关于一些词的区别

Just有时在语序上的变化会引起语义上的不同：
Just sign here相当于this is all you have to do
Sign just here 相当于sign in this particular spot
到底有什么不同

We are both/all resdy与we all are/ We both resdy
Both/ all应位于be什么位置

Own可以作代词
A room of one’s own
注意这个习惯用法
I’m on my own相当于I’m alone
可不可以给我说说应该注意些什么

It+be+名词/代词+限定性关系从句
It was tom who helped us
It was ann that I saw
宾语是专有名词时that要比who更常用用于指其他一切宾语时that是正确的
It ‘s the manager that we want to see
It was wine that we ordered
That常用于指非人称主语
It’s speed that causes accidents,not bad roads
可以给我讲得详细点吗

关于用动词不定式替代关系从句
到底动词不定式可以替代关系代词的那种结构，不可以替代哪种结构
书上说以下这几句话有很大的区别需要注意，但我找不到他们的区别不知道要注意些什么
The first man that we saw
The man that  was seen
The firth man to be seen

The first man to see
The first man that we must see
The first man who saw

Go on till you come to the level crossing
如果省略了you come to那么就由to来代替till
Go on to the level crossing
为什么省略了you come to就由to来代替till

书上原话
He looked calm(形容词)相当于：He had a calm expression
He looked calmly (副词) at the angry crowd(looked在这里是有意识的行动)
she turned pale(形容词)相当于she became pale
He turned angrily(副词)to the man behind him(turned在这里是指有意识的行动)
The soup tased horrible(形容词)
He tased the soup suspiciously(副词)（tased是有意识的行动）
副词位于动词之后，副词前面的动词通常具有“有意识的行动”动词+副词+动词不定式
我猜得对吗，不对请告诉我副词和形容词的用法





THE的一些省略
书上原话(翻译没写)：不用在表示身体各部分或服装的各部分名称之前，这里通常用其所有格形式：
Raise your" onclick="tagshow(event)" class="t_tag">your right hand.    he took off his coat.
但应注意以下说法：
She seized the child's collar.
I patted his shoulder.
The brick hit john's face.
这三个句子也可以换一个方法来说：
She seized the child by the collar.
I patted him on the shoulder.
The brick hit john in the face用被动式表示时也可与此相似：
He was hit on the head.
He was cut in the hand.
蓝色字体部分为什么第一句不加the第二句加
红色字体部分也一样
绿色字体部分 用被动式表示时即是与什么相似
