又是狗的交配时期

我又来抱佛脚了！！哈哈！！温习到凌晨。。。屋外的狗又来吵啦。。。对。。。交配时期又来啦。。。
记得去年的这个时期，我真的让这群狗折磨到很惨。。。我已经因为考试而睡不着了，它们还要三更半夜来吵醒我，搞到我真的是没得睡。那段日子真的想起来都觉得很害怕。我是第一次被考试折磨，真的是很惨！！那些今年考试的朋友们，努力读书吧，有读就一定会做的，要有信心！！加油！！

有话要说

我又弄多一个新的BLOG。这个BLOＧ被弄出来的原因是宝宁说应该要让大家看看我在Ｐｅｎａｎｇ是怎样的ｗｏｒ．．．所以我会尽量在这个新ｂｌｏｇ里面多放一些之前在ｐｅｎａｎｇ拍的一些照片。如果我有时间的话，我会常常ｐｏｓｔ一些新的东西的．．可是我觉得不大可能．．．所以如果我以后ｐｏｓｔ一些很久以前的照片请多原谅哈哈。
至于我那个百年都没有碰一次的久ｂｌｏｇ，我应该没啥时间理它了．．
