MAIN IDEA IN A PASSAGE
Finding the Main Idea
The main idea is the central point or thought the author wants to communicate to
readers. The main idea answers the question, “What does the author want me to
know about the topic?” or “What is the author teaching me?” Often the author
states the main idea in a single sentence.
In
paragraphs, a stated main idea is called the topic
sentence.
In an article, the stated main idea is called
the thesis
statement.
When
the author does not state the main idea directly, it is called an
implied main idea.
An implied main idea requires you to look at the specific statements in the
paragraph and consider what idea they suggest.
Why
is identifying the main idea important?
Finding
the main idea is key to understanding what you read. The main idea ties all
of the sentences in the paragraph or article together. Once you identify the
main idea, everything else in the reading should click into place. The rest of
the reading is the evidence provided to support that main idea.
Finding the Main Idea
Find
the topic first. You have to know the topic before you can determine the main
idea. Preview your text and ask yourself,
Ø
What is the text about?
Ø
Who is the writer?”
Ø
What is the author teaching me about?
Ø
How did the author provide his information?
Ø
Why did the author write the passage or
article?
You can
answer this by finding the idea that is common to most of the text. Use these
clues to help find the main idea:
1.
Read the first and last
sentences
of the paragraph. Authors often state the main idea near the beginning
or end of a paragraph.
2.
Pay attention to any idea
that is repeated
in different ways. If an author returns to the same thought in several different
sentences, that idea is the main or central thought under discussion.
3.
Look for a
sentence that states the main idea.
This is the stated main idea or topic sentence.
4.
Look for
reversal transitions at the beginning of sentences. These signal that the
author is going to modify the previous idea. When a reversal transition opens
the second sentence of a paragraph, there’s a good chance that the second
sentence is the topic sentence e and a stated main idea.
Some samples of
reversal transitions:
But
Nevertheless
Still
Conversely
Nonetheless
Unfortunately
Even so
On
the contrary
When in fact
However
On the other hand
Yet
In contrast
Regardless
5.
At times the main idea will not be stated
directly.
This is called an implied main idea. Read all of the specific statements, not just
the ones that open the paragraphs. Think of a general statement that could sum
up the specifics.
6. Once you feel sure that
you have found the main idea, test it. Ask yourself if the sentence could act
as a summary of the other sentences in the paragraph.
After Finding the
Main Idea
Do
the examples, reasons, and facts explain or give evidence supporting the main
idea you have in mind?
If
they do, then you are right on target. If they don’t, revise your main idea.
Paragraph
1 Stated Main Idea
What
is motion? Consider a ball that you
notice one morning in the middle of a lawn. Later in the afternoon, you notice
that the ball is at the edge of the lawn, against a fence, and you wonder if
the wind or some person moved the ball. You do not know
if the wind blew it at a steady rate, if many gusts of wind moved it, or even if some
children kicked it all over the yard. All you know for sure is that the ball
has been moved
because it is in a different position after some time passed. These are the two
important aspects of motion: (1) a change of position and(2) the passage of time.
Find the topic first.
Ask:
“What is this paragraph about?” In Paragraph 1, the first sentence asks, “What
is motion?”
The general topic is
motion.
Ask yourself. “What does the author want me to
know about the topic?”
What
does the author want me to know about motion?
Read
the first and last sentences of the paragraph. The last sentence appears to
answer the question “What is motion?” Does this mean that sentence is the
stated main idea?
Once
you feel sure that you have found the main idea, test it.
The topic is motion, and the paragraph
describes a ball being moved over time.
The
other sentences repeat “moved” and “time.” The last sentence includes both of
those ideas.
Stated main idea of the above
passage:
“These are the two important aspects of
motion:
(1) a change of position and
(2) the passage of time.”
Paragraph
1 is actually the start of an article. Not only is the sentence a stated main
idea and the topic sentence of the paragraph, but it is also the thesis for an
article that explains how position and time, and equal motion.

Another Example of the Stated Main Idea
Old
people say that childhood is the best part of Man’s life. They look back at
their childhood and remember all its happy days—the jolly games, the long
rambles in the country, the fun they had at school, the kind father and mother
and little sister and brothers, the old homes, the sweets and cakes they used
to eat, the children’s parties, the jokes they used to play, and the presents
they got. When they were children, they did not work hard to get something to
eat; their mothers gave them all they wanted. The world to them was a very
beautiful place, and they did not know that men could be cruel and hard. They did
know how false and dishonest people could be. So, they sometimes sigh and wish
they could be children again.

Paragraph: Reversal Transitions
Enormous energy, enthusiasm, and organization
drove the reform efforts in America in the late nineteenth and early twentieth
centuries, much of it a result of social crises and political movements in the
United States. But the “age of reform,” as some scholars have called it, was
not an American phenomenon alone. It was part of a wave of social experimentation
that was occurring throughout much of the industrial world. “Progressivism” in
other countries influenced the social movements in the United States. And
American reform, in turn, had a significant influence on other countries as well.
Look for reversal transitions at
the beginning of sentences.
In this Paragraph, the second
sentence begins with “But”
and signals that the author is modifying the previous idea. There’s a good
chance that the second sentence is the topic
sentence and a stated main idea.
To test this, read the third sentence. Since it supports the
second sentence, It is the main idea.
Stated main idea:
But the “age of reform,” as
some scholars have called it,
was not an American
phenomenon alone.
Paragraph
4: Implied Main Idea
The
very name of our country, the United States of America, suggests both unity
and division. To the modern citizen, it
is the unity
that counts, with Americans generally thinking of themselves living in one
country divided mainly by geography. But there was a time when many
Americans thought in distinctly different terms. In 1774 when John
Adams
spoke of "our country," he meant Massachusetts.
Even Thomas
Jefferson
took a while to move beyond his own region of birth and in his early years,
"my country" usually meant Virginia to him.
Consider, too, the original heading for the Declaration of Independence, which
was described as "The Unanimous Declaration of the
Thirteen United States of America."
As Daniel Boorstein has written in The Americans, "An unsuspecting
historian a thousand years hence might assume...that the Declaration brought
into being thirteen new and separate nations...." In 1787, Oliver Ellsworth of
Connecticut participated in making plans for a federal government
that would have power over the entire country. However, his words suggest that
his head and heart were at war with each other. Like many others,
Ellsworth knew that the states should strive for unity. Yet for him, it was his
home state that inspired the strongest patriotic feeling, as he publicly
declared "my happiness depends as much on the existence of my state
government, as a newborn infant depends upon its mother for nourishment."
Ellsworth was not alone in these sentiments.
Implied Main Idea
At
times the main idea will not be stated directly. This is called an implied main
idea. Identify the topic.
The
first sentence in the Paragraph introduces
“United States of America” as suggesting “unity and division.” A preview of the
paragraph shows “state,” “unity,” and “country” repeated throughout. My general
topic is state unity.
Ask
yourself.
“What
does the author want me to know about the topic?”
What does the author want me to know about
state unity?
Read
all of the specific statements, not just the ones that open the paragraphs.
Be
aware of transitions that show relationships or a reversal.
The reversal transition “But” is in the third
sentence. It states
“there was a time when many
to Americans thought in distinctly different terms.”
What
was the thought and when was that time?
Pay attention to any idea that is
repeated in different ways.
The author gives several examples of the founding fathers and their love of their
states.
Think
of a general statement that could sum up the specifics as effectively as any
stated topic sentence.
As
there is no topic sentence, you will have to write one. The main idea you write
must be a complete sentence that contains a subject and a verb and expresses a
complete thought.

Who or What
is this paragraph about? |

When, or Where? |

Once
you feel sure that you have found the main idea, test it.
1. Ask
yourself if the sentence could act as a summary of the other sentences in the
paragraph.
2. Be
sure that none of the sentences contradicts your general statement.
3. Do the
examples, reasons, and facts included in the reading explain or give evidence
supporting the main idea you have in mind?
Implied Main Idea: Early in the history of
the United States, many Americans were more devoted to their own home states
than the idea of a common country.
