高中英語名詞性從句的知識(shí)點(diǎn)分析
高中英語的直接引語和間接引語的知識(shí)點(diǎn)
一. 直接引語和間接引語
(一)直接引述別人的原話，叫做直接引語;用自己話轉(zhuǎn)述別人的話，叫做間接引語。間接引語一般構(gòu)成賓語從句。直接引語必須放在引號(hào)內(nèi)，間接引語則不用引號(hào)。直接引語改為間接引語時(shí)，除將引語部分變成賓語從句外，還必須對直接引語中的人稱、時(shí)態(tài)、指示代詞、時(shí)間狀語、地點(diǎn)狀語等進(jìn)行改變。
1. 時(shí)態(tài)的變化：直接引語變?yōu)殚g接引語時(shí)，通常受轉(zhuǎn)述動(dòng)詞said, asked等的影響而使用過去化的時(shí)態(tài)，即把原來的時(shí)態(tài)向過去推，也就是一般現(xiàn)在時(shí)變?yōu)橐话氵^去時(shí)，現(xiàn)在進(jìn)行時(shí)變?yōu)檫^去進(jìn)行時(shí)，等等。例如：
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.
2. 人稱代詞、指示代詞、時(shí)間狀語、地點(diǎn)狀語等等的變化： 根據(jù)意義進(jìn)行相應(yīng)的變化，例如：
She asked Jack,“Where have you been?”
→She asked Jack where he had been.
He said,“These books are mine.”
→He said that those books were his.
(二)直接引語改為間接引語時(shí)，都使用陳述語序，但是因?yàn)樵涞木涫讲煌?，所以變成間接引語時(shí)所用的連詞會(huì)有所不同。直接引語如果是一般疑問句，用連接詞whether或if;如果是特殊疑問句，則用疑問詞引導(dǎo)間接引語。轉(zhuǎn)述的動(dòng)詞一般用asked，可以在其后加上一個(gè)間接賓語me, him, her, us等。如：
She said,“Is your father at home?”
→She asked me if/whether my father was at home.
“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.
直接引語如果是祈使句，改為間接引語時(shí)，要將祈使句的動(dòng)詞原形變?yōu)閹o的不定式，并在不定式的前面根據(jù)原句的語氣(即請求或命令)加上ask, tell, order等動(dòng)詞，如果祈使句為否定式，則在不定式前加not。其句型為：ask / tell / order someone (not) to do something. 例如：
She said to us,“Please sit down.”
→She asked us to sit down.
He said to him,“Go away!”
→He ordered him to go away.
He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.
二. 各種時(shí)態(tài)的被動(dòng)語態(tài)
被動(dòng)語態(tài)概述
被動(dòng)語態(tài)的概念：它是動(dòng)詞的一種形式，表示主語與謂語之間的執(zhí)行或被執(zhí)行關(guān)系。主動(dòng)語態(tài)表示主語是謂語動(dòng)作的執(zhí)行者，例如：They saw the little boy crying by the river. 被動(dòng)語態(tài)表示主語是謂語動(dòng)作的承受者，例如：The little boy was seen crying by the river.
被動(dòng)語態(tài)的構(gòu)成
被動(dòng)語態(tài)的形式是由“助動(dòng)詞be+動(dòng)詞的過去分詞”構(gòu)成。助動(dòng)詞be隨著主語的人稱、數(shù)、時(shí)態(tài)等的不同而變化。幾種常見時(shí)態(tài)的被動(dòng)語態(tài)形式如下：
1. 一般現(xiàn)在時(shí) am/is/are + 過去分詞
例如：Rice is planted in the south of China.
2. 一般過去時(shí) was/were + 過去分詞
例如：These trees were planted the year before last.
3. 一般將來時(shí) will/shall + be + 過去分詞
例如：A sports meeting will be held next week in our school.
4. 現(xiàn)在進(jìn)行時(shí) am/is/are + being + 過去分詞
例如：Your radio is being repaired now.
5. 過去進(jìn)行時(shí) was/were + being + 過去分詞
When he got there, the problem was being discussed.
6. 現(xiàn)在完成時(shí) have/has + been + 過去分詞
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.
7. 過去完成時(shí) had + been + 過去分詞
注意：
1.除了be之外的其它系動(dòng)詞如get, stay等也可以和過去分詞構(gòu)成被動(dòng)語態(tài)。例如：Their questions haven’t got answered.
2. 含有情態(tài)動(dòng)詞的謂語變成被動(dòng)語態(tài)使用“情態(tài)動(dòng)詞+ be + 過去分詞”結(jié)構(gòu)。例如：
More attention should be paid to the old in this country.
This work can’t be done until Mr. Black comes.
3. 含有“be going to”, “be to”等結(jié)構(gòu)的謂語，其被動(dòng)語態(tài)分別用“be going to + be + 過去分詞”和“be to + be + 過去分詞”。例如：
The problem is going to be discussed at the next meeting.
All these books are to be taken to the library.
4. 被動(dòng)語態(tài)與系表結(jié)構(gòu)的區(qū)別：“連系動(dòng)詞+用作表語的過去分詞”構(gòu)成的系表結(jié)構(gòu)，與被動(dòng)語態(tài)的形式完全一樣，所以應(yīng)注意它們的區(qū)別。被動(dòng)語態(tài)中的過去分詞是動(dòng)詞，多強(qiáng)調(diào)動(dòng)作;系表結(jié)構(gòu)中的過去分詞相當(dāng)于形容詞，多強(qiáng)調(diào)狀態(tài)。前者通常可用by 引出動(dòng)作的執(zhí)行者，而后者則不可以。例如：
The map was changed by someone.(被動(dòng)結(jié)構(gòu))
That custom remained unchanged for many centuries.(系表結(jié)構(gòu))
系表結(jié)構(gòu)中的過去分詞通?？杀籿ery修飾，被動(dòng)語態(tài)中的過去分詞往往要用much修飾。
例如：
He was very excited.(系表結(jié)構(gòu))
He was much excited by her words.(被動(dòng)結(jié)構(gòu))
5. 主動(dòng)形式表被動(dòng)意義。有些動(dòng)詞的主動(dòng)形式有被動(dòng)意味，如 open, read, sell, shut, wash, wear, write等。此時(shí)句子的主語一般是物。例如：
These books sell well. 這些書很暢銷。
The door won’t shut. 這門關(guān)不上。
The clothes wash well. 這些衣服很好洗。
