太兴奋导致英文

可以。但最好是He was so excited that he couln't fall asleep.而你自己写的那一句是以致不能睡觉，不是睡不着觉。

The children are too excited to sleep one night

我觉得可以 去掉第二个he会更好

他太兴奋了，以至于不想活动:He was so excited that he didn't want to move重点词汇释义兴奋exciting; be excited; sweep off one's foot; hectic以至于see also 以至活动move about; exercise; shaky; unsteady
