時(shí)間: 芷瓊1026 分享

  中考英語(yǔ)是對(duì)初中三年來(lái)學(xué)習(xí)成果的一個(gè)檢驗(yàn),也是對(duì)英語(yǔ)老師教學(xué)水平的檢測(cè)。接下來(lái)學(xué)習(xí)啦小編為你整理了2017英語(yǔ)中考知識(shí)點(diǎn),一起來(lái)看看吧。

  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.

  2017英語(yǔ)中考知識(shí)點(diǎn):條件狀語(yǔ)從句

  (1)條件狀語(yǔ)從句通常由if, unless引導(dǎo)。例如:

  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:

  Hurry up, or you’ll be late.

  =If you don’t hurry up, you’ll be late.

  Study hard and you will pass the exam.

  =If you study hard, you will pass the exam.

  2017英語(yǔ)中考知識(shí)點(diǎn):原因狀語(yǔ)從句

  (1)原因狀語(yǔ)從句通常由because, since, as引導(dǎo)。例如:

  He didn’t come to school because he was ill.

  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.

  Since we have no money, we can’t buy it.

  (3)because和so不能同用在一個(gè)句子里。
