dy been to Beijing.如果賓語(yǔ)從句是表示客觀真理和規(guī)律的句子時(shí),用一般現(xiàn)在時(shí)。Our teacher told us the earth runs around the sun.③否定轉(zhuǎn)移:主句中謂語(yǔ)動(dòng)詞為think、believe,從句的否定要轉(zhuǎn)移到主句中,其反意疑問(wèn)句與從句一致。如:I don39。t think they39。ll wait to the last minute.I don39。t believe he did this,didn39。t he?2.定語(yǔ)從句用從句作定語(yǔ)的句子叫定語(yǔ)從句。定語(yǔ)從句一般放在它所修飾名詞或代詞的后面,這個(gè)名詞或代詞叫先行詞,引導(dǎo)定語(yǔ)從句的連接詞稱(chēng)為關(guān)系代詞或者關(guān)系副詞。關(guān)系代詞在從句中代表先行詞可以作主語(yǔ)、賓語(yǔ)、定語(yǔ)等。關(guān)系副詞代表先行詞在從句中可以作狀語(yǔ)。(1)what不能引導(dǎo)定語(yǔ)從句。(2)關(guān)系詞的分析須考慮它在定語(yǔ)從句中的成分。一是:當(dāng)先行詞是人,指人的關(guān)系代詞有who,whose,whom,that。如:The old man who/whom/that we met yesterday is a famous scientist.She knows the child whose parents have gone to Beijing.The man with whom my father talked just now is the headmaster.(=The man who/whom that my father talked with just now is our headmaster.)二是:當(dāng)先行詞是物,指物的關(guān)系代詞有which、whose(=of which)、that。如:(1)I like the movie which/that was directed by Feng Xiaogang.(2)The machines(which/that) we made last year were very good.(3)This is the city in which we have lived for 30 years.(=This is the city which/that we have lived in for 30 years.)(4)I live in the room whose windows are very big.(=I live in the room,the windows of which are very big.)【注意】指物時(shí),下列情況只能用that,不宜用which。①先行詞為不定代詞,如All,much,anything,everything,nothing,something,none,the one等。如:We are willing to do anything that is good to us.I have told them all(that) I know.②先行詞是序數(shù)詞或被序數(shù)詞修飾時(shí)。The first book that I read was an English novel.③先行詞是形容詞最高級(jí)或被最高級(jí)修飾時(shí)。This is the most exciting movie that I have ever seen.④如
