Will you please give the dictionary to Jane I'll give it to

如： I didn't recognize him until he took off his sunglasses. recognize 为短暂性的词。 你说的意思不同性质的动词句意不同应该是指since吧 It's three years since he came here. (come 非延续性动词， 他来这儿有三年了) It's three years since he lived here. (live 延续性动词，表示动作从这一刻结束算起， 他不在这儿住有三年了) 明白了吗？
