Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6:45。我在六点四十五分吃了。

(3)带有确定的过去时间状语时,要用过去时。如:
yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、
once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、
When I was 8 years old(当我八岁时…)、at+一个时间点
Did you have a party the other day?前几天,你们开了晚会了吗?
Lei Feng was a good soldier.雷锋是个好战士。
注:在谈到已死去的人的情况时,多用过去时。

(4)表示过去连续发生的动作时,要用过去时。这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。
The boy opened his eyes for a moment,looked at the captain,and then died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。

(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)
比较:
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)
Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。
(表示说话者对这一动作或行为厌烦)
I never drank wine.我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒)

(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
He used to drink alcohol.他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了)
I used to take a walk in the morning.我过去是在早晨散步。
(意味着现在不在早晨散步了)
比较:
I took a walk in the morning.我曾经在早晨散过步。
(只是说明过去这一动作)

(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)
I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)

  • 一般过去时三变技巧:
    一变:肯定句变为否定句
    技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
    I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
    技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
    I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
    技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
    The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

    二变:陈述句变为一般疑问句
    技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
    He could pack his things himself. → Could he pack his things himself?
    技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
    Mr Li looked very old. → Did Mr Li look very old?

    三变:陈述句变为特殊疑问句
    技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
    They gave the concert last night. → When did they give the concert?
    技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
    The accident happened near the station. → Where did the accident happen?

  • 考点名称:疑问代词

    • 疑问代词:
      疑问代词在句中起名词的作用,用来构成疑问句。常用的疑问代词有:   
      what, who, whose, whom, which, whatever, whichever, whoever, whomever   
      疑问代词在句中应位于谓语动词之前,没有词性和数的变化,除who之外也没有格的变化。 
      what, which, whose还可作限定词。
      Whose books are these on the desk?
      桌上的书是谁的?
      What was the directional flow of U. S. territorial expansion?
      美国的领土扩张是朝哪个方向的?
      What events led to most of the east of the Mississippi River becoming part of the United States?
      哪些事件使密西西比河以东的大部分土地归属于美国?
      疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
      指 人: who, whom, whose
      指 物: what
      既可指人又可指物: which

    • 疑问代词说明:
      一、无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:
      Which girls do you like best?
      你喜欢哪几个姑娘?
      What girls do you like best?
      你喜欢什么样的姑娘?

      二、Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
      Who(m) did you meet on the street?
      你在街上遇到了谁?(作动词宾语)
      Who(m) are you taking the book to?
      你要把这书带给谁?(作介词宾语,置句首)
      To whom did you speak on the campus?
      你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)

      三、疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
      For what do most people live and work?大部分人生活和工作的目的是什么?(旧文体)
      What are you looking for?你在找什么?(现代英语)

      四、疑问代词还可引导名词性从句,例如:
      I can't make out what he is driving at.
      我不知道他用意何在。
      Can you tell me whose is the blue shirt on the bed?
      你能告诉我床上的蓝衬衣是谁的吗?
      Much of what you say I agree with, but I cannot go all the way with you.
      你说的我大部分同意,但并不完全赞同。

    • 疑问代词用法:
      1. 疑问代词有who, whom, whose, which和what, 都是用来构成疑问句的:
      Who is calling? 谁打电话来?
      Whom do you want to speak to? 你想找谁接电话?
      作主语时用who,作宾语时用whom,在口语中用who作宾语时也不少:
      Who did you mean? 你指的是谁?
      Who are you talking about? 你们在讲谁?
      直接跟在介词后时只能用whom:
      With whom did you come? 你和谁一道来的?
      (口语中说“Who did you come with?时更多一些。)

      2. 其他三个疑问代词可用作:
      1)主语:
      What’s your address? 你的地址怎样写?
      Whose is better? 谁的好一些?
      Which of these is yours? 哪一本是你的?
      2)宾语:
      What do you mean? 你是什么意思?
      Which do you like better? 哪一个你更喜欢一些?
      Whose have you chosen? 你选了谁的?
      3)表语:
      What’s her name? 她叫什么名字?
      Whose is it? 这是谁的?
      4)定语(这样用时有些字典标作形容词):
      What time does the train leave? 这列火车什么时候离开?
      Which room shall we stay in? 我们住哪间房?
      Whose passport is this? 这是谁的护照?

    考点名称:形容词

    • 形容词
      简称adj.或a,形容词用来修饰名词或代词,表示人或事物的性质、状态,和特征的程度好坏与否,形容词在句中作定语,表语,宾语补足语。
      她是一个好学生,她学习努力。She is a good student, and she works hard.
      这辆自行车很贵。This bike is expensive.
      对不起,我现在很忙。I am sorry, I'm busy now.
      你为这次会议做好准备了吗? Have you got everything ready for the meeting?

    • 形容词的语法功能:
      一、作定语
      He is the greatest writer alive.他是依然健在的伟大的作家。
      Somewone else has done it.别人已经做了这事。
      二、作补语
      形容词做主语补足语和宾语补足语时,可以表示其现状、状态,也可以表示某一动作的结果,并常用在表示“认为,看待”的动词如believe,prove,consider等候。例如:
      The news made her sad.这消息使他感到非常悲伤。
      Don't marry young.不要早婚。
      三、作状语
      形容词或形容词短语可作状语,形容词作状语时,可以看作是“being+形容词”结构的省略,可表示时间、原因、条件、方式、强调或伴随状况等意义。例如:

    • 相关内容
    • 网友推荐
    • 图文推荐
