Did you know potato chips were invented by mistake
Wow, I didn’t know that. Who invented them
It’s said that they were invented by a cook called George Crum.
When was that
Oh, it was back in 1853.
Why was it an accident
One day, a customer ordered a plate of fried potatoes. George cooked them for him. When the potatoes came, he said they were cut too thick and sent them back to the kitchen.
So what happened
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.
And then
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.
1. salty adj. 咸的
*The customer said they were not salty enough. 顾客说它们不够咸。
*You put too much salt in the soup and it’s too salty. 你在汤里放的盐太多, 它太咸了。
【自主归纳】 salty的用法
salty为形容词, 意为“咸的, 含盐的”, 是由“名词salt+-y”构成的形容词
【归纳拓展】 “名词+-y”构成的形容词
在英语中, 很多名词后加-y可以构成形容词。例如: cloud—cloudy, wind—windy, rain—rainy, sleep—sleepy等。
【学以致用】
①—Is the dish__________ (salt)enough —Yes, it is.
②—What’s the weather like in Shanghai today —It’s__________ (wind).
