    (D) Most new people were born in developing countries. These countries are found in much of Africa, South America and some parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average, only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world’s population lived in the developed countries. By 2050, these countries will be home to only around one tenth of the world’s people. In the developing countries, more than one billion people are still living below the poverty(贫困)line. These people do not have enough food to eat and they live in poor housing. Children get little time at school and people suffer from many kinds of diseases. At the beginning of the 21st century, the world’s population was around six billion people. The U.N. has said that the world’s population will level off at 12.5 billion by the year 2100. Other groups think the world’s population will continue to grow, reaching 14 billion before it becomes stable, or even falls. 根据短文内容.回答下列问题. 46.

    In the US, the most popular way to welcome the new year is with a big party. Some parties are at private homes. But in recent years, it has become more and more common for Americans to go to a hotel or eating-place on the night of December 31st. There, they can eat a big dinner, drink champagne, and dance to orchestra music.
    Most New Year’s parties are usually noisy. People shout and sing. And often, guests blow on small noisemakers when the new year arrives at midnight. This tradition of noise making is believed to start centuries ago. People thought that loud sounds would drive away the bad spirits of the old year.
    The biggest, noisiest New Year’s party in the US takes place in Times Square in New York. Thousands of people gather(聚集) there. Some of them ring bells and set fireworks. Others blow whistles of car horns(喇叭). And at twelve o’clock, they begin to cheer as an electric sign in the shape of a red apple lights up on top of a tall building.
    The Times Square celebration includes another well-known American tradition. Since 1929, the band of musician Guy Lombardo has given a concert on New Year’s Eve. Guy Lombardo died in 1977. But, Bill Lombardo, has kept the tradition alive with a band concert at a New York city hotel. When the crowds in Times Square start cheering the arrival of the new year, television cameras show the band playing the song Auld Lang Syne.

    Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.

    It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.

    Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.

    Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.

    Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.
