用介詞 in。誤 three days after he died.正 after three days he died.正 three days later he died.析 after 與 later 都可以用來表達(dá)一段時(shí)間之后，但它們所處的位置不 同，after 在時(shí)間詞前，而 later 在時(shí)間詞后。誤 she hid herself after the tree.正

15、she hid herself behind the tree.析 after 多用來表達(dá)某動(dòng)作之后，所以有的語(yǔ)法書中稱它為動(dòng)態(tài)介詞， 如：i run after him. after finishing myhomework, i went to see a film. 而 behind 則多用于靜態(tài)事物之后。誤 there is a beautiful bird on the tree.正 there is a beautiful bird in the tree.析 樹上長(zhǎng)出的果實(shí)，樹葉要用 on, 而其他外來的人、物體均要用 in the tree.誤 shanghai is on t

16、he east of china.正 shanghai is in the east of china.析 在表達(dá)地理位置時(shí)有 3 個(gè)介詞：in, on, to。 in 表示在某范圍之內(nèi); on 表示與某地區(qū)接壤；to 則表示不相接。如：japan is tothe east of china.誤 i arrived at new york on july 2nd.正 i arrived in new york on july 2nd.析 at 用來表達(dá)較小的地方，而 in 用來表達(dá)較大的地方。at 常用于 at the school gate, at home, at a bus stop,

17、at the station, at the cinema, at a small village。誤 he lived in no. 3 beijing road.正 he lived at no. 3 beijing road.析 在門牌號(hào)碼前要用 at, 并要注意它的慣用法：at the end of the street, at the foot of themountain, at the top of the page。誤 there is a colour tv set at the corner of the hall.正 there is a colour tv set in

18、 the corner of the hall.析 在屋內(nèi)的角落應(yīng)用 in，而墻的外角用 at，如：there is a tree at the corner of the street.誤 this weekend ill stay in uncle wangs.正 this weekend ill stay at uncle wangs.析 要注意英文的特殊表達(dá)法，如：at a tailors shop (裁縫店)at a tailors, at the doctors(去看病) at the booksellers (在書店) at uncle wangs (在王叔叔家)誤 do you know there is some good news on todays newspaper 正 do you know there is some good news in todays newspaper 析 在報(bào)紙上的
