The global averagesurface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6°F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.Earth’s natural greenhouse effect Earth’s temperature begins with the Sun. Roughly 30 percent ofincoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbedsolar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbedby water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorbthe energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in alldirections. The energy that radiates back toward Earth heats both the lower atmosphere and the surface,enhancing the heating they get from direct sunlight. This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouseeffect, the Earth’saverage surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.What has scientists concerned now is that over the past 250 years, humans have been artificiallyraising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly byburning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolutionbegan in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methanelevels have increased 148 percent.II.拓展提高书面表达如何解决全球变暖是我们全人类共同面临的一个难题。

The name, one of the five proposed for the little panda, received 44 percent of the estimated 200,000 votes cast on the zoo鈥檚website. The little panda went without a name for his first hundred days in observance of a Chinese custom. It鈥檚rare for pandas, born in captivity, to live more than a few days, and keeping the animals nameless is seen as a way to trick fate into letting them survive. The cub wasn鈥檛present at his naming ceremony. The zoo officials said he probably wouldn鈥檛be making his public debut until some time in December. Panda fans celebrated Tai Shan鈥檚day at a zoo ceremony featuring performances by Chinese dance troops and martial artists. Tai Shan usually spends the morning with his mother, Mei Xiang. His handlers are slowly introducing him to the exhibit where he鈥檚expected to go on public view within the next couple of months. Mei Xiang and the father, Tian Tian, are on a 10-year loan from China.

Book 6Unit 4Global warmingⅠ.阅读理解(2018·河北保定二模)Given the recent interest in green buildings in the media，let’s think differently.Instead of focusing on increasing the supply of energy，what if we focus on reducing demand?Can we start with ending the open-door practice of street-front shops? While cool air from these shops is refreshing to pedestrians，it carries a cost.Energy is used in the air conditioning process.So it must be possible to look for changes in regulations that would encourage more energy-saving designs.For instance，if we fix ceiling fans，air-conditioning homes could surely be avoided for part of the year.Ceiling fans use far less energy.They were common in buildings before air conditioners were available.I wonder how many hours in a year air conditioners could stay if ceiling fans were fixed.In homes built under the small-house policy in New Territories，the ceiling may be too low for ceiling fans.If the 9-meter maximum building height regulation were relaxed，ceiling fans could be fixed to reduce energy use.Current thinking in sustainable building design and operation involves integrated(协调统一的) design；that is，bring together all parties to create a building with better performance that achieves energy reduction.For integrated design to succeed，all parties must come together and think beyond each person’s circle of influence.Better solutions are impossible to avoid with integrated design.Buildings would no longer be engineered after the basic architecture was built.Positive project outcomes may include reduced air-conditioning load，reduced power use for electric lighting，and a reduction in the amount of materials used.We need to ask if we are ready to look beyond our own small circles and seek an improved approach to building design.By that I mean an integrated design resulting in more sustainable buildings.1.What’s the author’s attitude towards the open-door practice of the street shops?A.Supportive.B.Disapproving.C.Optimistic.D.Uncaring.答案B解析观点态度题。

Unit4 Global warming-语法篇____________________________________________________________________________________________________________________________________________________________________1.掌握it在强调句中的用法；2.能够利用这个语法点进行遣词造句并运用到写作中；it的用法—强调句型一、强调句型的基本用法英语中常用的强调句型是：It is / was + 被强调部分(主语、宾语、状语) + that / who / whom + 其他部分。

一般来说，被强调部分指人时，用who或whom，其他情况用that，但that也可指人。

现在用强调句型强调下面这个句子的主语、宾语和状语。

She met John at Mary’s birthday party last Sunday.→It was she who / that met John at Mary’s birthday party last Sunday. (强调主语)→It was John Whom / that she met at Mary’s birthday party last Sunday. (强调宾语)→It was at Mary’s birthday party that she met John last Sunday. (强调地点状语)→It was last Sunday that she met John at Mary’s birthday party. (强调时间状语)温馨提示：1.it为引导词，本身没有词义，仅起引导强调句式的作用；2.若强调的主语是人时，常用who，间或用that，若强调的宾语是人时，多用whom / that；3.在强调状语时，用that；4.在强调结构时，无论被强调的是人还是物，是单数还是复数，be动词一律用单数形式is / was,如果原句中的谓语动词是过去时态，就用was，若是现在时态或将来时态，就用is，也可用情态动词+ be形式；5. 判断一个句子是否是强调句型的方法：如果将句中的It is / was… that / who / whom…去掉，仍能还原为一个完整的句子，那么此句就是强调句。
