  初中英语语法,是初中英语中一个重要的板块。熟练的掌握这些语法知识,对于我们英语能力的整体提高,会有更好的帮助。那么具体的初中英语语法知识都包含了哪些呢?下面为大家整理了“初中英语语法知识剖析:状语从句”,供大家进行参考学习。

  状语从句是初中英语学习的重点,也是每年中考必考的内容之一。

  中考主要考查引导状语从句的连词、从句时态等方面。重点考查时间状语从句、条件状语从句、结果状语从句和比较状语从句。

  接下来我们就针对这四种从句的考查要点和连词的使用进行系统总结。

  状语状语是句子的重要修饰成分。

  状语是谓语里的另一个附加成分,它附加在谓语中心语的前面,从情况,时间,处所,方式,条件,对象,肯定,否定,范围和程度等方面对谓语中心进行修饰或限制。用来说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等。

  状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。其位置一般放在句末,但也可放在句首或句中。

  副词是一种用来修饰动词,形容词,副词或全句的词,说明时间,地点,程度,方式等概念。

  副词一般在句子中做状语.

  He speaks English very well.

  他英语说得非常好.(中的very是程度副词,用来修饰well。very well是修饰speak的程度状语)

  He is playing under the tree.

  他在树下玩儿.(under the tree是地点状语.)

  不定式在句子中可以作目的状语。

  I come specially to see you.

  我专门来看你.

  介词短语

  Ten years ago, She began to live in Dalian.

  The boy was praised for his bravery.

  从句作状语

  When she was 12 years old, she began to live in Dalian.

  If I am not busy tomorrow, I will play football with you.

  分词作状语

  Having had a quarrel with his wife, he left home in a bad temper.

  Inhibited in one direction, it now seems that the Mississippi is about

  to

  take another.

  时间状语从句

  在复合句中,由时间连接词引导的状语从句叫做时间状语从句。时间状语从句通常由when, while,

  as,after,before,since,until等词引导。

  引导时间状语从句的连词很多,为更于理解,可分为以下三类

  普通连词如after, as, before, since, till, until, when, while等。I will tell

  you

  after they leave.他们走我再告诉你。He dropped the glass as he stood

  up.他站起来时,把杯子摔了。I’d

  better have a think before I decide.我最好还是先想想再作决定。We have known each other

  since

  we were children.我们从小就认识。He waited until she was about to

  leave.他等着一直到她准备离开。Shut

  the door after you when you go out.出去时请随手关门。Stand still while I take

  your

  photograph.我给你拍照时站着不要动。

  表示“一……就”的连词表示“一……就”的时间连词除as soon as外,还有the moment, the minute, the

  second, the instant, immediately, directly, instantly, once, no

  sooner…than,

  hardly…when等。He started as soon as he received the news.他一接到消息就出发了。The

  moment I

  saw him I knew there was no hope.我一看到他就知道没希望了。I want to see him the

  minute

  (that) he arrives.他一来到我就要见他。The instant he opened the door he saw the

  thief.他一开门就看见了这个贼。Immediately he came I told him the news.他一来我就把消息告诉了他。Once

  he

  arrives, we can start.他一来我们就可以开始。We had no sooner set out than it began

  to

  rain.我们刚出发就下雨了。She had hardly arrived when it began to snow.她刚到就下起雪来了。

  含有time的连词这类连词主要有every time(每次),each time(每次),(the) next time(下次),any

  time(随时),(the) last time(上次),the first time(第一次), by the time(当……的时候)。You

  can

  call me any time you want to.你随时都可以给我打电话。Each time I went there, I saw

  him

  working.我每次去那儿都看见他在工作。Every time I see her I'll think of

  it.每次我看到她,我就想起这事。Next

  time you come in, please close the door.下次你进来,请关门。He didn't tell me the

  last

  time I saw him.我上次见到他时他没告诉我。The first time I heard about the firm closing

  down

  was when George told me.我最初听到公司倒闭的消息是乔治告诉我的。By the time he was taken to

  the

  hospital he was nearly dead.他被送到医院时已经几乎不行了。注意every time, each time,

  any

  time前不用冠词,(the) next time, (the) last time中的冠词可以省略,而the first

  time中的冠词通常不能省略。

  when, while 和 as 引导时间状语从句的用法

  一、when 的用法

  如果只从现象来看,when 从句用的最多的是一般过去时,而主句的时态没有限制,根据具体情况而定。 When he was a child

  he

  was always trying out new ideas.他小时候就常常试验一些新的设想。 When she came into my

  room, I

  was just reading a book.她走进我房间时,我正在看书。 Were you writing when the teacher

  came

  in?老师进来的时候,你在写信吗? Sorry, I was out when you called me.对不起,你打电话来的时候我出去了。

  He

  was on the point of leaving when someone knocked at the door.他正要走,这时有人敲门。

  I

  thought of it just when you opened your

  mouth.就在你要说话的时候,我也想到了。根据以上的例句,我们可以总结出一点when

  从句的A事件,相当于另一个事件B发生的时间点。也就是说,when

  从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,所以when

  多数情况下用的是一般过去时,则不用正在进行时。因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。根据这一点,有的文章补充说when

  从句的动词大多是瞬时动词。这种说法也可以参照。实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。

  When I

  got to the airport, the guests had left.当我赶到飞机场时,客人们已经离开了。 When he

  had

  finished his homework, he took a short rest.当他完成作业后,他休息了一会儿。 Why do you

  want a

  new job when you have got such a good one already?你已经找到如此好的工作,为何还想再找新的?

  You

  shall borrow the book when I have finished reading it.在我读完这本书后,你可以借阅。
