题号：655难度：Easy

　　Loss of the Gocha mangrove forests has caused coastal erosion, reducing fish populations and requiring the Gocha Fishing Cooperative (GFC) to partially fund dredging and new shore facilities. However, as part of its subsidiary businesses, the GFC has now invested in a program to replant significant parts of the coast with mangrove trees. Given income from a controlled harvest of wood with continuing replanting, the mangrove regeneration effort makes it more likely that the cooperative will increase its net income.

　　Gocha红树林的森林流失导致海岸线受到侵蚀，减少了鱼的数量，以及需要Gocha捕鱼合作社GFC为疏浚和开发新的海岸设备提供部分的资金支持。然而，作为一项其附属业务，现在GFC 开始投资一个计划去将红树林重新移植到海岸的大部分地区。考虑到从木材收获和持续移植中都会有一定的收益，因此红树林的再移植是可以给当地的捕鱼合作社增加净收益的。

　　解析：下面哪一个如果正确的话可以最支持上述的推断——红树林的再移植是可以给当地的捕鱼合作社增加净收益

　　解析：这道题围绕的话题在于income

　　Fact: 红树林流失——海岸线侵蚀——鱼减少——GFC要对捕鱼业提供资金支持

　　Infer: 在海岸线移植红树林——木材和持续移植带来收益——GFC会因此增加净收益

　　新题讲解

　　Which of the following, if true, would most strengthen the argument that mangrove replanting will increase the Gocha cooperative’s net income?

　　A. The cost of dredging and shore facilities was shared with the local government.

　　疏浚和设备的花费是和当地政府共同承担的，该选项的内容与上文推断内容无关，可以排除。

　　B. The GFC will be able to hire local workers to assist with the mangrove replanting.

　　GFC将可以去雇佣一些当地的工人去进行红树林的移植，与net income无关，可以排除。

　　C. The GFC derives 10 percent of its revenue from salt-production facilities in an area previously cleared of mangroves.

　　GFC10%的收入来源是之前被砍伐的红树林地区的盐业生产设备，如果这句话是对的，那重新移植红树林是有可能会减少GFC的收入的，故排除该选项内容。

　　D. Mangrove forests tend to increase the commercial fish populations in coastal fishing grounds.

　　红树林会增加沿海地区养殖鱼的数量，增加鱼的数量，自然会增加GFC的income，因此该选项为正确答案。

　　E. A controlled harvesting of mangrove wood by the GFC would have little effect on coastal erosion.

　　GFC对红树林数量的控制几乎不会对海岸线侵蚀带来什么影响，该选项没有涉及到income，可以直接排除。
