Why are citizen scientists invited to take part in Project BudBurst ？（）
A．To give a hand in research.
B．To teach science to the public.
C．To help create a website of popular science.
D．To call people’s attention to climate change.
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】What is the disadvantage of studying a language online ？（） A．You may not be able to keep up with the program. B．You may not meet your teachers in person. C．The computer may break down any time. D．The ...
A.
Looking to improve your language skills, but you don’t have the time to go abroad to attend school More and more universities around the world are offering opportunities for students to get degrees online ( distance education) from the comfort of their own homes, and many of these colleges and universities are accredited (官方认可的), meaning that they have met certain standards of excellence.
B.
If you decide to take language courses online (or any subject for that matter), be sure there are advantages in studying online. Its costs are usually lower, and you can study at your own pace (节奏) and you can easily get the materials 24 hours a day from almost any computer in the world. However, you won’t get the human interaction (互动) of meeting people face to face, as you would if you were attending a school abroad in person.
C.
On the other band, the advantages of going abroad may include day-to-day chances to learn a new culture, to meet new friends with whom you can use and practice the language, and to see different parts of the world. However, there may be a number of disadvantages for some students, including high costs, time away from one’s school, family, or work life, and difficulty in getting used to anew culture and way of life.
D.
Whatever you do, consider a distance education program that meets your educational needs, is what you can afford, and equally important, provides you with chances to grow beyond the classroom through cultural and educational activities.
