Computer is a very essential things in our life.
During the past 10 years, the use of computers in education has increased dramatically and a wide range of educational computer programmes are now widely available for individual and classroom use. However, there has been very little research reported on the effectiveness of such use. The purpose of the present study was therefore to ascertain the effectiveness of using computer-assisted instruction as compared to traditional classroom instruction in an EAP writing class. The findings clearly suggest that the inclusion of web-based materials in EAP writing courses for post-graduate students from East-Asia on an English language preparation course is effective. Further research is needed, however, before the use of such materials can be recommended for all students in all subject areas at all levels. In conclusion, therefore, it can be seen that millions of people continue to be affected by water-related problems and, contrary to popular belief, future water supplies are not inexhaustible. So the situation is very serious, especially in view of the UN estimates of demand. Although projects to provide ever-increasing supplies of water indicate that a growing number of countries are aware of the present problems and of those to come, these more often than not are highly expensive and not very practical - and very time-consuming when time is a commodity in short supply. So, while research in these areas is important, the eventual solution would definitely appear to be worldwide conservation and pollution control - in other words, a greater respect for our most valuable natural resource.
Altogether, it seems that we cannot accept without question the dramatic increase in recorded crime as corresponding to a real increase in victimization of the same proportions. But, however good it would be to explain away all, or even most, of the increase as an artefact of recording changes, this cannot be shown to be the case. We can plausibly infer that crime has been increasing in the last two
to three decades, presenting a problem for explanation and policy. However there is lots of things to do in our life, that would not be possibe by doing ownself. Thats the reason we need computer.
