下面那位语法都错了。。but 和 because 是连接词不能作为一个句子的开头。。我帮你纯手打
I am in the 6th grade and am going to a new middle school soon. I am sad because I have to say goodbye to the teachers and friends I have known for six years, but I am also excited to learn new things and meet new friends. I know that middle school will be much harder than elementary school, so I will work hard and try my best.
