LONDON(Reuters)—Ecotourism(生态旅游) is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers.
Biologists and conservationists(自然环境保护论者) are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.
“Evidence is growing that many animals do not react well to tourists in their backyard,” New Scientist magazine said.
The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone(荷尔蒙) levels but they fear it could get much worse and over the long term “could endanger the survival of the very wildlife they want to see”.
Although money produced through ecotourism, which has been growing at about 10～30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union and some governments fear not all projects are audited (审计) and based on environmentally friendly policies, according to the magazine.
“The transmission(传播) of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding,” said Philip Seddon of the University of Otago in Dunedin, New Zealand.
Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by ecotourists are producing smaller babies.
Conservationists are not calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.
“The animals’ welfare should be very important because without them there will be no ecotourism,” said Rochelle Constantine of the University of Auckland in New Zealand.

Americans have contributed to many art forms,but jazz,a type of music,is one of the art forms that was started in the United States.Black Americans,who sang and played the music of their homeland,created jazz.
Jazz is a mixture of the music of Africa,the work songs the slaves sang,and religious（宗教）music.Improvisation is an important part of jazz.This means that the musicians make the music up as they go along,or create the music on the spot.This is why a jazz song might sound a little different each time it is played.
Jazz bands formed in the late 1800s.They played in bars and clubs in many towns and cities of the South,especially New Orleans.New Orleans is an international seaport,and people from all over the world come to New Orleans to hear jazz.
Jazz became more and more popular.By the 1920s,jazz was popular all over the United States.By the 1940s,you could hear jazz not only in clubs and bars,but in concert halls as well.Today,people from all over the world play jazz.Jazz musicians from the United States,Asia,Africa,South America,and Europe meet and share their music at festivals on every continent.In this way jazz continues to grow and change.What can be the best title of the passage?

Snow-melting Agent
A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites.
On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets.
One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees’ roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees.
Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers.
In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads.
Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents.
Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today’s criteria must still be used carefully,we have to rely more on our manpower and machines to clear off snow.
This year,in addition to using snow-melting agents,Beijing will use a large number of snow vehicles to clear snow on roads.In more places,citizens are mobilized to clear snow with their hands.This may be a test of a city’s civilization level.Salt is a snow-melting agent while _________ is a cleaning agent.
| A．water | B．soap | C．a washing-machine | D．a housewife |
The third paragraph of the text is mainly about _______.
| A．the side effect of snow-melting agent |
| B．a case of damage to trees caused by snow-melting agent |
| C．the results of using snow-melting agent |
| D．the uses of snow-melting agent |
According to the text,the most practical way to clear off snow is to _________.
| A．use snow-melting agent as much as possible |
| B．only use more harmless snow-melting agent |
| C．encourage people to clear snow with their hands |
| D．use more snow vehicles |
This text most probably appears in_________.
| A．a newspaper | B．a magazine on latest findings |
| C．a book on salt | D．a magazine on environmental protection |
Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.
Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?
Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation of the application of nano technology into medicine.
Ji(director Institute of Nanomedicine):
A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.
Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.
The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.
Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.Which of the following shows the right relationship?
| A．nanometer<millimeter<micrometer<meter |
| B．nanometer<micrometer<millimeter<meter |
| C．micrometer<millimeter<nanometer<meter |
| D．millimeter<micrometer<nanometer<meter |
The underlined part in the last second paragraph but one is about_________.
| A．the strong points of nano cups | B．the shortcomings of nano cups |
| C．the uses of nano cups | D．the wonders of nano cups |
Which of the following does not show that nano cups are different from ordinary cups?
| A．Nano cups can’t make people healthier. |
| B．Nano cups are made of a different material. |
| C．Nano cups are much easier to be cleaned. |
| D．Nano cups are hard to produce. |
According to the text,nano cups in the market are_________.
| A．only traditional products |
| B．ordinary cups covered with a little nanometer material on the surface |
| C．cups made of a nano material |
| D．cups made of a mixed material |
Interpersonal Distance
With the outbreak of SARS,everyone tried to avoid coming into close contact with each other.In those days,interpersonal distance increased,“close contact” almost became synonymous with “danger”,and even children couldn’t have close contact with their mothers.Now SARS has disappeared,and we return back to normal living again.Then,how can we do handle interpersonal distance in our everyday lives?
Studies show that interpersonal distance can be divided into 4 different types:intimate distance,personal distance,social distance,and public distance.
Intimate distance is the interpersonal distance of a person with the people closest to him or her.It ranges from 0 to 45 cm.When a stranger comes within this distance,a person will have strong negative reaction.In crowded buses,strangers usually maintain rigid poses and try to avoid body contact,but couples,lovers,children and their mothers usually lean close to each other.Intimates who aren’t able to live close together for a long time can become alienated.Also,touching is also very important.A contrast test shows that the nervous systems of babies who are often caressed by their mothers develop much faster and their weight increases faster,by 47%,than that of other babies.
Personal distance ranges from 45 cm to 1 m.People can converse genially at this distance without invading each other’s personal space.When friends and acquaintances meet on the street,they usually greet and converse at this distance.
Social distance generally ranges from 1 m to 3 m.Among this range,1-2 m is usually the distance in which people deal with private affairs in social activities.For example,when you get money from banks,in order to protect your privacy,other customers are required to stand at least 1 m away from you.2-3.5 m is a farther social distance.Business talks usually occur at this distance.Besides talking,proper eye contact is also indispensable.Otherwise,each side will feel disrespected.
Public distance is usually used in public gatherings.It generally ranges from 3.5 m to about 7 m.Beyond this range,people can’t communicate using a normal voice.In classrooms,experienced teachers usually leave their lecture platforms to enhance their teaching.
Under different cultural contexts,the interpersonal distance differs slightly,but its basic laws are the same.When conversing,people in love lean very close to each other,acquaintances lean closer than strangers,females lean closer than males,and extraverts lean closer than introverts.In life,harmonious interpersonal relationships are set upon proper interpersonal distances,and some conflicts start from improper interpersonal distances.According to the text,the strangers standing close to each other in a crowded bus may_________.
| A．try to keep a distance away | B．feel uneasy |
| C．feel nervous | D．be rude to each other |
The distance between a teacher and students in class belongs to _________.
A.intimate distance C.personal distance
C.social distance D.public distanceThe interpersonal distance between two people is mainly determined by _________.
| A．how familiar they are with each other | B．their relationship in a special activity |
| C．their characters | D．their cultural background |
To keep proper interpersonal distance is important because _________.
| A．it makes people feel respected or loved |
| B．it helps to protect privacy |
| C．wrong interpersonal distance may result in misunderstanding |
| D．improper interpersonal distance may hurt others |
