SENTENCES

Grammar 1.   Definition of a sentence

A sentence is a group of words that expresses a complete thought. Every sentence must have a subject and a predicate. (See Grammar 3-6.) Every sentence begins with a capital letter and ends with a punctuation mark.

That leopard has already killed 400 people. Is it still hungry? Be careful'

Sometimes a sentence may have only one word. (See Grammar 5.)

Listen.       Hurry!

Grammar 2.   Kinds of sentences

There are four different kinds of sentences. A declarative sentence makes a statement. A declara­tive sentence ends with a period.

A volcano in the Canary Islands is for sale.

An interrogative sentence asks a question. An inter­rogative sentence ends with a question mark.

Who would want to buy a volcano?

An imperative sentence gives a command. An imperative sentence ends with a period.

Show me the list of buyers.

An exclamatory sentence expresses excitement. An exclamatory sentence ends with an exclamation point.

They must be crazy!


Grammar 3.   Subjects and predicates in declarative sentences

Every sentence has two main parts, the subject and

the predicate. The subject names what the sentence

is about. The predicate tells something about the

subject.

In most declarative sentences, the subject is the

first part. The predicate is the second part.

A famous sea captain   was often sick. He    suffered from seasickness.

In some declarative sentences, the predicate is the first part. The subject is the second part.

Back and forth rolled   the captain's ship.

Grammar 4.   Subjects and predicates in interrogative sentences

Every interrogative sentence has a subject and a predicate. In some interrogative sentences, the subject is the first part. The predicate is the second part.

Who   solved the mystery? Which clue   was most important?

In most interrogative sentences, part of the predi­cate comes before the subject. To find the subject and predicate, rearrange the words of the inter­rogative sentence. Use those words to make a declarative sentence. (The declarative sentence will not always sound natural, but it will help you.) The subject and predicate of the two sentences are the same.

Why did   the butler   lie about it? The butler   did lie about it why?

Grammar 5.   Subjects and predicates in imperative sentences

Only the predicate of an imperative sentence is spoken or written. The subject of the sentence is understood. That subject is always you.

(You)    Try an underhand serve. (You)   Please show me how to do it

Grammar 6.   Subjects and predicates in exclamatory sentences

Every exclamatory sentence has a subject and a predicate. In most exclamatory sentences, the sub­ject is the first part. The predicate is the second part.

Kotzebue Sound, Alaska,   is frozen over nearly

all of the time!

In some exclamatory sentences, part of the predi­cate comes before the subject.

What terrible weather   that city   has.' (That city   has what terrible weather!)

Grammar 7.   Compound subjects in sentences

A sentence with a compound subject has two or more subjects with the same predicate.

Jesse James and his brother Frank were famous outlaws in the Old West. Cole Younger, James Younger, and Robert Younger were all members of the James gang.

Grammar 8.   Compound predicates in sentences

A sentence with a compound predicate has two or more predicates with the same subject.

The postal workers took in the tailless cat and named him Kojak.

Kojak lives in the post office, catches mice, and earns a salary.

Grammar 9.   Compound sentences

A compound sentence is made up of two shorter sentences joined by a coordinating conjunction. (See Grammar 45.) A compound sentence has a subject and a predicate followed by another subject and another predicate.

G. David Howard set a record in 1978, and it remains unbroken.

Howard told jokes for more than 13 hours, but not all of them were funny.


NOUNS

Grammar 10.   Definition of a noun

A noun is a word that names a person, a place, or a thing.

That brave man crossed the ocean in a rowboat.

Grammar 11.   Singular and plural forms of nouns

Almost every noun has two forms. The singular form names one person, place, or thing.

Only one worker in that factory can name the secret ingredient.

The plural form names more than one person, place, or thing.

Several workers in those two factories can name the secret ingredients.

Grammar 12.   Spelling plural forms of nouns

For most nouns, add s to the singular form to make the plural form.

joke—jokes       character—characters cartoon—cartoons

If the singular form ends in s, ss, sh, ch, or x, add es.

bus—buses           witch—witches
kiss—kisses          fox—foxes
wish—wishes

If the singular form ends in a consonant and y, change the y to i and add es.

spy—spies       discovery—discoveries mystery—mysteries

If the singular form ends in f, usually change the f to v and add es. If the singular form ends in fe, usually change the f to v and add s. There are some important exceptions to these rules. Look in a dictionary if you are not sure of the correct plural form.

half—halves       wife—wives loaf—loaves       knife-^-knives Some exceptions:

roof—roofs       chief—chiefs       safe—safes

If the singular form ends in o, add s to some words and es to others. Look in a dictionary if you are not sure of the correct plural form.

studio—studios       tomato—tomatoes piano—pianos        zero—zeroes

Some nouns change in other ways to make the plural form.

 

child—children

woman—women

mouse—mice

goose—geese

 

 

 

A few nouns have the same singular form and plural form.

sheep—sheep      deer—deer       moose—moose

Grammar 13.   Proper nouns and common nouns

A proper noun is the special name of a particular person, place, or thing. Each word in a proper noun begins with a capital letter.

Then Max stopped in Junctionville and ate a Big Mac.

A common noun is the name of any person, place, or thing.

Then the man stopped in a small town and ate a hamburger.

Grammar 14.   Possessive nouns

The possessive form of a noun shows ownership. Usually the possessive form of a noun is made by adding an apostrophe and s. (See Punctuation 20.)

A piranha's teeth are as sharp as razors.

The possessive form of a plural noun that ends in s is made by adding only an apostrophe. (See Punctua­tion 20.)

Nobody believed the explorers' story.

Grammar 15.   Nouns of address

A noun of address names the person being spoken to. One or two commas separate a noun of address from the rest of a sentence. (See Punctuation 9.)

Where are you going, Ricky?

I told you, Lucy, that I have a rehearsal tonight.

Grammar 16.   Appositive nouns

An appositive noun renames or identifies the noun that comes before it in a sentence. An appositive noun is usually part of a group of words. The whole group of words is called an appositive. One or two commas separate an appositive from the rest of a sentence. (See Punctuation 10.)

A Ford was the preferred car of John Dillinger, the famous gangster.

Even his sister, the president of her own company, would not hire him.


VERBS

Grammar 17.   Definition of a verb

A verb is a word that expresses action or being. The volcano erupted suddenly. It was a terrific surprise.

Almost all verbs have different forms to show differences in time.

Sometimes puffs of smoke rise from the volcano. A huge cloud of heavy gray smoke rose from it last week.

Grammar 18.   Action verbs

Most verbs are action verbs. An action verb ex­presses physical action or mental action.

The committee members banned Donald Duck

comic books.

They disliked the duck's behavior.

Grammar 19.   Linking verbs

Some verbs are linking verbs. A linking verb tells what the sentence subject is or is like. The most common linking verb is be. (See Grammar 23.)

A black and white dog became a mail carrier in

California.

The dog's name was Dorsey.

Grammar 20.   Verb phrases

A verb phrase is made up of two or more verbs that function together in a sentence. The final verb in a verb phrase is the main verb.

The 13,000-pound bell had disappeared. Somebody must have stolen it.

The verbs before the main verb in a verb phrase are helping verbs. The most common helping verbs are forms of be (is, are, am, was, were), forms of have (has, have, had), and forms of do (does, do, did). (See Grammar 23.)

That radio station is sponsoring a contest. The station has already received 45,217 postcards.

Grammar 21.   Agreement of verbs with nouns

Verbs that express continuing action or existence and verbs that express current action or existence are in the present tense. Almost all present-tense verbs have two different forms. These two different forms go with different sentence subjects. The verb in a sentence, or the first helping verb in a sentence,

must agree with the most important word in the subject of that sentence.

One present-tense form of a verb agrees with singular nouns. This verb form ends with s.

A tick sucks blood from larger animals.

The other present-tense form of a verb agrees with plural nouns.

Ticks suck blood from larger animals.

Grammar 22.   Agreement of verbs with compound subjects

The present-tense verb form that agrees with plural nouns also agrees with compound subjects. (See Grammar 7.)

Beth Obermeyer and her daughter Kristen hold a record for long-distance tap dancing.

Grammar 23.   Forms of the verb be

The verb be has more forms than other verbs. Be has three present-tense forms: is, are, and am. Is agrees with singular nouns. Are agrees with plural nouns. Am agrees with the pronoun I.

Mary Lou Retton is a famous gymnast.

Many people are her fans.

I ant a pretty good gymnast, too.

Most verbs have one past-tense form that tells about action or existence in the past. Be has two past-tense forms: was and were. Was agrees with singular noun subjects. Were agrees with plural noun subjects.

The argument was noisy.

Several neighbors were very angry about it.

Grammar 24.   Irregular verbs

Usually the past-tense form of a verb ends in d or ed.

William Baxter invented an important part of the Morse code.

Some verbs change in other ways to form the past tense. These are called irregular verbs. Look in a dictionary if you are not sure of the correct past-tense form of a verb.

Samuel Morse took all the credit.


PRONOUNS

Grammar 25.   Personal pronouns

A personal pronoun is a word that takes the place of one or more nouns.

Superman tried to enlist in the Army during World War II, but he was found unfit to serve.

Grammar 26.   Subject forms and object

forms of personal pronouns

Each personal pronoun has a subject form and an object form. These different forms are used in different ways in sentences. (The pronouns it and you are the same in the subject form and the object form.) These are the subject forms of personal pronouns: I, you, he, she, it, we, they. These are the object forms of personal pronouns: me, you, him, her, it, us, them.

He saw through a wall and read the wrong eye

chart.

The army did not accept him.

Grammar 27.   Antecedents of pronouns

A personal pronoun refers to the noun it replaces. That noun is the antecedent of the pronoun.

Roy Rogers became famous in movies. He was usually accompanied by his horse, Trigger, and his dog, Bullet.

If a personal pronoun takes the place of two or more nouns, those nouns together are the antece­dent of the pronoun.

Roy Rogers and Dale Evans often worked together. They made dozens of movies.

Grammar 28.   Subject-verb agreement with personal pronouns

The present-tense verb form that agrees with singular nouns also agrees with the pronoun subjects he, she, and it.

She tests new planes.

The present-tense verb form that agrees with plural nouns also agrees with the pronoun subjects I, you, we, and they.

They test new planes.

Grammar 29.   Indefinite pronouns

A word that refers to a general group but does not have a specific antecedent is an indefinite pronoun.

Grammar 31.   Possessive pronouns

A personal pronoun that shows ownership is a possessive pronoun.

These possessive pronouns are used before nouns in sentences: my, your, his, her, its, our, their.

These possessive pronouns stand alone in sentences: mine, yours, his, hers, its, ours, theirs.

Are these gym shoes mine, or are they yours?

Unlike possessive nouns, possessive pronouns are not written with apostrophes.

Grammar 32.   Reflexive pronouns

The witness had been talking to himself, You should have bought yourself a ticket.

Grammar 33.   Demonstrative pronouns

A word that points out one or more people or things is a demonstrative pronoun. These four words can be demonstrative pronouns: this, that, these, and those.

If the word this, that, these, or those is followed by a noun, the word is not a demonstrative pronoun. (See Grammar 34.)


ADJECTIVES
