真題再現(xiàn)

例1：

In the past few years, prominent schools around the world have joined the trend. In?2003, whenCambridge University?appointed?Alison Richard, another former Yale provost, as its vice-chancellor,the university publicly stressed that in her previous job she had?overseen（監(jiān)督）?“a major strengthening of Yale’s financial position.”(2009.12,cet4)

65. Cambridge University appointed Alison Richard as its vice-chancellor chiefly because _____.

A. she was known to be good at raising money

B. she could help strengthen its ties with Yale

C. she knew how to attract students overseas

D. she had boosted Yale’s academic status

【答案】A

【解析】

文中提到，劍橋大學(xué)于2003年任命Alison Richard為副校長，而句中publicly stressed（公開強(qiáng)調(diào)）之后的內(nèi)容即為任命她的原因，便是：在以前的崗位上她的監(jiān)管使得“耶魯?shù)呢?cái)政地位得到顯著加強(qiáng)”。所以，推理可知，答案為A。

例2：

Richard Got?professor of astrophysics at?Princeton, hopes man will set up a self-sufficient colony onMars,?which would be a “l(fā)ife insurance policy against whatever catastrophes, natural or otherwise, might occur on Earth. (2008.6,cet6)

6. According to Princeton professor Richard Gott, by setting up a self-sufficient colony on Mars, Humans_____.?
A. might survive all catastrophes on earth

B. might acquire ample natural resources?
C. will be able to travel to Mars freely

D. will move there to live a better life

【答案】A

【解析】

題干中setting up a self-sufficient colony on Mars可在原文中直接找到，原文中which引導(dǎo)的定語從句表示的內(nèi)容就是setting up a self-sufficient colony on Mars所帶來的影響：人類能夠應(yīng)對(duì)地球上各種各樣的災(zāi)難從而幸存下來。A選項(xiàng)中的survive all catastrophes on earth 是對(duì)原文的同義轉(zhuǎn)述。

動(dòng)手練一練！

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 toComorosIslandsin theIndiaocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a Frenchsubmarine?(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 massive force and temperatures up to2,000℉. When submerged, they're also able to emit signals from depths of20,000 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.

1. Why was the black box redesigned in 1965?

A. New materials became available by that time.

B. The early models didn't provide the needed data.

C. The early models often got damaged in the crash.

D. Too much space was needed for its installation.

2. What do we know about the black boxes from Air France Flight 447?

A. They have stopped sending homing signals.

B. They were destroyed somewhere near Brazil.

C. There is an urgent need for them to be reconstructed.

D. There is still a good chance of their being recovered.?

【答案】1. C 2.D

【解析】

1.?考點(diǎn)出處倒數(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。

2.?考點(diǎn)出處最后一段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D。
