Task 1:是否同意讓graduate students去教一些基礎課程，還是不要教課，只做教授的助手？

參考答案：I think it is a great chance for graduate students to teach some fundamental classes in university.

There are many classes in the department where professors need help in areas such aslecture, discussion. Undergraduates in smaller classes taught by graduate students will have more personal interactions with people actively working in the field.

Also, teaching will build their self-confidence in giving professional presentations at conferences, committee meetings, and qualifying and exit exams. Even if they donot remain an academic for life, many organizations will expect them to give presentations.

閱讀：三個方法減少澳大利亞鯉魚的數量

1. 亞洲通過商業貿易來減少鯉魚的數量

2. 給玉米等鯉魚的食物下毒。不會傷害本土魚

3. 科學家通過基因工程改變鯉魚的基因，讓他們只繁殖male

聽力：反駁

1. 澳洲的鯉魚不好吃，由于蛋白質豐富，只能做動物飼料，但是動物飼料行業已經飽和，所以商業方法不可行

2. 鯉魚能夠檢查到毒素，有毒的飼料不會被吃，而是被留在水里，毒素有可能泄露從而毒害本土魚

3. 基因工程可以改變一些魚，但是水里還有健康的自然魚，它們可以繼續繁殖。洪水把一些寵物鯉魚沖到河里，保證了健康魚的繁殖。

解題思路：聽力內容駁斥了閱讀的三點好處。

參考范文：

While the writer proposes three methods to control the amount of carp in Australia, the lecturer questions the strategies and states the reasons.

The author citesthe example of Asian corps to support the approach related to commerce, but ignores that Australian carp is not as delicious as the Asian one. According to the lecture, carp in Australia being rich in protein can only be produced into feedstuffs. However, there is no space in the relevant market, and therefore this method is unconvincing.

 Another method mentioned in the written article is to poison the food for carp like corns. The professor, on the other hand, objects to it because carp is able to detect toxinsand avoid toxic food. Thus, poison leaked would harm native fish.

The writer also suggests to engineer carp DNA to achieve the population control. The professor argues against the method by mentioning that the GM genes would stop working in the wild population. Besides, floods may bring some carp which is treated as pets into rivers, and the new population ensures the healthy reproduction of the species.
