感情有着极大的鼓舞力量,因此,它是一切道德行为的重要前提,谁要是没有强烈的志向,也就不能够热烈地把这个志向体现于事业中。以下就是学而思1对1小编为大家整理的高中英语三大从句--状语从句,这是倪萍老师为大家精心准备的高中英语三大从句--状语从句。希望对大家可以有所帮助!
状语从句
1、定义:在复合句中修饰主句中的动词、形容词、副词和整个句子的从句。
2、状语从句从属连词:
引导词充当成分判断依据
状语从句时间when,while,as。。。状语主从句之间的逻辑关系,注意从属连词的意义
(一)时间状语从句
1、when、while(当。。。时)
When he came in,I was watching TV。
When I was watching TV,he came in。
While I was in Chengdu,I visited him。
Strike while he iron is hot。
易错点:
A。when引导从句中谓语动词既可以是延续性动词,也可以是瞬间性动词。while引导从句中谓语动词只能是延续性动词。
B。when,while不但作从属连词,也可作并列连词。当用作并列连词时,不能放句首:
when:“就在这(那)时,突然。。。。。。”
while:“然而”,常含有转折、对比之意
例句:
I was going to go to bed when the phone rang a second time。
我正要去准备睡觉,就在这时电话铃(突然)又响了。
She thought I was talking about her daughter,while,in fact,I was talking about my daughter。
她认为我正在说她的女儿,然而事实上我正在说我的女儿。
2、as引导的时间状语从句表示发生的时间比较短,且强调两个动作相伴进行。“一边。。。。。。一边。。。。。。”
As they picked tea,the girls sang happily。
As they picked tea,the girls sang happily。
3、before(在。。。之前),after(在。。。之后)
Mr。Brown had worked in a bank for a year before he came here。
After you use plastic bags,you mustn’t throw them about。
易错点:
A。It will be+时间段+before。。。“要过多久才。。。。。。”
It will be 4 years before he graduates。
B。It will not/won’t be+时间段+before。。。“没过多久就。。。。。。”
C。before long“很快,不久之后”
Before long,he went to America。
D。long before“很久以前”
That happened long before。
4、until(直到)
I’ll stay here until you come back。
He didn’t leave home until his father came back。
易错点:
A。until/till“直到。。。。。。时”,引导时间状从时,表示主句的动作发生在从句的动作之前。
当主句的谓语动词是持续性动词时,主句常用肯定形式;
当主句的谓语动词是非延续性动词时,主句常用否定形式,not。。。until。。。直到。。。才。。。。
B。当notuntil放于句首时,要用倒装,即:“Notuntil。。。+助动词+主语+谓语”。
She didn’t stop working until eleven o’clock。
Not until eleven o’clock did she stop working。
5、“刚一。。。。。。就。。。。。。”
as soon as
no sooner。。。than
hardly。。。when
scarcely。。。when
用法要求:只能表示过去的事情;主句只能用过去完成时,从句用过去时。
We had hardly begun when we were told to stop。
我们刚开始就被叫停。
They had no sooner arrived home than it began to rain。
他们一到家,天就开始下雨了。
6、since(“自从。。。”主句常用现在完成时态,从句常用一般过去时)
We have made many dumplings since we began to cook。
It’s been years since I enjoyed myself so much。
易错点:注意主将从现。
(二)地点状语从句(一般由where引导)
Where there is a will,there is away。
有志者,事竟成。
You should put the book where you found it。
你应该把书放在你找到它的地方。
易错点:注意和定语从句区分。
