in the Arctic.He was there to take pictures for National Geographic.Finally,he saw something big and white.It was a polar bear,swimming towards him in the icy water.Paul lay down on the ice to get a better photo,but the polar bear jumped out of the water and tried to attack him!Luckily for Paul,the ice cracked or broke and the bear fell back into the water.The polar bear wasn’t so lucky.It couldn’t get a meal and had to swim farther away to find food.To understand the polar bear’s problem,you need to know two things about the Arctic.First,the Arctic is mostly ocean.Second,ice covers a lot of the Arctic Ocean.In winter,the ice forms a thick,white sheet,but in summer,the ice becomes thinner and breaks into pieces.Sea ice is the key to survival for Arctic animals.However,because of global warmin9,Arctic temperatures are rising and polar ice is melting.Polar bears need ice to hunt seals,their favourite meal.They stand on the ice waiting for the seal to come up for air.As Arctic ice melts,polar bears have to swim farther to find ice floes,or large pieces of floating ice.Sometimes,bears have to swim more than 200 km to find an ice floe.Some bears cannot swim that far and sadly they drown.On his last trip,Paul Nicklen saw three dead bodies of polar bears.Before global warming threatened Arctic ice,a dead bear was a rare sight.Paul is sad to see the dead bodies.Wildlife experts think global warming will have a terrible effect on polar bears.In the future,polar ice will continue to shrink and endanger the bears.Some scientists believe 65 percent of the world’s polar bears will disappear by 2050.In other words,polar bears are in great danger.1.The main idea of the passage is that ________.A.polar bears are amazing swimmersB.Arctic temperatures are risingC.global warming is endangering polar bears2.The polar bear that tried to attack Paul was unlucky because ________.A.Paul swam away     B.it was on an ice floe    C.it couldn’t eat Paul3.According to the passage,polar bears hunt seals by ________.A.waiting on the ice    B.waiting in the water    C.drowning the seals4.From the passage,Paul Nicklen is maybe a ________.A.scientist         B.photographer          C.psychologist5.We can infer(推断)that polar bears ________.A.won’t have any food in 2050B.will all die before 2050C.cannot find food easilyBNational parks are large areas of public land.They give a safe home for local plants and animals.They help keep the air and water clean.They also give us the best trips.Today,there are nearly 7,000 national parks around the world.Forbes has listed 12 of the most beautiful ones in the world that will surprise you with their amazing landscapes,geographic wonders and colorful plants and animals.The Grand Canyon(大峡谷)National Park of the US is one of the Seven Natural Wonders of the World.It is best known for its size and depth.It is 446 kilometers long,up to 29 kilometers wide.and 1.6 kilometers deep.The immensity of the canyon makes people think big.Every year,about 5 million people visit here.Taking a tour in the South Rim offers visitors the park’s full views,while the North Rim shows beautiful wild flowers.If you love animals,you’ll like the Serengeti National Park in Tanzania.The“Big Five”live here.They are the lion,African elephant,African leopard,black rhinocero and African buffalo.The name“Big Five”came from the five animals that were the hardest to catch.Now they are what people most want to see in the wild.If you visit the park,you should never miss the migration(迁徙)of over 1.5 million wildebeests(角马)and 250,000 zebras every year.This is the most famous site of the park.6.Which is NOT right about national parks according to Paragraph 1？A.Wild plants and animals are protected in

A giant panda can grow up to 1.5  meters long and weigh up to 160kg.

The WWF works to help giant pandas in the wild in many ways.

The corridors let pandas move from one habitat (栖息地) to another to look for food.②People are working very hard to make sure the giant panda does not die out. 1.
