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.

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people and a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attracts the tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must have other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Business can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first-class roads, and other support facilities (配套设施) needed by tourist attractions. For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, job and money are lost.

Recently a Beijing father sent in a question at an Interact forum(论坛)asking what“PK”meant.
“My family has been watching the‘Super Girl’singing competition TV programme.My little daughter asked me what’PK’meant,but I had no idea,”explained the puzzled father.
To a lot of Chinese young people who have been playing games online,it is impossible not to know this term.In such Internet games,“PK”is short for“Player Kill”,in which two players fight until one ends the life of the other.
In the case of the“Super Girl”singing competition.“PK”was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father,Chinese teachers at high schools have also been finding their students’compositions using Internet jargons which are difficult to understand.A high school teacher from Tianjin asked her students to write compositions with simple language,but they came up with a lot of Internet jargons that she didn’t understand.
“My‘GG’came back this summer from college.He told me I’ve grown up to be a‘PLMM’.I loved to‘FB’with him together;he always took me to the‘KPM’,”went one composition.
“GG”means Ge Ge(Chinese pinyin for brother).“PLMM”refers to Piao Liang Mei Mei(beautiful girl).“FB”means Fu Bai(corruption).“KPM”is short for KF.Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
