all of和 all的用法分别是什么
all of后面只接代词用来指代文中的对象。
例句：I haven't used my French for years and have forgotten almost all of it.
我的法语丢了好几年了，都忘得差不多了。
all则有九种用法，列举如下：
1、作为形容词，all必须放在一切定语、限定词甚至冠词之前。
例：all the world 全世界
2、可以作为不定代词，表示“一切（事物）”。但是通常只能当后面接着有一个以that引入的定语从句（但that可以省略）对其范围加以限定时才可以这样用。
例：All microevolution needs to work is a loss of genetic information.
只消遗传信息有丢失，微观进化就能起作用。
3、all (the) people或all (the) things如果后面不附上补充的限定修饰成分，就很少使用，而代之以everybody (everyone) 或everything。
例：All the people in the room are ready.
房间里人人都准备好了。
4、all往往隐含“这就是全部，再多就没有了”的负面限制意义。
例：Is that all he said?
他就说了这些，没说别的吗？
5、all... not...局部否定。all与否定在一起，是all被否定而变成了“只有一部分”，不是否定被all所支配而变成“全盘否定”。
例：All that glitters is not gold.
发光的不全是金子。
6、all作为形容词表示“整个（某空间或时间）”时往往跑到介词之前，变成了类似副词。
例：all over the world 在全世界
7、all可以同人称代词主语连用。在古英语中，它可以放在这个主语之前，成为句子开头第一个单词。
例如：All we like sheep have gone astray.
我们大家全都像羊一样迷了路。
8、all修饰宾语时，如果宾语是代词，all可以放在代词后面，也可以放在代词前面，当中加上of。但是如果宾语是名词，则只能用all of形式（如果名词是定指的，of可以省略）。
例：They played all of/all the Beethoven concertos. 他们演奏了贝多芬的全部协奏曲。
9、all后面有数词时，虽然是指这个数目的全部，但通常不加the。
例：All five(*all the five) were lost.
五个都损失了。
