名師教你攻克英語(yǔ)四六級(jí)名詞性從句的絕招
語(yǔ)法不是死背硬記，而是歸納演繹。我不是叫你記憶，而是教你推導(dǎo)。一切的名詞性從句都是由五大句型推導(dǎo)出來(lái)的，所以我們先復(fù)習(xí)下五大句型。
主語(yǔ)+謂語(yǔ)：I do.
主語(yǔ)+謂語(yǔ)+賓語(yǔ)：I love you .
主語(yǔ)+謂語(yǔ)+間接賓語(yǔ)+直接賓語(yǔ)：I give her a kiss.
主語(yǔ)+系動(dòng)詞+表語(yǔ): You are an angel.
主語(yǔ)+謂語(yǔ)+賓語(yǔ)+賓語(yǔ)補(bǔ)足語(yǔ)：You make me happy.
名詞性從句包括：主語(yǔ)叢句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。四種名詞性從句的本質(zhì)是句子分別做五大句型中的主語(yǔ)、賓語(yǔ)、表語(yǔ)、同位語(yǔ)四種成分。具體地說(shuō)：五大句型中的主語(yǔ)換成一個(gè)句子，這個(gè)作主語(yǔ)的句子就叫主語(yǔ)從句;五大句型中的賓語(yǔ)換成一個(gè)句子，這個(gè)作賓語(yǔ)的句子就叫賓語(yǔ)從句;五大句型中的表語(yǔ)換成一個(gè)句子，這個(gè)作表語(yǔ)的句子就叫表語(yǔ)從句;五大句型中的同位語(yǔ)換成一個(gè)句子，這個(gè)作同位語(yǔ)的句子就叫同位語(yǔ)從句。
經(jīng)研究表明，有三種句子可以變名詞性從句，它們是：陳述句，一般疑問(wèn)句，特殊疑問(wèn)句，并且陳述句可以推導(dǎo)出一般疑問(wèn)句，一般疑問(wèn)句可以推導(dǎo)出特殊疑問(wèn)句。但是它們?nèi)齻€(gè)變名詞性從句的規(guī)則卻略有不同：
?、耜愂鼍浞謩e變主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。
陳述句：QQ doesnt have a girl friend.
變化規(guī)則：句首+that
① 主語(yǔ)從句:That QQ doesnt have a girl friend is a rumor.
?、?賓語(yǔ)從句:We dont know QQ doesnt have a girl friend.
?、?表語(yǔ)從句:The rumor is that QQ doesnt have a girl friend.
?、?同位語(yǔ)從句:The fact that QQ doesnt have a girl friend is rumor.
We know the fact that QQ doesnt have a girl friend.
發(fā)現(xiàn)規(guī)律：that在從句中不作成份。
Ⅱ一般疑問(wèn)句分別變主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。
一般疑問(wèn)句：Is there anything wrong with QQ? There is something wrong with QQ.
變化規(guī)則：第一步，變?yōu)檎b語(yǔ)序;第二步，句首+whether/if。
原則：if只用于賓從
例外：①介詞后的賓從;②放于句首賓語(yǔ)從句;③包含or not的名從
?、?主語(yǔ)從句：Whether there is something wrong with QQ is a rumor.
② 賓語(yǔ)從句：We dont know if/whether there is something with QQ.
③ 表語(yǔ)從句：The rumor is whether there is something wrong with QQ.
?、?同位語(yǔ)從句：The rumor whether there is something with QQ is spread.
We spread the rumor whether there is something with QQ.
發(fā)現(xiàn)規(guī)律：whether/if在句中不作成份。
Ⅲ特殊疑問(wèn)句分別變主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。
變化規(guī)則：正裝語(yǔ)序
?、?特殊疑問(wèn)句1：When can I become QQs girl friend?Can I become QQs girlfriend tomorrow? I can become QQs girlfriend tomorrow.
?、?主語(yǔ)從句：When I can become QQs girl friend is a question.
?、?賓語(yǔ)從句：I dont know when I can become QQs girl friend.
?、?表語(yǔ)從句：The question is when I can become QQs girl friend.
④ 同位語(yǔ)從句：The question when I can become QQs girl friend is puzzling.
I want to forget the question when I can become QQs girl friend.
發(fā)現(xiàn)規(guī)律：when/where/why/how在從句中作狀語(yǔ)。
?、?特殊疑問(wèn)句2：Which/whose girl is QQs girl friend? Is QQs girl friend FuRong? QQs girl friend is FuRong.
?、?主語(yǔ)從句: Which/whose girl QQs girl friend is is a question.
?、?賓語(yǔ)從句: We dont know which/whose girl QQs girl friend is.
?、?表語(yǔ)從句: The question is which /whose girl QQs girl friend is.
?、?同位語(yǔ)從句: The question which /whose girl QQs girl friend is is puzzling.
I want to forget the question which /whose girl QQs girl friend is.
發(fā)現(xiàn)規(guī)律：which/whose在從句中作定語(yǔ)，后面常常跟名詞。
⑶ 特殊疑問(wèn)句3： Whom will QQ marry? Will QQ marry FuRong? QQ will marry FuRong.
?、?主語(yǔ)從句: Whom QQ will marry is a problem.
?、?賓語(yǔ)從句: We dont know whom QQ will marry.
③ 表語(yǔ)從句: The problem is whom QQ will marry.
?、?同位語(yǔ)從句: The question whom QQ will marry is puzzling.
I want to forget the question whom QQ will marry.
發(fā)現(xiàn)規(guī)律：whom在從句中作賓語(yǔ)。
再給大家兩個(gè)特殊疑問(wèn)句作為練習(xí)，大家把這兩個(gè)句子用我們上述變化規(guī)則分別變?yōu)橹髡Z(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句，變化后再看看who和what分別在從句中作什么成份。
?、?特殊疑問(wèn)句4：Who can become Ws girl friend?
?、?特殊疑問(wèn)句5：What is the result of this marriage?
通過(guò)以上的講解和練習(xí)，我們會(huì)發(fā)現(xiàn)如下兩條規(guī)律：
?、?名詞性從句萬(wàn)變不離其宗變化規(guī)則;
?、?無(wú)論主句還是從句都有共同的基礎(chǔ)五大句型。
紛繁復(fù)雜的名詞性從句我已經(jīng)給大家歸納講解了，剩下的工作就是大家通過(guò)重復(fù)復(fù)習(xí)刻苦練習(xí)在閱讀與寫作的一瞬精彩演繹!
