14、o fast to be.是too.to.结构,该结构意为“太以致不,太而不能”。其中too是副词,用来修饰形容词/副词,to是动词不定式符号。The boy is too young to understand the story.这个男孩太小,理解不了这个故事。 思维拓展使用too.to.结构时应注意:(1)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的动词是及物动词时,不定式中的动词后不能跟宾语。Tom spoke too quickly for us to understand.汤姆说话太快了,我们听不懂。(2)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的
