賓語從句是英語復(fù)合句中的其中非常重要的從句之一。它是用一個(gè)句子做另一個(gè)句子的賓語,將這個(gè)句子叫做賓語從句。賓語從句做介詞或及物動(dòng)詞的賓語,F(xiàn)在從下列三個(gè)方面總結(jié)歸納
一,引導(dǎo)詞
例:I told him that he was wrong.
l在think,believe, suppose, expect等動(dòng)詞引起的賓語從句中,有時(shí)謂語盡管是否定意義,卻不用否定形式,而將think 等動(dòng)詞變?yōu)榉穸ㄐ问健?/P>
例:I don’t think you are right. (我認(rèn)為你做的不對(duì))
l在許多帶有復(fù)合賓語的句子中,that引導(dǎo)的賓語從句經(jīng)常移到句子的后面,而用it做形式賓語。
例:We think it wrong that he told a lie to everyone (我認(rèn)為他向每一個(gè)人撒謊是錯(cuò)誤的)
B,由連詞if、 whether 引導(dǎo)的表示“是否…”的賓語從句。Whether,if 在從句中不做句子的成分,一般情況下,whether和if 可以替換。
例:I don’t know if/whether he will come tomorrow.
The teacher asked if/whether we had finished the experiment.
l在介詞后面的賓語從句中不用if引導(dǎo)
例:Everything depends on whether we have enough money。
l賓語從句中有or not時(shí)不用if引導(dǎo).
例:I don’t know whether the movie star will come or not.
l和不定式連用作賓語時(shí)不用if引導(dǎo).
例:Whether to go there or not hasn’t been decided.
C,由wh-引導(dǎo)的賓語從句。連接代詞who,whom,whose, what, which,和連接副詞when, where, why, how 等連接的賓語從句,它們?cè)诰渲屑从羞B接從句的作用,又在句中充當(dāng)句子的成分。
例:Do you know which film they are talking about? (which做定語)
I don’t know where he lives. (where 做地點(diǎn)狀語)
二,賓語從句的語序,
賓語從句從句的語序必須是陳述語序,既連接詞+主語+謂語+其他成分
例:I believe that they will come soon.
He asked me whether I was a teacher.
They wanted to know what they can do for us.
二,賓語從句的時(shí)態(tài)。
賓語從句的時(shí)態(tài)受主句的限制,
既:主句是一般現(xiàn)在時(shí)態(tài),從句根據(jù)實(shí)際情況而定。
主句是一般過去時(shí)態(tài),從句用相應(yīng)的過去的時(shí)態(tài)。如果從句的動(dòng)作發(fā)生在主句之前,則從句要用過去完成時(shí)態(tài)。
例:
1)She says that she is a student.
She said that she was a student.
2)She says that she will fly to Japan in a week.
She said that she would fly to Japan in a week.
3)She says that she has finished her homework already.
She said that she had finished her homework already.
4)She says that she can sing a song in English.
She said that she could sing a song in English.
l如果賓語從句說的是客觀真理、自然現(xiàn)象或事實(shí)時(shí),這時(shí)賓語從句要用一般現(xiàn)在時(shí)態(tài)。
例:The teacher said that the earth goes round the sun.
He told me that Japan is an island country.
lCould you tell me…是用來征詢對(duì)方的意見,語氣委婉,并不表示過去。
例:Could you tell me when we will visit the Histury Museum?
注意事項(xiàng):
u由陳述句變成賓語從句時(shí),要注意人稱的變化。
例:She said: “I have been to England before.”
She said that she had been to England before.
She asked me: “Do you like maths?”
She asked me if I liked maths.
u賓語從句與簡(jiǎn)單句的交換。
由連接代詞和連接副詞引導(dǎo)的賓語從句,如果賓語從句的主語和主句的主語是同一個(gè)人時(shí),可以用“疑問詞+不定式
”做賓語的簡(jiǎn)單句結(jié)構(gòu)。
例:I don’t know what I should do next.
I con’t know what to do next.
He didn’t know where he would live.
He didn’t know where to live.
