问题 According to the author, applying biotechnology to industry
According to paragraph 4, ______.
选项 A、the prospect of biotechnology industry depends on its marketing cost.
B、fuel cells are easier to be utilized in auto industry than biofuels.
C、biofuels will replace the fuel cells in the near future.
D、the price of bioplastics shows a downward trend.
答案D
解析 本题问由第四段可得出什么结论。第四段第三、四句谈到"Already，the price of bioplastics overlaps the top end of the petroleum-based plastics market．Bulk production should bring prices down…"，可见生物塑料的价格正在逐步下降，故"生物塑料的价格表现出下降的趋势"正确。生物技术工业的前景依赖于它的营销成本：第四段首句谈到"All this will，in the end，depend on costs"，这里的costs应该指所有成本，尤其是生产成本，文中并没有强调营销成本。在汽车工业，燃料电池比生物燃料更容易利用：与文意相反。在不久的将来生物燃料将取代燃料电池：过度引申。文中虽谈到生物燃料的优势，但是并没预测它很快就会取代燃料电池。
