Citizen Scientists

Understanding how nature responds to climate change will require monitoring key life cycle events一
flowering,the appearance of leaves and the first frog calls of the spring一all around the world.But ecologists
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 climate change
across the world.The citizen scientist movement encourages ordinary people to observe a very specific

research interest一birds,trees,flowers budding,etc.and send their observations to a giant database 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 in.All that's needed to become
one is a few minutes each day or each week to gather data and send them in.
A group of scientists and educators launched an organization last year called the National Phenology
Network."Phenology"is what scientists call 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 eveiy year.The program,called Project BudBurst,collects life cycle 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 neighbor-
hood,"says Jennifer Schwartz,an education consultant with the project."As we collect these data,we'll be
able to make an estimate of how plants and communities of plants and animals will respond as the climate
changes."

选项 What is the final purpose of Project BudBurst? A:To study when plants will have their first buds. B:To find out the types of plants in the neighborhood. C:To collect life cycle data on a variety of common plants from across the United States. D:To investigate how plants and animals will respond as the climate changes.

答案 D

解析
短文第一段提到科学家们不可能观察每一个地方的气候变化的现象，所以邀请普通人为他们观察、收集信息。
短文第二段讲到，平民科学家运动鼓励普通人根据自己的兴趣来观察某一个特定的方面，并把他们的观察结果发送到一个巨大的数据库来供专业科学家研究。结合选项，可知答案为B。
短文第二段最后一句话的后半部分“所要做的仅仅是每天或每周抽出几分钟的时间来收集数据并发送到数据库”可知，"one”是针对citizen scientist来说的。
全文都在讲述普通人参与科学项目的研究，只有A选项不符合题意。其他选项都能在文中找到。
短文最后一段指出，通过收集数据，我们就能够估算出气候变化对植物和生物群落会有怎样的影响。所以选D。第5部分：补全短文
