CNN News:曼德拉留给世人的丰厚遗产

CARL AZUZ, CNN ANCHOR: Welcome to CNN STUDENT NEWS. As the new week begins, many people around the world are paying tribute to Nelson Mandela. He helped end apartheid, South Africa`s practice of racial segregation. He became the country`s first democratically elected president. Mandela died last Thursday at 95. Our show from last Friday covered his life and legacy.

Yesterday was the National Day of Prayer in South Africa. An official memorial service is scheduled for tomorrow. Several world leaders are set to attend. Mandela`s memory is being honored around the globe.

AZUZ: For our first "Roll Call" of the week we thought we`d add a little color to "Roll Call" festivities. We are going to start with the purple Riders from Martins Ferry`s High School in Martins Ferry, Ohio. Over in Fishers, Indiana, we`ve got the Golden Hawks from Riverside Junior High, and we`ll round out our roll with the Red Devils, they are from Central High School in Phoenix City, Alabama.

Economic indicators and winter weather. Economy`s up first. The new U.S. unemployment rate seven percent. Lowest it`s been in five years. In November, the economy added 203,000 jobs. Some experts see this as good signs for the economy. But there are still 11 million unemployed Americans and more than a third of them have been out of work for at least six months.

Like economic data, weather reports are full of highs and lows. In Dallas, last Wednesday, for example, the high was 80 degrees. By Thursday night, a low in the 20s. A winter storm blasted into the region bringing freezing rain and sleet. The winter weather moved east over the weekend. Experts predicted temperatures would be back on the rise today.

When someone from one country visits another, it`s unusual for that person to be held prisoner. That`s what happened to Merrill Newman, though, when he took a trip to North Korea. The country isolates itself from most of the rest of the world, so it`s very difficult to understand its decisions. One thing we do know is that the situation involving Merrill Newman is over.
