LONDON ( Reuters)-- Ecotourism (生态旅游) is causing a lot of damage to wildlife and may be endangering the survival(生存) 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 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 (IUCN) 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 now 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.What's the text mainly about?

We've considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing linecutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service)．
Markets and queues—paying and waiting—are two different ways of allocating things，and each is appropriate to different activities. The morals of the queue, “First come，first served，” have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.
The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it's the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.
Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank：“Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It's as if the company is trying to ease our impatience with fairness.
But don't take the recorded message too seriously. Today, some people's calls and answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.
Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other nonmarket ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queuejumping schemes we've considered—at airports and amusement parks, in call centers, doctors' offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.According to the author, which of the following seems governed by the principle “First come, first served”？
| A．Taking buses. |
| B．Buying houses. |
| C．Flying with an airline. |
| D．Visiting amusement parks. |
The example of the recorded message in Paragraph 4 and 5 illustrates ________.
| A．the necessity of patience in queuing |
| B．the advantage of modern technology |
| C．the uncertainty of allocation principle |
| D．the fairness of telephonic services |
The passage is meant to ________.
| A．justify paying for faster services |
| B．discuss the morals of allocating things |
| C．analyze the reason for standing in line |
| D．criticize the behavior of queue jumping |

Some people will do just about anything to save money. And I am one of them. Take my family's last vacation. It was my sixyearold son's winter break from school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York, so I had to get back. But that didn't mean my husband and my son couldn't stay. I took my ninemonthold and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport to “earn” more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a bigtime bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made a living looking for the best deals and exposing (揭露) the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.Why did Delta give the author's family credits?
| A．They took a later flight. |
| B．They had early bookings. |
| C．Their flight had been delayed. |
| D．Their flight had been cancelled. |

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.What is the author's opinion on cramming?
| A．It leads to failure in college exams. |
| B．It's helpful only in a limited way. |
| C．It's possible to result in poor memory. |
| D．It increases students' learning interest. |
Much later that night, the question of why I'd stopped for that light came back to me. I think I stopped because it's part of a contract(契约)we all have with each other. It's not only the law, but it's an agreement we have, and we trust each other to honor it: we don't go through red lights.
Trust is our first inclination(倾向)．Doubting others does not seem to be natural to us. The whole construction of our society depends on mutual(相互)trust, not distrust. We do what we say we'll do; we show up when we say we'll show up; and we pay when we say we'll pay. We trust each other in these matters, and we're angry or disappointed with the person or organization that breaks the trust we have in them.The event made the author strongly believe that________.
| A．traffic rules may be unnecessary |
| B．doubting others is human nature |
| C．patience is important to drivers |
| D．a society needs mutual trust |
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet's water. Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink. Animals that don't have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them....If pets are left on their own outdoors in cold weather, they may ________.
| A．run short of clean water |
| B．dig deep holes for fun |
| C．dirty the snow nearby |
| D．get lost in the wild |
