是人的名詞或代詞,在從句中所起作用如下: Is he the man who/that wants to see you? 他就是你想見的人嗎?(who/that在從句中作主語) He is the man whom/ that I saw yesterday. 他就是我昨天見的那個(gè)人。(whom/that在從句中作賓語) 2) Whose 用來指人或物,(只用作定語, 若指物,它還可以同of which互換), 例如: They rushed over to help the man whose car had broken down. 那人車壞了,大家都跑過去幫忙。 Please pass me the book whose (of which) cover is green. 請(qǐng)遞給我那本綠皮的書。 3)which, that 它們所代替的先行詞是事物的名詞或代詞,在從句中可作主語、賓語等,例如: A prosperity which / that had never been seen before appears in the countryside. 農(nóng)村出現(xiàn)了前所未有的繁榮。(which / that在句中作主語) The package (which / that) you are carrying is about to e unwrapped. 你拿的包快散了。(which / that在句中作賓語) 關(guān)系副詞可代替的先行詞是時(shí)間、地點(diǎn)或理由的名詞,在從句中作狀語。 1)when, where, why 關(guān)系副詞when, where, why的含義相當(dāng)于介詞+ which結(jié)構(gòu),因此常常和介詞+ which結(jié)構(gòu)交替使用,例如: There are occasions when (on which) one must yield. 任何人都有不得不屈服的時(shí)候。 Beijing is the place where (in which) I was born. 北京是我的出生地。 Is this the reason why (for which) he refused our offer? 這就是他拒絕我們幫助他的理由嗎? 2)that代替關(guān)系副詞 that可以用于表示時(shí)間、地點(diǎn)、方式、理由的名詞后取代when, where, why和介詞+ which引導(dǎo)的定語從句,在口語中that常被省略,例如: His father died the year (that / when / in which) he was born. 他父親在他出生那年逝世了。 He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住過的地方。賓語從句是名詞性從句的一種,:動(dòng)詞的賓語從句,:I am sorry that I have troubled you so I have troubled you so long部分為賓語從句,that引導(dǎo)賓語從句無意義,不充當(dāng)句子成分.而定語從句是形容詞性從句,在句中做定語,修飾一個(gè)名詞或代詞,被修飾的名詞、,并在從句中充當(dāng)主語、賓語、:This is the book that you ,如:Shanghai is the city where I was ,相當(dāng)于介詞in+which,把先行詞city代入從句即:I was born in Shanghai.在句子中起賓語作用的從句叫做賓語從句。賓語從句分為三類:動(dòng)詞的賓語從句,介詞的賓語從句和形容詞的賓語從句。 賓語從句的連接詞:(一)、從屬連詞連接賓語從句的從屬連詞主要有that,if,whether。that引導(dǎo)表示陳述句的賓語從句,if和whether,whether...or not引導(dǎo)表示“是否”的一般疑問句的賓語從句。(二)關(guān)聯(lián)代詞連接代詞主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。連接代詞一般指疑問,但what,whatever除了指疑問外,也可以指陳述。(三)關(guān)聯(lián)副詞連接副詞主要有when,where,why,how,whenever,wherever,however等.賓語從句的用法 1.that引導(dǎo)賓語從句無意義,不充當(dāng)句子成分常省略。但下列情況除外:①.介詞賓語從句的that不能省略。②. and連接的兩個(gè)從句,兩個(gè)從句的that不能省略。He told me that he had two sons and that they both had gone to college. ③.在動(dòng)詞+it+賓語補(bǔ)足語+賓語從句結(jié)構(gòu)中,that不省略。I heard it said that he had gone abroad We found it impossible that he could finish it in such a short time ,if 引導(dǎo)賓語從句:兩詞可互換,但是下列情形除外:
