For the first time, scientists have recently linked global warming to powerful hurricanes like Katrina, more severe and longer droughts, less snow in many areas, stronger winds, and (at least in northern part of the earth) heavier rain. According to the current rate of giving off CO2, the earth will warm another 4°to 7°vs. the total 1°temperature increase in the last century.
There are some changes we can make in our daily lives – beginning now – to help address the climate crisis.
What We Can Do
1. Buy organic to support sustainable farming, which uses less fossil fuels than traditional farming and also helps to prevent soil becoming poorer and poorer. Not only are the pesticides (杀虫剂) in traditional foods risky for consumers and the environment, but producing and shipping pesticides also use more fossil fuels.
2. Eat more organic plant foods, which require less energy to produce than animal foods. Plant farming also uses less water, and creates less pollution in our rivers and ecosystems. Organic corn and soybean yields are higher than traditional yields in drought situations. For example, traditional soybean production is 20 percent less efficient than organic soybean.
3. Replace standard light bulbs with CF bulbs. Every replaced bulb cuts nearly 1,300 pounds of greenhouse gas. A CF bulb uses only about one-fourth the energy of an incandescent bulb (白炽灯泡)。Australia’s government announced recently that it plans to ban incandescent bulbs within three years. If you’re using a traditional 60-watt bulb, try replacing it with a 15-watt CF bulb.
4. Recycle and reuse aluminum, glass, metal, paper, and plastic to save energy.
47. The underlined word “address” in Paragraph 2 probably means “__________”.
A. place emphasis on B. be aware of
C. deal with D. discuss about
48. We learn from the passage that sustainable farming __________.
A. does not use fossil fuels at all B. can keep soil in good condition
C. leaves fewer pesticides on crops D. costs less than traditional farming
49. Why does the author suggest having more organic plant foods?
A. They are free of pollution. B. They are more efficient to produce.
C. They are safe to eat. D. They are richer in nutrition.
50. We can infer from the passage that a 30-watt CF bulb works as well as traditional __________.
A. 45-watt bulb B. 60-watt bulb C. 100-watt bulb D. 120-watt bulb
