Target language目标语言: Learn the Grammar- Word formation (I)2. Ability goals能力目标: Study the ways of forming a word and enlarge students vocabulary.3. Learning ability goals学能目标：Enable students to use context clues and what they know about word parts to guess the meaning of new words.Teaching important points教学重点The ways of forming a word.Teaching difficult points 教学难点How to guess the meaning of a new word.Teaching methods教学方法Explaining and practisingTeaching aids教具准备1. a projector 2. a computerTeaching procedures & ways教学过程与方式Step I Lead inT: Good morning afternoon, class!Ss: Good morning afternoon,Mr/MsT: In this class, we are going to start Unit 11 Scientific achievements .Now pay attention to the two words. Will you please tell me how the two words are formed?S1“Scientific”is the adjective form of” Science”.S2:“Achievement “ is the noun form of “achieve”.T: Observe them carefully; can you explain how they are formed?S3:” Science” is a noun, if we add fic to it, then we get its adjective.S4: “achieve” is a verb. If we add ment to it, we get its noun.T: Excellent ! That is how the two words are formed. The basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. For example, in the word unflattering, the root is simply flatter, while the prefix un- makes the word negative, and the suffix -ing changes it from a verb into an adjective (specifically, a participle).This is the grammar we are going to learn in this class.(Show Word Formation on the powerpoint.)Step II GrammarAsk students to observe the given words carefully and find out how words are formed. (Show the following words on the PowerPoint.) affix infix prefix suffix Teacher explains the following.ab (away) abstain, absent, absolve ad (to) adverb, advertisement, advance, adjoin in /il-/im-/ir- (not) incapable, indecisive, intolerable , illegal, impossible, irrugularinter (between, among) international, interaction interdependent, interprovincial pre (before) prerecorded, preface prefer post (after) postpone, postscript, postwar sub (under, not quite) subsoil, subscription, suspect ,subway, subnormaltrans (across, to a changed state) transfer, transit, translate, transport ,transformStep III PracticeT: Are you ready for some exercises? Open your books and look at Page6. Lets do the exercises. Lets do Exercise 1 first .How are these words formed? (Or show the following words on the PowerPoint).international= inter-+national telephone= tele-+phone mankind=man+kind broadband= broad+bandextremely=extreme+-ly manned= man+ -edhi-tech= high+technology email= electronic mailIT= information technology CSA= Chinese Space AgencyS1:I think international and telephone are formed in the same way. We add prefix inter- to national and tele- to phone.T: Good! What about the others?S2: Mankind and broadband are formed in the same way. Each is made up of two words. S3:Extremely and manned are formed by adding a suffix.S4:Hi-tech is the shortened form of high technology and e-mail is the shortened form of electronic mail.S5: IT stands for information technology. We use the first letters of the two words to form a new one .We use the first letters of Chinese Space Agency to form the word CSA.T；Well done .So we know that words are formed in these ways. When you come across a new word, you can easily guess the meaning. Ok ,lets come to Exercise2.Deal with the rest of exercises in the same way.Step IV WorkbookStep V WORD FORMATION EXERCISES(If there isnt enough time, please print it out and give the handouts to students as homework)T: Im very glad youve done the exercises quite well.

If you have any difficulty, you may work with your partner or refer to a dictionary. ( Show the following exercises on the powerpoint.)Use the word at the end of each gap to form a new word with which to fill the gap. While doing this exercise, look for clues which tell you what kind of word is missing (adjective, noun, verb, adverb).
