【正文】 urprised 易混點(diǎn)一 ：同位語從句與定語從句的區(qū)別that引導(dǎo)的從句，是定語從句還是同位語從句，我們我們采用“試加 法”，來判斷。如： I still remember the day when I first came to “on the day”它沒有疑問詞“什么時(shí)候”的意義，因此是定語從句。易混點(diǎn)二：reason后面的名詞性從句reason做主語時(shí)，后面的表語從句表示原因是要用that引導(dǎo)，一般不用because或why，而用it，this或that做主語時(shí)，后面的表語從句可用because或why引導(dǎo)。本句型的意思是：理由是：。本句型意為：這就是。本句型意為：這是因?yàn)?。的緣故。本句型意為：這就是。That was why he fell ：what、whatever、who、whoever等引導(dǎo)的名詞性從句 我們可以通過與定語從句的轉(zhuǎn)化知道兩組在意義上的差別。而what、who、when、where則是特指。而no matter +疑問詞只能引導(dǎo)讓步狀語從句。易混點(diǎn) whether與if（不做考查）二者都可以作“是否”講，能引導(dǎo)名詞性從句，都不能省略。如： We discussed whether we should close the 、表語從句、同位語從句時(shí)都用whether，不用if。如： I wonder whether or not he has arrived at the don’t know whetherif I can e or ，則多用if，而不用whether。如：I haven’t settled the question of whether I will go back doesn’t know whether to get married now or ：名詞性從句 you see _____ I mean? me_____ is on your must stick to _____ we have agreed me see _____I can repair the radio or in mind _____ the teacher said you advise me _____ book I should read first? was criticized for _____ he had you kindly tell me _____ I can get to the Beijing Railway Station? was very much impressed by _____ she had seen in took it for granted ___ they were not really don39。m afraid _____ the little girl will have to be operated walked up to _____ I you tell me _____ that gentleman is? 39。 t been decided was said here must be kept is still a question _____ we shall have our sports is strange _____ she have left without saying a is very clear _____ our policy is a correct Mr Zhang said is quite 39。？ 。多聽，多寫。我們聽到了這樣的消息我國(guó)有發(fā)射一顆人造衛(wèi)星。you cannot be sure of something _____ you might getin the future.[2007 安徽卷]。thatD./。why 。because 。they are waiting to see _______ he will , how , what , how , what you answer questions in a job interview, please remember the golden rule: Always give the monkey exactly _______ he wild flowers are so special I would do _______ I can to save she was invited to the ball made her very ______ cake you like and leave the others for ______ es in , who , whoever , whoever , whoever had neither a raincoat nor an I got wet ’s the reason ’s why ’s ’s because has helped to save the drowning girl is worth one medicine works in a human body is a question ____ not everyone can understand 。which 。that 。that 引導(dǎo)的是一個(gè)主語從句，句首的it為形式主語。答句為省略句，其完整形式為 I was trying to prove to the police where I was lastnight，在此 where 引導(dǎo)的是一個(gè)賓語從句。what 引導(dǎo)的是表語從句，what 在此相當(dāng)于 the things that。句首的 it 是形式主語，空格處所填詞用于引導(dǎo)主語從句。（注意：不能選 A，因?yàn)?that 引導(dǎo)名詞性從句時(shí)不能充當(dāng)句子成分） A。句中空格后文表明的是結(jié)果，故用 why。what 在此引導(dǎo)主語從句且在從句作賓語，它相當(dāng)于 the thing that。兩空均填 what，均用于引導(dǎo)賓語從句，因?yàn)閮蓚€(gè)賓語從句中的動(dòng)詞 said 和do 均缺賓語，而在各個(gè)選項(xiàng)中只有 what 可用作賓語。what 引導(dǎo)賓語從句。句意是：當(dāng)你找工作面試回答問題時(shí)，請(qǐng)記住這條黃金定律：永遠(yuǎn)給予對(duì)方確實(shí)想要的東西。I can to save them 為 I can do to save them 之略，此句中的 do 缺賓語，故選 whatever。that 在此引導(dǎo)主語從句，無詞義，也不充當(dāng)句子成分。 C。 B。如下面一題選 D：I got wet all I had neither a raincoat nor an ’s the reason’s why ’s why’s because D。 A。第五篇：名詞性從句及習(xí)題高中語法名詞性從句在復(fù)合句中起名詞作用的從句叫做名詞性從句。216。因此，這四種從句通稱為名詞性從句。主語從句通常由從屬連詞that，whether，if和連接代詞what，who，which，whatever，whoever以及連接副詞how，when，where，why等詞引導(dǎo)。例如：What he wants to tell us is not clear.（what既保留自己的疑問含義，又起連接作用，并從句中充當(dāng)成分）It is known to us how he became a writer.（how既保留自己的疑問含義，又起連接作用，并從句中充當(dāng)成分）Where the English evening will be held has not yet been announced.（where既保留自己的疑問含義，又起連接作用，并從句中充當(dāng)成分）有時(shí)為避免句子頭重腳輕，常用形式主語it代替主語從句作形式主語放于句首，而把主語從句置于句末。常用句型如下：（1）It + be + 名詞 + that從句（2）It + be + 形容詞 + that從句（3）It + be + 動(dòng)詞的過去分詞 + that從句（4）It + 不及物動(dòng)詞 + that 從句另注意在主語從句中用來表示驚奇、不相信、惋惜、理應(yīng)如此等語氣時(shí)，謂語動(dòng)詞要用虛擬語氣“(should)+do”，常用的句型有：It is necessary(important, natural, strange, etc.)that ? It is a pity(a shame, no wonder, etc.)that?It is suggested(requested, proposed, desired, etc.)that?表語從句在句中作表語的從句叫表語從句。其基本結(jié)構(gòu)為：主語 + 系動(dòng)詞 + that從句。例如： The reason why he was late was that he missed the train this morning賓語從句:動(dòng)詞的賓語從句,
