Don't rely on plankton to save the planet

Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ___1___.

Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ___2___.

Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. ___3__.

In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere-- just 0.2 percent of the carbon dioxide humankind spews out each month.

Rough estimates in the past have predicted similarly disappointing results. __4__ Says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same. ___5___."

A. Its opponents argue, however, that it will stop global warming.

B. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.

C. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.

D. They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.

E. "These are newer and better models,"

F. Ocean fertilization is not the answer to global warming.

答案及解析

1. B. 线索：前句的句意（可以直接借助句子中的核心结构判断句子大意-- 一些人鼓励浮游生物在海洋里生长，认为这有希望从大气中去除二氧化碳），B中的opponents fear和空格前句中的some..encourage形成语意对比。考点：句子之间的逻辑发展。

2. C. 线索：空格前句句意（微小生物体在水中吸收溶解的二氧化碳，而水中被吸收的二氧化碳又会被空气中的二氧化碳所替代）考点：句子之间的逻辑发展

3. D.线索：代词they 的指代（Jorge Sarmiento from Princeton and his colleagues）和句意上的承接（空格前句说Jorge Sarmiento 和他的同事们研制出一个复杂的计算机模型来分析..因素的影响…。D接着说他们发现100年以后..（100年以后的结果只能通过模拟发现））考点：代词they 的指代和句子之间的逻辑发展

4. E. 线索：空格后句中的动词“Says”暗示“引文”内容考点：句子结构之间的逻辑关系

5. F.线索：空格位置（文章最后一句）暗示该句句意的特点--往往是总结，概括句。对比剩下的选项A和F，选择F。考点：句子之间的逻辑发展
