unit 4body language.阅读理解a2019贵阳市期末检测you try to keep your eyes wide open while watching a basketball match or a wonderful firework show in case you might miss something exciting in just the blink of an eye. but in fact, humans blink about 15 times per minute on average. have you ever missed anything because you blinked? probably not. why is that?according to a new study published in the journal current biology in september, our brain has the ability to skip the temporary darkness when we blink. it can keep visual information for a short period of time and then put it together to form an image without interruption.in order to understand how this works, a group of scientists at the german primate center and the university medical center gttingen in germany conducted an experiment. in the study, the participants were asked to look at patterns on a screen whose direction could be interpreted in different ways, such as horizontally(水平地) or vertically(垂直地). when one pattern was about to disappear and the next one was about to come, the participants had to indicate the direction that the next pattern would appear.the researchers found that when the directions of two patterns didnt match, the area in our brain which is responsible for visual memory was activated. this same area showed less activity when two patterns were in the same direction.“the medial prefrontal cortex (额叶皮层) adjusts current visual information with previously obtained information, and thus enables us to perceive the world with more stability, even when we briefly close our eyes to blink，” caspar schwiedrzik explained in science daily. he is the first author of the study and also a scientist at the german primate center.1we dont miss anything when blinking because our brain can _.adeal with

inspired by a toy.in 1792, it started off as a twowheeled part attached to a rigid wooden frame. people would use their feet to move the bike. however, it wasnt really what people were looking for with a lot of faults. it was a kind of transport highly demanding human energy, and the other problem was the poor stability. the front wheel could not turn so one had to get off the bike to turn it. therefore，there was a need for it to be improved, but it was not the same person who created it that changed it.in 1820 the bike yet again had a new twist. not only could the front wheel turn，but it was made more comfortable as a back supporter was secured. but one still had to move it by pushing it by feet on the ground. if one wanted to ride this bike, which was called a “hobby horse” at that time, he should know how to keep his balance. the other impressive thing that had changed was the speed，which increased up to 15 kilometers per hour.ten years later, there came the bike popular even today. this was invented by a blacksmith who used the idea of a pivot(枢轴) to develop the bike. it did not stop there. people were never satisfied with it because times also did change. as other things were being improved, so were the bikes.now with everything in place, there is a need to improve on the speed of these bikes. and the idea of it being only humanpowered is out of date. today bikes have been improved and remodeled but the resemblance to the original bikes is still there.5what was one of the problems with the first bicycle?ait was regarded as a toy.bit had too many wheels.cit had to be operated with efforts.dit was too stable to turn the wheel.6what can we know about the bike from the text?athe bike popular with us today appeared in about1830.bthe bike was invented and improved

might miss something exciting in just the blink of an eye.分析：该句为主从复合句，句中“while watching a basketball match or a wonderful firework show”为while引导的时间状语从句，其中省略了you are；“in case you might miss something exciting in just the blink of an eye”为in case引导的条件状语从句。译文：在观看篮球比赛或精彩的烟花表演时，你努力睁大眼睛，以防转眼之间错过一些令人兴奋的事情。1a考查推理判断。根据第二段第一句“according to a new study published in the journal current biology in september, our brain has the ability to skip the temporary darkness when we blink.”可知，根据九月份发表在当代生物学杂志上的一项新研究，我们的大脑有能力跳过我们眨眼时形成的暂时黑暗。据此可推知，由于我们的大脑能处理丢失的图像，所以眨眼不会让我们错过任何东西，故a项正确。2b考查代词指代。根据第二段第二句“it can keep visual information for a short period of time and then put it together to form an image without interruption”可知，大脑可以在短时间内保存视觉信息，然后将其组合在一起形成不中断的图像。故可推知，it指代上文中的“visual information”，故b项正确。3d考查细节理解。根据第四段中的“when the directions of two patterns didnt match, the area in our brain which is responsible for visual memory was activated. this same area showed less activity when two patterns were in the same direction”可知，当两个模式的方向不一致时，则掌握视觉记忆的大脑区域被激活；当两种模式在同一个方向时，则这个区域显示出较少的活动。据此可知，不同的方向能激活视觉记忆，故d项正确。4c考查主旨大意。通读全文可知，本文主要介绍了一个科学研究。研究表明，眨眼不会错过细节并解释了其原因，即大脑有能力在短时间内保存视觉信息，然后将其组合在一起形成不中断的图像信息。故c项最适合作本文的标题。b体裁：说明文题材：社会生活主题：自行车的发展【语篇解读】本文主要介绍了自行车的历史发展过程及现状。【高级句式】not only could the front wheel turn, but it was made more comfortable as a back supporter was secured.(para. 3)5c考查细节理解。根据第二段中的“people would use their feet to move the bike”和“it was a kind of transport highly demanding human energy”可知，最初的自行车需要费很大的力气才能使它运转，故选c。6a考查细节理解。根据第三段第一句“in 1820 the bike yet again had a new twist”和第四段第一句“ten years later, there came the bike popular even today”可知，至今仍受欢迎的自行车大约出现于1830年。7a考查细节理解。根据第五段最后一句“today bikes have been improved and remodeled but the resemblance to the original bikes is still there”可知，现在的自行车和历史上的自行车在结构上仍然相似。8a考查主旨大意。根据全文内容，尤其是文中的“the idea of making a bike started in 1790s”“in 1792”“in 1820”“ten years later”“today”等信息点可知，这篇文章主要介绍了自行车的历史发展过程。分析：本句含有“not only. but(also).”句型，意为“不但而且”，其中not only置于句首，其所属的分句要部分倒装。.完形填空体裁：记叙文题材：个人经历主题：关心失去亲人的熟人【语篇解读】本文是一篇记叙文，主要讲述了作者在失去亲人后心理状态很不好，由于受到了别人的帮助而恢复了正常之后，她也以同样的方式帮助失去亲人的熟人。1c根据空前的“i stumbled (跌跌撞撞地走)”和下文中的“i tried to hold my tears”以及文章开头第一句话可推知，作者听到亲人去世的噩耗时，有些不知所措，虽然是在收拾行李。却不知道该把什么放进手提箱里。wonder“感到疑惑，想知道”。2b根据本句中的“for moving to new mexico”可推知，作者为搬家到新墨西哥州而打包(packing)。3d根据上文可知，作者和丈夫一直在为搬家而收拾行李，由此可推知，当时作者的家里应该是很杂乱(mess)。4a根据上句“i tried to hold my tears”和本句中的“picked things up and put them down”可推知，作者因为听到弟弟去世的噩耗而悲伤不已，乱了方寸。aimlessly“无目的地，无计划地”符合语境。5c根据语境可知，作者当时的心理状态非常不好，不能集中精力做事情。focus“集中(注意力、精力于)”符合语境。6a根据上句“larry phoned a few friends”可推知，作者的丈夫将作者失去弟弟的事情告诉了一些朋友，他们接着就不断地(constantly)打电话说愿意提供帮助。7b根据语境可知，作者当时并不知道需要朋友们提供什么样的帮助。call for“呼吁”；ask for“要求，请求”；talk about“谈论”；get across“解释清楚”。8d根据本句中的“the doorbell rang”可知，作者站起来去应门(door)。9c根据下文中的“to get the shoes cleaned”可推知，donna是来帮作者清理(clean)鞋的。10c根据本句中的“i asked her to repeat”可推知，作者当时对donna说的来帮她清理鞋子感到困惑(confused)。touched“受感动的”；shocked“震惊的”；amused“逗乐的”。11b根据本句中的“when my father died”和“to get the shoes cleaned and _12_ for my fathers _13_”可推知，donna应是说她为了参加父亲的葬礼(funeral)去清理鞋子并把它们擦亮(shined)。12d参见上题解析。13b参见第11题解析。14d根据上句“shoes were gathered”和语境可推知，当鞋被聚集到一起之后，donna在地板上找到舒适的位置(settled)开始清理鞋。15a根据上文中的“i tried to hold my tears”和语境可知，donna用行动所展示的关爱让作者感动得流泪。release“释放”。16b根据上文“donna _14_ herself on the floor and got to work”可知，当时donna在专心地清理鞋。keep on“继续；反复做”；concentrate on“集中(注意力)于”；insist on“坚持”；depend on“依靠”。17a根据上文可知，作者当时因为亲人的突然离世而乱了思绪，而看到donna专心地帮她清理鞋让她的思想(thoughts)恢复到了有序状态。18c由上文提到作者的弟弟突然离世可知，此处表示每当“我”听说熟人的亲人去世(loss)。19a根据上文中的“watching her _16_ on one task”可知，“我”会想一件能满足那个失去亲人的熟人需要(need)的具体的(specific)工作。20d参见上题解析。.短文改错one year ago, i was in great trouble. i worked hard at english and devot all my spare time to practis it. but i failed to pass the
