3、【研学析】.过去分词(短语)作定语的基本用法1.过去分词(短语)作定语的意义:(1)不及物动词的过去分词(短语)作定语,只表示动作已完成,不表示被动意义。(2)及物动词的过去分词(短语)作定语,既表示被动意义又表示完成意义,有时只表示被动意义。2.过去分词(短语)作定语的位置(1)单个的过去分词作定语一般放在被修饰的名词之前,但left只作后置定语。(2)过去分词短语作定语要放在被修饰的名词之后作后置定语,其作用相当于一个定语从句。名师解惑(1)单个的过去分词修饰复合不定代词something,everything,anything,nobody等或指示代词those等时,要放在这些词的后面。

4、(2)过去分词作定语时,及物动词的过去分词可改为动词为被动形式的定语从句。(3)不及物动词的过去分词作定语时,可改为动词为完成式的定语从句。.过去分词/现在分词/不定式作定语的区别语法形式意义时间关系过去分词作定语done表示被动意义表示被动、动作已完成现在分词作定语doing表示主动意义表示主动、动作正在进行;表示经常性的动作或现在(当时)的状态being done表示被动意义表示被动、动作正在进行不定式作定语to do表示主动意义表示主动、动作将要发生to be done表示被动意义表示被动、动作将要发生名师解惑 非谓语动词作定语是高考考查的重点,也是难点,做题的关键是:(1)一看非谓语动

5、词与其逻辑主语(即被修饰词)之间是逻辑上的主谓还是动宾关系;二看非谓语动词所表示的动作与谓语动词所表示的动作的时间关系,两者是同时进行还是非谓语动词所表示的动作已经完成或尚未发生。(2)如果是主谓关系,就用现在分词doing,表示被动就用being done;如果是动宾关系,已完成,就用过去分词done,如果动作正在进行,就用being done;如果动作尚未发生,就用to do,表示被动就用to be done。【内化用】句式转换1.I borrowed a book which/that was written by Mark Twain from the library.I borrow

8、r uncle【常温故勤总结】过去分词作定语,可分前置和后置;过去分词作定语,可表被动和完成。现在分词作定语,可表主动和进行。动词不定式作定语,可表被动和将来。非谓语动词特重要,用法区别记心中。.用括号内词的适当形式填空1.Mrs White showed her students some old maps _(borrow)from the library.2.The professor _(give)us a lecture now comes from Peking University.3.The players _(select)from the whole country are
