This is because the crown was not completely made of gold. It had another metal inside, which made it bigger in volume. When two objects have the same weight but different volumes, the one with the bigger volume will displace more water. (1) Why did Archimedes weigh the gold and the crown first? (3分) (2) Why did the crown displace more water than the gold of the same weight? (4分) (3) If you were Archimedes, how would you explain this discovery to the king in English? Write 2-3 sentences. (8分) C2. 跨文化对比思辨写作（中外智者）（15分） Both Archimedes and King Solomon solved difficult problems. Archimedes used science. Solomon used psychology.

(2) Because the crown was not completely made of gold. It had another metal inside, which made it bigger in volume. So it displaced more water. (3) 参考范文：Look, King! 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 know it is definitely not completely made of gold. C2. 跨文化对比思辨写作（15分） 参考范文：I think Archimedes' method is better. He used science to find out the truth. It is objective and convincing. Solomon's psychology is also clever, but it depends on people's feelings. In our daily life, we need both to solve different problems. Science helps us find facts, and psychology helps us understand people.
