Although it was autumn, the snow was already beginning to fall in Tibet. Our legs were so heavy and cold that 1 felt like big pieces of ice. Have you seen snowmen ride bicycles? That's what we looked like! In the late 2 we found it was so cold that our water bottles froze. However, the lakes 3 like glass in the setting of the sun and looked wonderful.

    Wang Wei rode in front of me as usual. She was in high spirits(兴致高) so I knew I didn't need to 4 her. Climbing the mountains was hard work but when we looked around us, we were surprised by the view. We seemed to be cycling through clouds. After a while, we began going 5 the mountains. It was greatly fun as it slowly became much 6. At the foot of the mountains, colourful butterflies flew around us and we saw many sheep eating green grass. Then we had to 7 our caps, gloves and trousers for T-shirts and shorts. In the early evening we stopped to make camp and then we ate. After supper, Wang Wei went to sleep but I stayed awake. At midnight the sky became clearer and the stars grew brighter. It was so 8. There was 9 no wind or sound, only the flames of our fire. 10 I lay below the stars, I thought about how far we had already travelled. We will reach Dali in Yunnan soon!

    We know music is very important in our daily life. Do you notice music playing at any of those places when you go somewhere? Today most stores, stations, restaurants and other places play music. You might even hear music in an office or on a farm.

    Scientists believe that music influences(影响) the way people behave(表现). They think that the sound of western classical(古典) music makes people feel richer. When a restaurant plays classical music, people spend more money on food and drinks. When the restaurant plays modern music, people spend less money. Without music, people spend even less.

    Scientists also believe that loud, fast music makes people eat faster. Some restaurants play fast music during their busy hours. This makes people eat faster and leave quickly. Restaurants can make more money in this way.

    Some scientists think that music makes you think and learn better. They say that music helps students to be more active. It is true that people learn better when they are relaxed. And listening to music can help you relax.

    The next time you hear music somewhere, be careful. It might influence the way you do things.

—Yes, I think so. He isn't a brave boy.

—OK, ______ you want.
