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。
植物学所有的动物都要依靠绿色植物的光合作用能力把日光能转化为化学能,释放出氧气来维持其生活。
植物是人类衣、食、用、住、行原料的直接或间接来源,是维持生物圈生态平衡的重要环节。
早期人类就能分辨出他们所接触到的植物,并给以命名。
随科学的发展,人们开始把对植物的知识系统化,并且记录下来成为植物学。
以后,进一步注意到它们的结构、化学组成、各部分的功能和繁殖方式。
而且自从人类懂得了栽培植物,研究内容更包括了其营养生长和繁殖,以及选育良种和对病虫害的处理。
20世纪植物学研究一方面走向微观,试求把植物的各种活动,物质、能量、信息的转化还原到细胞水平、分子水平、甚至电子水平,并创造了“细胞工程”、“基因工程”等方法以求迅速繁殖和创建植物新品种。
另一方面特别是70年代以来,又趋向宏观,研究“环境保护”、“生态工程”等课题,甚至扩大到地球生物圈的组成及其调控的研究等。
所以今天的植物学已发展为包括众多分支的知识体系。
70年代以来又常称之为植物生物学。
植物学发展简史至少在旧石器时代,人类在采集植物块根和果实种子供食用的时候就认识了某些植物。
希腊、埃及、巴比伦、中国、印度等文明古国对植物知识都有记述。
如中国《诗经》就已经讲究“多识于鸟兽草木之名”。
古希腊亚里士多德的学生提奥夫拉斯图被视为植物学的创始人。
他在公元前300年写的《植物历史》或称《植物调查》一书,在哲学原理基础上将植物分类,描绘其各部分、习性和用途。
罗马的老普林尼则把当时所有的植物学知识写在37册的《博物志》书中,开以后黑暗中世纪“百科全书学派”的先河,但谬误很多。
后陆续出现许多有关植物方面的著述。
如公元1世纪希腊医生迪奥斯科里德斯在其著作《药物论》中记述了600种植物及其医药用途的引证,成为以后描述药用植物的基础。
15~16世纪本草著作中最有价值的是日耳曼的布龙费尔斯,意大利的马蒂奥利、英国的特纳等的著作。
此时期约与中国明代中叶以后李时珍完成《本草纲日》同时。

Looking and talkingNow go to page 36. Look at the photos and listening to me talking to you about the living stones plant, Refflesia and pitcher plants.Pitcher plants (or pitfall traps) are carnivorous plants whose prey-trapping mechanism features a deep cavity filled with liquid. Insects such as flies are attracted to this cavity, often by visual lures such as anthocyanin pigments, and nectar bribes. The sides pf the pitcher are slippery and they are also grooved in such a way so as to ensure that the insects cannot climb out. The liquid contained within the pitcher traps, drowns, and gradually dissolves the body of the insect. This may occur by bacterial action, or be due to enzymes secreted by the plant itself. Furthermore, some pitcher plants contain mutualistic insect larvae, which feed on trapped prey, and whose excreta the plant absorbs. Whatever the mechanism of digestion, the prey items are converted into a 'soup' of amino acids, peptides, phosphate, ammonium and urea, from which the plant obtains its mineral nutrition(particularly nitrogen and phosphorus). Like all carnivorous plants, they occur in locations where the soil is too poor in minerals and/or too acidic for most plants to be able to grow.Rafflesia is a genus of parasitic flowers. It contains 18 species(including four inpletely known species as recognized by Meijer1997), all found in South-East Asia, on the Malay Peninsula,Borneo, Sumatra and Kalimantan, and the Philippines. The flowers have no leaves and hardly any stem, just a huge speckled five-petaled flower with a diameter up to one metre, and weighing up to 10 kg. Even the smallest species, R. manillana, has 20 cm diameter flowers. The flowers smell like rotting meat, hence its local names which translate to "corpse flower" or "meat flower". It is parasitic on a vine, spreading its roots inside the vine. The fruit is eaten by tree shrews. Rafflesia is a official state flower of Sabah in Malaysia.The species Rafflesia arnoldii is the world's largest single flower. It was discovered in the Indonesian rain forest by Sir Thomas Stamford Raffles and Dr. Joseph Arnold in 1818.The world's largest inflorescence is borne by the Talipot palm (Corypha umbraculifera). The largest unbranched inflorescence is the Titan Arum (Amorphophallus titanum) from the family Araceae. Now you are going to listen to a talk by Mark, Gordon and Andrea telling about these three unusual plants and plete the two charts on page 36.III.Reading for formsRead the text FLOWERS AND THEIR ANIMAL POLLINATORS on page 38 to: cut/ the sentence into thought groups, blacken the predicative, darken the connectives and underline all the useful expressions.IV. Copying expressions and making sentencesV. Investigating the importance of plantsPROCEDURE:Do you know why plants are important?You are going to investigate the importance of plants and produce a report in pairs.You may review the information provided in the "Background" section on page 31 first.Then read the text on page 32 second.After school you may use the Internet to get more necessary information. In some of the search engines like .. and .google. go over some of the key words that might help you to search more successfully.Words like: paper products, agriculture, fabrics, medicine, and food may produce a long list of sites you can investigate.。

Unit 4, Book 9
语法复习----直接宾语和间接宾语
[重点难点]:跟双宾语的动词的把握使用
[知识梳理]:
双宾语的复习请考虑以下几点
㈠. 直接宾语的位置
① 为了强调,宾语可置于句首。
What dull, old—fashioned leather shoes he’s wearing!
Talent, Mike has; patience, he has not.
② 为了衔接,宾语可以前置。
His carelessness had led him into great error. That error he determined to correct. Jack fried two small pieces of fish. One he fed to his cat, the other he ate himself ③ 为了插入,宾语可以前置
He found for the first time the necessity of using this book.
T hey s aw playing in the garden a group of children aged from six to twelve.
④ 短语动词后的宾语有两种位置
He tried out the machine./ He tried the machine out.
I’ll put on the radio in a minute./ I’ll put the radio on in a minute.
如果名词词组较长,一般采用第一种位置。
如
She tried on half a dozen parts of shoes before she found a suitable one.
若宾语是代词,则只能采用第二种形式。
The bed is too strong, and you can’t break it up.
㈡.带双宾语的动词。
有些动词可以有两个宾语,直接宾语表示作为动作对象的人或物,间接宾语表示动作的受益者或动作的结果。
① 间接宾语一般在动词之后,直接宾语之前。
Dr Robey handed David a piece of string.
She brought me a boiled egg and toast.
Dad gave me a car as my birthday present.
A man promised him a job the other day.
② 间接宾语还可置于直接宾语后的介词短语中。
He handed his room key to the receptionist.
Ralph passed a message to Jack.
这种结构更用于下列情况。
ⅰ突出间接宾语时,例如间接宾语比直接宾语长得多时
He ha s taught English to all the youth of Sri Lanka and India.
The magazine offered $100 to any reader who could tell what Bat had said.
ⅱ直接宾语为it或them等代词时
It was the only pound he had and he gave it to the little boy.
Woodward finished some pages of the article and passed them to the editor.
ⅲ 表示动作对谁做,间接宾语之前就用介词to 例
Mr Schell wrote a letter the other day to the New York Times.
I have lent my apartment to a friend for the weekend
③ 下列动词可带由to引出的间接宾语
award bring feed forward give hand leave lend mail offer owe
pass pay post read rent repay sell send serve show sing take teach tell write 等。
④表示动作为谁做,间接宾语前要用介词for
He left a note for her on the table.
Jack poured more champagne for three of them.
Mother made a new dress for my sister.
We have saved some apples for the beggars.
下列动词可带由for引出的间接宾语
bo ok bring build buy cook cut design fetch find fix get
guarantee ke ep leave make mix order paint pick play pour prepare sing take write等。
⑤ 在上述两类词中,均有动词 bring, leave, sing, take, write.这是因为这些动词依据其表达的意义,在间接宾语前用to或for
Karen wrote a letter for her boyfriend.
Karen wrote a letter to her boyfriend.
⑥ 有少数动词的间接宾语位于直接宾语之前时,要根据动词与介词的固定搭配来选用介词。
不同于上述用to或for的情况。
He played me a trick.
He played a trick on me.(比较:Won’t you play some folk songs for us?)
㈢有些动词表示对某人“说话”,一般只能用to+ somebody 形式。
这类动词常见的有:announce, describe, dictate, disclose, explain, express, introduce, mention, point out, repeat, report, say, shout, suggest, whisper等。
如:
Our teacher explains to us the difficult points in the unit.
We disclosed to them the secret of our invention.
They expressed to their teacher their conviction that the experiment was true. The guide is describing the scenic spots to the tourist
