In THE first place, we have de THE cellphone, I think that this one is the most used today, in ON THE one hand, it turns out to be extremely useful as a communication and working tool, but on the other hand, it turns out to be a very large distraction and loses its true value.  

 

The next one is the internet, I think this one is the most important because we have internet everywhere, actually, anyone who doesn't have access to the Internet is lost and out of this new modern world. 

 

This THESE two inventions have helped us to improve our communication around the world, the cellphone and the internet are two of the most important inventions in the history of mankind.

 

Now, the car and the light. 

 

The light improves our visibility, which allows us to see and know many more places, and obviously, when IT is dark and we can’t see, we have light. 

 

The car, is by itself awesome, because regardless of the technology and advances it has year after year, its main function (transportation) is a brilliant invention. /CHECKED. Maritza. Well done in general, just pay attention to some words that are repeated, look for synonyms. 

 

At the beginning of the century, the first invention that was made was the light bulb, invented by Thomas Alba Edison, with the passage of time this invention has evolved into led lights that help to save energy.

The internet, a practical invention for leisure, schools, all kinds of research and also for those seeking recipes for fitness and healthy eating habits. Even the internet helps people to find jobs, in other parts of the world, and keep the families in touch with the different ways of communications, that I will explain to you next.

With all these technological advances, the cellphone has served to have an easier and faster communication. It is amazing to see the capacity that those small devices can have, storing all kinds of apps, Facebook is a classic example of this, a social media platform that became out of control throughout the years and as all things that get out of control there are repercussions, a good example of this is crime rates and privacy problems, these types of problems can contribute to stress and as a consequence of that, people that don’t sleep enough and have bad health.

The automobile has served many people for transportation, although they are not good for the environment, they do make life a lot easier and give us the possibility to perhaps maintain a friendship with people who live far away, discover new interests and forms of entertainment outside our town, go to work, and get the most out of our free time. /CHECKED. Maritza. Well done! My only suggestion would be to improve the punctuation, use semicolons ( ; ) in combination with commas and periods.

The definitive inventor of the automobile isn’t clear, an example of this is Nicolas Joseph Cugnot who is widely credited with building the first full-scale self-propelled mechanical vehicle or car in about 1769; he created a steam-powered tricycle but most say it was the Benz Patent-Motorwagen, first built in 1885 was the first automobile in the world whom in the actually is Mercedes-benz  which is a popular luxury car company, independent mind who invented the first automobile I think now the the automobile is an essential part of the life, there are people who have to work several kilometers away from home or products that have to be transported from the factory to the storage of the stores those are who are really benefiting of the invention of the automobile. 

But there are always have two faces of the same coin, whit WITH lower prices and more people interested in acquiring an automobile, the number of automobiles drastically increased the problems like the pollution or the traffic where you lose WASTE some time. /CHECKED. Maritza. 
Work on punctuation and look for synonyms to avoid repetition.
