1 Easton LaChappelle, a 14-year-old student, stood beside his workat a science fair. It was a robotic arm. He built it out of plasticblocks and fishing line.
2 “Hello," said a girl with an artificial arm, as she shook hands withEaston's work.
3 This was the first time Easton met Jenny, a girl with a specialcondition, She was born without an arm, Her artificial arm wasjust a simple hook, but it cost $80,000. What's worse, children likeher grow quickly and need new arms all the time.
4 “It blew me away! I built my arm for only $300," thought Easton.“Imust 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 wasable 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 achild.
6 Easton kept working on iingt. He enjoyed fixing problems one afteranother, And finally he hit on success at age 23. His design onlyweighed 0.5 kilograms and cost around $500!
7 Easton's invention has helped many children. He didn't want tomake money from it. He decided to post his design online... for free! People can download the design and make an artificial armwith their own 3-D printers!

名词短语作同位语
1.Easton LaChappelle, a 14-year-old student, stood beside his work…
在一个名词(人名、地名等)后面,用逗号隔开,再写一个名词短语;作用是对前面的名词进行补充、解释身份;两个部分指的是同一个人或者同一个事物。
e.g.This was the first time Easton met Jenny, a girl with a special condition.
阅读技巧:两个逗号中间的同位语可先跳过,快速找到主语和谓语。
1.7.2013
同位语是写作加分句型。看到长句子,先把两个逗号之间的身份说明跳过,主干立刻清楚。
‹#›
a 14-year-old student, stood beside his work…
连字符连接,中间名词必须用单数:a two-hour trip
作表语时:无连字符,名词用复数
The student is 14 years old. ✓
14-years-old ❌️
1.7.2013
这是中考改错高频点。记住口诀:连字符作定语,名词用单数;be 动词后作表语,无连字符,名词用复数。考试里看到 14-years-old 直接判错。
‹#›
2.“Hello,” said a girl with(表伴随,有) an artificial arm, as she shook hands with Easton’s work (para2)
(1) with an artificial arm,介词短语做后置定语修饰a girl。
(2) as引导时间状语从句,表示当....时

2.“Hello,” said a girl with an artificial arm, as she shook hands with Easton’s work (para2)
当直接引语(对话内容)放在句首,可以把谓语动词(said, answered, shouted 等)放到主语前面,形成倒装:“引语,” + 谓语 + 主语,…
使用场景:主要用于记叙文对话描写,书面写作可以增加句式变化。 例句:“Wait!” shouted Tom. “等一下!” 汤姆大喊道。
⚠️注意:如果主语是代词(he/she),一般不进行倒装
❌ “OK,” said he.(错误)
“OK,” he said.(正确)
不在

表达出生只能用 be born,没有主动形式。
(1)be born in + 年/地点
He was born in 2002.
(2) be born on + 具体日期
She was born on June 1st.
(3) be born with sth.天生就拥有……
She was born with a good voice. 她天生一副好嗓子。
本篇是 be born without… 生来缺少……
3.The girl was born without(生来就没有,表伴随)an arm. (para 3)
1.7.2013
bear 的过去分词有两个:born 用于"出生",borne 用于其他含义。初中只需记住 be born 这个被动结构。
‹#›
4.This was the first time Easton met Jenny. (这是第一次....)
核心难点:主句 be 动词决定从句时态
This/It was the first time (that) + 主语 + 动词过去式
This/It was the first time (that) + 主语 + had + 过去分词
例句:
This was the first time I saw him.
This was the first time I had seen him.

try to do sth.尽力做某事
