10．President Barack Obama told ABC news _______ he was aware of the development of the recent investigation．
A．thatB．whatC．whichD．whether

分析 美國總統(tǒng)巴拉克•奧巴馬跟美國廣播公司說他知道最近調(diào)查事件的進展．

解答 答案：A．
本句中told后面有兩個賓語，賓語從句he was aware of the development of the recent investigation中不缺少成分，所以應該用that來引導，故選A．which表示范圍，而what在賓語從句中是充當成分的，whether表示疑問"是否"．be aware of意識到，知道．

點評 注意了解賓語從句的引導詞，區(qū)分不同連接詞的用法以及在句中是否擔當一定的成分，結(jié)合句意作出合理的判斷．

So you want to be a citizen scientist? The National Science Foundation (NSF) has got you covered. NSF supports citizen science across all areas of science, whether your passion is to scan the night sky, or explore your own backyard.

Join a flock 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, which users can explore in real time.

Count every drop

The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) is the largest provider of daily precipitation observations in the United States. Volunteers set up rain gauges and record data every time a rain, snow or hail storm 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 idle time to search for space signals. The project has already had major successes: Volunteers discovered about 50 stars, using data from Puerto Rico's Arecibo Observatory and Australia's Parkes 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, Einstien@Home uses software called the Berkeley Open Infrastructure for Network Computing, better known as BOINC. The software choreographs(安排，籌劃) the technical aspect of volunteer computing and helps you use radio telescope signals to search for alien life.

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 citizen scientists to identify images of plankton, snapped by the In Situ Icthyoplankton Imaging System (ISIIS), an underwater robot engineered at the University of Miami. ISIIS has taken millions of images in oceans around the world and upload them into a database; classifying the images helps researchers understand plankton diversity, habitat and behavior.

1.On the website of eBird, a bird-watcher can ________.

A. make contact with other active users

B. explore the world of birds in real time

C. observe all the existing bird species

D. provide and share birds’ information

B

STAY INFORMED WITH CITIZENS,BANK!

Are you a busy person who likes to stay on top of your finances? Then why do you waste your time constantly checking your bank account? Citizens' Bank now offers a new service for you.

With our new Automated Alert Service,Citizens' Bank account holders can have important account information sent directly to their cell phone or email address.The type of information you'll receive is up to you;

●Be informed when your account balance drops below a certain level.

●Receive notification (通知）when a specific check clears.

●Find out instantly whenever a withdrawal is made.

And at the end of the month,your complete bank statement will still be sent to you.With Automated Alerts,staying on top of your banking will be a lot easier.For more information,contact us at aas@citizensbank.net or drop by your nearest branch.

From;Robert Renfield robertyaho@nemo.com

To:Citizens' Bank aas@citizensbank.net

Subject;An Inquiry of the Alert Service

Good afternoon,

I am writing to request more information on your new Automated Alert Service,as advertised on your Website.I have had both personal and commercial accounts with Citizens' Bank for many years.Often,I find it necessary to move money between accounts.Because of this,it is vital that I keep a close eye on the cash flow of all of my accounts,to assure that their balances stay above the required minimums.Therefore,I have been searching for an economical means of keeping better track of my finances.I was considering purchasing software for this purpose,but I think that your new service might be a convenient alternative.

My first question concerns the timeliness of the notifications.When you say “instantly,” does that relate only to banking hours? For example,if my wife were to use our debit card (借記卡）on a Sunday afternoon to make a transfer (轉(zhuǎn)賬）at an ATM,would I be informed via email instantly or on Monday morning? My second question is in regard to the information available in this service.Is it possible to be aware of any information in my monthly bank statement,such as interest on my savings account? Finally,I would like to know the cost of this service.

Please send me this information as soon as possible.If necessary,you can contact me in the evenings at 225-782-0902.
