⑧ 人生难免有离别。当我们面临分别时，也许会有李白 “浮云游子意，落日故人情”的依依不舍，也许会有“__________________，__________________”的大气豪迈。

①∠CAD=30°   ②BD= $\sqrt{7}$    ③S_{平行四边形ABCD}=AB•AC     ④OE= $\frac{1}{4}$ AD     ⑤S_△APO= $\frac{\sqrt{3}}{12}$ ，正确的个数是（   ）

下列诗句运用的修辞手法与其他三句不同的一项是（    ）

如图是某汽车维修公司的维修点在环形公路上的分布图．公司在年初分配给A，B，C，D四个维修点某种配件各50件．在使用前发现需将A，B，C，D四个维修点的这批配件分别调整为40，45，54，61件，但调整只能在相邻维修点之间进行，那么要完成上述调整，最少的调动件次为多少？说明理由．（注：n件配件从一个维修点调整到相邻维修点的调动件次为n）

    You have never seen 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（经受得住）almost any disaster makes them seem like something out of a magic 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（潜水艇）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（装置）was completely redesigned and moved to the back of the plane-the area least affected bu impact-from its original position in the landing wells（起落架舱). 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 ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel,the boxes can withstand massive force and temperatures up to 2,000℉.When in deep water,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.
