解题小妙招
情态动词被动妙招

情态动词加be done,否定not加在情态间:
疑问句式也不难,情态提前放句首:
综合运用看主语,承受动作用被动:
结合时态和语境,情态被动准能辨。
考法精析
考法一:情态动词被动语态基本结构及否定形式
核心:掌握情态动词被动语态的基本构成(情态动词+b叶过去分词)及否定形式(情态动词
+not+be+过去分词),并能结合语境正确运用
真题1(语法填空):
This difficult problem can-(solve)by our teacher
答案:be solved
解析:情态动词can后接动词原形,被动语态结构为“情态动词+be+过去分词”,solve的过去分
词为solved,故填be solved。
真题2(单项选择):
The children shouldn't_(allow)to swim in the river alone.It's dangerous.
A.allow
B.be allowed
C.allowed
D.be allowing
答案:B
解析:情态动词shouldn't后接动词原形,且“孩子们”与“允许”之间是被动关系,应用被动语态,
其结构为“情态动词+not+be+过去分词”,allow的过去分词为allowed,故选B。
考法二:情态动词被动语态句式转换
4
初中沪教上海版
【动词专项】
被动语态全解
核心:掌握情态动词被动语态的肯定、否定、疑问形式结构,能根据语境完成句式转换
真题1(句型转换):
This work can be finished today.(改为否定句)
答案:This work can not be finished today
解析:情态动词被动语态的否定形式为“情态动词+not+be+动词过去分词”,can的否定直接加
not,即can not。
真题2(单项选择):
-the homework be handed in today?
A Must B Must to C Must be D Must is
答案:A
解析:情态动词被动语态的疑问形式为“情态动词+主语+b+动词过去分词”,将情态动词提前,
此处用Must符合结构。
考法三:被动语态的综合运用与特殊结构
核心:结合时态与情态动词判断被动语态结构,掌握不及物动词短语被动及主动表被动的特殊用法
真题1(单项选择):
This problem-by my teacher yesterday.You don't need to worry about it now.
A.was solved B.solved C.can be solved D.is solved
答案:A
解析:主语“this problem”是动作“solve”的承受者,需用被动语态;由时间标志词“yesterday”
可知用一般过去时被动语态,结构为“was+过去分词”,solve的过去分词为solved。.
真题2(语法填空):
The old songs-(listen)to by many people these days because they bring back good memories.
答案:are listened
解析:主语“The old songs”是动作“listen to”的承受者,用被动语态;不及物动词短语“listen to”
变为被动时需保留介词to:由时间标志词“these days”可知用一般现在时被动语态,主语为复数,
be动词用are,listen的过去分词为listened。
