　　MynameisLihua.IwasborninGuangZhouinFebruary1988怎么合成一句的，因为是五句话作文.谢谢。还有骑士那里是2001到2007在广州第六中学上学，但合成一句我不知道怎么写。。麻烦了点不好意思...

　　额，其实用定语从句MynameisLihua,whowasborninGuangZhouonFebruary1988.语法上来讲好像也没有错，但是这样讲怪怪的。要不就MynameisLihuaandIwasborninGuangZhouonFebruary1988……？IstudiedatGuangMingPrimarySchoolduring1995to2001andGuangzhouSixthSecondarySchoolfrom2001to2007.你们中学的名字的翻译我不太确定。这样子简单一点可以吗？再就是IstudiedatGuangMingPrimarySchoolduring1995to2001，afterwhichIenteredGuangzhouSixthSecondarySchoolandstudiedtherefrom2001to2007.还有应该是haveatalentfor，我刚才给改错了，抱歉……
