Question

At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage buildings or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice．

    Here is a way to kill mice without spending a lot of money. It is a simple but effective kind of mouse trap. The method is first used by some farmers in the west African country of Mali. An agricultural expert in Mali reported about the Mali mouse trap in a magazine. The expert reported that his gardener caught 150 mice in just one night. The gardener used four traps. The trap is easy to make. First, remove the top from a 20 liter metal or plastic container(容器). Put it in a hole in the ground. The top edge of the container should be the level with the surface of the ground. Fill the container with water to within eight centimeters of the top. Add tiny pieces of grain wastes. They should float on the water. Also put some wastes on the ground near the trap. During the night, mice will come out to eat the grain wastes. They will fall into the container and drown. Replace the food in the trap every night．

【解析】

试题分析：本文介绍了人们最早使用的最简单但是最有效的捕鼠的方法，最早使用这个方法的是西非的马里，它是用盛20升的金属的或塑料的容器，去掉它的顶部，在地上挖一个洞，把容器放进去，容器不能高于地面，然后倒入水，水的高度离容器的顶部8公分，然后在水里和容器周围的地上撒上一些谷物，等到老鼠来吃的时候，就会掉进水里淹死了。

1.细节理解题。根据The method is first used by some farmers in the west African country of Mali. 用陷阱方法来逮老鼠最早是西非国家马里使用的，故选D。

2.主旨大意题。根据It is a simple but effective kind of mouse trap.这段主要介绍了一个简单而有效的捕鼠的方法，故选A。

3.细节理解题。根据Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice．及It is a simple but effective kind of mouse trap.没有提到地上的洞能捕鼠，故选D。

4.细节理解题。根据The top edge of the container should be the level with the surface of the ground. 容器的最顶部应该与地面持平，故排除CD; Fill the container with water to within eight centimeters of the top.向容器装的水离容器的顶部8公分，所以排除A，故选B。
