华南理工大学 攻读博士学位研究生入学考试英语样题Part I. Use of English (l0 points) Directions: Read the following text. Choose the best word for each numbered blank and marked A, B C or D on the ANSWER SHEET. Unlike many ants, trees grow slowly. Thirty to eighty years are necessary before a tree grows to the right size for harvesting as lumber or pulpwood. But a tree crop can be a good investment for a landowner or farmer, since trees will grow on the parts of his land where ordinary crops will not grow. Trees 1 much more than provide lumber for home building. They provide raw materials for making paper, plastics, synthetics, turpentine, and other products. Even more important, trees protect the nation?s water supply by holding 2 erosion and keeping water in the soil. America once had huge natural forests. To start their 3 , pioneers cleared many trees. Later, logging crews 4 by lumber companies moved into other forests. They cut all the valuable trees, and then moved on.. There were few 5 to protect our forests or to plant new ones until the beginning of the present century. Then, 6 with forest experts, government officials, and landowners, the lumber companies began planning to support the planting of new forests. The American Tree Far System, begun during World War II, is one of the plans that grew 7 this cooperation. Landowners who wish to establish tree farms can get help from a professional. state-employed forester, or from an association of lumber companies. They can get 8 on what kind of trees to plant and how to care for them. Landowners must protect their trees by keeping grazing animals 9 and by removing dead or diseased trees. They must keep replanting, so that young trees are growing at all times to replace those 10 for cutting. Some tree farms are small woodlots. Others cover thousands of acres. All together, they are of great value to the United States and its people. 1. A. create B. devote C. have D. do
