Endangered Species Reading:Polar Bear Makes the List

In Spring 2008,the polar bear was placed on the endangered species list. According to the Endangered Species Act,an endangered species is an animal that is likely to face extinction in its natural habitat. __26__ The ESA defines a threatened species as one that is likely to become“endangered”in the foreseeable future.

The polar bear is the first animal that has been classified as endangered due primarily to global warming. __27__ Heating homes,driving cars,and burning garbage all require fossil fuels that lead to global warming.

The polar bear's habitat is more vulnerable to global warming than many other species. Polar bears live mainly on the sea ice in the Arctic. __28__ When the ice melts many polar bears move to land and live off their stored fat.In the Arctic, global warming is causing the ice to melt slightly earlier and form slightly later. This results in a shorter feeding season for the polar bear. Some risk their lives to find ice.If they have to swim too far they will drown from exhaustion and hunger.

__29__Every species of plant,animal,and insect there is threatened by global warming. Nevertheless,environmentalist groups such as the World Wildlife Fund often study large carnivores in order to assess the health of an ecosystem (生态系统) . __30__ In addition, donations are more commonly offered for the protection of large animals such as bears or elephants. People in general are less interested in conservation efforts that protect small wildlife, such as plants or insects. However,by using donor money to protect the habitat of the larger animals (ex.reforestation programs ) ,entire ecosystems can be protected.

It is important that animals such as the polar bear make it onto the endangered species list.

Once they are on the list there are laws that protect these animals from being hunted for food or sport. Agencies also receive money and tools to protect the habitat and recover the species. The goal of removing the animal from the list is often achievable.In fact,it is rare for a species to go extinct after they make the list. Sadly many species do go extinct while waiting for consideration.

 

A. But adding polar bears to the nation's list of endangered species,as some are now proposing, should not be part of those efforts.

B. Global warming is caused by carbon dioxide and other greenhouse gases that become trapped   in the atmosphere.

C. The Arctic food chain relies on the polar bear.

D. It is not only the polar bear that is at risk in the Arctic.

E. This is where they hunt for fish and build up fat reserves.

F. Polar bears have been categorized as a“threatened”species.

The workers' participation (参与 ) in management might save a plant from closing down.

Two People,Two Paths

You must be familiar with the situation:Dad is driving. Mum is telling him where to go.He is __31__that they need to turn left.But she says it is not for another two blocks. 

__32__has the better sense of direction? Men or women? They both do,a new study says,but in different ways. Canadian researchers have found men and women have __33__ methods of finding their way. Men look quickly at landmarks and head off in what they think is the right direction.

Women, however,try to picture the whole route in  34   and then follow the path in their head.

“Women tend to be more detailed,while men  35  to be a little bit faster and a little bit more intuitive (直觉感知的 ) ”,said Edward Cornell.

In fact,said Cornell,“sense of __36_”is not one skill but two.The first is the“survey method” . This is when you see all area from above,such as a printed map.You can see,for example,where the hospital is,__37__the church is and that the supermarket is on its right.The second skill is the “route method”,this is when you use a series of directions.You __38__from the hospital,then turn left,turn right,go uphill——and then you see the supermarket.Men are more __39__ to use the survey method while women are more likely to use one route and follow directions. Both methods work, and __40_ is better

A.direction	B.who	C. sure
D.start	E.likely	F.what
G. where	H. neither	I.different
