Here are two old stories from Chinese history. The Chinese people have told them for many years.
One is a story about Cao Cao's son, a clever boy named Cao Chong. One day, Cao Caogot a huge elephant from Sun Quan and he wanted to know the weight of it. Because there wasn't a scale large enough, some soldiers advised him to(A)it up. But Cao Cao didn't want to kill the elephant. Just then, Cao Chong came up with a great idea. He asked some soldiers to lead the elephant onto about. As the heavy animal walked onto it, the boat went lower into the water. After Cao Chong drew a line on the side of the boat to mark how low it went, the elephant was taken off the boat. (B)The boat was filed with rocksuntil the water reached the line on the boat. Cao Chong then weighed the rocks. The rocks and the elephant were of the same weight. (C)曹操对他的儿子生常满意。
The other story is about a wise man named ZhugeLiang. He was asked to make 100, 000 arrows (箭)within 10days. He told (D) his soldiers to fill 20 large boats with many straw men. In the early morning of the third day, the soldiers said the boats towards the camps of Cao Cao's army on the other side of the river. They shouted and boat their drums loud. When Cao Cao's soldiers heard the sounds, they thought they were (E)attack. However, they could not see through the thick tog on the river. Cao Caoordered his soldiers to shoot arrows towards the sounds of the drums and the shouting. Zhuge Liang got enough arrows and then sailed back successfully.
