much too和too much的用法区分
区别：
意义不同。too much ”太多“，much too “非常”。
如：a. She have too much homework to do.（她有太多的家庭作业要做。）
b. He is much too busy doing homework to play basketball with you.（他正在忙着做家庭作业，不能和你一起去打篮球了。）
2. 用法不同。too much 常作为形容词性修饰名词，而 much too 常作为副词词性修饰形容词或副词。
如：a. She have too much homework to do.（句中 too much 作为形容词性修饰名词 homework）
b. He is much too busy doing homework to play basketball with you.（句中 much too 作为副词词性修饰形容词 busy）
拓展：
too much “太多”，too many “太多。二者虽意义相同，但所修饰名词有所区别：too much 修饰不可数名词，too many 修饰可数名词复数。
much too和too much的区别在于最后的词，much too强调的too“太”，后跟形容词，too much强调的是much“很多的”，后跟名词
