總論點：新幾內亞扁形蟲flatworm通過植物上的泥土傳播到歐洲，並對歐洲的動物造成巨大威脅。有三個方法可以控制它在歐洲的擴張。

分論點一：生物控制。一是可以在新幾內亞找到這種扁形蟲的捕食者來吃它；二是讓歐洲本土的鳥或爬行動物吃它。

分論點二：化學控制。用一種不傷害其他動物的殺蟲劑來消滅flatworm

分論點三：土壤消毒。扁形蟲生存在盆栽植物中，並且它不耐高溫。所以只要將所有進口的盆栽植物在50攝氏度的水裡。

聽力主要觀點提取

總論點：閱讀中提到的每一種方法是無效的。

原因一：一方面，這種扁形蟲在新幾內亞並沒有任何捕食者。另一方面，歐洲本土的鳥類和爬行動物也不會吃它，因為它的肉是酸的，並不好吃。

原因二：大部分殺蟲劑都不能消滅新幾內亞扁形蟲。只有一種名為lindane的殺蟲劑可以消滅它，但是同時還會消滅其他動物，所以使用這種殺蟲劑得不償失。

原因三：土壤消毒不能消滅歐洲所有扁形蟲。盆栽植物中有很多泥土，即使將盆栽植物傾倒出來，還有一部分依附在植物深處泥土中的扁形蟲並不會被高溫殺死。

【範文】

The writer puts forward three methods to control the further spread of New Guinea flatworm. However, the professor demonstrates that none of the methods turns out to be successful.

First, as for the biological control, the professor contradicts the reading material. On the one hand, the New Guinea flatworm has no predator in its habitat. On the other hand, the local predators in Europe, like birds or reptiles, would not eat the flatworm because its meat tastes sour and unpleasant.

Second, the professor illustrates that the chemical control mentioned in the reading is ineffective. It is because that the New Guinea flatworm is resistant to most of pesticides. What’ more, the flatworm would be killed by one type of pesticide, lindane, which is very toxic for other species. So it is not worth to use lindane to kill flatworm.

Third, the writer points out that the spread of the flatworm could be prevented by properly sterilizing the soil pots. In contrast, the professor refutes the idea by saying that hot water may not destroy all flatworms. The reason is that flatworms’ older eggs are buried deep within the soil and tipping the pots will not allow the heat to kill the eggs in the deep soil. So they will escape the tip and survive.
