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 LakesRivers 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.

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 答案一、阅读判断(一)1.T 2.F 3.T 4.F 5.T(二)1.T 2.T 3.F 4.F 5.T二、阅读选择(一)1.B 2.C 3.B 4.B 5.C(二)1.B 2.C 3.A 4.B 5.C三、阅读填空Desert 2. survive 3.bodies 4. though 5.world四、根据短文回答问题(一)Grass.Antarctica.A type of grassland with more trees.Zebras, lions, or antelopes.(任答一项即可)They help new grass grow.(二)Grow.Moving air.To make food (through photosynthesis).Keep them warm.For the balance of the natural world.21世纪教育网 www.21cnjy.com 精品试卷·第 2 页 (共 2 页)21世纪教育网(www.21cnjy.com) 展开更多...... 收起↑ 资源预览
