as soon as 一.就 她一到我就把字典给她.until 用在肯定句的时候,其前面一般都是延续性动词.如：Let's wait until the rain stops.wait 为延续性动词He continued working until he died.而该句give 是个短暂性动词,...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？
