具。l8.E。此空设于段首,是本段的总起句。根据下文The exact number varies可知,本句作为本段的总起句,介绍了轮胎上小毛刺数量是不固定的。19.F。此空设于段尾,与上文存在递进关系。上文介绍了轮胎上的小毛刺对安全驾驶没有影响,本句进一步说明:它们仅仅是新轮胎问世的证据。20.G。此空设于段中,与上文存在转折关系。上文提到轮胎上小毛刺的存在与否并不能决定轮胎是否安全。然而,在一种情况下,轮胎毛刺的缺乏可能很重要:这可能是轮胎磨损、陈旧并且需要更换的迹象。完形填空导语:本文是一篇夹叙夹议文,属于“人与社会”主题语境。作者对于标点符号的使用有着自己的偏好,也会认真使用标点以示在乎,文章提醒人们在微交际中谨慎使用标点符号。2l.C。根据..when to move fast or stop可知,标点的存在为文章设定了节奏。22.B。根据I use fewer commas..及第二段中的but I use a long dash instead可知,在标点的使用方面,作者有着自己的偏好。23.A。根据上文的.a huge fan of the semicolon及下文的Dad often uses so many semicolons可知,作者的父亲总是忍不住使用分号。24.D。根据下文的The dash is a gentle.The semicolon marks.可知,作者认为分号和破折号的作用一致,但给人的感觉不同。25.B。根据下文的whose writings.19th-century novel可知,此处指使用分号的作者是老派的人。26.C。根据语境可知,此处指读那些喜欢用分号的作者的作品,就如同在赏读19世纪的小说一样。27.B。根据19th-century novel及Just a few paragraphs.heavy eyelids..可知,大量的分号使父亲信件的节奏沉闷、乏味。28.D。根据语境可知,仅仅几段过后,作者感到昏昏欲睡,不得不和沉重的眼皮抗争。29.A。根据语境可知,此处表达当作者给他人发信息时该如何使用标点。30.A。根据上一句及下文的not an effortless task可知,作者发信息时,会考虑哪里用大写、怎么加标点,这是麻烦费心之事。31.D。根据语境可知,尽管如此麻烦,但作者依然这么做,他不想让人觉得自己不在乎。32.C。根据语境可知,作者理解了有些人不愿在标点上受麻烦,毕竟,这不是一件毫不费力的事情。33.B。上文提及一个问题,一个回答,此处表达提问者得到了自己想要的信息。34.C。根据上文描述的场景可知,这里表达她一定不会去,表达一种强烈的语气。35.D。根据语境可知,你的消息似乎惹恼了她,因此她才那样回复。语法填空导语:本文是一篇说明文,属于“人与社会”主题语境。简要介绍了中国的非遗diabolo(空竹)及两位传承人和中国国家杂技团为了弘扬空竹艺术所做出的努力。36.is cast。.考查动词的时态和语态。根据句意可知,这里陈述的是空竹的玩法,属于客观描述,谓语动词用一般现在时;主语是it,且与cast是被动关系,故用is cast。37.o。考查介词。根据句意可知,这里表达的是“这些流畅的动作吸引了所有的人”,要用appeal to,故填to。38.musical.。考查形容词。根据句意可知,这里需要一个形容词作sound的表语,故用musical.。39.a。考查不定冠词。这里native是单数名词,意为“本地人”,且以元音音素开头,这里表泛指,故用不定冠词a。

A导语:本文是一篇说明文,属于“人与社会”主题语境。文章介绍了四个大学研究项目。2l.B。理解具体信息。根据Program A部分的UCL doctoral students have the opportunity toconduct research at Yale University..可知,该项目是两所大学之间的交流。22.B。理解具体信息。根据Program B部分的Students should apply for the program early tosecure places in preferred projects.可知,学生需尽早提交申请。23.A。推断。根据Program C和Program D的Dates部分提供的信息可知,这两个项目的共同点在于有灵活的时间安排。B导语:本文是一篇夹叙夹议文,属于“人与自我”主题语境。作者以自身经历举例说明内向并没有错,不会影响一个人今后的发展。24.D。推断。根据第一段最后一句可知,朋友的话让作者感到困扰是因为大部分人认为拥有一个害羞的孩子是一件非常负面的事情,这反映了人们对害羞孩子的偏见。25.B。理解具体信息。根据第二段And no matter what anyone else says,I'm okay with that.可知,无论作者的女儿是什么样的性格,作者都乐于接受。26.C。推断。根据第三段Growing up as a shy.come out of my shell.可知,作者通过讲述自己小时候大人帮助她克服害羞的性格,却让情况变得更糟的经历表明了成年人以错误的方式帮助害羞的孩子。27.D。理解具体信息。根据最后一段Shyness doesn't always hold people back.可知,害羞对人们以后的发展并没有多大的影响,她并不认同害羞的负面影响。C导语:本文是一篇说明文,属于“人与自然”主题语境。文章主要介绍了路氏双髻鲨在深海中捕食猎物时有效保持体温的方法。28.A。理解词汇。根据第二段划线单词前后的句子可知,极端的温度下降会削弱鲨鱼的视力和大脑功能,并导致鲨鱼的肌肉僵硬,使得鲨鱼无法前进并将富含氧的水推入其鳃中,这对鲨鱼来说是生死攸关的,因此可推断划线单词意为“致命的”。29.C。推断。根据第三段的To figure it out.attached a pack of sensors.These included aspecial instrument及第四段的The data showed可知,研究者给鲨鱼身上安装了一套传感器收集数据,然后分析这些数据得到了研究结果。30.C。理解具体信息。根据第四段the sharks...body temperature within0.1 Cfor the entirety oftheir dive..the surface.可知,在整个潜水的过程中,鲨鱼的体温只略微变化0.1C,因此可知,鲨鱼在深海潜水中保持稳的体温。3l.B。推断。根据第五段hammerhead sharks close their gills.escaping into the ocean.Thisstrategy可知,鲨鱼深海潜水时,闭上了鳃和嘴,屏住呼吸,这种策略使得他们能够维持体温。D导语:本文是一篇说明文,属于“人与社会”主题语境。研究发现随着时间的推移早期学成绩不佳的学生可以“迎头赶上”。32.A。理解具体信息。根据第二段We examined reading and numeracy...areas of the curriculum可知,研究人员选择研究阅读和算术能力是因为它是很多其他学科的学基础,故能反映整体学能力的发展。33.B。理解具体信息。根据第三段we found thatstudents starting with below.with students starting above average可知,大部分低于均水的学生取得了更多的进步。
