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."
Panda populations have decreased【C13】________the destruction of their natural habitat and bamboo food【C14】________ in China and south east Asia.【C15】________to increase then-numbers, including efforts at Edinburgh Zoo with resident pandas Tian Tian and Yang Guang, have been【C16】________for the extreme difficulty in getting them to breed in captivity.【C17】________in the wild, pandas【C18】________to breed easily, as the females only come into season once a year.
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.
【C18】
选项
A、tend
B、seem
C、like
D、struggle
答案
D
解析
前面提到熊猫的繁殖不容易,而空格后却说容易繁殖(to breed easily),可见应填的词需否定后面的内容。D项struggle“挣扎”能够体现出繁殖的不易。A项tend“倾向于”。大熊猫倾向于容易繁殖,语义逻辑不符合。B项seem“似乎”,也没有体现出繁殖的困难。C项like“喜欢”,大熊猫喜不喜欢繁殖在文中未涉及。
