思考：
1) 被动语态结构有何规律？
2) 被动语态句中主语是动作的执行者还是承受者？
语态用来表示主语和谓语之间的关系。英语中有两种语态，一种是主动语态，表示主语是动作的执行者；另一种是被动语态，表示主语是动作的承受者。
被动语态
1. Kelly cleans the house every day. (该句为主动语态，主语Kelly是动作clean的执行者，宾语the house是动作clean的承受者。)
2. The house is cleaned by Kelly every day. (该句为被动语态，主语the house是动作clean的承受者，动作的执行者Kelly由介词by引出。)
被动语态通常由“助动词be+及物动词的过去分词”构成。当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者，或者只需强调动作的承受者时，要用被动语态。如：
English is spoken in many countries.
Such books were written for middle school
students.
The computer should be turned off at once.
一般现在时的被动语态
一、构成
be (am / is / are) +及物动词的过去分词
如：
The students are told to study hard.
The students aren't told to study hard.
—Are the students told to study hard
—Yes, they are. / No, they aren't.
Who are told to study hard
肯定句 否定句 一般疑问句
一般 现在时 I am asked … He/She is asked … We/You/They are asked … I am not asked… He/She is not asked… We/You/They are not asked … Am I asked …
Is he/she asked …
Are we/you /they asked …
二、如何将主动句变成被动句
分为五步：
第一步将主动句中的宾语变成被动句中的主语(宾语如为人称代词，须将宾格变为主格)；
第二步根据这个主语选用相应的助动词be (am / is /are)；
第三步将主动句中的谓语动词变成它的过去分词形式；
第四步将主动句中的主语置于介词by之后(如为人称代词，须将主格变为宾格)；
第五步将句中的其他成分加上。如：
1. Nowadays China ____ for its new “four great inventions”—shared bicycle, electronic payment, high-speed railways and online shopping.
A. was knowing B. was known
C. is knowing D. is known
D
