i want a short speech about the usefulness of the internet and its hidden dangers?, Please help if it possible ;)

Bonsoir, voici un petit texte sur les possibles dangers d'internet traduit.

The main risks to know when you surt to internet are : the involuntary exhibition in shocking images, the meetings with bad persons, the cyber-harassing (insults, mockeries, publication of personnal photos ) and the publication of the personal information (name, address, phone number).

Voilà, en espérant t'avoir aider :)
