【题目】Whether the declining of bison was caused by the European American settlers.
阅读要点
【阅读】About bison, a kind of animal, something like cattle or horse. The passage suggests that the declining bison was due to the European American settlers:
1. When European American cross prairies, they hunted bison as food because there is no food in prairies.
2. They brought cattle and horses, which competed with bison for resources.
3. The evolving technology, especially guns, let hunters kill several bison in a short time.
听力要点
【听力】The professor contradicts each of these three points:
1. The European American moved from east to west, but the bison decline in the western part of America. The pattern of how bison disappeared gradually was different from that of movement of European American.
2. Bison have double furs covering their bodies and unique head structure, which allow them to live in harsher and colder areas. The areas were unreachable for cattle and horses. How could different spices compete with each other in separate territories?
3. The advanced technology should not be blame worthy for the decreasing bison. The ancient methods are as effectively as guts. Skilled ancient American hunters could kill several bison with short intervals.

话题
【题目】Arizona发现一个2亿年前的虫子的巢化石是不是蜂巢。
阅读要点
【阅读】 很多人认为这是蜂巢，但这是不可信的。
1. 2亿年前还没有蜜蜂，哪里来的蜂巢；
2. 2亿年前连flowering plants都没有，怎么会有需要吃花蜜的蜜蜂；
3. 现代蜜蜂的巢都有个盖子cap，那个化石没有，所以这个巢很可能是其他虫子的。
听力要点
【听力】 反对，这个化石是蜂巢。
1. 没有发现有200百万年前的蜜蜂化石不代表没有200百万年前的蜜蜂，那时候蜜蜂筑巢的树比较难留下来，所以没有化石也正常。
2. 古时候的蜜蜂就一定要吃花蜜吗？他们不能吃nonflowering plants吗？
3. 没有盖子cap可能因为化学原因， 腐蚀掉了什么的，再说为什么要跟modern bee一样呢？

话题
【题目】雨蛙抵御某种真菌的三个方法是否可行。
阅读要点
【阅读】
1. 雨蛙群居可以抵御真菌感染。
2. 一种化学物质可以使雨蛙对病毒免疫。
3. 雨蛙的自身防御，一旦觉得感染了就使自己体温升高来抵御感染。
听力要点
【听力】全部否决
1. 那个湖中不仅有雨蛙还有其他生物，他们可以携带病毒来感染雨蛙。
2. 那个化学物质留存时间很短，在雨蛙遇到病毒之前这种物质就已经失效了。
3. 雨蛙上升自己体温来防御会消耗大量体力，就会使雨蛙特别的虚弱，抵抗力就会下降，进而就很容易死亡。

阅读要点
【阅读】在美国，某些人认为电子病历有三个优点。
1. 省钱，不会发生错误，和利于做科研。
2. 电子病例是用电脑写的，因此辨识度很高，不容易错。
3. 电子病历利于更方便的取得大量病人的相关资料做研究。
听力要点
【听力】
1. 教授认为这些优点是不确定的，他说，即使有了电子病历，医生们还是会把纸质病历作为备份，所以存储转移这些病历的费用并没有省下来。
2. 虽然电子病历使用电脑，但是还是难免出现错误，因为病历还是由医生手写，职员打字输入的，在辨识医生的文字和输入电脑的过程中都有可能出现错误。
3. 教授说在美国病人的病历属于隐私的范畴，有隐私法来监督，研究人员不可能随意的查看病人的病历，首先他必须经过严格复杂的程序获得很多人包括病人自己的允许才能查看病历，所以关于电子病历的这个优点是不存在的。

话题
【题目】关于saber-toothed cat(剑齿猫)是否是群居动物。
阅读要点
【阅读】saber-toothed cat是群居动物。
1. Fossils of saber-toothed cats with broken bones indicate that they were fed by other saber-toothed cats when they were injured
2. There are large numbers of saber-toothed cats in the trap. The saber-toothed cats hunted together. The sound of dears in the trap attracted them to fall in the trap together
3. Saber-toothed cats lived with other predators such as lions and wolves. Saber-toothed cats have to live in group to compete with those predators.
听力要点
【听力】剑齿猫不是群居动物。
1. The fossils of saber-toothed cats with broken bones indeed indicate that they could survive when they were injured. However it doesn’t necessarily mean that they have to be fed by other saber-toothed cats. Many predators can find dead animals to eat. So did the saber-toothed cats
2. The large numbers of saber-toothed cats in the trap doesn’t mean that they hunt together. The saber-toothed cats hunt separately. One of the saber-toothed cats heard the sound of the trapped dear, went to the trap and fell. Then another saber-toothed cat also heard the sound of the trapped dear, came to the trap and fell again
3. Saber-toothed cats were large predators. Take tigers for example, one tiger is strong enough to fight against the social predators such as lions and wolves. So the saber-toothed cats don’t have to live together to compete with lions and wolves.
