航空界有个关于飞行安全的“海恩法则”:每一起严重事故的背后,必然有29 次轻微事故和300起未遂先兆及1000起事故隐患。“海恩法则”启示我们( )

A.规律是客观的,我们要善于发现和利用规律

B.量变是质变的前提,质变是量变的必然结果

C.矛盾是普遍的、客观的

D.任何事物之间都存在联系

答案

答案:B

题目分析:每一起严重事故的背后,必然有29 次轻微事故和300起未遂先兆及1000起事故隐患,这句话告诉我们事故并不是陡然发生的,而是从轻微慢慢的演变成严重,积少成多,即量变是质变的前提,质变是量变的必然结果。材料中没有涉及规律和矛盾,AC不选,D的说法错误,因为联系是有条件的,并非任何事物之间都存在联系。正确答案是B。

点评:本题考查考生对知识点的理解情况,哲学的知识点,只是记忆还不能解决问题,一定要理解,在理解的基础上记忆,考生只有理解什么是规律、量变和质变、矛盾,才能根据材料判断出正确的选项。

In 2010, a federal judge shook America’s biotech industry to its core. Companies had won patents for isolated DNA for decades—by 2005 some 20% of human genes were parented. But in March 2010 a judge ruled that genes were unpatentable. Executives were violently agitated. The Biotechnology Industry Organisation (BIO), a trade group, assured members that this was just a "preliminary step" in a longer battle.

On July 29th they were relieved, at least temporarily. A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed holb patents to two genes that help forecast a woman’s risk of breast cancer. The chief executive of Myriad, a company in Utah, said the ruling was a blessing to firms and patients alike.

But as companies continue their attempts at personalised medicine, the courts will remain rather busy. The Myriad case itself is probably not over Critics make three main arguments against gene patents: a gene is a product of nature, so it may not be patented; gene patents suppress innovation rather than reward it; and patents’ monopolies restrict access to genetic tests such as Myriad’s. A growing number seem to agree. Last year a federal task-force urged reform for patents related to genetic tests. In October the Department of Justice filed a brief in the Myriad case, arguing that an isolated DNA molecule "is no less a product of nature.., than are cotton fibres that have been separated from cotton seeds. "

Despite the appeals court’s decision, big questions remain unanswered. For example, it is unclear whether the sequencing of a whole genome violates the patents of individual genes within it. The case may yet reach the Supreme Court.

As the industry advances, however, other suits may have an even greater impact. Companies are unlikely to file many more patents for human DNA molecules I most are already patented or in the public domain. Firms are now studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug’s efficacy, companies are eager to win patents for ’connecting the dits’, explains Hans Sauer, a lawyer for the BIO.

Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term. The BIO recently held a convention which included seddions to coach lawyers on the shifting landscape for patents. Each meeting was packed.

It can be learned from Paragraph I that the biotech companies would like()

A. their executives to be active

B. judges to rule out gene patenting

C. genes to be patentable

D. the BIO to issue a warning
