Toefl essay

Hi,I would be grateful if any one give me comments with my essay:

In your opinion,what is one change that should be remembered about twentieth century?

Internet is the most roleplaying incident in humans life in recent century
In my opinion,Internet has played a great role in both our social life and personal life.Thereupon I think this technology is the most significiant improvement
in this century. since Internet and it's features have changed people's life all around the world this is a thing every one should always remember
about twenieth century.

One of the advantages of this technology which is said that has made the world a village,is fast communication and broadcasting.people can
communicate with their friends and reletives who are far from them whenever they want through a fast mechanism such as mailing them,talking with them and
even seeing them by webcams.these facilities are definitely cheaper than those old system of communications such as telephone or post mailing.As a society develops and
as human's life becomes more complex,time becomes a valuable aspect of our life.Through internet we can be in touch with others in a second and we dont have to wait for a long time
to recieve a mail from your reletives or to hear from them.Moreover Internet can increase the speed of broadcasting news all round the world.you can get news of every place
of other countries with a single click.we can be aware of weather forecasts whenever we want,and the most important,news and details of a disaster such as earthquake will be soon available
in Internet and that can be a good way for obtaining helps from all around the world.

Additionally Internet has made scientifical searches and discoveries easier.since it contains a huge amount of specific informations and details of every subject,we can
solve a lot of our problems,enquiries and researches.There are a plenty of books available in some sites which perform as a library.
Intenet has even served some educational sysytems.There are a lot of schools which deliver their educational programs online.This is a great
opportunity for those who have disabilities or for any reason can not attend classes.

Above all Internet facilitate us in having a comfortable life by reducing the time wasted in rushing in trafics and streets for doing some banking affairs or for buying.
Internet enables us to buy or order whatever we want even from other countries.We can buy tickets for airplane,train,cinema,theatre easier.It also provides banking systems through which we can pay our taxes and safely move money to other acounts
without the need of carrying a large amount of money with us stressfully.

All in all in future if one want to give twenieth century a distinct feature which had changed several situations in life,that feature should be Internet.
Because of its beneficial opportunities and the comfort,the safety and the imunity it brings for us and ofcourse it's role in reducing our wasted time.
