42) The following is a letter to the head of the tourism bureau on the island of Tria.
Erosion of beach sand along the shores of Tria Island is a serious threat to our island and our tourist industry. In order to stop the erosion, we should charge people for using the beaches. Although this solution may annoy a few tourists in the short term, it will raise money for replenishing the sand. Replenishing the sand, as was done to protect buildings on the nearby island of Batia, will help protect buildings along our shores, thereby reducing these buildings' risk of additional damage from severe storms. And since beaches and buildings in the area will be preserved, Tria's tourist industry will improve over the long term.
Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
结论:We should charge people for using the beaches
证据1:Although this solution may annoy a few tourists in the short term, it will raise money for replenishing the sand.
证据2:Replenishing the sand, as was done to protect buildings on the nearby island of Batia, will help protect buildings along our shores, thereby reducing these buildings' risk of additional damage from severe storms.
证据3:And since beaches and buildings in the area will be preserved, Tria's tourist industry will improve over the long term.
(TS1)To begin with, we need to know about potential tourists' attitudes towards the new policy of charge to see whether this policy would bring enough money for the desired objective. 对收费政策不满的游客可能占很大比例,而且很可能会因为不满因此减少游览的次数,甚至转向同类型的其他岛去游览。如果因此导致很少的人来游览这个岛,筹钱的目的就达不到了。
(TS2)In addition, it is also important to look into the causation of the sand erosion and other enviornment conditions of this island to evaluate the value of replenishing the sand. 这段讲沙滩侵蚀可能是因为游客过多,如果是这样的话收费和补沙有利于解决此问题。但也有可能是环境污染,水土流失或季节特点导致海浪很大。如果是这些情况,补沙的作用只能发挥很短暂的时间。与补沙相比,治理环境、种植树林等等举措就更有价值。
(TS3)Besides, we need evidence that the buildings'conditions along shores of Tria are very similar to those in Batia before taking the suggestion. 这段讲B的沿岸建筑情况和T可能非常不一样,比如B的建筑根基很浅,非常依赖表面的沙子来起固定作用抵抗风暴。而T的建筑根基很深且牢固,与表面有没有沙子没多少关系。这样的话即使不投资补沙,建筑依然完好无损,所以补沙对保护建筑的意义不大,也就对吸引游客的意义不大,甚至可能为补沙修复沙滩的钱不能与增加游客收益的钱相抵。或者T的建筑情况比B的情况遭很多,除了缺少沙子还有建材老旧等问题,即使补了沙子还是不能保证它们不被风暴摧毁。如果是这样的话,补沙与修复、重建建筑相比,就不是最要紧和最明智的选择。
The author of the argument recomends that the Tria Island should charge people for using the beaches to address the problem of sand erosion in that it would help replenish the sand, which has a good effect to protect buildings on the island of Batia, and well preserved beaches and buildings would nourish the local tourist industry. In order to assese the suggestion, we need more information about the potential tourists of the Tria Island, the causation of the beach sand erosion and the conditions of the buildings along the shores both of Batia and Tria Island.
To begin with, we need to know about potential tourists' attitudes towards the new policy of charge to see whether this policy would bring enough money for the desired objective. It's safe to assume that some of them would be annoyed about it. But we don't know what the proportion of these unsatisfied tourists would be and what would result from this dissatisfaction. It's possible that most of the potential tourists of Island of Tria care a lot about the charge. In this case these tourists would at least reduce the frequency of visiting the island, or worsely, turn to some other beautiful beaches where there is no sand erosion without paying, and decide to not come to the Tria Island any longer. If people rarely come to visit the Island because of the charge, it's hard to raise enough money for the replenishing sand project.
