32.D。理解文章结构。文章开篇通过讲述作者自己常做的梦的场景来引入话题。33.A。理解具体信息。根据第三段中的To find out what my specific performance-based anxietydream means,I went to Jane Teresa Anderson...she told me,is "feeling tested in life,and notmeeting other people's expectations.So you think back to school..”可知，Anderson认为，作者感到自己在生活中被考验，未能达到别人的期望值，这导致他总是做同样的梦。34.C。理解具体信息。根据第四段中的The reason school dominates as a go-to anxiety setting,Anderson said,is that school is where we build our understanding of how life works可知，由于人们的价值观主要是在学校形成的，所以他们焦虑时做梦常梦到和学校有关的事情。35.A。理解具体信息。根据最后一段中的Stil,if you'd like to finally graduate from dream school,,Anderson has a method.Immediately post-dream.While you're lying in bed,imagine the dreamscenario again,but this time with a more relaxing outcome可知，Anderson建议人们做梦后自己想象一个好的梦的结局，以此来改变自己的心态。第二节主题语境：人与自我一一学本文是说明文。文章介绍了几种做笔记的技巧。36.C。根据设空处后的Students remember knowledge better when they generate materialsthemselves rather than having materials given to them可知，让学生自己“生成”材料比给他们材料更有助于他们记住知识，因此，C项“由于生成效应，记笔记可以增强学（效果）”符合语境。设空处后一句具体解释C项的内容。设空处后的they generate materials themselves与C项中的Taking notes相呼应，generate与C项中的generative构成原词复现。37.D。设空处与前后句构成顺序关系。设空处所在段主要谈了什么是Cornell Notes。Cornell格式有助于组织笔记，它一共分为四部分，设空处谈到的是第二部分一一笔记框架的左侧部分应该记录什么。38.E。设空处解释说明了用手机或者板录制讲座的益处。E项中的That way指代前一句中的record the lecture.39.G。设空处所在段主要谈了做笔记的过程中用彩笔做标记会使学生更喜欢复笔记。但前提是，要用自己喜欢、但又不让自己分心的颜色。G项中的you like呼应本段小标题中的fascinating,visual element指代colors。40.B。设空处所在段主要谈了在笔记中运用图画让自己的笔记更容易被记住。根据设空处后的But可知，前后两句是转折关系，设空处后谈了在话题旁画插画有助于自己记忆笔记内容，那么设空处应该和该观点相对，因此，B项“我不是小学生，为什么要画画？”符合语境。语言知识运用第一节主题语境：人与自我一一生活本文是记叙文。母亲给作者的生日礼物成为她日后的一种念想，并给她力量。41.C。根据下文的the sweet smel‖floated out as soon as I lifted the cover可知，作者的母亲用香水盒子装了送她的衬衣。42.B。根据上文的the fuchsia shirt可知，衬衣反映出作者的母亲喜欢成为人群中的焦点。43.A。和母亲的性格相反，作者行事低调。44.A。45.C。作者把衬衣叠好后又放回到盒子里，但是她没有告诉母亲，她可能永远不会穿那件衬衣。46.D。47.B。48.D。根据文中的the...of returning it to a store I rarely visited or being overtakenby everyday life可知，由于某种原因（去她很少去的商场太麻烦，或者每天事情太多），作者从未将衬衣退回商店。
