问题 According to the passage, the exhaust from a car engine could probably be checked by______.
What does Jeremy Rifkin and Ted Howard’s statement imply?
选项 A、The commercial applications of genetic engineering are inevitable.
B、American will depend on other countries for biological progress.
C、Americans are proud of their countries for biological progress.
D、The potential application of each new genetic advance should be controlled.
答案A
解析 该题问“Jeremy Rifkin和Ted Howard的话暗示了什么?”一看“imply(暗示)”这个词，我们应该首先明白答案一定不是文章中明明白白写出的句子，而换句话说文章中明明白白写出的句子一定不是答案。选定“Jeremy Rifkin”和“Ted Howard”这两个专有名词为答案线索词，我们在最后一段的第2句中找到答案相关句。该句说“如……一样，大规模的基因工程有可能引入美国。”而备选答案项中A说“基因工程的商业用途是不可避免的”，与原文中相关句的说法相符；而B和C都没有涉及基因——文章的说明对象，所以不可能是答案；而D说“每个新的基因发展的潜在用途都应该受到控制”，可见D的说法太绝对，所以应该不对，故答案是A。
