(一) 翻译以下句子

（二）知识导学
主动语态和被动语态
1.在英语中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被动语态表示主语是动作的承受者。 eg: Many people speak English.(主动语态)
English is spoken by many people.(被动语态)
2．一般现在时被动语态的构成当谓语是一般现在时的时候被动语态由"be (am, is, are)及物动词的过去分词”构成。助动词“be"随人称、数的变化而改变。
Eg.This knife is made of wood and metal. Bananas are produced in Hainan.
I am taken care of by my uncle.
3.被动语态的用法当说话者不知道动作的执行者或没有必要指出动作的执行者只需要强调动作的承受者时要求使用被动语态。如果需要在被动语态中指出动作的执行者时由介词by引导。 egChinese is spoken by the largest number of people in the world.全世界说中文的人最多。
4.主动语态改写成被动语态的方法将主动语态的宾语变成主语将主动语态的谓语变成被动式be+过去分词主动语态的主语变成被动句by的宾语(或省略)。如果主动语态中有两个宾语(直接 宾语和间接宾语)可以把其中任意一个变成主语。
eg: My teacher gives me a lot of books.(主动语态)
I am given a lot of books by my teacher.
A lot of books are given to me by my teacher.
