Сама писала подобное сочинение некоторое время назад, тема очень похожа "Modern conveniences have changed our life", в принципе, под твою тему почти идеально подходит. This is obvious that our life has changed since the modern conveniences appeared. Nowadays, we can't imagine our life without such things as computers, TV, cell phones, microvawe ovens, refrigerators, etc. The advantages of modern conveniences are evident. Firstly, they are very labour-saving. For example, such things as microwave ovens, washing machines and vacuum cleaners really make our life easier. Secondly, they save a lot of free time for their owners. And finally, some of the mod cons, for example TV, Internet and computers, are very good means of entertainment. On the other hand, some disadvantages exist. First of all, almost all of the mod cons make us lazier. In addition, we become less intelligent when some gadgets do the "brain tasks" instead of us. Finally, a harmful radiation undouptedly hurts our health. To sum up, we can't deny that modern conveniences have improved our life, but in the same time they have several disadvantages as well, so we must be careful using them. Можешь немного изменить и подогнать под свою тему, но идея такая же.
