Archimedes and the golden crown
One day in ancient Greece, King Hiero asked a crown maker to make him a golden crown. At first, he was very happy (A) ____ it.
"It's a nice crown, isn't it?" he asked his men. Later, however, he began to doubt that it was a real golden crown." "Is it made completely of gold?" he wondered. He sent it to Archimedes and asked him to find out the truth.
"This problem seems difficult to solve. What should I do?" thought Archimedes.
Archimedes was still (B)thinking about this problem as he filled his bath with water. When he got into the bath, (C)一些水溢了出来.
"That's it!" shouted Archimedes. "(D)I know how to deal with the king's problem!"
Archimedes went straight to the palace to see the king. First, he weighed the crown and asked the king for some gold of the same weight.
Next, he put two pots into two big bowls and filled both pots with water. He put the gold into one pot, and some water ran into the bowl. Then he put the crown into (E) ____ other pot. This time, even more water ran into the bowl.
"Look at this," said Archimedes to King Hiero. "A crown made completely of gold displaces less water than a crown made of gold and another metal. This crown displaced more water than gold of the same weight, so I'm (F)certain that it's not completely made of gold."
"The crown maker tricked me, didn't he? What a bad man he is!" shouted King Hiero.
I know how deal with the king's problem!
