In the early nineteenth century, people began to use gas (gaslight), butthe gas pipeline supply by a leak or blockage, very easy to have an accident,people for illumination of reform, very ardent.In fact, Edison for himself setthe mission impossible: in addition to improve lighting, but also of ThomasEdison electric light Create a set of power supply system.And he and the dreamLuoYuan buddies, sleepless do 1600 repeatedly heat-resistant material and morethan 600 plant fiber experiment, only produced the first carbon wire bulb, can aburning 45 hours.Later he more on this basis, the method of continuousimprovement manufacture can ignite 12 hours finally came out with the ZhuSibulbs.The 19th century the 1980s, Edison electric light career succeeded, thissuccess than any previous achievements brought him reputation.In the 1980s,before he had little mistake, intermediate later, although he has made greatachievements, but also common occurance of failure.Edison's most not commendableactions is one of his criticism alternating current, say it has side effects,likely cause of death and injury, but he did not add details.So somebody said,"as he such a mess out many inventions that people about others' new inventionsaurday attack, this is very contradictory things." He opposes the use ofalternating current and direct current, so the approve a fierce debate andstubborn in failure.In this respect, reflects the Edison became a celebrityafter the stubbornness of started to foster old-fashioned shortcomings.

What is my favorite invention?
We knew there had been many inventions at the last century, for example,electric light bulb, telephone, phonograph, mimeograph machine, automobile,airplane, atomic weapon, computer and so on. What is my favorite invention?
Personally, my favorite invention should be computer. In the old days, manyscientists took much time to calculate and deal with research data, so theeffective time in doing research was relatively shortened. For millions of timesof calculating per second by computer, the researchers may have enough time tostudy more important issues. The processing of experiment results became verysimple and easy. Aren’t those all evidences that the computer is one of thegreatest inventions in the last century, are those?

Today I'm glad to be here to talk about what I'd like to invent - a chairthat's good for students' health. It will be made of wood. There will be twosensors in it -- one on the seat, and the other on the back of the chair. Whenthe student doesn't sit straight, the chair will remind him .If he sits on thechair for over one hour ,it will make a noise. It won't stop until the studentstands 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?
