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 patches 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 analyse how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometres 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, fertilising the ocean removes 1 million tonnes of carbon from the atmosphere — just 0.2 per cent 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.1 “But the take-home2 message is the same. 5 ” 词汇： plankton /5plANkt(E)n/ n.浮游生物 tout /taJt/ v.竭力劝说 dioxide /dai5Cksaid/ n.二氧化物 microscopic /maIkrE5skRpIk/ adj.微小的spew /spju:/ v.吐出 注释：
1. the Massachusetts Institute of Technology：麻省理工学院
2. take-home：实得的练习：
A Its opponents argue, however, that it will stop global warming. B Its opponents fear that it 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 per cent of the extra carbon that was originally taken up by plankton had actually been removed from the atmosphere. E “These are newer and better models.” F Ocean fertilisation is not the answer to global warming.
答案与题解：
1. B 本文第一句话说的是，一些人竭力劝说促使浮游生物生长是去除大气中二氧化碳的一种有希望的方法。从“竭力劝说”这个短语中可以推出，不同意这一假设的大有人在。从提供的选项看，只有 A和 B有可能，因为 A和 B都提到了这一假设的反对者。 A说的是：但是反对这一假设的人争辩说，促使浮游生物生长会阻止全球变暖。 B说的是：但是反对这一假设的人担心，促使浮游生物生长会破坏海洋生态系统，并且计算机模型也显示这种办法效果很差。 A实际上是同意一些人所做的假设，所以不对。也就是说 B才是正确的选项。
2. C 第二段前两句的意思是：在海洋的部分水域放人一些铁暂时可以促使浮游生物生长。这些微生物可以吸收溶解在水中的二氧化碳，而水中被微生物吸收了的二氧化碳又可以从空气中的二氧化碳得到补充。下面这句话应当是什么呢 ? C说的是：随着浮游生物的死亡，落在海底后，它们中的碳被假定锁在了海床上。可以看出，此句跟上面两句话很连贯
3. D 第三段的第一句话主要讲 Jorge Sarmiento和他的同事用一个复杂的计算机模型分析诸如海洋化学和水流等因索对这种方法的影响。那么接下来的话应当告诉读者他们分析的结果。 D是这么说的：他们发现，一百年后只有 2%到 11%之间的原先由浮游生物吸收的额外的碳是来自大气的。 D是结果，因此是正确的答案。
4. E这个问题的回答很简单，因为空格后面有“ says”这个词，它预示着所填入的句子应该是带引号的。 E是唯一一个带引号的句子。 E的意思是：这些是比较新的也是比较好的模型。
5. F 昀后一段讲的是：过去一些粗略的估计预测到的都是相似的令人失望的结果，它们提供的核心信息是相同的。即，对海洋施肥不是解决全球变暖的办法。可见 F是正确的。

答案与题解
1. C第二句的前半句说的是“要选定当世最令人叹为观止的奇迹是一个无法完成的差事”，后半句解释“做不到”的原因在于每年都有新的更令人叹为观止的建筑出现。本题要选的词应该是与描述constructions极好性状有关的形容词。四个选项中wonderful符合这个要求，而delightful, useful和careful均与constructions极好性状无关，因此不可能是答案。
2. A be worthy of 意为“值得”。Three giant, structures 值得什么呢?值得我们 passion (热情)、expression(表达)或detection(发现)?这三个选项显然不会是答案。Admiration(赞叹)才是答案。
3. C “the tall twin towers”给出了寻找答案的线索。tall towers意为“高楼”，所以452米指的是高度。
4. B本段叙述马来西亚吉隆坡的国油双峰塔。四个选项中只有architect(建筑师)与设计国油双峰塔最相关。其他三个选项与architect相比，相关性就差多了。
5. D floor之前搭配的介词是on。
6. D本段前面的句子描述了国油双峰塔的建筑特色，本句进而介绍塔的其他两个特色，即double-decker lifts (双层电梯)和glass and steel sunshades(建材为玻璃和钢的遮阳篷)。根据上下文判断，features是答案。
7. A at the time(在那时，那时候)是固定搭配，后接从句。
8. D从词组搭配和上下文意思上判断，reaching over 340m at the highest point是最合适的。 reach a height意为“达到某个高度”，而develop a height(发展某个高度)，expand a height (扩展某个髙度)和stretch a height(延伸某个高度)都不合理。
9. C congestion是解题的关键词。建造髙架大桥的目的是为了缓解交通拥挤，所以选择relieve是理所当然的。
10. A本句是说米约高架桥的坚固程度，它能经受住最极端的地震和气候条件而不会倒塌。本题的答案是most。the most extreme是形容词extreme的最高级形式。
11. B很明显，the River Parana之后是个非限制性定语从句，连接词只能用which。what不能指代the River Parana。that用于限制性定语从句。Who不能指代非生命的the River Parana.
12. A the Itaipu Dam由巴西和巴拉圭两国斥资共建，所以答案不可能是provinces(省),areas (区域)或regions(地区)。countries是理所当然的选择。
13. C建造水电站的目的是利用水能发电，获得电能。Energy是答案。本句的下半句 breaking previous records for energy production 中的“energy”也为答案的选择提供了依据。
14. A iron和steel是物质名词，是不可数的，用the amount of iron and steel是对的。
15. D mainly amazing(主要叹为观止的)，totally amazing(全部叹为观止的)或 rarely amazing (很少叹为观止的)都与句子的意思接不上。只有truly amazing (真正叹为观止的)才符合上下文的意思。
