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 rocks until 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.

    I've always wanted to try rock climbing, but never had the time or money for it. But I've discovered a way to experience the thrill(兴奋，紧张)of climbing rock, without climbing real rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer！Indoor climbers don't climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms, schools and camps have one.

    You can climb indoors at any time of the year, no matter how the weather is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for the rush(刺激感)they get. When I stand at the foot of the wall and look up. I'm always scared, But once I start climbing, fear changes to determination. With my heart pounding(怦怦地跳), I reach the top and look down. I can't stop grinning(咧嘴笑). I did it!

    Indoor climbing is a great workout. Climbing uses muscles that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

    Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls your climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip. But make sure your partner know how to use this equipment. And if you are a first-time climber, get some instruction before you begin.

    Dear Mike,

    I am so grateful you are coming to see my father at 10:00 a.m. on Sunday. Here is how you can find North Street Hospital.

    After coming to the People's Square, you walk northwards at the traffic lights and then come to the gate of East Street Park. Turn right and walk along the road. You'll find the Police Station. And then turn left and go along the road and take the second crossing on the right. Go on until you reach the end. You'll find North Street Hospital in front of you.

    I'll meet you at the gate of the hospital. I'm sure you'll have no trouble coming here.

Yours,

Wang Ping
