现在的大多数跨国婚姻都是基于真爱,所以夫妇俩都很努力地克服双方的差异.Perhapsbecausemostoftodayscross-culturalmarriageoccurbecauseoftheirtruelove,thesecouplesmakegreatefforts/workhardtoovercometheirdifferences.,原因状语从句练习,3我们明天没有课,为什么不出去野餐呢?4你是学英语专业的,我猜想你能帮我解决这个句子.Sincewedonthaveclassestomorrow,whynotgooutforapicnic?SinceyouareanEnglishmajor,Iguessyoucanhelpmewiththesentence.,原因状语从句练习,连词as与since的用法差不多,所引出的理由在说话人看来已经很明显,或已为听话人所熟悉而不需要because加以强调.1由于周一是法定假日,所有的政府机关都将休息.Nationalholiday/governmentofficesAsMondayisanationalholiday,allgovernmentofficeswillbeclosed.连词for表示推断的理由,是对前面分句的内容加以解释或说明.昨晚下雨了,因为今天早上地都湿了.Itrainedlastnight,forthegroundiswetthismorning.,连词总结,比较而言:as和for引导的主,从句,二者处于平等位置.Because引导的从句显得比主句重要,强调原因.since引导的从句显得次要,而主句重要,以说明将要做什么事.,用介词表示因果关系,常见的介词有:Becauseof,dueto,owingto介词后面不能接从句Wehadanaccidentbecausehewascareless.Wehadanaccidentduetohiscarelessness.Owingtohiscarelessnesswehadanaccident.,思维训练,1_youareleavingtomorrow,wecaneatdinnertogethertonight.2_thecoldweather,wedicidednottogoout.3Itwas_hewassoyoungthathecouldtdoit.,目的状语从句,常用的从句连接词sothat,inorderthat,that,另外,在目的状语从句中常含有情态动词,比如may/might或could/can等.1我关掉了电视,好让我的室友安静地学习.IturnedofftheTVinorderthatmyroommatescouldstudyinpeaceandquite.2小的时候,我常常睡觉时候带着手电筒上床,这样我就可以偷看连环画册而不被父母发现.WhenIwasachild,IwouldtakeaflashlighttobedwithmesothatIcouldreadcomicbookswithoutmyparentsknowingaboutit.,结果状语从句,常见连接词:sothat,suchthat1我们学校食堂的饭菜质量真差,练苍蝇都飞到那里去减肥.Thefoodinourschoolcanteenissobadthatflies
