Unit 4 Exploring plantsPart 1 Teaching Design第一部分教学设计Period 1 A sample lesson plan for reading(PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES)IntroductionIn this period, after warming up, students will first be introduced to gardening. Then they will be helped to read an exposition about plants exploratio n. While reading the form of the language is stressed.Three “Warming Up” designs are presented in this book for teachers’ reference. Computer and overhead projector may be used to aid the teaching and learning. Objectives■To help students learn to express emotions(wonder, disgust)■To help students learn to read an expositionabout plants exploration■To help students better understand“plants”■To help students learn to use some important words and expressions■To help students identify examples of the direct object and indirect object in the textFocusAidsMultimedia facilities, tape-recorder, photos, diagramsProcedures1Warming up⑴Warming up by defining plantsWe see plants every day. But what are they?Plants are a major group of living things (about 300,000 species), including familiar organisms such as trees, flowers, herbs, and ferns. Aristotle divided all living things between plants, which generally do not move or have sensory organs, and animals.⑵Warming up by talking about different gardensGardens vary in forms and functions. How many can you see in your area?⑶Warming up by discussing plant explorationPlant Exploration is the search for new, undiscovered plants. The principal objective of most plant exploration expeditions is to provide germplasm resources for existing breeding programs, biotechnology, and conservation. Insight must also be used to identify new species or those that have not been evaluated on this2. Pre-reading by getting to know what a garden isA garden is a planned space, usually outdoors, set aside for the display, cultivation, and enjoyment of plants and other forms of nature. The garden can incorporate both natural and man-made materials. The most common form is known as a residential garde n. Western gardens are almost universally based around plants. Zoos, which display wild animals in simulated natural habitats, were formerly called zoölogical gardens. Some traditional types of eastern gardens, such as Zen gardens, use plants sparsely or not at all.Gardening is the activity of growing and maintaining the garde n. This work is done by an amateur or professional gardener. A gardener might also work in a non-garden setting, such as a park, a roadside embankment, or other public space.3. Reading for formsRead the text PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES to: cut/ the sentence into thought groups, blacken the predicative, darken the connectives and underline all the useful expressions.4. Copying expressions and making sentencesYou are asked to copy all the useful expressions into your notebook after class as homework. You may make your own sentences with each of these expressions.5. Reading and transformingRead the text again to complete the chart to fill in the topic sentence of each6. Making a diagram of PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES and retelling it in your own words7. Closing down by taking a quiz。

Unit 4 Exploring plantsPart 2 Teaching Resources第二部分教学资源Section 1 Backgrounds f or Unit 4 Exploring plants1.Importance of PlantsPlants form the basic food staple for all life forms. They a re the major source of food and oxygen on earth, since no animal can supply these necessary components without p lants. Th e cattle we eat as beef, feed on grasses and the fish we eat, consume algae and are therefore dependen t on plants for well being. Other important uses of plants include, providing shelter for animals, providing materials for clothing (cotton fibers), paper products, medicines and other chemicals, producing coal from once living plant materi al, reducing wind speed and noise level s, and reducing soil erosion and water runoff.2. The life cycle of a plantThe life cycle of a plant varies depending on the individual species. There are, however, certain requirements for life that most plants need. The growth of a plant is dependent upon light, water, oxygen, car bo n dioxide, minerals in the soil, temperature and microbes in the soil. Light, water, and carbon dioxide are needed for photosynthesis which produces food for the plant. Oxygen is needed when it is dark, because the plant then needs oxygen to maintain itself.。
