The Northern Pike is a very bad fish. It is a big, hungry fish, and eats little fish. Many Northern Pike live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike area serious danger to the lake because they eat all the smaller fish. Soon, all other kinds of fish in the lake will be killed off. This is not healthy for the environment (环境).
Researchers 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 have tried using nets and poisons (毒). 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 poisons are bad for humans who use the water. However, people haven’t found any poisons at all in local (当地的) wells.
Scientists are going to try the poison again. This time, they will dry off the lake before putting the poison in. A public hearing will be held to talk about the problem.
What was the result of using poisons in Lake Davis?
选项
A、People stopped using the well water.
B、The lake was seriously damaged.
C、The poisons worked as expected.
D、There were hardly any effects.
答案
D
解析
