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黄鹤楼的翻译, is perhaps the most famous 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欢乐颂2插曲)生日情话
Unit 2 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?”
“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 first 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!
