　　Energy is very important in modern life．People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place．Most energy comes from fossil fuels－petroleum, coal, and natural gas．However, burning fuels causes pollution．Also, if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty－first century．Scientists are working hard to find other kinds of energy for the future．What might these sources of energy be?

Energy from the wind

　　All over the world, people use the power of the wind．It turns windmills and moves sailboats．It is a clean source of energy, and there is lots of it．Unfortunately, if the wind does not blow, there is no wind energy．

Energy from water

　　When water moves from a high place to a lower place, it makes energy．This energy is used to create electricity．In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people．Waterpower gives energy without pollution．However, people have to build dams to use this energy．Dams cost a lot of money, so water energy is expensive．

Energy from the earth

　　There is heat in rocks under the earth．Scientists use this heat to make geothermal energy．San Francisco gets half of the energy it needs from geothermal power．This kind of energy is cheap, but it is possible only in a few places in the world．

Energy from the sun

　　Solar panels on the roofs of houses can turn energy from the sun into electricity．These panels can create enough energy to heat an entire house．Solar power is clean and there is a lot of it in sunny places．But when the weather is bad, there is no sunlight for energy．

　　In China, most people ride bikes to school, or to work, or to places where they want to go．So China is called “kingdom of bicycles”．

　　But Americans are a people on the wheel．Wherever you go, you will see cars．There are so many cars that there is a traffic jam here and there．Now, more and more Americans would not consider it a healthy way of life．In fact, many Americans are strongly against the advancement of the wheel．We should encourage people to use less cars to save our environment and the energy．

　　Everyone wants to reduce pollution．But the pollution problem is very serious．People drive cars and the waste gas from them causes air pollution．On the other hand, the need for energy increases every day, and some sources of energy are running out．Oil will last for no more than 40 years, while coal could last another 300 years．The way we're heading is towards a world where people are going to go cold and hungry．Now in China many rich men live away from downtown．On holidays they go to some big cities and places of interest．Most of them use their own cars．But China is a country with a population of over 1.3 billion．So, if you have enough money in the future, what will you do?

　　When you don't speak, you may be still communicating．It is true that you may not wish to say anything．But your very silence may show your wish to be left alone or to stay uninvolved, which is the message you want to send．

　　So it has been said that while we speak with our vocal organs, we converse with our whole bodies．All of us communicate with one anther nonverbally(非口头地), as well as with words．Sometimes we know what we are doing with the use of gestures such as the thumbs－up sign to indicate that we approve．But most of the time we are not aware that we are doing it．

　　Body language serves a variety of purpose．Firstly it can replace verbal communication, as with the use of gesture．Secondly, it can modify(修饰)verbal communication．Loudness and tone of voice is an example here．Thirdly it regulates social interaction：turn taking is largely governed by non－verbal signals．Fourthly it conveys our emotions．Finally it conveys our attitude towards ourselves and towards the people we are communicating with．This is particularly important for successful cross－cultural communications

　　Every culture has its own body language．So in order to achieve a more successful cross－cultural communications, we heed not only what to say but also how to say it appropriately．Observation shows that a truly bilingual person switches his body language at the same time he switches language．

　　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 program．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 KFC．Pizza Hut and McDonald's．

　　Some specialists welcome Internet jargons as a new development in language．

　　If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female)ora Qing wa(frog, referring to an ugly looking male)is, you will possibly be regarded as a CaiNiao!

　　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．
