2017英語(yǔ)中考知識(shí)點(diǎn):時(shí)間狀語(yǔ)從句
(1)時(shí)間狀語(yǔ)從句常用when, as, while, before, after, since, till, until, as soon as等連詞來(lái)引導(dǎo)。例如:
It was raining hard when got to school yesterday.
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.
(2)在時(shí)間狀語(yǔ)從句里,通常不用將來(lái)時(shí)態(tài),用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。例如:
I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his own eyes.
(3)在帶有till或until引導(dǎo)的時(shí)間狀語(yǔ)從句的主從復(fù)合句里,如果主句用肯定式,其含義是“一直到……時(shí)”,謂語(yǔ)動(dòng)詞只能用延續(xù)性動(dòng)詞。如果主句用否定式,其含義是“直到……才……”, “在……以前不……”, 謂語(yǔ)動(dòng)詞可用瞬間動(dòng)詞。例如:
The young man read till the light went out.
Let’s wait until the rain stops.
We won’t start until Bob comes.
Don’t get off until the bus stops.

What shall we do if it snows tomorrow?
Don’t leave the building unless I tell you to.
(2)在條件狀語(yǔ)從句里,謂語(yǔ)動(dòng)詞通常用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。例如:
I’ll help you with your English if 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(dāng)于一個(gè)帶有條件狀語(yǔ)從句的復(fù)合句。例如:

As it is raining, we shall not go the zoo.
Since you can’t answer the question, I’ll ask someone else.
(2)because表示直接原因,語(yǔ)氣最強(qiáng)。Because引導(dǎo)的原因狀語(yǔ)從句多放在主句之后?;卮鹩蓋hy提出的問(wèn)題,只能用because。As和since語(yǔ)氣較弱,一般用來(lái)表示明顯的原因。由as和since引導(dǎo)的原因狀語(yǔ)從居多放在句首。例如:
------Why aren’t going there?
------Because I don’t want to.
As he has no car, he can’t get there easily.
