排便，A正确；神经系统存在分级调节，脊髓中的低级中枢受到大脑中的高级中枢调控，因此感受到便意但能主动抑制排便的过程，B正确；某人受到创伤后导致没有便意，可能是排便反射弧中传入神经受损，使兴奋不能传到大脑皮层产生便意，C正确；成年人出现大便失禁不一定是损伤了大脑中的高级中枢，还可能是脊髓损伤导致的高位截瘫，D错误。3.A解析：S区为运动性语言中枢，损伤后，患者与讲话有关的肌肉和发声器官完全正常，能发出声音，但不能用词语表达思想，A错误；下丘脑是生物的节律中枢，损伤发生在下丘脑时，患者可能出现生物节律失调，B正确；损伤导致上肢不能运动时，可能是大脑皮层的躯体运动中枢受到损伤，此时患者的缩手反射仍可发生，因为缩手反射的低级中枢在脊髓，C正确；排尿的高级中枢在大脑皮层，低级中枢在脊髓，损伤发生在大脑时，患者可能会出现排尿不完全，D正确。【易错点拨】缩手反射、膝跳反射的中枢在脊髓，大脑皮层的躯体运动中枢受到损伤，这些反射仍然可以发生。4.A解析：大脑皮层对肢体运动的支配具有交叉性，右侧肢体偏瘫是由于大脑左侧半球受损引起的，而大多数人的语言中枢位于大脑左半球，所以右侧肢体偏瘫的患者常常伴有失语症，A正确。若患者可以看懂文字，能理解别人说的话，但是不能用语言表达思想，则为运动性失语症；若患者能说话，也能听到别人说话，但是听不懂别人说话的内容，则为听觉性失语症，B错误。健康人大脑皮层的语言中枢，其各功能分区并不是孤立存在的，而是相互有密切的联系，C错误。语言活动是人类特有的，是区别于其他动物的显著特征之一，D错误。【归纳总结】大脑皮层对肢体运动的支配具有交叉性，表现为左右颠倒，上下颠倒。5.D解析：根据题干信息可知，光照能够促进UCA大幅增加，UCA可进入大脑神经细胞内并转化成谷氨酸，A错误；根据分析可知，细胞内的谷氨酸能在海马区释放，可增强动物的短时记忆，可能为感觉性记忆或第一级记忆，B错误；学和记忆是脑的高级功能之一，是指神经系统不断地接受刺激，获得新的行为、惯和积累经验的过程，是条件反射的建立过程，不是由单一脑区控制的，而是由多个脑区和神经通路参与，C错误；根据题干信息可知，抑制谷氨酸的合成会减少谷氨酸在运动皮层以及海马区的神经末梢释放，导致运动学能力以及物体识别记忆能力下降，D正确。6.B解析：神经递质在突触间传递信息，突触可将电信号转变成化学信号再转变成电信号，A正确；5-羟色胺释放的方式是胞吐，从图可知5-羟色胺被回收要通过转运体的作用，是主动运输，B错误；由于SSRI药物能够抑制5-HT转运体的功能，抑制突触前膜对5-HT的回收，使5-HT作用时间延长，兴奋时间延长，所以服用SSRI药物可以缓解抑郁情绪的发生，C正确；积极建立和维系良好敖学笔记

employees,the thinking went,would create more interaction and teamwork,promote social interaction,and urgeproductivity.”可知，开放式办公空间趋势成为主流，是因为人们相信开放的空间环境支持创新。这种想法认为，员工之间的距离越近，就会产生更多的互动和协作，促进社会互动，并刺激生产力。29.答案D命题透析词义猜测题。思路点拨根据前面一句“Instead of talking more with each other,.the employees put on headphones and begancommunicating by text and email.”可知，员工们没有更多地相互交谈，而是戴上耳机，开始通过短信和电子邮件进行交流。由此推知，此句意为：随着数字通信渠道的激增，生产力下降了。30.答案D命题透析细节理解题。思路点拨根据第三段的“Even more troublesome are overheard‘halfversations',in which the listener only knowsabout one side of a dialogue;our brains automatically imagine the other'”可知，更具有a破坏性的是无意中听到的“半句话”，在这种情况下，听众只能听到对话的一部分；我们的大脑会自动想象其他内容。也就是说，听到同事间对话的一部分会影响开放式办公人员的工作效率。31.答案C命题透析推理判断题。思路点拨根据最后一段的“But the solution,say experts including Newport,isn't to go back to putting everyoneinto offices with walls..”可知，下文可能涉及的内容是应对开放式办公室缺点的解决方案。文章大意：本文是一篇说明文。研究人员发现通过在风力涡轮机的叶片和杆子上画上黑白条纹，可以减少因碰撞而死亡的鸟类的数量。32.答案D命题透析细节理解题。思路点拨根据第二段的“One of the main oppositions to such adoption is the fact that wind turbines often result inhigher rates of bird deaths as birds hit with the spinning blades,reducing populations of important species such aseagles and seabirds..”可知，反对采用这种方法的主要原因之一是，风力涡轮机对鸟类造成了威胁。33.答案B命题透析细节理解题。思路点拨根据第三段的“The design was to be high contrast,enabling it to be spotted even in low light,andwould create a‘flickering(闪烁)'effect when spinning,which birds are great at identifying.”可知，该设计是高对比度的，即使在弱光下也能被发现，并在旋转时产生“闪烁”的效果，而这正是鸟类最擅长识别的。34.答案A命题透析推理判断题。思路点拨根据最后一段的“It would,however,.be a tougher sell on residents,who already complain about thevisual pollution of large turbines.”可知，对于已经抱怨大型涡轮机的视觉污染的居民来说，这将是一个更艰难的销售。由此可推断，当地居民认为该设计不太好看。35.答案C命题透析标题归纳题。思路点拨通读文章可知，本文主要介绍研究人员发现通过在风力涡轮机的叶片和杆子上画上黑白条纹，可以减少因碰撞而死亡的鸟类的数量。36-40 CDEBG一4
