一、什麼是狀語?什麼是狀語從句?

狀語

由具有

副詞性的詞、短語或句子充當

。例如:

I went to the countryside

last summer

To get good grades

, we should study hard。

為了取得好成績,我們應該努力學習。

Knowing Sally was ill

, her mother was worried about her。

I went to Shanghai

with my parents

以上斜體部分都是在句子

中作

狀語,狀語有名詞、不定式、分詞、介詞短語、形容副或句子充當。

He likes eating pears

very much

(簡單句,副詞very much做狀語,表示喜歡的程度。)

He likes eating pears

because they are yummy

(複合句,because they are yummy做狀語,表示原因)

在複合句中,

充當狀語的句子叫狀語從句

。狀語從句主要

修飾主句或主句中的動詞、形容詞和副詞

作用相當於副詞,又稱作副詞性從句。

3。 till/until引導的時間狀語從句:主句為肯定句時,主句的謂語動詞

延續性動詞;主句為否定句時,主句的謂語動詞是非延續性的,常用not…until…結構,意思是:直到……才

4。 as soon as 一……就……,如果主句為祈使句或一般將來時或含有情態動詞,從句用一般現在時表示將來,即:主祈從現、主將從現、主情從現。
