WORTH NOTING ON TV

FRIDAY French Open (NBC, 10 a.m.-1 p.m.): It's the men's semifinals in one of the tennis world's Grand Slam tournaments, with same-day coverage from Roland Garros Stadium in Paris. Great Performances (PBS, 9-11 p.m.): The TV debut of American composer Dominick Argento's opera ``The Aspern Papers,'' based on the Henry James novella, was taped at its world premi`ere last fall in a Dallas Opera production featuring Frederica von Stade, Elisabeth Soederstrome, and Richard Stilwell. SATURDAY LUCAS (CBS, 8-10 p.m.): He's a shy but spunky loner who loves symphonies and science, and some of his high school peers think he's a nerd. But this TV movie's 14-year-old title character, played by Corey Haim, also has the courage to stick his neck out for a girl he likes. French Open (NBC, 3-6 p.m.): Tennis: women's singles final. Wild America (PBS, 6-6:30 p.m.): Predators and their prey sometimes evolve together in a natural balance, as this often fascinating series illustrates in an edition called ``The Grouse and the Goshawk.''

SUNDAY French Open (NBC, 9 a.m.-2 p.m., ET): Tennis: men's singles final, covered live. Masterpiece Theatre (PBS, 9-10 p.m.): The Bretts are back. For Series 2, ``Home and Away,'' the British theatrical family is now making its rather strange way into the 1930s - with a few harrowing moments in this opening episode.

MONDAY Return of the Wolves (PBS, 9-10 p.m.): Actually turning wolves loose in the hope they'll proliferate! It would probably seem a horror story to the generations of people who have feared them over the centuries. But in Yellowstone National Park they've been doing just that, and for good reason: to prevent extinction, one of many steps documented in a program - shot on location in Alaska, and Glacier and Yellowstone - about the plight of these grossly misunderstood animals.

TUESDAY The UN: What's in it for the US? (PBS, 10-11 p.m.): To answer this often-asked question, a panel of former US ambassadors to the UN discusses the Annual Report of the United Nations and the changing roles played by China and the Soviet Union.
