Topic 水星上为什么会出现的黄光？

说的是Venus，金星 Yellowish Golden Light, 又称""Ashed Light""

阅读：

水星上出现的黄光有三个原因 proposes 3 causes

1、由于太阳的紫外线照射，氧原子变成氧分子，这个过程生成黄光。

2、闪电是原因。 闪电只是分原因，主原因缺失。

3、由于地方天气不同看见的幻象。两个原因：由于望远镜的问题或者地方天气不同看见的。

听力中一一驳斥：

听力：

1、这个过程生产的是绿光，不是黄的。

2、闪电常常在发生在白天，晚上很少发生，但黄光是在晚上发生的。这个我记得挺清楚的，和2楼一样，说的是Day side和 Night side，然后说the light in Night side is too weak to be observed。

3、观察是不同的人，地方和机器在相同的时间都看见了，不是幻想。不是“幻想”，而是problem和occasionally的产生。

阅读：材料說了防止Asian carp进入Great Lakes 的三种方案
1阅读说construct walls in Great Lakes
听力说这个shipping有影响，cargo 要从一个船reload到另一个船上，增加了cost.
2.阅读说利用electrical charged device to eliminate Asian carp.
听力说这样无法覆盖全面，carp可以游到other side 从而进入到lake
3.阅读说two-step measure. First, 通过toxic chemicals 把所有的鱼毒死。Second, 再引进native species.
教授说这种做法试过，unpredictable. Dangerous. 而且利用toxic chemical 之后可能会导致whole ecosystem发生变化，不利于鱼类生长

NO.4

article讲述养鱼场的三个弊端：

2）. 一些饲养的鱼逃跑跟野生鱼交配产生存活能力低的后代

3）. 渔场浪费淡水资源

professor根据三点提出三个solution：

1）. 可以样一种marine animal吃鱼的排泄物。。。-_- "" 传说中的吃屎

2）. 通过genetic modify让人工饲养的鱼失去生殖能力。。。-_- "" 传说中的阉鱼

NO.5

综合写作是GM plant。阅读段子里说它好，因为

1）可以导入抗虫基因，少用杀虫剂，有利于保护环境

2）可以耐干旱，在非洲种的话可以提高农民收入

3）可以让大米里含更多维生素A，防止维A缺乏。听力部分认为GM的好处被夸大了，因为

1）这种基因如果扩散到野草里，那野草也该疯长了，一样破坏生态平衡

2）农民往往用去年的种子播种，用GM种子的话就得年年买新种子，多花的钱也许比多赚的还多

3）含维生素A的蔬菜有的是，含量还比这种GM大米高，为什么不建议人们吃蔬菜就得了。
