M: The theme of your paper can be about business management or tourism industry in China and the length of your paper should be no less than 15 pages PART B the sound of birds The sound of birds can be divided into three types including singing, crying and voice imitating. Singing is normally a continuous multi-syllable melody uttered by the birds and controlled by sex hormones. Some sorts of singing are quite melodious and pleasant. During the breeding cycle, the changing and pleasant cries of male birds are typical songs. Singing is an important way for a bird to defend its territory, to pronounce it has occupied a place and to warn other birds not to enter the area. The singing variety of birds’ songs are different and more complicated than their common cries, which mainly happen in the breeding cycle in spring and summer. Cries are not controlled by sex hormones and can be uttered by both male and female birds. Usually bird cries are short and simple. But they can mean a lot. They are used to communicate with one another and to warn one another about dangers. The cries of birds can express calling, warning, surprise and threat. Sometimes it is very difficult to distinguish crying from singing. Generally speaking, cries are not affected by the change of seasons and can be made by all birds. Crying is an important way for birds to communicate with one another. Voice imitating birds imitate the crying or voice of other birds. The biological cause of voice imitating is not clear even now and it is highly probable that it will take a long time for people to discover the mystery. Passage II: fun facts about giant pandas High in dense bamboo forests in the misty, rainy mountains of southwestern China lives one of the world's rarest mammals: the giant panda, also called the panda. Only about 1,000 of these black-and-white relatives of bears survive in the wild. Pandas eat almost nothing but bamboo shoots and leaves. Occasionally they eat other plants, fish, or small animals, but bamboo accounts for 99 percent of their diets. Pandas eat fast, they eat a lot, and they spend about 12 hours a day doing it. The reason is very simple. They digest only about a fifth of what they eat. Moreover, bamboo is not very nutritious. The shoots and leaves are the most valuable parts of the plants, so that's what a well-fed panda concentrates on eating. To stay healthy, they have to eat a lot -- up to 15 percent of their body weight within 12 hours -- so they eat fast. There are many species of bamboo. Only a few of these grow at the high altitudes where pandas live today. A panda should have at least two. bamboo species where it lives, or it will starve. Giant pandas used to be able to move quite easily from one mountaintop to another in search of food. Now the valleys are mostly inhabited by people. Pandas are shy; they are afraid to go into areas where people live. This confines pandas to very limited areas. As people continue to farm, cut trees, and develop land higher and higher up the mountain slopes, the pandas' habitat continues to become smaller. And sometimes, when all the bamboo in their area dies off naturally, pandas starve because they're unable to move to new areas where other bamboo species thrive. Conservation organizations and Chinese government officials and scientists are continuing to work toward solving the pandas' isolation problems. Maintaining "bamboo corridors" -- strips of peaceful Rand through which pandas can travel from mountain to mountain freely -- are one of the many ideas that may help save the giant panda. 1.
