　　参考范文

　　Both the reading and the listening discuss about the invasion of Asian carp into the rivers leading to the Great Lakes. The reading raises three possible ways to deal with it, while the listening contends that they are not feasible .

　　First, as the reading suggests, the walls can be built to prevent the fish from coming into the Great Lakes. However, the listening points out that the walls will affect shipping on the rivers because the goods from surrounding factories should be unloaded before being reloaded onto another ship. Moreover, with the industries along the rivers harmed, the shifting construction will increase related expense.

　　Second, the reading mentions that the electrical charged device can be used to eliminate Asian carp. The listening, on the other hand, argues that the reach of the rivers is really wide, so some fish can escape from electrocution. Besides, still some others can pass through the device for reproduction.

　　Third, the author further illustrates that the use of certain toxic chemicals, together with the reintroduction of native species to the rivers, can be advocated. However, the lecturer holds that this method is tried in small bodies of water, which is hazardous and hard to predict possible results. What is worse, the whole ecosystem would be negatively impacted, which is harmful to the growth of fish species.
