Unit 6
Section A
1b Listen and match the inventions with the years.
Alice: Was your life very difficult when you were a kid?
Grandma: Oh, not really. Why?
Alice: Well, you didn’t have modern inventions like a telephone, right?
Grandma: Of course we did! How old do you think I am? The telephone was invented in 1876. You need to take a history class, Alice!
Alice: Haha! How about cars? They weren’t invented yet, were they?
Grandma: Yes, they were. Cars were invented in 1885. My family had a car.
Alice: Well, did you have a TV?
Grandma: No, we couldn’t afford one. They were expensive in those days. The TV was invented around 1927, I think.
Alice: Well, I know that you didn’t have a computer because we learned in school that personal computers were invented in 1976.
Grandma: You’re right. But I have one now!
1b 听录音，把发明和年份搭配起来。
艾丽斯：你小时候生活很难吗？
奶奶：哦，不是很难。怎么了？
艾丽斯：噢，你们没有像电话这样的现代发明，对吗？
奶奶：我们当然有！你认为我有多老？电话是在1876年发明的。你要上历史课了，艾丽斯！
艾丽斯：哈哈！那么汽车呢？它们还没有发明，对吗？
奶奶：不，发明了。汽车是在1885年发明的。我家里有一辆汽车。
艾丽斯：好吧，你们有电视机吗？
奶奶：没有。我们买不起。它们在那个时代很贵。我想电视机是在大约1927年发明的。
艾丽斯：嗯，我知道你们没有电脑，因为我们在学校里学过个人电脑是在1976年发明的。
奶奶：对。但现在我有一台！
2a Listen and number the inventions ［1-3］ in the order you hear them.
Alex: Hi, Carol. Wow, what are those?
Carol: Hello, Alex. Oh, these are some of the interesting inventions that I’m writing about for my English homework.
Alex: I see…What’s that, then?
Carol: They’re shoes with lights. People use them for seeing in the dark when you get up at night.
Alex: Oh, that’s a cool idea! I always hit my toe on something on the way to the bathroom at night.
Carol: Next is a special ice-cream scoop. This is my favorite invention. It runs on electricity and becomes hot.
Alex: I know what it’s for! It’s use d for serving really cold ice-cream.
Carol: Yes, that’s right! The last invention I’m going to write about is shoes with special heels. You can move the heels up and down.
Alex: What are they used for?
Carol: Well, you can change the style of your shoes. You can raise the heels if
you are going to a party or lower them if you are just going out for shopping.
2a 听录音，按你听到它们的顺序给这些发明编号［1~3］。
亚历克斯：你好，卡罗尔。哇，那些是什么？
卡罗尔：你好，亚历克斯。哦，这些是我要在英语作业中写到的一些有趣的发明。
亚历克斯：我知道了……那么，那是什么？
卡罗尔：它们是带灯的鞋。当晚上起床时，人们用它们在黑暗中看东西。
亚历克斯：哦，那是一个很酷的主意！我总是在晚上去卫生间的路上碰到脚趾。
卡罗尔：接下来是一个特别的冰激凌勺。这是我最喜爱的发明。它靠电运行，接着变热。
亚历克斯：我知道它的用途！它是用来加热非常凉的冰激凌的。
卡罗尔：是的，正确！我要写的最后一项发明是有特殊后跟的鞋。你可以上下移动后跟。
亚历克斯：它们的用途是什么？
卡罗尔：噢，你可以改变你的鞋子的风格。如果你打算参加聚会，你可以增高你的鞋跟；或者如果只是出去购物，你可以降低鞋跟。

1c Listen and CIRCLE T for true or F for false.
Boy 1: Hey, did you know that potato chips were invented by mistake?
Boy 2: Really? What do you mean?
Boy 1: Well, here on the bag it says that they were invented by a cook called George Crum.
Boy 2: When was that?
Boy 1: Oh, it was back in 1853.
Boy 2: So, why was it an accident?
Boy 1: Well, one day, a customer came into the restaurant where George worked. He ordered a plate of fried potatoes. When the potatoes came, he said they were cut too thick and sent them back to the kitchen.
Boy 2: So what happened?
Boy 1: Well, George was angry, so he cut the potatoes really, really thin, and he cooked them for a long time until they were crispy. And he put lots of salt on them so they were really salty. He thought the customer would hate them.
Boy 2: And?
Boy 1: And the customer loved them and asked for more. He told the other customers about them, and soon everyone was ordering thinly cut, crispy, salty potato chips.
Boy 2: And we’re still eating them today. What a cool story!
1c 听录音，正确的圈T,错误的圈F。
男孩1：你好，你知道炸薯片是在无意中发明的吗？
男孩2：真的吗？你的意思是什么？
男孩1：噢，这儿这个包上说它们是一个名叫乔治•克拉姆的厨师发明的。
男孩2：那是什么时候？
男孩1：哦，早在1853年。
男孩2：那么，为什么是一个意外呢？
男孩1：噢，有一天，一位顾客来到了乔治工作的饭店。他点了一盘炸土豆。当土豆端上来时，他说土豆切得太厚了，于是它们被送回了厨房。
男孩2：那么发生了什么？
男孩1：嗯，乔治很生气，因此他把土豆切得很薄很薄，然后炸了很长一段时间，直到它们很脆为止。并且他在上面撒了很多盐，因此它们很咸。他原以为那位顾客会不喜欢它们。
男孩2：然后呢？
男孩1：那位顾客很喜欢它们，并又要了一些。他告诉了别的顾客，不久大家都订购切得薄薄的、又脆又咸的炸薯片。
男孩2：今天我们还在吃炸薯片。多么酷的一个故事！
