Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetables. Without urgent help, the country’s days are numbered.But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 2050cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 13 degrees over the next 100 years.Warmer weather makes glaciers (冰川 ) melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 1025 cm in the last 100 years.The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter thiscentury.Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.1. We can infer from the second paragraph that________.A．Tuvalu is in danger of being swallowed up by the seaB．all Tuvalu’s islands are about five meters above the sea level C．drinking water in Tuvalu has been destroyedD．Tuvalu is often flooded by storms and waves2．The author uses Tuvalu and Venice as examples in order to explain________.A．they are the first place sinking into the seaB．they are both sinking into the mud where they standC．they will disappear in the futureD．their trouble is caused by the global warming3．Put the following events in the right order.a．Glaciers began to melt.b．People burn coal, oil and gas.c．The greenhouse effect is growing.d．The earth is getting warmer and warmer.e．The sea level is rising.f．More CO2 is produced.g．Many places are sinking into the sea.A．d, f, b，c, a, e, g B．b, f, c, d, e, a, gC．f, c, b, d, a, e，g D．b, f, c, d, a, e, g4. What does “climate refugees” mean?A．People who are forced away from their homeland by climate.B．Climate changes.C．Rare animals.D．Climate effect.5. Which of the following is NOT true according to the passage?A．Tuvalu’s nine little islands are less than five meters above the sea level.B．The average global temperature has risen by 13 centigrade degrees over the past 100 years.C．The warmer temperature causes the sea level to rise.D．There will be huge climate changes unless the warming is stopped.BBEIJING, China —Pollution in China remains very serious as the country’s rapid economic growth brings new environmental problems, a minister said Saturday.Vice Environment Minister Zhang Lijun said China has made progress on environmental protection, but admitted that its rapid economic growth over the past decade has had a negative effect on the environment.“Our rapid economic development has continuously brought our country new environmental problems, particularly dangerous chemicals, electronic waste and so on. These environmental pollutants (污染物) bring new problems and affect human health，” Zhang told a news conference.He said that emissions (排放) of traditional pollutants remain high and some areas have failed to meet government standards.The minister noted that rapid development in the next five years would increase the need for China to improve environmental protection and shift to a more sustainable(可持续的) model of economic development from its dependence on industries which consume huge quantities of energy.China is focusing on clean energy, including solar, wind and nuclear power, as one way to reduce its dependence on coal, which generates threequarters of its electricity and is also used for winter heating in northern cities. China also hopes the strategy will reduce its demand for oil and gas and increase economic growth and jobs.Zhang told reporters there was no plan to adjust China’s overall strategy for nuclear development but he said Beijing will learn lessons from Japan after a violent earthquake resulted in a radioactive leak (放射能泄露)．“Some lessons we learn from Japan will be considered in the making of China’s nuclear power plans，” he said. “But China will not change its determination and plan for developing nuclear power.”6．According to the minister, the pollution problem requires China to________.A．slow its economic developmentB．ask industries to meet government standardsC．protect the environment firstD．transform its economic development model7.According to the text, which of the following is TRUE?A．Rapid economic growth helps to improve the environment.B．Dangerous chemicals are one of the traditional pollutants.C．Coal is used more in northern cities than in southern cities.D．The use of clean energy will help increase job opportunities.8．The underlined word “generates” in Paragraph 6means“________”．A．reduces B．transports C．produces D．needs9. What do the last four paragraphs mainly talk about?A．Japan had a violent earthquake recently.B．China will learn to use nuclear power from Japan.C．Rapid economic growth caused some problems in China.D．China’s economic development will shift to depend on clean energy.10. What is Zhang’s attitude towards what happened in Japan?A．He is astonished at it and feels pity for the Japanese people.B．He thinks Japan should do something to prevent it happening again.C．He thinks China will pay more attention to nuclear safety.D．He doe sn’t think it will affect China’s nuclear power plans at all.参考答案：Ⅰ.选词填空1. subscribe2. quantities3. tend4. opposed5. state6. range7. glanced8. steady9. random10. consequencesⅡ.单项填空1. 解析：选C。

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。

Unit4Globalwarming阅读理解组块专练——练速度(限时：30分钟)Ⅰ.阅读理解AIn many parts of Africa, communities have electricity service t hat sometimes does not operate.And many rural (农村的) settlements are cut off from electricity producing centers.T herefore, offgrid (离网) solar power is becoming available to many communities.O ffgrid solar energy is energy that is captured from the sun wit hout being connected to a main electricity center.The Internati onal Energy Agency says more than 600 million people in Afri ca have no way to get electricity.New technology, however, c ould help solve this problem.Lumos Global is among the companies offering solar energy s ervices in Nigeria.The company's Chief Operating Officer, Nir Marom, says, “You need to put the system on the roof, and pu t the indoor unit in the home.There is a cable (电缆) to connect them.You don't need to be an electrician or any thing like this.The sun charges the electricity, but you need toprovide the credit to power the system up, and you do this usi ng your mobile phone.” The price of offgrid solar energy syste ms has decreased sharply.Today, people can rent solar equip ment for less than 50 cents a day.And they can pay for the ele ctricity as they need it.Senegal opened one of Africa's largest solar factories last yea r.The company paid for the construction of the solar factory in Senegal.A manager says a solar farm in Senegal can produc e twice the amount of electricity that a farm of the same size i n Britain or in northern France could produce.The Internationa l Energy Agency predicts that almost a billion people in subSa haran Africa will have ongrid electricity by 2040.But the agenc y says 50 million people will still be offgrid.Investors believe s olar power could serve those people while also helping to red uce gases linked to climate change.语篇解读：本文是一篇说明文。

Unit 4 Global warming Section Ⅲ Grammar-it的用法（2）①There is no doubt that the earth is becoming warmer and that it is human activity that has caused this global warming rather than a random but natural phenomenon.②It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997.③They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide.④It was during the 20th century that the temperature of the earth went up about one degree Fahrenheit.[我的发现]这些句子都是强调句，句中的黑体词部分标出了句中的强调句结构，即：it_is/was＋被强调部分＋that/who ...句首词用“it”；be动词总是用单数形式，即is或was。
连接词一般用that，当强调部分是人时，强调连接词也可用who。
一、强调句的基本用法强调句就是把句中要强调的部分(通常是主语、宾语、状语或状语从句)放在It is/was 和that/who之间，原句中剩余部分放在that/who之后。
1．强调句的陈述句式“It is/was＋被强调部分＋that/who＋其他剩余部分．”The 2022 Winter Olympic Games will take place in Beijing and Zhangjiakou.→It is in Beijing and Zhangjiakou that the 2022 Winter Olympic Games will take place.在北京和张家口将要举行2022年冬季奥运会。
[名师点津] (1)强调句中的连接词只用that(指人或物)或who(只指人)，且都不可省略。
(2)强调句可以强调主语、宾语和状语，但不能强调谓语，强调谓语动词要用do/does/did＋动词原形。
He did write to you last week.上周他确实给你写了信。
2．强调句的一般疑问句式“Is/Was it＋被强调部分＋that/who＋其他剩余部分？”Is it in Beijing and Zhangjiakou that t he 2022 Winter Olympic Games will take place?是在北京和张家口将要举行2022年冬季奥运会吗？3．强调句的特殊疑问句式“被强调的疑问词＋is/was it＋that＋其他剩余部分？”What's it that Professor Liu teaches us this year?刘教授今年到底教我们什么？How is it that she turned down our help?什么原因使得她拒绝我们的帮助的？When and where was it that you got to know Mary?究竟在何时何地你认识的玛丽？Who was it that came up with the bright idea?究竟是谁提出了好的主意？4．强调句的识别方法如果把强调结构去掉，句子的意思是完整、清楚的，句子结构也是完整的，这个句子就是强调句。
如果把强调结构去掉后，意思不通顺，结构也不完整，则句子不构成强调句式。
It was because he refused to obey the policeman that he was sent to the police station.他是因为拒绝服从警察而被送到警察局的。
把强调结构去掉，则变为：He was sent to the police station because he refused to obey the policeman.因为他拒绝服从警察，所以被送到了警察局。
去掉强调部分后，句子结构和意义仍然完整，说明这是个强调句。
[即时演练1](1)句型转换They met each other in that supermarket.①It_was_in_that_supermarket_that they met each other. (强调原句中的地点状语)②Was_it_in_that_supermarket_that they met each other? (把①变为一般疑问句)③Where_was_it_that they met each other? (提问①句中的地点状语)(2)用适当的连接词填空①(2015·湖南高考改编)It was when we were returning home that I realized whata good feeling it was to have helped someone in trouble.②(2014·湖南高考改编)It's not doing the things we like, but liking the things we have to do that makes life happy.③(2014·四川高考改编)Was it because Jack came late for school that Mr. Smith got angry?二、强调句的特殊用法强调句与其他句型的结合，注意以下几种用法：1．强调句型与名词性从句的结合句式特征为：整个强调句型用作名词性从句或者在强调句型中含有名词性从句时，从句要用陈述语序。
Do you know w hat it is tha t they will do next?你知道他们下一步究竟要做什么吗？2．强调句型与定语从句的结合句式特征为：在强调句型的被强调部分或其他部分中找出一个先行词，附上修饰该部分的定语从句，这样整个句子结构就变得非常复杂。
应特别注意不要混淆定语从句的关系词和强调句型中的that/who部分。
It was last Spring when they worked together(when引导的定语从句) that they began to become good friends.是在一起工作的去年的春天里他们开始成为了好朋友。
It was in the school where they had their schooling (where引导的定语从句) that they had a gettogether again twenty years later.二十年后，他们是在曾接受教育的学校里又聚在了一起。
3．强调句型与not ... until句型的结合“It is/was not until＋被强调部分＋that＋其他剩余部分．”It was not until he came back that I knew the result.直到他回来，我才知道结果。
[即时演练2](1)单句语法填空①The question is whom it is that we can turn to for help.②It is in the hotel where he stayed last night that he lost his mobile phone.③(2015·福建高考书面表达)It is not the story itself but what is reflected in the story that counts.(2)补全句子①I've already forgotten where_it_was_that you put the dictionary.我已经忘了你到底把字典放到哪里了。
②It_was_playing_computer_games_that cost the child plenty of time which he ought to have spent doing his lessons.是玩电脑游戏花去了这个孩子大量的应该用在功课上的时间。
③(2013·天津高考改编)It_was_not_until_near_the_end_of_the_letter_that she mentioned her own plan.直到将近信的结尾她才提到她自己的计划。
三、强调句应注意的问题1．即使被强调成分是句中的时间状语、地点状语、原因状语等，也不能用when, where, because等而要用that。
It was in front of the bank that the old lady was robbed.老太太是在银行前面被抢劫的。
2．强调句型中的主谓一致——还原后，由真正的主语来确定谓语动词的形式。
Personally I think it is the sales manager, rather than the sales girls, that ________ to blame.强调句还原：Personally I think the sales manager, rather than the sales girls, ________ to blame.根据主谓一致中的“就远原则”可以判断使用第三人称单数；根据平行谓语动词think，可以确定使用一般现在时，故此处应为is。
3．强调句型的反意疑问句句式“It is/was＋被强调部分＋that/who ..., isn't/wasn't it？”It was Alice and her boyfriend who sent the old man to the hospital, wasn't it?是爱丽丝和她的男朋友把这老人送到医院的，是吗？4．强调句型的省略形式句式特征为：在一定的上下文中，强调句型的某个部分可以省略，解题时要特别注意将其复原并加以比较。
