These days, Americans worry most about an economic recovery that President Obama calls "painfully slow". But on Saturday millions will remember the day al-Qaida terrorists flew airplanes into the World Trade Center in New York and the Pentagon in Washington. Another hijacked plane crashed in a field in Pennsylvania when passengers rebelled. Close to three thousand people died that day. Next year will be a big anniversary, ten years since the day Americans call 9-11.

       But this September eleventh comes at an uneasy time. A large number of Americans say they oppose plans to build an Islamic center near the World Trade Center site in New York. This week attention centered on a Christian minister(基督教事工) with a small following in the state of Florida.

       Reverend Terry Jones said he would mark the 9-11 anniversary by burning copies of the Quran(可蘭經(jīng)). He said he wanted to send a message to Islamic extremists. He said, "We are not hateful toward Muslims. We are not aiming this at Muslims, we are aiming this at Sharia law(伊斯蘭教教法)."

       Political and religious leaders around the world had condemned him. The plan even led the State Department to warn American travelers to avoid places where protests(抗議) might take place.

       President Obama said burning Qurans could endanger American troops and invite more extremism. Defense Secretary Robert Gates called Mr. Jones on Thursday to urge him to reconsider.

Administration officials called the idea of burning Qurans "un-American." But they also agreed that it would be within constitutional rights, like protesters who burn American flags. The Constitution guarantees free speech and bars the government from restricting the practice of religion.

According to this news article how many things made this September 11 uneasy? (No more than 1 word)

What did the State Department think would happen after Reverend revealed his plan? (No more than 4 words)

How did the government prevent the situation becoming worse? (No more than 9 words)

Why couldn’t the US government forbid Reverend to burn Qurans? (No more than 7 words)

Some of the best-known names in the entertainment industry have taken part in an unprecedented telethon to help victims of the terrorist attacks in the United States.

The benefit(義演), called “America: a Tribute to Heroes,” was sponsored by all four major U.S television networks, ABC, CBS, FOIX and NBC. It was broadcast by three-dozen television, cable and radio networks across the country and aired live to more than a hundred countries around the world.

Hollywood stars joined music entertainers in asking listeners and viewers to pledge cash donations to charities helping the victims of the September 11th attacks.

Actors, including Tom Hanks, Julia Roberts, Tom Cruise and Clint Eastwood, told stories of heroic acts by people who tried to save others from the burning World trade Center and the Pentagon. Former heavyweight champion Muhammad Ali made a rare public appearance in show of support.
