电台主持人 radio host;
电视主持人 TV host

　　The work of radio hosts and TV hosts is similar to each other in many ways. First, both radio hosts and TV hosts must be fluent in languages. Second, they are all supposed to have a wide knowledge of culture, history, geography and so on. In addition, they must give completely correct information.
　　However, there are also some differences between them. For the TV hosts, they must pay much attention to their appearances while the radio hosts needn’t. Besides, TV hosts can make use of pictures to express themselves more clearly but the radio hosts can not.
In my view, TV hosts are under higher pressure, but they can show their talents better.
