2010年4月份GMAT逻辑真题(04.03)（一）(2)

　　V3学家发现oil的存量在减少，所以预测用绿色新能源发电的比例会有少量增加。但又说，coal的存量很大，还可以用XX年，可以用来发电，但是会造成严重的空气污染。问结论。

　　我选的未来该地区的空气污染会加重

　　8、鸟吃螃蟹

　　V1(from ericphantom)有一个是说鸟吃螃蟹蛋游客看鸟的，政府扩大螃蟹栖息地，问削弱。

　　考古：

　　V1就是一个地方有海滩，上面很多螃蟹(crab)筑巢生蛋(eggs)，有中迁徙的鸟迁徙的时候会中途停留在这里吃这个蛋，然后再迁徙。鸟吃螃蟹蛋成为一个啥景点还是啥的，很多游客来参观。当地政府于是决定做个工程，把海滩延长一倍，以此吸引更多游客。 问削弱。

　　原题答案我依稀记得螃蟹下蛋的数量还是什么跟螃蟹的密度有关(也就是说海滩变成原来两倍，螃蟹密度就小了)。 真记不清了， 楼主谨慎参考

　　V2一种鸟到一个地方栖息，因为这里的蟹都在沙滩上产卵，所以越来越多的鸟在这里聚集，成了游客们的景观。当地政府为了吸引游客，为了吸引更多的鸟，把沙滩扩大，这样就会有更多的蛋，鸟就会更多。问weaken。

　　记得E是说因为地方小，密度高，所以被埋的蛋就容易被蟹不小心弄出来。

　　我也选的E

　　D选项是说建设之后游客对于鸟跟蟹的活动的干扰都降低了。翻成中文很明白，但英文却说的很迷惑。我还在两答案中纠结了一下，大家看到时多注意一下。

　　V3 Mayor: Migrating shorebirds stop at our beach just to feed on horseshoe-crab eggs, a phenomenon that attracts tourists. To bring more tourists, the town council plans to undertake a beach reclamation project to double the area available to crabs for nesting.

　　Birdwatcher: Without a high density of crabs on a beach, migrating shorebirds will go hungry because shorebirds only eat eggs that a crab happens to uncover when it is digging its own nest.

　　Which of the following, if true, would provide the mayor with the strongest counter to the birdwatcher’s objection?

　　A.Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.

　　B.Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.

　　C.On average, tourists who come to the town in order to watch birds spend more money there than tourists who come for other purposes.

　　D.The additional land made available by the reclamation project will give migrating shorebirds more space.

　　E.Some of the migrating shorebirds make only one stop during their migration form South America to Canada.
