Idema, a Dutch Sinologist（汉学家）, has served as the director of the Chinese Languages and Cultures Department at Leiden University of the Netherlands and was also director of Harvard's Fairbank Center for East Asian Research.He has studied ancient Chinese plays, novels and literature, and has authored or translated a number of influential books published in English and other languages.

    The 70-year-old Dutch Sinologist recalled his half-century-long romance with Chinese culture during a recent visit to Beijing.As a child,the vivid descriptions of China in Nobel and Pulitzer Prize-winner Pearl S.Buck's books sparked Idema's interest in the country.He later read classic Chinese literature and spent whole days pouring through works at the National Library of China.

    While many other experts on China focused on the country's economic transformation, Idema continued to study traditional Chinese literature."There were scholars studying law, religion and society, but not traditional Chinese literature,which was my personal interest," Idema explains.

    Finding reference books for his research,especially regional publications,used to be a huge challenge,and Idema used to spend a lot of time collecting books and other materials during visits to China.Now it is much more convenient with the Internet.

    Idema usually chooses less-known subjects for his research and tries to get firsthand materials.In recent years, he has devoted himself to translating Chinese folk tales and writing about Chinese folk society and folk culture.

    "Traditional Chinese culture is a passion.I have been studying it for 50 years and will continue to do so,"says the retired professor.

    Grown­ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials(尝试)increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables(乘法口诀表)are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming(突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

    When it comes to car hiring,all car hire companies require that you should have a full driving license for at least one year,some of whom may ask for two years,especially for younger drivers.

    Most car hire companies will not automatically hire out a car to someone under the age of 25 or to people over 70. But there are exceptions. Some listed companies are normally prepared to serve people of 21 and over. And some may go over the age limit and provide service for older people( aged 70 and over) providing you have no record of breaking the law and valid license, and a doctor's letter of good health.

    Now read on for some information about national companies with many bases hiring out cars to people aged 21 and older drivers.

From birth to death, the word kick has been given an important part in expressing human experience. The proud and happy mother feels the first signs of life kicking inside her body. And that same life——many years later—— comes to its end in a widely-used expression, to kick the bucket( 吊桶) . The expression to kick the bucket is almost 200 years old. One belief is that it started when an English stableman(马夫) killed himself by hanging while standing on a bucket. He put a rope around his neck and tied it to a beam(梁柱) in the ceiling, and then kicked the bucket away from under him.

    Another old expression that comes from England is to kick over the traces. Traces were the chains（链子） that held at horse or mule to a wagon(货运马车)or plow. Sometimes, an animal refused to obey and kicked over the traces.

    Kick around is an expression that is heard often in American English. A person who is kicked around is someone who is treated badly. Usually he is not really being kicked by somebody's foot. He is just not being treated with the respect that all of us want. A person who has kicked around for most of his life is someone who has spent his life moving from place to place. In this case, kicking around means moving often from one place to another. Kick around has another meaning when you use it with the word idea. When you kick around an idea, you are giving that idea some thought.

    There is no physical action when you kick a person upstairs, although the pain can be as strong .You kick a person upstairs by removing him from an important job and giving him a job that sounds more important, but really is not.

    Still another meaning of the word kick is to free oneself of a bad habit, such as smoking cigarettes. Health campaigns urge smokers to kick the habit.  

    There has, in recent years, been an outpouring of information about the impact of buildings on the natural environment. Information which explains and promotes green and sustainable construction design, strives to convince others of its efficacy (功效) and warns of the dangers of ignoring the issue. Seldom do these documents offer any advice to practitioners, such as those designing mechanical and electrical systems for a building, on how to use this knowledge on a practical level.

    Although there are a good many advocates of "green" construction in the architectural industry, able to list enough reasons why buildings should be designed in a sustainable way, not to mention plenty of architectural firms with experience in green design, this is not enough to make green construction come into being. The driving force behind whether a building is constructed with minimal environmental impact lies with the owner of the building; that is, the person financing the project. If the owner considers green design unimportant, or of secondary importance, then more than likely, it will not be factored into the design.

    The commissioning (委任) process plays a key role in ensuring the owner gets the building he wants, in terms of design, costs and risk. At the predesign stage, the owner's objectives and expectations are discussed and documented. This gives a design team a solid foundation on which they can build their ideas. Owners who skip the commissioning process, or fail to take "green" issues into account when doing so, often come a cropper once their building is up and running. Materials and equipment are installed as planned, and, at first glance, appear to fulfil their purpose adequately. However, in time, the owner realizes that operational and maintenance costs are higher than necessary, and that the occupants are dissatisfied with the results. These factors in turn lead to higher ownership costs as well as increased environmental impact.

    In some cases, an owner may be aware of the latest trends in sustainable building design. However, firms should not take it as read that the client already has an idea of how green he intends the structure to be. Indeed, this initial interaction between owner and firm is the ideal time for a designer to outline and promote the ways that green design can meet the client's objectives, thus turning a project originally not destined for green design into a potential candidate.

    Typically, when considering whether or not to adopt a green approach, an owner will ask about additional costs or return for investment. In a typical project, landscape architects, mechanical and electrical engineers do not become involved until a much later stage. However, in green design, they must be involved from the outset, since green design demands interaction between these disciplines. This increased cooperation clearly requires additional cost. However, there may be financial advantage for the client in choosing a greener design. There are examples of green designs which have demonstrated lower costs for long-term operation, ownership and even construction.
