共用题干 第二篇Citizen ScientistsUnderstanding 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 specificresearch 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." Ecologists turn to non-scientist citizens for help because they need them________________.
A.to provide their personal life cycles B.to observe the life cycle of plants C.to collect data of the life cycle of living things D.to teach children knowledge about climate change正确答案C
