When the crown came back, it weighed exactly the same as the gold. But the king was not sure. Had the goldsmith kept some gold and added silver? / He called Archimedes, the most gifted scientist in the city. “Find out the truth,” he said, “or I will not believe you again.” / Archimedes thought for days. He could not cut the crown open, because that would destroy it. Then, one morning, he stepped into a bath and saw the water rise. Suddenly he understood: an object pushes away its own volume of water. Gold and silver have different volumes for the same weight, so the crown would displace a different amount of water. / He ran out of the bath and into the street, shouting “Eureka! Eureka!” / The test was simple. The crown was not pure gold. / The principle he discovered is still taught in every physics class. And Archimedes is remembered not only for the answer, but for the way he asked the question. 任务一：单项选择 1.Why did the king call Archimedes? A.To find out if the crown was pure gold. B.To make a new crown. C.To build a bath. D.To teach his children. 2.Why couldn't Archimedes cut the crown open? A.Because that would destroy it. B.Because it was too hard. C.Because the king said no. D.Because he had no tools. 任务二：判断正误(T/F) 3.Gold and silver have different volumes for the same weight. (　　) 4.The crown turned out to be pure gold.

He was a writer, an astronomer and an inventor, and he served the Han government for many years. / Earthquakes were a great danger at that time. News of a quake travelled slowly, and the government could not send help quickly. Zhang Heng decided to build a machine that could tell the direction of a distant quake. / In 132 CE, he finished his seismoscope. It was a bronze vessel, about two metres across, with eight dragons around it, each holding a bronze ball. Below each dragon sat a toad with its mouth open. Inside, a pendulum moved when the ground shook. If a quake came from the west, the west dragon opened its mouth, and the ball fell into the toad's mouth with a loud ring. / At first, officials did not believe the machine. Then one day a ball fell, but nobody in the capital felt anything. A few days later, a messenger arrived: a serious earthquake had hit the west. / The instrument could not predict quakes, but it could report them. For the first time, people had a tool that listened to the earth. 任务一：单项选择 1.What happened when a quake came from the west? A.The west dragon dropped its ball. B.All eight dragons moved. C.The vessel broke. D.The toads rang a bell. 2.What could the instrument do? A.Report the direction of a quake. B.Predict the exact day of a quake. C.Stop a quake.

I tried to come up with a simple way to solve the problem without buying an air conditioner. My idea was a “window clock”: a small card on the window that reminds the class to open it at two o'clock and close it at four. I also brought two old fans from home and put them near the back wall. The room became much cooler, and our teacher stopped opening the door every ten minutes. It is not a great invention, but it solved a real problem with almost no money. 学科网（北京）股份有限公司 $
