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:系动词

    • 系动词
      亦称连系动词。作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语,亦称补语(形容词),构成系表结构说明主语的状况、性质、特征等情况。

    • 系动词的分类:
      1)状态系动词
      用来表示主语状态,只有be一词,例如:
      He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
      2)持续系动词
      用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:
      He always kept silent at meeting. 他开会时总保持沉默。
      This matter rests a mystery. 此事仍是一个谜。
      3)表像系动词
      用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
      He looks tired. 他看起来很累。
      He seems (to be) very sad. 他看起来很伤心。
      4)感官系动词
      感官系动词主要有feel, smell, sound, taste, 例如:
      This kind of cloth feels very soft.
      这种布手感很软。
      This flower smells very sweet.
      这朵花闻起来很香。
      5)变化系动词
      这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
      例如:
      He became mad after that. 自那之后,他疯了。
      She grew rich within a short time. 她没多长时间就富了。
      6)终止系动词
      表示主语已终止动作,主要有prove, turn out, 表达"证实","变成"之意,例如:
      The rumor proved false. 这谣言证实有假。
      The search proved difficult. 搜查证实很难。
      His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)

    • 系动词使用的注意事项:
      系动词本身有一定的词义,不能单独作谓语,后面必须与表语连用。复习系动词时,必须注意以下几个问题:<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

      1.be是最重要的系动词,主语不同,be的形式也不同,且有时态的变化。

      a通常表示主语的特征、状态和身份等,后面接形容词、副词、名词、介词短语、不定式、v-ing、过去分词及表语从句作表语。

      b特别要注意be+过去分词所构成的系表结构与be+过去分词所构成的被动语态的区别。

      c前者侧重于表示主语的特征或所处的状态,通常没有由by引导的介词短语。

      如:The door was closed.

      后者侧重于强调主语是谓语动词所示动作的承受者,表示动作;句中可以用由by引导的介词短语。如:The door was closed by me.

      d还要注意be+ V-ing所构成的系表结构与be+ V-ing”所构成的进行时态的区别。

      前者侧重于说明主语具有的特征或存在的状态,也可说明主语是什么。如:My job is teaching English.

      后者侧重于强调主语正在做某事。如:Mr Wang is reading an evening paper now.


      2.
      要注意由行为动词转化成的系动词。

      a表示人体感官的系动词有soundtastelookfeelsmell等,后面接形容词;

      b表示主语从一种状态转变到另一种状态的系动词有becomegetgoturnrungrowcomefallprove等,后面接形容词、名词或 to be+形容词,become后面接单数名词时,名词前要用不定冠词,turn
