閱讀主要觀點:
一百年前,八哥鳥被引入到北美,它的數量增長得很快。一些人認為八哥鳥是一個有害的物種。
首先,八哥鳥會對農業產生危害。因為它不僅會吃農田裡的植物和種子,還會吃果蔬。
其次,八哥鳥會對飛機產生威脅。八哥喜歡成群結隊地在一起休息、捕食,飛機起飛的跑道是它們選擇休息的場所之一。所以,跑道上成群的八哥鳥會使飛機墜毀。
最後,八哥鳥會與北美的瀕危物種爭搶鳥巢。為了保護瀕危物種,人們為瀕危動物修建了敞開的木質巢箱。然而,八哥會驅趕這些瀕危物種並佔領巢箱。

聽力主要觀點:
八哥鳥對北美並不會造成大的問題。
第一,八哥鳥不僅會吃農作物,還會吃一些對農業有害的昆蟲。所以,有了八哥鳥,可以使農民減少殺蟲劑的使用。這樣就可以減少農民的支出,還可以對環境和人類的健康有好處。
其次,我們可以在機場跑道附近放置很大的籠子,籠子裡放一些八哥鳥來吸引機場附近的八哥鳥到籠子裡來。利用八哥鳥喜歡結伴的本能,便可以捕獲很多八哥鳥,並將它們轉移到安全的地方。
最後,人們可以在人工的巢箱上安裝小的門,這樣體型較大的八哥鳥便無法進入到巢箱,不會對北美的瀕危物種造成威脅。

範文:
The writer makes the point that starlings are harmful invasive species in North America. On the contrary, the professor states that starlings are not a big problem.

First, the professor refutes the viewpoint showed in the passage that starlings would cause agriculture damage by saying that this behavior would bring farmers some benefits too. For example, starlings not only feed on crops but also on insects that damage the crops. If there are starlings around, the farmers do not need to use much pesticide to control the harmful insects. Using less pesticide would save the farmers' money and has some benefits to the environment and human health.

Second, the writer states that starlings' flocking instinct would be dangerous to aircraft. However, the professor points out that the risk can be reduced by taking advantage of starlings' flocking instinct. We can take a large cage to the area and put some starlings in it. This cage is constructed as a trap to attract the outside starlings to join them. As a result, we could capture thousands of starlings near the airport and then move them to other less dangerous location.

Finally, in terms of the competition with endangered species, the listening challenges the point in the reading and demonstrates that there is a way to prevent the starlings from competing with endangered species. We can add small entrances to the artificial nest boxes to stop them from entering the wooden boxes. It is because the starlings are much larger than the native birds in North America.
