共享题干题 （二） 回答下列的问题。 Around 45% of the UK's carbon dioxide emissions come from the energy people use every--at home and when they travel. In order to generate that energy, fossil fuels (coal oil, and gas) are burnt, and these produce greenhouse gases-in particular carbon dioxide (CO2) a year, and it is the same CO2 that is changing the climate and damaging the environment. CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping. Without this greenhouse effect, the average temperature on Earth would be around －18℃, compared with the current average of around +15℃. The composition of this blanket of gases has remained relatively constant for many thousands of years. However, since the industrial revolution began around 200 years ago, people have been burning increasing amounts of fossil fuels, thus releasing more CO2 and other greenhouse gases in the process. This has increased the heating effect of the blanket, trapping more of the sun's energy inside the earth's atmosphere in turn the earth's temperature has increased more rapidly in a shorter penned of there that it has for thousands of years. In 2008, the total UK CO2 emissions were 533 million tones 27% (144 million tons ) of those emissions came from the energy used to heat, light, and power homes. Transport emissions caused by passenger cars, buses and motorcycles accounted for a further 16% (87 million tons ) of the UK's CO2 emissions. These figures show that a significant amount of CO2 results from ordinary citizens' carbon footprint in their daily activities and lifestyle.The effects of climate change can be seen all around us. Weather patterns are becoming more and more fractured and uncertain, and over the last century trends in warm weather have become increasingly common. In the UK in the last 40 years, winters have grown warmer with much heavier rainfall. One of the clearest shifts over the last 200 years is towards summers that are hotter and drier, causing pervasive water shortages. Recent years have been the hottest since records began and during August 2003 the hottest outdoor temperature in the UK was recorded --38.5.1.[不定向选择题]What is the author's opinion about the level of CO2 emissions in the UK?A.The majority of CO2 emissions come from motorized transport. B.CO2 emissions may cause climate change in the future. C.More CO2 emissions come from homes than from cars. D.The average citizen does not create much CO2. 2.[不定向选择题]What is the author's main aim?A.To explain the greenhouse effec B.To describe the effects of climate change in the UK. C.To show how much CO2 is produced by ordinary people's activities. D.To illustrate how industrial activity create the greenhouse effect.

1.参考答案：C
参考解析：根据第三段可知，27%的二氧化碳排放量是源于家庭照明、供暖等，而车辆所造成的二氧化碳排放量占总排放量的16%。因此，C选项“源于家庭的二氧化碳排放比源于车辆的多”符合文意。
2.参考答案：B
参考解析：纵观全文，作者一直在讨论大不列颠联合王国气候变化所带来的影响。所以本题选B。3.[不定向选择题]CO2 emissions from vehicles__________A.are a more serious problem than energy shortage B.do not cause any problems C.are high because the average household owns a car D.contribute considerably to greenhouse gases
