What are wildfires
A wildfire is a fire. It burns（燃烧）for a long time in forests, grasslands and other natural places.
Why are wildfires dangerous
Wildfires can be very dangerous. Wildfires make the air dirty. They can make people and animals sick. The fires burn the plants, so some animals can't find food. In Australia, koalas are badly hurt because they are slow. They can't run away.
How can wildfires help nature
Wildfires can also be good for nature. The fires can clean up dead（枯萎的）leaves.When old trees burn,the ashes（灰烬）make the ground rich-it becomes healthy and full of good things. These can help young plants to grow fast and strong. After the fire, new green grass and young trees start to grow because sunlight can touch the ground. Some plants need fires to open their seeds. Many animals come back to find food and homes. Wildfires can help the forest start a new life.

Henry David Thoreau’s Friend: Nature
Henry loves to walk in the forest near his home. He listens to the trees. He watches the rivers. He picks up leaves, seeds and flowers and puts them into his pockets.
Every morning, Henry steps outside and goes to Walden Pond. He walks slowly by the water. He stops and looks around. Skunk cabbages dance in the snow. Tiny ants wake up under warm leaves.
Henry writes what he sees in his notebook. Frogs sing to show spring is coming. Flowers grow on trees. The weather gets warm. The ice melts into water in the rivers.

What is huinantian It is a special kind of weather in South China in spring. It happens when the weather becomes warmer. Before it comes, there are usually a few cold days, with a temperature under 12 ℃. After the cold air goes away, warm air quickly comes and gets cool. This makes a lot of water vapor（水蒸气）. So you can see small water drops on windows and walls.
Because of the humid weather, everywhere gets wet, clothes hardly turn dry, and things get moldy（发霉的）.It also makes people feel tired and get ill. Catching a cold is common at this time because the temperature changes quickly.
Although the weather causes lots of problems for people, it can be useful. Because of the humid weather, plants can grow well with much water and warm air.
What can we do when huinantian comes First, you can close the doors and windows.Mornings and nights are important times to stop wet air from getting into rooms. Also, you can put newspapers on the floor, and at the door to take in（吸收） water and wet air.

二、阅读Jim给妈妈的信，完成任务。
Dear Mum,
How is it going Is everyone well at home I miss you all.
Everything is well. I really enjoy my life here on Uncle Bill's farm. It is such a nice place that impresses me deeply.
The farm is in a valley between two hills. There is a stream around the farm and the water flows happily to the valley. There are ducks swimming gracefully on the water. There are green apple trees on the two sides of the stream and beautiful birds rest in the trees.
On the green land, the chickens are looking for worms in the green grass.The cows are mooing leisurely. The horses are whispering gently, andthe pigs are crowding together, enjoying their food.
There are no wide roads, no tall buildings, no noisy traffic, but everything is so beautiful. I can feel the sweet taste of the wind and the brilliant sunshine. I hope I can come here again next year! Uncle Bill really hopes that I can stay here longer.
Best wishes to you all!
Yours,
Jim
