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.

选项
A、Unfortunately
B、Thankfully
C、Surprisingly
D、Naturally
答案
B
解析
上句提到生存在野外的大熊猫数量仅有1,600只左右,说明非常的稀有,空格后又说科学家们不需要依赖熊猫不稳定的繁殖能力,这对于科学家来说是一件幸运的事。B项Thankfully意为“幸运地是”,符合逻辑。A项Unfortunately“不幸地是”,与空格后所说的内容不一致。B项Surprisingly“使人惊奇地”。下文提到科学家可以人工合成这种抗生素,因此科学家们不需要依赖熊猫不稳定的繁殖能力并不令人惊奇。D项Naturally“自然而然地”,句子的主句和从句不是顺承关系,不符合语义逻辑。
