看了他人的回答，怕耽误你的学习，给你正确的答案。表示很，太的时候，too和so意思是一样的，只是表达方式不一样。她太年轻了。She is too young.和She is so young.含义基本相同。但是在这两个句子后面如果接上短语或从句，表达的意思就不同了。too...to太……以至于不（能）She is too young to go swiming alone.她太小了，不能独自去。so ... as (not) to ...太……以至于(不）能She is so young as not to go swimming alone.她太小了，不能独自去游泳。She is so brave as to go swimming alone.她胆大得一个人去游泳。so ... that从句：太……以至于She is so young that she can't go swimming alone.She is so brave that she she wants to go swimming alone.布置你现在明白没有？前面那些回答说：so放在句首，too放在句尾，这种结构是有的，但表达的意思是“也”。如：I am a worker. So is he. I am a worker. He is a worker, too.
