中考網(wǎng)整理了關(guān)于2021年中考英語知識點之狀語從句的引導詞,希望對同學們有所幫助,僅供參考。
不同類型的狀語從句用不同的引導詞
1.時間狀語從句
、 時間狀語從句常用when, as, while, before, after,since, till, until, as soon as等連詞來引導。如:
While he was doing his homework, the telephone rang.
As he walked along the lake, he sang happily.
He had learned a little Chinese before he came to China.
After he finished middle school, he went to work in a factory.
、 在時間狀語從句里,用一般現(xiàn)在時代替一般將來時,用一般過去時代夫過去將來時。如:
I’ll ring you up as soon as I get to New York.
I would tell him everything when he came back.
2. 條件狀語從句
、 條件狀語從句通常由if(如果), unless(除非)引導。如:
What shall we do if it snows tomorrow?
Don’t leave the building unless I tell you to.
、 在條件狀語從句里,用一般現(xiàn)在時代替一般將來時,如:
I’ll help you with your English if I am free tomorrow.
He won’t be late unless he is ill.
③ “祈使句 + and (or)+ 陳述句” 在意思上相當于一個帶有條件狀語從句的復合句。如:
Hurry up, and you’ll catch the early bus.
= If you hurry up, you’ll catch the early bus.
Hurry up, or you’ll be late.
= If you don’t hurry up, you’ll be late.
