According to Schwartz, what can help people know more about climate change ？（）
A．Taking a course on phenology.
B．Knowledge of life cycle s of plants and animals.
C．Efforts of ecologists to learn more about plant flowering.
D．Full support of citizen scientists to study climate changes.
A.
Understanding how nature reacts to climate (气候) change will require checking key life cycle s--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.
B.
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 s in nature.
C.
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.
D.
"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. "
E.
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.
F.
"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. \

【单选题】有些被宣称为“清热下火”的凉茶，其实连茶的远亲都算不上，它们不是普通的“茶叶”，只是含些中草药提取液。从现代医学角度看，人体的许多症状跟中医所说的“热”，“火”类似，而这些症状，有许多是会自然减退的，不管喝凉茶还是白水，一段时间后都会减轻。另一方面，在理论上完全可能有中草药的某些成分正好对某些症状有效，所以不少人喝了凉茶，觉得清了“热”，下了“火”，这并不奇怪。但是，这样一种“有效”却符合大众的思...
