Reading: lionfish 从Indo 洋扩展到太平洋了，阅读中有三种方法来解决： 1. 人工捕捉它们来protect coral reef 生物系统; 2. 引入fish market，这样可以减少对 local fish 的需要，让他们能有时间 recover; 3. 人们可以把它们用于日常饮食，因为它们高蛋白，低脂肪。 Listening: 教授全部反对： 1. 人工捕捉无法区分lionfish 和其他鱼，很多 rare 的鱼也都在coral reef ，会牵连其他鱼种； 2. 引进市场会导致有人人工养殖。 Lionfish 如果从 fish farm escape ，这就造成了更严重的 invasive 问题； 3. 有些lionfish 是有毒的，吃了以后会造成 vomiting numbness arching，我们无法检验每一条鱼，所以不吃他们。
The listening and the reading both discuss three ways of tackling lionfish’s expansion from the Indian Ocean to the Pacific. However, what the reading suggests is quite different from the main idea in the listening. First, in the reading, it is said that the migrated lionfish should be captured by human to protect the coral reef system. In contrast, the professor holds a different view that many people cannot distinguish lionfish from other fishes. Moreover, many rare fishes also live in coral reef, which means that the way mentioned in the reading will do harm to other kinds of fishes. Second, the author of the reading asserts that local fish can have enough time to recover if we introduce the lionfish to the fish market. On the contrary, the lecturer refutes such opinion by pointing out that domesticating lionfish fails to promise the safety. That is, if the lionfish escapes from farms, more invasive problems need to be fixed. This directly contradicts what the reading indicates. Third, the reading passage considers that eating the lionfish for its protein and little fat can also solve the problem. Nevertheless, the speaker disagrees with this perspective and says that some lionfish is toxic and if we take it as food, we will suffer from vomiting numbness arching. What’s more, it is impossible for us to examine every fish, so it is unreasonable to east the lionfish. This is another part where the listening contravenes the reading. (243 words)
