TASK 3 Integrated Reading/Listening/Speaking
材料要点重现：男生不同意取消晚课这个决定。原因有两个，一个是晚课虽然规模很小，但就是由于这个小规模，同学们才能参与的更多，从而更好的学习。第二个是尽管晚课的老师可能并非经验丰富，但恰恰是由于他们没有那么多的教学经验，才会使他们对课程充满热情。
高分词汇：scale, participate, enthusiasm, in contrast, dedicate
范文：The school has implemented a new policy that the university will stop offering evening classes in many departments starting next fall due to the small scale of them and the unexperienced teaching staff. And the man holds a negative view towards the announcement. The first reason he gives is that thanks to the small classes, students can participate more and be more actively involved, get more attention and learn more. And the second one is based on the fact that some experienced teachers are lack of enthusiasm because they may have been teaching the same subject for too long. In contrast, if this is their first or second time teaching a class, it’s going to be so exciting to them and they’ll definitely dedicate more. Therefore, he disagrees with that opinion.
TASK 4 Integrated Reading/Listening/Speaking
材料要点重现：教授举了一个土拨鼠的例子。当人类经过土拨鼠时，它们就会像狗一样叫，并且上蹿下跳，以此来警告周围的同伴。但是当人们每天不停的经过它们时，它们就不会再有如此反应了。
高分词汇：frequently, instinctively, prey on
范文：In the lecture, the professor mainly talked about the theory that through habituation a natural behavior gradually changes. To reinforce the theory, the professor gave an example in his speech. That is, assume prairie dogs live in an area where human beings frequently come and go. The first time the animals see a person, they’d react by barking like a dog and jumping up and down instinctively to warn or alert other prairie dogs nearby, they’d do the same to the animal that preys on them, such as a snake or a hawk. This kind of reaction is out of their fear. And they’d keep an eye on the human beings until these possible threatening individuals are gone. However, if people pass through the area day by day without hurting them, then the prairie dogs will gradually stop barking and jumping up and down when they see a person passing through the area, they’d stop reacting to humans as a threat. And that's the example the speaker presented to explain his idea.
TASK 5 Integrated Listening/Speaking
材料要点重现：女生的问题是写历史作业中需要用到的文档现在暂时无法使用。男生提出了两个建议，第一个是换一个课题重新写，但是女生已经收集了很多这个课题的资料。第二个是等到文档可以使用时再接着写。
高分词汇：postpone, right away
范文：In this conversation, the woman is having a hard time dealing with the problem that the documents she needs to use in her history assignment isn’t available right now, so she can’t work on her paper. And the man offers her two possible solutions. One is to change what she is writing about, that is to choose a topic that doesn’t involve those documents. But the woman has already collected a lot of information and if she changed her topic of the paper, she couldn’t use any of them. The other is postpone working on the paper and wait until the documents available again. And if it were my choice, I would choose the former one, because in this way, she can work on the paper right away. Since the documents have to be available in two weeks, which means she has to do a lot of other things in the last week of the school term, and it’ll leave her no time to finish the paper.
TASK 6 Integrated Listening/Speaking
材料要点重现：教授举了雷鸟的例子来说明气候变化会导致一些动植物的灭绝。研究者在同一个地方找到了雷鸟大量的尸骨，于是推测可能发生了气候变化。他们认为如果很长一段时间比较干燥没有雨水，那么雷鸟就会聚集在一个有水的地方，等最后一点水分也蒸发掉了的时候，它们就会一起死掉，从此灭绝。
高分词汇：occur, lead to, extinction, flock, dry up
范文：In the lecture, the professor provides an examples to illustrate the theory that when a major climate change occurs, it may lead to the extinction of various animals and plant species. That is, a giant Australian bird called thunderbird became extinct due to a climate change. Researchers have found many thunderbird bones all together in one spot which is really rare. So they believe that there is a climate change behind it. The hypothesis is, they think that during a long and dry period, the birds may have flocked together at this lake. And if it lasts too long without raining, the birds have to gather there and die. Scientists think the lake where they found the bones was one of the last remaining sources of freshwater during the drought. So the birds gathered there and struggled for a while and eventually the lake dried up and the species was extinct. And that's the example the speaker presented to explain the theory.
