WORTH NOTING ON TV
House of Representatives (C-Span, 10 a.m., to conclusion, EST): The channel's regular coverage.

the four teams that will play in the NCAA semifinals (check local listings for the games broadcast in your area). * FRIDAY
NCAA basketball championships (CBS, 8 p.m. to midnight, EST): More regional semifinal games.
World Figure Skating Championships (NBC, 8-9 p.m.): Since neither Nancy Kerrigan nor Tonya Harding will be competing, eyes will be focused right where they should be - on the competition itself. Figure skaters from 41 countries will vie in this delayed-tape broadcast from Japan's Makuhari Event Hall.
...talking with David Frost (PBS, 9-10 p.m.): Frost's guest is Vladimir Zhirinovksy. It's a fascinating equation, when you think about it: the urbane, skilled interviewer and the surly Russian ultranationalist who became an important - perhaps ominous - challenger to Russian President Boris Yeltsin after parliamentary elections four months ago. If anyone can handle him, it's Frost. The interview was taped in Zhirinovsky's Moscow offices. * SATURDAY
The Prince and the Pauper (ABC, 8-9 p.m.): Mickey Mouse may be the world's most familiar pop symbol, but he doesn't often make it to prime time. The animated special premiering here is his first new cartoon in seven years. It finds him in a dual role - a bored, pampered prince and a pauper who is his dead ringer. When they trade places, Goofy, Pluto, Donald Duck, and other Disney regulars get into the act, as comedy and confusion reign. (``Mickey and the Beanstalk,'' a Disney short, rounds out the hour.)
World Figure Skating Championships (NBC, 8-11 p.m.): More coverage. * SUNDAY
World Figure Skating Championships (NBC, 7-8 p.m.): Final coverage.
