Da Vinci, Leonardo
Leonardo da Vinci(1452-1519) was an Italian painter, inventor, musician, engineer and scientist.
Da Vinci was born in the countryside. From an early age, he showed great intelligence and artistic ability. As he grew older, he learnt to do many different things. His paintings are very famous, and one, the Mona Lisa, is perhaps the most f
amous painting in the world. He also had many inventions. For example, his notebooks include some interesting drawings of flying machines. (See Art)
Dinosaurs
Dinosaurs lived on Earth more than 60 million years before human beings. They lived everywhere on Earth. Some dinosaurs were as small as chickens. Others were as big as ten elephants. Some could even fly.
Many dinosaurs ate plants. However, some dinosaurs liked to eat meat.
Dinosaurs lived on Earth for more than 150 million years. Then, suddenly, they all died out. Nobody knows why. However, we can learn about them from their fossils. (See Earth history)

关于狐狸的成语The king and the rice
A long time ago, there was a king in India. The king’s favourite game was chess.
One day, a wi old man came to the palace and the king challenged him to a game. The king promid the old man, “ You can have any prize if you win the game.”
The old man said, “If I win the game, I’d like one grain of rice for the first square of the chessboard, two for the cond, four for the third, and then double the amount for each of the rest of the squares.”
“Is that all?” asked the king. “Wouldn’t you like gold or silver instead?”

“飞云洞No, just rice,” replied the old man.
The king and the old man played the game for a long time. Finally, the old man won. So the king ordered his men to collect a bag of rice. He put one grain on the fi
rst square, two on the cond, and so on. The king quickly realized the problem --- even with all the rice in the country, he would still not have enough rice to put on all the squares!
国王和大米
很久很久以前,有个印度的国王。国王最喜欢的比赛是国际象棋。
有一天,一个睿智的老人来到皇宫,国王向他挑战比赛。国王允诺老人:“如果你赢得比赛你可以拥有任何奖品,。”
老人说:“如果我赢得比赛,我想要一粒大米在棋盘的第一个方格,两粒在第二个,四粒在第三个,然后使每个剩余的方格在数量上加倍。”
“就这些吗?”国王问道。“难道你不想要金银来代替?”
“不,只是大米,老人回答说:。
国王和老人玩了很长时间。最后,老人赢了。国王命令他的助手们收集了一袋大米。他把一
粒放在第一个方格,两粒在第二个,以此类推。国王很快意识到这一问题——即使算上这个国家的所有大米,他仍然没有足够的大米放满所有的方格!
