高中英語中有很多重要語法需要同學們掌握,狀語從句就是其中之一。狀語從句是每年高考的可能會功課,經常出現(xiàn)在選擇題中,狀語從句的種類比較多,同學們應該對每種用法都有所了解。為了幫助同學們學好高中英語狀語從句部分,下面愛智康小編為大家解析一下高中英語狀語從句用法。
高中英語狀語從句用法之原因狀語從句
主要區(qū)別because, as,since的用法。
because的語氣較強烈,用于回答why引起的問題;since和as用于雙方皆知的原因,一般放在句首,相對而言,since比as更正式一點;for引導的原因往往是一種補充說明,不用于句首,用逗號和前面的句子分開。
高中英語狀語從句用法之時間狀語從句
1.需注意各種從屬連詞,尤其是比較容易引起錯誤的搭配和不常使用的詞。如:hardly … when,no sooner … than,the moment,once,each time等。
2.注意時態(tài)的呼應。
時間狀語從句中用一般現(xiàn)在時態(tài)代替將來時態(tài)。此外,since引導的從句和主句時態(tài)不一致,hardly … when,no sooner … than時態(tài)的搭配都是需要引起注意的。
3.主句后跟until/till引導的句子時,要注意主句動詞的延續(xù)性(見例1)和終止性(見例2)的區(qū)別,還要注意對until引導的內容進行強調的用法(見例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引導的時間狀語從句的差別。
從句的謂語是短暫動詞時,不能用while引導;as用于表示兩個動作幾乎同時進行,而且從句的動詞不能是表示狀態(tài)的動詞(見例2);as之后不能用分詞作狀語;從句的謂語是持續(xù)性的時候,三者可以互換(見例1);when還可表示某事突然發(fā)生(見例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.
高中英語狀語從句用法之結果狀語從句
as和such的用法是一個難點,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
高中英語狀語從句用法之目的狀語從句
引導詞有:in order that, so that, in case, for fear that等。從句中的謂語常和may, might, can, could, should, would連用。當主句和從句的主語一致時,可用in order to和so as to加不定式來代替從句。
高中英語狀語從句用法之條件狀語從句
引導詞除了常用的if, unless, as/so long as之外,還有on condition that, provided that, supposing, in case,if only。條件狀語從句和時間狀語從句一樣,一般現(xiàn)在時表示將來時。尤其需要注意的是條件句可以是真實的或者虛擬的。如果是假設的條件,需要用虛擬語氣,在用虛擬語氣時,要特別注意錯綜條件和省略條件的句子以及虛擬條件和真實情況混雜的句子。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.
高中英語狀語從句用法之方式狀語從句
要注意由as if/though引導的從句虛擬和陳述語氣的使用區(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)
高中英語狀語從句用法之讓步狀語從句
要注意以下幾點:
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,(相當于and yet)放在兩個分句之間用逗號分開。
She wanted to have another try, though she had no chance.
3.However, whatever, whoever, wherever, whenever等在狀語從句中等同于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.

2.從句中常常省略一些相同的成分。
