听力原文： Whale watching is a growing ecotourism industry around the world. It can be emotional, educational and an important part of local economies, offering a unique opportunity for people to appreciate the magnificence of whales in their natural habitat and to help motivate people to protect these animals and their environment. (26) Additionally, much of what scientists know about whales is a result of research conducted while they are aboard commercial whale watching vessels.
However, unregulated whale watching can also lead to problems, including threats to the animals' well-being and negative impacts on fragile coastal environments. In addition to increasing numbers of whale watching vessels, in many parts of the world, newer boats are capable of going much faster than in the past, with the increasing likelihood that whales will be hit by boats. The faster a vessel moves, the less likely the operator is to see a distant whale, and the less time they have to react once they do spot an animal. (27)Also researchers have found that if whales are feeding or socializing, they are less likely to react to an oncoming vessel and can be hit.
In response to this problem, whale watching groups, government agencies and private advocacy groups have established codes of conduct for whale watching. Under these rules, approaching an area of known whale activity should be done slowly and with caution, stopping to survey the area. (28)In addition, approach parallel to the whales and travel at the same speed as the slowest animals. Stay at least 100 meters away and don't leapfrog into the path of the whales. Preferably, there should only be two vessels at a time viewing a group of whales.

听力原文：W: Oh, it is terrible! Abroad Aero lines Argentina's flight 386. 386 passengers were given prepared food on their way (20)from Buenos Aires to Los Angeles.
M: Then what happened？
W:A few days after arriving in Los Angeles. (19)one passenger died, and 74 others were seriously ill.
M: What is the reason for that？
W: According to Dr. Phillips, it was the highest single outbreak of cholera in the United States this century, and the airline passengers were the victims of this new epidemic of cholera, a disease not seen in Latin America since 1895. they were just a few of the more than one million people affected in the 20th centuries, including at least 10,000 who died in the following three years after 1991.
M: (19)Cholera？ To the best of my understanding, that disease has been dead for some time now.
W: (19)But it has come back. Dr. Phillips says that cholera is by no means the only old infections on the comeback, and it is just one of the major infections that are fighting back fiercely against man's attempts to control them.
M: (19)But what are the reasons for the comeback of so many dead diseases？
W: Phillips says a single reason can't explain why a new disease appears or an old one returns, and usually a combination of factors are involved.
M: What kind of specific factors？
W: In his book Plagues on Our Doorstep Dr. Phillips presents some reasons.
M: What are they？
W: First, (21) international travel and commerce. The cholera abroad flight 386 and mosquitoes living in imported tries are examples of these. Second, (21) technology and industry. For example, the technology in Britain's processing industry was a likely contributor to the emergence of mad cow disease. Third, (21)the breakdown of public health measures. Declining health resources have resulted in the erosion of once highly-valued health service.
M: Well, that's just unbelievable!
