第二部分 阅读理解（共20小题；每小题2.5分，满分50分）
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。
A
So you want to be a civilian scientist? The National Science Foundation(NSF)has got you covered. NSF supports civilian science across all area of science, whether your passion is to scan the night sky, or explore your own backyard.
Join a group of birders.
eBird is an online platform that allows bird-watchers to go online and record their sightings to a database.With more than 100,000 active users, eBird’s system is a treasure of information on bird
population, distribution and habitat, with users can explore in real time.
Count every drop.
The Community Collaborative Rain. Hall and Snow Network(CoCoRaHS) is the largest provider of daily precipitation(降水)observations in the United States.Volunteers set up rain gauges(测量仪器)and record data every time rain or snow passes over. Data is organized and shared on the CoCoRaHS website, and used by scientists, farmers and more.
Search for stars with your computer.
Einstein@Home uses your computer’s spare time to search for space signals. The project has already had major successes; Volunteer discovered about 50 stars, using data from Puerto Rico’s Arecibo Observatory and Australia’s Parkess Observatory. Einstein@Home also searches for gravitational-wave signals using data from NSF’s Laser Interferometer Gravitational Wave Observatory.
Be part of a supercomputer.
To link all those home computers, Einstein@Home uses the software called the Berkeley Open Infrastructure for Network Computing, better known as BOINC. The software choreographs(编排)the technical aspect of volunteer computing and help you use radio telescope signals to search for creatures outside the earth.
Join the Plankton Party.
Without plankton, life in the ocean would not exist. These tiny organisms form the base of the food chain, and play an important role in the global carbon cycle. Plankton Portal enlists(征募) civilian scientists to identify images of plankton, snapped by In Situ Icthyoplankton Imagine System(ISIIS),an underwater robot engineered at the University of Miami. ISIIS has taken millions of images in oceans around the world; classifying the images helps researchers understand plankton diversity, habitat and
behavior.

The Common Application for college, known as the Common App, is a timesaving tool accepted by more and more schools each years—public, private, large, and small. Depending on where you plan to apply, you may be able to save yourself from writer’s cramp(痉挛)because you only have to complete it once, filling out the typical pages of information just a single time. After that ,you can send it out over and
B.Become a Citizen Scientist! D.Make a Contribution to NSF!
over again in clear photocopy form. Better yet, it can be completed online at www.commonapp.org.
Member schools of the Common Application organization are allowed membership only if they stick to a whole applicant evaluation process. If you’re checking the sites of your favorite colleges and they’re members of the organization, then there’s a good chance they’ll have a link right on their site that will take you straight to the college Common Application at its home website. As an added bonus, several dozens of these schools will reduce or give up their application charge if you apply online.
It’s not unusual for some colleges to require a brief supplement(补充)unique to their school in addition to the Common Application. Many of those supplements require applicants to write an extra essay or two, so if you plan to use the Common Application, make sure you’re submitting everything that the school is requesting.
There’re rumors(谣言)that some schools don’t treat the Common Application with the same regard as their own unique applications. Thankfully,such rumors appear to be mostly just that—rumors.Colleges accepting the Common Application promise to give it equal weight, and they do. In fact, more and more schools now only use the Common Application.
For a list of participating schools and to access the college Common Application online, visit www.commonapp.org. Peterson’s is your guide to college information. Use Peterson’s college search to find the best college or university for you.
