(2020·合肥第一次質檢)We can have video chat with astronauts aboard the International Space Station and watch live footage from the frozen heights of a mountain. But communicating with a submarine(潛艇) or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne(空氣傳播的) devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar signals used by underwater sensors reflect off the surface of water rather than reaching the air.
Now, researchers at MIT have developed a method with the potential to revolutionize underwater communication. “What we’ve shown is that it’s actually feasible to communicate from underwater to the air，” says Fadel Adib, a professor at MIT’s Media Lab, who led the research.
The MIT researchers designed a system that uses an underwater machine to send sonar signals to the surface, making vibrations(震動) corresponding to the 1s and 0s of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. “It has any number of potential real-world uses，” Adib says. “It could be used to find downed planes underwater by reading signals from sonar devices in a plane’s black box and it could allow submarines to communicate with the surface.”
Right now the technology is low-resolution. The initial study was conducted in the MIT swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms, schools of fish. They also want to see if they can make the technology work in the other direction—air to water. If the technology proves successful in real-world conditions, expect “texting while diving” to be the latest underwater fashion.
【解題導語】　本文是一篇說明文，主要介紹了一項麻省理工學院的科學家發(fā)明的從水下與地面上的人進行通信的技術。
5．What does the author mainly talk about in Paragraph 1?
A．The future of video chat underwater and in air.
B．The frustrations of developing underwater devices.
C．The difficulty of communication from water to air.
D．The current situation of communicating with a submarine.
C　解析：段落大意題。通讀第一段的內容可知，該段主要講的是從水下與地面的人進行通信非常困難，故選C。
6．What does the underlined word “feasible” mean?
A．Achievable. B．Convenient.
C．Changeable. D．Alternative.
A　解析：詞義猜測題。根據(jù)第二段第一句“Now, researchers at MIT have developed...underwater communication.”可知，麻省理工學院的研究人員發(fā)明了一種可能改變水下通信的方法，使從水下與地面上的人進行溝通成為可能，故A項“可實現(xiàn)的”與畫線詞意思最相近。故選A。
7．What do we know about TARF?
A．It is widely used to find downed planes.
B．It can work well at great depths underwater.
C．It is an underwater machine that sends signals.
D．It can send, receive and read signals from underwater.
D　解析：推理判斷題。文章第三段詳細講述了TARF系統(tǒng)的工作原理：該系統(tǒng)使用一個水下機器向水面發(fā)送聲吶信號，對0到1秒的數(shù)據(jù)產(chǎn)生震動，然后水面接收器讀取并對這些微小的震動進行重新編碼，這樣可以從水下與地面上的人進行通信。故選D。
8．What is the best title for the text?
A．The Real-world Uses of Sonar Technology
B．Full Water-to-air Communication Closer to Reality
C．A Breakthrough in the Application of Video Chat
D．TARF Becoming a New Means of Communication
B　解析：標題歸納題。通讀全文可知，本文主要介紹了科學家發(fā)明的一種從水下與地面上的人進行通信聯(lián)系的系統(tǒng)，研究人員將會把它投入到真實的狀況下進行驗證，因此B項最適合作本文標題。
