      Passage One

      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。

      Questions 46 to 50 are based on the following passage。

      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。

      The brain ages just like the rest of the body。 Certain parts shrink, especially areas in the brain that are important to learning, memory and planning。 Changes in brain cells can affect communication between different regions of the brain。 And blood flow can be reduced as blood vessels narrow。

      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。

      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。

      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。

      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。

      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。

      题干关键词为memory slips,slip意思为小错误,可一定到原来的小说第一段第二句和第三句。结合题干和原作可见,记念的小错误不要全部都以脊椎结核的病症,而可能是出于年纪大。题干中symptoms意为症状和最先的小说中的signs为一样替换。

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

      47.C) Communication within our brain weakens

      深入分析:找到关键词 memory slips。对应到作品第一段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。结合题干和原来的书文可见,回想的小错误不要全部都是愚钝的病症,而大概是由于年龄大。symptoms和signs为同一替换。顾答案选取A。

      题干意思为随着年纪增大,将会生出哪些变化。根据出题顺序,第二段尚未涉及变化,第三段第三句有changes,意思为,头脑细胞的变动会耳熟能详大脑不相同区域间的关联。此和C选项为同样替换,C选项题干意思为大脑内部的关系会减少。

      47。 C Communication within our brain weakens。

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

      剖析:依照各样原则对应文章定位句是Changes in brain cells can affect communication between different regions of the brain。 答案与定位句同义,顾答案C。

      题干意思为哪部分症状应该被认真对照。关键词为symptoms和take seriously。第四段有far more concerning,意为严正关注,可见答案在第五段。本段列举了多少个例证,三个是忘记了一部分常常的事物比方烤箱的操作,一个是忘记了哪些驾车去老友家。题干A意思为完全忘记了什么样去操作平常的有个别例行公事。符合例子的特征。因而选A。

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

      49.A) Check the brain’s cognitive reserve

      分析:题干关键词,memory-related symptom以及take seriously。定位到But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says。关键点在far more concerning故答案选取A。

      题干意思为,当严重的回忆衰退出现的时候,应该做什么?可一定到第6段最终一句“defense against memory …by building up your brain’s cognitive reserve。”符合A选项描述。

      49。 A Check the brain’s cognitive reserve。

      50。 D) Staying active both physically and mentally

      深入分析:题干关键词为signs of memory loss。定位到尾数第二段率先句话Defense against memory loss is to try to prevent it by building up your brain’s cognitive (认识的) reserve, Daffner says。故答案为A。

      据advice可定位到最一段。依据最后两句话可见既有头脑的也会有体力的建议。符合D选项的描述。

      50。 D Staying active both physically and mentally。

      来源:新东方

      分析:题干关键词Dr Daffner’s advice ,memory loss。定位到文章最终一句。Dr Daffner’s adviceIn other words, keep your brain busy and working。 And also get physically active, because exercise is a known brain booster。
