Help needed to edit my translation
(1) Nowadays, almost everything that people are using is made rapidly by power machinery. People in ancient and medieval times did not have such machine-made products. They took long time that bored them to finish simple handwork. At that time, the energy or power for labor were dependent on one's or animals' muscles. Industrial revolution was the name given because not only did it manufactured machinery but also bring changes in people's life styles.
2) Among the changes brought by industrial revolution, the most significant ones were that
a) the invention of machinery doing handwork
b) the use of vapor and later other forms of powers took place of human's and animals' muscles
c) the adoption of system called factory
3) If the effects of industrial revolution were to be deprived from this world, we almost could not imagine what kind of world it would become. Lights, cars, aeroplanes, telephones, radios as well as televisions would disappear. Besides, most of the plentiful products on the shelves at department stores would also vanish. Those kids from poor families could no longer go to school. Instead, they would have to help out either at farm or at home. Long time ago before the invention of machinery, not only adults' labor but also that of small kids' were required to cover the needs such as food, clothing and shelter. ( here, I'd like to rephrase like this: Long time ago before the invention of machinery, both adults and small kids's labor were required to maintain the basic needs such as food, clothing and shelter. Do you think its meaning differs from the original one?)
You help is much appreciated.
have a nice day
