让步状语从句的从属连词及其用法 条件状语从句的从属连词及其用法
当主句和从句表示两个相似的情 况时，so可以用于表示结果。例 如。
非延续性动词的用法
非延续性动词强调动作的瞬间完成，不能 与时间段连用。例如，“The train arrived at the station just now.”（火 车刚刚到站。）。 o'clock, on Monday等。例如，“I finished my homework at。
非延续性动词有时也可以表示一种状态， 如。
be doing还可以用于表示习惯或 常规，即经常性的行为或状态。 例如。
We are meeting on Sundays. （我们每周日见面。）。
be about to do的意义和用法
be about to do表示即将做某事，强调 即将发生的动作或情况。例如。

可以用though替代。
例如：

2. as表示“因为”、“由于”,引导原因状语ቤተ መጻሕፍቲ ባይዱ从句,
其语气不如because强;
通常为附加说明的理由,且是已知晓的原因;
主句与从句没有逻辑上的因果关系。
例如：
• As she was not well, I went there alone. 因为她身体不好,所以我独自到那里去了。
5. as表示“像……一样”,引导比较状语从句;
对主句和从句的动作或状态加以比较,说明它 们之间有相似之处;

• 4. as表示“按照”、“依照”、“像”, • 引导方式状语从句,从句置于主句之后。
状语从句讲解
状语从句讲解状语从句由从属连词(subordinating conjunctions)引导。
注意状语从句与主句之间的逻辑关系，选择正确的连词;有些连词能引导多种状语从句。
一、时间状语从句引导时间状语从句的从属连词主要有:after，as，before，once, since，till，until，when，whenever，while，as soon as;另外有些词如:immediately(立刻)，directly(直接的)，instantly(立即地)用于as soon as 意义时,有些名词词组如the moment(片刻)，the instant(立即的)，the minute，the day，the year，every time，next time,each time 等也用来引导时间状语从句:The mother didn't go to bed until her little daughter returned home last night. 昨晚母亲等到她的小女儿回家才睡觉。
I'll explain it to you immediately I've finished reading the letter. 我读完信立刻给你解释。
You see the lightning __________it happens，but you hear the thunder later.A）the instant(立即) B）for an instantC）on the instant(马上) D）in an instant(马上)闪电一发生,你立刻就能看到它,但雷声,你迟一点才能听到它。
（B4，1997.1-38，A对。
）No sooner ... than 和hardly/scarcely/barely ... when 也用来引导状语从句,意思是“一……就……”;如果将no sooner，hardly, scarcely，barely放在句首,就用倒装结构。
状语从句常用连接词归纳
状语从句常用引导词归纳引导状语从句的词语叫从属连词。
不同作用的状语从句通常由不同的从属连词来引导。
如：1. 引导时间状语从句的从属连词主要有when, while, as, whenever, before, after, since, until, till, as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once等。
2. 引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case 等。
3. 引导目的状语从句的从属连词主要有 in order that, so that, in case, for fear等。
4. 引导结果状语从句的从属连词主要有so that, so…that, such…that等。
5. 引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that), considering (that) 等。
6. 引导让步状语从句的从属连词主要有although, though, even though, even if, while, however, whatever, whoever, whenever, wherever等。
7. 引导方式状语从句的从属连词主要有as, like, as if, as though, the way等。
8. 引导地点状语从句的从属连词主要有where, wherever, everywhere等。
9. 引导比较状语从句的从属连词主要有than和as…as。
as long as和so long as引导条件状语从句的区别as long as 和so long as 均可表示“只要”，用于引导条件状语从句，两者没什么区别。
引导状语从句的从属连词
引导状语从句的从属连词一、常见的引导时间状语从句的从属连词when这个词可太常用啦。
就像咱们平常讲故事的时候说“当太阳落山的时候，小鸟就飞回巢里了”，这里的when就把“太阳落山”和“小鸟回巢”这两件事在时间上联系起来了。
它特别的灵活，可以表示某个具体的时间点，也可以表示一段时间。
比如说，When I was a child, I liked to play in the park.（当我还是个孩子的时候，我喜欢在公园玩。
）这就是说在我小时候这个时间段里的事情呢。
还有while，这个词感觉就像是在两件事情同时进行的时候出场的小指挥。
比如说，While my mother was cooking, I was doing my homework.（我妈妈做饭的时候，我正在做作业。
）你看，做饭和做作业这两件事是同时发生的，这时候while就派上用场啦。
as呢，它也有当……的时候的意思。
不过它还有一种“随着”的感觉哦。
像As time goes by, we are getting older.（随着时间的流逝，我们正在变老。
）它就把时间的推移和我们变老这件事联系起来啦，有一种缓缓进行的感觉呢。
after和before就比较好理解啦。
after就是在……之后，Before就是在……之前。
比如说，After I had breakfast, I went to school.（我吃完早饭之后，我去上学了。
）Before it rains, the sky often gets dark.（在下雨之前，天空经常会变黑。
）这两个词就像时间线上的小标记，清楚地告诉我们事情的先后顺序。
二、引导原因状语从句的从属连词because那可是原因状语从句里的大明星啦。
咱们平时解释为什么的时候，就经常用到它。
比如说，I didn't go to school yesterday because I was ill.（我昨天没去上学因为我生病了。
谈谈由特殊从属连词引导的状语从句的用法
解题技巧在历年高考题中，完形填空题的语篇多是记叙文、议论文以及夹叙夹议等类型，很少出现说明文类型的语篇。
然而，2022年全国乙卷中却出现了说明文体裁的文章，其主题语境是关于人与社会。
体裁的变化将会给学生解答此类题型带来一些微妙的变化，同时也给学生的复习带来一些启示。
下面笔者将分别从体裁特征、搭配衔接、分析语境等方面，针对说明文体裁的完形填空题进行分析，从而为学生解题技能的提升提供一定的借鉴。
一、解读体裁特征，理清行文结构说明文一般是按照时间、空间以及逻辑顺序展开，通常主题鲜明，结构清晰，其语言具有简明准确、客观、条理分明等特点，着眼于对知识、事物的解说与阐明，往往传递的是某一领域内的知识。
学生可通过整体阅读，提取每段的主旨大意，获取语篇的主要内容，同时理清语篇的整体架构。
2022年乙卷完形填空题的语篇总共分为五个段落。
各个段落大意为：引出人们针对儿童捉迷藏这种现象的普遍认知；阐述学龄前儿童在玩捉迷藏游戏中的奇怪现象；最新研究与普遍认知相矛盾；阐述最新研究实验过程；研究结果表明，学龄前儿童不擅于躲藏，其原因是他们坚信与他人之间的“相互尊重与认可”。
由此，该语篇的整体架构即是：引出普遍观点、新研究与普遍认知相佐、实验证明、得出结果。
这样，学生便对每个段落的主旨以及语篇的核心观点有了清晰的认识，并以此为依据，对各段的内容以及细节进行理解与分析，将选项内容置于意义的理解中，确定最佳选项。
二、捕捉搭配衔接，辨析句段逻辑学生借助固定搭配解题，主要是从动词与介词、介词与名词、固定短语、句式搭配等几个方面去思考，以此为依据，辨析句句、句段之间在意义上存在的逻辑关系。
此外，句与句，段与段之间使用的表示过渡、衔接的词语也为破题提供依据，辅助学生提高解题的准确率。
如，第45-46题，其所在句子的句首出现了表示转折意义的but，由此推测其后的意思与前文描述的观点相矛盾，即这种研究结果是令人惊讶的，则第45题选C（surprising），46题选C（contradicted）。

从属连词状语从句一、重点知识归纳及讲解（一）从属连词从属连词是引导状语从句，宾语从句及其他从句的连词。
1．引导状语从句的从属连词有：1）when, while, before, after, as soon as, until, since等，引导时间状语从句。
2）because, as, since等引导原因状语从句。
3）if, as long as等引导条件状语从句。

5）so…that…, such…that…等引导结果状语从句。
6）so that引导目的状语从句。
7）as⋯as⋯；than等引导比较状语从句。
2．常用从属连词的辨析1）when, as, whilewhen, as, while都表示“当…的时候”，但when引导的时间状语从句的动作和主句的动作可以是同时发生，也可以先后发生，when既可指时间点，也可指一段时间，所以既可引导一短暂动作动词，也可引导持续性动作的动词。
用as作从属连词引导时间状语时强调主句和从句的动作并行发生，不指先后，尤指短动作或事件同时发生。
如：As I looked, someone came near.（正当我看的时候，有个人走上前来。
）as还可说咱两种正发展或变化的情况，意为“随着”。
如：As spring warms the earth, all flowers begin to bloom.（随着春回大地，百花开始绽放。
）表示主从句动作同时，as意为“一边…一边…”。
如：He hurried home, looking behind as he went.（他匆匆忙忙跑回家，一边走一边回头望。
）while只指一段时间，从句中的谓语动词不能用终止性动词，强调某一段时间内主从句动作同时发生，常对同类的动作进行对比。
如：While we were waiting for a bus, it was raining hearily.（我们在等车时，天正下着大雨。
）2）till和untiltill和until都表示“直到…为止”。
主句用延续性动词，主句和从句都用肯定式：意为“直到…才”。
主句用终止性动词，从句用肯定式，主句用否定式。
until较till正式，until引导的时间从句可以放在句首。
例如：She won't go away till you promise to help her.直到你允诺要帮助她，她才走开。
Until you told me, I had heard of nothing what happened.直到你告诉我，我才知道发生了什么事。
3）sincesince引导的时间状语从句常用一般过去时，其主句一般使用现在完成时。
例如：Jim has been in the factory for two years since he left school.从吉姆毕业起，他在这家工厂工作两年了。
（二）状语从句修饰主句中的谓语动词，形容词或副词等的从句叫状语从句。
例如：He didn't go to school yesterday because he was ill.（修饰动词go）昨天他没去上学，因为他病了。
We must study so well as our teacher hoped.（修饰副词well）我们应该学得你我们老师希望的那么好。
Lucy is younger than Jim(is)。
（修饰形容词younger）露茜比吉姆年轻。
状语从句的语序应是主语+谓语+其他成分，即陈述句的语序。
状语从句的位置，可以放在主句前面或后面，但是若放在主句前面，要用逗号与主句分开；主句若是疑问句，那么时间状语从句只能放在主句的前面。
1）时间状语从句时间状语从句由when, while, after, before, since, as soon as, till, until等连词引导。
例如：I went to bed after the TV play was ever.电视剧完了以后我上床睡觉。
Could you look after her while we're away?我们不在时你能照顾她吗？She has taught in this school since she came to this city in 1989.自从一九八九年她来到这座城市以来一直在这所学校教书。
Wait until I come back.请你等到我回来。
注意：如主句是一般将来时，则表示将来的时间状语只用一般现在时。
例如：I'll write to you as soon as I get to Beijing.我一到北京就将写信给你。
It will get warmer and warmer when spring comes.春天来临时，天气将变得越来越暖和。
2）原因状语从句原因状语从句由because, as, since等连词引导。
例如：He sold the car because it was too small.他卖掉那辆小汽车，因为它太小了。
Since you won't help me, I must do the job myself.你既然不帮我忙，我必须自己做这项工作。
As my mother is away at this moment, I have to look after my younger sister.由于我的妈妈现在不在，我不得不照顾我的妹妹。
注意：a）because, as, since, for的用法辨析because, as, since, for都是表示各种理由的连词，但because多表示所叙述的理由是本句的重点，故because所引导的从句常放在句末。
例如：Why was he absent? Because he was badly ill.他为什么缺度？因为他病得很重。
as, since用于表示理由是已知，而理由以外才是叙述的重点，两者皆多用于句首，但要注意since重形式，as多表示理由以外的才是重点。
例如：As it is raining, let's stay as home.因为下雨，我们就留在家里吧。
Since you have no license, you are not allowed to drive.因为你没有驾驶执照，所以你不可以开车。
for不用于句首，而用于主句之后，补充说明理由；主句表推测时，用for说明原因。
例如：I'll follow his advice, for he is a doctor.我会听从他的劝告，因为他是医生。
b）because of也是表示原因状语，但后面只能跟短语。
例如：I stayed at home because of the bad weather.因为天气不好我留在家里。
3）比较状语从句比较状语从句由than或as来引导。
例如：I feel better now than (I was) before.我现在觉得比以前好了。
He writes as well as you (do).他写得和你一样好。
This problem is more difficult than that one (is).这道题比那道题难。
4）条件状语从句条件状语从句由if, unless（= if not）算连词引导。
条件从句中的动词多用一般现在时表示将来。
例如：I shall go if he asks me.如果他请我，我就去。
I shan't go unless he asks me.除非他请我，否则我是不去的。
I shall go, whether he asks me or not.不管他请不请我，我都要去。
Come with me if you have time.如果你有时间请跟我来。
I want to watch a basketball match if I'm well tonight.如果今晚我好了的话，我要看一场篮球赛。
由and连接的简单句，可以用条件状语从句来改写。
例如：Run faster and you'll catch up with him.跑快点儿你就会赶上他。
=If you run faster, you'll catch up with him.如果你跑得快点，你就会赶上他。
5）结果状语从句结果状语从句由so that, so… that引导。
例如：He has lost his bike so that he can't come to school on time.（结果状语）他去了自行车，所以不能准时到校。
Your shirt were so dirty that you must wash it.（结果状语）你的衬衣这么脏，你应该把它洗洗。
注意：由so…that引导的状语从句若是表示否定意思，可以用too…to（太…而不能）来替换。
例如：She was so angry that she could not say a word.=She was too angry to say a word.她气得说不出话来。
6）让步状语从句让步状语从句一般用though（虽然）、although（虽然）、even though（即使）引导。
例如：Though/Although he tried hard, he was not successful.他虽然努力尝试，但没有成功。
He went on working though it was very late.虽然很晚了，他还在继续工作。
注意：1．汉语中的“虽然…但是…”在英语中用连词though就可以了，或单独使用but连接两个并列句也可以，但不能在一个句子中同时用这两个连词（主句前不用连词）。
例如：“虽然我很喜欢照顾我姐姐的婴儿，但她不让我干”。
这个句子我们可以用下面两种方法来表达。
Though I like looking after my sister's baby, she doesn't let me do it.I like looking after my sister's baby, but she doesn't let me do it.=though可以与yet连用，这里yet虽然意思与but相同，但yet不是连词，而是副词。
例如：Though it was cold, yet he went out without a coat.虽然很冷，但他没穿外衣就出去了。
