New Olympic event – BMX

Tonight’s must-see

Olympics, 8 p.m. to midnight, NBC. In the last day for gymnastics, there are individual medals for women’s balance beam and men’s parallel and high bars.

Meanwhile, track-and-field events continue. Men have the 1,500-meter run; women have the 400-meter run and the 100-meter hurdles.

There’s more, including (after 10 p.m.) a new Olympic event, BMX cycling.

Tonight’s might-see

“Jaws” (1975), 8-11 p.m., MyNetwork. On a quiet week (outside the Olympics) we get four days of great-white scares.

Tonight is Steven Spielberg’s film, with talented humans (Richard Dreyfuss, Robert Shaw, Roy Scheider) and a fierce, fake shark. The sequels (not directed by Spielberg) air Wednesday through Friday.

Other choices include

More Olympics. NBC is also 10 a.m.-1 p.m. and 12:35-5 a.m. On cable, USA is 11 p.m.-9 a.m., MSNBC is 2 a.m.-2 p.m., CNBC is 9-11 p.m.

“NCIS,” 8 p.m., CBS. A dog has been accused of killing its master; Abby has doubts.

“House,” 8 p.m., Fox. Last week, Dr. House was trying to work a case on his own. Told that he must have aides, he suddenly has 40 of them, diagnosing a secretive astronaut.

“Terminator: The Sarah Connor Chronicles,” 9 p.m., Fox. Breaking into the FBI agent’s apartment, Sarah is startled to find a file dealing with her psychiatrist.

PBS’ “Wide Angle: Iraqi Refugees” (9 p.m.) KSPS and KUID, and “P.O.V.: The Judge and the General” (10 p.m.), KUID. Two strong shows wrap up their seasons. “Angle” views the flood of refugees from Iraq. “P.O.V.” has the compelling story of a mild-mannered Chilean judge, a quiet conservative who was expected to ignore a probe of former dictator Augusto Pinochet. Instead, he researched murder and tortures, then issued three indictments.

“Primetime: Medical Mysteries,” 10 p.m., ABC. One story views a 12-year-old who is 7 feet tall. Another involves silver poisoning, which causes the skin to turn blue.
