CNN News:索契冬奧會(huì)即將來(lái)臨 安保稱(chēng)史上最嚴(yán)

Welcome to your January Ninth edition of CNN STUDENT NEWS.

I'm Carl Azuz.

In less than a month the XXII Winter Olympic Games will kick off in Sochi, Russia.

The opening ceremony is Friday, February 7th.

Here's by the numbers look at what's ahead: 6,000 athletes competing.

The best in the best in winter sports from 85 countries worldwide.

The Olympics will run 17 days in the resort city.

They'll include 1650 Paralympians and they'll be traveling to Sochi from 45 countries.

Total number of events, 89.

Some of them will take place near Sochi's coast.

Others in the mountains overlooking the city.

This could be the most expensive Winter Games ever.

Russia's spending at least $50 billion on things like roads, railways, stadiums, ski jumps and security.

Russia says this will be the most secure Olympics ever.

25,000 police officers, 8,000 additional security officers.

The country's confident in Olympic safety, and that's despite recent terrorists bombings in another Russian city.

And this could be the warmest games ever.

Sochi's average temperature in February, 47 degrees Fahrenheit.

It's colder than in Vail, Colorado, one of America's largest ski resorts.

It has some of the best skiing in the U.S.

In Vail's back country, away from the mountain itself, the terrain is only for the most experienced skiers and snowboarders.

There is an avalanche control here.

And two skiers and two snowboarders got caught in a sudden slide of snow Tuesday.

Three of them were temporarily trapped.

The fourth person, the grandson of one of Vail's cofounders was killed.

Officials believe the avalanche was caused by the skiers and snowboarders.

Conditions might have been right for one.
