Prototype of  Kamen's power machines was a significant innovation for most of the developing world. First of all, some developing region like Africa, the Middle East and the southeast Asia were in darkness at that time, while the advanced countries were in lightness, which was unfair. What's more, if lightbulb could be used in a simple and cheap way, people would have more time to make a living to improve their living standard; at the same time, Famine would be reduced.  Last but not least, bulb production and sale would stimulate the development of economy and industrialization process; in addition, many people could get a job. In a word, as far as I am concerned, in the future, in order to make our country more advanced, we should encourage and invest more money into the inventions such as the bulb.

This is a story from An Upheaval written by Chekhov narrated that a governess was searched rudely by her house misstress and then she left. Oneday,she returned home finding her room was rummaged by mistress because of a missing brooch.She was considering going to courts for clarification when she was invited to dinner. She felt ashamed in the dinner and considered whether she should leave or not.The master of house admited his stealing and lastly Mashenka left. It revealed something meaningful deeply that although some people were kind, but they suffered from the oppression of the evil people who had higher social status.The plot was developed chronologically. The upheaval happened only in half a day, which was out of Mashenka's imagination.The characters were static, Mashenka was kind, but the misstress was evil.And the host was coward.The writter used a colloquial language and  he descibed the unfair society by means of a kind of realistic and objective way.
