Period 1 A sample lesson plan for reading (PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES) Introduction

In this period, after warming up, students will first be introduced to gardening. Then they will be helped to read an exposition about plants exploration. 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 1.To help students learn to express emotions (wonder, disgust) 2.To help students learn to read an exposition about plants exploration 3.To help students better understand “plants”

4.To help students learn to use some important words and expressions

5.To help students identify examples of the direct object and indirect object in the text

Date back to, appear to, give out In 1833, Ward shipped two cases of British plants to Sydney, Australia.

Collecting “exotic” plants，as they are called，dates back to the earliest times．

However，it was not until the eighteenth and nineteenth centuries that the exploration of the botanical world began on a large scale．

Large numbers of seeds failed to grow after long sea voyages or trips across land between Asia and Europe.

Ward shipped two cases of British plants to Sydney，Australia．

He made several trips to China between 1843 and 1859.

Not only did Fortune introduce over 120 species of plants to Western gardens but he also shipped 20,000 tea plants from Shanghai to India，where a successful tea industry was established．

Procedures 1Warming up

⑴Warming up by defining plants

We 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 gardens

⑶Warming up by discussing plant exploration Plant 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 this continent.

2. Pre-reading by getting to know what a garden is 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.

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.

3. Reading for forms

Read 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 sentences You 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. Expressions from: PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES date back to the earliest times, bring back…from distant lands, gather plants，it was not until…that…, on a large scale, take the opportunity of…, go on botanical expeditions, face many dangers, set one selves up in…, vast quantities of…, keep… alive, be transported on long journeys, make a return trip, make trips to…, shave one's head in the Chinese style, experience many adventures, pirates on the Yangtze River, value the study of the natural sciences, result in, appeal to sb. 5. Reading and transforming Read the text again to complete the chart to fill in the topic sentence of each paragraph. PLANT EXPLORATION IN THE 18TH AND 19TH CENTURIES

Paragraph1

Collecting “exotic

”plants，as they are called，dates back to

the earliest times．

Paragraph2 However，it was not until the eighteenth and nineteenth centuries that the exploration of the botanical world began on a large scale．

Paragraph3 An important group of collectors were French Catholic missionaries who，by the middle of the 18th century，were beginning to set themselves up in China．

Paragraph4 Sir Joseph Banks was a very famous British plant collector，who accompanied James Cook on his first voyage from England to Oceania．

Paragraph5

Keeping plants alive during long land or sea voyages was an enormous challenge. Paragraph6 The world of plant exploration was completely changed with Dr Nathaniel Ward’s invention of a tightly sealed portable glass container．

Paragraph7 A British man called Robert Fortune was one of the earliest plant collectors to use Wardian cases．

Paragraph8 The second half of the nineteenth century was a very important period of plant exploration．

Paragraph9 Although the missionaries collected large numbers of specimens，there was not enough material for growing particular species in Western gardens．
