therefor 与so 的区别
英语中as, for, so, while等连词的用法
英语连词的用法As一．As 用作连词的用法：1. as用作连词引导时间状语从句①as与when，while都是引导时间状语从句的从属连词，含义都是"当……的时候"。
但它们有区别：用when时，从句的动作可以与主句的动作同时发生，也可以先于主句的动作发生；用while时，从句的动作为一过程，主句动作与从句动作同时进行或在从句动作过程中发生；用as时，主句和从句的动作同时发生，具有延续的含义。
例如：(1)It was snowing when he arrived at the construction site.他到达工地时，天正在下雪。
(2)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。
②when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。
如:When he was at college, he could speak several foreign languages.When the clock struck twelve, all the lights in the street went out.③while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。
如:Work while you work. Play while you play.④但属下列情形时,只用as, 而不用when或while。
A) 用于表示同一个人的两种动作交替进行,指"一边……,一边……"。
如:The girl dances as she sings on the stage.He looked behind from time to time as he went forward.B)表示两个同步发展的动作或行为,译为"随着……"。
so和such用法小结
so和such用法小结一,so的常见用法1.当so作副词,修饰形容词或副词时，表示程度,意为”这么","那么".如:Don' t be so silly。
别那么傻.He ran so fast.他跑得那么快.2。
如果so后无形容词,则so不能与名词连用.如:I’ ve never seen so tall a child(=such a tall child)。
我从未见过个儿那么高的小孩.切不可以说”He is so a child."但是，so little,so much可与不可数名词连用,so few,so many可与复数名词连用如:Tom ate so much food a meal。
汤姆一餐吃了那么多的食物。
There’ re so few people in the hall。
大厅里的人很少。
3.So…that 意为"如此……以至于……”，是一个常见句型,也是中考常考的句型。
如：J ane’ s leg was so painful that she couldn' t move at all.简的腿那么疼,以至于根本动不了.该句型还可以转换成”So + a dj.+ a/an+名词”结构。
如:Mike is so clever a boy that all like him。
麦克这么聪明，大家都喜欢他.so that意为”以便",”为的是"，引导目的状语从句(该目的状语通常用情态动词作谓语）如：They can help you to compare two different products so that you can buy the one you really like。
他们能帮助你比较两种不同的产品，以便你能买到自己真正喜欢的。
so that从句还可表示结果，意为"因此”, 如：His pen is missing，so that he hasn’ t done his homework。
some和much的用法区别
some和much的用法区别一、使用场景及意义的区别1.1 "Some"的用法在英语中，"some"通常用来表示一个数量不确定或未指定的事物。
它可以用于肯定句和疑问句，并且强调的是多少而不是精确数量。
在肯定句中，"some"表示存在某种东西或某个数量的事物。
例如：- I bought some apples at the grocery store.（我在杂货店买了一些苹果。
）- Can you give me some advice on how to study for exams?（你能给我一些建议，告诉我如何备考吗？）- She made some friends during her trip to Europe.（她在去欧洲旅行期间交了一些朋友。
）在疑问句中，"some"用于委婉地请求或询问对方是否可以提供某种东西或某个数量的事物。
例如：- Could you lend me some money until I get paid?（你能借给我点钱直到我拿到工资吗？）- Would you like some help with your luggage?（你需要帮忙搬运行李吗？）- Is there any chance we can meet for dinner tonight? I have some news to share.（今晚有没有可能我们见面共进晚餐呢？我有一些消息要分享。
）1.2 "Much"的用法与“some”相比，“much”则用于表示数量较大或具体数目的事物。
在许多情况下，它常常与否定词连用，例如“not much”、“hardly any”等，来强调缺乏或不足。
在肯定句中，"much"可以单独使用，但通常和表示量词（如“so”，“too”，“very”）连用以加强程度。
英语语法：状语从句八大类型的区分以及知识点讲解
英语语法：状语从句八大类型的区分以及知识点讲解NO.1 副词作状语(1)句子副词：句子副词用于修饰句子(而不是修饰某个单个的词)，反映说话人的观点和看法。

但有些句子副词也可以出现句中。
eg：He smiled nastily. He evidently knew something I didn't. 他发出狞笑，他显然知道一些我所不知道的事。
有的句子也可用作其他种类的副词，不过这往往会导致位置和语义的变化：Clearly he didn't say so. 显然他没有这样说。
(句子副词)He didn't say so clearly. 他说得没有那么清楚。
(方式副词)(2)起连词作用的副词连接副词就是连接词，如besides，meanwhile，then, therefore, thus, However,Otherwise, so, yet 等。

such和so的用法
such和so都可以用来表示程度，意思是“如此；这样”，但用法却不相同。
1．such是形容词，用来修饰名词，名词前有无形容词都可以；so是副词，用来修饰形容词或副词，形容词后可以省略名词。
例如：He is such a（big）fool．他是个（大）傻瓜。
He is so foolish（a man）．他是如此愚蠢（的一个人）。
2．单数名词前有不定冠词与形容词时，so和such的位置不同。
前者为“so＋形容词＋冠词＋名词”，后者为“such＋冠词＋形容词＋名词”。
例如：I know such a clever boy．我认识如此聪明的一个男孩。
I know so clever a boy．我认识如此聪明的一个男孩。
3．so后即使有形容词，也不能修饰复数名词或不数名词，而such则可以。
例如： They are such useful books．它们是如此有用的书。
He gave us such good food．他给了我们这么好的食物。
4．名词前有表示“多、少”意义的many，much，few，little等修饰词时，要用so，不用such。
例如：There are so many flowers in our school garden．我们学校的花园里有那么多的花。
You'll find English a bridge to so much knowledge．你会发现英语是通向如此丰富知识的桥梁。
I have so little money that I can't lend you any．我的钱很少，不能借给你。
5．当little表示“小”的意思修饰可数名词时，其前只能用such，不能用so。
例如：I have never seen such little sheep before．我以前从没见过这么小的绵羊。
such..that和so..that的区别和用法such…that…与so…that…都可以用来引导结果状语从句，意为“如此……以致……”。
