I will have finished this work.%D%A〔正〕 By the end of next week. I will have finished this work.%D%A〔析〕 by 引起的时间状语表示了动作的截止点,其意思为"不迟于某一时刻将工作做完",所以主句一般是完成时态.当然可以有将来时态,如：I'll be there by five o'clock.而till则表达其一动作一直持续到某一时刻,但句中的动词一定要用持续性动词,而瞬间的截止性动词应用其否定句式,如：I won't finish this work till(until) next weekend.%D%A〔误〕 He came to London before last weekend.%D%A〔正〕 He had come to London before last weekend.%D%A〔正〕 He came to London two weeks ago.%D%A〔析〕 before 一般要与完成时连用,而ago则与一般过去时连用.%D%A〔误〕 I have studied English for three years gince I had come here.%D%A〔正〕 I have studied English for three years since I came here.%D%A〔析〕 since用来表达主句动作的开始时间,所以其引出的从句中应为过去时,而不能用完成时态%D%A〔误〕 I can help you repair this bike. You will get it after two hours.%D%A〔正〕 I can help you repair this bike. You will get it in two hours.%D%A〔析〕 中文经常讲两小时之后来取,两天内会修好,而这个介词在英文中要用in而不要用after.其原因有二,①after 多用于过去时,如：I arrived in New York. After three days, I found a job in the bank. ② after 加时间是表达一个不确定的时间范围,如：after three days, 即三天之后的哪一天都可以.所以在许诺若干时间内会完成某事时,一定要用介词in.%D%A〔误〕 Three days after he died.%D%A〔正〕 After three days he died.%D%A〔正〕 Three days later he died.%D%A〔析〕 after 与 later都可以用来表达一段时间之后,但它们所处的位置不同,after 在时间词前,而later在时间词后.%D%A〔误〕 She hid herself after the tree.%D%A〔正〕 She hid herself behind the tree.%D%A〔析〕 after多用来表达某动作之后,所以有的语法书中称它为动态介词,如：I run after him. After finishing my homework, I went to see a film. 而behind则多用于静态事物之后.%D%A〔误〕 There is a beautiful bird on the tree.%D%A〔正〕 There is a beautiful bird in the tree.%D%A〔析〕 树上长出的果实,树叶要用on, 而其他外来的人、物体均要用in the tree.%D%A〔误〕 Shanghai is on the east of China.%D%A〔正〕 Shanghai is in the east of China.%D%A〔析〕 在表达地理位置时有3个介词：in, on, to. in表示在某范围之内; on表示与某地区接壤；to则表示不相接.如：Japan is to the east of China. %D%A〔误〕 I arrived at New York on July 2nd.%D%A〔正〕 I arrived in New York on July 2nd.%D%A〔析〕 at用来表达较小的地方,而in用来表达较大的地方.at常用于at the school gate, at home, at a bus stop, at the station, at the cinema, at a small village.%D%A〔误〕 He lived in No. 3 Beijing Road.%D%A〔正〕 He lived at No. 3 Beijing Road.%D%A〔析〕 在门牌号码前要用at, 并要注意它的惯用法：at the end of the street, at the foot of the mountain, at the top of the page.%D%A〔误〕 There is a colour TV set at the corner of the hall.%D%A〔正〕 There is a colour TV set in the corner of the hall.%D%A〔析〕 在屋内的角落应用in,而墙的外角用at,如：There is a tree at the corner of the street.%D%A〔误〕 This weekend I'll stay in Uncle Wang's.%D%A〔正〕 This weekend I'll stay at Uncle Wang's.%D%A〔析〕 要注意英文的特殊表达法,如：at a tailor's shop (裁缝店)＝at a tailor's, at the doctor's (去看病) at the bookseller's (在书店) at uncle Wang's (在王叔叔家)%D%A〔误〕 Do you know there is some good news on today's newspaper?%D%A〔正〕 Do you know there is some good news in today's newspaper?%D%A〔析〕 在报纸上的新闻要用in, 而在具体某一版上,或某一页上则要用on.%D%A〔误〕 The school will begin on September 1st.%D%A〔正〕 School will begin on September 1st.%D%A〔析〕 这里的school应看作不可数名词泛指学校的课程,即开学之意.要注意,有些活动场所当表达正在从事该种活动时不要加冠词,如：at table (吃饭), When I came to Tom's home, they were at table. 还有： at desk (学习),at work (工作) at school (上学), in hospital (住医院) at church 作礼拜如加上定冠词则另有他意,如：at the school 即在学校工作或办事,in the hospital 即在医院工作或去看望病人.%D%A〔误〕 In my way to the station, I bought a newspaper to kill time.%D%A〔正〕 On my way to the station, I bought a newspaper to kill time.%D%A〔析〕 译文为：在去车站的路上我买了份报纸,为的是消磨时光"在……的路上"应用on one's way….而 in the way 有挡道之意,如：Please move the chair it is in the way.
