            It is common knowledge that the Internet, often called simply Net, is the largest network of computers in the world. It connects businesses, institutions and individuals. One of its main uses is communication, and electronic mail, or e-mail, is probably the most popular use of the Internet. Although the Net is widely used by people of all ages, many adults are now concerned about is possibly harmful effects on young people.
            For example, chatting is a popular activity on the Net. Electronic chat rooms are Internet sites where people can communicate directly with one another. These chat rooms are quite popular with children. However, adults with inappropriate or illegal motives may also join chat rooms. Sometimes these adults try to arrange face-to-face meetings with unsuspecting victims. There have cases where children have been tricked by adults who pass them off as children and who give information that provokes to be entirely false.
            Another cause of worry for parents is the huge amount of information accessible to users of the Internet. Not all information on the Net is accurate, and some deliberately misleading. In addition, parents worry that children may be exposed to harmful material. For instance, there are innumerable sites where explicitly violent or pornographic scenes are shown. Moreover, many organizations maintain hate sites that present racist or politically extreme views.
            The Internet has tremendous potential for good, but it has also led to some serious questions about appropriate use. Where protection of their children is needed, parents should not hesitate to intervene. Unlimited freedom on the Net can lead to serious, sometimes dangerous, consequences.

A.there is not enough supervision on the Internet

            Homeopathy, the alternative therapy created in 1796 by Samuel Hahnemann, and now widely used all over the world, is based on the belief that the body can be stimulated to heal itself. A central principle of the “treatment” is that “like cures like”, meaning a substance that causes certain symptoms can also help to remove those symptoms. Medicines used in homeopathy are created by heavily diluting in water the substance in question and subsequently shaking the liquid vigorously. They can then be made into tablets and pills. Practitioners believe that the more a substance is diluted in this way, the greater its power to treat symptoms.
            However, in a new study, a working committee of medical experts at Australia’s National Health and Medical Research Council (NHMRC) has claimed that homeopathic medicines are only as effective as placebos at treating illness. Their research, involving the analysis of numerous reports from homeopathy interest groups and the public, concluded that there is no reliable evidence that homeopathy works. Moreover, researchers uncovered no fewer than 68 ailments that homeopathic remedies had failed to treat, including asthma, sleep disturbances, cold and flu, and arthritis.
            As a result of the findings, the NHMRC is urging health workers to inform their patients to be wary of anecdotal evidence that appears to support the effectiveness of homeopathic medicine. “It isn’t possible to tell whether a health treatment is effective or not simply by considering the experience of one individual or the beliefs of a health practitioner,” says the report. Experts believe that most illnesses said to have been cured by homeopathy would be cured by the body on its own without taking the medicine. Apparently, many illnesses are short-lived by their very nature which often leads to people believing that it is the homeopathy that cures them.
            A more serious matter is highlighted by Professor John Dwyer of the University of New South Wales. As an immunologist, he is concerned about homeopathic vaccinations on offer for diseases such as HIV, tuberculosis, and malaria, none of which he considers effective. According to Professor John Dwyer, the concept that homeopathic vaccinations are just as good as traditional vaccinations in delusion, and those who believe it are failing to protect themselves and their children.

A.‘Homeopathy kills,’ say scientists
