[单项选择]第二篇：
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
A. To explain the greenhouse effect
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
[填空题]Today atmospheric carbon dioxide concentrations are 31 percent more than that of______.
[填空题]Passage Five
Rising carbon dioxide levels leads to global warming. The industrialized world has been the main protagonist given that carbon dioxide lasts about 100 years in the atmosphere, but as the developing nations become increasingly mechanized and urbanized, the balance is shifting. Indeed, the carbon emissions of Asia more than doubled from 1990 onwards.
[填空题]Carbon is an _____, while carbon dioxide is a compound.
[填空题]Carbon dioxide is not beneficial to the ripening process.
[单项选择]In the atmosphere, carbon dioxide acts rather like a one-way mirror—the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.
According to a weather expert’s prediction, the atmosphere will be 3 ℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also. the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of earth’s chief food-growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in othe
A. the greenhouse effect
B. the solar effects on the earth
C. the models of solar-weather interactions
D. the causes affecting weather
