28、ut.Neither could other scientists who dealt with such problems.However,Halley had a friend named Isaac Newton.Who was a brilliant mathematician.Newton thought he had already which he had done it.He told Halley that the orbit of a comet had the shape of an ellipse.Now Halley set to work.He figured ou
29、t the orbits of some of the comets that had been observed by scientist.He made a surprising discovery.The comets that had appeared in the years 1531,1607 and 1682 all had the same orbit.Yet their appearances had been 75 to 76 years apart.This seemed very strange to Halley.Three different comets foll
30、owed the same orbit.The more Halley thought about it,the more he thought that there had not been three different comets,as people thought.He decided that they had simply seen the same comet three times.The comet had gone away and had come back again.It was an astonishing idea!Halley felt certain eno

35、h to eat.This must be one reason why dinosaurs died out.We can guess another reason.New kinds of animals came on the earth.Some had big brains and strong.They could kill dinosaurs.There may be other reasons that we dont know about yet.Scientists are are trying to make more discoveries about dinosaur
36、s.Dinosaurs were of many sizes and shapes.Some were as small as chickens,while some were about 90 feet long.There were also terrible rights between dinosaurs.They night have happened more than 100 million years ago.Though there was no man to see any of the fights,we can be told by the animals footpr

40、g the nest-box again this year.The male is the house-hunter but the female will make the final choice.He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.Among many birds that nest in holes,the male has a light-coloured
41、 patch on its plumage(鸟羽)which acts as signal for drawing the females attention to a suitable nesting-place.Unlike the blue tit,the redstart(红尾鸲)may be only the male that strikingly coloured and the female is not beautiful.A few years ago I was lucky enough to spot a pair of redstarts in action in a
42、 Walsh wood.The male was leading an interested female to holes that he had previously(先前)checked out.He sat at the entrance of each hole and put his head on to show off his white forehead,or his head in to reveal(显露)his tail.If the female failed to react to his visual signals,the male sometimes sang
43、 for extra effect,while gliding towards her on spread wings and tail.Once the female accepts by following the male through the hole the displays stop,you must be at the right place at the right time to watch them.68 How do the blue tits choose their nest?A.They choose their nest together.B.The male

48、extinct in over 100 years.The panda,native only to China,is in danger of becoming extinct in the next 25 years.This week,Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant the embryo i
49、nto a host animal.The entire procedure could take from three to five years to complete.“The nuclear transfer(核子移植)of one species to another is not easy,and the lack of available(capable of being used)panda eggs could be a major problem,”Kraemer believes.“They will probably have to do several hundred
50、 transfers to result in one pregnancy(having a baby).It takes a long time and its difficult,but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk,so it is worth the effort,”adds Kraemer,who is one of the leaders of the Project at Texas A&M,the fi

64、appear 看起来好像是；suit,fit 是及物动词，不与 to 连用。28.D offer 与 provide 的用法分别为：offer 后跟双宾语，即：offer sb.sth.；provide 要用下列形式：provide sb.with sth.和 provide sth.for sb.。29.C provide 常用于 explain to sb.sth 或 explain sth.to sb.结构。30.B eventually 最后,终于；typically 典型地，典型的做法是；particularly 特别地；especially尤其地；特别地；句意：典型的做法是，他会来
65、晚然后说对不起。31.A attach(to)附加，系上，附上，attack 袭击，攻击；attract 吸引；attribute 把 归功于，是由于。32.A show 后要跟双宾语，即 show sb.sth.;把忘在哪儿要用“forget sth.+介词+地点。”33.D。考查冠词。be in danger of 为固定短语，意为“有危险的”。34.D。考查非谓语动词。此处应用不定式的主动形式表示被动意义。35.C。考查短语动词。hold out for 意为“坚持要”。36.C。考查时态。根据语境可知，Alice 过去打篮球和网球，但现在已放弃，故此空用一般过去时。37.D。考查动词短
66、语。die away 表示“（风、声音等）渐息，渐弱”。38.D。考查非谓语动词。过去分词短语作原因状语，相当于原因状语从句 Because he was left in the care of his grandmother.39.C。考查交际用语。that depends 表示“视情况而定”。40.A。考查名词性从句。第一空用 what 引导主语从句；第二空用 where 引导宾语从句。完形填空36.C根据后文可知，天正“下着雨”。37.A余者不及 signing 含义准确。38.DA、B 不能接 sth.to do,C 接 sth.to do 时作“认为”讲，在此不合语境。39.C打车的
67、人当然希望过往的出租车能“停”下来。40.A 根据语境可排除 B、C、D（thought）接从句时，一般作“认为”讲，不合文意。41.D全句意思为：我要是不曾有乘“出租车”这一念头该多好啊！car 表意不准确，它除了指出租车外，还可指其它车子。42.B“脱下”帽子以便倒掉积水。43.B将水从帽边倒“出”。44.A从第十九个空格后的 without understanding what the driver had said to me 中可判断出。45.D告诉司机的应是所去的地方，即“地址”。余者不合习惯表示法。46.B从他不再向住宅区送客来看，他已“下”班。47.Cpick up 系固定搭配
68、，意为“搭载”。48.D根据习惯表达法选定。49.A“到这时为止”雨下得更大了。50.C鸣喇叭来催促的车子一定是“在后面”。51.B鸣喇叭是“要求”前面的车子启动。余者不合语境。52.A根据从句谓语的虚拟语气形式选定。53.C从词的用法角度考虑。54.C我知道在未明白司机话的情况下，我“不该”上车。55.B从句表示的是让步关系。阅读理解56.B（细节理解题。从第一段第二、三行可以找到答案）。57.C（辨别正误题。根据第三段的“Nearly 15,000 plant species are native to Yunnan Province”可以判断 C 项错误，而其他三项的表述都可从文中找出证
69、据证明它们是正确的，所以答案是 C 项。）58.A（细节理解题。从末段的第二、三行可以得知答案。）59.D（观点态度题。末段第一行表明了作者对旅游业的看法是兼顾利与弊，这才是最客观的观点，所以正确答案是 D 项。）60.C 从第一段第一句话可以看出，哈雷的发现是在研究其他科学家的观察中得出的，其它选项与本文内容不符。61.B 首先确定彗星下次出现的时间是 1758 年，然后确定这一事件距离他预测的时间是 53年，再用 1758 减去 53 年就可以得出正确答案。62.D 通读全文，就可以看出全文的大意，文章的每一段都在介绍哈雷及他的发现，另外也可以从文章的首尾句看出本文的主旨大意。63.C 本
70、文第一句话说哈雷是一个英国科学家，故 A 项是错误的；从第二句可以看出，哈雷的发现是在研究其他科学家观察的基础上得出的，所以 B 项是错误的；从第二段最后一句可得知哈雷彗星的轨道是椭圆形的，所以排除 D 项。本题题材还可以根据自己的常识来选出 C项为正确答案。64.B（文章第一句话“Millions of years ago dinosaurs lived on the earth.”可知恐龙生活于几百万年前。）65.D（文章第一段介绍恐龙灭绝的一个原因是缺乏食物，而 B 项是导致食物缺乏的一个原因。）66.B（第二段介绍恐龙灭绝的另一个原因是出现了更大、更强、更聪明的生物，它们有可能把恐龙杀
71、灭。）67.C（从文章第三段第二句话“Scientists are trying to make more discoveries about dinosaurs.”可知，科学家正在对恐龙进行更进一步的研究，由此推知恐龙值得研究。）68.D 细节题。从第 1 段第 2 句话 The male is the house-hunter but the female will make the final choice 可以做出正确选择。69.C 判断题。从第 3 段第 1 句 I was lucky enough to spot a pair of redstarts in action in a
72、 Walsh wood 和文章第三、四段的内容可知答案为 C。70.D 语义理解题。根据 A few years ago I was lucky enough to和you must be at the right place at the right time to see them 可知答案为 D。71.A 推断题。从文章内容来看，文中不仅提到了鸟的一些习性，而且对雄鸟如何吸引雌鸟入巢了解得很清楚，可见作者可能是一位研究鸟类的专家。72.B 语义理解题。从第 2 段内容可知，“诺亚方舟”工程的目标是把濒临灭绝的动物的蛋(卵)、胚胎、精液和 DNA 储存在液体氮中，如果某一种动物濒临灭绝时，
73、将来可以重现这一动物。73.A 细节题。从第 6 段第 1 句话 The nuclear transfer(核子移植)of one species to another is not easy,and the lack of available(capable of being used)panda eggs could be a major problem可以做出正确判断。74.C 主旨题。从文章内容来看，无论是中国还是世界克隆熊猫还没有成功，所以排除 A、B项；D 项内容明显与文章内容不符，故排除。所以“探索克隆熊猫的可能性”应该是这篇文章的标题。75.D 判断题。此题 B 项的干扰性较强
74、，但由于它没有说明是 Chinese scientists，所以应排除。A、C 项明显与原文不符。根据文章第 3 段第 1 句可知答案非 D 莫属。阅读表达76.Living Longer or Not77.I think we are knocking at the door of immortality.78.we will see it/we can reach that goal79.With science and technology developing quickly I think it is possible for humans to live longer in the
