接下来，小编为大家整理的易错题集锦，希望对大家有帮助！

1.[误]He became a writter at his twenties.    

[正]He became a writter in his twenties.[析]这句话应译为：他在20多岁时就成了作家。在某人的一段生活时间段中要用介词in来表示，而在具体岁数时用at来表示。

2.[误]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]具体某一天要用介词on,又如：on New Year’s Day

3.[误]I'm looking forward to seeing you on Christmas.   

 [正]I'm looking forward to seeing you at Christmas.[析]在节日的当天用on，而全部节日期间用at,Christmas是圣诞节期间，一般要有两周或更长的时间。

4.[误]I haven't see you during the summer holidays.    

[正]I haven't seen you since the beginning of the summer holidays.[析]during表示在某一段时间之内，所 以一般不与完成时搭配，如：I visited a lot of museums during the holiday。而for表示一段时间，可以用于完成时， 如：I haven't see you for a long time。而through用来表示时间时则为"整整，全部的时间"。 如：I trained through the night。而since则是表达主句动作的起始时间，一般要与完成时连用。

5.[误]At entering the classroom, I heard the good news. 

   [正]On entering the classroom, I heard the good news.[析]On加动名词表示"一......就"。本句的译文应是：我一进入教 室就听见这个好消息了。又如：on hearing...一听见，on arrival一到达就......(on表示动作的名词)

6.[误]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与 at the end都是指某事物的开始与结束部分，均不指时间范围，而in the beginning则是指开始一段时间。in the end＝at last是 指"最终，终于"之意。

7.[误]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。

8.[误]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一般要与完成时连用，而ago则与一般过去时连用。

9.[误]I have studied English for three years since I had come here. 

   [正]I have studied English for three yeas since I came here.[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。

10.[误]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.②after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。
