Unit 3 Make it happen!
Starting out & Understanding ideas
Learning Objectives
In this lesson, you will:
1.talk about inventions in our daily life.
2.learn about the process of Easton’s invention.
3.tell what you can learn from Easton.
Look at the picture and discuss the following questions.
Look and Say
What can you see in the picture
What do these things stand for
What does the picture mean to you
I can see a ladder and a light bulb. And a man is sitting on the top of the bulb and working on his laptop.
The bulb stands for new ideas and the ladder means the effort and steps.
It means that with hard work (climbing the ladder), we can make our bright ideas (the light bulb) shine.
Watch the video and answer the questions.
1 What do you know about the differences between the lives of ancient people and ours
2 What caused these differences
Starting out
Look at the pictures and answer the questions.
1 What are these inventions
2 How have they changed our lives
Si Nan / Ancient Chinese Compass

smart phone
Si Nan / Ancient Chinese Compass
It helped people find directions easily, making long-distance trips like exploring new lands or trading safer.
wheel
It made moving things and traveling faster and easier. Cars, bikes—all use wheels to help us go to places or carry loads.
computer
smart phone
It lets us work quickly, get information fast, and connect with others easily. We can study, play, and chat online, saving time and opening new ways to learn/have fun.
It puts everything in our hands—calls, messages, games, and maps. We can talk to anyone, anywhere, and do tasks (like paying bills) in seconds.
Understanding ideas
Look at the word cloud and predict what the passage is about.
design
artificial arm
invent
improve
helping hand
The passage is probably about the artificial arm, including how it is designed, invented, and improved to serve as a “helping hand” .
Read the passage and check your answer.
1 Easton LaChappelle, a 14-year-old student, stood beside his work
at a science fair. It was a robotic arm. He built it out of plastic
blocks and fishing line.
2 “Hello,” said a girl with an artificial arm, as she shook hands with Easton's work.
3 This was the first time Easton met Jenny, a girl with a special condition. She was born without an arm. Her artificial arm was just a simple hook, but it cost $80,000. What's worse, children like her grow quickly and need new arms all the time.

4 "It blew me away! I built my arm for only $300," thought Easton. "I
must lend a hand to people like her."
5 After the fair, Easton's room became a lab. He stayed there all day.
He always tried to improve his work. For his 16th birthday, Easton
got a 3-D printer. And with it, he invented an artificial arm. It was
able to move with brain signals of the user. But it wasn't good enough yet: the arm weighed 3.6 kilograms. It was too heavy for a child.

6 Easton kept working on it. He enjoyed fixing problems one after
another. And finally he hit on success at age 23. His design only
weighed 0.5 kilograms and cost around $500!
7 Easton's invention has helped many children. He didn't want to
make money from it. He decided to post his design online... for
free! People can download the design and make an artificial arm
with their own 3-D printers!
8 What a helping hand!

Think and share
1 How would Jenny's life change with Easton's invention
2 What can you learn from Easton
Learning to think for question 1
To understand the influence of something, you can compare the situation before and after the use of it.
1 How would Jenny's life change with Easton's invention
Since the design is free online, she could easily replace it as she grows, improving the comfort and quality of her life.
With Easton's invention, Jenny could get a much lighter (only 0.5 kg) and more affordable (around $500) artificial arm that moves with brain signals.
2 What can you learn from Easton
Problem-solving —He enjoyed fixing problems step by step until he succeeded.
Creativity and perseverance(毅力) —He kept improving his invention despite challenges.
Compassion(同情) —He was inspired to help others after meeting Jenny.
Selflessness —He shared his design for free instead of seeking profit.
Language Points
1. Easton LaChappelle, a 14-year-old student, stood beside his work at a science fair.
fair 在句中作名词，意为“展览会”。
例如: book fair 书展 trade fair 贸易博览会
There's a farmers' fair in the town every Saturday.
（镇上每周六有农贸市场。）
fair还可作形容词，意为“公平的；公正的；合理的”
e.g. It's not fair that he gets more money for the same work. （同样的工作他拿更多钱，这不公平。）
That's a fair price for this quality.
（就这个质量而言，价格合理。）
2. He built it out of plastic blocks and fishing line.
句中out of 意为“由……制成，用……做成”。
例如:
a toy boat carved out of wood 一只木头雕成的玩具小船
The necklace is made out of gold. 这条项链是金制的。
3. What's worse, children like her grow quickly and need new arms all the time.
what's worse意为“更糟糕的是”，用来引出一个更加糟糕或严重的情况，通常用来加重语气，强调比较。例如:
I forgot my wallet at home, and what's worse, my phone is out of power.（我把钱包忘在家里了，更糟糕的是，我的手机没电了。）
It's raining, and what's worse, I left my umbrella at home.
（天下起了雨，更糟糕的是，我把伞忘在家里了。）
blow sb. away意为“使某人大为惊讶”。例如:
The film was so good that it just blew me away.
（电影太棒了,简直让我震惊。）
Her talent for painting really blows me away.
（她的绘画天赋真的让我震撼。）
4. “It blew me away! I built my arm for only $300," thought Easton.
(1)本句是感叹句句型:what a(n) (+形容词)+单数名词! 例如:
What a nice dress!多漂亮的连衣裙啊!
What a surprise! 真是没料到的事!
(2) a helping hand意为“援手，帮助"。例如:
He’s been giving me a helping hand with the children.
