让步状语从句，表示在某种相反条件下，主句陈述的情况或事实依然出现，这种从句常用连词though/although(虽然)，eventhough(即使)和but等引导。(1)though/although:两者意思相同，although不能放句末。而though放于句末意思为“但是，不过”。eg:Although/Thoughitwassnowing,itwasnotveryclod.虽然下着雪，但并不很冷。Itwashardwork,Ienjoyeditthough.工作很辛苦，但是我却做很愉快。（这里的though不能用although替换）(2)eventhough(=evenif)比though的语气强，常放于句首，动词常用一般现在时。引导的从句指把握不大或假设的事，意为“即使”，而though引导的从句指事实。(3)though与but不能连用，不能出现在同一个句子中。间接引语，主句是过去时态，间接引语时态也要求用过去时态，变化如下：直接引语间接引语一般现在时一般过去时was/were一般将来时过去将来时would/was/weregoingto(do)现在进行时过去进行时was/weredoing一般过去时过去完成时haddone现在完成时过去完成时haddone过去进行时过去完成进行时hadbeendoing过去完成时过去完成时（不变）haddone现在时态的客观真理不用改变时态由直接引语变间接引语时时态的变化：当我们用过去时转述别人的话（直接引语）时，原话中的一般过去时，过去进行时和现在完成时都要变成过去完成时。eg:“IhaveneverbeentotheUSA.”(Hesaid…)→HesaidhehadneverbeentotheUSA.“IwaswatchingTVthewholenight.”→HesaidhehadwatchingTVthewholenight.“Ihadaneggforbreakfast.”→Hesaidhehadhadaneggforbreakfast.以whether或if引导的间接引语要把一般疑问句或选择疑问句改为间接引语（宾语从句），首先要用连词whether或if来引导，意思是“是……呢，还是……呢；是不是；是否”，一般情况下两者可以互换，但当宾语从句出现了whether和ornot连用时，不可用if替代。其次把疑问句语序改为陈述句句语序（连词+主语+谓语），原来的助动词Do/Does/Did/要去掉，最后，动词的形式要作相应的变化。eg:Doeshisfatherworkinthatfactory?Doyouknow?→Doyouknowwhether/ifhisfatherworksinthatfactory?当将直接引语是祈使句的句子改为间接引语是，祈使句开头的动词原形要变为动词不定式，并在不定式的前面加上tell,ask,order等及物动词和宾语。当转述表示直接命令的句子是，用转述动词tell。当转述表示请求的句子时，用ask。eg:Theteachersaid,“Don’tbelate!”——Theteachertoldusnottobelate.Hesaid,“Pleasebequiet.”——Heaskedustobequiet.1.“Pleaseturndowntheradio,Sam.”saidMrsBrown.MrsBrown_____Sam_______________________________.2.MissLisaidtous,“Don’tplaywithfire!”MissLi_____us_______________________________.3.Shesaidtoherfriend,“Willyoupleasebuyaticketforme?”She_____herfriend_______________________________.4.MrGreensaidtohisson,“Don’tforgettoposttheletterforme!”MrGreen______hisson________________________________________.“Don’tlaughatotherswhentheyareintrouble.”MrsChensaidtoherdaughter.MrsChen______herdaughter_______________________________________.1.“IliveinRenminRoad.”Hesays.___________________________________________________________________.2.“IcanspeakalittleEnglish.”Demingsaid.___________________________________________________________________.3.“Thesunisbiggerthanthemoon.”Theteachersaid.___________________________________________________________________.4.“Stoptalkingandlistentome.”Saidtheteacher.___________________________________________________________________.5.“Don’tpaintonthebook.”Shetoldherbrother.___________________________________________________________________.6.“Youshouldgettoschoolontime”,theteachersaidtothestudent.___________________________________________________________________.7.“IwillvisittheGreatWallthissummerholiday”,Anniesaid.________________________________...
