Step 5　问题探究
1．含有情态动词的被动语态
教室应该被我们打扫。
Theclassroom_should_be_cleaned_by_us.
①含有情态动词的被动语态的结构为：主语(动作接受者)＋情态动词＋be＋动词的过去分词＋(by＋动作执行者)。
②被动语态的否定句：主语＋情态动词＋be＋not＋过去分词＋(by＋动作执行者)
③一般疑问句：情态动词＋主语＋be＋动词的过去分词＋(by＋动作执行者)?
④特殊疑问句：特殊疑问词＋主语＋be＋过去分词＋(by＋动作执行者)?
(　)2.—Should a teenager ________ a driving license?
—Yes，they should first go to a training centre.
A．be allow to get 　　B．allow getting
C．be allowed to get 　　D．allowed to get
答案选择C。含有情态动词的被动语态的构成：情态动词＋be＋及物动词的过去分词；又因为： be allowed to do sth.意为“被允许做某事”。所以答案选择C。
(　)3.Sixteen­year­olds should be allowed to get their ears ________.
A．pierced 　　B．pierce
C．to pierce 　　D．piercing
答案选择A。句意：应该允许十六岁的青少年打耳洞。get their ears pierced意为“打耳洞”，此处get用作使役动词，相当于make或have，意为“使；让”。“get/ have ＋宾语＋动词的过去分词”结构意为“使某事被做”或“让某人做某事”。其中过去分词表示的动作往往是被别人做的，与句中的主语无关。所以选择A。

请学生们做前面课时训练部分。
