又如：I think the TV was invented after the car.我认为电视是在汽车之后发明的。
2、When was the telephone invented?是什么时候被发明的？was invented被发明，因“发明”这个动作是发生在过去，用一般过去时的被动语态was + invented。

例如：It is used for scooping the icecream.它杯用来舀冰激凌。

【语法归纳】
被动语态
（1）被动语态表示句子的主语是谓语动词所表示的动作承受者。
（2）被动语态基本结构：be+及物动词的过去分词（如果是不及物动词，其过去分词应带有相应的介词）
（3）被动语态中的be 是助动词，有人称、数和时态的变化。
一般现在时的被动语态为：am/is/are+过去分词
一般过去时的被动语态为：was/were+ 过去分词
与情态动词连用的被动语态：情态动词+ be + 过去分词（关于被动语态，大家一定要熟悉，这个在中考的时候属于是必考内容，而且是重点内容）（4）被动语态中动作的发出者或执行者做介词by的宾语，放在句末，by 表示“由，被”的意思，如何理解被动语态？
为了更清晰、更深刻地理解被动语态的含义，可以将主动语态和被动语态的句子结构进行比较。
主动语态：主语+谓语动词+宾语+其他成分
被动语态：主语+be+过去分词+by+宾语+其他成分
如：Many people speak English.
被动语态:English is spoken by many people.

Computer
Computers are becoming more and more important in our daily life. Do you know when the computer was invented ?
The computer was invented in 1946. At that time , it was huge. With the development of science and technology, the computer has grown smaller. Now there are many kinds of computers, such as personal computers and laptops. The computer is a very useful tool in our life.
For example , it can send some messages to foreign friends by e-mail. What's more , it can share information with others through the World Wide Web. We can also listen to music or play the game on computers. It makes us relax.
It’s hard to imagine what our life would be like without computers. I think computers will be more convenient and they are going to change our life completely in the near future.。
