In the past 20 years alone, three coronaviruses have caused major disease outbreaks. First came the original SARS virus in 2002.【C1】________. in 2012, MERS was identified. In 2019, SARS-CoV-2【C2】________.
Hundreds of other coronaviruses are known to be【C3】________in bats and other animals. Scientists have warned that some of them could arise in the future and【C4】________infect people. Our current COVID-19 vaccines were specifically【C5】________for SARS-CoV-2, but what if a next-generation vaccine could protect【C6】________both known and unknown coronaviruses?
Scientists at the Walter Reed Army Institute of Research are working on a so-called universal coronavirus vaccine. Dr. Kayvon Modjarrad is【C7】________the effort. They have developed a vaccine specifically for SARS-CoV-2, and found that the immune response that it【C8】________is active against all the variants, as well as other coronaviruses like SARS-CoV-1. And this gives them confidence that it can be a platform for the entire coronavirus family.
The vaccine is known as SpFN, which combines nanoparticles from ferritins with coronavirus spike proteins. But making the vaccine wasn’t as【C9】________as attaching one protein to another. Modjarrad and his colleagues had to【C10】________which parts of the spike to attach to which type of ferritin and how to【C11】________the two proteins together. It took months of trying more than 200 different【C12】________. By June of last year, the team found one version that succeeded where others had failed. They then【C13】________the experimental vaccine in mice and monkeys.
The team also turned to less【C14】________animals for testing. Working with scientists in India, they【C15】________horses with the vaccine to learn how strong the【C16】________response was. And they【C17】________with Helen Dooley at the University of Maryland to vaccinate sharks—which make special antibodies.
The results are【C18】________. but animals aren’t people. The Army vaccine is now being tested in a small, early-stage trial in humans.【C19】________it works and is safe, it could lay the【C20】________for a universal coronavirus vaccine.
【C14】
选项
A、conventional
B、familiar
C、odd
D、rare
答案
A
解析
空格所在部分为第五段首句:The team also turned to less________animals for testing (该团队还使用了不________的动物进行试验),空格处需要填入一个形容词,对animals进行限定。由上文可知,研究团队已对mice和monkeys进行了疫苗试验,现在又要对其他动物进行试验,后文提到被实验的动物是horses和sharks。相对于老鼠和猴子这些实验室中常用的实验动物而言,马和鲨鱼很少被用作实验动物,故空格词的意思应与“常见的;常规的,传统的;通常的”相关,选项中满足此要求的只有A项conventional“传统的,常规的”,故为答案。B项“熟悉的”,C项“奇异的”,D项“稀有的”,代入原文,均不符合上下文语境,故排除。
