阅读下列短文，从每题所给的四个选项A、B、C和D中，选出最佳选项。

The media provides us with the observations and experiences from which we build up our personal understanding of the world and how it works.Much of our view of reality is based on media messages.The media，to a great extent，gives us our sense of reality.

Freedom of the media carries with it certain responsibilities of honesty，fairness，accuracy and account-ability.The power of the media to create and destroy human values comes with great responsibility.

The media is powerful in the political system，having great influence on politics and on forming social change.The power is to decide who will communicate what to whom.Television can greatly influence the election of a national leader on the basis of his or her image.

Professional journalists do have a code of ethics(道德标准)．Journalists make a judgment about what's safe and appropriate to report，which often involves difficult choices.German sociologist Max Weber distinguishes between“ethics of conviction”and“ethics of responsibility”．According to the latter(ethics of responsibility)，journalists must take into account the foreseeable consequences of their reporting，and the impact it will have on society.The former，on the other hand，asks journalists to tell the truth，regardless of the consequences.According to Weber，both ideas of ethics should be considered.

Without doubt，information is power，and the big owners of the mass media are very powerful people.Television and radio stations，newspapers，magazines，and websites are，largely，owned and controlled by profit-making businesses.It is not strange that their ideas will get promoted at times.

It is my view that such power and responsibility should never be left in the hands of a few.I believe it is our responsibility as concerned citizens to make sure we are not merely passive viewers，readers or listeners.Together we can have a huge influence on the media by making our views known.
