主编：黄冈中学英语集体备课组
Step 1 The introduction to the text
Where can we see lots of old inventions？ In the museum. While we are visiting the museum, according to the introductions to the inventions, we know who the inventors are, what they are used for doing and when they were invented. We can’t imagine what our life is like without lights, telephones, cars or TVs. Without lights, we would live in the dark. Without telephones we couldn’t keep in touch with others in time. So they are all useful and necessary in our daily life. Thanks to the great inventors, their useful inventions make our life more wonderful and easier.

Ⅳ Grammar the passive voice 被动语态 (Ⅰ)
一、概念：英语中及物动词有两种语态，即主动语态（The Active Voice）和被动语态（The Passive Voice）。主动语态表示主语是动作的执行者（谓语动作是主语来做的），被动语态表示主语是动作的承受者（谓语动作是由宾语来做的）。
二、构成：被动语态是由“be + done(动词的过去分词)”构成的。be动词由人称、时态和单复数的变化。
三、如何判断句子是主动语态还是被动语态？
看句子的谓语部分是否有be和done。
1．I have found my pen.（主动）
2．Jane was doing her homework.（主动）
3．The tree was planted by us. （被动）
四、如何将句子从主动语态变成被动语态？
Many people visit the Great Wall every year.
第一步：找出原句的谓语动词，将它变成be+过去分词形式。visit—be visited
第二步：找出原句的宾语the Great Wall，将它放在句首（如果是人称代词，要把它变成主格）变成被动句的主语，首字母大写。
第三步：根据被动句主语的单复数来确定be动词的形式。be—is
第四步：找出原句的主语many people，将它放在谓语动词之后或者句末（如果是人称代词，要把它变成宾格），首字母小写，并在前面加上介词by。
第五步：原句中其他部分（every year）直接抄写在被动句中，不作改动。
被动句是：The Great Wall is visited by many people every year.
