最新陕西旅游版四下unit4 what do you do课件

宁亚喊她，蕊敏，你去哪？她头也不抬地回，去死。 因为心里憋闷，杨蕊敏决定去护城河边溜达。她总觉得数学成绩不好跟她小时候摔破过脑袋有关，要不就是自己资质太差。转来转去，才发现后面有个人跟着。杨蕊敏心下一惊，想八成是遇上劫匪了吧？怎么办，这僻静的地方，真是叫天天不应叫地地不灵。
她只好抱住书包往前面使劲地跑，还不忘回头看看。因为心慌，她一个踉跄摔在地上。书包里零碎的东西散了一地。正在无措的时候，后面男生撵了上来。 你想干吗？蕊敏清了清声音，故作勇敢地说。
你们很少联络，在这长长的一生中，你门相聚的时光也许只有几万分之一，但是在彼此的心中都保留了一份惦念，一份嘱咐，就算他去到天涯海角，就算过了许多许多年，就算再见面时，早已是人非物亦非了，你仍然会那样深刻的记着这样一个人，这已经足够了。
生活有时候平静的会像一口枯井，也许你也会掉进这口枯井里去，也许你没有什么天荒地老、海枯石烂的爱情，也许华发早生、满鬓苍白，但是有了这样的一位朋友，在你的生命中就会有些许涟漪，些许色彩，你想着他。默默的记起他，也许此生此世都不会忘记了。
I 'm so happy to teach you today , bye~
