标题: 请哪位前辈帮助提示一下，多谢了！

At an enormous research cost, a leading chemical company has developed a manufacturing process for converting wood fibers into a plastic. According to the company, this new plastic can be used for, among other things, the hulls of small sailboats. But what does the company think sailboat hulls used to be made of? Surely the mania for high technology can scarcely go further than this.

1.The author’s opinion of the manufacturing process described in the passage is based primarily on the fact that

(A) plastic is unlikely to be durable enough for high-quality sailboat hulls

(B) the research costs of developing the process outweigh any savings possible from the use of the plastic

(D) hulls for small sailboats can be made from wood without converting it into plastic

(E) many other spheres of human activity are in far greater need of technological research

答案是D

2.Which of the following, if true, would most seriously weaken the author’s conclusion?

(A) The plastic produced by the process is considerably lighter, stronger, and more watertight than wood.

(B) The wood used in producing the plastic is itself in increasingly short supply.

(C) The cost of the manufacturing process of the plastic increases the cost of producing a sailboat hull by 10 to 15 percent.

(D) Much of the cost of the research that developed the new process will be written off for tax purposes by the chemical company.

(E) The development of the new plastic is expected to help make the chemical company an important supplier of boat-building materials.

答案是A

我想全文的关键就是这句developed a manufacturing process for converting wood fibers into a plastic.，那么现在小帆船的外壳可以用塑料来做应该就是说这个外壳以前是用木头来做的，这样就通了。我的感觉就是原来是座桥已经铺好了，你现在就是再走回去的感觉，我说不好，让牛人来醍醐灌顶吧，你选的A说塑料不能用来制作外壳，因为他不能durable，首先我觉得这个durable是新信息，原文没有的，而且也跟原文无关啊

这个题目有点怪异啊...是哪里的题目?

不过虽然怪异..思路还是一样的, 注意体会文章的意思

文章说:

1). 某公司花了很多钱, 研究出可以把木头变成塑料

2). 这种塑料可以用来造船

3). (想想船以前是用什么造的?) [看看这个, 联系结论, 很容易回答这个问题, 是木头造的...]

结论, 嗯..这个结论还不好翻译了...但是意思容易理解, 就是说, 不支持这种技术狂热, 意思就是说这个技术没用

问题1: 作者观点建立在什么事实上, 这是一个assumption题目, 就是需要一个条件, 来帮助结论的得出

D, 很明显, 如果船之前是木头做的, 现在费了半天力气, 把木头搞成塑料, 纯粹是浪费嘛...所以可以帮助结论的推出

A, 意思就是塑料造不了高质量的船, 无关, 文中没有说高质量的船啊, 只是说船, 就算造不了高质量的船, 普通质量就够了啊, 如果这种塑料可以极大的降低普通船的制造成本, 那就是有用的技术, 怎么能说是技术狂热, 技术无用呢?

问题2: 削弱结论, 作者说技术无用, 找一个说技术有用的就行了

A, 说这种塑料比木头有优势, 那么, 虽然之前船是木头造的, 虽然这种塑料来源于木头, 但是性能提高, 所以技术游泳, 削弱结论, 是答案

B, 能造塑料的木头越来越少, 原料少了, 那么就没办法造这种塑料, 所以这个技术就是没用的技术, 加强结论, 说明技术无用
