成都市武侯区2015阅读理解一轮训练（2）及答案阅读理解Grasslands need time to rest when cattle and other animals feed on them. Moving animals from one area of pasture (牧场) to another can provide the time needed for new growth. This is called rotational grazing .(循环放牧) Rotational grazing is good for the land and the animals, and it can save money. This form of grazing can reduce the need for pesticide (农药) treatments by reducing the growth of weeds. And it can limit the need for chemical fertilizers by letting animal wastes do the job of natural fertilizer. Rotational grazing can even help prevent wildfires by keeping grasslands in good condition.Letting animals feed continually and intensively (集中地) in the same grazing areas can require costly replanting. Animals eat the most desirable growth first. When that keeps happening, the roots do not have enough time to recover. As a result, less desirable plants may replace them. Intensively used grasslands are also harmed as the soil is continually crushed under the weight of heavy animals.While rotational grazing can save money over time, it also requires planning. And that starts with a good map to mark fences, water supplies and grazing areas.Changing methods of grazing also requires time. Farmers may want to put up electric fences to enclose (圈起) grazing areas, called paddocks. The paddocks will need water. Some farmers design a path for animals from different paddocks to drink from a common watering place.Farmers can start rotational grazing by removing animals from a pasture when the grass is eaten to less that five centimeters. The pasture is then kept empty until the grass grows to more than fifteen centimeters high.Sheep and goats may require special preparations. They may need stronger fences than other animals. And while they eat the grass, they may need guard animals to protect them from animals that would like to eat them.67.

阅读下列短文，从每题所给的四个选项（A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑A One day, a slave owner entered a local store and threatened a young boy who was his slave. At first, the slave refused to move and ran for the door. The slave owner reached for a heavy weight. He threw it at his slave. Instead, it hit Harriet on the head. Harriet almost died. For the rest of her life, she carried the mark of a deep wound on her head. Miser Brodas felt he never needed Harriet. He decided to sell her. Harriet thought of a way to prevent this. Each time she was shown to someone who might buy her, she acted as if she were falling asleep. After a while, Mister Brodas gave up the hope of selling Harriet. He sent her back to the fields. At 24 she married a free black man, John Tubman. By then, Harriet was sure she should escape. In 1849, Mister Brodas died. His slaves probably would be sold to further South. John Tubman tried to make Harriet forget about running away. Harriet decided she must end her marriage and that she needed to tell her family that she was leaving. Harriet escaped for Pennsylvania where slavery was banned there. Once she hid under hay that had been cut from the fields. Another time, she wore men’s clothing. Finally, she arrived in Pennsylvania. Now that Harriet was free, she didn’t forget other slaves in Maryland. During the next ten years, she freed her parents and other family members. She traveled back and forth eighteen times, helping about 300 slaves escape. She became an expert at hiding from slave hunters. At one time, anyone finding Harriet was promised 40,000dollars for catching her—dead or alive. The people she helped called her Moses. She had rescued them from slavery just as the biblical Moses rescued the Jews. After the Civil War began, Harriet started to spy for the North. She also served as a nurse. After four years of bloody fighting, the North won the war. Abraham Lincoln freed the slaves in 1863. There was no longer any need for Harriet to be Moses.56. Harriet was hit by a heavy weight on her head when . A. she was helping a slave run away B. she was playing with a young b。
