问题 Citizen Scientists
Understanding how nature responds to climate change will require monitoring key life cycle event -- flowering, the appearance of leaves, the first frog calls of the spring -- 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- 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. 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 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 every year. The program, called Project Bud Burst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone -- record their observations on the Project Bud Burst website.
"People don't have to be plant experts -- 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 ofh0w plants and communities of plants and animals will respond as the climate changes."
Ecologists turn to non-scientist citizens for help because they need them（）
选项 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.
答案C
解析细节题。题干：生态学家向非科学家的市民寻求帮助是因为他们需要他们____。利用题干关键词turn to non—scientist citizens for help可以定位到第一段，“了解自然如何对气候变化作出反应，需要检测重要的生命循环事件，但是生态学家们不可能观察每一个地方的气候变化的现象，所以就向普通人需求帮助”，由此可知C项“收集生物生命周期的数据”是正确答案。
