21世纪教育网
拉链的发明可追溯到19世纪末、20世纪初，有位美国退休的足球运动员贾德森，他是个头脑聪明的大胖子。那时流行穿绑鞋带的中长筒皮靴。这对他那双大脚来说实在是一件不容易的事，每天早晨他总是费了很大的功夫，才完成穿鞋的"壮举"。于是他就冥思苦想要设计一种一拉就OK的东西，他把这种东西取名为zip-fastener（用拉的纽扣）。这就是世界上第一条拉链。
Whitcomb L. Judson (1846 –1909) was an American machine salesman, mechanical engineer and inventor. He developed and invented the zipper in 1890.
Watch the video carefully and answer the questions below.
1. What is the subject for Paul’s school project
Small inventions that changed the world.
2. What kind of invention does Roy think of
The zipper.
3. Why does Roy think it is a great invention
Because it is often used in our daily lives.
4. Who was the zipper invented by
Whitcomb Judson.
5. When did the zipper become popular
Around 1917.
Listen and repeat.
Paul: Hey Roy, the subject for my school project is “Small inventions that changed the world”. Can you help me think of an invention
Roy: With pleasure! Let me think ... hmm ... I know! The zipper!
Paul: The zipper Is it really such a great invention
Roy: Think about how often it’s used in our daily lives. You can see zippers on dresses, trousers, shoes, bags ... almost everywhere!
2d
Paul: Well, you do seem to have a point ...
Roy : Of course! I thought about it because I saw a website last week. The pioneers of different inventions were listed there. For example, it mentioned that the zipper was invented by Whitcomb Judson in 1893. But at that time, it wasn’t used widely.
Paul: Really So when did it become popular
Roy : Around 1917.

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.

语法专讲
主动语态：主语是动作的执行者

1.被动语态的构成：
be+done（过去分词）
其否定形式为

注意：
2.不及物动词happen, take place没有被动语态。
如：The traffic accident happened on Monday.这个交通事故发生在周一。
3. 某些表示主语的品质和状态、自身特征的不及物动词，如cut，sell，read，write，fill，cook，lock，wash，drive，keep等，常用主动形式表示被动意义。
如：The book sells well. 这本书卖得很好。
