Scientists have discovered a powerful antibiotic in the blood stream of giant pandas that can destroy bacteria. The Chinese researchers discovered the【C1】________known as cathelicidin-AM, after【C2】________the panda’s DNA It’s thought that the antibiotic is【C3】________by the bear’s immune system in order to protect them from infections.
The scientists found that cathelicidin-AM killed bacteria in less than an hour【C4】________other antibiotics took more than six hours. They now want to develop the substance as a new drug to fight superbugs.
The【C5】________bears, of which there are just 1,600 in the wild, have become a symbol for conservation—and now there could be a new reason to try and protect them.【C6】________, scientists will not need to rely on the animal’s unreliable breeding ability to【C7】________the new antibiotic, as they have been able to make it artificially in the lab by decoding the genes to produce a small molecule known as a peptide.
Dr Xiuwen Yan, who led the research at the Life Sciences College of Nanjing Agricultural University in China told the Daily Telegraph: "It showed potential antimicrobial activities against wide【C8】________of microorganisms including bacteria, both standard and drug-resistant【C9】________. Under the pressure of increasing microorganisms【C10】________drug resistance against conventional antibiotics, there is【C11】________need to develop new type of antimicrobial agents. Gene-encoded antibiotics play an important role in immune system against【C12】________microorganisms. They cause much less drug resistance than conventional antibiotics."

It has been【C19】________that the millions of pounds spent in using expensive artificial breeding techniques could be put to better use on other conservation projects. And this new discovery is likely to【C20】________the case to save the endangered creatures.
【C2】
选项
A、analyzing
B、observing
C、exploiting
D、taking
答案
A
解析
本句说的是中国的科研人员如何发现这种强力抗生素的。只有通过分析等研究手段才能有此发现,故选A项analyzing“分析”。B项observing表示“观察”,通过观察无法弄清楚DNA内在的成分。C项exploiting表示“开采,利用”,利用DNA也无从发现其中的成分。D项taking“表示“获得”,得到熊猫的DNA而不加以分析,也无法有此发现。
