含义与since相同，但语气更弱，没有since正式，常翻译为“由于、鉴于”，从句说明原因，主句说明结果，主从并重。

春天，我们一起
赵中岳
相遇相知皆在夏，相知相伴需在春。

你总说毕业遥遥无期，可转眼就各奔东西。

离别苦因为眼泪苦；相伴甜，因为欢笑甜。

那年那天，稚嫩的我遇见青涩的你们，成就了我们三年绵绵的友情。

回首昨日，过去的点点滴滴都化作心中的永恒：谁推到了谁的书架，谁又与谁滚做一团，谁因成绩眼眶微红，谁又为谁双眸失神……
家、学校，两点一线，这条路我走了三年，本应熟到厌烦的行程，却因你们的陪伴每天都有放肆的欢笑。

你们如花的笑靥，似甘泉滋润我心。

这一路走来，满载欢歌笑语。

临近中考，来自各方面的压力压抑着整个班级的气氛，身后的计时牌已从三位数变作两位数，每个人都铆足了劲只为圆自己的高中梦，四面充斥着紧张的静谧。

这时他总会站出来给大家带来欢乐，即使顶着老师的惩罚，他依旧尽力的搞怪，我知道他是为大家缓解着紧张的气氛。

曾几何时，我在窗边发现班长正呆呆地发笑。

我问他在干嘛，他说：“我在练习发笑呀，因为我怕毕业的时候会哭。

”那一刻我的眼中泛起了湿意。

从那以后，我便喜欢上了独自坐在教室的角落，看着放学后空荡教室的时光，因为这寂静的校园总是在提醒我，这不是梦。

我还依稀记得为讨好语文老师，课前齐声朗读的情景，我本欲自由复习，但看着你们一个个涨红的脸，我也情不自禁地加了进去，这难道不是团结?我想我早已喜欢上这个懒懒散散却抱成一团的班级，也喜欢上了不争不吵、不喧不闹的学习生活，但你我都抵不过岁月的流逝，雨中相伴回家的身影会渐行渐远，这些年吹过的牛也终会随青春一笑了之。

离别是首歌，是声嘶力竭的苦情歌，我们用三年的时光倾力演唱，虽唱到嗓音沙哑依然曲终人散，但至少在这烂漫的春光里在万里无云的晴空下，我们一起共度这不争不吵，不喧不闹的学习时光，一遍“再见”，不负遇见。

毕业了，校服丢吗？不丢！为什么？因为太贵了！哪有多贵？三年青春，一首离歌。
