2017中考英語(yǔ)語(yǔ)法易錯(cuò)易混知識(shí)點(diǎn)集錦（四）

　　31. 〔誤〕 He became a writter at his twenties 〔正〕 He became a writter in his twenties

　　〔析〕這句話(huà)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(lái)表示，而在具體歲數(shù)時(shí)用at來(lái)表示。

　　32. 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 Years Day

　　33. 〔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。

　　34. 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，如：I visited a lot of museums during the holiday. 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(lái)表示時(shí)間時(shí)則為"整整，全部的時(shí)間"。如：It rained through the night.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。

　　35. 〔誤〕 At entering the classroom, I heard the good news. 〔正〕 On entering the classroom, I heard the good news. 〔析〕 On 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(tīng)見(jiàn)這個(gè)好消息了。又如：on hearing… 一聽(tīng)見(jiàn)， on arrival 一到達(dá)就……(on表示動(dòng)作的名詞)

　　36. 〔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(kāi)始與結(jié)束部分，均不指時(shí)間范圍，而in the beginning 則是指開(kāi)始一段時(shí)間。in the end＝at last是指"最終，終于"之意。

　　37. 〔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(lái)時(shí)態(tài)，如：Ill be there by five oclock.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 wont finish this work till(until) next weekend.

　　38. 〔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(guò)去時(shí)連用。

　　39. 〔誤〕I have studied English for three years gince I had come here.正 I have studied English for three years since I came here. 析 since用來(lái)表達(dá)主句動(dòng)作的開(kāi)始時(shí)間，所以其引出的從句中應(yīng)為過(guò)去時(shí)，而不能用完成時(shí)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(shí)之后來(lái)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。其原因有二，①after 多用于過(guò)去時(shí)，如：I arrived in New York. After three days, I found a job in the bank. ② 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。
