Hi, everyone. As we all know,many great inventions have brought great changes to our life. I think we students can also invent something.
大家好！我们都知道,许多伟大的发明给我们的生活带来了巨大的变化。我认为我们学生也可以发明一些东西。
Today I"m glad to be here to talk about what I"d like to invent - a chair that"s good for students" health. It will be made of wood. There will be two sensors in it -- one on the seat, and the other on the back of the chair. When the student doesn"t sit straight, the chair will remind him .If he sits on the chair for over one hour ,it will make a noise. It won"t stop until the student stands up and leaves.
今天我很高兴到这里来谈论我想发明——一把椅子,对学生的健康有好处。这将是用木头做的。将会有两个传感器，一个在椅子上，另一个在椅子后背。当学生不坐直,椅子会提醒他。如果他坐在椅子上超过一个小时,这将发出噪音。它不会停止,直到学生站起来,离开了。
It will be a useful invention, won"t it ?
这将是一个有用的发明,不是吗?
