8、 store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.In a recent study, Professor Betsy Sparrow conducted some experiments.She

9、 and her research team wanted to know the Internet is changing memory.In the first experiment, they gave people 40 unimportant facts to type into a computer.The first group of people understood that the computer would save the information.The second group understood that the computer would not save

10、it.Later, the second group remembered the information better.People in the first group knew they could find the information again, so they did not try to remember it.In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet.The

11、information was in a specific computer folder (文件夹)Surprisingly, people later remember the folder location (位置) better than the facts.When people use the Internet, they do not remember the information.Rather, they remember how to find it.This is called “transactive memory”According to Sparrow, we ar

12、e not becoming people with poor memories as a result of the Internet.Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize large amounts of information so that they are able to find it at a later date.This doesnt mean we are becoming eithe

13、r more or less intelligent, but there is no doubt that the way we use memory is changing.文章大意：本文是一篇说明文。随着互联网用户越来越依赖互联网来存储信息，人们的记忆力会下降吗？专家们通过研究表明互联网正在改变我们记忆的内容和方式。1The passage begins with two questions to _B_.Adescribe how to use the InternetBintroduce the main topicCshow the authors attitudeDexplain

14、 how to store information解析：推理判断题。由第一段“Experts are wondering if the Internet is changing what we remember and how.”可知，专家们想知道互联网是否改变了我们所记忆的内容和记忆方式。所以判断出文章以两个问题的形式开头就是要引出文章的主题。故B选项正确。2What can we learn about the first experiment? _D_ASparrows team typed the information into a computer.BThe two groups

15、remembered the information equally well.CThe second group did not understand the information.DThe first group did not try to remember the information.解析：细节理解题。由第二段“People in the first group knew they could find the information again, so they did not try to remember it.”可知，第一组的人知道他们可以再次找到这些信息，所以他们并没有

16、努力去记住这些信息。故D选项正确。3In transactive memory, people _A_.Aremember how to find the informationBkeep the information in mindCchange the quantity of informationDorganize information like a computer解析：细节理解题。由倒数第三段“When people use the Internet, they do not remember the information.Rather, they remember how t

17、o find it.This is called transactive memory”可知，当人们使用互联网时，他们不记得这些信息。相反，他们记得如何找到它。这就是所谓的“交互记忆”。所以在“交互记忆”中人们记得如何查找信息。故A选项正确。4What is the effect of the Internet according to Sparrows research? _C_AWe are becoming more intelligent.BWe have poorer memories than before.CWe are using memory differently.DWe

18、need a better way to get information.解析：推理判断题。由最后一段“This doesnt mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.”可知，这并不意味着我们变得更聪明了或者更不聪明了。但毫无疑问，我们使用记忆的方式正在发生变化。所以判断出Sparrow的研究表明互联网的影响是它使我们记忆的方式不同了。故C选项正确。.七选五根据短文内容，从短文后的选项中选出能填入空白处的最

19、佳选项。选项中有两项为多余选项。Castles (城堡) and temples wear away after hundreds of years, but the symbols and words on the stone often survive.1_D_ E-books came from the development of science and technology, and books can be read online.Many people believe that regular books will be one day replaced by ebooks.Bo

20、oks and ebooks share lots of similarities.They are both items created by great minds. 2_E_ You can draw lines or highlight some details on books or e-books as notes.The notes can be kept for a long time.3_A_ Firstly, books dont have to be charged, while e-books need electricity if we want to read th

21、em.Meanwhile, spending too much time reading e-books may do harm to our eyes.Moreover, e-books dont share the same weight when held in the hand as regular books, nor do they give that sense of fulfillment that comes from finishing a thick book.However，ebook devices (设备) are easy to carry. 4_B_A disa

22、dvantage of e-book devices is that people tend to get distracted (分心) when theyre using one, as many devices often have apps or games on them. 5_F_Whichever you prefer, both books and e-books are just a way to help us gain knowledge and get to know other peoples experiences.They are both necessary,

23、so its too early to say one will disappear.ABut they have differences as well.BThey take less space than books.CIndeed our lives are formed by what books we read.DThis is similar to how the words in books manage to live on.EThey all have an index to introduce the main topic of each book.FBut with a

24、regular book, your mind is always absorbed in the words.GEach individual can decide which reading method is best for them based on their own needs.文章大意：本文是一篇说明文。介绍了常规书和电子书各有各的优点和缺点，它们是帮助我们获取知识的两种工具，现在说谁被谁取代还为时尚早。解析：1根据本空前的“Castles (城堡) and temples wear away after hundreds of years, but the symbols a

25、nd words on the stone often survive.”可知，数百年之后，城堡和寺庙会磨损，但是符号和石头上的文字往往会幸存下来，此处需要一个承上启下的过渡句，既与前面提到的情况相关联，又要引出下文常规书和电子书的比较这个话题。故D项(这类似于书中的单词是如何生存下去的。)符合语境。2根据本空前的“Books and ebooks share lots of similarities.They are both items created by great minds.”可知，常规书和电子书的一个相似之处是它们都是由伟大的思想创造出来的，此处介绍另一个相似之处。故E项(它们都

26、有一个索引来介绍每本书的主题。)符合语境。3根据本空后的“Firstly, books dont have to be charged, while ebooks need electricity if we want to read them.”可知，常规书不需要充电，而电子书需要充电，由此可知本段讲的是常规书和电子书的不同之处。故A项(但是，它们也有不同之处。)符合语境。4根据本空前的“However，ebook devices (设备) are easy to carry.”可知，电子书更方便携带，此处承接上文，说的是电子书的另一个优点。故B项(它们比常规书占用空间更少。)符合语境。5根

27、据本空前的“A disadvantage of ebook devices is that people tend to get distracted (分心) when theyre using one, as many devices often have apps or games on them.”可知，电子设备上的一些游戏和app很容易让人分心，此处讲的是常规书与之相比的优点。故F项(但是对于一本常规的书，你的思绪总是沉浸在文字中。)符合语境。.语法填空阅读下面材料，在空白处填入一个适当的单词或括号内单词的正确形式。The computer is widely used in our

28、 daily life.The computer is a machine that 1_was designed_(design) to help people do many things.When it first came into 2_being_(be), it was just a calculating machine, and later it was built as an analytical machine that could “think” logically and produce an answer 3_faster_(fast) than any other

29、person.Still later, the computer could be made to work as a “universal machine” to solve any difficult mathematical problems.There were times when its size was 4_totally_(total) changed.It became smaller and smaller but it got cleverer and cleverer.In the early 1960s, computers were connected by net

30、work and brought into common peoples homes 5_to deal_(deal) with information and help communication 6_between_ people around the world.It could share 7_information_(inform) with others and they could talk to each other.The Internet has become 8_an_ important part in our life and we can do many thing

31、s with the help of the Internet.The computer is used to connect people 9_who/that_ arent close enough to speak to each other.It has been serving the human race since 10_its_(it) birth.文章大意：本文是一篇说明文。文章介绍了计算机的发展历史。解析：1考查时态和语态。that _1_ (design) to help people do many things是一个定语从句，先行词是a machine，a machi

32、ne与design之间是被动关系，用被动语态，表示发生在过去的事情，用一般过去时。所以填was designed。2考查固定短语。句意：当它刚出现的时候，它只是一台计算机。come into being“产生”，该短语是固定短语。所以填being。3考查比较级。根据than any other person可知用比较级。所以填faster。4考查副词。该空修饰动词changed，用副词。所以填totally。5考查非谓语动词。句意：在20世纪60年代早期，计算机通过网络连接起来，并被带进普通人的家里来处理信息，帮助世界各地的人们进行交流。作目的状语，用不定式。所以填to deal。6考查介词。

33、句意：在20世纪60年代早期，计算机通过网络连接起来，并被带进普通人的家里来处理信息，帮助世界各地的人们进行交流。文中表示“在之间”。所以填between。7考查名词。句意：它可以与他人分享信息，他们可以互相交谈。该空作share的宾语，用名词。所以填information。8考查冠词。句意：互联网已经成为我们生活中一个重要的部分，在互联网的帮助下，我们可以做很多事情。文中泛指“一个重要的部分”，important的首字母发音是元音。所以填不定冠词an。9考查定语从句。_9_ arent close enough to speak to each other是一个定语从句，先行词是people，关系词在从句中作主语，指人。所以填who/that。10考查代词。句意：它自诞生以来就一直在为人类服务。文中表示“它的诞生”，用形容词性物主代词。所以填its。
