It turns out，a first name and Chinese heritage aren’t the only things the threeyearolds have in common. The girls’ mothers—Holly Funk and Diana Ramirez—met on a website for parents who had gone through international adoptions. After a lot of emails comparing photographs and biographical details，DNA testing proved the families’ suspicions: The girls are probably fraternal twins.‎ ‎“I was in shock，” said Ramirez，who lives with her husband Carlos in Pembroke Pines，Florida.“Well，now this is for real.”‎ The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin(亲属). The site that Funks and Ramirezes used has a membership of 137 people，with 15 sets of twins and 7 sets of siblings whose relationships have been confirmed.‎ At a reunion at Chicago’s O’Hare International Airport，Mia Diamond Funk and Mia Hanying Ramirez shyly surveyed each other，and then reached for each other’s hand.‎ DNA tests establish an 85 percent probability that the girls are at least halfsisters. Scientists do not have a biological parent to test and reach a greater certainty，but given their ages and physical similarities，experts say it is likely they are fraternal twins.‎ Douglas and Holly Funk hope to bring their Mia to Miami in October. Both sets of parents say they are committed to staying in touch and often let the two sisters talk to each other on the phone.

Almost all the rest is dark matter and dark energy，unknown forces that puzzle astronomers.‎ Observations in recent years have changed the basic understanding of how the universe evolved and have indicated how little is known about the major forces and substances that shaped our world.‎ Astronomers now know that luminous(发光的) matter—stars，planets and hot gas... accounts for only about 0.4 percent of the universe. Nonluminous components，such as black holes and intergalactic(星系间的) gas，make up 3.6 percent. The rest is dark matter，about 23 percent，and dark energy，about 73 percent.‎ Dark matter，sometimes called “cold dark matter”，has been known for some time. Only recently have researchers come to understand the key role it played in the formation of stars，planets and even people.‎ ‎“We owe our very existence to dark matter，” said physicist Paul Steinhardt. “Dark matter dominated the structure formation in the early universe，” Steinhardt said. “For the first few billion years dark matter contained most of the mass of the universe. You can think of ordinary matter as a froth(泡沫状物) of an ocean of dark matter. The dark matter dumps and the ordinary matter falls into it. That led to the formation of the stars and galaxies(星系). Without dark matter，there would be virtually no structure in the universe.”‎ The nature of dark matter is unknown. It cannot be seen or detected directly. Astronomers know it is there because of its effects on celestial(天上的) objects that can be seen and measured. But the most dominating force of all in the universe is called dark energy, a recently proven power that astronomers say is causing the galaxies in the universe to separate at a faster and faster speed.‎ ‎6．We know from the text that ________.‎ A．all visible stars are very important in the universe B．the basic understanding of the universe evolution was totally wrong C．dark matter is also known as dark energy D．dark energy makes up about three quarters of the universe ‎7．The text tells us “dark matter” ________.‎ A．plays an important part in forming stars，planets and humans B．has been fully understood by researchers C．remains an unimportant force to the universe like dark energy D．has nothing to do with the formation of the universe today ‎8．“The major forces and substances that shaped our world” (in Para. 2) refers to ________.‎ A．luminous matter B．nonluminous matter C．dark matter D．ordinary matter ‎9．According to Paul Steinhardt，our existence today ________.‎ A．depends mainly on dark matter B．has something to do with ordinary matter C．results from the formation of celestial objects D．evolves from the mass of the universe ‎10．Which of the following is the best title for the passage?‎ A．Dark Matter or Dark Energy B．The Formation of the Universe C．Dark Forces Dominate the Universe D．Unknown Forces Puzzle Astronomers 答案 课外练习区 Ⅰ.1.greedy　greedily　greed　2.rudely　rude　3.annoying　annoying　annoyed　4.puzzles　puzzling　5.balance　balance Ⅱ.1.turn my back on　2.drop out of　3.to be exact ‎4．give away　5.dream up Ⅲ.1.What/How about the two of us going out for a walk?‎ ‎2．where there is water　3.who is responsible for　4.is no better than　5.very unsatisfying Ⅳ.‎ ‎1．B　[“make＋life＋形容词”， 而且后面为比较级， 所以两个空应同为形容词同为比较级。]‎ ‎2．B　[句意为：真是奇迹！在这么短的时间里他们就完成了多达一半的工程。no more than仅仅，和……一样少；no less than不少于，多达；not more than至多，不超过；less than少于；比……少得多。由句意可知，B项正确。]‎ ‎3．A　[句意为：我会把书放在你原先放的地方，并在放书的地方做一个标记。第一个空是由where引导的地点状语从句；第二个空是由where引导的定语从句，修饰先行词place，where也可改为at which。本题将定语从句和地点状语从句结合起来考查，增加了试题的难度。判断where引导的是定语从句还是地点状语从句，关键是看where前面有没有表示地点之类的名词作先行词，如有就是定语从句，反之就是地点状语从句。]‎ ‎4．D　[在It is...that...强调句型中，强调人时，that可用who, whom (只能用于强调宾语)代替。]‎ ‎5．B　[I couldn’t agree more表示我完全同意，符合语境。句意为：——汤姆，这周末出去野餐怎么样？——完全同意。我喜欢接近大自然。]‎ ‎6．C　[句意为：很多人坚持认为荧屏暴力是社会上犯罪和攻击性行为的主要原因之一。childish孩子气的，幼稚的；artificial人工的；假的；aggressive攻击的，挑衅的，好斗的；heroic英勇的，英雄的。根据句意，C项正确。]‎ ‎7．B　[短语be determined to do sth.的逻辑主语是句子的主语，所以可以直接用形容词短语determined to do作状语；remaining adj.剩下的，剩余的，通常作前置定语。]‎ ‎8．A　[句意为：让丽萨吃惊而又恼怒的是，她发现其他人不等她就走了。to one’s annoyance 让人恼怒的是；to one’s amusement 让人开心、好笑的是；to one’s relief 让人欣慰的是；determination不构成该结构。根据句意，A项正确。]‎ ‎9．C　[句意为：秘书和打字员已经使用过它了，搜集他们的评论是个不错的主意。此处from表示来源。]‎ ‎10．B　[be annoyed with sb.at sth.因某事对某人生气。]‎ ‎11．A　[句意为：由于这个男孩想尽量自立，所以他拒绝了父亲的帮助。turn down拒绝，符合句意。turn away撵走，把……打发走；turn off关掉；turn up出现；到达。]‎ ‎12．A　[句意为：这家宾馆太糟糕了！首先，房间太小。其次，淋浴器也坏了。to start/begin with首先；after all毕竟；in reality实际上；as a whole总体说来。做好本题，要把信息词then与to start with对应起来。]‎ ‎13．A　[句意为：如果一个人没有睡够觉的话，那么在白天他的行为就会表露出来。give away赠送；泄露；表露；give up放弃；give in屈服；让步；give back返还；归还。]‎ ‎14．C ‎15．A　[句意为：——你怎么啦？——走了这么长的路，我的腿没力气了，我再也不能走了。give out筋疲力尽；give off发出，放出(气味、热、光等)；give in 屈服，让步；give up 放弃。根据句意A项正确。]‎ Ⅴ.内容解读 这是一个感人的故事：一个感染了HIV病毒的孩子Tyler，面对残酷的人生结局——死亡，他仍然非常乐观，对生活充满着美好的向往。‎ ‎1．C　[由第1空后面的an educator and health care provider可知，前面缺少表示“作为”的介词来连接后面的双重职业身份，因此用as。 ]‎ ‎2．D　[从下文可知，“我”特别了解到了Tyler这个弱小的家伙身上有着巨大的勇气(courage)。pleasure快乐；pain痛苦；sorrow悲伤，都不符合语意。]‎ ‎3．B　[be born infected with HIV表示“出生时携带HIV”，从后半句his mother was also infected和后一句可以推知答案选B。]‎ ‎4．B　[从上文提示可知，他依赖药物治疗，这使他能(enable)活下去。cause引起；make使得，应该用make sb. do sth.结构；lead导致，应该用lead to sth.。]‎ ‎5．A　[从该句中的oxygen(氧气)可知，他需要额外的氧气来支持他的呼吸(breathing)，其他选项不符合语境。]‎ ‎6．B　[根据下文语意可知，Tyler不愿意放弃他童年的快乐时光，此处语意表示他的心理状态，用be not willing to不乐意，不愿意，符合语境。]‎ ‎7．B　[所以“我们”经常(not unusual)可以看出Tyler背着装满药物的背包，后面小车中拖着(drag)氧气瓶，在后院玩耍、跑步。]‎ ‎8．A　[参见7题解析。从常识可知，车在后面，应该是拖着(drag)，而不是carry“携带”；push推；take带走。]‎ ‎9．B　[从上下文可知，“我们”都对Tyler的那种努力活下去的纯真快乐(joy)印象深刻。character性格；moment时刻；excitement兴奋。]‎ ‎10．C　[从常识判断，他母亲也是苦中作乐，常取笑(tease)他，告诉他跑得太快(fast)了，以致于他需要穿红色衣服，以便她透过窗户看他的时候能够很快发现(spot)他。comfort安慰；scold指责；praise表扬，都与语境不符。]‎ ‎11．D　[参见10题解析。slowly和happily不符合语境，quickly强调动作迅速、敏捷，而fast则强调速度快，故D项符合语境。]‎ ‎12．B　[参见10题解析。spot在这里表示“发现，看见”。]‎ ‎13．C　[从上下文可知，这致命的病最终消耗了Tyler的生命。wear down(使)消耗，损耗；tear down拆毁，拆卸；break down作“垮掉”讲时应表达为Tyler’s health broke down; kick down踢倒。]‎ ‎14．B　[此处是so引起的倒装结构，表示“他感染了HIV的母亲也如此”，所以选B项。]‎ ‎15．A　[apparent明显的，显然的；hopeless无望的；sure跟从句时不能是it作主语；terrible可怕的，糟糕的。语境表示“很明显Tyler活不了了”，所以选A项。]‎ ‎16．D　[他母亲跟他聊起了死亡(death)的话题。由后面一句可知答案选D项。]‎ ‎17．C　[他死前几天示意(sign)“我”到他病床边。wave招手，挥手，一般不跟不定式。]‎ ‎18．A　[由常识判断，他濒临死亡，肯定很虚弱，只能轻轻地对“我”说(whisper)。B、C两项不符合语境，D项后面通常不跟直接引语。]‎ ‎19．C　[Tyler说他不害怕(scared)死亡，但他死后，要给他穿红色(red)衣服，这样在天堂他母亲就能很容易地认出他来。根据语境选C项。]‎ ‎20．A　[文中11空后有提示。解析参考19题。]‎ Ⅵ.语篇定位 本文是一篇逸闻趣事类文章。两位美国母亲从中国收养了两个女孩。两位母亲通过在网上比较两个女孩的照片发现，她们长得很像，然后进行DNA检验，结果证明，这两个孩子很可能是双胞胎。‎ 长难句分析 Both sets of parents say they are committed to staying in touch and often let the two sisters talk to each other on the phone.‎ be committed to doing sth.表示“承诺干某事”。句意为：双方父母都说他们准备保持联系，经常让两个姐妹通过电话通话。‎ ‎1．D　[推理判断题。两位母亲都给女儿取了Mia这个名字，后来在网上交流时才发现两个女孩长得很像，因此断定两个母亲取名时是无意的，仅是一种巧合。]‎ ‎2．B　[细节理解题。从文章第五段中的“The Internet and Web groups revolving ‎ around international orphanages are increasingly being used to link adopted children with biological kin(亲属)．”可知答案。]‎ ‎3．C　[细节理解题。文章倒数第二段说科学家还没有女孩亲生父亲或母亲的DNA，因此不能作出确切的判断。]‎ ‎4．B　[细节理解题。从第四段Ramirez所说的话可以看出她非常吃惊，但还是相信眼前发生的一切。]‎ ‎5．A　[标题归纳题。这两个姐妹分别被两个家庭收养，最终得以团聚。A项最能体现本文的中心。]‎ 语篇定位 地球、月亮、太阳和肉眼可见的星体还占不到宇宙的1%。而约96%都是暗物质和暗能量。这使天文学家感到困惑。近年来的观察改变了人们对宇宙演变历史的认识，同时也说明了人们对塑造宇宙的那些物质和作用力知之甚少。‎ ‎6．D　[细节理解题。根据第三段最后一句中的“dark energy，about 73 percent”可知，正确答案为D项。原文中的account for与make up同义，表示“占(比例)”。]‎ ‎7．A　[细节理解题。通读全文可知，近年来的观察改变了天文学家对于宇宙演变历史的认识，也就是直到最近天文学家才认识到：dark matter(暗物质) 又称为“cold dark matter”，在宇宙早期结构形成的过程中起主导作用。其他选项的陈述都与原文不一致。]‎ ‎8．C　[推理判断题。根据第五段第二句话可知，暗物质(dark matter) 在宇宙早期结构形成的过程中起着支配的作用。]‎ ‎9．A　[细节推断题。第五段第一句话告诉我们，我们今天的存在应归功于暗物质，即暗物质决定了我们的存在。]‎ ‎10．C　[标题归纳题。全文的内容可以概括为：科学家最近认识到暗物质被证明是存在的一种能量，这种能量正影响着整个宇宙的构成，并主宰着宇宙。]‎ ‎　　‎
