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.。

Unit 4 Exploring plants-readingPart One: Teaching DesignPeriod 1: A sample lesson plan for reading(PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES)AimsTo help students develop their reading abilityTo help students learn exploring plantsProcedures■Warming up by defining plantsPlants are a major group of living things (about300,000 species), including familiar organismssuch as trees, flowers, herbs, and ferns.Aristotle divided all living things betweenplants, which generally do not move or havesensory organs, and animals. In Linnaeus' system,these became the Kingdoms Vegetabilia (laterPlantae) and Animalia. Since then, it has becomeclear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts. Indeed, any attempt to match "plant" with a single taxon is doomed to fail, because plant is a vaguely defined concept unrelated to the presumed phylogenic concepts on which modern taxonomy is based.Warming up by talking about different gardensGardens vary in forms and functions. How many can you see in your area?■Warming up by discussing gardeningGardening is the activity of growing and maintaining the garden. 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. Landscape architecture is a related professional activity with landscape architects tending to specialise in design for public and corporate clients.I. Pre-readingWhat is a garden?A 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 garden. 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. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobbyrather than produce for sale); this distinction is not always clear-cut, however. The gardening article discusses the differences and similarities between gardens and farms in greater detail. Gardening is the activity of growing and maintaining the garden. 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. Landscape architecture is a related professional activity with landscape architects tending to specialise in design for public and corporate clients.II. 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.III. 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.IV. Reading and transformingRead the text again to complete the chart to fill in the topic sentence of each paragraph.V. Closing down by learning about prehistoric plantsPrehistoric plants are various groups of plants that lived before recorded history (before about 3500 BC).Plants have remained remarkedly unchanged thoughout earth's geological time scale. Early ferns had developed by the Mississippian, conifers by the Pennsylvanian. Some plants of prehistory are the same ones around today and are thus living fossils, such as Ginkgo biloba and Sciadopitys verticillata.Complete the summary of the text with one word in each blank.It was not ___1__ the eighteenth and nineteenth centuries __2___the exploration of the botanical world began __3___ a large scale．An important group of collectors ___4___ French Catholic missionaries ____5__，by the middle of the 18th century，__6____ beginning to set themselves up in China．__7____ plants alive during long land or sea voyages ___8___ an enormous challenge.__9____ numbers of seeds failed to grow after long sea __10____ or trips across land ___11___ Asia and Europe.
