16、词的宾语从句。难点一、作动词宾语例：Hetoldus（that）hefeltill.Doyouknowwhosedictionaryitis【注意】：1.ask的用法：在宾语从句中是“问”的意思，所以后面的从句肯定是存在“是”或者“否”的意思，所以引导词是if，whether或者wh-疑问词以及how（how引导的短语）,例：Sheaskedmeif/whetherhisbrotherwouldcomebackthenextday.Myteacheraskeduswhocleanedtheclassroom.2.doubt（怀疑）的肯定句接if/whether引导的宾语从句，但否定句和疑问句接

17、that引导的宾语从句。例：Idoubtwhether/ifhewillsucceed.Idonotdoubtthathecanrecitethepoem.Doyoudoubtthathewillwin?,难点二、作介词的宾语例：Hewasdeeplydispleasedbywhathadoccurredthatday.Yoursuccesswilllargelydependuponwhatyoudoandhowyoudoit.Hegoestothelibraryeverydayexceptwhenitisraining.【注意】：that引导的宾语从句只用在少数介词后，如：except,in

18、,but等。此时，that不能省略。例：Iknowlittleabouthimexceptthathelivesdownstairs.Hedifferedfromhisclassmatesinthathedevotedhissparetimetoreading.,难点三、作形容词的宾语例：IamnotsurewhatIoughttodo.Imafraid(that)youdontunderstandwhatIsaid.Imsurprised(that)Ididntseeallthatbefore.【注意】：beafraidthat和besurethat等句型是重点句型。,难点四、用it作形式宾

19、语的情况1和it作形式主语一样，我们常用it来作形式宾语，把真正的宾语从句放在句末，这种情况尤其出现在带复合宾语的句子中。例：WethoughtitstrangethatXiaoWangdidnotcomeyesterday.Hehasmadeitclearthathewillnotgivein.,2由于that引导的宾语从句一般不可以直接作介词的宾语，因此当介词后面需要用that从句作宾语时，必须使用it作形式宾语。例：YoumaydependonitthatIshallalwayssupportyou.Illseetoitthatyourproblemwillbedealtwithimme

20、diately.,难点五、宾语从句的否定转移在think,consider,believe,suppose,expect,fancy等动词后的宾语从句，如有否定意思，一般要把否定词前移到主句的语上，从句的谓语用肯定的形式。例：Idontthinkhecandoitbetterthanme.Idontbelievetheyhavefinishedtheirworkyet.Idontsupposehecares,doeshe?,【注意】：在下列情况下，宾语从句不否定转移：1think等词前有副词和表示强调的do例：Ireallyexpecthewontfailtheexamination.Idot

21、hinkthatheisnotfair.2think等词和其他词构成并列谓语：Ithinkandhopethathewontcheatatcards.3think等词作为插入语例：Hisdecisionisnotwise,Ithink.,难点六、if和when的辨析：演绎法：If可以引导宾语从句和条件状语从句，在宾从中，翻译成“是否”，在状语从句中，译成“如果”在宾语从句中，if放在动词的后面，且一般放在句中；而在状语从句中，他们一般放在句首或句中。E.g.:Iwonderifmyfriendwillcometoschooltomorrow.（宾语从句）Ifyoucometoschooltom

22、orrow,Iwilltellyouthenews.(状语从句),When也可以引导宾语从句和时间状语从句。在宾从中，翻译成“什么时候”，在状语从句中，译成“当的时候”。位置与if引导的句子位置是一致的。E.g.:Iwanttoknowwhenmymotherwillcomebackhome.Whenmymothercameback,Iwasdoingmyhomework.,难点七、if,whether在宾语从句中的区别1.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,findout等之后,介词后一般不用if2.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.3.whether后可以加ornot,但是if不可以.4.在不定式前只能用whether.如：Icantdecidewhethertostay.5.避免歧异时,我们常用whether而不用if.,真実一！,
