Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older. Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old. The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in 2008. At that time, the people were between the ages of eighteen and eighty-five. The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. The study also showed that men and women have similar feeling patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow older, they grow more thankful for what they have and have better control of their feelings. They also spend less time thinking about bad experiences. Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry. The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age. According to the survey of The Gallup Organization people are most likely to become happier _ . A) when they are between ages of 18 and 85 B) when they come to their old age C) when they are in their twenties D) when they are eighteen years old

(Question)
On a Saturday morning earlier this September, the world got its first look at the Strati. This electric vehicle is unlike any other currently on the road. It rolls on four wheels, but its body and chassis weren't built in a factory. Instead, Strati's designers used a technology called 3-D printing. It created those parts of the car in one piece, from the ground up. "Compared to a typical vehicle on the road, the Strati definitely looks different," says Greg Schroeder, a senior research engineer at the Center for Automotive Research in Ann Arbor, Mich. He did not work on the new car. His organization studies trends and changes in the auto industry. It took 44 hours to print the new car at the International Manufacturing Technology Show in Chicago. Over the next few days, the car's designers installed additional parts. These included the car's engine, brakes and tires. Then, early on September 13, Jay Rogers climbed into the car, started its engine and drove the vehicle onto the street. Rogers helped found Local Motors. It's the Arizona-based company behind the Strati. Two weeks later, his team printed a second Strati, and just as fast, at a fair in New York City. Justin Fishkin, a local Motors official, sees the Strati as a window into the future. Today, car buyers are limited in their choice of a vehicle. They can order only what car companies have already designed. But in the future, he says, you may be able to design your own car online and then get it printed to order. Manufacturing experts say 3-D printing has begun to revolutionize how they make things. The technology has been around for decades. But these machines used to be so expensive that only large companies could afford them. In the last few years, though, that has changed. Many of the machines are now inexpensive enough for small companies--or even individuals --to own. Some local libraries make them available to the public. High Schools are beginning to use them in classrooms. Wide access to these printers means people can now design and print... Why did Lonnie Love make efforts to improve 3-D printing with his team? A) Because additive manufacturing might produce unreliable materials. B) Because he just was interested in making new things. C) Because he just wanted to build new machines and test them D) Because additive manufacturing is always slow but inexpensive.

Ques: BEIJING, June. 30(Xinhua)----There are ten times as many Chinese newspapers and magazines than there were 30 years ago. That's when the country adopted the reform and opening-up policy. Figures from the General Administration of Press and Publication (GAPP)show there were 186 newspapers and 930 magazines in China in 1978. Today, the country has 2,081 newspapers and 9,363 different magazines. In the meantime, official figures show China has some 600 publishing houses producing nearly 300,000 kinds of books. That's a dramatic increase from the 105 publishers of the past that produced only 10,000 different books. Rapid economic development and universal education since China adopted the reform has helped fuel the need for more information sources. Under the market economy, hundreds of publishing houses and newspapers have taken steps to restructure management systems into corporations listed on the stock market. The legal system overseeing the news and publishing industries in China has also changed over the last three decades. Since 1990 a law and five relevant regulations were adopted in 1990 to govern the sectors. Since it started in 1993, digital publishing has _ . Its industrial volume amounted to 20 billion yuan (2.93 billion U.S. dollars) in 2006. More than 500,000 kinds of digital books were produced last year alone in China, which is more than any other country in the world. You will probably read this text in the _ column of XINHUA NET? A) culture and education B) entertainment C) science and technology D) business

Question: Three years have passed since I entered the university. I haven't seen many of my classmates after we parted when the college entrance examination was over. So we decided to have a get-together party this summer vacation. As you can imagine, I could hardly wait to have the day for our reunion. After several month's waiting, 25 of my former higher school classmates and 3 of our teachers were crowded in a small restaurant near our high school. We were more than happy to meet with each other again. Our former Chinese teacher was so excited that he even choked to say some words. With gratitude, we thanked our teachers for their hard work; with great joy, we exchanged the happy things happening in each of our present colleges; We talked before someone shouted. "Oh, it is 11:30 now." But no one would be the first to say goodbye to others . I shall always bear this unforgettable get-together in my mind. With time passing, I believe I will meet many new friends, but I think the friendship among high school classmates will be the purest and will be the most valuable thing to cherish. What is the writer probably? A) He is a middle school student. B) He is a university student. C) He is a teacher . D) He is a reporter.
