限制性定语从句，修饰指人的先行词students，并在从句中作主语，应用who引导该从句。4.tocome考查非谓语动词。asksb.todosth.为固定搭配，意为“让某人做某事”，故填tocome。5.secretly考查词性转

之间无连词连接，应用非谓语动词形式。measure与主语Theresearchers之间为逻辑上的主动关系，应用现在分词形式作伴随状语，故填measuring。8.results考查名词的单复数。result意为“结果”，为可数名词，根据下文中的介

绍可知，此处指不止一个结果，应用复数形式。9.than考查介词。根据句意和句中的less可知，此处表示比较意义，故填than。10.affects考查动词的时态和主谓一致。分析句子结构可知，设空处在从句中作谓语，从句主语为动名词短语usingphonesinpublic，为单数概

sy)itwillbecome.【语篇解读】本文是一篇说明文。在公开场合我们都会恐惧讲话，本文作者分享了克服演讲恐惧的经验。1.isranked考查动词的时态和语态。本句的主语是thefearofspeaking，与谓语rank之间是被动关系，根据上下文可知，应使用一般

现在时。故填isranked。2.death考查名词。thefearof后跟名词，die是动词，其名词形式为death。故填death。3.if考查连词。句意：对很多人来说，这可能听起来有点极端，但如果你一想到要在众人面前讲话就紧张得拼命冒汗的话，那么你可能知

道这种恐惧是可以理解的。根据句意可知，本句应用if引导条件状语从句。故填if。4.walked考查动词的时态。句意：我记得我曾经害怕公开演讲。当我走到观众前面时，我的腿就会发软。根据句意可知，讲述的是过去的事情，应

用一般过去时。故填walked。5.smiling考查非谓语动词。设空后的face是名词，应用形容词修饰，因此应用所给动词的现在分词形式作定语。故填smiling。6.the考查冠词。thewholespeech指的是整个演讲。故填th

e。7.exactly考查副词。分析句子结构可知，设空处修饰形容词good，应用副词形式。故填exactly。8.by考查介词。句意：你可以通过参加这样的俱乐部来做这件事。根据句意及空格后面的joining可知，此处应用介词。故填by。9.todo考查非谓语动词。volunt

eertodosth.“自愿做某事”。故填todo。10.easier考查形容词的比较级。“the＋比较级，the＋比较级”表示“„„越„„，„„就越„„”。故填easier。Ⅱ.根据提示补全句子1.促使她成功的原因，与其说是她的聪明，倒不如说是她的努力工作。(more...than...)

basicallytheageatwhichyourbodyfunctionsasitcomparestoaveragefitnessorhealthlevels”可知，生物年龄取决于我们的身体与同龄人相比有多好。故选D。2.D推理判断题。根据第二

段中的“Inthefuture,withadvancesinourabilitytocontrolbiologicalage,wemayhaveevenfewercandlesonourbirthdaycakethanthepreviousone．”和常识可知，过生日插生日蜡烛指的是生理

年龄的增长，由此判断出，第二段画线部分是指我们的生理年龄可能比前一年年轻。故选D。3.B推理判断题。根据第五段中的“Shewassurprisedbytheresults.”和“ButIdidnotfindmyresultstobeasgoodas

Ihadhopedtheywouldbe.”可推知，作者通过Levine的例子告诉我们这个算法可以揭示我们潜在的健康问题。故选B。4.D标题归纳题。通读全文以及第二段中的“Chronologicalageisn'thowoldwereallyare.It

'smerelyanumber”和“Weallagebiologicallyatdifferentratesaccordingtoourgenes,whatweeat,howmuchweexercise,andwhatenvironmentwelivein.”可知，我们的生理年龄可能会因为

我们的基因、饮食、运动量以及所处的环境不同而落后于或者超过实际年龄。故选D。Ⅱ.应用文写作(2020·湖北黄冈模拟)假定你是李华，你班交换生Jim将要参加“学在中国”留学生汉语演讲比赛，发邮件向你咨询。请你用英语给他回复一封邮件，内容包括：1.推荐一个演讲话题；2.说
