1. 蜥蜴，身体的温度是根据环境变化的。还说在沙漠的种类和平常的有什么不同。 2. 动物迁移，提到monarch butterfly, grey whale，还有其他。
grey whale 靠着往南游时，海岸线在它的左手边，往北游海岸线在它的右手边，来记回家的路。monarch butterfly 的部份题目有陷阱，因为帝王蝶冬天时往南迁，在春天结束时先交配，夏天飞到原本北边才产卵，要特别记得是在A 地。mate 在B 地产egg，考题在季节&地点上耍花招。然后有些动物靠不动的北极星认路，有些动物靠地球磁场分辨方向，使得即便在cloudy 的时候也不会迷失方向。
3. 候鸟迁徙。某鸟春天到北方以后下蛋死掉，小鸟自动飞到老鸟冬天去的4kkm 外的地方，有些鸟白天飞靠太阳内置计时器修正太阳方位，有些晚上飞也修正方位，某鸟看北极星不需要修正方位，少数鸟以及大蜜蜂靠磁场阴天也飞。
4. 小行星。同位素监测月亮岩石及流星得知年龄（出题的那个是最大的流星，地球上没观测到过，通过红移监测宇宙年龄）。 词汇题： cases = stop
enormous = very large profound exhibit cluster

1. 找管理员问东西没了，可能在别的storage，答应尽快答复。

2. 牛顿对诗人的影响。以前光对应darkness，现在因为他的论光学，诗人全都写牛顿体可分解光，而且这书用英语而不是拉丁文写的，谁都看得懂，不是科学体。
3. 什么diamond，有黑钻石，地球上只有两处有，不是地球天然的，而是天上掉下来的，黑钻石是粗糙的表面，多孔的。
字神帝国英语学院英文背景知识补充：
Carbonado, commonly known as the \diamond foundin alluvial deposits in the Central African Republic and Brazil. Its natural color is black or dark grey,and it is more porous than other diamonds.
Carbonado diamonds are typically pea-sized or larger porous aggregates of many tiny blackcrystals. The most characteristic carbonados have been found only in the Central African Republic andin Brazil, in neither place associated with kimberlite, the source of typical gem diamonds. Lead isotopeanalyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks.
Mineral grains included within diamonds have been studied extensively for clues to diamond origin.Some typical diamonds contain inclusions of common mantle minerals such as pyrope and forsterite,but such mantle minerals have not been observed in carbonado. In contrast, some carbonados do containinclusions of minerals characteristic of the Earth’s crust: these inclusions do not necessarily establishformation of the diamonds in the crust, however, because these obvious crustal inclusions occur in thepores that are common in carbonados. These inclusions within pores may have been introduced after carbonado formation. Inclusions of other minerals, rare or nearly absent in the Earth’s crust, are found atleast partly incorporated in diamond, not just in pores: among such

other minerals are those withcompositions of Si, SiC, and Fe?Ni. No distinctive high-pressure minerals, including the hexagonal
carbon polymorph, lonsdaleite, have been found as inclusions in carbonados, although such inclusionsmight be expected if carbonados formed by meteorite impact.
Isotope studies have yielded further clues to carbonado genesis. The carbon isotope value is very low(little carbon?13 compared to carbon?12, relative to typical diamonds). Carbonado exhibits strong luminescence (photoluminescence and cathodoluminescence) induced by
nitrogen and by vacancies existing in the crystal lattice. Luminescence halos are present aroundradioactive inclusions, and it is suggested that the radiation damage occurred after formation of thecarbonados, an observation perhaps pertinent to the radiation hypothesis listed below.
4. 同学找老师要推荐信，老师很热情，会帮忙联系那个专案并且系里给加学分。
5. 一个地理形态的形成的。先有个专家说有可能是因为河流，有可能是因为glacial，后来又否定了，另一个专家说是另外一个什么的原因。 6.（缺）
口语
1. 如何提高你的国家的教学品质（education system），用你们国家用的方式解释。 2. 有声读物（listening the audio）和阅读纸本书，你喜欢哪个。 3. 阅读：学校让宿舍生选室友。
听力：女同学不赞成。(1) 和室友一般没什么矛盾，矛盾也是小矛盾；(2) 应该学习化解矛盾走上社会可以用；(3) 住校外的都是为了省钱，就算你可以选舍友仍然会住外面。
Reading: A letter suggests that students should choose their roommates based on two

reasons: fewerconflicts and more dorm residence.
Listening: the woman disagrees with the suggestion: (1). There are not many conflicts betweenroommates; even if there are conflicts, students should learn to overcome them rather than avoid them.Experiencing conflicts and solving them are part of university life. (2). The reason why students chooseto live off-campus is that the price of dorm living is too expensive not that they cannot choose their ownroommates. Therefore, allowing to choose roommates does not solve the problem.
4 阅读：information bias，大概就是人以为资讯越多就越有把握，结果等资讯等的机会没了。 People need information to make decisions, however, sometimes people go too far with this opinion,and thus, they believe more information is always better. This kind of opinion is called information bias.
听力：几年前教授要找个研究助理，第一个人很好，但是他没立即要，而是继续面试一星期人，最后决定要第一个，打电话一问，那个人已经跟别的教授了。
However, when people are addicted to collecting information, the decision might be no longer needed.The professor states an example to illustrate this idea. Several years ago, he tried to find a researchassistant for a project and he interviewed some candidates. The first one was quite impressive with rich
experience, a great knowledge and a degree in related field. The professor liked him. However, insteadoffering the first candidate the job immediately, the professor kept on interviewing others. After oneweek, he could not find anyone else more satisfactory than the first candidate, therefore, he called thefirst person and offered him the job. At that time, the first candidate already accepted another project. As
a result, the professor needed to find someone else who was less qualified for that

5. 一对男女同学的对话，男生靠bike 上下学，但是冬天到了，就无法这样做。他提出两个解决方式。一是他的室友有车，麻烦他室友接他上下学，但这样一来需要依照室友的时间上下学，导致有时候他必须一早没有课，却必须到学校；第二是买便宜的车，他有看到一个 便宜的deal，只是买车、养车会是一笔开销。
问题：summarize the problem discussed in the conversation, which solution do you prefer? The man has a problem: he cannot ride his bicycle in cold weather anymore. They discussed out twosolutions: (1). The man can share his roommate's car, but their class schedules are different; (2). He canbuy a used car from one math student at a reasonable price, but owning a car is actually expensive.
6. Wild life protection. People like go hiking, walking around or viewing scenery in wild nature.However, the action may affect plants and animals. There are two ways to protect the environment fromdisturbing while allowing tourists to visit the nature. (1) People sometimes walk around in forests and create paths. Create a protection to protect delicateenvironments from disturbance.
(2) Restrict number of visitors per day and there are two methods:m1. Group tourists into small groups and assign tour-guide for them; m2. limit the small group numbers.
Two ways to protect natural environment from being damaged by recreational nature walk. (1).Separating humans from the environment by building trails; tourists are only allowed to walk along thetrails; (2). Limiting the size of the visiting group. Only small groups under with guides are allowed, and
thus reduce the impact on the environment.
