13、others and sisters is obviously different from the realistic relationships that exist between brothers and sisters. Anyone who has had either a brother, a sister or both will know a little bit about sibling_rivalry. Sibling rivalry does not necessarily stem from (源于) the desire to be the “favorite”
14、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 describes and shapes the development of the relationships between siblings. So that type of hostile relatio
15、nship may not continue throughout the siblings lives. This observation is apparent in many sibling relationships, even my own. Yet, what can explain the change that happens?Perhaps, it has something to do with maturity (成熟). Maturity focuses on ones relationships, even those between siblings. Whethe
16、r 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). If the old saying, “Blood is thicker than water”， is applied to sibling relationships, we find that gene
17、tic 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 this type of relationship is the concept of forgiveness.Forgiveness can heal any wound, and in the case
18、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 live together peaceably despite our differences. This not only applies to sibling relationships, but to a
19、ll 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 for more love from their parents.BParents hardly treating their children equally.CPeople liking to live

21、etter 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 forgiveness.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

23、 to humanity is the human brain and not only is it complex, but it is one of the few natural phenomena that science has no consciousness of. To try to replicate (复制) something that is so poorly understood may therefore seem like pride. But you have to start somewhere, and International Business Mach
24、ines (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 organizations said they would be working together to build a simulation (模拟) of a structure known as
25、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 columns together into something that mimics (模仿) a brain.In a real brain, a neocortical colu
26、mn 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 “grey matter” that has become shorthand for human intelligence. The Blue Gene/L supercomputer th
27、at 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 create a digital description of how the columns behave. The database from its Brain Mind In
28、stitute 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 electrical properties (电能) to them, and telling them how to communicate with each other and how they
29、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 others. And nerve cells come in great variety relying, for example, on different chemical tran
30、smitters 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, the leader of IBMs side thinks it should be practical to mimic an entire human brain in sili
31、co 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 seconds. The researchers hope that their simulated brain will reveal the secrets of how cert
32、ain 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 conscious, 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
33、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 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
34、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.BThe function of chemical transmitters is hard to understand.CA digital represent
35、ation 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 d
36、oing 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。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。
