高中英語(yǔ)狀語(yǔ)從句用法解析

2016-06-30 12:13:53  來(lái)源:網(wǎng)絡(luò)整理

  高中英語(yǔ)中有很多重要語(yǔ)法需要同學(xué)們掌握,狀語(yǔ)從句就是其中之一。狀語(yǔ)從句是每年高考的可能會(huì)功課,經(jīng)常出現(xiàn)在選擇題中,狀語(yǔ)從句的種類比較多,同學(xué)們應(yīng)該對(duì)每種用法都有所了解。為了幫助同學(xué)們學(xué)好高中英語(yǔ)狀語(yǔ)從句部分,下面愛(ài)智康小編為大家解析一下高中英語(yǔ)狀語(yǔ)從句用法。

高中英語(yǔ)狀語(yǔ)從句


  高中英語(yǔ)狀語(yǔ)從句用法之原因狀語(yǔ)從句


  主要區(qū)別because, as,since的用法。


  because的語(yǔ)氣較強(qiáng)烈,用于回答why引起的問(wèn)題;since和as用于雙方皆知的原因,一般放在句首,相對(duì)而言,since比as更正式一點(diǎn);for引導(dǎo)的原因往往是一種補(bǔ)充說(shuō)明,不用于句首,用逗號(hào)和前面的句子分開(kāi)。


  高中英語(yǔ)狀語(yǔ)從句用法之時(shí)間狀語(yǔ)從句


  1.需注意各種從屬連詞,尤其是比較容易引起錯(cuò)誤的搭配和不常使用的詞。如:hardly … when,no sooner … than,the moment,once,each time等。


  2.注意時(shí)態(tài)的呼應(yīng)。


  時(shí)間狀語(yǔ)從句中用一般現(xiàn)在時(shí)態(tài)代替將來(lái)時(shí)態(tài)。此外,since引導(dǎo)的從句和主句時(shí)態(tài)不一致,hardly … when,no sooner … than時(shí)態(tài)的搭配都是需要引起注意的。


  3.主句后跟until/till引導(dǎo)的句子時(shí),要注意主句動(dòng)詞的延續(xù)性(見(jiàn)例1)和終止性(見(jiàn)例2)的區(qū)別,還要注意對(duì)until引導(dǎo)的內(nèi)容進(jìn)行強(qiáng)調(diào)的用法(見(jiàn)例3)。


  例1.He slept until 8 in the morning.


  例2.He did not get up until 8 in the morning.


  例3.It was not 8 in the morning that he got up.


  例4.Not until 8 did he get up.


  4.注意While,when,as引導(dǎo)的時(shí)間狀語(yǔ)從句的差別。


  從句的謂語(yǔ)是短暫動(dòng)詞時(shí),不能用while引導(dǎo);as用于表示兩個(gè)動(dòng)作幾乎同時(shí)進(jìn)行,而且從句的動(dòng)詞不能是表示狀態(tài)的動(dòng)詞(見(jiàn)例2);as之后不能用分詞作狀語(yǔ);從句的謂語(yǔ)是持續(xù)性的時(shí)候,三者可以互換(見(jiàn)例1);when還可表示某事突然發(fā)生(見(jiàn)例3),此外不能用其他的詞代替。


  例1.When/While/As he was in Australia, he learned to play the guitar.


  例2.As the days went by, she knew more about her hometown.


  例3.I was locking the door when the postman came.


  例4.When/While waiting for his turn, she picked up a magazine and began browsing through it.


  高中英語(yǔ)狀語(yǔ)從句用法之結(jié)果狀語(yǔ)從句


  as和such的用法是一個(gè)難點(diǎn),歸納如下:


  Such a/an + adj. + singular noun


  Such + adj. + plural noun


  Such + adj. + uncountable noun


  So + adj. + a/an + singular noun


  So + adj./adv.


  So + many/much/little/few + noun


  Such + little(小) + noun


  高中英語(yǔ)狀語(yǔ)從句用法之目的狀語(yǔ)從句


  引導(dǎo)詞有:in order that, so that, in case, for fear that等。從句中的謂語(yǔ)常和may, might, can, could, should, would連用。當(dāng)主句和從句的主語(yǔ)一致時(shí),可用in order to和so as to加不定式來(lái)代替從句。


  高中英語(yǔ)狀語(yǔ)從句用法之條件狀語(yǔ)從句


  引導(dǎo)詞除了常用的if, unless, as/so long as之外,還有on condition that, provided that, supposing, in case,if only。條件狀語(yǔ)從句和時(shí)間狀語(yǔ)從句一樣,一般現(xiàn)在時(shí)表示將來(lái)時(shí)。尤其需要注意的是條件句可以是真實(shí)的或者虛擬的。如果是假設(shè)的條件,需要用虛擬語(yǔ)氣,在用虛擬語(yǔ)氣時(shí),要特別注意錯(cuò)綜條件和省略條件的句子以及虛擬條件和真實(shí)情況混雜的句子。如:


  If you had taken his advice, there would be no trouble now.


  But for the police, the wounded driver would have lost his life.


  He would have lent you his new carat that time, but you are so careless driver.


  高中英語(yǔ)狀語(yǔ)從句用法之方式狀語(yǔ)從句


  要注意由as if/though引導(dǎo)的從句虛擬和陳述語(yǔ)氣的使用區(qū)別。


  It seems as if the ship will leave the harbor in a minute.(陳述)


  The cheats acted as if they had been working very hard the whole night.(虛擬)


  高中英語(yǔ)狀語(yǔ)從句用法之讓步狀語(yǔ)從句


  要注意以下幾點(diǎn):


  1. though和although都不能和but連用。


  2. although一般在句首,而though還可以作并列連詞,(相當(dāng)于and yet)放在兩個(gè)分句之間用逗號(hào)分開(kāi)。


  She wanted to have another try, though she had no chance.


  3.However, whatever, whoever, wherever, whenever等在狀語(yǔ)從句中等同于no matter how/what/who/where/when, 但在名詞性從句中不能等同。比較:


  However difficult the task may be, we will finish it within the time given.


  =No matter how difficult the task may be, we will finish it within the time given.


  Whatever he says, I will not change my mind.


  =No matter what he says, I will not change my mind.


  Whatever he said in the court was written down by a secretary for later use.


  ≠No matter what he said in the court was written down by a secretary for later use.


  高中英語(yǔ)狀語(yǔ)從句用法之比較狀語(yǔ)從句


  1.比較的對(duì)象要平衡一致。


  Her handwriting is more beautiful than anybody else’s in her class.


  2.從句中常常省略一些相同的成分。


  My parents do not love pop music as much as I (do).


  3.比較級(jí)常用表示程度的狀語(yǔ)有:much, still, far, a lot, a great deal, three times, a bit,rather, slightly等。
