1型文法的意思
1型文法
1型文法也叫上下文有关文法,此文法对应于线性有界自动机.它是在0型文法的基础上每一个α→β,都有|β|>=|α|.这里的|β|表示的是β的长度.
注意:虽然要求|β|>=|α|,但有一特例:α→ε也满足1型文法.
如有A->Ba则|β|=2,|α|=1符合1型文法要求.反之,如aA->a,则不符合1型文法.

就按这几个大块写就行

// with是介词,后面接名词,你用了三个形容词.
// 并列句放在后面在连接词前大多没有逗号
During the progress,we should not only make sure that most civilians acquire the ability to apply for Putonghua,but also respect the values of dialects.
// during the progress."during the process" is better.
// apply for 申请.申请普通话?
Spreading pronghorn is not to eliminate dialect,but to help people gain universal language of our nation while using their dialect and apply Putonghua in formal occasions.
// pronghorn?小女子才疏学浅,百度翻译为“叉角羚”.
So far,each ethnic has made great contributions to Chinese traditional culture in its own way,and all these traditional indigenous cultures are precious elements of Chinese culture.

副词是用来修饰动词的!这对英语也适用的啊!slowly是slow的副词形式 slowly修饰open 自然正确啊
形容词(包括副词)
形容词表示某一事物或的特征,副词表示某一动作的特征.
形容词和副词只有两种形式:原形和+er.
形容词修饰名词,说明事物或人的性质或特征.通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面.
1) 直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语.例如:hot 热的.
2) 叙述形容词只能作表语,所以又称为表语形容词.这类形容词没有级的变化,也不可用程度副词修饰.大多数以a开头的形容词都属于这一类.例如:afraid 害怕的.
   (错) He is an ill man.
   (对) The man is ill.
   (错) She is an afraid girl.
   (对) The girl is afraid.
这类词还有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake 等.
形容词作定语修饰名词时,要放在名词的前边.但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后
大部分形容词加-ly可构成副词.但 friendly,deadly,lovely,lonely,likely,lively,  ugly,brotherly,仍为形容词.
副词主要用来修饰动词,形容词,副词或其他结构.
一、副词的位置:
1) 在动词之前.
2) 在be动词、助动词之后.
3) 多个助动词时,副词一般放在第一个助动词后.
注意:
a.大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡.
   We could see very clearly a strange light ahead of us.
b.方式副词well,badly糟、坏,hard等只放在句尾.
   He speaks English well.
二、副词的排列顺序:
1) 时间,地点副词,小单位的在前,大单位在后.
2) 方式副词,短的在前,长的在后,并用and或but等连词连接.
Please write slowly and carefully.
3) 多个不同副词排列:程度+地点+方式+时间副词.
注意:副词very 可以修饰形容词,但不能修饰动词.
