【正确答案】Advantages:
E-mail is fairly fast. Using e-mail, the delivery of a message can take a few seconds to a day or so, this depends on the network transmission and the delay in the recipient's reading.
E-mail is asynchronous communication, which means communication that does not occur at the same time. Thus one sends a message, which can be read by the recipient at any time, which is convenient for him or her. This is a very useful factor for communicating between long distances and different world time zones.
Another important advantage in use of e-mail is its rather cheap service. Thus e-mail allows one to have a large number of correspondents worldwide (one can sent an e-mail to New Zealand being himself/herself situated somewhere in Europe for example), with cost of a single local call.
When one uses online e-mail services, then it is absolutely free of charge.
Disadvantages:
E-mail has quite low level of security and privacy. The majority of the e-mails are delivered to the correct addressee. However, sometimes, messages may be delivered to individuals other than the sender or recipient. This could occur because of a simple mistake: the address of the recipient was typed incorrectly (one wrong letter makes an error), or there has been a transmission error etc..
Another thing that can be considered as a disadvantage is that in many cases the storage limit of the e-mail inbox is not that big. This mainly goes for online free services.
Also it is important to mention the case of e-mail forgery. This can occur when for instance: one can send an e-mail as someone else, and it is not a very hard trick to do (this among other ways can be done by simply changing the e-mail address of the sender). That means that when receiver gets the e-mail he/she thinks it was sent from a certain person/address, when in reality it is being send by a different person, perhaps a complete stranger.

【正确答案】Advantages:
The people have a right to know about those in power over them. Their salaries are paid for by the people (whether through taxes, in the case of politicians and civil servants, or by revenue generated by films, CDs, TV, etc., in the case of celebrities). The decisions of public political figures affect many aspects of people's lives; in exchange the people have the right to make informed judgments about the kind of leaders they have. Any attempt to restrict what may be reported about public figures in the press could easily become a conspiracy to keep voters in the dark and to manipulate them.
No clear dividing line can be drawn between public and private behavior drawing up rules will be arbitrary and will exclude at least some corrupt or dishonest behavior of bearing.
Public figures seek this status knowing that it will bring attention to their private lives-pop stars, footballers, etc. Constant scrutiny is the price of fame. Many celebrities actively seek media exposure in order to advance their careers, revealing many aspects of their personal lives; once success has been bought in such a fashion it is hypocritical to complain of "press intrusion" into those few aspects the star would prefer to remain hidden.
Disadvantages:
The public interest' is not the same thing as what the public is interested in. There will always be a fascination in learning intimate details about the lives of the powerful and famous, but this should not be a reason to deny public figures the right to privacy that the rest of us enjoy. Nor should public figures be held to higher standards of personal behavior than the rest of society by a sensationalist press seeking only to sell newspapers. If newspapers were forced to focus upon the policies and public actions of politicians, rather than their personal foibles, democracy would be better served.
Many public figures achieve celebrity status largely by mistake; it is a by-product of their pursuit of success in their particular field. For example, most professional footballers wanted when young simply to become the best player they could be, at the highest level they could reach. They do not wish to be "role models" and claim no special moral status, so why should their private lives be subjected to such public scrutiny?
