四年级英语植物和自然世界课件
四年级英语植物和自然世界课件Section 1: Introduction to PlantsIn this section, we will explore the fascinating world of plants. We will learn about the importance of plants in our daily lives, their different parts, and how they grow.1.1 Importance of PlantsPlants play a vital role in our lives. They provide us with food, oxygen, and materials for clothing and shelter. Without plants, life on Earth would not be possible. We rely on them for our survival and the well-being of our planet.1.2 Parts of a PlantPlants have different parts that serve specific functions. The main parts of a plant are the roots, stem, leaves, flowers, and fruits/seeds. Each part plays a crucial role in the plant's growth and reproduction.1.3 How Plants GrowPlants start their life from seeds. When a seed is planted in the soil and provided with water and sunlight, it begins to germinate. The roots grow downwards, anchoring the plant and absorbing water and nutrients from the soil. The stem grows upwards, carrying water and nutrients to the leaves. The leaves use sunlight to produce food through a process called photosynthesis.Section 2: Types of PlantsIn this section, we will explore different types of plants found in our natural world. We will discover the characteristics and unique features of each type.2.1 Flowering PlantsFlowering plants, also known as angiosperms, are the most dominant type of plant on Earth. They produce flowers, which contain ovaries that develop into fruits and seeds. These plants include familiar examples such as roses, daisies, and sunflowers.2.2 Non-Flowering PlantsNon-flowering plants, or gymnosperms, do not produce flowers. Instead, they reproduce through cones or seeds. Examples of non-flowering plants include pine trees, spruces, and cycads.2.3 Ferns and MossesFerns and mosses are primitive plants that reproduce through spores. They do not have true roots, stems, or leaves like flowering plants. Instead, they have rhizomes and simple leaf-like structures. These plants are commonly found in moist environments such as forests and swamps.Section 3: Interactions in the Natural WorldIn this section, we will explore how plants interact with other living organisms in their environment. We will learn about pollination, seed dispersal, and the importance of maintaining natural habitats.3.1 PollinationPollination is the process of transferring pollen from the male parts of a flower to the female parts, leading to fertilization and the production of seeds. This crucial process is often done by insects, birds, or the wind. It ensures the survival and diversity of plant species.3.2 Seed DispersalSeed dispersal is the movement of seeds away from the parent plant to new locations. It helps plants colonize new areas and avoid competition with parent plants. Some common methods of seed dispersal include wind, water, animals, and explosive mechanisms.3.3 Importance of Natural HabitatsNatural habitats, such as forests, meadows, and wetlands, provide a suitable environment for plants to grow and thrive. They also support a diverse range of animal species. It is essential to protect and preserve these habitats to maintain the balance of nature and conserve biodiversity.Section 4: Human Impact on Plants and the EnvironmentIn this section, we will discuss the impact of human activities on plants and the environment. We will learn about deforestation, pollution, and the importance of conservation.4.1 DeforestationDeforestation refers to the clearing or destruction of forests for agricultural, industrial, or urban purposes. It has a significant impact on plant life, leading to habitat loss, soil erosion, and climate change. Efforts should be made to promote sustainable forestry practices and reforestation.4.2 Pollution and PlantsPollution, such as air and water pollution, negatively affects plant growth and development. Toxic pollutants released into the environment can harm plants, disrupt their reproductive systems, and reduce biodiversity. It is crucial to minimize pollution and promote eco-friendly practices.4.3 ConservationConservation plays a vital role in protecting plant species and the environment. Conservation efforts involve the preservation of natural habitats, the reintroduction of endangered plants, and the promotion of sustainable practices. By conserving plants, we ensure a healthier planet for future generations.ConclusionIn conclusion, plants are not only essential for our survival but also contribute to the beauty and harmony of our natural world. Understanding the different types of plants and their interactions with the environment is crucial for the well-being of both humans and the planet. Let us appreciate and protect these remarkable organisms that make life possible.。

根據日本科學家的研究發現,香蕉中具有抗癌作用的物質 。 而且,香蕉愈成熟其抗癌效果愈高。日本東京大學教授山崎正利利用動
物試驗,比較了香蕉、葡萄、蘋果、西瓜、菠蘿、梨子、柿子等多種水 果的免疫活性,結果證實其中以香蕉的效果最好,能夠增加白血球,改 善免疫系統的功能,還會產生攻擊異常細胞的物質 。 山崎教授的試驗也發現, 香蕉愈成熟即表皮上黑斑愈多,它的免疫活性 也就愈高。所以從現在開始要吃熟一點的香蕉唷! 香蕉不會使白血球盲 目增長只有在數量少的時候才會大幅度增加。 因此,專家們研究認為, 香蕉具有的免疫激活作用比較溫和 , 在人體狀態健康時並不會使免疫力 異常升高 . 但對病人、老人和抵抗力差的體弱者則很有效果。 因此,在日常生活中,我們不妨每天吃1~2根香蕉,透過提升身體的 抗病能力來預防感染,特別是預防感冒和流感等病毒的侵襲。山崎 教授 指出,在黃色表皮上出現黑色斑點的香蕉,其增加白血球的能力......... 要比表皮發青綠的香蕉強8倍

第6课(下):The Difference between Plants and Animals.doc
The Difference between Plants and Animals动物与植物之间的差别If you were asked,"What is the difference between a plant and an animal?"what answer do you think you would give?Your first thought might be that a plant has leaves and roots and flowers,which an animal has not.Yet that would not be correct;for there are many plants which have neither roots nor leaves nor flowers,while there are some animals which seem to have all three.如果要问你"动物与植物之间的差别是什么?"你想你会给一个什么样的答案呢?你可能首先想到的是植物有叶有根有花,而动物却没有。
可是这个答案并不正确,因为有很多植物既没根,也没有叶,更不开花,而有些动物却令人觉得根叶花三者俱备。
Look up into the sky,and then down at the earth beneath your feet.It is easy enough,you think,to tell which is earth and which is sky;but if you live in the wide,open country,or near the sea,you will often find when you look far away to the place where sky and earth seem to meet, that this is a matter of some difficulty.You see only the thin blue haze,like smoke,which is the dividing line between the heavens and the earth.But just where the one ends and the other begins, you cannot tell.抬头看看天空,然后再低头看看你脚下的大地。
