Passage 2

Questions 6 to 10 are based on the following passage.

When asked about the possibility of futurepandemics, scientists say another one is coming and it's just a matter of when.

In fact, there are about 1.7 million viruses(病毒) that are believed to exist in animals, and nearly half could potentially jump from animals to humans andkick off another pandemic. Finding ways to prevent that is the motivation driving a team of researchers at the University of California at Davis. They are trying to help the world’s scientists determine how dangerous each virus might be by ranking its likelihood of being transmitted(传染)to humans and changing into a form that humans could easily pass to one another.

The team has launched a web-based tool called Spillover. It evaluates 32 risk factors to generate a risk score.“We looked at viruses known to be transmissible from animals to humans and those that were newly discovered,”says Zoe Grange,who worked on the project as a wildlife disease scientist. By marking“high-risk”viruses, this publicly available database is intended to create a watchlist (观察名单) for scientistsand policymakers.

(78)Grange and her colleagues came up with the idea of a ranking tool in the spring of 2017.The Spillover database is designed so that researchers can add their own reports. They can add their virus discoveries and do their own rankings. (79) It’s a tool everyone can use.Unlike other tools that evaluate the risk of a limited number of viruses, this database focuses on 887 viruses found in wildlife. SARS-CoV-2, which is the virus behind COVID-19, comes in second place for its likelihood to cause disease and spread within human populations.

当被问及未来流感大流行的可能性时，科学家们表示，另一场大流行即将到来，只是时间问题。

事实上,大约有170万个病毒(病毒),被认为存在于动物,和将近一半可能从动物传给人类andkick另一大流行。加州大学戴维斯分校(University of California at Davis)的一组研究人员的动力就是找到预防这种情况的方法。他们正试图帮助世界上的科学家们确定危险每个病毒可能通过排名被传播的可能性(传染)对人类和人类改变成一种很容易通过。

该团队推出了一款名为“溢出”(Spillover)的网络工具。它评估32个危险因素来生成一个风险评分。“我们研究了已知的从动物传染给人类的病毒，以及那些新发现的病毒，”参与该项目的野生动物疾病科学家佐伊·格兰奇(Zoe Grange)说。标记“高风险”病毒,这个公开数据库旨在创建一个观察名单中(观察名单)的科学家和政策制定者。

(78)Grange和她的同事在2017年春天提出了排名工具的想法。Spillover数据库的设计使研究人员可以添加自己的报告。他们可以添加自己发现的病毒，并进行自己的排名。这是一个人人都能使用的工具。与其他评估有限数量病毒风险的工具不同，该数据库侧重于在野生动物中发现的887种病毒。COVID-19背后的病毒SARS-CoV-2在引发疾病和在人群中传播的可能性方面排名第二。
