The Amur leopard is a critically endangered species，with an estimated population of fewer than 100 individuals. The leopards，characterized by their beautiful golden coat with large dark rosettes，are native to the forests of the Russian Far East and northeastern China. They are often considered the rarest big cats in the world，and their numbers have been declining rapidly due to the habitat loss，poaching(偷猎)，and the changing climate.
Habitat loss is one of the primary threats facing the Amur leopard.As logging and agricultural activities continue to expand in the region，the leopards are losing their once vast and undeveloped forests.The loss of habitat results in a decrease in prey populations，making it increasingly difficult for the leopards to find enough food.In addition to the habitat loss，poaching poses a significant threat to the survival of the species.Amur leopards are often hunted for their unique and attractive fur，which can fetch high prices on the black market.
Climate change is also impacting the Amur leopard population.As temperatures rise，the forests they rely on are undergoing changes，forcing the leopards to adapt to new conditions.This puts additional stress on an already struggling population.
Conservation efforts are underway to try and save the Amur leopards from extinction.Government established the Land of the Leopard National Park，which covers a significant portion of the leopard's habitat.This protected area is essential in ensuring the survival of the species.Additionally，organizations like WWF are working to curb(遏制) poaching and promote sustainable forestry practices in the region.
Despite these efforts，the future of the Amur leopard remains uncertain.It is crucial that we continue to work towards the preservation of this magnificent creature，or we risk losing it forever.

The Amur leopard is a critically endangered species，with an estimated population of fewer than 100 individuals.The leopards，characterized by their beautiful golden coat with large dark rosettes，are native to the forests of the Russian Far East and northeastern China.They are often considered the rarest big cats in the world，and their numbers have been declining rapidly due to the habitat loss，poaching(偷猎)，and the changing climate.
Habitat loss is one of the primary threats facing the Amur leopard.As logging and agricultural activities continue to expand in the region，the leopards are losing their once vast and undeveloped forests.The loss of habitat results in a decrease in prey populations，making it increasingly difficult for the leopards to find enough food.In addition to the habitat loss，poaching poses a significant threat to the survival of the species.Amur leopards are often hunted for their unique and attractive fur，which can fetch high prices on the black market.
Climate change is also impacting the Amur leopard population.As temperatures rise，the forests they rely on are undergoing changes，forcing the leopards to adapt to new conditions.This puts additional stress on an already struggling population.
Conservation efforts are underway to try and save the Amur leopards from extinction.Government established the Land of the Leopard National Park，which covers a significant portion of the leopard's habitat.This protected area is essential in ensuring the survival of the species.Additionally，organizations like WWF are working to curb(遏制) poaching and promote sustainable forestry practices in the region.
Despite these efforts，the future of the Amur leopard remains uncertain.It is crucial that we continue to work towards the preservation of this magnificent creature，or we risk losing it forever.

A．It is as big as a cat.

1．B [细节理解题。根据第一段中的“The Amur leopard is a critically endangered species，with an estimated population of fewer than 100 individuals.”可知，据估计，远东豹的数量不足100只，由此可知，远东豹有灭绝的危险。]
2．A [推理判断题。根据第二段中的“Amur leopards are often hunted for their unique and attractive fur，which can fetch high prices on the black market.”可知，远东豹的皮毛在黑市上可以卖到高价，由此可知，人们猎杀远东豹的主要原因是为了赚钱。]
3．C [细节理解题。根据第三段“Climate change is also impacting the Amur leopard population.As temperatures rise，the forests they rely on are undergoing changes，forcing the leopards to adapt to new conditions.This puts additional stress on an already struggling population.”可知，气候变化也是影响远东豹数量的因素。由此可知，气候变化增加了远东豹数量的额外压力。]
4．C [推理判断题。根据第四段中的“Conservation efforts are underway to try and save the Amur leopards from extinction.Government established the Land of the Leopard National Park，which covers a significant portion of the leopard's habitat.”可知，Land of the Leopard National Park是一个政府为了避免远东豹灭绝而建立的远东豹的保护区。]

1．C [他们的想法是，这样他们就能够返回到他们感兴趣的地方了。此处意为“使感兴趣”。故选C。]

9．have been preserved [考查动词的时态、语态和主谓一致。根据上文so far可知，应用现在完成时，且主语与谓语动词构成被动关系，应用现在完成时的被动语态，主语为a large number of coastal wetlands，助动词用have。故填have been preserved。]
10．valuable [考查形容词。修饰空后的名词habitats，应用形容词valuable，作定语。故填valuable。]
