Articles(冠词)的用法
Used with permission from the RPI Writing Center by John R. KohlIntroductionThe articles a, an, and the are difficult for many non-native speakers of English to learn to use properly. Some of the rules that govern article usage are very subtle; only years of experience with the language will enable you to understand and apply these rules. However, Table 3 will help you eliminate many errors in article usage from your writing.In order to use Table 3, however, you have to understand two concepts: countability and definiteness. These concepts are explained in detail below. The last part of this handout discusses article usage with proper nouns as well as the difference between a and an. At the very end of the handout is an exercise that you can do to test your understanding.CountabilityCountable nouns refer to people, places, or things that can be counted (one dollar/two dollars, one house, two houses). They [these countable nouns] can always be made plural--usually by adding -s or some other variation of the plural ending, e.g.student(s), countri(es), child(ren). A few words are the same in both the singular and plural forms (deer, sheep).Uncountable nouns often refer to food, beverages, substances, or abstractions (meat, tea, steel, information); some uncountable nouns (but not the abstract ones) can be made countable by adding a count frame in front of them (two gallons of milk, six blocks of ice, a bar of soap, a bunch of celery).Unfortunately, there is no clear-cut distinction between countable and uncountable nouns. Some nouns can be both countable and uncountable even without adding count frames. For example, as an uncountable noun, experience refers to abstract knowledge or skill that can be gained by observing or participating in events. As a singular or plural countable noun (experience/experiences), the word experience refers to a particular instance (or instances) of participation in events. Similarly, the uncountable noun glass is a substance made from silicates; a glass (singular) is something you drink from; and glasses (plural) are frames containing lenses that correct imperfect vision.There are other exceptions to the countable/uncountable distinction as well. Moreover, a noun that is countable in your native language may be uncountable in English, and vice-versa. For example, soapis countable in Spanish but uncountable in English. However, as long as you are aware of these differences they probably will not cause you much difficulty.LEARNING HINT #1: The best thing to do is to memorize some of the most frequently occurring uncountable nouns (shown in Table 1 below), and to look up other nouns in a dictionary if you are not sure whether they are countable or uncountable. If your dictionary does not indicate whether nouns are countable or uncountable, then you should consult another dictionary, such as The Oxford Advanced Learner's Dictionary.In the Oxford dictionary, nouns are countable unless they are designated by the letter [u]. If a noun can be either countable or uncountable (with different definitions, as in the examples given above), then the uncountable definitions are preceded by [u], and the countable definitions are preceded by [c], as in the following example:ad-ven-ture n. 1 [c] a strange or unusual happening (The explorer told the boys about his adventures in the Arctic). 2 [u] risk; danger (Robin Hood lived a life of adventure).Table 1: Some Common Uncountable English Nouns∙Food and Drink:bacon, beef, beer, bread, broccoli,butter, cabbage, candy, cauliflower, celery, cereal,cheese, chicken, chocolate, coffee, corn, cream,fish, flour, fruit, ice cream, lettuce, meat, milk, oil,pasta, rice, salt, spinach, sugar, tea, water, wine,yogurt∙Nonfood Substances: air, cement, coal, dirt,gasoline, gold, ice, leather, paper, petroleum,plastic, rain, rubber, silver, snow, soap, steel, wood,wool.∙Abstract nouns:advice, anger, beauty, confidence,courage, employment, fun, happiness, health,honesty, information, intelligence, knowledge, love,poverty, satisfaction, truth, wealth∙Others: biology (and other areas of study), clothing,equipment, furniture, homework, jewelry, luggage,lumber, machinery, mail, money, news, poetry,pollution, research, scenery, traffic, transportation,violence, weather, workDefinitenessA noun is definite if it refers to something specific that is known to both the writer/speaker and the reader/listener. (Note: You shouldmemorize this definition!) For example, if Jane needs to drive somewhere, she might ask her father, "May I use the car?" She uses the definite article the because both she and her father know which car Jane is referring to (the family car). But later Jane might say to her friend Bill, "I saw a funny-looking dog today." She uses the indefinite article a because she knows which dog she saw, but Bill doesn't.Table 2 below illustrates that there are four possible conditions involved in this decision, but only one results in a noun that is definite.Table 2: Matrix of Definiteness/Indefiniteness *In the following examples, definiteness is determined bywhether the Writer/Speaker and the Reader/Listener knowsspecifically what is being referred to:∙Definite: "Can I use the car?"Writer/Speaker: YESReader/Listener: YES∙Indefinite: "I saw a funny-looking dog today."Writer/Speaker: YESReader/Listener: NO∙Indefinite: "I heard that you once wrote a bookabout ecology."Writer/Speaker: NOReader/Listener: YES∙Indefinite: "I need to buy a new belt."Writer/Speaker: NOReader/Listener: NO* adapted from Brown, R., A First Language. Cambridge,MA: Harvard University Press, 1973.Five Sources of DefinitenessThere are five principal ways in which a reader/listener can know specifically what a noun is referring to (that is, five reasons a noun might be considered definite):1.The noun has been previously mentioned.o I saw a funny-looking dog yesterday [first mention,indefinite]. It looked like a cross between a Pekineseand a German shepherd. When it saw my cat, thedog ran away [second mention, definite].2. A superlative or ranking adjective makes the noun's identityspecific.o The tallest girl in the class is 6'2" tall. [There can be only one girl who is the tallest.]o Please read the fourth paragraph on page 3. [There can be only one fourth paragraph.]o Today is the most important day of my life. [There can be only one day that is the most important.]3.The noun describes a unique person, place, or thing.o The earth revolves around the sun once every 365 days. [There is only one earth and only one sun--inour solar system, that is!]4. A modifying word, phrase, or clause follows the noun andmakes it clear which specific person or thing you arereferring to. But not every noun that is modified in this way is definite; it depends largely on the situation and on what you can reasonably expect your listener/ reader to know about.o Do you remember the girl who went camping with us?[Using the here implies that there was only one girlwho went camping with you; otherwise the clausewho went camping with us would not be sufficient toidentify the particular girl that you are referring to. Ifthere were two girls, then you would have to be morespecific, saying perhaps "Do you remember the girlfrom Iowa who went camping with us last May?"] o John is reading a book about quantum physics. [Here the noun book is modified by the phrase aboutquantum physics. But there is undoubtedly more thanone book about quantum physics. Therefore, to makebook definite, we would have to add moreinformation: "the book about quantum physics thatwas assigned by Professor Jackson last week."]5.The context or situation makes the noun's identity clear. Forexample, you might ask someone to "Close the door." You would use the because it would undoubtedly be clear to both of you which door you were referring to. Similarly, if you tell someone that you are going to the library, that person willassume that you are talking about whichever library is most familiar to both of you--RPI's Folsom Library, for example.Again, you have to be sure that your reader or listener has the same context or situation in mind that you are thinking of; otherwise, he or she will be confused by your use of the.For example, one student wrote the following sentence: o This magazine helps women analyze the problematic situation and offers possible remedies.But this was the first time she had mentioned a problematicsituation. Her readers were therefore confused because heruse of the word the implied that they were already supposedto know which problematic situation she was referring to.Choosing the Appropriate ArticleIn order to choose the appropriate article for a noun, you first need to decide whether the noun is singular. One way to determine this is to ask yourself whether you could put the number "one" in front of it. For example, you can say "one experiment," but not "one knowledge" or "one examples"; therefore, "experiment" is singular, whereas "knowledge" is uncountable and "examples" is plural.Table 3 below shows that if the noun is singular, you must use either "the" or "a"/"an" in front of the noun, depending on whether it is definite (known to both you and your readers) or not.If the noun is not singular, then it must be either plural or uncountable. Table 3 below shows that article usage is the same for both plural and uncountable nouns will use either "the" or "0" (no article) in front of the noun. Again, the decision depends on whether the noun is definite or not.Table 3: Choosing the Appropriate Article1.Singular Noun (one of something that is countable)Is the noun definite?YES: Use "the"a) The painting in the living room was given to meby an old friend.o Painting and living room are singularbecause we are referring to only onepainting and one living room.o Painting is definite because the followingphrase, in the living room, makes it clearwhich painting we are referring to (reason 4,above). (However, it could be indefinite ifthere is more than one painting in the livingroom that the speaker could be referring to;in that case, the speaker would say "Apainting...."o Living room is definite because it is clearfrom the context of the situation that thespeaker is referring to the living roomclosest to where he and the listener arestanding (reason 5 above).NO: Use "a" or "an"b) Eugene's lunch consisted of a sandwich, twocookies, and a can of soda.o Sandwich and can are both singular (there is only one of each). They could be definiteif the listener/reader had seen Eugene'ssandwich and can of soda, or if they hadbeen mentioned before. However, thespeaker/writer's choice of the indefinitearticle a for both nouns tells us that they areunknown to the listener/reader.2.Plural or Uncountable NounIs the noun definite?YES: Use "the"c) The technical reports that I gave you are topsecret. (plural and definite)o Reports, is plural (note that it ends in -s)because we are talking about more than onereport. It is definite because the followingphrase, that I gave you, makes it clear to thereader/listener which reports you arereferring to (reason 4, above).d) The wool that is produced in Scotland is used tomake sweaters and other garments. (uncountable and definite)o Wool is uncountable (you cannot say one wool). It is definite because the followingclause, that is produced in Scotland, makesit clear which wool you are referring to(reason 4, above).NO: Use 0 (no article)e) Long reports are difficult to write. (plural and indefinite)o Reports is plural (note that it ends in -s). The lack of an article in front of it means that thespeaker/writer is talking not about particularreports that are known to the listener/reader,but about all long reports in general.f) Scotland's major exports are wool and oil. (uncountable and indefinite).o Wool and oil are both uncountable nouns (you cannot say one wool or one oil in thiscontext). They are indefinite because theyrefer to these two substances in general, notto particular shipments of wool and oil thatare known to the reader/listener.LEARNING HINT #2: One of the most common mistakes that non-native speakers make with articles is using a or an with plural or uncountable nouns (a students and a research would be incorrect). But consider that the articles a and an are derived from the word one. Thus, it is illogical to use a or an with a plural noun, isn't it? It is also illogical to use a or an with an uncountable noun--After all, how can you have one of something that is uncountable?An easy way to eliminate a lot of mistakes is to look through your writing for every occurrence of a and an. Then examine the noun that follows each a or an. If the noun is either plural or uncountable, then you have made a mistake, and you should refer to Table 3 to determine whether to use the or 0 instead.LEARNING HINT #3: Often mistakes occur not because a writer has used the wrong article (e.g., a or an instead of the), but because the writer has used no article at all for a singular noun. Notice in Table 3 that every singular noun must have an article in front of it.LEARNING HINT #4: Notice that every definite noun takes the article the, regardless of whether it is singular, plural, or uncountable. Therefore, if you cannot decide whether a noun is singular, plural, or uncountable, go on to the next step and ask yourself whether it is definite (known to both the writer/speaker and the reader/listener) or not. If it is definite, then use the.Using Articles with Proper Nouns (this section is slightly modified for use by ELP)So far, we have been talking only about using articles with common nouns. The rules for proper nouns are more complex.Proper nouns are names of particular people, places, and things (John F. Kennedy, New York City, Notre Dame Cathedral), and for that reason they are inherently definite. Nevertheless, the definite article is not used with most singular proper nouns. For example, if you are referring to your friend George, you wouldn't say "The George and I went to a movie last night." The only times "the" is used with a name like this are: a) when you want to be emphatic, as in "the Elizabeth Taylor" (to emphasize that you are talking about the famous actress, and not about another woman with the same name), and b) when you are actually using the name as a common noun, as in "the George that I introduced you to last night" (the real meaning of this phrase is "the man named George..."). Plural names, on the other hand, are always preceded by the: theJohnsons, the Bahamas, etc.Singular geographical names are very irregular with respect to article usage. For example, singular names of continents (Asia, Africa), mountains (Mount Fuji), and bays (San Francisco Bay) do not take the article the, but regions (the Crimea), deserts (the Sahara), and other geographical entities do.Most place names which include the seem to be structures composed of a noun and a modifier: The United States, the Dominican Republic, the Empire State (New York’s nickname) and The Empire State Building. However, names with New, North, South, East or West do not use the: New York, South Carolina, New South Wales, East Anglia.Great Britain does not use the, but the Great Lakes does. Pennsylvania has both the University of Pennsylvania (in Philadelphia) and Penn State University (in College Park).Indeed, the use of articles with singular proper nouns is complex and hence difficult to learn. For this reason, the best thing to do is to memorize whether the proper nouns that you use frequently are used with or without the.Examples:State StreetDelaware CountyGreat Britainthe(former) Soviet Unionthe University of VirginiaRensselaer Polytechnic InstituteHarvard UniversityOrganizations typically have the in their names. However, the abbreviations may or may not be said with the:The United Nations (the U.N.)The Organization of Petroleum Exporting Countries (OPEC, not ‘the OPEC’)The pattern seems to be that, if the abbreviation is said as one word, it will not take the. On the other hand, if theabbreviation is said as letters, the will be used:The CIAThe FBIUNESCONAFTA"A" Versus "An"This last topic is undoubtedly the easiest, because most non-native speakers already know about the difference between a and an. They are simply two variations of the indefinite article. A is used before words that begin with consonant sounds (a rock, a large park) and an is used before vowel sounds (an interesting subject, an apple).However, note that the choice of a or an depends on pronunciation, not spelling. Many words that begin with the vowel -u- are preceded by a instead of an because the -u- spelling is often pronounce -yu-, as in useful ("a useful idea"), and uranium ("a uranium isotope"). In addition, in a few words borrowed from French, the initial consonant -h- is not pronounced: an heir to the throne, an hour-long lecture, an honorable agreement, etc.A Strategy for SuccessKeep in mind that native speakers of English seldom use articles incorrectly; therefore, any errors that you make are very noticeable and distracting to them. That is why you should make an effort to use articles correctly.Study this handout--particularly Five Sources of Definiteness, Table 3, and the Learning Hints. Memorize the definition of definiteness ("known to both the writer/speaker and thereader/listener"). Then try the Exercise toward the end of this handout; the correct answers are provided on the following page so you can check your work.In the future, whenever you write in English, you will need to proofread your writing carefully and to apply the rules for article usage very deliberately. With practice, you can learn to use articles correctly--not only in writing, but also in speech!References∙Brown, Roger.

This is not one of the five principalsources of definiteness, but in this case, "Roman empire" isvery specific (especially since "Roman" is derived from theproper noun, "Rome"), and the reader would be expected toknow that there was only one empire that is known as theRoman empire in English.2.a) The -- singular; definite because of reason 4 (followingmodification: of the problem...).b) the -- singular; definite because of reason 4 (followingmodification: of the decline and fall of the Roman Empire).c) the -- singular; definite because of reason 4 (followingmodfication: of the Roman Empire).d) the or a -- singular; could be either definite or indefinite.Even though a long string of modifiers follows the noun, thereader still might not be familiar with the variety of causesthat the writer is referring to.e) 0 -- plural; indefinite because the reader has no way ofknowing which different authors the writer is referring to.3.a) the -- singular; definite because of reason 4 (followingmodification: of Edward Gibbon).b) a -- singular; indefinite because there could be more thanone widely accepted basis for modern discussion of theproblem (the modification is not sufficient to make the noununique).c) 0 -- uncountable; indefinite. can be either countable oruncountable; here it is being used in the abstract,uncountable sense. It is indefinite because there could bemore than one modern discussion of the problem (themodification is not sufficient to make the noun unique).d) the -- singular; definite because of reason 1 (previouslymentioned).4.a) the -- singular; definite because of reason 1 (previouslymentioned).b) the -- singular; definite because of reason 4 (followingmodification: of the two Antonines).c) the or 0 -- plural; could be either definite or indefinite. Thewriter's use of the indicates that there were two and only twoAntonine emperors. Use of 0 would indicate that there weremore than two Antonine emperors.5.a) the -- singular; definite because of reason 4 (followingmodification: of the Roman conquest).b) the -- Conquest in this context is uncountable, meaning"the area or territory which was conquered." Because thepreceding adjective, Roman, is derived from a proper name (Rome), it makes the following noun unique in this context.c) the -- singular; definite. As in 5b, the preceding adjective,Roman, makes it clear which government is referred to in this context. However, note that in another context, it might be necessary to add a following modification in order tomake the noun definite (e.g., "the Roman government of the third century A.D.")d) the -- singular; definite because of reason 1 (previouslymentioned).6.a) The -- singular; definite because of reasons 1 and 5(Roman government was previously mentioned, and it isclear from the context that military government is alsoreferring to the Roman government).b) 0 -- plural; indefinite (not previously mentioned, nor isthere any other source of definiteness).c) an -- singular; indefinite. There could be more than onegroup, other than the barbarians, who constituted ever-growing percentages of the Roman legions; thus,modification is not sufficient to make the noun definite.d) the -- plural; definite. As in 5b and 5c, the precedingadjective, Roman, is sufficient to make it clear which legions are being referred to in this context. In another context,additional modification might be required to make the noun definite (e.g., "the Roman legions that invaded Britian in 6B.C.")7.a) 0 -- plural; probably indefinite. The author is notnecessarily referring to any particular group of victoriouslegions; moreover, even though legions have beenmentioned before, victorious legions have not; thus, thecriterion of previous mention does not apply.b) the -- singular; definite because of reason 1 (previouslymentioned).c) a or the -- singular; If we interpret when it most needed...as modifying time, then time is definite because of reason 4.However, most native speakers interpret both at a time and when it most needed... as adverbial modifiers modifyingweakening, so the the noun would be interpreted as being indefinite.d) the or 0 -- Strength can be either uncountable (theabstract quality of strength) or singular (a particular instanceof that abstract quality). So it is either singular and definite because of reason 4 (following modification: to overcome other problems), or uncountable and indefinite. Both would be equally acceptable, so it just depends on how the writer is thinking.e) 0 -- plural; indefinite (other problems have not been mentioned previously, and there is no other source of definiteness).。

ArticlesWhat this handout is aboutBecause the article system is so complex and often idiosyncratic, it is especially difficult for non-native English speakers to master. This handout explains three basic rules that are the foundation of the article system and two basic questions that will help you choose the correct article in your writing. It provides examples of articles being used in context, and it ends with a section on special considerations for nouns in academic writing.Using this handoutAs you use the handout, try to keep three things in mind:First, this handout will be most effective if you use it as a tool. Every time you read this handout, read it along side another piece of writing (a journal article, a magazine, a web page, a novel, a text book, etc.). Locate a few nouns in the reading, and use the handout to analyze the article usage. If you practice a little bit at a time, this kind of analysis can help you develop a natural sensitivity to this complex system.Second, using articles correctly is a skill that develops over time through lots of reading, writing, speaking and listening. Think about the rules in this handout, but also try to pay attention to how articles are being used in the language around you. Simply payingattention can also help you develop a natural sensitivity to this complex system.Finally, although using the wrong article may distract a reader’s attention, it usually does not prevent the reader from understanding your meaning. So be patient with yourself as you learn.Basic rulesThis is a simple list, but understanding it and remembering it is crucial to using articles correctly.Rule # 1: Every time a noun is mentioned, the writer is referring to:1. All of them everywhere,2. One of many, or3. This one exactlyRule # 2: Every kind of reference has a choice of articles:1. All of them everywhere…(Ø, a/an, the)2. One of many……………..(Ø, a/an)3. This one exactly…………(Ø, the)(Ø = no article)Rule # 3: The choice of article depends upon the noun and the context. This will be explained more fully below.Basic questionsTo choose the best article, ask yourself these questions:1. “What do I mean? Do I mean all of them everywhere, one of many, or this one exactly?”2. “What kind of noun is it? Is it countable or not? Is it singular or plural? Does it have anyspecial rules?”Your answers to these questions will usually determine the correct article choice, and the following sections will show you how.When you mean “all of them everywhere”Talking about “all of them everywhere” is also called “generic reference.” We use it to make generalizations: to say something true of all the nouns in a particular group, like an entire species of animal.When you mean “all of them everywhere,” you have three article choices: Ø, a/an, the. The choice of article depends on the noun. Ask yourself, “What kind of noun is it?”1. Non-count nouns = no article (Ø)a. Temperature is measured in degrees.b. Money makes the world go around.2. Plural nouns = no article (Ø)a. Volcanoes are formed by pressure under the earth’s surface.b. Quagga zebras were hunted to extinction.3. Singular nouns = thea. The computer is a marvelous invention.b. The elephant lives in family groups.Note: We use this form (the + singular) most often in technical and scientific writing togeneralize about classes of animals, body organs, plants, musical instruments, andcomplex inventions. We do not use this form for simple inanimate objects, like books or coat racks. For these objects, use (Ø + plural).1. Singular nouns = a/an (when a single example represents the entire group)In certain situations, we always use “a” or “an.” These situations include:1. Referring to something that is one of a number of possible things.Example: My lab is planning to purchase a new microscope. (Have you chosen oneyet? No, we’re still looking at a number of different models.)2. Referring to one specific part of a larger quantity.Example: Can I have a bowl of cereal and a slice of toast? (Don’t you want thewhole box of cereal and the whole loaf of bread? No, thanks. Just a bowl and aslice will be fine.)3. With certain indefinite quantifiers.Example: We met a lot of interesting people last night. (You can also say “a bunchof” or “a ton of” when you want to be vague about the exact quantity. Note thatthese expressions are all phrases: a + quantifier + of.)Exception: “A few of” does not fit this category. See Number 8 in the next sectionfor the correct usage of this expression.4. Specifying information associated with each item of a grouping.Example: My attorney asked for $200 an hour, but I’ll offer him $200 a weekinstead. (In this case, “a” can substitute for the word “per.”)5. Introducing a noun to the reader for the first time (also called “first mention”). Use“the” for each subsequent reference to that noun if you mean “this one exactly.”Example: I presented a paper last month, and my advisor wants me to turn thepaper into an article. If I can get the article written this semester, I can take abreak after that! I really need a break!Note: The writer does not change from “a break” to “the break” with the second mentionbecause she is not referring to one break in particular (“this break exactly”). It’sindefinite—any break will be fine!!When you mean “this one exactly”Talking about “this one exactly” is also called “definite reference.” We use it when both the reader and the writer can identify the exact noun that is being referred to.When you mean “this one exactly,” you have two article choices: Ø, the. The choice of article depends on the noun and on the context. Ask yourself, “What kind of noun is it?”1. (Most) Proper nouns = no article (Ø)a. My research will be conducted in Luxembourg.b. Dr. Homer inspired my interest in Ontario.Note: Some proper nouns do require “the.” See the special notes on nouns below.2. Non-count nouns = thea. Step two: mix the water with the boric acid.b. The laughter of my children is contagious.3. Plural nouns = thea. We recruited the nurses from General Hospital.b. The projects described in your proposal will be fully funded.4. Singular nouns = thea. Bring the umbrella in my closet if it looks like rain.b. Did you get the visa you applied for?In certain situations, we always use “the” because the noun or the context makes it clear that we’re talking about “this one exactly.” The context might include the words surrounding the noun or the context of knowledge that people share. Examples of these situations include:1. Unique nounsa. The earth rotates around the sun.b. The future looks bright!2. Shared knowledge (both participants know what’s being referred to, so it’s notnecessary to specify with any more details)a. The boss just asked about the report.b. Meet me in the parking lot after the show.3. Second mention (with explicit first mention)a. I found a good handout on English articles. The handout is available online.b. You can get a giant ice cream cone downtown. If you can eat the cone in fiveseconds, you get another one free.4. Second mention (with implied first mention—this one is very, very common)a. Dr. Frankenstein performed a complicated surgery. He said the patient isrecovering nicely. (“The patient” is implied by “surgery”—every surgery has apatient.)b. My new shredder works fabulously! The paper is completely destroyed. (Again,“the paper” is implied by “shredder.”)5. Ordinals and superlatives (first, next, primary, most, best, least, etc.)a. The first man to set foot on the moon…b. The greatest advances in medicine…6. Specifiers (sole, only, principle, etc.)a. The sole purpose of our organization is…b. The only fact we need to consider is…7. Restricters (words, phrases, or clauses that restrict the noun to one definite meaning)a. Study the chapter on osmosis for the test tomorrow.b. Also study the notes you took at the lecture that Dr. Science gave yesterday.8. Plural nouns in partitive -of phrases (phrases that indicate parts of a larger whole)(Note: Treat “of the” as a chunk in these phrases—both words in or both words out)a. Most of the international students (emphasis on part of the group)b. Most international students (emphasis on the group as a whole)c. Several of the risk factors (emphasis on part of the group)d. Several risk factors (emphasis on the group as a whole)e. A few of the examples (emphasis on part of the group)f. A few examples (emphasis on the group as a whole)Note:“Few examples” is different from “a few examples”. Compare:The teacher gave a few good examples. (emphasizes the presence of good examples) The teacher gave few good examples. (emphasizes the lack of good examples)Article flowchartFor the more visually oriented, this flowchart sketches out the basic rules and basic questions.Some notes about nounsUncountable nounsAs the name suggests, uncountable nouns (also called non-count or mass nouns) are thingsPlaces (collective, regional, “the”): the Great Lakes, the Middle East, the Caribbean Note: Proper nouns in theory names may or may not take articlesWhen a person’s name is part of a theory, device, principle, law, etc., use “the” when the name does not have a possessive apostrophe. Do not use “the” when the name has an apostrophe. Examples:the Doppler effect Einstein’s theory of relativitythe Pareto index Murphy’s lawthe Reimann hypothesis Halley’s cometNote: Articles change when proper nouns function as adjectivesNotice how the article changes with “Great Lakes” in the examples below. When place names are used as adjectives, follow the article rule for the noun they are modifying.Examples:I’m studying ……the Great Lakes. (as noun)…a Great Lakes shipwreck.(as adjective with “one of many” singular noun)…the newest Great Lakes museum. (as adjective with “this one exactly” singularnoun)…Great Lakes shipping policies. (as adjective with “one of many” plural noun)…Great Lakes history. (as adjective with “one of many” uncountable noun)。
