Paul is a photographer(摄影师). He went to the Arctic to take pictures for NationalGeographic(《国家地理》). Finally, he saw a big and white polar bear swimming to him in the icy water.
Paul lay down 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(破裂), 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(海洋). Second, ice covers(覆盖) a lot of the Arctic Ocean. In winter, the ice is thick, 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 warming, Arctic temperatures are rising and polar ice is melting(融化).
Polar bears need ice to hunt(捕捉) seals, their favourite meal. They stand on the ice and wait for the seals 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(淹死).
On his last trip, Paul saw three dead bodies of polar bears. Before global warming threatened(威胁) Arctic ice, a dead bear was a rare sight. Paul is sad to see the dead bodies. Wildlife experts(专家) think global warming will have a terrible effect(影响) 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(消失) by 2050. In other words, polar bears are in great danger.
Li Yang: Good morning, Mathew.
Mathew: Good morning, Li Yang.
Li Yang: There's still smog(烟雾) today. We'll have to go to school with face masks(口罩).
Mathew: According to the news, PM2.5 pollution is the main problem with air pollution.
Li Yang: Yes, and air pollution has done harm to people's health.
Mathew: So the Chinese government and Chinese people must take action to fight it.
Li Yang:
Mathew: Since PM2.5 is mainly caused by vehicles(车辆)and factories, cars with large emissions should not be allowed and factories should be closely watched.
Li Yang: We hope that more and more people will join us in making the blue skies return for good.
Mathew:

All week long, it seems you sit inside at school when it is fine outside. But when the weekend comes, it is very cloudy. There is rain in the weather report, In some ways, you may be right. Scientists studied more than 40 years of weather data(数据) from around the world. It shows weekend weather is different from weekday weather in some places.
Part of the study involved(包括) 660 weather stations in the US. At more than 230 of these places， the weather on Saturday, Sunday, and Monday was different from the weather on Wednesday, Thursday, and Friday. The difference was small, but the pattern was striking enough to make the scientists take notice.
"This kind of weekly rise and fall isn't any natural cycles( 自然周期变化),” the scientists say. Instead, they think that air pollution from human activities makes the weather become different.
