The US plans to extend its endangered species protection to lions in Africa．US Fish and Wildlife Service(FWS)will classify lions in southern and eastern Africa as threatened．The move will place tighter restrictions on the import of lion“trophies”，such as paws or heads．
While the US cannot regulate hunting in other countries，the move is significant because around half of a11 lion hunting in Africa is conducted by Americans．According to FWS data，more than 5，600 lions have been killed and imported by American hunters over the past decade．
Under the new FWS rules，bringing lion parts to the US will be banned in most circumstances if the animal is from a country where lions are endangered．Hunters will have to show the trophies were“legally obtained”from countries that have“a scientifically sound management program that benefits the subspecies in the wild”·
This regulation is expected to place a far greater burden of proof upon hunters who claim that the money from lion hunting has been used to help communities in Africa and the overall conservation of lions．The persistent downward trend in lion numbers，due to habitat loss and hunting by locals and foreign tourists，suggests there has been little conservation benefit from organized hunts．
An international study，published in September，found African lion numbers have decreased by half since 1993，with a further 50％decline expected over the next 20 years for populations in west，central and east Africa·
“The lion is one of the planet’s most beloved species and an irreplaceable part of our shared global heritage，”said Dan Ashe，director of the FWS．“If we want to ensure that healthy lion populations continue to wander around the African savannas and forests of India，it’s up to all of us—not just the people of Africa and India—to take action．
1.Why will lions be classified as endangered in southern and eastern Africa?
A．No lion is protected in Africa．
B．Lion trading has been banned．
C．Its numbers have been decreasing．
D．Both locals and tourists hunt lions．
2.Where do most of the lion hunters come from?
A．Southern Africa．B．America．
C．Eastern Africa． D．India．
3.What may be the result of the move ?
A．The import of lion parts will be strictly limited．
B．Lion-hunting will be illegal all over the world．
C．Communities in Africa will benefit a lot．
D．Lion parts will not be legally obtained．
4.What does Dan Ashe really want to tell us in the last paragraph?
A．Almost everybody loves lions．
B．It’s everyone’s duty to protect lions．
C．Lion populations will increase rapidly．
D．Measures must be taken to keep lions fit．

LONDON (Reuters) Ecotourism 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 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.
Transmission 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 colorists 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
