　　參考范文Both reading and listening talks about how global warming has been deteriorating. According to the reading, there are three problems with the rocket that releasing sulfur dioxcide into the air, yet the professor in the listening casts doubt on the statement in the reading.

　　First, the reading points out the fact that it may produce acid rain, which affects the environment negatively. Yet the listening part explains that in fact acid rain is not that easy to produce; instead it only rains under specific condition. Specifically, there won't be acid rains when vapor is little. In this case, it's almost impossible to produce acid rain every time.

　　Second, the passage presents that the rocket costs a lot, which is not worthy at all. However, the listening makes it clear that indeed other ways are available, yet they are more expensive. So the price is quite fair to launch the rocket.

　　At last, the effect brought from rockets is little. But the professor mentions that it is effective actually. Even though the temperature hasn’t changed too much, it can alleviate glaciers melting. ［181］
