Nowadays,many people spend much time watching television.It can't be denied that since television was invented,it has changed our life in many ways ,and brought us many advantages as well as disadvantages.

Television plays an important role in our daily life.It's very informative.Through television,we can get the latest information easily and rapidly without leaving home.We can learn more and more about the world we live and see many interesting things.Our knowledge is broadened in many ways.

Secondly,televiosin helps us to enrich our spiritual lives.In particular,we can learn the language we like such as English,Chinese,France,Spanish,Japanese.....through language programs.We can be good and clever at doing jobs,making cake,cooking,arranging flowers through practical course which is taught on television.

And watching is an enjoyable way to relax.After a hard-working day,it's so comfortable and fun to sit at the armchair and see a movie or watch a comedy program.There are also educational programs on television,so children can learn a lot from these programs.

On the other hand,televiosion has some disadvantages.It has negative effects,especially for children.Some movies contain violence or crime.Therfore,the evil influence of televison on the young generation is inevitable.It encourages them to commit crime,or make children grow up to be violent adults.

What's more,watching television too much makes us passive.When watching TV,our brains don't need to work.Therefore,our brains become lazier.Watching TV too much is also bad for our eyes.This is the main cause that leads to short-sightened.

All things considered,everything has two sides,advantages and disadvantages.Television will be useful to us of only we know how to use it sensibly.

Nowadays, teamwork is an essential element of the society. We all work with people everyday. A co-worker is a person with whom we work closely and share tasks. In my opinion, the important characteristics of a co-worker should be as followed.First of all, an important character of a co-worker should be reliability. As we often have to encounter a lot of problems at work, it is a good thing to work with someone that we can always count on. A reliable co-worker can help us with problems that we cannot solve by ourselves. Also, if we happen to be absent from work, a reliable co-worker can always backup what we have been working on and make correct decisions even without us.
Last of all, another important character of a co-worker should be responsibility. Indeed, no one would want an irresponsible person as his or her co-worker. It would be a nightmare if your co-worker does not do anything and leave everything for you to finish. On the other hand, a responsible co-worker not only do his own part of work, but also, as soon he finishes his own, helps you finish yours, which in turn enhances the efficiency of the work. A responsible co-worker can help others work more efficiently by giving others aid in addition to getting their part of job done.To summarize, as I have stated above, a good co-worker should be reliable and responsible. A co-worker that possesses these characteristics can certainly help enhance the progress of work and benefits his or her colleagues as well.
