11、 问题:Climate change has been blamed for killer hurricanes, sea level rise, anddrought, but a new report suggests the effects of climate change might hit theworld’s caffeine supply. Up to 70 percent of the world’s coffee supply could bethreatened over the next 68 years, according to a new study by researchers atEngland’s Royal Botanic Gardens.Nearly 100 percent of the world’s Arabica coffee growing regions couldbecome unsuitable for the plant by 2080, according to the study, published in PLOSONE. Beans from Arabica coffee plants account for about 70 percent of theworld’s coffee, but the plant has to be grown under strict weather conditions:They thrive at temperatures between 64 and 70 degrees Celsius, and are highly susceptible(易受影响的) to frost or temperatures higher than 73 degreesCelsius.With temperatures estimated to increase by between 1.8 and 4 degreesCelsius by the end of the century, the fragile(脆弱的) plant might become increasingly expensive and difficult to grow,especially in places such as Ethiopia and Kenya. In that worst-case scenario,nearly all of the world’s native Arabica coffee would die out. Under moreconservative estimates, about 65 percent of the regions that used to grow thecoffee would become unsuitable for it. The evidence from coffee farmers, fromnumerous coffee growing regions around the world, is that they are alreadysuffering from the influences of increased warming.Some commercial farmers would likely be able to move their operations toother areas or would be able to overcome climate change with artificial coolingtechniques, but wild Arabica is generally considered to be much more suitablefor making high-quality coffee.If Arabica becomes impossible to raise in its native areas, it couldwreak havoc on the economies of the mainly third-world countries in which itgrows. Coffee is the world’s most popular drink and is the second most-tradedcommodity in the world, behind oil.“Our modeling shows a profoundly negative trend for the futuredistribution of indigenous(本土的). Arabica coffee under the influence of accelerated global climatechange,” the study says. “Production is likely to decrease significantly incertain areas, and especially in locations that are presently marginallysuitable for coffee production.”Q: What can we learn about Arabica coffee plants fromthe second paragraph? 
选项:
A:The growth of Arabica coffee plants requires strict weather conditions.
B:The flavor of Arabica coffee is better than other’s. 
C:The Arabica coffee plants grow in the areas more subject to climate changes.
D:The Arabica coffee plants produce more coffee beans than other coffee plants.
答案: 【The growth of Arabica coffee plants requires strict weather conditions.

12、 问题:Q: What can be predicted about the future of Arabica coffee by the end ofthe century?
选项:
A:It will extinct throughout the world.
B: It will cause coffee farmers to go bankrupt.
C:It might become more high-priced than ever before.
D:It might be blooming everywhere in Ethiopia and Kenya.
