(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:特殊疑问句

    • 特殊疑问句:
      以特殊疑问词开头,对句中某一成分提问的句子叫特殊疑问句。
      常用的疑问词有:what、who、whose、which、when、where、how、why等。
      特殊疑问句的基本结构是“疑问词+一般疑问句”。
      其回答应当是具体的。特殊疑问句句末一般用降调。 
      例如:How do I get there? 
                  Why not? 
                  What about the sports news?

    • 常用疑问词可先分为3种:
      疑问代词:
      what(什么)
      who(谁,作主语)
      which(哪个,在一定范围内选择)
      whose(谁的,指附属关系)
      whom(谁,作宾语)

      疑问副词:
      when(何时,询问时间)
      where(何地,询问地点)
      why(为什么,询问原因)
      how(如何,询问手段,方式,工具以及程度)

      疑问形容词:
      what(which,whose)+名词
      例词:
      what time(什么时候) what colour(什么颜色)... ...
      how much(多少) how long(多长)...

    • 特殊疑问句的特点:
      一、 特殊的疑问词:
      特殊疑问句要由疑问代词或疑问副词开头,询问的内容不同, 使用的疑问词也不同。
      我们学过的疑问词有what(询问事物), how much(询问价格), what time (询问时间,尤其是点钟), what kind of(询问种类), why(询问原因),who(询问人), where(询问地点) 等等。如:
      —What is this? 这是什么?
      —It's a key. 这是一把钥匙。
      —How much is it? 这个多少钱?
      —It's twenty dollars. 二十美元。
      —What kind of movies do you like? 你喜欢哪一类型的电影?
      —I like action movies. 我喜欢动作片。

      二、特殊的语序:
      特殊疑问句由疑问词开头,其构成是“疑问词 + 一般疑问句”。如:
      What time is it? 现在几点钟?
      Who is your teacher? 谁是你的老师?
      特殊疑问句有两种语序:
      1.如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:
      Who is singing in the room﹖
      whose bike is broken﹖
      2.如疑问词作其他成分,即对其他成分提问,其语序是:
      特殊疑问词+一般疑问句(特殊疑问词+be/助动词/情态动词+主语+谓语)
      What does she like?
      What class are you in﹖
      Where are you from﹖
      What time does he get up every morning﹖
      How do you know﹖
       
      三、特殊的答语:
      特殊疑问句不能用yes, no来回答,而应根据它所询问的内容直接做出回答才行。如:
      — What time is it, please? 请问几点了?
      — It's 7:30. 七点半了。
      — Where are they? 他们在哪儿?
      —They're in the playground. 他们在操场上。
      —What's your favorite subject? 你最喜爱的科目是什么?
      —English. 英语。

      四、 特殊的语调:
      一般情况下,特殊疑问句要用降调(↘)来读。如:
      Who's ↘that?
      How old is↘Jack?
