  28. 螃蟹下蛋(GWD原题)

  V1 from exchange

  GWD17-Q34: 终于没变了= =

  During the month of May, crabs arrive on Delaware’s beaches to lay eggs. Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds. Delaware’s crab population has declined recently. This decline, however, poses no serious threat to the migrating shorebird populations: by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.

  Which of the following, if true, most seriously weakens the argument?

  A. No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.

  B. The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.

  C. There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through.

  D. The crabs do not conceal their eggs.

  E. The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully. (Answer)

  V2 from draco2 (690)

  能力有限只记得一道了,是说某海滨城市海滩上的乌龟下蛋什么的吸引了很多鸟,鸟又吸引了游客,所以为了增加游客,该市计划扩大海滩面积至原来的两倍,考削弱该计划。我选了:这些鸟只有当海滩上的乌龟密度达到一定程度时才会被吸引

  考古

  V1(from chaserJing)有一套题我觉得像是GWD的变体,就是说什么一个鸟在它们迁徙钱要在一个沙滩上要吃一种乌龟的蛋,有很多游客来看,于是这里的政府为了提高旅游收入,吸引更多鸟和游客过来围观这一幕,决定要扩大这个乌龟生蛋的范围,即扩大这个沙滩吧,求削弱:

  我记得这道题我选的的答案貌似是一个跟密度有关的,好像是说地方大了,生蛋的密度就小了,从而会让这些鸟找不到这些蛋什么的,(所以它们在这就不会像以前那样待)

  V2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

  V3一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nada.
