(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?
