It is the railway through which your messages will be transported. Without it, in the same way as a train cannot move without railways, you won’t be able to convey your ideas to their full extension.” ~ Julio Foppoli Objectives After finishing this chapter, the reader will be able to... 1. Identify and define different parts of speech, including nouns, verbs, adjectives, adverbs, articles, pronouns, and prepositions. 2. Differentiate between countable and uncountable nouns. 3. Summarize the differences between indefinite and definite articles. 4. Demonstrate how to form comparative and superlative adjectives. 5. Demonstrate how to form comparative and superlative adverbs. 6. Define prepositions and explain why they are difficult for ESL learners. 7. Define verbs and different verb forms, including infinitives, gerunds, present participles, past participles, stative verbs, dynamic verbs, and auxiliary verbs. 8. Name and demonstrate the usage of the twelve tenses of English. 2 Parts of Speech Parts of speech are word categories such as nouns, pronouns, verbs, adjectives, articles, adverbs, prepositions, conjunctions, and interjections. The first part of this chapter discusses different parts of speech, while the second part of this chapter focuses on English tenses. Nouns Nouns denote a person, place, thing, quality, animal, or idea. Nouns can be divided into proper nouns that refer to particular individuals and are capitalized (e.g. Willis Tower, Chicago, International TEFL Academy), and into common nouns, which are not capitalized and refer to objects in general (e.g. tower, city, or academy). In English, nouns are preceded by articles and adjectives: a happy student article adjective noun Countable and Uncountable Nouns: Nouns can also be divided into countable and uncountable (or “non-count” nouns or “mass” nouns). Countable nouns can be singular or plural (e.g. animal/animals, cat/cats, man/men, child/children), while uncountable nouns cannot be divided into separate elements (e.g. money, furniture, coffee, and love). ESL/EFL students need to memorize which words are countable and which ones are uncountable. Some nouns can be both depending on their meaning. For example, “Our house has four rooms” contains a countable version of room. However, “Is there any room for me?” uses an uncountable version of room. The chart below further illustrates the main differences between countable and uncountable nouns. Countable Nouns May be preceded by indefinite article a/an • a banknote Uncountable Nouns (non-count nouns) May not be preceded by indefinite article a/an • a money (“some money” is used) Take final –s/-es in the plural • 2 banknotes Have no plural form; do not take a final –s/-es • moneys May be followed by a verb in singular or plural Always followed by a verb in singular form: form: • Money is important. • This banknote is green. • These banknotes are green. Use the following expressions: • many, a few / few o How many banknotes do you have? o I have a few banknotes. o I have few banknotes left. Use the following expressions: • much, a little / little o How much money do you have? o I have a little money. o I have little money left. 3 Regular and Irregular Plurals: All countable nouns have singular and plural forms. To make a plural form, we usually need to add –s, for example, one apple becomes two apples; however, some nouns have irregular plurals, for example, man becomes men. The chart below will help you understand regular and irregular plural forms. Regular Plural Nouns -s • songs, books, pencils -es (words ending in -s, -sh, -ch, -x, -z) • messes, brushes, churches, boxes -es (some words ending in -o) • potatoes, tomatoes, heroes Irregular Plural Nouns** • man men • woman women • child children • person people • mouse mice • foot feet • tooth teeth • 1 goose 2 geese • 1 deer 2 deer • 1 fish 2 fish • 1 sheep 2 sheep -ies (most words ending in –y preceded by a consonant)* • baby babies, sky skies -ves (some words ending in –f or –fe) • knifeknives, half halves *Note: we do not add –ies to words that end in –y preceded by a vowel, e.g. toy becomes toys; key becomes keys. **These are just some examples of irregular plural nouns. For a complete list, consult a comprehensive grammar book. Pronouns Pronouns replace nouns in order to avoid repetition. In the sentence below, she is a pronoun that replaces the proper noun Lizzy. Lizzy is a happy girl. She smiles all the time. The chart below contains personal subject pronouns. Person 1st 2nd 3rd Singular I you she/he/it Plural we you they 4 This chart shows the other types of pronouns. Person Subject pronoun 1st Person Singular 2nd Person Singular 3rd Person Singular (male) 3rd Person Singular (female) 3rd Person Singular (object) 1st Person Plural I Possessive adjective my Possessive pronoun mine Object pronoun me Reflexive pronoun myself you your yours you yourself he his his him himself she her hers her herself it its its it itself we our ours us ourselves 2nd Person Plural you your yours you yourselves 3rd Person Plural they their theirs them themselves Verbs Most verbs are action words (sing, watch, run, jump). Sometimes, verbs express a state of being (be, exist) or occurrence (happen, become). Infinitives: The base form or bare infinitive is the form of the verb that one can find in a dictionary, e.g. walk, study, or draw. Sometimes teachers write a verb preceded by the particle to (to walk, to study, to draw) to indicate that it is the infinitive form of the verb. Regular and Irregular Verbs: Verbs can be divided into regular and irregular depending on how they form the past tense. See the chart below for examples. Regular verbs Infinitive work listen decide study be (am, is, are) have Irregular do verbs eat break put Past Simple worked listened decided studied Past Participle worked listened decided studied was/were had did ate broke put been had done eaten broken put 5 Gerunds and Present Participles: Other forms of verbs include gerunds and present participles. A gerund is a verb ending with –ing that functions as a noun. A present participle has the same form, but it functions as a verb. Gerund = verb + -ing that functions as a noun Present Participle = verb + -ing that functions as a verb walk walking read reading swim swimming Compare: I like reading. (Here like is a verb and reading is a noun) Reading is my favorite leisure activity. (Here reading is a noun) I am reading now. (Here reading functions as a verb) I have been reading for the past three hours. (Here reading functions as a verb) Verbs Followed by Gerunds and Infinitives: Certain verbs in English are always followed by infinitives, while other verbs are followed by gerunds. Look at the examples below. Infinitives vs. Gerunds Verbs Followed by Infinitives Verbs Followed by Gerunds want: I want to eat. enjoy: I enjoy eating. decide: He decided to dance. practice: He practiced dancing. choose: I chose to go home. mind: I don’t mind going home. agree: She agreed to dance with me. resume: We resumed dancing. Some verbs can be followed by either a gerund or an infinitive, such as like, start, or begin. I like to read books. / I like reading books. We began to study. / We began studying. It started to rain. / It started raining. Stative and Dynamic Verbs: Stative verbs (or non-continuous verbs) are verbs that cannot be converted to a present participle, i.e. you cannot add an –ing ending. These verbs are things you cannot see someone doing such as emotion or abstract verbs (e.g. like, love, hate, want, need, be), opinion verbs (e.g. know, recognize), possession verbs (e.g. possess, own, belong), and sensory verbs (e.g. taste, smell, see). I want some fruit now. I am wanting some fruit now. (incorrect) She needs your help now. She is needing your help now. (incorrect) He owns that car. He is owning that car. (incorrect) 6 Mixed Verbs: Some verbs can be either dynamic or stative, depending on their meaning in context (e.g. have). These are called mixed verbs. I have a car. (Here, have means own) I am having fun. (Here, have means experiencing) Auxiliary Verbs: Auxiliary verbs are helping verbs. They “help” the main verb express the tense of the sentence. Auxiliary verbs do not carry semantic meaning. Examples of auxiliary verbs include be, do, have, and will. She is teaching. (Here the verb is is helping the main verb teaching, so is is an auxiliary verb) She is a teacher. (Here the verb is carries semantic meaning, so it is the main verb and not an auxiliary verb) Adjectives Adjectives are descriptive words that modify nouns. Adjectives usually precede nouns: This is a cute baby. That is a beautiful flower. She is wearing a colorful dress. Sometimes adjectives follow a describing verb, or copula, as in the following sentences: This baby is cute. This flower is beautiful. The dress is colorful. Adjectives have three forms: the base form, a comparative used to compare two items, and a superlative used to compare three or more items. The chart below shows how to form comparatives and superlatives. One syllable Two syllables ending in -y Two or more syllables Irregular Adjectives Base Form of Adjective small old happy pretty difficult beautiful good bad Comparative smaller older happier prettier more difficult more beautiful better worse Superlative smallest oldest happiest prettiest most difficult most beautiful best worst 7 Articles Articles are types of adjectives that give information about nouns. English has two articles: the definite article, the, and the indefinite article, a/an. We use the to modify specific or particular nouns, while we use a/an to refer to non-specific or non-particular nouns. When referencing nouns in general, we do not commonly use articles (often represented with a Ø symbol). the = definite article a/an = indefinite article Ø = no article (zero article) For example, if we say, “Let’s go to the restaurant”, we mean a specific restaurant. It is a restaurant that both the speaker and listener know. If we say, “Let’s go to a restaurant”, we mean any restaurant, rather than a specific one. On the other hand, if we say, “Restaurants are expensive.” We are making a generalization about restaurants and no article is used. There are many more rules governing the use of definite, indefinite, and zero articles. Read the chart below for a general overview of these rules. Indefinite Article: a/an Use a before a consonant sound: a pear, a horse, a university Use an before a vowel sound: an apple, an umbrella, an hour Use a/an with non-specific objects: There is a laptop on the table. Use a/an with singular countable nouns: a chair, a friend Other Uses: Definite Article: the Use the before both a vowel and a consonant sound: the apple, the pear Zero article: Ø Zero articles (Ø) can be used to reference nouns in general: Ø Apples are red. Ø Horses are mammals. Use the when the noun is specific: There is a laptop on the table. The laptop has many colorful stickers on it. Use the with countable and uncountable nouns: the chair, the furniture Other Uses: Zero articles (Ø) can be used to make generalizations: Ø Fruit is a healthy snack. Ø Guns shouldn’t be allowed. Ø Articles are challenging to learn. Other Uses: Membership in a group: When the object is unique: a teacher, an American citizen the moon, the Whitehouse With certain proper names: Ø Obama, Ø Uncle Mike Expressions of quantity, with fractions, and with certain numbers: a number of, a lot of, a third, a couple, a hundred With certain geographical and country names: Ø China, Ø Asia, Ø Lake Victoria Used as part of an exclamatory sentence: What a great idea! Before superlatives: the best, the most talented Before ordinal numbers that are followed by a noun: The third day, the fourth child With certain geographical and country names: the Nile, the South Pole, the United States With certain prepositional phrases that do not modify nouns: by Ø car, on Ø time, in Ø trouble 8 Adverbs Adverbs are describing words that usually modify verbs. Adverbs may also modify adjectives, other adverbs, or the whole sentence. She walked slowly. The very old lady walked quite slowly. Consequently, she missed the bus. Like adjectives, adverbs have three forms: the base form, a comparative used to compare two items, and a superlative used to compare three or more items. The chart below shows how to form comparatives and superlatives. Base Form of Adjective Adverbs formed from adjectives by adding -ly Adverbs with the same form as adjectives Irregular adverbs Base Form of Adverb Comparative Adverb Superlative Adverb slow beautiful slowly beautifully more slowly more beautifully most slowly most beautifully hard fast hard fast harder faster hardest fastest good bad well badly better worse best worst Prepositions Prepositions show a relationship between words in a sentence. Prepositions of place, such as on, in, next to, above, and below, describe the spatial relationship between two or more objects. Prepositions of place are relatively easy to teach; however, difficulty arises when teaching higher levels because specific words and phrases are always followed by certain prepositions. Here are some examples: I’m on a bus, but I’m in a car. I’ll see you at 10:00 AM on Monday in 2015. There is a mistake in the picture on page 12. I’m bad at math. (NOT with math) But I’m bad with children. (NOT at children) I’m interested in math. (NOT at math) She accused me of everything. (NOT for) But she blamed me for everything. (NOT of) 9 Verb Tense and Aspect Usually when we think about tenses, we think of three basic categories: the past, the present, and the future. English also has two aspects: perfect and progressive. Tense and aspect are often combined to indicate a specific time reference. Tense and aspect are best understood through examples, which will be presented in the rest of this chapter. It’s important to remember that some languages do not have tenses as we understand them. For example, Mandarin Chinese uses time expressions, such as yesterday or last week, to indicate time reference. A translation from Mandarin Chinese might look like “I eat pizza for lunch yesterday.” In English, we have to conjugate the verb (change eat to ate) to express the same thought: “I ate pizza for lunch yesterday.” Different languages have different numbers of tenses. English has a total of twelve tense and tense-aspect combinations, summarized in the following table. Simple Continuous* Present Present Simple: I do my homework on the weekends. Present Continuous: I am doing my homework now. Past Past Simple: I did my homework yesterday. Past Continuous: I was doing my homework when the telephone rang. Future Future Simple: If I have time, I will do my homework tomorrow. Future Continuous: I will be doing my homework tomorrow morning. Perfect Perfect Continuous* Present Perfect: Present Perfect I have done my Continuous: homework. Here it I have been doing is. my homework since 6:00 AM this morning. Past Perfect: Past Perfect I had done my Continuous: homework before I I had been doing went to bed last my homework for night. three hours before I submitted it. Future Perfect: Future Perfect I will have done Continuous: my homework by I will have been 11:59 PM next doing my Sunday. homework for five hours by the time I finish it. *Continuous aspect is also known as progressive. They are used interchangeably. Thus, present continuous = present progressive. Similarly, present perfect continuous = present perfect progressive. 10 Present Simple The present simple uses the bare infinitive of the verb, except for the third person singular where an -s/-es ending is required: Subject + VERB (+ s/es in third person singular) I like apples. He likes apples. The present simple can be used to describe the following situations as summarized in the table below: Description Routines Generalizations Schedules At present (stative verbs only) Present Simple Explanation To describe repetitive personal actions or habits.
