Ablogpostaboutonlinesafety同步練習(xí)參考答案一、閱讀七選五1.A文章后面說theycanexpecttolivesixorsevenyearsmorethanmen．她們比男人可以多活六到七年，可以推測前面應(yīng)該講的是女人。故選A。2.G文章前一句說Oneimportantbiologicalfactorthathelpswomenlivelongeristhedifferenceinhormonesbetweenmenandwomen．男女荷爾蒙不同；后一句說womenproducehormonesthatareinvolvedinfertility女性的荷爾蒙與生育有關(guān)，可以知道這里講的應(yīng)該是荷爾蒙的問題。故選G。3.D前面說到Thesehormonesalsohaveapositiveeffectontheheartandbloodflow.荷爾蒙對心臟和血液有好處；后面說Theyhelpthebodydefenditselfagainstsomekindsofinfections.它們還可以對抗感染，可以推測這里講的應(yīng)該是荷爾蒙保護(hù)身體的另外一種方式。故選D。4.C后面一句是Scientistsarestillnotexactlysurehowgenesinfluenceaging科學(xué)家們還不清楚基因是如何對抗衰老的，可以知道前面應(yīng)該說的是基因。故選C。5.E文章最后說Somethinkthatawoman’sbodycellshaveatendency（向）toagemoreslowlythanaman’s.Othersthinkthataman’sbodycellshaveatendencytoagemorequickly.女性身體細(xì)胞老化得比男人慢，或者說男人的細(xì)胞必女人老化得快。這兩種可能性都得到了目前研究的支持，故選E。二、短文改錯(cuò)1.Your→My根據(jù)下文都在講述的I的故事，故將your改為my。2.will后加bewill后跟動詞原形，句子的主語是admit的動作承受者，故在will后加be。3.去掉willafter引導(dǎo)的時(shí)間狀語從句，用一般現(xiàn)在時(shí)代替將來時(shí)，故去掉will。4.hoped→hope根據(jù)上下文都是一般現(xiàn)在時(shí)，此處也應(yīng)一般現(xiàn)在時(shí)，故將hoped改為hope。5.whom→who/thatthose的定語從句中引導(dǎo)詞應(yīng)做主語，故將whom改為who/that。6.happy→happily此處應(yīng)用副詞修飾動詞live，故將happy改為happily。7.exercises→exercise此處的exercise為不可數(shù)名詞，故將exercises改為exercise。8.to→on根據(jù)短語focus...on...將……集中于……，故將to改為on。9.or→and根據(jù)該詞前后的關(guān)系應(yīng)是并列關(guān)系，故將or改為and。10.preparing→preparedbepreparedfor為……準(zhǔn)備好，故將preparing改為prepared三、寫作參考范文：Aheateddiscussionaboutwhetherthetakeoutshouldbepermittedinourschoolisheldamongusstudents.Asforsomestudents,thetakeoutisconvenientandtasty.Besides,theycangetwhattheywantinashorttime.However,somestudentsholdthebeliefthatthetakeoutpackedintheplasticbagsisunsafetoeatbecausetheplasticbagsathightemperaturecandoharmtoourhealth.Moreover,
