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。

Unit 4 Global warming单元综合测评(时间:100分钟分值:120分)选择题部分Ⅰ.阅读理解(共两节,满分35分)第一节(共10小题;每小题2.5分,满分25分)阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。
AThe number of buses, taxis and other vehicles on Kenya’s roads is growing every day. Now, the country’s first electric-powered motorbikes are coming into the market. The bike is designed to cut down on pollution and aimed at low-income communities. Most motorbikes used in Kenya depend on gasoline as fuel, but not this new motorbike.Three university students developed the new ecotype bike. It catches the sun’s energy, stores it in batteries and uses it to charge the electric motor. Robert Achoge is one of the student inventors. “Our hope is that by th e fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to conserve the environment and provide affordable transport.”The students have set up a charging station for the motorbikes in Nairobi. Riders can plug the bikes into any electrical outlet. The small battery can run for 70 kilometres when fully charged. Once the power is used up, the motorbike has to return to the station while another charged battery is connected to the bike. The US African Development Foundation (USADF) is providing finance for two solar-powered charging stations in the Kenyan port of Kisumu.Each ecotype bike costs about $700. One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline. “When it comes to buying gasoline, there’s no need. It’s basically good for various things. As long as you won’t take quite a heavy load(装载量), you can go with it anywhere. Otherwise, it may break down halfway. But now people still have a preference to the gas-powered bi kes.”A Nairobi dealership is selling the ecotype bikes. Businessman Kennedy Kusimba hopes they will become popular. We also know they are more reliable compared to the gas-powered bikes.1.What do we know about the ecotype bike?A.It was developed by the USADF.B.Its energy comes from the sunlight.C.It can charge itself while running.D.It does more harm to the environment.2.What do people think of the ecotype bike?A.It’s better not to use it to carry too much.B.It is a good choice for the long-distance journey.C.It will take the place of gas-powered bikes soon.D.It is much more expensive than a traditional motorbike.3.Where does the text probably come from?A.A research plan.B.An advertisement.C.A government report.D.A science magazine.BSeveral years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Former Mayor Richard Daley later decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual demonstration farm for hydroponics(水培).The farm is on a boat called the Science Barge. Rainwater and purified river water are used to grow lettuces, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.Experts say green roofs usually do not get much above twenty-seven degrees Celsius. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.Earlier in 2008, researchers in Texas reported that green roofs can reduce a building’s air conditioning costs by about one fifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers said the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.4.The author writes Paragraph 1 to .A. tell us what is the green roof designB. tell us Germany is the country that leads or guides the green roof designC. introduce some famous hotels in the worldD. lead to the topic of the passage5.The underlined word “storming” in Paragraph 2 can be replaced by “”.A. attackingB.controllingC.attractingD.managing6.According to the passage, which conclusion is WRONG?A. Sometimes green roofs may break down the house.B. Not all the green roofs can reduce the building’s air conditioning costs equally.C. Different designs of green roofs have different effects on buildings.D. Sedums are a kind of plants native to Texas.CThe Antarctic’s ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar region, invading (入侵) plants and insects, including the flies, cause a major threat.More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃over the past three decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before—providing potential green homes for invaders.“The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native life forms.”The Antarctic has several native species of insects. Together with its native mosses, these are now coming under the increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of the Antarctic.In 2015, more than 38,000 tourists visited the Antarctic. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgson.More and more invasive insects and plants have been found on the Antarctic and have required removal. “The insects and plants that are native to the Antarctic have survived there for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”7.What does the underlined word “mosses” in Paragraph 2 refer to?A. A kind of plants.B. House flies.C. Coastal areas.D. A kind of animals.8.What is the main cause of the Antarctic going green?A. Scientists’ coming.B. Global warming.C. A growing number of visitors.D. The rapid spread of native planting.9.What do we know about the house flies in the Antarctic?A. They are native to the Antarctic.B. They will disappear due to the cold climate.C. They seriously affected the Antarctic native species.D. They directly fly to the Antarctic from nearby islands.10.What’s the best title for the text?A. The Antarctic is faced with various threatsB. The Antarctic is becoming green and energeticC. More and more scientists get to explore the AntarcticD. Global warming has caused the temperature in the Antarctic to rise up第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

4.判断强调句的方法 判断一个句子是否是强调句,可把“It is/was”和“who/that”去掉,剩 余部分如果是一个完整的句子,那么这个句子是强调句,否则不是。 试比较下列句子,判断是强调句还是其他句型。 ①It was you and Tom that didn’t come yesterday. 句型:强调句 分析:去掉“It was”和“that”后,句子变成“You and Tom didn’t come yesterday.”结构完整,所以是强调句。 ②It is strange that they didn’t come yesterday. 句型:主语从句 分析:去掉“It is”和“that”后,句子不完整,所以不是强调句。本句 中It作形式主语,that引导真正的主语从句。

Unit4 写作课名师教学设计Module 6 Unit 4 Using Language--Writing教学设计1. 学情分析Learning situation:In BOOK6 UNIT4, although students have already learned some knowledge about global warming in the previous reading part, they still have some difficulties in expressing ideas on how to reduce global warming in their daily life. Besides, for the writing task, students have known something about how to write a letter of advice, but most of them still don’t know the structure of it clearly, which may cause some confusion in their writing. So they need more guidance and some proper help on how to give suggestions on such big a social problem--how to reduce global warming.2 重点难点Difficult points and important points:Students may have difficulty analyzing which key information should be included in the letter and how to make use of some good sentence-patterns of suggestions. So students may have difficulty using their own words for the output part.3 教学过程3.1 第一学时3.1.1教学目标Teaching goals:1. Language competences: Students will be able to(1)learn some new words in situations: global warming, carbon dioxide, the rise of the sea level, cause, make a difference, count.(2)learn the structure of a letter of advice.(3)learn how to express themselves by using proper sentence-patterns of suggestions.2. Learning competence:The class is based on the students-centered principle, so every student is encouraged to participate in all the steps of writing. The teacher is just a guide, who will adopt some skills to get students to think about one question in the whole class---how canwe write a letter of advice on a social problem well? After all these activities, students will be able to exchange their ideas and learn how to organize a letter of advice.3. Cognitive competence:Students will be able to think about the structure of this kind of letter critically and they will form a right attitude towards the problem of global warming, which will exert some positive effects in their daily life.4.1.2 学时重点与难点Difficult points and important points:Students may have difficulty in analyzing the key information before writing and failing to adopt some good ways to express their opinions.4.1.3 教学活动活动1【导入】Greetings＆Lead inEnjoy a short video1.
