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."

选项
A、urgent
B、basic
C、rush
D、hasty
答案
A
解析
前面提到under the pressure of(在……压力下),后面说需要研发新型抗菌剂,有压力,可以推断出这种需要是紧迫的。A项urgent“紧迫的”语义符合。B项basic表示“基本的”,不能表明在压力下这种需要的紧迫性。而C项rush“急需的”及D项hasty“匆忙的,草率的”与need无法搭配。
