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.T: How do learners improve their vocabulary? There are no super shortcuts to vocabulary, but there are various forms of support. Here is one example. Increasing your vocabulary is so important that you just cant forget about it. Dont bury your head in the sand. OK. Please look at the following words and tell how they are formed. (Show the following words on the PowerPoint.) affix infix prefix suffix Teacher explains the following.T: What do these words (nouns) have in common? Ss: All of them contain the root “fix”.T: Well, they do have a number of things in common. Lets settle for the most obvious, the fix at the end. So if we split them, this is what we get af + fix in + fix pre + fix suf + fix (These will be shown on the PowerPoint)T: What does fix mean?Ss: Fix means attach to, fasten, stick, glue.T: What about af , in , pre , suf ? in and pre are understandable, arent they ?in a room, in a sentence, in a word. pre means before like in pre-war, pre-school, premature. So what do infix and prefix actually mean? infix - to attach something inside (a word).prefix - to attach something at the beginning of (a word)What about af and suf?Thats a bit more difficult to explain. af is actually from the beginning the Latin word ad, and the meaning is the same as the English word add. Add 4 and 5 and you get 9.suf is the Latin word sub, like in submarine, subway, suburb. The meaning is under, after (outside).Why have the d in ad and the b in sub changed into f?The reason is really quite simple. adfix and subfix are difficult to pronounce. There is economy in everything! You simply leave out the d and the b, but in order to mark their existence the words are spelt with an extra f .So what do affix and suffix actually mean?Ss: affix - to attach something to (a word)suffix -to attach something at the end of (a word)T: We have now fixed the fixes, havent we? affix - something you add (stick) to a word There are three kinds of affixes:added inside the word - infixadded at the beginning of the word - prefixadded at the end of the word suffixSs: Whats this good for then?T: Well, there are thousands of words with prefixes and suffixes. The infixes are fewer and less useful to you. The English vocabulary basically consists of words of Latin and Germanic origin. There are prefixes in both groups.If you know the basic meaning of a prefix or a suffix you can often guess the meaning of an English word. There are a limited number of Latin prefixes and suffixes. If you learn the meaning of them, and learn to recognize them in English words, you will increase your vocabulary much faster.Here are some of the most common Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary): (Show the following on the PowerPoint.)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. Would you like to try some difficult ones?Now look at the following exercises. You are given 8 minutes. Then we will check the answers together. 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). Make sure to take into consideration forms using various prefixes and suffixes, as well as negative forms.EXERCISE # 1This text was taken from The Picture of Dorian Gray by Oscar Wilde窗体顶端In the centre of the room, clamped to an upright easel, stood the full-length portrait of a young man of _(ORDINARY) personal beauty, and in front of it, some little _(DISTANT) away, was sitting the artist himself, Basil Hallward, whose sudden _(APPEAR) some years ago caused, at the time, such public _ (EXCITE), and gave rise to so many strange conjectures. As the painter looked at the _ (GRACE) and comely form he had so _(SKILL) mirrored in his art, a smile of _ (PLEASE) passed across his face, and seemed about to linger there. But he _(SUDDEN) started up, and, closing his eyes, placed his fingers upon the lids, as though he sought to _(PRISON) within his brain some curious dream from which he feared he might _(WAKE).窗体底端EXERCISE # 2This text was taken from The Time Machine, by H(erbert) G(eorge) Wells窗体顶端It is simply this. That Space, as our _(MATHS) have it, is spoken of as having three dimensions, which one may call _(LONG), Breadth, and _(THICK), and is always definable by _(REFER) to three planes, each at right angles to the others. But some philosophical people have been asking why THREE dimensions _ (PARTICULAR) -why not another direction at right angles to the other three?-and have even tried to construct a Four-Dimension geomet
