Citizen Scientists

Understanding how nature responds to climate change will require monitoring key life cycle events一
flowering,the appearance of leaves,the first frog calls of the spring一all around the world.But ecologists
（生态学家）can' t be everywhere so they' re turning to non-scientists, sometimes called citizen scientists,
for help.
Climate scientists are not present everywhere.Because there are so many places in the world and not
enough scientists to observe all of them,they're asking for your help in observing signs of c1imat。 ehang,
across the world.The citizen scientist movement encourages ordinary people to observe "very specific
research interest一birds,trees,flowers budding,etc. and send their observations to a giant database
（数据库）to be observed by professional scientists. This helps a small number of scientists track a large
amount of data that they would never be able to gather on their own.Much like citizen journalists helping
large publications cover a hyper-local beat,citizen scientists are ready for the conditions where they live.All
that's needed to become one is a few minutes each day or each week to gather data and send it in.
A group of scientists and educators launched an organization last year called the National Phonology
Network."Phenology"is what scientists eni1 the study of the timing of events in nature.
One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant
flowering and leafing every year. The program,called Project BudBurst,collects life eyele data on a variety
of common plants from across the United States.People participating in the project一which is open to every-
one一record their observations on the Project BudBurst website.
"People don't have to be plant experts一they just have to look around and see what's in their
neighborhood,"says Jennifer Schwartz,an education consultant with the project."As we collect this data,
we'll be able to make an estimate of how p'ants and communities（生物群落）of plants and animals will re-
spond as the climate changes."
选项 Ecologists turn to non-scientist citizens for help because they need them________________.A:to provide their personal life cyclesB:to observe the life cycle of plantsC:to collect data of the life cycle of living thingsD:to teach children knowledge about climate change
答案C
解析由第二段可知，科学家是在请普通公民观察气候变化的某些迹象并将数据传到指定网址上，故选Co 由第二段第三句“…encourages ordinary people to observe a very spccific research interesl—…send their observations to a giant database to be observed by professional scientists."可知应选B。 仔细看该词所在句的前一句“Much like citizen journalists.., citizen scientists are ready for...”可知，one指one of citizen scientists。所以正确答案为B。 文章倒数第二段提到“People participating in the project一which ie open to everyone"，山 此可知这个计划向所有人开放，因此A为本题答案。 文章第一句“Understanding how nature responds to climate change"和文章最后一句“…to make an estimatc of how planu and communities of plants and animals will respond as the climate changes.”都给出了研究的目的，所以D为正确答案。第三篇 本文主要介绍了撒哈扛沙漠的地理位置、气候权况、农业和交通运输状况
