    Nature is full of wonderful plants and animals that are connected to our lives in many different ways.

    Nature's Gifts for Humans

    Nature doesn't just look nice—it also gives us many important things. Many plants give us food directly, like apples from apple trees and rice from rice fields. For example, silkworms (蚕) make silk, and then we use silk to make soft and beautiful clothes.

    Useful and Long-lasting Plants

    Redwood trees can grow to over 100 meters tall and weigh hundreds of tons. Bamboo grows really fast and can be made into many things, like chairs, baskets, and musical instruments. In some Asian countries, people often plant ginkgo trees. These trees can live for thousands of years, and their leaves are even used to make some kinds of medicine.

    Small Animals, Big Helpers

    Small animals play a big role too. Butterflies with colorful wings help flowers by carrying pollen from one to another. Bees make honey in their honeycombs, which people love to eat. Frogs are helpful too because they eat insects that feed on crops (庄稼). A frog can eat thousands of bad insects each year! This helps farmers grow healthy food for us all.

    Small Wonders in Nature

    When we go for a walk in nature, we might see mushrooms under leaves or lotus flowers in the lakes. If we look closely enough, we might also find wild strawberries growing in the grass or pretty roses by the roadside.

    All of these plants and animals are connected in the ecosystem. This is why we must protect nature.

    A. This process called pollination helps plants make seeds (结籽).

    B. However, not everyone understands their importance in the world.

    C. They help clean the air and are used to build houses.

    D. Let's explore some of these amazing connections!

    E. Some animals also provide (提供) us with useful things.

    F. Without them, our planet would lose its balance.
