曹老师，我经常听到欧美人说类似的句子：You can scream all you want.这个all是副词还是代词，有人认为是代词，我也想这样认为，但是问题是all做的成分是哪个，难道是宾语吗，虽然scream有及物和不及物动词的词性，但是这个地方应该用的是不及物动词吧，因为你喊的内容all并没有指代啊。另外如果all是代词的话，后面的you want很容易可以解释为关系分句省略that了，但是如果是副词呢。

维基百科词典（Wikdictionary）是这样解释的：

Adverb

all you want (not comparable)

1. As much as you like; used to emphasize the preceding verb or verbal clause.

Scream all you want, but it is not going to change the fact that the museum will be closed for the entire month.

它这给的词性标注的是adverb，＝as much as you like

还有这种句子，总不能去解释为all是副词吧？You can critique it all you want and it won't change a thing. It's over.

或者是you can pretend to be innocent all you want.

另外Read as much as you could这个much是代词还是副词？
