68、(二)这样做题名师解题语篇解读：本文是一篇议论文。文章指出，平均而言女人比男人更长寿。其中的原因是什么呢？作者从荷尔蒙、基因等方面给出了解释。36选A根据空格后的“In general, they can expect to live six or seven years more than men.”可知，空格处讲的是平均来看，女人的寿命更长。同时，空格处所表达的内容与文章第一句构成转折关系。所以A项正确。37选G此处为过渡句，解释什么是荷尔蒙并谈及它的作用。所以G项正确。38选D由空格后的“They help the body defend itself against some kind
69、s of infections.”可知，该段讲的是荷尔蒙的其他功能。所以D项正确。39选C由空格后的“Scientists are still not exactly sure . to age more slowly than a mans.”可知，本段主要讲了基因与衰老的关系。所以C项正确。40选E空格处的前两句谈及了两个观点。所以E项正确。阅读七选五系列技法2利用逻辑线索解题1从细节逻辑上判断因果关系在做题时最重要的是要读懂空白前后的句子，明白这几句话的确切意思，然后根据意思的连贯性或逻辑性从选项中选取正确答案。在读懂意思的基础上，判断它们之间的关系来进一步确认答案。因果关系主要指前后的
70、句子有着原因和结果之间的关系，这种关系往往说明了前因后果或者前果后因等情况。表示因果关系的连词有as a result“结果”；thus/therefore“因此”；so/such . that . “如此以至于”等。2从细节逻辑上判断转折关系转折关系主要指英语行文中后句对前句构成逆转逻辑关系。如果空格前后两句话之间是逻辑上的逆转，则空格处很有可能是个转折逻辑的句子。表示转折关系的连接词有：however“然而”；nevertheless“仍然，然而，不过”；nonetheless“尽管如此，依然，然而”；still“还；然而”；though“可是，不过，然而”；yet“然而”； in spi

97、out sibling_rivalry. Sibling rivalry does not necessarily stem from (源于) the desire to be the “favorite” among ones parents. In fact, sibling rivalry can also be attributed to a sort of natural competition that arises between people, especially those living close to one another.Already, childhood de

This observation is apparent in many sibling relationships, even my own. Yet, what can explain the change that happens?Perhaps, it has someth
99、ing to do with maturity (成熟). Maturity focuses on ones relationships, even those between siblings. Whether or not maturity helps create friendly terms between siblings is not entirely clear, but it is apparent that maturity helps to explain why siblings take focus away from creating antagonism (对立).
100、 If the old saying, “Blood is thicker than water”， is applied to sibling relationships, we find that genetic relationships can enhance social relationships.So, even if we want sibling relationships to be peaceful and loving, we cannot expect those friendly terms to exist always. What is important in
101、 this type of relationship is the concept of forgiveness.Forgiveness can heal any wound, and in the case of sibling relationships, it can be the path to a life of togetherness and solidarity (团结)Therefore, it is entirely true that we cannot pick and choose who is in our family. But, we can learn to
102、live together peaceably despite our differences. This not only applies to sibling relationships, but to all relationships in general. 语篇解读：手足之争不一定是源于希望得到父母更多的爱，还可能是出于一种人与人之间的自然竞争。本文作者对这一现象产生的原因及其发展和影响进行了分析和解读。1What does the underlined phrase “sibling rivalry” in Paragraph 1 mean?ASiblings competing
103、for more love from their parents.BParents hardly treating their children equally.CPeople liking to live close to one another.DStudents working hard together at their lessons.解析：选A词义猜测题。根据上下文(第一段第一句到第三句)的意思可知，sibling rivalry 在此处指“手足之争”，即兄弟姐妹们争相得到父母更多的爱。2According to the author, the relationships betw
104、een siblings will become _.Amore difficult to deal with Bmore and more importantCworse and worseDbetter and better解析：选D细节理解题。根据第二段第二、三句可知，兄弟姐妹之间的敌意不会持续下去，他们之间的关系会变得越来越好。由下文的论述也可得知答案。3Which of the following can lead to a peaceful and solid life?AThe concept of determination.BThe quality of forgivenes
105、s.CThe friendly relationships.DThe spirit of bravery.解析：选B细节理解题。根据第四段最后一句可知，原谅对稳固家庭关系很有帮助，有利于促进家庭的和睦与团结。4What should we do if we want to build good relationships?ATry our best to choose outgoing siblings.BBe always ready to help each other.CAccept all the different personalities.DTry to be quite dif

107、 therefore seem like pride. But you have to start somewhere, and International Business Machines (IBM) and the Ecole Polytechnique Federale de Lausanne (EPFL), in Switzerland, propose to start by replicating “in silico”， one of the brains building blocks.In a partnership announced, the two organizat
108、ions said they would be working together to build a simulation (模拟) of a structure known as a neocortical (新大脑皮质的) column on a type of IBM supercomputer that is currently used to study the molecular functioning of genes. If that works, they plan to use more powerful computers to link such simulated
109、columns together into something that mimics (模仿) a brain.In a real brain, a neocortical column is a cylindrical (圆柱形的) element about a third of a millimeter in diameter and three millimeters long. It is these columns, arranged side by side like the cells of a honeycomb, which make up the famous “gre
110、y matter” that has become shorthand for human intelligence. The Blue Gene/L supercomputer that will be used for the simulation consists of enough independent processors for each to be programmed to mimic an individual nerve cell in a column.The EPFLs contribution to the Blue Brain Project will be to
111、 create a digital description of how the columns behave. The database from its Brain Mind Institute will provide the raw material for the simulation. Biologists and computer scientists will then connect the artificial nerve cells up in a way that mimics nature. They will do so by assigning electrica
112、l properties (电能) to them, and telling them how to communicate with each other and how they should modify their connections with one another depending on their activity.That_will_be_no_mean_feat. Even a single nerve cell is complicated, not least because each one has about 10,000 connections with ot
113、hers. And nerve cells come in great variety relying, for example, on different chemical transmitters to carry messages across those connections. Eventually, however, a digital representation of an entire column should occur.Assuming that the growth of computing power continues to follow Moores Law,
114、the leader of IBMs side thinks it should be practical to mimic an entire human brain in silico this way in ten to fifteen years. Such an artificial brain would, of course, be a powerful research tool. It would allow neurological experiments that currently take days in a “web lab” to be conducted in
115、seconds. The researchers hope that their simulated brain will reveal the secrets of how certain psychiatric and neurological, disorders develop. But that is probably not the real reason for doing it. The most interesting question, surely, is whether such an artificial brain will be intelligent, or c
116、onscious, or both.语篇解读：对于人类来说，人脑是已知的最复杂的物体，也是科学无法解释的自然现象之一。国际商业机器公司和瑞士洛桑联邦理工学院尝试使用超级计算机模拟新皮质柱从而来模仿人脑。研究人员希望借此来探索人造大脑将会有什么功能，这样的人造大脑是否是智能的或者有意识的，还是二者兼而有之。5In a real brain, a neocortical column _.Alooks like the cells of a honeycombBis a simulation of a structureCis the famous “grey matter”Dcontains a
117、 large number of nerve cells解析：选D细节理解题。根据第三段最后一句可知，超级计算机中的每一个独立处理器被编程来模仿新皮质柱中的单个神经细胞，所以足够多的处理器被用来模仿新皮质柱中的许多的神经细胞。由此可见，在真的大脑中，一个新皮质柱包含大量的神经细胞。故选项D正确。6What does the underlined sentence “That_will_be_no_mean_feat” in Paragraph 5 indicate?AIt is rather difficult to connect the artificial nerve cells up.
118、BThe function of chemical transmitters is hard to understand.CA digital representation of an entire column is timeconsuming.DA single nerve cell is complicated to identify across connections.解析：选A推理判断题。根据第四段第三句和第五段第二句可知，单一的神经细胞是复杂的，而每一个神经细胞与其他神经细胞之间的联系还有约10 000次，所以生物学家和电脑科学家将人造的神经细胞连接到一起是一件相当复杂的事情。故
119、选项A符合题意。no mean feat为固定短语，意为“非常了不起；绝非易事”。7The fundamental purpose of doing the research is probably _.Ato simulate an entire human brain in silicoBto tell us how some certain disorders emergeCto discover how the artificial brain would workDto examine whether Moores Law is still functioning解析：选C细节理解题
120、。根据第六段最后两句可知，最有意义的问题是这样的人造大脑是否是智能的或者有意识的，还是二者兼而有之。显然这个研究的根本目的是为了探索人造大脑将会有什么功能。故选项C正确。单元检测B阅读理解提速练.阅读理解APatients in the early stages of Alzheimers disease often struggle to remember recently learned information, meaning they forget things like important appointments or where they left their keys. But
121、 it seems that these memories are not lost. They are still filed away in the brain somewhere; they just cant be easily accessed.Now, researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimers. The method relies on a technique that uses light to control genet
122、ically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it involves inserting light emitting (发光) equipment into the subjects brains, but the same principles still apply, the researchers said.“The important point is that this is evidence of concept. That is, even if
123、 a memory seems to be gone, it is still there. Its a matter of how to get it back，” said senior researcher Susumu Tonegawa.The team took two groups of mice, one genetically engineered to develop Alzheimers and one healthy. They then placed them into a room and gave them a mild electric shock. All of
124、 the mice showed fear when put back in an hour later. When placed in the room a third time several days later, the Alzheimers mice acted normally. They had forgotten the shock.The researchers were then able to bring back the memory of the shock by activating (激活) the cells in which the memories were
125、 stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells associated with the shock were activated.“Shortterm memory seems to be normal, on the order of hours. But for longterm memory, these early Alzheimers mice seem to be damaged，” said lead researcher Dheeraj R
126、oy. “Directly activating the cells that we believe are holding the memory helps them get it back. This suggests that it is indeed an access problem to the information, not that theyre unable to learn or store this memory.”语篇解读：通过对老鼠的实验研究，研究者发现在患有阿尔茨海默症的老鼠身上，能够通过激活储存记忆的细胞，使老鼠重得记忆。1What can we learn a

145、 live at home, and their parents take care of all their physical needs such as food and housing. _2_ Parents are also there to offer help and make sure that the students homework is done. During the school day, students rarely have free time. They go directly from one class to another. Teachers are
146、always around to tell the students what to do. _3_ So students can often complete their homework and reading in a short time._4_ They may be responsible for shopping, paying bills, and laundry. They also may have to cook their own meals. Their parents are not around to help with homework or even to
