1、（直擊高考）2013高考英語 語法重難點(diǎn)系列 專題10 名詞性從句考點(diǎn) 在句子中起名詞作用的句子叫名詞性從句(Noun Clauses），引導(dǎo)名詞性從句的詞叫連詞。 名詞性從句又分別稱為: 主語從句、賓語從句、表語從句、同位語從句 主語從句：是在復(fù)合句中充當(dāng)主語的從句，常放在謂語動(dòng)詞之前或者用形式主語it代替，將其本身放在句尾。 例如：1. That he came here just now has been proved. 他剛才來的這里得到了證實(shí)。 解析：That he came here just now在謂語has be

2、en proved的前面，所以是主語從句。 2. It’s true that we are going next week. 我們下星期走是真的。 解析：真正的主語是 that we are going next week，前面的it是形式主語。 賓語從句：在復(fù)合句中作賓語的名詞性從句，通常放在主句謂語動(dòng)詞（及物動(dòng)詞）和介詞之后。 例如：1. We all know what he is. 我們都知道他是干什么的。 解析：what he is作及物動(dòng)詞know的賓語從句。 2. His worry is ab

3、out whether he can succeed. 他的擔(dān)憂是關(guān)于他是否能成功。 解析：whether he can succeed作介詞about的賓語從句。 表語從句：在復(fù)合句中作表語的名詞性從句，放在系動(dòng)詞之后，一般結(jié)構(gòu)是：主語+聯(lián)系動(dòng)詞+表語從句 例如：1. His question is where he can buy a house. 他的問題是他能在哪里買房子。 解析：where he can buy a house是聯(lián)系動(dòng)詞is后面的表語從句。 2. This is why we can’t get t

4、heir support. 這就是我們得不到他們支持的原因。 解析:why we can’t get their support是聯(lián)系動(dòng)詞is后面的表語從句。 同位語從句：是用以說明所修飾名詞的具體內(nèi)容的，它與被修飾的詞語通?？梢詣澋忍枴? 例如：We heard the news that our team had won. 我聽說了我們球隊(duì)獲勝的消息。 為了思維的連貫性，此專題我們不以從句的分類來講，而以連詞的分類講。 引導(dǎo)名詞性從句的連詞主要有以下幾類： 1.具有詞匯意義的連詞 （what, how, who, wh

5、en, where, why,whose, which） 2.沒有詞匯意義的that（that在句中沒有如何意義，只起連詞的作用） 3.if/whether （是否） 4.具有雙重身份的what 5.疑問詞+ ever（whatever、whoever、whomever、however、whenever、wherever、whichever） 一、具有詞匯意義的連詞 1. I know when he was born. 我知道他什么時(shí)候出生的。 2. Where he lives is known to us all. 他住在哪里我們大家都清楚。

6、3. My question is how you came to school. 我的問題是你怎樣來的學(xué)校。 4. He told us why she was late. 他告訴我們她為什么遲到。 5. Please let me know what you are . 讓我們知道你是干什么的。 6. Which team will win isn’t clear. 哪只隊(duì)將要贏還不清楚。 從上面的例句我們可以看出上述引導(dǎo)名詞性從句的連詞都具有詞匯意義。 二、that的用法 1.I know that your na

7、me is Tom. （賓語從句） 我知道你名字叫湯姆。 2.The news that they won the match excited us very much. （同位語從句） 他們獲得了比賽勝利的消息使我們都非常興奮。 3. That he often helps my sister makes me happy. （主語從句） 他經(jīng)常幫我妹妹使得我開心。 4.My demand is that you (should ) try to study hard. （表語從句） 我的要求是你們盡力努力學(xué)習(xí)。 從上述四個(gè)句子我們可以看出that在句中不具有

8、任何詞匯意義，也不充當(dāng)任何成分。 一）that引導(dǎo)主語從句常用it作形式主語的情況： （should) do.（因?yàn)槠鋭?dòng)詞都是表“建議、命令、要求、主張、決定”等） 動(dòng)詞原形的虛擬語氣。 1） 老師建議我們早上早起。 The teacher suggests that we (should) get up early in the morning.

14、ported/considered…that從句（據(jù)說/據(jù)報(bào)道/據(jù)認(rèn)為。。。。。。） a. 據(jù)說/認(rèn)為/報(bào)道你是個(gè)好醫(yī)生。 It is said/considered/reported that you are a good doctor.→ You are said/considered/reported/to be a good doctor. b. 據(jù)說他們正在國外踢球。 It is said that they are playing football in a foreign country.→ They are said to be playing
