CNN News:美国政府关闭风险进入倒计时

Big thanks to Big Blue and to those students atHamilton High for getting a starter today.

Yesterday, we explained a little bit about the UnitedNations General Assembly, it's annual meeting that'shappening this week in New York City.

Leaders and representatives from around the world have come to the United Nationsheadquarters.

They all get to make speeches to the General Assembly about issues they think deserve theU.N.'s attention.

President Obama spoke yesterday morning.

This is part of a president's role asAmerica's chief diplomat, speaking on behalf of the country about international issues.

President Obama talked about the civil war in Syria, the recent economic struggles in the U.S.and overseas.

He also focused on Iran.

In yesterday's show we discussed the decades of tension between the U.S. and Iran.

In his speech, President Obama talked about the possibility of the countries finding commonground.

The roadblocks may prove to be too great.

But I firmly believe the diplomatic path must be tested.

From all the status quo we'll only deepen Iran' isolation.

Iran's genuine commitment to go down a different path will be good for the region and theworld.

And we'll help the Iranian people meet their extraordinary potential in commerce, in culture,in science and education.

Here are five things to know about a possible U.S. government shutdown.

Number one, it's up to Congress and the president to work this out.

Congress has the job of passing spending bills that fund the U.S. government.

And the president signs those bills in the law.

The government's financial year starts now next week, that's why the deadline is October 1st.

Two, President Obama's health care reform law: the Affordable Care Act or Obamacare factorsin.

Recent polls indicate public support for Obamacare is weakening.

The Republican-led House of Representatives has voted to fund the government, but only if thehealth law is defunded, effectively killed.

Neither the Democratic-led Senate nor the president will go for that.

So, someone will have to compromise on Obamacare to avoid a shutdown.

Three, this wouldn't be the first time the government has shut down.

The last two times were in the 1990s, one of them lasting 21 days.

It was the longest shutdown in American history.

Four, many Americans, though, maybe not everyone would notice.

Some government workers would be furloughed, forced to take time off without pay.

Vacation plans for millions would change because national parks and museums like theSmithsonian would be closed, and Americans wouldn't be able to get passports or certaingovernment loans until the shutdown ended.

The government workers considered essential, the military, the FBI, air traffic control, theTSA, they'll all stay on duty.

Government medical coverage, Medicare or Medicaid would still be there for those who need it.

And you'll still get snail mail. Postal delivery wouldn't change.

Five, the economic impact.

It really depends on how long a shutdown would last: a few days likely wouldn't have muchimpact.

But a few weeks could make a dent in gross domestic product, and in a fragile economy, thatcould hurt.

An update for you now from Kenya.

We've been reporting on a terrorist attack at the shopping mall in the nation's capital city ofNairobi.

Yesterday, Kenya's president said security forces had ashamed and defeated the gunmen.

This all started on Saturday with the attack on the Westgate shopping mall.

Al Shabab said it was responsible.

This is a terrorist group based in Somalia, one of Kenya's neighboring countries.

The attack turned into a standoff.

Then yesterday, security forces said they were making final sweeps through the mall.

Kenya's president said three floors inside had collapsed, although he didn't explain what causedthat.

He described the country as bloodied, but unbowed.

See if you can I.D. me.

I have more than 1,000 members, mostly colleges and universities.

My president is Mark Emmert, and my headquarters is in Indianapolis.

I'm the NCAA, and I'm responsible for creating and enforcing rules for college athletics.
