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.
【C2】
选项
A、emerged
B、rose
C、intruded
D、originated
答案
A
解析
空格词所在句与上文两句并列,前两句都提及在某一年度出现或发现了某种冠状病毒。由此可知,该空所填词应与came和identified意思相近,表示病毒“出现”,所以A项emerged(出现)符合题意。B项rose表示“增加;上升”,C项intruded表示“侵入;打扰”,D项originated表示“起源;发源”,三项均不符合句意,故排除。
