Inhibited in one direction, it now seems that the Mississippi is about to take another.状语简介概述状语与定语相同的地方是,都是前者附加成分;不同的地方是,它是谓语里的附加成分,而定语是主语或宾语里的附加成分.从句子的层次上看,状语是在第二个层次和第三个层次里的成分,有时甚至是更低层次的成分.状语的构成状语的构成经常充当状语的有形容词,副词,时间处所名词,能愿动词,指示代词,以及方位短语,介词短语,动宾短语,谓词性联合短语,谓词性偏正短语,谓词性主谓短语等.含有动量词的数量短语以及重叠式的数量短语(不论动量,物量)也可以充当状语.此外,少数名词带上表比况的助词也可以作状语.状语的书面标志——"地"状语的书面标志是结构助词"地".状语后面带或者是不带"地",情况比较复杂.一般讲来,数量短语,主谓短语,动宾短语等作状语时,大都带"地";而介词短语,方位短语,能愿动词,时间处所名词作状语时不能带"地",副词,单音节形容词作状语一般也不带"地".多层状语如果一个中心语前面有好几个状语(多层状语),那就应当注意它们的语序.多层状语的状语个数一般比多层定语的定语个数要少些,其语序也比多层定语的语序要灵活一些.多层状语的一般语序:a.表时间的名词或方位短语,介词短语;b.副词.c.表处所的介词短语或名词,方位短语;d.表情态的形容词或谓词短语;e.表对象的介词短语.其中副词的位置较为灵活,也可放置在第三项之后.一般状语和句首状语状语在句子中有两种位置:一种是在主语之后,谓语中心之前,如上文所举各例,这是状语的一般位置;另一种是放在主语的前面的,这是状语的特殊位置,这种状语可称"句首状语".状语的分类状语按其修饰的功能不同可分为八大类：时间状语，地点状语，条件状语，原因状语，目的状语，结果状语，让步状语和比较状语时间状语从句要点: 时间状语从句，由以下连词引导：when ，while， as， after ，before， as soon as， since ，till /until by the time 在时间状语从句中，要注意时态一致。

一般情况下主句是将来时的时候，从句要用一般现在时1.when当.....的时候Mozart started writing music when he was four years old.2.while当.....时He visited a lot of places while he was traveling.3. as在.....的同时；一边....一边.....He smiled as he stood up.4.after在....之后He left the classroom after he had finished his homework the other day.5.before 在......之前Mr. Brown had worked in a bank for a year before he came here.6. as soon as 一.....就（scarcely/hardly...when,no sooner than,the minute/moment,on/upon,directly等等）We began to work as soon as we got there.I will write to you as soon as I get home.7.since 自......以来到现在表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。

主句一般用现在完成时，从句用一般过去时Mr Green has taught in that school since he came to China three years ago.(还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示)8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语They walked till /until it was dark.Xiao Ming didn’t leave home till / until his father came back.9. by the time 到......为止 (所在句子的主句应用现在或过去完成时)By the time he gets there , his father has already gone.By the time I got to school, the class had already began.一 .由when, while, as引导的时间状语从句例如：When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。

When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！Strike while the iron is hot. 趁热打铁Will you watch my clothes while I have a swim. 我游泳的时候，请你照看一下我的衣服You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动Our headmaster laughed as she spoke.我们的校长边谈边笑a .when, while和as的区别when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词并且when有时表示“就在那时”。

When she came in, I was eating.(瞬时动词)When I lived in the countryside, I used to carry some water for him.（延续性的动词）While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）并且while有时还可以表示对比例如：While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生)I like playing football while you like playing basketball.（对比）b, As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后例如：We always sing as we walk.（as表示“一边……一边”）As we was going out, it began to snow.（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）c, as when while的辨析as when while都表示主、从句动作同时发生，三者差异如下：表示“一边。

一边"的意思as 强调两个动作同时进行，并表示对比时用于发生时间较段时d when1、还可以表示从句动词的动作在主几句动词的动作"之前 "或"之后"发生2、when=and then; at that moment (正在那个时候)3.常用于常见搭配中e while1、用于时间较长时2、 强调两个动作同时进行，并表示对比时有时这三个连词可以互换，有时不可以lt was raining hard when (as) I got there. ( 动作同时发生，when可换为as, 但不能换为while，因为get是点动词.)When I had read the article, he called me.( 从句动作发生在主句之前，注意时态表达，只能用when )When I got to the cinema, the film had begun.(从句的动作发生在主句之后，只能用when,并要注意时态)He was about to leave, when the telephone rang.( 此时不能放在句首主句动词一般表达 “正在” “即将”.while, as不能代替She thought I was talking about her daughter, while, in fact, I was talking about my daughter.(表转折，对比，when, as都不能代替它)While the alien was buying a souvenir, the girl called the police.(表示主句，从句的动作同时发生，while后引导的状语从句的动词必须是延续动词不能是点动词，因为它表示较长时间)Mother was worried because little Alice was ill, especially as (when/ while) father was away.(此时as ,when, while可通用)二 .由before和after引导的时间状语从句。

注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”还要注意主句和从句之间的时间关系当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后After表示主句动作发生在从句动作之后主句和从句的动作的时间关系正好与befor。
