LESSON 39

ERRORS WITH PREPOSITIONS

Errors with prepositions are among the most difficult errors to catch. Preposition use in English is very complex. For every rule, there seems to be an exception. Recently, there have been more errors involving prepositions in the Written Expression part of TOEFL, and the errors have been more difficult to spot.

Prepositions are used in the following ways:

 

In adverbial phrases that show time, place, and other relationships

 

in the morning

on Pennsylvania Avenue

to the park by a student

After certain nouns

 

 

 

a cause of

a reason for

a solution to

• After certain adjectives and participles

 

 

different from

aware of

disappointed in

After certain verbs

 

 

 

combine with

rely on

refer to

• In phrasal prepositions (twoor three-word prepositions)

according to

together with

instead of

• In certain set expressions

by far

in general

on occasion

at last

Note: In Mini-Lessons for Section 2, found at the end of this section of the Guide, all of these uses for prepositions are explained and practice exercises are provided.

There are two main types of preposition errors that you may see in the Written Expression part of the test:

A) Errors in Preposition Choice

The wrong preposition is used according to the context of the sentence.

Some of the rules for choosing the correct prepositions are given in the Mini-Lessons, but you will never be able to memorize all the rules for preposition use in English. The more you practice, though, the more you will develop a "feel" for determining which preposition is correct in any given situation.

There are two particular situations involving preposition choice that are often tested in Written Expression:

• Errors with from . .. to and between . .. and

Both these expressions are used to give the starting time and ending time. They can also be used to show relationships of place and various other relationships.

He lived in Seattle from 1992 to 1997.

He lived in Seattle between 1992 and 1997.

Route 66 ran from Chicago to Los Angeles.

Route 66 ran between Chicago and Los Angeles.

Section 2 • Guide to Structure and Written Expression 235

Errors usually involve an incorrect pairing of those words, or the incorrect use of other prepositions:

*between A to B

*from X andY

*between A with B

*since X toY

• Errors with since, for,

and in

Since is used before a point in time with the present perfect tense-but never with the past tense. For is used before a period of time with the present perfect and other tenses. In is used before certain points in time (years, centuries, decades) with the past tense and other tenses-but never with the present perfect tense.

He's lived here since 1995.

He's lived here jor two years.

He moved here in 1995.

Errors involve the use of one of these prepositions for another:

*He's lived here in 1995.

*He's lived here since two years. *He lived here since 1995.

.... Sample Items

D

The preposition of should not be used in this phrase. (When most means "majority," it can be used in the phrase most of the. "Most of the people agree ... ," for example. However, in this sentence, most is part of the superlative form of the adjective spectacular, and so cannot be used with of) ...

LESSON 40

ERRORS WITH ARTICLES

Like errors with prepositions, errors with articles are sometimes hard to catch. This is partly because of the complexity of the article system in English, and partly because articles, like prepositions, are "small words" and one's eye tends to skip over errors involving these words.

The basic uses of articles are explained in the chart:

A or an is used before singular nouns when one does not have a specific person, place, thing, or concept in mind:

an orange

a chair

The is used before singular, plural, and non-count nouns when one has a specific person, place, thing, or concept in mind:

the oranges

the oranges

the fruit

the chair

the chairs

the furniture

No article is used hefore non-count nouns or plural nouns when one does not

have specific persons, places, things, or concepts in mind:

(2) orange

(2) oranges

(2) fruit

(2) chair

(2) chairs

(2) furniture

The indefinite article a is used before words that begin with a consonant sound (a chair, a book); an is used before words that begin with a vowel sound (an orange, an ocean liner). Before words that begin with the letters h- and U-, either a or an can be used, depending on the pronunciation of the words.

an honor

a hat

an umbrella

a university

There are also some specific rules for using (or not using) articles that you should be aware of.

• An indefinite article can be used to mean "one." It can also used to mean "per."

a half, a quarter, a third, a tenth

a mile a minute (one mile per minute) an apple a day (one apple per day)

A definite article is used when there is only one example or the thing or person, or when the identity of the thing or person is clear.

The Moon went behind some clouds. (There's only one Moon.) Please open (You know which door I mean.)

Section 2 • Guide to Structure and Written Expression 241

• A definite article is usually used before these expressions of time and position.

the morning

the front

the beginning

the afternoon

the back

the middle

the evening"

the center

the end

 

the top

 

the past

the bottom

 

the present

 

 

the future

 

 

*No article is used in the expression "at night."

A definite article comes before a singular noun that is used as a representative of an entire class of things. This is especially common with the names of animals, trees, inventions, musical instruments, and parts of the body.

The tiger is the largest cat.

My favorite tree is the oak.

The Wright Bothers invented the airplane.

The oboe is a woodwind instrument.

The heart pumps blood.

A definite article is used before expressions with a ordinal number. No article is used before expressions with cardinal numbers.

the first

one

the fourth chapter

Chapter Four

the seventh volume

Volume Seven

• A definite article is used before decades and centuries.

the 1930's

the

1800's

the fifties

the

twenty-first century

• A definite article is usually used before superlative forms of adjectives.

the widest river

the most important decision

• A definite article is used in quantity expressions in this pattern: quantifier + of + the + noun.

many of the textbooks

not much of the paper

some of the water

most of the students

all of the people

a few of the photographs

These expressions can also be used without the phrase of the.

many textbooks

not much paper

some water

most students

all people

a few photographs

A definite article is used before the name of a group of people or a nationality. No article is used before the name of a language.

The Swedish are proud of their ancestors, the Vikings.

She learned to speak Swedish when she lived in Stockholm.

A definite article is used when an adjective is used without a noun to mean "people who are ...."

Both the young and the old will enjoy this movie.

The poor have many problems.

242 Section 2 • Guide to Structure and Written Expression

A definite article is used before a non-count noun or a plural noun when it is followed by a modifier. No article is used when these nouns appear alone.

The rice that I bought today is in the bag.

Rice is a staple in many countries.

Trees provide shade.

The trees in this park are mostly evergreens.

• A definite article is used before the name of a field of study followed by an of phrase. If a field

is used alone, or is preceded by an adjective,

no article is used.

the literature of the twentieth

literature

century

 

the history of the United States

American history

Definite articles are used before the "formal" names of nations, states, and cities. (These usually contain of phrases.) No articles are used before the common names of nations, states, and cities.

the United States ofAmerica

America

the state of Montana

Montana

the city of Philadelphia

Philadelphia

Definite articles are used before most plural geographic names: the names of groups of lakes, mountains, and islands. No article is used before the names of individual lakes, mountains, and islands.

the Great Lakes

Lake Powell

the Rocky Mountains

Mount Washington

the Hawaiian Islands

Long Island

In the Written Expression section, there are three main types of errors involving articles:

A) Incorrect Article Choice

One of the most common errors is the use of a in place of an or vice versa. Fortunately, this is also the easiest type of error to detect. Another error is a or an used in place of the, or the in place of a or an.

.... Sample Items

A eclipse of the Sun may be either total or partial.

A

B

- C -

-- 0 -

An must be used before a noun beginning with a vowel sound such as eclipse.

In a phrase with an ordinal number (such as first) the definite article the must be used. £.
