Ⅰ. 阅读理解 We can vide chat with astrnauts abard the Internatinal Space Statin and watch live ftage(直播) frm the frzen heights f Everest. But cmmunicating with a submarine(潜艇) r a diver is nt s easy. The lack f practical methds fr sharing data between underwater and airbrne devices has lng been a frustratin fr scientists. The difficulty riginates frm the fact that radi signals wrk perfectly in air travel but prly in water. Snar(声呐) signals used by underwater sensrs reflect ff the surface f the water rather than reaching the air.
Nw, researchers at MIT have develped a methd with the ptential t revlutinize underwater cmmunicatin. “What we’ve shwn is that it’s actually feasible t cmmunicate frm underwater t the air, ” says Fadel Adib, a prfessr at MIT’s Media Lab, wh led the research.
The MIT researchers designed a system that uses an underwater machine t send snar signals t the surface, making vibratins(震动) crrespnding t the 1s and 0s f the data. A surface receiver then reads and decdes these tiny vibratins. The researchers call the system TARF. “It has a number f ptential real-wrld uses, ” Adib says. It culd be used t find dwned planes underwater by reading signals frm snar devices in a plane’s black bx and it culd allw submarines t cmmunicate with the surface.
Right nw the technlgy is lw-reslutin. The initial study was cnducted in the MIT swimming pl at maximum depths f arund 11 r 12 feet. The next steps fr the researchers are t see if TARF is wrkable at much greater depths and under varying cnditins—high waves, strms, schls f fish. They als want t see if they can make the technlgy wrk in the ther directin—air t water. If the technlgy prves successful in real-wrld cnditins, expect“texting while diving” t be the latest underwater fashin. 【文章大意】这是一篇说明文, 讲述的是水下与陆地上的通信在之前是无法实现的。随着科技的进步, 这一通讯逐渐能够变为现实。
1. What des the authr mainly talk abut in Paragraph 1? A. The future f vide chat underwater and in air. B. The difficulty f cmmunicatin frm water t air. C. The frustratins f develping underwater devices. D. The current situatin f cmmunicating with a submarine. 【解析】选B。细节理解题。根据第一段的第二、三句“But cmmunicating with a submarine r a diver is nt s easy. The lack f practical methds fr sharing data between underwater and airbrne devices has lng been a frustratin fr scientists. ”可知, 从水里向空气中传递信息, 进行交流是很困难的。
2. What des the underlined wrd “feasible” mean? A. Changeable. 　　B. Cnvenient. C. Achievable. D. Alternative. 【解析】选C。词义猜测题。根据第二段的第一句“Nw, researchers at MIT have develped a methd with the ptential t revlutinize underwater cmmunicatin. ”可推断海底与外界的沟通实际上是可行的。所以该词的意思是“可行的, 可实现的”。
3. What d we knw abut TARF? A. It is widely used t find dwned planes. B. It can wrk well at great depths underwater. C. It is an underwater machine that sends signals. D. It can send, receive and read signals frm underwater. 【解析】选D。细节理解题。根据第三段前三句内容可知, TARF系统可以从水下发送、接收和读取信号。
4. Which f the fllwing is the best title fr the passage? A. The Real-wrld Uses f Snar TechnlgyB. A Breakthrugh in the Applicatin f Vide ChatC. Full Water-t-air Cmmunicatin Clser t RealityD. TARF Becming a New Means f Cmmunicatin【解析】选C。标题归纳题。根据第一段的最后两句和第二段的第一句可知, 本文讲述的是水下与陆地上的通信在以前是无法实现的, 但随着科技的进步, 这一通讯逐渐能够变为现实。
