中考網(wǎng)整理了關(guān)于2021年中考英語(yǔ)知識(shí)點(diǎn)：定語(yǔ)從句與同位語(yǔ)從句的區(qū)別，希望對(duì)同學(xué)們有所幫助，僅供參考。

　　定語(yǔ)從句與同位語(yǔ)從句的區(qū)別

　�。�1）定語(yǔ)從句修飾限定先行詞，它與先行詞是修飾關(guān)系；同位語(yǔ)從句說(shuō)明先行詞的具體內(nèi)容，它與先行詞是同位關(guān)系。

　　The plane that has just taken off is for Paris. （定語(yǔ)從句）剛剛起飛的那架飛機(jī)是開(kāi)往巴黎的。The fact that he has already died is quite clear. （同位語(yǔ)從句）他已經(jīng)去世了，這個(gè)事實(shí)很明了。

　�。�2）定語(yǔ)從句由關(guān)系代詞或關(guān)系副詞引導(dǎo)，關(guān)系詞在從句中擔(dān)當(dāng)相應(yīng)的句子成分，關(guān)系代詞在從句中作賓語(yǔ)時(shí)經(jīng)�？墒÷�。同位語(yǔ)從句主要由連詞that 引導(dǎo)，在從句中一般不擔(dān)當(dāng)成分；有時(shí)也由where, when, how, who, whether, what 等連詞引導(dǎo)，這些連詞則在從句中擔(dān)當(dāng)成分。

　　The news that he told me is true.（定語(yǔ)從句）他告訴我的消息是真的。The news that he has just died is true.（同位語(yǔ)從句）他剛剛?cè)ナ懒�，這個(gè)消息是真的。The problem that we are facing now is how we can collect so much money. (定語(yǔ)從句)我們現(xiàn)在面臨的問(wèn)題是如何籌集這么多資金。The problem how we can collect so much money is difficult to solve. （同位語(yǔ)從句）我們?nèi)绾位I集這么多資金，這個(gè)問(wèn)題很難解決。

　　（3）同位語(yǔ)從句與先行詞一般可以用動(dòng)詞be發(fā)展成一個(gè)完整的句子, 而定語(yǔ)從句則不能。

　　The idea that he we could ask the teacher for advice is wonderful. （同位語(yǔ)從句）我們可以向老師請(qǐng)教，這個(gè)主意不錯(cuò)。The idea was that we could ask the teacher for advice.The fact that the earth moves around the sun is known to all.（同位語(yǔ)從句）地球圍繞太陽(yáng)轉(zhuǎn)，這個(gè)事實(shí)人人皆知。The fact is that the earth moves around the sun.
