2019-2020年高中英語 Unit1 Word power教案 譯林牛津版必修4 We’ll learn in this section some mon suffixes that can be added to nouns or verbs to create adjectives. And also some vocabulary related to sales and marketing. Step 1: Brainstorming 1. Please think about the following questions: How are the following words formed? health (noun) healthy(adjective) interest (verb) interesting (adjective) An English word can have several derivatives. And please pay attention to the fact that many English words share the same root word, even though they have different meanings or parts of speech. Now here’s more example for you to better understand word formation. breath (n.) breathe (v.) breathless (adj.) act (v.) action (n.) actor (n.) actress (n.) activity (n.) possible (adj.) impossible (adj.) possibility (n.) possibly (adv.) friend (n.), friendly (adj.), friendless (adj.), friendship (n.), unfriendly (adj.) As you can see, many words are derived by adding suffixes or prefixes to the root words. Often you may e across unfamiliar words while reading, try to use knowledge of word formation to guess their meanings. Will you? And can you give more examples about word formation? 2. Shall we have a petition to see who can give more examples or create more words by adding suffixes or prefixes to the root words? 3. As we know, sometimes an English word can be made up of three parts: a prefix, a stem and a suffix. A stem is the main part of a word. A prefix is a group of letters added to the beginning of a word. A suffix is a group of letters placed at the end of a word. Both prefixes and suffixes modify the meaning of a word or change it into a different word group. The following is a table of mon prefixes: Prefix Meaning Examples (adjectives) un- Not unfair, unnecessary, unimportant, unhappy in- Not incorrect, invisible, incurable, inaccurate dis- showing opposite disable, dishonest, disagree, disappear, discover re- do again rewrite, redo, rebuild, react, retell, recreate mis- badly or wrongly misunderstand, misdirect, mistake, misuse Step 2: Learning about Word formation 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). English itself does not use prefixes as heavily as it once did, but many English words e from Latin, which uses prefixes and suffixes (you can use the word affix to refer either to a prefix or a suffix) quite extensively. For example, the words "prefix," "suffix," and "affix" themselves are all formed from "fix" by the use of prefixes: "ad" (to) + "fix" (attached) = "affix" "pre" (before) + "fix" = "prefix" "sub" (under) + "fix" = "suffix" Note that both the "-d" of "ad" and the "-b" of "sub" change the last letter. Here are some of the most mon Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary): ab (away) abrupt, absent, absolve ad (to) adverb, advertisement, afflict in (not) incapable, indecisive, intolerable inter (between, among) intercept, interdependent, interprovincial intra (within) intramural, intrapersonal, intraprovincial pre (before) prefabricate, preface prefer post (after) postpone, postscript, postwar sub (under) submarine, subscription, suspect trans (across) transfer, transit, translate Step 3: Ready used materials for Word formation Affixes Morphemes added to free forms to make other free forms are called affixes. There are three principle kinds of affixes: 1. prefixes (at beginning) — "un-" in "unable" 2. suffixes (at end) — "-ed" in "walked" 3. circumfixes (at both ends) — "en--en" in "enlighten" (These always seem to consist of otherwise attested independent prefixes and suffixes.) A Rule for Forming some English Words Consider the following pairs of English words: Adjective Verb dark darken black blacken red redden steep steepen What generalization (rule) can we make? Form: "en" bination: At the end of Adjectives (suffix) to make Verbs Meaning: "to make (more) Adjective" We can draw a diagram to show the internal structure of one of the words: Verb / \ Adjective -en | black Meaning: "to make (more) black" Likewise we can draw a partial structure (tree diagram) which shows the three properties of rule of bination for the affix: Verb / \ Adjective -en Meaning: "to make (more) Adjective" Another Rule for Forming some English Words Consider the following pairs of English words: Verb Noun sing singer dance dancer write writer pute puter What generalization (rule) can we make? Add "-er" to the end of Verbs to make Nouns with the meaning "someone (or sth.) that Verbs" Noun / \ Verb -er Meaning: "someone (or something) that Verbs" Rules that dont change category Some affixes create the same kinds of words that they attach to, such as making nouns out of other nouns: Noun / \ Noun -ian | Boston Meaning: "someone from Boston" Zero Morphemes Some affixes consist of no sounds at all. Zero morphemes DO exist, and well see why, and illustrate another concept, allomorphy at the same time. Consider the following words: Adjective Verb yellow yellow brown brown green green purple purple The relation between "yellow" (adjective) and "yellow" (verb) is exactly the same as that between "white" and "whiten", which we just considered. But the form of "yellow" doesnt change. So we say that we added a zero suffix: Verb / \ Adjective - | yellow Meaning: "to make (more) yellow" Zero morphemes are obviously hard to spot because you cant hear them! In these cases you have to notice what ISNT there. (Sherlock Holmes solves one of his cases by noticing that a dog DIDNT bark. This was important because there was a situation where any dog would have barked. This is the kind of thinking you have to do to find zero morphemes.) Allomorphy But now we have two ways to make Adjectives into Verbs meaning "to make (more) Adjective": "-en" ("black-en") and "-" ("yellow-") How do we know which rule to use? That is, why not "yellow-en"? One possible (but uninteresting) answer is that we just have to memorize which affix to use for each stem. That is, we just memorize that "black" takes "-en" and "yellow" takes "-". But we would like a better explanation. As with the phonology problems, the best place to look is "near" where the affix attaches. Since "-en" is a suffix, lets look at the end of the stems. What we find is that we can divide the Adjectives into two classes based on what the last SOUND (NOT letter) of the stem is: Use "-en" if the last sound is: [p] "deep-en" [f] "stiff-en" [v] "live-en" [t] "white-en" [d] "redd-en" [s] "less-en" [?] "fresh-en" [k] "dark-en" Use "-" if the last sound is: [e] "gray-" ("His hair grayed (gray--ed) before he was twenty.") [n] "brown-" [m] "dim-" [l] "purple-" [r] "clear-" We can use the same type of diagrams, and indicate the conditions: Verb / \ Adjective -en if Adjective ends in an obstruent (oral stop or fricative) - if Adjective ends in a sonorant (nasals, approximants, vowels) Meaning: "to make (more) Adjective" When we did phonology problems, we had a notion of "default" or "elsewhere". The same concept can arise in morphology, although in this case the choice is made difficult by the clean cut between obstruents and sonorants. It is true, however, that there are exceptions to this rule with certain unusual adjectives: Verb / \ Adjective -en if Adjective ends in an obstruent (oral stop or fricative) - Elsewhere Meaning: "to make (more) Adjective" Another example of allomorphy in English is the choice of the negative prefix "il-/ir-/im-/in-". The rules are: Use "il-" when the stem begins with "l": "il-legal" Use "ir-" when the stem begins with "r": "ir-responsible" Use "im-" when the stem begins with "m, b, p": "im-mobile" "im-balanced", "im-possible" Otherwise (elsewhere) use "in-": "in-active", etc. In a diagram: Adjective / \ when Adjective begins with l: il- Adjective when Adjective begins with r: ir- when Adjective begins with a bilabial: im- Elsewhere: in- Meaning: "not Adjective" Notice here that there is a clear case that applies when the other (more specific) rules cannot. This is the DEFAULT or ELSEWHERE rule. The ELSEWHERE concept plays an important role in linguistics and we have already encountered it in phonology and we will encounter it again in this course. Finally, some allomorphy is simply exceptional. There are morphemes which are used with only a limited number of words, such as plural "-en" as in "ox-en", "child-(r)en". Furthermore, some words are so irregular that they have no internal analysis, for example "went" is the SUPPLETIVE form for what would otherwise be "go-ed". Children often use words like *"go-ed" ("went") or *"hold-ed" ("held"). These are called OVERGENERALIZATION errors because the children use a regular productive process on exceptional words. pounds The bination of two free forms is called a POUND. Noun / \ Adjective Noun | | black bird Meaning: a particular kind of bird In English the HEAD of a pound is usually the right-hand member (bird). The head supplies the category (Noun) and basic meaning (bird-ness) for the whole pound. pounds can be used with affixation to produce larger words: Noun / \ Verb -er / \ Verb Verb | | sleep walk Meaning: Someone who walks and sleeps at the same time Noun / \ Noun Noun | / \ window Verb -er | painter Meaning: Someone who paints windows Bound Roots Both "blackberry" and "blueberry" are kinds of BERRIES, and "black" and "blue" exist as free forms too. So these look like fine pounds. But what about "cranberry", "huckleberry", "strawberry"? Wed like to keep the "berry" part separate, but then what are "cran", "huckle" and "straw"? We call these cases BOUND ROOTS. Homophonous Morphemes Sometimes two morphemes have the same pronunciation (form) with different meanings. One example form English is the two morphemes "un-": Adjective / \ un- Adjective Meaning: "not Adjective", for example "unhappy" Verb / \ un- Verb Meaning: "do the reverse of Verb", for example "undo", "untie", "unlatch" This can lead to ambiguity in some words with "un-", such as "un-tie-able". There are two possible structures for "un-tie-able": Adjective / \ Verb -able / \ un- Verb | tie Meaning: able( un (tie) ) = "can be untied" Adjective / \ un- Adjective / \ Verb -able | tie Meaning: un( able (tie) ) = "cant be tied" The relative scope of "un-" and "-able" is different in these two cases, leading to a difference in meaning. The difference in meaning also correlates with whether "un-" is modifying a verb or an adjective. When a difference in meaning correlates with a difference in structure like this we call this STRUCTURAL AMBIGUITY. Structural ambiguity is a very important concept. We will see exactly the same thing when we analyze sentences. Other ways of Forming Words Back formations Where one "falsely" uses a rule. "peddler" refers to a person analyze "peddler" as "peddle" + "-er" Blends: "smoke" + "fog" = "smog"; "motor" + "hotel" = "motel" Words from Names: "jumbo", "sandwich" Truncation (Clipping): "gym(nasium)", "(tele)phone" Acronyms: "AIDS" = "Acquired Immune Deficiency Syndrome" Other references: 句式合成詞 整個(gè)句子當(dāng)作一個(gè)詞用,有的已經(jīng)固定下來,例如pick-me-up(興奮劑),whats-his-name(某某人)。整個(gè)句子用作形容詞的現(xiàn)象比較普遍,把復(fù)雜的概念揉成單純的限制語使行文緊湊。A let-bygones-be-bygones manner(一種“過去的就算了吧”的態(tài)度) an if-you-would-only-be-guided-by-me expression(一種“要是你肯聽了我的話多好”的神氣) 否定前綴 (1)純粹表示否定的a-, an- 能構(gòu)成少數(shù)新詞。加在名詞、形容詞上,表示沒有“某種性質(zhì)“。如:amoral[=unmoral]不道德,asexual無性別的。a-在元音前變成an-如anonymous [onoma=name]匿名的 dis-加在名詞、形容詞、動(dòng)詞上,表示否定, 如:disadvantage(劣勢(shì)),disagreement(不和),disbelieve(不相信)。 (2)表示“錯(cuò)誤”的mis- 多作重讀,表示“wrongly,badly”??梢赃m當(dāng)構(gòu)造新詞: 大多用于動(dòng)詞:to misbehave(行為不當(dāng))misunderstand(誤解)。 用于作形容詞的分詞:misbelieving(信仰不當(dāng)),misleading(靠不?。? 用于動(dòng)名詞:misdealing(不正當(dāng)手段)。 偶而,mis-也表示純粹的否定詞義:to mistrust。 (3)表示“反對(duì)” anti- 表示“反對(duì),反面” , 如: anti-social(反社會(huì)的) antiseptic(防腐劑) anti-militarist(反軍國主義者)。 contra- 表示“反對(duì),相反” , 如: contradiction(矛盾) contrast(對(duì)比) contrary(相反的);counter- 表示“against” , 如: counteract(還手) counterattack(反攻)。 其他前綴 前綴大都表示空間,時(shí)間,邏輯上的關(guān)系,意思上有引申。 ab- apo- se- 這幾個(gè)前綴或多或少都有“away ,off”的含義。 ab- a- abs- 在p, m, v之前作a-,在c, t之前作abs-,不能構(gòu)造新詞,表示“away ,apart, absence”,例如:absent, avoid。 se- 表示“separation”(分離),例如:segregate(隔離),sedition(反叛)。 ante-,fore- pre-這幾個(gè)前綴都有“before”的意思。 ante- 表示在……前,例:ante-humous(死前),ante-room(前廳)。 fore- 表示時(shí)間,空間上的“在前面”,例forehead(前額),foregraound(前景),foretell(預(yù)言)。 pre- 表示事先,在前,例prehistory(史前),prepayment(預(yù)支)。 post- 表示時(shí)間空間上的在后,例:posterity(后代),post-war(戰(zhàn)后)。 pro- 表示“代替,利于,親于”,例pro-chancellor(代大學(xué)校長),pro-consul(代理領(lǐng)事)。 circum- peri- 這兩個(gè)前綴跟圓周有關(guān)。 circum- 表示圓周,如circumference, circumlocution, circumpolar。 peri- 表示“round”,如perimeter(周長),perisphere(勢(shì)力范圍)。 課后練習(xí) Many of us mistakenly believe that its wrong to think we have any good qualities. We may spend a lot of time blaming ourselves for our negative qualities, thinking that self criticism is the key to improving our performance. However, a constant focus on our supposed shortings can stop our efforts to make friends with other people. How can we believe that others could like us if we believe our inner being is flawed(有缺陷)? If someone seems to dislike you, the reason for that dislike might have little or nothing to do with you. The person who doesnt like you might be fearful, or shallow, or busy or shy. Perhaps you and that person are simply a mismatch for each other at this particular time. Dont take yourself out of the game by deciding that your flaws are bigger than your good qualities. In fact, some of the very qualities you consider to be flaws may be irresistible to someone else. For all the factors that might cause one person to reject you, there are at least as many factors that will work in your favor with someone else. You might be thirty pounds over your ideal weight, but you may have a wonderful laugh and a real enthusiasm for life. There are many people who don’t mind your extra pounds. You may drive a shabby car, but you might be a great dancer and a loyal friend. There are people out there looking for loyalty, or fun, or sweetness, or wisdom, and the package it es in is not important. If you are worried that you are not beautiful enough to attract friends, keep in mind that not everyone is looking for physical beauty in their friends. You can decide to feel inferior(自卑) because you dont have much money and you dont drive a nice car. You can believe that this is the reason that you dont have many friends in your life. On the other hand, if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes you as a person. The point is that you can focus on just about anything and believe its the reason you do not have friends and cannot make any. 36.
