在雅思閱讀文章中,狀語修飾動詞、形容詞、副詞或整個句子,通常由副詞、介詞短語、動詞不定式、分詞和從句等擔當。現(xiàn)在我們主要學習其中的一種形式,即從句做狀語成分,我們稱之為狀語從句。
狀語從句主要用來修飾主句或主句的謂語。一般可分為九大類,分別表示時間、地點、原因、目的、結果、條件、讓步、比較和方式。在今天的課堂中,我們先來學會識別時間,地點和原因狀語從句。
雅思閱讀常見狀語從句一. 時間狀語從句
1. 常用引導詞:when, while, as, as soon as, since,before, after, till, until?
下面我們結合例句主要重點區(qū)分下when,while, as, since,till, until的區(qū)別
a )when引導的從句,強調的可以是時間點,也可以是時間段;
Marry was about to leave when the telephone rang. when you apply for a job,you must present your credentials.
a) while 一般強調的是一段時間,往往和進行時連用;
When the teacher paraphrased the text in English, the students listenedattentively and took notes.
c)as后面一般加一段時間,但時間狀語從句用的較少;
We were having breakfast as she was combing her hair.
d)since 自從,主句常與完成時連用。
We’ve never met since we graduated from the college.
e) till /until till常用于肯定句,主句謂語為持續(xù)性動詞時用;until一般用于否定句,多與瞬間動詞連用;
Donald will remain in college till he finishes his Ph.D course.
I won’t go with you until I finished my homework.
2. 特殊引導詞:
a) hardly …when,no sooner … than一…就…
Tom had hardly entered the room when the class began.
b) every time
I will be in trouble every time I see him.
c) the minute, the moment, the second, the day,the instant
I fall in love with him the moment I saw him.
