They have four chances to5the ball ten yards (码). They can6and throw it. If they move the ball ten yards, they can try to move it7ten yards.8they move it to the end of the field, they can get six points.

    It is difficult to move the9. Eleven men on the other team try to stop the man with the ball. If he doesn't move the ball ten yards, his team kicks the ball to the other team.10university wants its own team to win. Thousands of people come to watch. They all shout for their11teams.

    Young men and women come on the field to help the people shout more. Each team plays 10 or 11 games each12. The season begins in September and ends in November. If a team is very good, it can play another game13the season ends. The14teams play again on January 1st, the first day of the New Year.

In San Francisco, there is a special group of volunteers. They call themselves Friends of the Urban (城市的) Forest (FUF). These volunteers want to {#blank#}1{#/blank#}. Every year, the FUF plants nearly 1,000 trees.

The FUF welcomes new volunteers all year round and in all parts of its work. On Weekend Planting Days, FUF volunteers work with common citizens (市民) to plant trees. The planting usually runs from 9 a.m. to 1 p.m. After the work is done, everyone {#blank#}2{#/blank#} over a community lunch.

On Thursday Planting Days, the FUF plants "replacement (替换) trees". As their name suggests, these trees replace trees {#blank#}3{#/blank#}. Planting Leaders are very experienced volunteers.

Autumn is a good season to do sports, because in summer it is too hot. But what you feel is quite dif-ferent from what your body feels. Your body works more slowly, so it is easy for you to be hurt(伤害)when doing sports. Here is some advice.

Drink water. It is often very dry in autumn and your body loses water easily. So it is good to drink500mlof water two hours before you exercise. But be careful you cannot drink water as soon as(一旦)you finish your exercise. Just do it about 15 minutes after that.

Warm up your body. Before you do any sport, remember to do some warming-up activities such as walking or morning exercises to get your body ready for the sport.

Have outdoor activities. It is cool outside your door and the air is much better. So outdoor activities like climbing the hills, riding the bike and running or jogging are much fun. These can help you lose more fat, get you relaxed(放松) and help you work well.

Do not eat too much after the sport. If you cannot control your mouth, it is better not to do any sport. You can have some fruit or vegetables if you really want to eat something.

Pictures are falling off the walls. Lights are waving. Bed is shaking. Everything is moving. What's going on? It's an earthquake. 

Earthquakes are horrible disasters(灾难）and some of them are destructive, The top layer of the earth is made up of huge pieces of rock. They move past each other all the time along fault lines(裂纹线）. But sometimes two pieces get stuck together. When they finally move away from each other, they move suddenly. And this makes the land above them shake. This is the most common cause of earthquakes. 

During a small earthquake, you will feel a little shaking. But during a strong one, you will be thrown about. A strong earthquake is very horrible. Cracks will appear on the ground and windows and doors will break. Buildings will even fall down. So watch out! I f an earthquake happens at sea, it can make big waves called "tsunamis" (海啸). When these waves reach land, they can destroy villages. 

Earthquakes are measured on a scale of 0-9. It is called the Richter scale. A size 9 earthquake is the strongest and most dangerous. Since 1900, more than two million people have died in earthquakes. In 1976, a size 7. 8 earthquake hit Tangshan, China. It killed more than 240, 000 people!

Many earthquakes happened in China, so it is important for us to know what to do when an earthquake hits. Here are some tips on how to stay safe in an earthquake. 

Indoors

※Hide under a desk or bed. Stay away from windows and anything that could fall on you. 

※Do not get into a lift during an earthquake! When an earthquake has ended, stay under the desk until it is really safe to get up. 

※Open a window and get out of the building quickly if the gas line in your house is broken. 

Outdoors

※Move away from buildings and street lights. 

※Do not run outside if you are in a shop and far from the door. 

※Make sure you wear shoes after an earthquake. There may be broken glass on the ground. 

According to a study in Nature Climate Change, the population of polar bears will be in serious drop by the year 

2080. The cause is melting(融化) sea ice. Without ice, the bears must walk on the bank which is away from their main food source. That means the animals will be in danger because of lacking food.

" There's not enough food on land to support a polar bear population." Doctor Smith, the study's lead writer said. Lacking of food induces another problem. Mother bears may not be fat enough to produce milk for their babies. Some bear populations could stop having babies, leading to a rapid drop in numbers.

Arctic(北极) sea ice usually melts in the spring and summer, and then grows in the winter. But now, the ice is taking longer to grow back. Weather reports say the Arctic is warming twice as fast as the rest of the planet. Ice here has reduced 13% every 10 years since the 1970s. The Arctic is home to about 25,000 polar bears. Scientists have known that the animals are in danger.

But the study also notes that it is still possible to slow Arctic melting. The world can reduce the burning of fossil fuels(石化燃料) and lower the greenhouse gas." Saving the polar bears is up to us, I believe that there is hope. But humans need to act quickly to turn that hope into a reality." Doctor Smith said.
