Nature has provided us with many kinds of resources. It is like a great magician(魔术师), creating wonders on Earth. One of them is the Amazon rainforest, the world's largest and home to millions of plants and animals. Nicknamed" the lungs of our planet", it produces about one-fifth of Earth's oxygen. However, this wonderful natural wonder is now in danger.
Thousands of fires have broken out in Brazil, endangering much of the rainforest. These flames have lasted several weeks and are believed to be the "most intense" in almost ten years, according to BBC News.
The Amazon has seen a large number of fires in 2019. Between January and August, there were over 74,000 fires – the highest number since 2013, the BBC reported.
Forest fires are common during the dry season, which runs from July to October. They are usually caused by natural events like lightning. However, most of the fires this year are believed to be caused by farmers, who use fire as a traditional part of tropical agriculture(农业) to clean land, reported CNN.
"It's the best time to burn because the plants are dry. Farmers wait for the dry season and they start burning and clearing the areas so that their cattle can have grass," wrote CNN meteorologist Haley Brink.
The disaster has raised concern(关注) around the world. The Amazon rainforest is important for preventing climate change, said the BBC, absorbing millions of tons of carbon annually. When trees are cut down or burned, the rainforest's ability to absorb carbon is reduced.
Brazilian climate expert Carlos Nobre told Reuters he's worried. If more than 20 percent of the ecosystem is destroyed, the Amazon rainforest could reach a "tipping point (临界点)", where the thick jungle will turn into a tropical savannah(大草原).
Nobre warned that it is not far off, with between 15 and 17 percent of the rainforest having already been destroyed.
The Brazilian government has sent soldiers to fight the fires. Many people have offered their support and called for recovery efforts. For example, Tim Cook, CEO of Apple, said he wanted to donate money and US Actor Leonardo DiCaprio's environmental charity, Earth Alliance, created a donation fund to help deal with the disaster.
The public are also encouraged to donate to charities concerned with rainforest protection. "Every little bit helps in a bad situation like this," commented Gizmodo.

Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?
{#blank#}2{#/blank#}
For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we are awake.
{#blank#}3{#/blank#}
There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest as it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired. But a short deep sleep can be very restful.

Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give command to attack!

Normally when we go to sleep, our “ sleep center” blocks off nerves so that both our brain and our body go to sleep. One prevents us form wanting to do anything and the other makes our internal organs and limbs go to sleep. But someone will fall asleep (brain sleep) and keep on marching, because his body is not asleep!
