The Northern Pike is a very bad fish. It is a big, hungry fish, and swallows little fish such as trout and perch. Many Northern Pikes live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike are a serious threat to the lake because they eat all the smaller fish. Soon, all other species of fish in the lake will be killed off. This is not healthy for the environment.
Experts are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.
For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They haw. tried using nets, explosives and poisons. However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poi- sons are bad for humans who use the water. No trace of the poisons has ever been found in local wells, however.
Scientists are going to try the poison again. This time, they will drain the lake before they add the poison to the water. A public hearing will be held to talk about the problem.
What are the experts afraid will happen?
选项
A、The Northern Pike will die.
B、The wells will be polluted.
C、Poisons will kill the Northern Pike.
D、The Northern Pike will swim into other lakes.
答案
D
解析
第二段。戴维斯湖有许多小河流人,它与许多小湖相通。专家就担心北梭子鱼会借其道流入其他的湖,继而到处泛滥。选项D是正确的。选项B是当地百姓所担心的。
