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(lái)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。

　　2.〔誤〕 She hid herself after the tree. 〔正〕 She hid herself behind the tree.

　　〔析〕 after多用來(lái)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 my homework, I went to see a film. 而behind則多用于靜態(tài)事物之后。

　　3.〔誤〕 There is a beautiful bird on the tree. 正〕 There is a beautiful bird in the tree.

　　〔析〕 樹(shù)上長(zhǎng)出的果實(shí)，樹(shù)葉要用on, 而其他外來(lái)的人、物體均要用in the tree.

　　4.〔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(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 to the east of China.

　　5.〔誤〕 I arrived at New York on July 2nd. 〔正〕 I arrived in New York on July 2nd.

　　〔析〕 at用來(lái)表達(dá)較小的地方，而in用來(lái)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。

　　6.〔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 the mountain, at the top of the page。

　　7.〔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.

　　8. 〔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)紙上的新聞要用in, 而在具體某一版上，或某一頁(yè)上則要用on。

　　9. 〔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(kāi)學(xué)之意。要注意，有些活動(dòng)場(chǎng)所當(dāng)表達(dá)正在從事該種活動(dòng)時(shí)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。

　　10. 〔誤〕 Ill leave Beijing to Shanghai tomorrow. 〔正〕 Ill leave Beijing for Shanghai. 〔正〕 Ill leave for Shanghai.

　　〔析〕 leave for 是離開(kāi)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(dòng)身前往某處，set out for， sail for。
