Ablogpostaboutonlinesafety同步练习参考答案一、阅读七选五1.A文章后面说theycanexpecttolivesixorsevenyearsmorethanmen．她们比男人可以多活六到七年，可以推测前面应该讲的是女人。故选A。2.G文章前一句说Oneimportantbiologicalfactorthathelpswomenlivelongeristhedifferenceinhormonesbetweenmenandwomen．男女荷尔蒙不同；后一句说womenproducehormonesthatareinvolvedinfertility女性的荷尔蒙与生育有关，可以知道这里讲的应该是荷尔蒙的问题。故选G。3.D前面说到Thesehormonesalsohaveapositiveeffectontheheartandbloodflow.荷尔蒙对心脏和血液有好处；后面说Theyhelpthebodydefenditselfagainstsomekindsofinfections.它们还可以对抗感染，可以推测这里讲的应该是荷尔蒙保护身体的另外一种方式。故选D。4.C后面一句是Scientistsarestillnotexactlysurehowgenesinfluenceaging科学家们还不清楚基因是如何对抗衰老的，可以知道前面应该说的是基因。故选C。5.E文章最后说Somethinkthatawoman’sbodycellshaveatendency（向）toagemoreslowlythanaman’s.Othersthinkthataman’sbodycellshaveatendencytoagemorequickly.女性身体细胞老化得比男人慢，或者说男人的细胞必女人老化得快。这两种可能性都得到了目前研究的支持，故选E。二、短文改错1.Your→My根据下文都在讲述的I的故事，故将your改为my。2.will后加bewill后跟动词原形，句子的主语是admit的动作承受者，故在will后加be。3.去掉willafter引导的时间状语从句，用一般现在时代替将来时，故去掉will。4.hoped→hope根据上下文都是一般现在时，此处也应一般现在时，故将hoped改为hope。5.whom→who/thatthose的定语从句中引导词应做主语，故将whom改为who/that。6.happy→happily此处应用副词修饰动词live，故将happy改为happily。7.exercises→exercise此处的exercise为不可数名词，故将exercises改为exercise。8.to→on根据短语focus...on...将……集中于……，故将to改为on。9.or→and根据该词前后的关系应是并列关系，故将or改为and。10.preparing→preparedbepreparedfor为……准备好，故将preparing改为prepared三、写作参考范文：Aheateddiscussionaboutwhetherthetakeoutshouldbepermittedinourschoolisheldamongusstudents.Asforsomestudents,thetakeoutisconvenientandtasty.Besides,theycangetwhattheywantinashorttime.However,somestudentsholdthebeliefthatthetakeoutpackedintheplasticbagsisunsafetoeatbecausetheplasticbagsathightemperaturecandoharmtoourhealth.Moreover,
