  D) They are quite common among fifty-year-olds。

  Questions 46 to 50 are based on the following passage。

  A) Not all of them are symptoms of dementia。

  50。 D) Staying active both physically and mentally

  B) Some parts of our brain stop functioning。

  C) Engaging in known memory repair activities。

  Losing your ability to think and remember is pretty scary。 We know the risk of dementia (痴呆) increases with age。 But if you have memory slips, you probably needn’t worry。 There are pretty clear differences between signs of dementia and age-related memory loss。

  47.C) Communication within our brain weakens

  C) Communication within our brain weakens。

  B) Inability to recall details of one’s life experiences。

  题干意思为随着年龄增大,将会发生什么变化。根据出题顺序,第二段没有提到变化,第三段第三句有changes,意思为,脑细胞的变化会影响大脑不同区域间的沟通。此和C选项为同义替换,C选项题干意思为大脑内部的沟通会弱化。

  49。 What should people do when signs of serious memory loss show up?

  C) Stop medications affecting memory。 D) Exercise to improve their well-being。

  But even then, Daffner says, people shouldn’t panic.There are many things that can cause confusion and memory loss, including health problems like temporary stoppage of breathing, high blood pressure, or depression, as well as medications like antidepressants。 Even over-the-counter remedies like antihistamines can contribute to memory loss。

  题干意思为,当严重的记忆衰退出现的时候,应该做什么?可定位到第6段最后一句“defense against memory …by building up your brain’s cognitive reserve。”符合A选项描述。

  A) Our interaction skills deteriorate。

  2018年上半年全国大学英语四六级考试于6月16日进行,新浪教育24小时全程关注,为你带来第一手四六级考试资讯。以下为英语四级阅读详解:

  A) Check the brain’s cognitive reserve。 C) Turn to a professional for assistance。

  48。 Which memory-related symptom should people take seriously?

  Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about。 But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says。

  49.A) Check the brain’s cognitive reserve

  B) They occur only among certain groups of people。

  据advice可定位到最一段。根据最后两句话可知既有脑力的也有体力的建议。符合D选项的描述。

  C) Not all of them are related to one’s age。

  After age 50, it’s quite common to have trouble remembering the names of people, places and thing quickly, says Dr。 Kirk Daffner of Brigham and Woman’s Hospital in Boston。

  48。 A)Totally forgetting how to do one’s daily routines

  And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive (认知的) reserve, Daffner says。

  “Read books, go to movies, take on new hobbies or activities that force one to think in novel ways,” he says。 In other words, keep your brain busy and working。 And also get physically active, because exercise is a known brain booster。

  D) Occasionally confusing the addresses of one’s friends。

  50。 What is Dr Daffner’s advice for combating memory loss?

  47。 What happens as we become aged according to the passage?

  46。 Why does the author say that one needn’t be concerned about memory slips?

  题干意思为哪一些症状应该被认真对待。关键词为symptoms和take seriously。第四段有far more concerning,意为严正关切,可知答案在第五段。本段列举了两个例子,一个是忘记了一些日常的东西比如烤箱的操作,一个是忘记了如何开车去老友家。题干A意思为完全忘记了如何去操作平常的一些例行公事。符合例子的特点。因此选A。

  A) Totally forgetting how to do one’s daily routines。

  D) Staying active both physically and mentally。

  46。 A) Not all of them are symptoms of dementia

  B) Taking medicine that helps boost one’s brain。

  题干关键词为memory slips,slip意思为小错误,可定位到原文第一段第二句和第三句。结合题干和原文可知,记忆的小错误并非全是痴呆的症状,而可能是由于年龄大。题干中symptoms意为症状和原文中的signs为同义替换。

  When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved。” Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong。

  D) Our whole brain starts shrinking。

  A) Having regular physical and mental checkups。

  C) Failure to remember the names of movies or actors。
