Question

You never see him, but they’re with you every time you fly. They record where you are going, how fast you’re traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They’re known as the black box.
　When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潛水艇) detected the device’s homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
　In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架艙). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
　Modern airplanes have two black boxes: a voice recorder, which tracks pilots’ conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft’s final moments. Placed in an insulated (隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand（抵擋）massive force and temperatures up to 2,000℉. When submerged（潛入水中）, they’re also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they’re still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane’s black boxes were never recovered

Answer 1

CACA
試題分析：
1.C細(xì)節(jié)題。由Their ability to withstand almost any disaster makes them seem like something out of a comic book. They’re known as the black box.可知其抵御災(zāi)害的能力是令人難以置信的，故選C
2.A 由第二段第1,2行When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong.可知，這個(gè)黑匣子里面有很多的數(shù)據(jù)可供分析使用，故A正確。
3.C倒數(shù)第二段Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned…文中提到，早期的黑匣子經(jīng)�？共蛔】针y的破壞(failed to withstand crashes)，因此在1965年，黑匣子重新設(shè)計(jì)(redesigned)，所以答案為C。
4.A最后一段Experts believe the boxes from Air France Flight 447, which crashed near Brazilon June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.文中提到，專家相信法航447號(hào)的黑匣子是在水下20000英尺的深度，接著指出，但是統(tǒng)計(jì)數(shù)據(jù)顯示他們?nèi)匀豢赡艹霈F(xiàn)，即有可能被找到，接下來的具體統(tǒng)計(jì)數(shù)據(jù)也進(jìn)一步說明了這一點(diǎn)，所以答案為A。
考點(diǎn)：考查科普類短文閱讀
點(diǎn)評(píng)：本文主要講了“黑匣子”的一些相關(guān)事宜。對(duì)于推理題的考查較多，在解答這類問題時(shí)要求學(xué)生抓住題干文字信息，采用針對(duì)性方法進(jìn)行閱讀，根據(jù)詞義關(guān)系推斷具體細(xì)節(jié)，結(jié)合上下文提供的語境和信息進(jìn)行概括和判斷。
