（一）Forests of the World
Forests are important parts of the natural world. They are home to millions of plants and animals. Tropical rainforests, like the Amazon, stay warm all year and get lots of rain. Deciduous forests have trees that lose their leaves in autumn. Forests help clean the air by taking in carbon dioxide and giving out oxygen. Many people depend on forests for food, wood, and medicine. Sadly, forests are being cut down, which harms the natural world.
( ) 1. Forests are home to many plants and animals.
( ) 2. Tropical rainforests are cold in winter.
( ) 3. Deciduous forest trees lose leaves in autumn.
( ) 4. Forests produce carbon dioxide.
( ) 5. Cutting down forests is bad for the natural world.
（二）Rivers and Lakes
Rivers and lakes are vital to the natural world. They provide water for plants, animals, and people. Many fish live in rivers, and birds often visit lakes to drink and find food. Rivers start from mountains or springs and flow into oceans. Lakes are usually surrounded by land and can be fresh or salt water. Plants like water lilies grow in lakes, and frogs make their homes there. Polluting rivers and lakes hurts the natural world.
( ) 1. Rivers and lakes provide water for living things.
( ) 2. Fish can be found in rivers.
( ) 3. Rivers flow from oceans to mountains.
( ) 4. All lakes are fresh water.
( ) 5. Pollution harms rivers and lakes.

（一）Mountains and Valleys
Mountains are high, rocky landforms that rise above the surrounding area. The highest mountain in the world is Mount Everest. Many mountains are covered with snow, even in summer. Valleys are low areas between mountains or hills, often with rivers running through them. Mountain animals like goats have strong legs to climb steep slopes. Plants on mountains are usually small and tough to survive cold winds. People visit mountains for hiking and to enjoy the beautiful natural views.

（二）Oceans and Beaches
Oceans cover most of Earth's surface and are part of the natural world. They are home to thousands of creatures, from tiny fish to large whales. Beaches are areas where ocean water meets land, often covered with sand or stones. At low tide, parts of the beach that are underwater at high tide become visible. Sea turtles lay their eggs on beaches, and crabs scuttle across the sand. Ocean waves are caused by wind, and they shape the beaches over time.

三、閱讀填空（根據內容及首字母提示填空）
Deserts of the World
Deserts are dry places in the natural world with very little rain. Some deserts are hot, like the Sahara, while others are cold, such as the Gobi. Cacti are common d 1 plants—they store water in their stems to s 2. Animals like camels have special adaptations, too. Camels can go for days without drinking because they store water in their b 3 . At night, deserts get much cooler than during the day. Even t 4 deserts seem harsh, they are an important part of the natural w 5 .

四、根據短文回答問題.
（一）Grasslands and Savannas
Grasslands are large areas covered mostly with grass, with few trees. They are part of the natural world and are found on every continent except Antarctica. Savannas are a type of grassland with more trees, found in Africa and South America. Many animals live in grasslands, including zebras, lions, and antelopes. Grasslands get more rain than deserts but less than forests. Fires are common in grasslands and help new grass grow. People use some grasslands for farming and grazing animals.
What are grasslands covered mostly with
On which continent are there no grasslands
What is a savanna
Name one animal that lives in grasslands.
How do fires help grasslands
（二）Weather in the Natural World
Weather is part of the natural world and includes rain, wind, sun, and snow. Rain helps plants grow and fills rivers and lakes. Wind is moving air that can spread seeds and cool things down. Sunlight gives energy to plants, which use it to make food—a process called photosynthesis. Snow covers the ground in cold places, keeping some plants and animals warm. All types of weather are important for the balance of the natural world. Changes in weather patterns can affect plants, animals, and people.
What does rain help plants do
What is wind
What do plants use sunlight for
What does snow do for some plants and animals in cold places
Why are all types of weather important
