The Internet is a part of our lives today and has become an inevitable part for most of us (try to condense your sentence here since the two points are similar, you can write: The internet has become an important part of our lives today). There are certainly many benefits it offers and drawbacks people might abuse. In this essay I shall elaborate these two things as follows. ( the two sentences above are grammatically correct, but you can improve. For example, 'there are certainly.. might abuse' is a weak connected between 2 different ideas, I would write it like this: Besides many benefits the Internet can offer, it also creates some drawbacks that affect human life...)
The benefits and contribution of Internet to human life are
unthinkablehuge and crucial. The most significant advantage of the Internet can purveyis that it becomes a library that, perhaps. the most extensive, the cheapest, and the quickest people can afford(fragment--> The most significant advantage of the Internet is that it has become the most extensive, cheapest, and quickest library for ordinary people to access). For example, people can usefind on the Internet forany kind of information and knowledge they need such as gender relationship in secluded country like Iran without going there physically. Another instance is that a student living in Amazon jungle can learn how to make American cupcake at a push of button on Youtube. That would save him hundreds of dollars without a need to visit the US, compared with the cost of using the Internet at any Internet cafe, which is about $1.
Not only internet is beneficial for everyone, from a primary school student to senior citizen, but it also brings its negatives, ranging from pornography to how to make a nuclear bomb. In the past a kid would have to prove that
they werehe was mature enough to buy an adult magazine. However, now theyhe can obtain the same adultery on the Internet with some playing truancy for this purpose. Proliferation of nuclear bomb at the hands of terrorists is brought about by the Internet technology ,with some websites detailing the simpler technique ,making the World no longer safe.
In conclusion, Internet delivers unlimited knowledge and science at no cost, which urges governments all around the World to regulate it to maximize the benefits and minimize the drawbacks
-->You gave some interesting examples to prove your points; however, I'm not quite agree with you. Not all information can be found on the Internet, especially important and secret information is often hard, even impossible, to find. You may consider to change the topic to some other issues such as: lost of personal privacy, identity theft,... I think everyone will easily agree with you in those points.
