    We can get the weather report on the Internet. We can also know it by watching TV or listening to the radio. But how can we know it without TVs, radios or the Internet? Now let me tell you some other ways.

    One way is to study the clouds. In fact, the higher the clouds are, the better the weather will be; the lower the clouds are, the worse the weather will be. If the thick and fluffy(轻软状的) clouds get bigger early in the day, then it will rain. If a sudden, cool and dark thunder­cloud appears, then a storm is about to come.

    Colours in the sky tell us about the weather, too. A golden ring around the moon warns us that a storm is on the way.

The rainbow has a message, too. If the sun is in the west and the rainbow is in the east, the rain will be moving away from you.

    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.

    In the Charles F. Johnson Elementary School in New York, there is a special radio. It gives people warnings about bad weather.

    One day, there came a sound from the radio. This sound brought the piece of news: a heavy storm was coming. William Tomic, principal(校长) of the school, asked teachers to bring children indoors and put them in a safe place at once.

    Minutes later, the storm came. However, because of the warning of the radio and the quick work of the principal, no one was hurt.

    "The radio really did work very well.(A)(我们对它的工作感到很满意), "William Tomic said. "The parents were happy as well."

    The U. S. government hopes there will be more such successful stories. It plans to give this kind of radio to all 97, 000 public schools in the country.

    Every year, more than 10, 000 big thunderstorms, 2, 500 floods, 1, 000 tornadoes(龙卷风) and some hurricanes(飓风) take place in the U. S., so the warning radios are very useful. They not only give people warnings about bad weather, but also give warnings about other dangerous  things.

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:
