you can't sleep too long.老大这里的sleep too long该如何理解?sleep为动词long为形容词
如果后面有接宾语倒是没问题,但是后面没有跟宾语,这种情况下不是该是sleep+to be +long的不定式结构?何解?小哥.

Answer 1

sleep可以及物,也可不及物,意思稍有差别.但这里应该是不及物的,因为不及物的sleep才是睡觉的“睡”.
但这里的long却是副词.long可形容词,可副词,但做形容词时,只有长度的感觉；只有副词的时候,才有时间长度的概念.
long =adv.= During or for an extended period of time; Beyond a given boundary,limit,or goal; For or throughout a specified period;At a point of time distant from that referred to.
very是副词,修饰副词long,没有问题；verb + adv = perfect grammar!
