针对现在学生坐姿不正确，玩电脑、看电视时间过长的现状，你想发明一种特别的椅子来解决这些问题。假设下周你们学校的英语俱乐部将举行英语演讲比赛，主题为“I want to invent ...”。请你根据下面的要点提示用英语写一篇演讲稿为比赛作准备。
要点提示：
1. 材料是木头；
2. 座位与靠背安装有感应器(sensor)。没有坐直的时候，椅子会提醒学生；坐在椅子上超过一小时，椅子也会发出噪音。
要求：
1. 演讲稿需包括以上要点提示，也可适当增加内容；
2. 80词左右，演讲稿的开头和结尾已给出，不计入总词数。
I want to invent a chair
Hi, everyone. As we all know, many great inventions have brought great changes to our life. I think we students can also invent something.
