Looking at China's history over the past 60 years，it is apparent that，despite much suffering，the country has achieved huge political，economic and social success，especially during the past three decades.

    The press center for the celebration of the 60th founding anniversary of new China was officially opened on the morning of September 22. Zha Shouchen，deputy director of the press center introduced that，during the National Day，there would be 3,200 domestic reporters，and more than 1,300 foreign journalists to come to Beijing to make the covering work.

    The press center provided many services for domestic and foreign reporters，such as issuing the press cards to reporters，accepting the interview application，organizing press conferences and activities of group interviews，providing the means of communication and information services for reporters.And the following was the scene.

    A grand parade in Beijing on Oct.1，led by the People's Liberation Army and the People's Armed Police Force，showed some of China's latest achievements in defense modernization.About 8,000 military officers，along with tanks and other vehicles，formed a straight line stretching 3 kms.

    The military parade was followed by a civilian parade featuring six massive performing groups and 36 formations of about 100,000 people.In addition,60 floats(彩车)represented everything from the country's geographic areas to the previous year's Beijing Olympics.

    Everyday life in China is a parade on a grand scale，with citizens now being able to enjoy things their ancestors did not dare to contemplate 100 years ago，things their grandparents took for luxury 60 years ago，and things their parents did not even know how to attempt 30 years ago.

    Ladies and Gentlemen, thank you. Well, ni­hao. (Laughter) It is such a pleasure and an honor to be here with all of you at this great university, so thank you so much for having me. I'm here today because I know that our future depends on connections like these among young people like you across the world.

    That's why when my husband and I travel abroad, we don't just visit palaces and parliaments(国会) and meet with heads of countries. We also come to schools like this one to meet with students like you, because we believe that relationships between countries aren't just about relationships between governments or leaders—they're about relationships between people, particularly young people. So we view study abroad programs not just as an educational chance for students, but also as an active part of America's foreign policy.

    Through the wonders of modern technology, our world is more connected than ever before. Ideas can cross oceans with the click of a mouse. Companies can do business and compete with companies across the world. And we can text, email, Skype with people in the world.

    So studying abroad isn't just a fun way to spend a time of learning; it is quickly becoming the key to success in our times. Because getting ahead in today's workplaces isn't just about getting good grades or test scores in school, which are important. It's also about having real experience with the world beyond your borders­experience with languages, cultures and societies very different from your own. Or, as the Chinese saying goes: “It is better to travel ten thousand miles than to read ten thousand books.”

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity (湿度).

    In very cold climates, there is a constant danger of developing hypothermia, which is a life-threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

    In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life-threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

    The United States estimates that about one out of every 10 people on the planet today is at least 60 years old. By 2050, it's projected to be one out of 5. This means that not only will there be more old people, but there will be relatively fewer young people to support them.

    Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics. "Population aging increases the concentration of population in the older ages and therefore it is expensive," he said.

    Aging populations consume (消耗) more and produce less. With more people living longer, it could gel expensive. But Mr. Lee says with continuing increases in worker productivity and wise planning, it can be manageable.

    Societies have different methods for caring for the elderly，but each carries a cost Generally, there are three types of support Seniors can live off the wealth they gained when they were younger. They can rely on their family to take care of them, or they can rely on the movement.

    In industrialized nations, governments created publicly-funded (公共资助的) support systems. These worked relatively well until recent years, when aging population growth in places like the United States and Western Europe began to gradually weaken the systems' finances(资金). These nations now face some tough choices. Mr. Lee says the elderly in some of these countries must either receive less money, retire later or increase taxes to make the system continuable.

    Most developing nations haven't built this type of government-funded support, but have instead relied on families to care for their elderly. These nations also generally have a much younger population, which means their situation is not as urgent as more developed nations. But Mr. Lee says that doesn't mean they can pay no attention to the issue. "Third World countries should give very careful thought to this process, to population aging and how it may affect their economies — now, before population aging even becomes a problem," he explained.

    "Don't tell anyone". We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We often tend to "spill the beans", even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well" become a burden". This is because people often have an "obsessive (强迫性的) and anxious urge to share it with someone".

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other." Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone." according to Shah.

    He added that talkative people could let secrets slip out. But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.
