1 . Sunshine, beaches and coconuts (椰子) —these are why people usually go to Hainan. But more than a good place for travelers and foodies, it’s also a wonderland of plants and animals.

Hainan Tropical Rainforest National Park in the south-central part of Hainan Island, has the most and well-kept tropical rain forests in China. President Xi Jinping visited it in April, 2023. The national park covers 4, 269 square kilometers, or one-seventh of the island. More than 95percent of the park is virgin (原始的) forest and is home to 3,653 species (种类) of vascular plants and 540 species of terrestrial vertebrates.

The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地) . They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection.

Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather.

With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world.

As we all know, trees are useful to humans and animals. They give living places and food to wild life. They take in carbon dioxide (二氧化碳) and give off oxygen (氧气). They also make our world more beautiful. Let’s know about some kinds of trees in the world.

3 . Parts of a Plant

There are more than 400,000 kinds of plants on Earth. Some plants are as big as tall buildings; others are as small as rice. Plants are key parts of the food circle. They play an important part in the nature because they give out oxygen—the gas that all animals need for breathing.

What is a plant?

Most people have no difficulty finding the differences between an animal and a plant. That is because animals can move around, but plants can’t. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells (细胞). Unlike animals, plants make their own food by photosynthesis (光合作用). Most plants have roots, stems, and leaves, and most plants reproduce by growing flowers and making seeds. All plants need energy to stay alive and grow, and they get it from sunlight instead of food.

How does a plant grow?

Most animals grow in a certain way, and genes control their growth. That is to say, even when they are small, it’s easy to know what they will look like after they grow up. Plants are different. Their growth is controlled by genes too, but their final shape also depends on where they live. For example, a tree can be big and round if it grows up in an open space, but much taller and thinner if it grows in the woods with other trees all around. Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment.

5 . Trees are one of the oldest “citizens” of our earth. They keep our air clean, reduce noisy pollution, improve water quality and provide food and building materials.

     Just like us, trees change a lot as they grow. At 1 to 3 years old, many trees learn how to p    1    themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large deep green leaves so that they can catch enough sunlight and change it into their food and e    2    .

When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges (挑战) later in life. At the age of 15, trees become young adults. They grew s    3     and begin to produce flowers and fruit.

It is not until the tree is 20 to 25 years old that it becomes a r    4     adult. The tree reaches its largest size. Not only does the adult tree gives us shed, oxygen and natural beauty; it is also a great place for a tree house, or a place for us to nap or read a book or listen to music. If the adult tree receives proper care, it will continue to live h    5     for many years.

Gradually trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow (空心的) or part of it dies, it provides a home for small animals, and is also a source of food for many o    6     animals.

In many ways, the life of a tree is similar to our own life especially. When looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge. Enjoy every minute of it and take care of the trees!

6 . Every year, when the Dragon Boat Festival comes, Chinese people often put a kind of plant on the door. It is called wormwood (艾草).     1     On the other hand, its special smell can also keep insects away from rooms.

Wormwood is well-known because it can treat a great number of illnesses. Hundreds of years later, in Qichun, Hubei Province, it is still helping people. Recently, Qichun is busy preparing for the World Wormwood Industry Show (艾草产业展会).     4     And it will be good for TCM and the traditional Chinese culture.

Wormwood is becoming the main-industry in this area.     5     At the same time, wormwood is becoming more and more famous around the world as a kind of traditional Chinese medicine.

Plants, more than just pretty to look at, also give us fruits, vegetables and food. Some plants even provide materials for medicine or building things. But do you know that plants can do something even more     1     (amaze)? They can make our homes, schools and workplaces much     2     (healthy).

We spend a large part of our day indoors. The air quality inside buildings is often very poor and can make us feel sick,     3     (cause) sore eyes and throats, and even making it hard for us to breathe. When the air inside buildings     4     (get) really bad, people even call them “sick buildings”.

Luckily, plants, like nature’s     5     (hero), have a magic power fighting against bad air. Plants breathe in carbon dioxide (CO₂) and breathe out oxygen (O₂) which we humans need to live. They can also add moisture (水分，湿气) to the air if it’s too dry, making it more comfortable for us     6     (breathe).

Besides, scientists have discovered that plants have the ability to take     7     harmful chemicals, making the air around us safer to breathe. They set up a     8     (complete) closed building called “bio-home” for experiments.     9     they added plants, the air inside was full of chemicals. But after they added plants, the air got much cleaner. To make the air inside even better, the scientists used different kinds of plants. After a while, the building wasn’t a “sick building” any more. People could go inside without feeling unwell.

So you see,     10     fantastic plants are! Next time you see a plant, remember all the amazing things it can do for us!
