This consistent and orderly time system, based on a grid of time 21 , seems so natural that people 22 give it a moments thought. So you may find it surprising to learn that prior to the late 1800s each community 23 its own time by looking at the sun. When the sun shone directly overhead in Washington, D.C., for example, it was 12:00 noon there; up the road in Philadelphia, 24 , it was 12:07, and in Boston it was 12:24. To measure time with absolute accuracy, it is necessary to move the clock about one minute for every twelve miles of distance; so according to “sun time” your pocket watch would be slightly 25 if you ventured only a few miles down the road.It was not until the advent of widespread railroad travel that a need 26 for 27 time. At one point over 300 local times were honored within the 28 , making it literally impossible for trains to arrive consistently on time 29 . As a result, in 1883 the continental United States was divided into four time longitude. The standardization resulting from this system 30 so helpful that in 1884 the International Meridian Conference applied the same procedure to establish time zones around the world.21.A.areasB.districtsC.zonesD.divisions22.A.usuallyB.neverC.onlyD.rarely23.A.madeB.establishedC.arrangedD.founded24.A.howeverB.thereforeC.meanwhileD.by contrast25.A.differentB.wrongC.incorrectD.mistaken26.A.arrivedB.raisedC.happenedD.arose27.A.regularizedB.organizedC.correctedD.standardized28.A.stateB.countyC.worldD.country29.A.everywhereB.anywhereC.nowhereD.somewhere30.A.was provedB.has been provedC.was provingD.proved答案21. C. 时区time zone, 是固定词组。22. D. 人们习以为常了，所以很少想到它，选rarely, 经常想起、从不想起和只想起它都不合理。23. B. 句意应为每个地区都确立自己的时间，只有establish可以表示建立制度。24. A.根据上下文可判断出此处为转折对比关系， 而by contrast 表示相反的对比，所以选however。25. C. 根据“太阳时”，只要离开几英里，表就会有一些不准，而不是不同、错误或误解。26. D. 需要出现应该搭配的动词是arise。27. A. 是需要调整时间，而不是使时间有组织、改变或标准化。28. D. 根据上下文，是在美国境内有300多个地区时。29. A. 根据文意，火车不可能在每个地方都准时，所以选everywhere, 和impossible 构成部分否定。30. D该系统被证明很帮助，应该用prove的主动形式，时态用一般过去时。2语法填空 阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空，并将答案填写在答题卡标号为31-40的相应位置上。字数：147完成时间：8分钟难度：* Usually male butterflies are more brightly colored than the female. The female have bigger and heavier bodies, 31 they carry the eggs. The bright colors of the male help to attract the female, and the duller colors of the female make them 32 likely to be caught by enemies before they 33 (lay) their eggs. 34 butterflies have a bright pattern colors on the upper surface of their wings which are shown 35 flying. But when they rest on a tree or 36 (leaf) they close their wings. On the undersides of their wings there are green and brown marks 37 look like the tree or leaves. They are then difficult to 38 (see). Many butterflies have round marks on their wings that look like eyes. When they are resting, their wings are closed, and these cannot be seen When a bird sees 39 , and begins to attack it, the butterfly 40 open its wings. The bird thinks that it sees two eyes staring at it, and so it is frightened, and flies away.答案31since 321ess 33have laid 34Some 35whenwhile 36leaves 37whichthat 38be seen 39one 40would 31since，“由于，既然”表原因。 321ess，从上下文可知此处是“雌飞蛾的较死板的颜色使她们在产完卵之前较少有可能被敌人抓住”。 33have laid，由before可知考查动词的现在完成时态。 34Some，不定代词，“一些”。 35whenwhile，whenwhile+ving分词相当于由when引导的时间状语从句，“正在飞时”。 36leaves，leaf的复数形式是leaves。 37whichthat，关系代词，引导限制性定语从句? 38be seen，考查动词不定式的被动语态，意为“然后他们很难被看见”。 39one，不定代词，指代任意一只butterfly。 40would，表一种必然的动作或经常的动作。3阅读理解 阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。词数：334完成时间：7分钟难度：* Yi So-yeon, an engineer from Seoul, returned to Earth on Saturday after 11 days aboard the International Space Station (ISS), along with Russian cosmonaut Yuri Malenchenko and US astronaut Peggy Whitson. A technical problem turned a routine (常规) return to Earth into a sharper than usual descent (下降) that tested the group members stamina and courage. They landed in the Kazakh steppes ( 大草原) about 420km (260 miles) wide of their target. During the descent there was some kind of fire outside the Soyuz capsule because we were going through the atmosphere, Yi said. At first I was afraid, but the two other guys looked okay, so I tried to look okay too. Yi smiled and joked her way through a 10-minute news briefing at Star City, the wooded Sovietera cosmonaut training centre on the edge of Moscow. However, Malenchenko and Whitson looked tired and thin after nearly six months in space. Their answers were short and Whitson needed support to balance when she walked. The 29-year-old Yi has become famous in South Korea since the take-off but she brushed this aside and said she has had little contact with friends or family since returning. In fact, they are the heroes right now, Yi said, referring to Malenchenko and Whitson. Im just a beginner and a little ashamed to say that I am a hero. She did, though, relate a more light-hearted incident on the ISS. I sang Fly Me to the Moon Yi said about the 1950s pop song. Its my favorite song from university although at that time I didnt know I would be an astronaut. The capsules so-called ballistic re-entering made the group members face twice the usual pull from the centre of the earth. The flames Yi described may have been caused by friction (摩擦) heating the capsule as it fell through the atmosphere. Whitson told reporters that Saturdays ballistic landing, was irregular but not an emergency. The Soyuz has been through its history very reliable and there has obviously been some issue in the last couple of descents which went ballistic, but Im sure the engineers will determine what the problems are and get them fixed, she said. In October, a Soyuz capsule carrying Malaysias first space tourist touched down about 200 km (125 miles) off course in a similar ballistic landing caused by a technical problem. The Soyuz is the worlds longest-serving manned space capsule. An early version of the craft, the Vostok, carried the first person into space in 1961. Whitson, 48, has become the American with the longest amount of time in space with 377 days.41. Whats the main idea of the passage? A. Flight in space is very dangerous B. Not everybody can go into space C. Fearful landing tests the Korean astronaut D. Yi didnt know she would be an astronaut when she was young42. The reason why Yi Suo-yeon felt afraid at first was that _. A. a fire was caused by the friction B. she had no such experience before C. she was not brave enough D. the other two didnt help her43.

Whitson became energetic when they landed on earth C. the two other guys were not afraid during the descent D. the Soyuz, an unmanned space capsule, had a long history44. The underlined phrase in this passage means _. A. out of work B. out of control C. in the wrong direction D. in danger45. We can conclude from this passage that _. A. experience is very important for astronauts to ensure safety B. Yi Suo-yeon will never return to the space station C. people are not willing to experience the space flight D. we should draw a lesson from the accident答案 本文讲述Yi Suo-yeon与另外两名宇航员在太空站11天后返回的不平凡经历。 41. C。主旨大意题。令人恐惧的着陆让进入太空的韩国宇航员经受了一次考验。42. B。细节理解题。根据第六段推理得出, Yi开始时恐惧的原因是以前没有过这种经历。43. C。由“At first I was afraid, but the two other guys looked okay.”判断得出答案。44. C。词意猜测题。off course偏离轨道。45. A。推理判断题。有上下文推理可得:飞行员的经验在旅途中能够对安全起很大作用。4写作训练 请根据下列信息，用英语写一篇关于2008年诺贝尔奖化学奖得主华人科学家钱永健教授的简介 写作内容 钱永健教授的简介提示：姓名：钱永健国籍：美国出生年月：1952年出生地：纽约获奖及相关情况：2008年诺贝尔化学奖，其研究为生物和医学试验带来革命。其父亲是名机械工程师，堂叔是我国著名科学家钱学森。钱永健教授是自诺贝尔奖颁发逾100多年来，第七位获诺贝尔奖的华人科学家。教育及工作经历：16岁获“少年诺贝尔奖” ，20岁，在哈佛大学获得物理和化学学士学位，现供职美国加州大学圣迭戈分校化学及药理系。写作要求 1只能使用5个句子表达全部内容： 2文中不能出现真实姓名和学校名称。评分标准 句子结构准确，信息内容完整，篇章结构连贯。写作向导 1时态：人物介绍应根据人物不同时期做的事情来使用不同的时态。 2可用词汇与句型：the Nobel Prize in Chemistry for2008诺贝尔化学奖，Roger Y.
