Kevin Davies sent a sample of his saliva to a genetic testing laboratory in Iceland to learn about his health risks. When he received his results, Mr. Davies learned that,【C1】______his genetic makeup, he had an above-average risk of【C2】______prostate cancer. Out of【C3】______, he checked back three months later and found that the company, called deCODE, had changed its assessment; His risk was now【C4】______average.
DeCODE had recalculated its algorithm, based on new data. Davies, who is himself a geneticist by training, wasn’t too【C5】______by this about-face: " The information that these companies can give you can change and evolve【C6】______time," he says.
That isn’t the only way today’s genetic tests offer【C7】______conclusions. According to a US government study, results often vary【C8】______among genetic-testing companies, largely because【C9】______has its own way of choosing and analyzing data.
When the project to【C10】______human DNA was finally completed in 2003, many predicted a revolution. Drugs could be chosen to match individual patients with maximum therapeutic effect and minimum side effects, the【C11】______of so-called personalized medicine.
【C12】______a summer downpour of troubling stumbles for genetic-testing companies and programs shows just how long and twisting the road can be【C13】______advances in basic scientific research and their application.
It also has【C14】______the question of how medicine will be practiced in an era【C15】______anyone can research ailments and treatments on the Internet, sometimes becoming more familiar with new therapies and tests than their physicians.
【C7】
选项
A、slippery
B、positive
C、complicated
D、convincing
答案
A
解析
本句考查形容词的词义辨析和对文章上下文的理解。A不可靠的;B正面的;C复杂的;D令人信服的。由前文我们可以了解到,基因测试的结果会随着时间而发展变化,也就是不可靠。本句的大意是,当前基因测试的结果不可靠是比较常见的情况,并不仅仅体现在Kevin Davies的这两次基因测试报告的结果不同。
