A United Nations report says the number of people in the world is expected to reach 6500 million this July. By the middle of the century, the population could reach more than 9000 million. That would be an increase of 40﹪.
These numbers are fresh estimates for a report on world population change from 1950 to 2050. Hania Zlotnik is director of the U.N. Population Division. She says the world has added nearly 500 million people in the last six years.
But, in her words, "the good news is that new estimates show that it will take a little longer" to add the next 500 million. Mizz Zlotnik says this will probably happen by 2013.
The U.N. report says most population growth by 2050 will take place in less developed countries. Their population is expected to increase from 5000 million today to almost 8000 million. The population of more developed nations is expected to stay about the same, at just over 1000 million.
The report says nine countries will be responsible for about half the world population increase by 2050. These include Bangladesh, China, the Democratic Republic of Congo, Ethiopia and India. The others are Nigeria, Pakistan, Uganda and the United States.
Twelve countries are expected to have populations at least three times the size now. These include Afghanistan, Burkina Faso, Burundi, Chad, Congo and the Democratic Republic of Congo, and East Timor. The others are Guinea-Bissau, Liberia, Mali, Niger and Uganda.
The report says birth rates remain low in forty-four developed countries.
Today, worldwide, there is an average of two-point-six children per woman. This number is expected to fall to just over two children per woman in  2050. But U.N. population experts note that they cannot be sure which way birth rates will go in the future.
The U.N. report also notes that AIDS has increased death rates and slowed population growth in sixty countries. The area most affected by the disease is Southern Africa.
There, how long people live has fallen from an average of sixty-two years in 1995 to forty-eight now. Researchers believe life expectancy will fall to forty-three years by 2015, then begin a slow recovery.
67. Which of the following statements is true?
A. The population growth will slow down in the next few years.
B. Most population growth will take place in developed countries.
C. There is an average of 2.6 children per woman in developed countries.
D. The area most affected by AIDS is Uganda.
68. Which one is the best title of this passage?
A. AIDS slowed population growth.
B. Most population growth will take place in less developed countries.
C. Population growth and death rate.
D. UN world population report.
69．The author believes that the population growth results from_______
A. The birth rate in developed countries is too high.
B. The birth rate in developing countries is too high.
C. AIDS hit only a few countries.
D. A decrease in death rate.
70. Which of the following best describe the author’s attitude towards the rapid population growth?
A. sympathetic     B. happy       C. optimistic     D. critical

People often ask why“Uncle Sam”is a nickname（绰号）for the United Stated of America. The reason is strange but simple.

Once there was a man called Samuel Wilson. He was born in Arlington, Massachusetts, on September 3, 1766. He was called“Uncle Sam”. When Sam Wilson was 14 years old, he joined the army and fought in several battles. At the end of the war, he went to live in Troy in the state of New York. He opened a meat-packing（肉食品包装）business there.

Sam Wilson worked hard and loved his country. Everyone in the city liked him. One day in 1812, a reporter from a newspaper visited his business. The reporter looked at some boxes of meat. He saw the letters“EAUS”on the sides of the boxes.

“What do those letters mean?”he asked one of the workers.

“The EA stands for ‘Edward Anderson’,”the workman replied.“The boxes of meat are for him.”“What about the letters US?”the reporter asked.

These letters really stood for “United States”, but the workman wanted to have a laugh.“Oh,”he said .“They stand for Sam Wilson. He owns this company. We call him ‘Uncle Sam’.”

The worker did not think that the reporter would believe him. But the reporter wrote a story about his visit to Sam Wilson’s business. He wrote that his workers called him“Uncle Sam”and that“Uncle Sam”meant the United States.

Many people liked using the name“Uncle Sam”as a nickname for the United States and soon everyone was using it. In 1961, almost 150 years later, the United States government made the nickname“Uncle Sam”official（官方的）.

　　If you are lost in the mountains, stay calm in the face of darkness, loneliness, and the unknown. It will greatly increase your chances of survival(生存). Many people think that preparing necessary equipment and knowing how to use it are very important, but actually eighty percent of mountain survival is your reaction to fear.

Find a hiding place.

　　Unnecessary labor will make you sweat and make you cold. Find a hiding place around you before trying to start your own construction. If you are in a snow-covered ar-ea, you may be able to dig a cave in deep snow for protection from the wind. You should try to hide yourself in the middle of the mountain if possible. Stay out of the valleys-cold air falls, and the valley floor can be the coldest area on the mountain.

Signal rescuers for help.

　　The best time to signal rescuers is during the day. Signal for help from the highest point possible-it will be easier for rescuers to see you, and any sound you make will travel farther. If you take a box of matches and a space blanket(a special blanket for traveling), build three smoky fires and put your blanket-good side fa-cing out-on the ground.

Do not walk away.

　　It will make finding you more difficult,as search teams will be trying to follow your path and may miss you if you have gone off in a different direction. Searchers often end up finding a car with no one in it.

If you get frostbite(冻伤), do not rewarm the affected area until you're out of danger.

　　You can walk on frostbitten feet, but once you warm the area and can feel the pain,you will not want to walk anywhere. Try to protect the frostbitten area and keep it dry until you are rescued.

(1) When lost in the mountains, you can in-crease your chances of survival if you________.

A．take a space blanket with you
