Theimplication implicit in the drawing can be elaborated as follows. On the onehand, the Internet has provided us with great convenience and efficiency. Forexample, we can get knowledge about nearly all aspects on the Internet withonly several keyboard commands and a few clicks of the mouse through searchengines. On the other hand, with an explosive amount of information on theInternet it can be difficult to tell good information from bad. For example,teenagers and adolescents may mistake the bad information online as good, theresult of which can be rather devastating. In addition, some dirty information suchas obscene and violent contents on the net may exert negative impacts onpeople.
Based on what isanalyzed above, on the one hand, it is important for us to take full advantageof Internet to enhance our efficiency and save our time. On the other hand,effective steps should be taken to educate people to avoid and eludeinappropriate and even wrong data online so as not to be misguided. Only inthis way can the net better serve for our life, study and work。
