Unit 20 Weird Inventions Have you ever thought about inventing something?
2
Did you worry that your idea was too strange or unrealistic?
3
Well, maybe you should think again.
4
Strange or unrealistic ideas never stopped Arthur Pedrick.
5
Pedrick was a British inventor.
6
Originally a government clerk, he spent his retirement in the 1960s and 1970s developing new and unusual ideas.
7
Some of these ideas contradicted basic physics, but that didn't stop Pedrick.
8
One of his strangest ideas was a plan to connect large tubes from the continent of Australia all the way to Antarctica, a distance of 10,000 kilometers.
9
These tubes would carry giant ice balls from Antarctica to Australia.
10
This ice would then melt in the Australian desert, and the water would be used in irrigation.
11
Another of Pedrick's inventions was a radio-controlled golf ball.
12
A golfer could change the speed and direction of the golf ball by small flaps, controlled by computer chips.
13
Using radio waves, the golfer could also find lost golf balls.
14
Arthur Pedrick had thousands of bizarre ideas for inventions, most of which were never built.
15
Though many of Pedrick's inventions were never developed, a lot of other strange ideas were.
16
In 1989, a company designed and sold a theft prevention device for expensive cars.
17
As part of this device, several tubes were attached to the bottom of a car.
18
If someone tried to steal the car, super hot flames would come out of the tubes and burn the car thief.
19
Some people who were not thieves, however, were seriously injured.
20
They accidentally set off the device by walking past the car.
21
Other strange inventions include underwear for dogs and pens with drinkable ink.
22
The underwear keeps dogs from making a mess when they go out for a walk.
23
Also, if you are ever thirsty during a test, a pen with drinkable ink would be very handy.
24
If you have an idea that seems a little out in left field, don't let that stop you from trying it.
25
You'll be in good company.
26
Listening.
27
I didn't know that.
28
Listen to the dialogue and complete each sentence.
29
Have you ever heard of Thomas Edison?
30
Of course I have.
31
Didn't he invent the light bulb?
32
Actually, he didn't invent it.
33
He just made it practical to use.
34
Really?
35
Yes, but he did invent many other things.
36
He invented the first movie camera and record player, for example.
37
So without him, we wouldn't have movies or recorded music.
38
That's right, or electric companies or batteries.
39
Wow!

值得反复跟读的句子

视频中简短而完整的句子，可以直接用在日常对话里：

  • Did you worry that your idea was too strange or unrealistic?
  • You'll be in good company.
  • Didn't he invent the light bulb?

需要注意的发音

说话人用了 7 次缩略和弱读形式，例如 didn't, don't, wouldn't。请按听到的简短形式来说。

  • “th” 音: thief /ˈθiːf/, thirsty /ˈθɝs.ti/, theft /θɛft/
  • “sh” 和 “zh” 音: invention /ɪnˈvɛnʃən/, irrigation /ˌɪɹəˈɡeɪʃən/, prevention /pɹɪˈvɛnʃən/
  • 长单词——注意重音位置: irrigation /ˌɪɹəˈɡeɪʃən/, accidentally /ˌæk.sɪˈdɛnt(ə)li/

中文母语者容易读错的音：

  • /v/ — 不要读成 /w/，上齿轻触下唇: invent /ɪnˈvɛnt/, invention /ɪnˈvɛnʃən/, inventor /ɪnˈvɛntɚ/, prevention /pɹɪˈvɛnʃən/
  • 词尾辅音 — 要读清楚，后面不要加元音: invent /ɪnˈvɛnt/, thief /ˈθiːf/, contradict /ˌkɑn.tɹəˈdɪkt/, bulb /ˈbʌlb/, attach /əˈtæt͡ʃ/
  • /r/ 和 /l/ 的区别: drinkable /ˈdɹɪŋk.ə.bəl/, golfer /ˈɡɒlfə(ɹ)/

如何用这段视频练习

  1. 先完整听一遍视频，不要开口，记下不认识的单词。
  2. 用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
  3. 录下自己的声音并与原声对比，特别注意 invent, invention, drinkable 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
