两者均表示“太……”
而too much的主要词为much
much too主要词为too
比如：much better→too much better
too big→much too big
too much
在这个短语中,中心词是much,too修饰much,用来加强语气.
（1）much作形容词时,too much可用在不可数名词前,表示太多.如：
I drank too much wine last night.
我昨天晚上喝酒太多.
（2）作为短语起名词作用.后面可加of短语,也可单独使用.如:
You have given me too much.
你给我的太多了.
You gave me too much of the paper.
你给我的纸张太多了.
（3）作为副词短语,修饰动词性很强的过去分词.在正式的文体中用too much比用too好.如：
I’m not too much bothered by his criticism.
我并不因为他的批评而感到不高兴.
（4）放在句末修饰动词.如：
He talked too much.
他讲得太多了.
（5）不能直接修饰形容词或副词（因为much不能这样用）.如,
不能说：This one is too much big.
（6）一般不放在be后面作名词主语的表语.如,
不能说：The noise was too much.
应改为：There was too much noise.
3． much too
（1）much可以修饰“too+形容词或副词的原级”,用来加强语气.如：
This one is much too big.
这个大得太多了.
You are going much too fast.
你走得实在太快了.
（2）much一般不能放在too many或too few前.如,
不能说：We’ve got much too many eggs and much too few eggcups.
应改为：We’ve got far too many eggs and far too few eggcups.
我们的鸡蛋太多了,而蛋杯太少了.
