The fact that aircraft may be vulnerable(易受攻击)to interference__19__the risk that terrorist may use radio system in order to__20__navigation equipment. 1.A.drivers C.engineers 答案: B B.pilots D.conductors

文章第一句已表明: 当今航空公司面对的最大的安全威胁不是持枪的恐怖分子,

而是手提电脑。所以对飞机上的这种事情最了解的应是飞行员,而不是 A、C、D 的那些人。 2.A.actions C.matters 答案:D B.events D.incidents 此处指飞机上发生的这类事情。本题同样考查了词义辨析。incident 指“较小

的事件, 插曲, 小故事”, action 是“(采取的)行动”之意, event 是“大事件”, matter 指“问 题,事情,或麻烦事”等,均不合适。 3.A.reason C.source B.effect D.story

答案:C 根据下句话得知“手提电脑,移动电话”等这些电子装置应是“干扰源”,而 不是受干扰的结果,受干扰的应当是飞机。reason 不合适是因为 reason 接 for 而不接 of,表示 “……的原因”。 4.A.and C.but 答案:C B.for D.so “没有确认”(unconfirmed)与“在增加”(increasing)中间应是转折关系,不是

递进、因果关系,所以不选 A、B、D。 5.A.advises C.ensures B.persuades D.warns

答案:A 因为下文用了 recommend(劝告)一词,所以这个组织应该是向航空工业提建议 的一个组织,这样才前后一致。 6.A.some C.all B.several D.no

答案:C 因为这种电磁的(electromagnetic)干扰对飞机航空的安全造成最大的威胁,所以 应该是所有的飞机都要有这样的禁令。 7.A.for C.by B.with D.during

答案:D 此处指飞机在飞行期间的一些对技术设备要求严格、要求高的时期,一定要严 禁使用此类装置,例如:起飞、降落等。critical 原意为“挑剔的,紧要危急的”,在此略有 转义;stage 原意“舞台”,此处意指“阶段,时期”,所以用 during。 8.A.particularly B.specially

C.unfortunately 答案:A 据上面解释,特别是起飞时。 9.A.looking C.waiting

D.possibly

B.calling D.asking

答案:B 有些专家要求更高,要求在飞行期间要禁用:call for 意为“需要,要求”;ask for 意为“要,索取”。 10.A.put C.given 答案: B B.left D.sent 表示目前使用这些设置的规矩都留了下来, 由那些 individual airlines 自己决定,

因为下文有表达:许多乘客还是想在飞机上办公。 11.A.carrying C.fixing B.taking D.using

答案:D 这种装置可以携带,不能使用,一旦使用会产生电磁效应干扰,所以选 D。禁 止使用,而不是禁止携带,fix 是“安装”,一般没有人专门上飞机安装。 12.A.possibility C.necessity B.difficulty D.idea

答案:B 推断出电磁效应是如何影响飞机的计算机,这在目前是件难事,如果不难,科 学家能解决,就不必有禁令了,所以选 difficulty。 13.A.must C.need B.should D.might

答案:D 表示“可能”。因为拿不准,所以用 might 表示可能,语气轻。 14.A.know C.guess B.tell D.think

答案:A 这些手提装置已广为人们所用,所以科学家是“知道”,而不是“猜”或“认 为”,tell 后缺少 sb。 15.A.aircrafts C.ships B.trains D.cars

答案:A 该文讲的都是航空,选 A(飞机,飞行器)。 16.A.restudy C.reproduce B.retell D.renew

答案:C 该句主语为 they,指的是那些有电磁效应的装置,因此不选 A、B。选项 C 表 义为“再现”;而 renew 意为“更新,重新开始”。 17.A.key C.step B.way D.trick

答案:B 因为这些装置在实验室里那些干扰还未能再现,所以科学家们就没有办法(have no way of doing)得知这种干扰是否危险。 18.A.dangerous C.helpful B.strong D.useful

答案:A 全文讲述的是电子产品的电磁干扰对飞机安全性的威胁,本空用 dangerous 点 明主题。 19.A.faces C.runs B.raises D.takes

答案:B 飞机容易受干扰攻击的这一事实增加了恐怖分子冒险利用无线电系统破坏航空 设备的可能性。根据最后一句话及全文的整体意思,说明飞机对干扰是非常敏感的,因此此 类装置对犯罪分子破坏飞机装备的可能性就增加了。 20.A.repair C.defend B.guide D.destroy

答案:D 恐怖分子只会冒险破坏,而不会去修理、引导等。 Ⅲ.阅读理解 The earth is the only planet that scientists think has life. Why does the earth have life while the other planets don't? For one thing, the earth just the right temperature. As the_third_planet from the sun,the earth seems to be just the right distance away. The planets which are closer to the sun are so hot that their surfaces bake(烘烤)in the sun. The farthest planets are cold balls. When the earth developed—which scientists believe may have happened about 4 billion years ago—many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe. Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth,and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit, you could walk around on Mars. You would have to bring your own air to breathe,because the air on Mars is too thin to breathe. Mars has the largest volcano(火山)in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected(未预料到的)sight on Mars is driedup river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far. 文章大意:文章介绍了地球存在生命的原因以及火星的情况。 is

1.Which of the following is NOT the reason that the earth has life? A.The earth is just the right temperature. B.The volcanos on the earth are lower than those on Mars. C.There is oxygen in the atmosphere of the earth. D.The earth seems to be just the right distance away from the sun. 答案:B 细节理解题。文中提到地球是可证实的唯一有生命存在的太阳系行星,其原因 包括地球温度合适、距太阳距离适中和大气里含有氧气等。B 项火山与此无关。 2.The underlined phrase“the third planet”in the first paragraph refers to________. A.the Sun C.the Earth B.the Moon D.the Mars

答案:C 词义猜测题。根据第一段中内容可知距离太阳第三远的行星指的是地球。 3.Which of the following about the Mars is NOT true? A.There could have been living things on Mars. B.Mars has the largest volcano in the solar system. C.There is almost no oxygen in the air on Mars. D.Mars is smaller than the earth,and it is quite a bit cooler. 答案:A 细节理解题。文章最后一段提到火星上有干涸的河床的迹象,但这一点并不能 证实火星上存在生命,因为还没有生命迹象,故 A 项不正确。其他三项都与文章相符。 4.Which of the following is probably the best title for the passage? A.The Earth B.The Moon C.Planets in the Solar System D.Mars is Most Like the Earth 答案:D 主旨大意题。文章先说明地球上存在生命的原因又对比了火星和地球,说明火 星是与地球最相似的行星。D 项做标题最为恰当。
