INTERNATIONAL Israel could not join a cease-fire in Lebanon as long as Palestinian groups continue their attacks on Israel. Prime Minister Menachem Begin reportedly told Philip C. Habib, the American special envoy in the Middle East. Israeli officials said Mr. Begin told Mr. Habib during the course of two meetings that a halt in the fighting was not a solution to the more basic problem of a Palestinian Liberation Organization arms buildup within striking distance of Israel's northern settlements. He reportedly stressed that Israel could agree to a cease-fire only the context of a border peace arrangement. (Page A1, Column 6) Shipment of more U.S. jets to Israel would be affected by Israel's cooperation in reducing the level of violence in Lebanon, Secretary of State Alexander M. Haig said in a television interview. (A3:3-6.)

The announcement of a comprehensive immigration policy, delayed by disagreements among President Reagan's advisers, is expected this week. But the plan may not include a suggested national identity card. The announcement is likely, according to Administration officials, to contain other elements recommended by an 11-member advisory committee headed by Attorney General William French Smith. But the officials said that some disputed elements of the report have been diluted.

Assembly Speaker Stanley Fink ruled out yesterday any state commitment to pick up all extra costs for the proposed Westway highway project that might be left by shortfalls in Federal aid. Mayor Koch has said the state must make such a commitment before he would agree to the project. Mr. Koch has been negotiating with Governor Carey, but Mr. Fink, a Brooklyn Democrat, and a spokesman for the state's top Republican leader, Senator Warren M. Anderson, made it clear that the Legislature would not back the Governor in such a promise. The Federal Government has said it could provide $1.6 billion for the Westway, but a key issue in the debate over the highway project has been who would cover Federal aid cuts or cost overruns. Mayor Koch, responding through a spokesman to Mr. Fink's remarks, said: ''I am weighing all of the factors that will go into my final decision. And, of course, that statement will have to be included.''

It is Long Island's most exclusive and perhaps least-known summer colony. It has no name and if you don't already belong, you can't join: The membership books were closed in 1964. But don't look for brooding mansions and gatehouses, vintage automobiles and golf greens. This colony on the water -and occasionally in the water - consists of cottages that once were shacks, built in some cases before World War I and occupying a maze of muddy marsh flats in the Hempstead Bay wetlands.

DANVERS, Mass. THE most acclaimed hockey player the United States has produced wears a Gregory's Deli jersey as he skates against Moynihan Lumber. Outside the Town Line Twin Rinks on Route 114, it is a steamy July evening. But inside it is cold, and the men from the town wear the warmup jackets of their youth as they join Sgt. Bob Carpenter of the Peabody police force watching his son, Bob Jr. It is a scene that has gone on here for more than 10 years. It will not go on much longer. Young Carpenter, who turned 18 years old last week, has graduated from high school and has signed a letter of intent to attend Providence College, which is perhaps one top player from capturing the national collegiate hockey championship. But Carpenter also was the third pick last month of the entire National Hockey League draft, plucked under surprising circumstances by the Washington Capitals; no other American player was ever chosen higher on the first round - and no other high school skater from the United States was ever picked in that round.
