The Effects of an Invention or Innovation in Modern Life. (1)

　　In the ancient time, when the weather was hot, we used fan to let us feel more comfortable by vibrating our own hands. But in the modern life now, there is an great inversion (invention) that has revolutionized the way we behave today which is called "air conditioner." It is so easy and convenient that we just need to insert the connector and click some buttons, then the cold air will come out of the machine. Air conditioners have been existed in everywhere, such as homesites, schools, and skyscrapers. We cannot live and feel annoyed without air conditioners especially in summer. Beside the cold air, there are many modes that we can choose for what we need. For instant (instance), we can select [[the eliminates wet mode]]==>one that gets rid of moisture when the weather is wet or one that would give us a good dream by turning to the comfortable sleeping mode.
