【文章內(nèi)容簡介】 完成時態(tài)。當(dāng)然可以有將來時態(tài)，如：Ill be there by five ，但句中的動詞一定要用持續(xù)性動詞，而瞬間的截止性動詞應(yīng)用其否定句式，如：I wont finish this work till(until) next weekend. 38. 〔誤〕He came to London before last weekend. 〔正〕He had e to London before last weekend. 〔正〕He came to London two weeks ago. 〔析〕before 一般要與完成時連用，而ago則與一般過去時連用。39. 〔誤〕I have studied English for three years since I had e here. 〔正〕I have studied English for three years since I came here. 析 since用來表達(dá)主句動作的開始時間，所以其引出的從句中應(yīng)為過去時，而不能用完成時態(tài)。40. 〔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)常講兩小時之后來取，兩天內(nèi)會修好，而這個介詞在英文中要用in而不要用after。其原因有二，①after 多用于過去時，如：I arrived in New York. After three days, I found a job in the bank. ② after 加時間是表達(dá)一個不確定的時間范圍，如：after three days, 即三天之后的哪一天都可以。所以在許諾若干時間內(nèi)會完成某事時，一定要用介詞in?！?1.〔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)一段時間之后，但它們所處的位置不同，after 在時間詞前，而later在時間詞后。42.〔誤〕She hid herself after the tree. 〔正〕She hid herself behind the tree.　　〔析〕after多用來表達(dá)某動作之后，所以有的語法書中稱它為動態(tài)介詞，如：I run after him. After finishing my homework, I went to see a film. 而behind則多用于靜態(tài)事物之后。43.〔誤〕There is a beautiful bird on the tree. 〔正〕There is a beautiful bird in the tree. 析〕樹上長出的果實，樹葉要用on, 而其他外來的人、物體均要用in the tree.44.〔誤〕Shanghai is on the east of China. 〔正〕Shanghai is in the east of China.　　〔析〕在表達(dá)地理位置時有3個介詞：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 to the east of China.45.〔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, at the station, at the cinema, at a small village。46.〔誤〕He lived in No. 3 Beijing Road. 〔正〕He lived at No. 3 Beijing Road.　　〔析〕在門牌號碼前要用at, 并要注意它的慣用法：at the end of the street, at the foot of the mountain, at the top of the page。47.〔誤〕There is a colour TV set at the corner of the hall. 〔正〕There is a colour TV set in 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.48. 〔誤〕Do you know there is some good news on today’s newspaper? 〔正〕Do you know there is some good news in today’s newspaper? 〔析〕在報紙上的新聞要用in, 而在具體某一版上，或某一頁上則要用on。49. 〔誤〕The school will begin on September 1st. 〔正〕School will begin on September 1st.　　 〔析〕這里的school應(yīng)看作不可數(shù)名詞泛指學(xué)校的課程，即開學(xué)之意。要注意，有些活動場所當(dāng)表達(dá)正在從事該種活動時不要加冠詞，如：at table (吃飯)， When I came to Toms home, they were at table. 還有： at desk (學(xué)習(xí))，at work (工作) at school (上學(xué))， in hospital (住醫(yī)院) at church 作禮拜如加上定冠詞則另有他意，如：at the school 即在學(xué)校工作或辦事，in the hospital 即在醫(yī)院工作或去看望病人。50. 〔誤〕Ill leave Beijing to Shanghai tomorrow. 〔正〕 Ill leave Beijing for Shanghai. 〔正〕Ill leave for Shanghai.　　〔析〕leave for 是離開某地去某處的固定搭配，不可將for改為別的介詞。這樣的搭配還有：start for 動身前往某處，set out for，sail for。51.〔誤〕Im sorry. I have to get out the bus at next stop.　　〔正〕Im sorry. I have to get out of the bus at next stop.　　〔析〕get in, 與 get out是兩個相反的詞組。get in 為上車，而get out為下車，但語法家認(rèn)為這里的in與out為副詞，所以其后不能接名詞，我們可以講Wed better get in. 或Wed better get out. 還有一組詞組有關(guān)上下車：get on/off(a train, a ship, a struck) get into/out of (a car, taxi…)52.〔誤〕Be careful The temperature of the water is ninety degrees over zero.〔正〕Be careful. The temperature of the water is ninety degrees above zero. 〔析〕 over 與 above 在作為比某物高的意思時有時可以互換。但在垂直方向上的高矮時，.53.〔誤〕The Dead Sea is under the sea level.　　〔正〕The Dead Sea is below the sea level.　　〔析〕，over與under也是反意詞。54.〔誤〕There is a big tree in the front of the house.　　〔正〕There is a big tree in front of the house.　　in front of 是在物體外部的前面，而in the front of 是在物體內(nèi)部的前面，如：The driver sits in the front of the bus.55.〔誤〕It took them two days to walk across the forest.　　〔正〕It took them two days to w
