请根据短文内容，回答题。 Citizen Scientists Understanding how nature responds to climate change will require monitoring key life cycle events- flowering, the appearance of leaves, the first frog calls of the spring--all around the world. But ecologists can&39;t be __________(51) so they&39;re turning to non-scientists, sometimes called citizen scientists, for help. Climate scientists are not present everywhere. __________ (52) there are so many places in the world and not enough scientists to observe all of them, they&39;re asking your help in __________ (53)signs of climate change across the world. The citizen scientist movement encourages __________ (54)people to observe a very specific research interest--birds, trees, flowers budding, etc.- and send their observations__________ (55) a giant database to be observed by professional scientists. This helps a small number of scientists track a__________ (56) amount of data that they would never be able to gather on their own. __________(57) like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready for the condition- where they live. __________ . (58) that&39;s needed to become one is a few minutes each day or each week to gather data and __________(59)it in. A group of scientists and educators launched an organization last year __________(60) the National Phenology (生物气候学) Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group&39;s first efforts relies on scientists and non-scientists__________ (61) to collect data about plant flowering and leafing every year. The program, called Project Bud Burst, collects cycle __________ (62) on a variety of common plants from across the United States. People participating in the project--which is__________ (63) to everyone--record their observations on the Project Bud Burst website. "People don&39;t__________ (64) to be plant experts- they just have to look around and see what&39;s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we&39;ll be able to make an estimate of__________(65) plants and communities of plants and animals will respond as the climate changes." _________ 查看材料
