篇三：名词weekday与weekend的用法与搭1
名词weekday与weekend的用法与搭配
weekend的用法与搭配
1. weekend指“周末”，在5天工作制的国家，指星期六和星期日；在6天工作制的国家，指星期日，与weekday（周日）相对，为可数名词。如：
We must go and have a weekend there. 我们应当到那里度周末。
We spend alternate weekends at our country cottage. 我们每隔一周到我们的乡间住宅过一次周末。
2. 表示“在周末”，英语可用 at [on] the weekend或at [on] weekends（用介词 at 为英国英语，用 on 为美国英语），但习惯上不说 in the weekend 或 in weekends。一般是on the weekend 表示一个星期，这个星期（有特殊性），on weekends 表示许多星期（表经常性）on weekends----在每个周末1.at weekend指通常情况下泛指的
2.on weekend指具体一个周末 例如一个人在几个月前说他那一周末干什么
3.the是特指具体的一个，at the weekend和on the weekend是一样的意思，通常用at the weekend（at the weekends也可以）
4.on weekends指的是一件事要在几个或很多个周末做
如果是某个特定周末，用定冠词+单数the weekend，否则不用定冠词但必须是复数weekends。
如：
We usually do our shopping at the weekend. 我们通常利用周末采购物品。 They like to go ballooning on the weekend. 他们周末喜欢乘气球玩。
Traffic on the roads is heaviest at weekends. 周末的交通最为繁忙。
The library is closed on weekends. 周末图书馆关门。
在美国英语中可省略其前的介词，即把weekends用作副词。如：
He works weekends. 他周末工作。
I go yachting most weekends in the summer. 在夏天，我大多数周末都乘快艇游玩。 若不是表示“在周末”，则可根据情况与其他介词搭配。如：
The weather ought to improve after the weekend. 过了周末天气应当好起来。 Tom is always going away for weekends. 汤姆每个周末总是外出。
Why don’t you and I go away for the weekend? 咱们俩何不到外地去度周末呢? The weather is stormy and will remain so over the weekend. 今天是暴风雨天气，整个周末都会是这样。
Could you oblige me with five pounds until the weekend? 能借我5英镑吗，周末还你?
3. 当weekend与this, that, last, next, every等搭配时，其前不用介词at或on。如： We are expecting guests this weekend. 我们本周末要来客人。
Accidents due to driving at high speed were very common that weekend. 在那个周末因高速驾驶造成的交通事故很多。
Tomorrow’s difficult. I’d rather yon came next weekend. 明天有困难，我希望你下周末来。
Peggy was pretty rude to my family last weekend. 佩吉上个周末对我家人很不礼貌。 We go boating on the lake every weekend. 我们每个周末都到湖上划船。
weekday的用法与搭配
1. weekday指“周日”，在5天工作制的国家，指星期一至星期五；在6天工作制的国家，指星期一至星期六，与weekend（周末）相对，为可数名词。如：
Weekdays are always busy here. 这里除周末外每天都很忙。
My weekend was boring—I just floated about (the house) or watched TV. 我的周末过得很无聊——只是在屋子里 转转或者看看电视。
2. 表示在周日，英语通常用on weekdays。如：
I’m busy on weekdays. 我除星期天外都很忙。
The library is open on weekdays only. 这个图书馆星期一至星期六都开放。
在美国英语中可省略其前的介词，即把weekdays用作副词。如：
Jane works weekdays from 10:00 a.m. to 6:00 p.m. 除星期天外简每天从上午10点工作到下午6点。
注意，表示在周末，英语可用at [on] weekends或at [on] the weekend等，但表示在周日，英语通常只用on weekdays，习惯上不用at weekdays, at the weekday等。

〔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)
〔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。
〔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.
〔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。
〔误〕 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
〔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. 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。
〔误〕 Three days after he died.
〔正〕 After three days he died.
〔正〕 Three days later he died.
〔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。
〔误〕 She hid herself after the tree.
〔正〕 She hid herself behind the tree.
〔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。
〔误〕 There is a beautiful bird on the tree.
〔正〕 There is a beautiful bird in the tree.
〔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. 〔误〕 Shanghai is on the east of China.
〔正〕 Shanghai is in the east of China.
〔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. 〔误〕 I arrived at New York on July 2nd.
〔正〕 I arrived in New York on July 2nd.
〔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。
〔误〕 He lived in No. 3 Beijing Road.
〔正〕 He lived at No. 3 Beijing Road.
〔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。
〔误〕 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.
〔误〕 This weekend I'll stay in Uncle Wang's.
〔正〕 This weekend I'll stay at Uncle Wang's.
〔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)
〔误〕 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。 〔误〕 The school will begin on September 1st.
〔正〕 School will begin on September 1st.
〔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。
〔误〕 In my way to the station, I bought a newspaper to kill time. 〔正〕 On my way to the station, I bought a newspaper to kill time. 〔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。
