2018年公共英語(yǔ)四級(jí)重點(diǎn)語(yǔ)法資料：同位語(yǔ)從句

　　同位語(yǔ)從句

　　1、用作同位語(yǔ)的從句，叫同位語(yǔ)從句。它一般跟在某些名詞的后面，用以說(shuō)明或解釋前面的名詞，引導(dǎo)同位語(yǔ)從句的詞有連詞that，連接副詞how, when, where等，如：

　　I have no idea when he will be back. 我不知道他何時(shí)會(huì)回來(lái)。

　　We heard the news that our team had won. 我聽(tīng)到了我們隊(duì)勝利的消息。

　　2、that引導(dǎo)的同位語(yǔ)從句

　　在某些名詞后可用that引導(dǎo)同位語(yǔ)從句，如：

　　I had no idea that you were here. 我不知道你在這里。

　　The act that he won the first prize can’t be denied. 他取得第一名的事實(shí)不容否認(rèn)。

　　3、no idea+ wh-疑問(wèn)詞引導(dǎo)的同位語(yǔ)從句

　　I have no idea where he has gone. 我不知道他去了哪里。

　　She had no idea how she should do. 她不知道她應(yīng)該怎樣做。

　　4、應(yīng)注意的幾個(gè)問(wèn)題

　　(1)名詞demand ,proposal ,suggestion等后的同位語(yǔ)從句要用虛擬語(yǔ)氣，謂語(yǔ)為“should+動(dòng)詞原形“或只用動(dòng)詞原形，如：

　　The suggestion that the plan (should) be delayed will be discussed tomorrow.

　　推遲那項(xiàng)計(jì)劃的建議將在明天討論。

　　She refused the demand that he (should) do the work alone.

　　她拒絕了他單獨(dú)做那項(xiàng)工作的請(qǐng)求。

　　(2)同位語(yǔ)從句與定語(yǔ)從句的區(qū)別

　　同位語(yǔ)從句引導(dǎo)詞無(wú)意義，不充當(dāng)成分，但不可省略，同位語(yǔ)從句與其說(shuō)明的名詞或代詞應(yīng)為同一內(nèi)容，但定語(yǔ)從句的引導(dǎo)詞要在句中作成分，是對(duì)先行詞的一個(gè)限定說(shuō)明，如：

　　He told me the news that our team won.(that引導(dǎo)同位語(yǔ)從句)

　　He told me the news that(which) was very exciting.(that引導(dǎo)定語(yǔ)從句)

　　We are interested in the news that some foreigners will visit our school.(同位語(yǔ)從句)

　　We are interested in the news that he told us.(定語(yǔ)從句)
