A new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It has changed the way we work. Already we’re partly there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth (广度) of the economic transformation can’t be measured by numbers alone, because it also is giving rise to a basic new way of thinking about the nature of work itself. Long-held concepts about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip (芯片), would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more important, and the people who possess it, whether they work in manufacturing (制造业) or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant (最重要的). It will be the way you do your job.

A new study says that birds living in big cities sing shorter, faster songs that are higher-pitched (高音调的) than those sung by their brothers in the forests. The researchers think that the birds adjust their songs to allow themselves to be heard over the noises of the city, especially the low traffic noise.
To study how urban birds song, Hans Slabbekoorn and Ardie den Bore, biologists at the University of Leiden in Netherlands, travelled around Europe and recorded bird songs in ten major cities and in nearby forests. The species they focused on, the great tit (大山雀), is widespread across Eurasia and one of the few types of birds that thrives in big cities.
Singing is crucial (重要的) for males, which use their songs to attract mates and mark out their territory. The changing songs could play a role in eventually causing the city birds and the forest dwellers to evolve into separate species.
The findings could also help explain why usually only a few bird species thrive in cities. By contrast, many more bird species tend to be found in forests and other undeveloped habitats.
Studies like this could eventually help researchers predict how urbanization (都市化) will affect birds, using this knowledge could help urban planners design more pleasant city environments, study co-author Slabbe-koorn said. “You can make a city much more livable if you pay attention to where the noise goes and where the people go,” he said. “It would be easy to fit the birds into those models.” Then cities wouldn’t be strictly for the people, but also for the birds.
