　　Disadvantages

　　1.网络

　　Take the most popular form of recreation among younger people---computer games for example.It must be admitted that there are all sorts of games catering to people of different ages and gender and some even claim to be educational.But the truth remains that people are attracted to games mainly because of the graphic and audio effects.Swiftly abandoned are those games that demand too much cerebral activities because games are meant to be relaxing and entertaining.Thus， to play most games one only has to use his reflects; there is hardly any thinking involved， let alone creative thinking.

　　2.However，the other side of the coin voices its strong opposition， saying that the Internet has many weaknesses.For one thing， it can easily lead to psychological problems.An Internet-addicted person tends to be isolated， self-centered and unsociable.犯罪For another， there is a sharp rise in the number of cyber crimes.More and more financial crimes such as money laundering are committed via the Internet .In addition， it also has negative impacts on young people because there are a lot of obscene and violent contents on line.

　　3.犯罪

　　Online commerce does come with a certain amount of risk， the biggest of which is identity theft.

　　6.情感关系

　　Graver still is the alienation and estrangement between people caused by the extensive use of machinery.We gradually lose sight of the connection between people when most of our daily contacts are with a machine.

　　7.TV does an even better job at diminishing our creativity.

　　8.看电视的被动型

　　When people watch TV， they just passively take in what is presented on the screen.Their eyes are riveted on the screen; their minds go

　　blank.

　　9.Besides， there is no time for them to pause to reflect and think.Gradually， the habit of passively taking in everything without thinking is reinforced.

　　10.The appeal of TV lies in the fact that it asks almost nothing of its audience.

　　11.Contrary to what people expect， TV alienates family members by absorbing their time and attention which can otherwise be given to each other.Superficially， the parents and children who sit in front of a TV are supposed to spend some quality time together.

　　11.看电视的被动型

　　But in fact， they are glued to the screen， receiving passively what is offered by the producers.There is no lively discussions， no exchange of views， but only occasional fights over which channel to watch.The time spent watching TV could have been used far more effectively to communicate with each other and strengthen family ties.

　　15.People's social life is also affected by the advent of television.Before the age of television， people used to socialize more in the community.After dinner， men would get together to discuss work and politics while women exchanged gossips.Close community ties often can't withstand the onslaught of TV programs， which induces people to shut the door， sit on the couch and stare at the screen.People become less likely to play a game of chess or basketball with their neighbors.TV has robbed them of other more worthwhile activities.

　　16.飞机

　　However， others who think this trend is a negative development say it may give rise to a series of problems.Firstly， the worldwide increase in air travel poses a serious threat to the global climate.Carbon dioxide emitted by planes is the main greenhouse gas，which is regarded as the major reason for global warming.

　　18.Thirdly， traveling by air has a risk.Each plane crash is a terrible disaster and it often causes great losses both to the country and to the victims’ families.

　　19.科技弊端

　　It must be realized that in the process of solving problems， scientists also create problems， the solutions of which are often beyond their reach.To do them justice， it is not always possible to predict the results and bring everything under control.For example， after setting up a nuclear power plant， scientists are unable to find an ideal way to treat nuclear waste， nor are they able to eliminate the threat posed by radio activity.Thus in many fields， science and technology is far from providing perfect solutions.
