C8.A【解析】段落大意题。第二段主要讲述游泳的起源可以追溯到7000年前,所以答案为A。9.B【解析】推理判断题。第三段的内容主要介绍欧洲国家的游泳发展,特别是英国的游泳。根据“Englandisbelievedtobethefirstmodernsocietytoconsiderswimmingasasport.”可知,英国游泳的发展对游泳被纳入奥运会起了促进作用。10.C【解析】推理判断题。根据最后一段Coubertin的观点和1912年女子游泳才被纳入奥运会的史实可知。11.B【解析】词义猜测题。根据上文,在1896年奥运会上没有女子游泳比赛,因为Coubertin认为游泳需要力气,女子不是很强壮,所以没有把女子游泳纳入,答案为B。D12.B【解析】细节理解题。根据第一段中的DrCameronissurethatthisallowspeoplewhoexercisetohaveaclearerandmoreactivemind.可知，身体上的锻炼有助于更清晰更敏捷地思考。13.D【解析】推理判断题。根据第二段第二句Babieswhodoactivitiesthatrequirealotofmovementandphysicalactivityshowgreaterbraindevelopmentthanbabieswhoarelessphysicallyactive.可知，婴儿做的活动越多，他们的大脑发育得就越好。14.C【解析】细节理解题。根据文章最后一段中的exerciseforolderpeopleshouldnotbetoosimple.Learningsomenewskillsoractions,suchaswithyoga.可知，瑜伽可以防止老年人健身动作过于简单，稍复杂的动作有助于脑部记忆，故选C项。15.A【解析】细节理解题。根据最后一段最后一句Andyourbraincanbenefitfromaslittleastwotothreehoursofexerciseaweek.可知健脑时间每周应至少2～3小时。第二节（共5小题：每小题2.5分,满分12.5分）16.G【解析】根据空格上文可知，学习时间长并不意味着学得更好，因此推断空格处选G项“为了充分利用时间，你需要学会如何高效地学习”符合语境。17.C【解析】本段作者建议寻找一个合适的学习地方。空格上文阐述第一件事就是要避开学习时分散注意力的事物，因此推断C项“这意味着要去一个能够让你感到宁静的地方”符合语境。18.F【解析】本段作者建议把任务分解来完成。空格下文阐述通过这样做，你能够更容易地知道每一个主题需要多长时间。因此推断空格处选F项“如果你有一个大的项目，你需要把它分解成较小的部分”符合语境。19.A【解析】本段作者建议安排好学习中的休息时间。根据空格上下文可知，你应当安排好学习时的休息时间，这样可以使你的眼睛得到休息，有机会去卫生间或者喝杯咖啡。因此推断空格处选A项“每两个小时休息15分钟”符合语境。20.B【解析】本段作者建议按照重要性为你的任务排序，空格下文阐述如果你认为你没有足够的时间完成所有的科目，你应当有序的学习，以防你用光学习时间。因此推断空格处选B项“学会按照重要性安排科目”符合语境。第二部分语言运用（共两节，满分30分）第一节（共15小题：每小题1分，满分15分）A【解析】根据下文EventhoughIknewthiswascertainlynotmyfirstmistakeinlife...内容可知，此处是指犯错误。22.D【解析】根据空前Duringeachmathclass可知，此处是指“我”在课堂上听课。23.B【解析】根据空后内容可知，此处是指问题。24.C【解析】根据空后的Answeringthem可知，此处是指举手回答问题。25.D【解析】根据空后的feelIwasrecognized可知，此处是指回答正确。26.B【解析】根据空后内容可知，此处是指要达到每次都正确的标准是不可能的。27.A【解析】根据第28空前的myfirstmistake可知，此处是“我”给了一个错误的答案。28.C【解析】根据下文“我”的转变可知，此处是指在那刻不一样的事情发生了。29.D【解析】因为“我”的错误回答，所以“我”认为别的同学会觉得“我”是愚蠢的，心中建立的美丽城堡也在犯错后倒塌了。30.B【解析】根据下文内容可知，从此“我”情绪低落，也不愿意再冒险回答问题。31.D【解析】根据“我”的表现可知，此处是指反常。32.C【解析】错误是学习的重要部分，因为错误可以帮助指出我们的缺点并帮助我们进步，此处是指原因。33.A【解析】因为错误的这些作用，所以“我”应该在学习中接
