Understanding how nature reacts to climate (气候) change will require checking key life cycle events--flowering, the appearance of leaves, the first frog calls of the spring--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.
A group of scientists and educators set up 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 is to ask scientists and non-scientists to collect information about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle information on a variety of common plants from across the United States. People taking part in the project record their information on the Project BudBurst website.
"People don’t have to be scientists--they just have to look around and see what’s in their neighbourhood," says Jennifer Schwartz, a scientist with the project. "As we collect this information, we’ll be able to know about the changes of plants and animals as the climate changes. "
Not only that, the information also helps scientists learn about how these changes will have an effect on people, Scientists examining lilac (丁香花) flowering in western United States reported that in years when lilacs flowered early--before May 20th-wildfires later in the summer and fall were likely to be larger and more serious. Lilac flowering, then, could serve as an alarm bell.
"The best way for us to increase our knowledge of how plants and animals are reacting to climate change is to increase the count of information we have," Schwartz says. "That’s why we need citizen scientists to get as much information from as many places on as many plants and anireals over as long a time period as we can. "
The author uses lilac flowering as an example to show ______.
选项
A、flowers could help prevent wildfires
B、plant flowering can be related to wildfires
C、some flowers are closer to our life than others
D、lilacs are the best plants to show climate change
答案
B
解析
细节题。题干意为“作者用丁香花花开作为例子来说明一______。”根据第五段第二句“Scientists…when lilacs flowered early--before May 20th--wildfires later in the summer and fall were likely to be larger and more serious.”可知,植物开花时间和森林火灾有关系。故B为正确答案。
