　　Conversation 1

　　M: Hey, I just read a great book about physics. I think you’d like it. It’s called the Physics of the World. It’s written by a scientist named Sylvia Mendez.

　　W: Oh I read that book. (1)It was great. The writer is a warm and competent guide to the mysteries of physics. I think it promises enrichment for any reader from those who know little about science to the career physicist.

　　M:(2)And it’s refreshing to see a strong curious clever woman adding her voice to the scientific discourse and a field that has been traditionally dominated by men. I think she has to be commended for making an effort to include anecdotes about little known female scientists. You know they were often victims of a generation firmly convinced that the woman’s place was in the home.

　　W: (3)I like how the book is clearly written with each chapter brought to life by pieces of fascinating knowledge. For example in one chapter she exposes a myth that I’ve heard taught by university physics professors. I’ve often heard that medieval glass windows are thicker at the bottom because glass flows like a fluid. This, she shows, is not true. The distortion is actually thanks to a peculiarity of the glassmakers’ process.

　　M: (4)Yeah I like how she cultivates scientific engagement by providing a host of Do It Yourself experiments that bring the same foundational principles of classical physics that govern everything from the solar system to your kitchen table.From using complex laws of physics to test whether a spinning egg is cooked to measuring atmospheric pressure by lifting a piece of cardboard. Her hands-on examples make her book a truly interactive read.

　　W: Yes I must say this a equation-free book is an ideal read for scientists of all stripes, anyone teaching science and even people who dislike physics.

　　Question 1: What does the woman say about the book the man recommended?

　　Question 2: What can we find in the book the man recommended?

　　Question 3: How does the author bring her book to life?

　　Question 4: How does the book cultivate readers’ interest in physics?

　　我们首先来看考场里面的一组对话，第一部分还可以，后边发生了一系列转变。男士说，“Hey, I just read a great book about physics.”，我读了一本关于物理的非常好的书……男人引出话题。

　　女士说，“Oh I read that book. It was great. The writer is a warm and competent guide to the mysteries of physics. I think it promises enrichment for any reader from those who know little about science to the career physicist.”，我也读过那本书，书写的特别好。作者非常热情，而且能把我们指引向物理学的神奇所在。我觉得这本书丰富了那些对物理学知之甚少的读者甚至物理学家的认知。女士在讲这本书的好处和目的。

　　第二组对白当中，男的说“And it’s refreshing to see a strong curious clever woman adding her voice to the scientific discourse and a field that has been traditionally dominated by men.”，有意思的事情是女性以前一直处于由男性统治的领域中，第二道题，知道这个关键信息就可以了。再往下，女的待的地方是in the home，女性是受害者。第二个内容，男性所表达的话语，这样一本书打破了人们以前的观点，女的可以在自然科学领域当中做出自己的建树。

　　紧接着女士说自己喜欢这本书，它非常清楚的写出每一章，通过引人入胜的每一个知识点。后边她给了一个小的例子。男士说从大到太阳系，一直小到家里的厨房，都是同样的物理法则。

　　During the arctic winter from October to March, (9-1)the average temperature in the frozen north typically hovers around minus 20 degrees Celsius. But this year the Arctic is experiencing much higher temperatures. On February the 20th the temperature in Greenland climbed above freezing or zero degrees Celsius and it stayed there for over 24 hours. Then on February the 24th the temperature on Greenland’s northern tip reached six degrees Celsius. (9-2)Climate scientists describe the phenomenon as stunning. (10)Weather conditions that drive this bizarre temperature surge have visited the Arctic before. They typically appear about once in a decade. However, the last such increase in temperature took place two years ago.This is troubling as climbing arctic temperatures combined with rapid sea ice loss are creating a new type of climate feedback loop which could accelerate Arctic warming. Indeed, sea ice cover in the Arctic is melting faster than expected. Without those masses of cooling sea ice, warm air brought to the Arctic can penetrate further inland than it ever did before. The air can stay warmer longer too. This drives additional melting. Overall earth is warming at a rapid pace. 2014 through 2017 rank as the hottest years on record and the Arctic is warming twice as fast as any place else on earth. This raises unique challenges for Arctic wildlife and indigenous people who depend on Arctic ecosystems to survive. Previously climate forecasts predicted that Arctic summer ice would disappear entirely by around 2060, (11)but based on what scientists are seeing now, the Arctic may be facing summers without ice within 20 years.

　　Question 9: What did climate scientists describe as stunning?

　　Question 10: What does the passage say about that temperature surge in the Arctic?

　　Question 11: What may occur in 20 years according to scientists’ recent observations?

　　接下来这个篇章讲的是北冰洋融化。hover表示“盘旋”。在北极的冬天，平均气温大概盘旋在多少度呢?“minus 20 degrees Celsius”，零下20度。“But”做强转折，这个地方就形成了开篇考点，第一道题答案显而易见。2月20号，格林兰岛北端达到了6度。气候学家把这种现象描绘为“stunning”，这个词表示令人震惊，令人吃惊的，科学家把它描绘成一个令人震惊、令人吃惊的事情。开篇两个地方说了一个问题，就是气候上升。这种气温剧变以前在极地也出现过的，大概是十年出现一回。“However”，强转折，强转折处要出答案。然而上一次气温剧变是在两年前。

　　再往下，随着气温上升以及冰的消失，实际上创造出了一种新的气候反馈回路，它能够加速极地变暖。确实，现在极地的冰层融化的速度比预期的要快。没有了低温海冰，暖空气比以前更加容易渗入内陆，它又进一步带来了融化。全球变暖以非常高的速度在进行。2014年到2017年，“hottest”这个是一个最高级，它可以命题，也可能不命题，2014年到2017年是温度最高的几年。极地融化速度是其他地方的2倍。这对当地人和动物带来了问题，他们是依据极地的气候生存的。之前我们预测北极海冰会在2060年完全消失，But强转折，然而，基于现在科学家们所观察到的东西，20年之内就看不见海冰了，转折处是考点。

　　综上，如果在考场当中能够把握住开篇段首句和but，就能找到答案。

　　最后，希望大家把英文当成一个生存的本事，背单词加入发音，纠正发音。学英文的时候，搞清楚单词与单词之间高语速的关联。同学们找工作的时候会发现真正的听和说的能力，有时来的比阅读写作的能力更加重要。希望通过英语学习，大家得到的不仅是六级证书，而是更加广阔的另外一片天地。
