单选题Questions are based on the following passage.
The huge growth of global "ecotourism" industry is becoming an increasing concern for con servationists with mounting evidence that many wild species do not respond well to contact with human beings. Over exposure to tourists has been linked to stress, abnormal behaviour and adverse health effects in species such as polar bears, dolphins and gorillas, says a report in New Scientist.
"While regulated ecotourism can help conservation efforts by encouraging people to manage endangered species and their habitats, many projects are poorly designed and unregulated," it says.
"Many ecotourism projects are unaudited, unauthorized and merely hint they are based on environmentally friendly policies and operations."
Ecotourism is growing by 10 to 30 percent a year and an estimated 20 percent of tourists are thought to visit a conservation-based project. Philip Seddon, of the University of Otago in New Zealand, said that although most tourist projects conformed to basic guidelines on land use and not scaring wildlife, their full impact was rarely considered.
"Transmission of disease to wildlife or subtle changes to wildlife health through disturbance of daily routines or increased stress levels may translate to lowered survival and breeding" he said. Re- search at the University of Auckland has shown that dolphins become restless and overactive when many tourist boats are present. When three or more boats are near, the dolphins rest for 0.5 percent of the time, compared with 68 percent when they are accompanied by a single boat. The findings are backed up by studies of dolphins in Britain. Researchers at the University of Manitoba in Canada have found that male polar bears were easily disturbed by tourist vehicles, with a possible effect on their heart rate and metabolism. That could reduce body fat levels and fitness, which are critical for survival.
In Africa, gorillas have picked up parasites introduced to their habitat by tourists and mongooses have caught lung diseases from human beings. Experts said that the answer to the problems was better regulation and supervision of ecotourism. The Galapagos Islands, where visitor numbers are strictly controlled, is a good model.
What can we know from the first paragraph?

A．Conservationists are strongly in favour of the development of "ecotourism" industry.
B．It is found that some wild species could be badly affected by over contact with people.
C．The huge growth of global ecotourism industry has a very bad effect on the environment.
D．Ecotourism is good for encouraging people to protect endangered wild species.

参考答案B

解析:全球“生态旅游”产业的飞速发展越来越受到自然保护主义者的关注，有越来越多的证据表明，许多野生物种在与人类的接触中反应不佳。《新科学家》的一篇报道指出，北极熊、海豚以及大猩猩等物种所表现出的压力、异常行为和不良的健康影响与过多接触游客有关。
这篇报道指出：“规范的生态旅游通过鼓励人们监管濒危物种促进环保，但是很多项目设计不够完善，缺乏管理。许多生态旅游项目未经审查，也没有得到授权，只是说它们依据环保政策和环保运作方式。”
生态旅游产业正以每年10％到30％的速度增长。据估计，20％的游客会选择游览环保项目。新西兰奥塔戈大学的菲利普．塞登说．虽然大多数旅游项目的开发符合土地使用制度规定和不惊扰野生动物的基本指导方针，但却很少考虑整体影响。
他还指出，“将疾病传染给野生动物．或者干扰它们的日常生活习惯使得野生动物的健康发生微妙的变化或者不断地增加它们的压力，这些都可能会致使野生动物的生存率和繁殖率下降。”奥克兰大学的研究表明，当许多旅游船出现在海豚周围时，它们会变得不安和异常活跃。当它们附近有三艘或更多的船时，海豚的休息时间仅占0．5％．相比之下．附近只有一艘船时它们的休息时间则占68％。英国有关海豚的研究证实了这些研究成果。加拿大曼尼托巴大学的研究人员发现，旅游交通工具很容易惊扰雄性北极熊，这可能会影响其心跳频率和新陈代谢,从而降低其身体脂肪厚度和影响健康，甚至可能会致命。
非洲的大猩猩身上已经长出寄生虫，这些寄生虫是被游客直接带入其栖息地的；猫鼬也已经患上由人类传入的肺病。专家指出，解决这些问题的办法是更好地规范和监管生态旅游。加拉帕格斯群岛就是一个好的典范，在那里，游客的数量受到严格限制。
解析
细节题。根据第一段many wild species do not respond well to contact with human beings．Over exposure to tourists has been linked to stress，abnormal behaviour and adveme health effects in species …可知野生物种在与人类的接触中反应不佳，受到不良影响。因此，正确答案是B。
