2018年12月四六級真題答案※ 微信對答案 ※ 萬題庫估分

　　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?

　　我們首先來看考場里面的一組對話，第一部分還可以，后邊發(fā)生了一系列轉(zhuǎn)變。男士說，“Hey, I just read a great book about physics.”，我讀了一本關(guān)于物理的非常好的書……男人引出話題。

　　女士說，“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.”，我也讀過那本書，書寫的特別好。作者非常熱情，而且能把我們指引向物理學(xué)的神奇所在。我覺得這本書豐富了那些對物理學(xué)知之甚少的讀者甚至物理學(xué)家的認(rèn)知。女士在講這本書的好處和目的。

　　第二組對白當(dāng)中，男的說“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處于由男性統(tǒng)治的領(lǐng)域中，第二道題，知道這個(gè)關(guān)鍵信息就可以了。再往下，女的待的地方是in the home，女性是受害者。第二個(gè)內(nèi)容，男性所表達(dá)的話語，這樣一本書打破了人們以前的觀點(diǎn)，女的可以在自然科學(xué)領(lǐng)域當(dāng)中做出自己的建樹。

　　緊接著女士說自己喜歡這本書，它非常清楚的寫出每一章，通過引人入勝的每一個(gè)知識點(diǎn)。后邊她給了一個(gè)小的例子。男士說從大到太陽系，一直小到家里的廚房，都是同樣的物理法則。

　　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?

　　接下來這個(gè)篇章講的是北冰洋融化。hover表示“盤旋”。在北極的冬天，平均氣溫大概盤旋在多少度呢?“minus 20 degrees Celsius”，零下20度�！癇ut”做強(qiáng)轉(zhuǎn)折，這個(gè)地方就形成了開篇考點(diǎn)，第一道題答案顯而易見。2月20號，格林蘭島北端達(dá)到了6度。氣候?qū)W家把這種現(xiàn)象描繪為“stunning”，這個(gè)詞表示令人震驚，令人吃驚的，科學(xué)家把它描繪成一個(gè)令人震驚、令人吃驚的事情。開篇兩個(gè)地方說了一個(gè)問題，就是氣候上升。這種氣溫劇變以前在極地也出現(xiàn)過的，大概是十年出現(xiàn)一回�！癏owever”，強(qiáng)轉(zhuǎn)折，強(qiáng)轉(zhuǎn)折處要出答案。然而上一次氣溫劇變是在兩年前。

　　再往下，隨著氣溫上升以及冰的消失，實(shí)際上創(chuàng)造出了一種新的氣候反饋回路，它能夠加速極地變暖。確實(shí)，現(xiàn)在極地的冰層融化的速度比預(yù)期的要快。沒有了低溫海冰，暖空氣比以前更加容易滲入內(nèi)陸，它又進(jìn)一步帶來了融化。全球變暖以非常高的速度在進(jìn)行。2014年到2017年，“hottest”這個(gè)是一個(gè)最高級，它可以命題，也可能不命題，2014年到2017年是溫度最高的幾年。極地融化速度是其他地方的2倍。這對當(dāng)?shù)厝撕蛣游飵�來了問題，他們是依據(jù)極地的氣候生存的。之前我們預(yù)測北極海冰會在2060年完全消失，But強(qiáng)轉(zhuǎn)折，然而，基于現(xiàn)在科學(xué)家們所觀察到的東西，20年之內(nèi)就看不見海冰了，轉(zhuǎn)折處是考點(diǎn)。

　　綜上，如果在考場當(dāng)中能夠把握住開篇段首句和but，就能找到答案。

　　最后，希望大家把英文當(dāng)成一個(gè)生存的本事，背單詞加入發(fā)音，糾正發(fā)音。學(xué)英文的時(shí)候，搞清楚單詞與單詞之間高語速的關(guān)聯(lián)。同學(xué)們找工作的時(shí)候會發(fā)現(xiàn)真正的聽和說的能力，有時(shí)來的比閱讀寫作的能力更加重要。希望通過英語學(xué)習(xí)，大家得到的不僅是六級證書，而是更加廣闊的另外一片天地。
