A. patented most types of human genetic materials
B. could obtain legal rights to separated human genes
C. failed to get any patents related to genes
D. were banned from gene research
题目解答
答案
题目分析
首先,我们需要理解题干给出的信息:
- 题干原文: "Companies had won patents for isolated DNA for decades – by 2005 some 20% of human genes were patented. But in March 2010 a judge ruled that genes were unpatentable."
- 中文释义: 几十年来,公司已经为分离的 DNA 赢得了专利——到 2005 年,大约 20% 的人类基因获得了专利。但在 2010 年 3 月,一位法官裁定基因是不可专利的。
- 问题: "It can be inferred that before 2010's ruling, biotech companies ____."(可以推断,在 2010 年裁决之前,生物技术公司____。)
我们需要根据题干信息,推断出在 2010 年法官裁定“基因不可专利”之前,生物技术公司的情况。
选项逐一分析
-
A. patented most types of human genetic materials(为大多数类型的人类遗传物质申请了专利)
- 题干中提到“到 2005 年,大约 20% 的人类基因获得了专利(some 20% of human genes were patented)”。20% 显然不能算作“大多数(most)”。
- 因此,A 选项与题干数据不符,排除。
-
B. could obtain legal rights to separated human genes(可以获得分离的人类基因的合法权利)
- 题干第一句指出“Companies had won patents for isolated DNA for decades(几十年来,公司已经为分离的 DNA 赢得了专利)”。“isolated DNA” 即“分离的 DNA”,也就是“separated human genes”。
- 获得专利(won patents)意味着公司拥有了这些基因的合法权利(legal rights)。而在 2010 年裁决之前,这种专利是有效的。
- 因此,B 选项符合题意。
-
C. failed to get any patents related to genes(未能获得任何与基因相关的专利)
- 题干明确说明“by 2005 some 20% of human genes were patented(到 2005 年,大约 20% 的人类基因获得了专利)”,这说明公司确实获得了相关专利。
- C 选项与题干事实完全相反,排除。
-
D. were banned from gene research(被禁止进行基因研究)
- 题干中并未提及任何关于禁止基因研究的内容。相反,公司能够申请基因专利,说明他们正在进行相关研究。
- D 选项属于无中生有,排除。
结论
通过分析可知,在 2010 年裁决之前,生物技术公司可以为分离的人类基因(isolated DNA)获得专利,即拥有合法权利。
正确答案是:B. could obtain legal rights to separated human genes
