Natural rubber is obtained from rubber as a white, milky liquid known as latex (橡浆). This is treated with acid and dried, before it is sent to countries throughout the world. As the rubber industry developed, more and more rubber was required. Rubber plantations (种植园) were set up in countries with a hot, humid climate, but these still could not supply sufficient raw rubber to satisfy the requirements of developing industry.It was unsatisfactory for industry to depend on supplies coming from so far away from the industrial areas of Europe. It was always possible that supplies could be stopped by wars or shipping trouble.For many years, attempts were made to produce a substitute, but they were unsuccessful. Finally, a method was discovered of producing artificial rubber which is in many ways superior and in some ways inferior (劣的) to natural rubber. Artificial rubber is produced in factories by a complicated chemical process. It is usually cheaper than natural rubber. At present, the world requirements for rubber are so great that both natural and artificial rubbers are used in large quantities.(sing-0.5) Compared with artificial rubber, natural rubber is ________.A superiorB cheapC inferiorD expensive

题目解答

答案

根据文章，人工橡胶在许多方面优于天然橡胶（superior），但在某些方面不如天然橡胶（inferior）。同时，人工橡胶通常更便宜（cheaper），而天然橡胶更贵（expensive）。题目未限定具体方面，综合分析，天然橡胶与人工橡胶相比，最显著的特点是“expensive”。 A项“superior”不完全准确，因天然橡胶在某些方面更优。 B项“cheap”与文不符，人工橡胶更便宜。 C项“inferior”未涵盖全部内容。 D项“expensive”最符合文章表述。 答案：D. expensive

解析

本题考查对文章细节信息的理解和推理能力。解题的关键在于准确把握文中关于天然橡胶和人工橡胶特点的描述，并对各选项进行细致分析。

  1. 分析选项A：
    • 文中提到“a method was discovered of producing artificial rubber which is in many ways superior and in some ways inferior to natural rubber”，这表明人工橡胶在很多方面优于天然橡胶，同时在某些方面不如天然橡胶。
    • 所以不能简单地说天然橡胶比人工橡胶“superior（更优）”，选项A不准确。
  2. 分析选项B：
    • 文中明确指出“It is usually cheaper than natural rubber”，这里的“it”指代人工橡胶。
    • 这说明人工橡胶通常更便宜，而不是天然橡胶便宜，选项B与原文不符。
  3. 分析选项C：
    • 虽然人工橡胶在某些方面不如天然橡胶，但不能仅依据这一点就说天然橡胶比人工橡胶“inferior（更差）”，因为天然橡胶也有不如人工橡胶的地方。
    • 所以选项C不全面。
  4. 分析选项D：
    • 由“It is usually cheaper than natural rubber”可知，人工橡胶通常更便宜，那么相对而言，天然橡胶就是“expensive（昂贵的）”。
    • 选项D符合文章表述。
