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!

Grammar
1. by mistake为介词短语，意为“无意中；错误地”，
相当于accidentally。
例句：今天早上我无意中错过了校车。
I missed the school bus by mistake this
morning.
我错拿了你的钢笔。
I took your pen by mistake.
mistake还可以构成短语：
make a mistake/make mistakes 犯错误
mistake…for… 把……错认成……
翻译：别再出错了。
我把她错认成我们的英语老师了。
I mistook her for our English teacher.
Don’t make mistakes any more.
2. The customer thought the potatoes were not thin
enough.
单词enough修饰名词时，可置于名词前或后面。
如：我有足够的钱。
其修饰形容词、副词要后置。
如：He wrote carefully enough to get the award
of the competition.
I have enough money.
enough常可以和词组so-that，too-to转换。
他跑得不够快，赶不上其他人了。
He didn’t run fast enough to catch up with the others.
He ran so slowly that he couldn’t catch up with the others.
He ran too slowly to catch up with the others.
3. The customer was happy in the end.

By the end of last year we’ve made ten planes.
in the end 用一个单词表达可以是finally，用一个短语表达可以用at last 。
