Will you please tell me h
13、ow 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 weficaddto it, then we get its adjective.S4: “ achieve ” is a verb. If wemen
14、tadd to it, weget 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第4页共11页the meaning. For example, in the word unflatter ing, the root is simply flatter, while the
15、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.(ShowWord Formation on the powerpoint.)Step IIGrammarAsk students to observe the given words carefully and find out h
16、ow 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
17、 the following words and tell how they are formed. (Show the following words on the PowerPoint.)?affixinfix? prefix? suffixTeacher 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 set
18、tle 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第5页共11页?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 understan
19、dable, 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 somethinginside (a word).prefix - to attach something at the beginning o f (a word)What about af and suf?Thats a bit more diffi
20、cult 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
21、 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 somethin
22、gto (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 wordThere 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
23、 good for then?第6页共11页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
24、 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 meani
25、ngs of the Latin roots, look up the words in a good dictionary): (Show the following on the PowerPoint.)ab(away) abstain, absent, absolvead(to) adverb, advertisement, advance, adjoinin /il-/im-/ir-(not) incapable, indecisive, intolerable , illegal, impossible, irrugularinter(between, among) internat

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.

When you comeacross a new word, you can easily guess the meaning. Ok ,let s come to Exercise2.Deal with the rest of exercises in the same wa

Would you like to try some difficult ones?Now look at the following exercises. You are given 8 minutes.
32、 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
33、 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 WildeIn the centre of the room, clamped to
