Welcome to the Amazon rainforest. As the largest rainforest in the world, it plays an important role in keeping the balanced ecosystem（生态系统）on the Earth. With an area of around 6 million square kilometers, the Amazon rainforest is more than half the size of China. This area has a great many species（物种）. Actually, one in ten known species in the world can be found here.

Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon. There are different levels in the forest. At the bottom is a system of roots under the ground. Above that is leaf litter on the dark forest floor. The next level is made up of shorter plants with large leaves. Then there are the towering ancient hardwoods, and finally the tops of the trees which are taller than any other level of trees in the forest. Each level of the forest forms its own little world, home to different kinds of living things.

More than 1,300 species of birds and over 400 species of mammals（哺乳动物）hide among the forest’s plant life. This jaguar is one example. While a large number of jaguars survive here, they are only one part of this forest's food chain（食物链）. They feed on at least 87 species, including frogs. These frogs, in turn, feed on insects which eat leaves and fruit.

The Amazon rainforest is a treasure house of species that can be used for food or medicine. What’s more, the Amazon rainforest breathes life into the planet by producing over 20 percent of all the Earth’s oxygen（O₂）. So it is often known as the “lungs of the planet”.

Humans have long tried to predict（预测）the weather. From the hunters of ancient times to today’s pilots, predicting rain or shine can shape people’s life and make a difference.

In 650 BC, the Babylonians tried to predict the weather based on the appearance of clouds. Around 340 BC, Aristotle, a famous Greek thinker and scientist, wrote Meteorologica. It introduced the types of weather, such as rain, cloud and lightning. Aristotle believed that there was water, air and fire around the Earth. It was almost 2,000 years before his ideas were replaced by new ones.

By 300 BC in China, a calendar divided the year into 24 festivals gradually, each festival related to a type of weather, like the Rain Water（the start of the spring rains）, the Waking of Insects（the spring thunder awakens sleeping insects）and so on. That was useful for farmers to plan when to plant and harvest（收获）.

People used lots of ways to predict the weather over the centuries. You might have heard the expressions like “Red sky at night, sailor’s delight”, which suggests a red sky in the evening is followed by good weather. This has a basis in science, as does telling wind direction through smoke from the fire. On the other hand, some thought that if sheep crowded together, it meant rain. But there isn’t any science behind it.

The science of weather prediction really took off in the 1830s with the invention of the telegraph. It sent messages over hundreds of thousands of miles, so weather maps were drawn up and storm systems were studied. The next big step came in the 1920s with the invention of the “radiosonde”, a balloon carrying weather instruments high above the ground to collect information. Experts took the information and built a picture of the weather over the following few days.

Today, supercomputers are used to take data（数据）from the world and process it very fast to work out the weather. For example, they once helped predict where Hurricane Lee, which hit the US and Canada, would land nine days in advance（提前）.
