句查询兴趣爱好的方式。故选E。4．F解析：文中第四段建议和那些与你有着相同兴趣爱好的人进行聊天交流，与别人交流得到的信息是最直观且及时的。与F选项中first­handknowledge相符。且F项中提到的interview意为“采访、访问”，与该段第一句中的“Talkwithotherpeople”意思相近，故选F。5．C解析：文中第五段第二句提到“Challengeyourselftotryanewactivityyouareinterestedinforaweekorso.”挑战自己，尝试一个你感兴趣的新活动，坚持一周左右。即对自己选择的爱好进行尝试，并查看尝试后的结果怎样。与C项相符，故选C。Ⅲ.读后续写阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。Ericwasworkinginasellingbusiness.Hehadbeenontheroadvisitingpeopleformorethanamonthwithoutgoinghome.Hecouldn'twaittogetbacktoseehiswifeandchildren.ItwasinguponMother'sDay,andheusuallytriedtomakeit“backhome”，butthisyearhewasjusttoobusyandtootired.Thedaywhenhewasdrivinginasmalltown,hesawaflowershop.Hesaidtohimself,“IknowwhatIwilldo,I'llsendmymothersomeroses.”Hestoppedandwentintotheflowershopandsawayoungmantalkingtothegirlinit“HowmanyrosescanIgetforfiftydollars,madam？”theboyasked.Thegirlwastryingtoexplainthatroseswereexpensive.Maybetheyoungmanwouldbehappywithsomethingelse.“No.Ihavetohaveroses，”hesaid，“mymomwasbadlysicklastyearandIdidn'tgettospendmuchtimewithher.Iwanttogetsomethingspecial.Ithastoberedroses,becausethatisherfavorite.”Hewasstubborn.ThegirlintheshoplookedupatEricandwasjustshakingherhead.SomethinginsideofEricwastouchedbytheboy'svoice.Hewantedtogetthoserosessobadly.Erichadbeenblessed(幸运的)inhisbusiness,andhelookedatthegirlandsilentlysaidthathewouldpayfortheboy'sroses.Thegirllookedattheyoungmanandsaid,“OK,Iwillgiveyouadozenredrosesforyourdollars.”Theyoungmanalmostjumpedintotheair.Hetooktheflowersandrandownthestore.Itwasworthmorethanfiftydollarsjusttoseethatkindofexcitement.Ericorderedhisownflowersandaskedthegirltohaveitdeliveredtohismother.Afterthat,withareliefhedrovedowntheroad.Notlongafterhisdriving,hesawtheboywalkingtoagr
