The Stated Main Idea - Tutor Hints
What is the main idea?
A general statement about the paragraph (or reading selection). The
main idea
is a
sentence that provides the subject for discussion; it is the topic sentence. It is
usually supported by a list of details. If you can tell what the
supporting details
have in common, you can discover the main idea.
Example 1:
1There are many kinds of unusual plants. 2Cactuses, for instance, can survive in the
great heat of the desert sun at noon and in the bitter cold of the desert at night.
3Instead of regular leaves, they have needles that serve as a defense against
hungry animals. 4Their stems are full of hollow cells that store enough water to
last for months. 5These features make the cactus a remarkable plant, able to live
in one of nature’s harshest environments.
What is the main idea of this passage?
Helpful hints:
• A reading selection is likely to have three kinds of sentences: a
main idea
,
supporting details
, and sometimes a general or catchy
introduction
. The
main idea
can be found
anywhere
among these.
• Read the paragraph out loud to yourself, if possible, and think…
what
or
who
the paragraph is about.
• The
main idea
is usually general—though only general enough to encompass
the list of
details.
It will rarely contain specific information such as dates,
numbers, and examples.
• The
main idea
will
sometimes
contain clue words that give a name to the list
of
supporting details:
o “There are several kinds of…”
o “Use the following steps to…”
o “For these reasons…”
o “There are several ways to…”
• Contrasting transition words like “However”, “But”, and “Yet” often begin the
main idea
, as in the following example.
Example 2:
1You may think golf is difficult. 2However, there are several easy ways to improve
your golf score. 3First, try holding the club with your…
Sentence 1 is a general introduction; it is not the main idea because the author
does not give details about golf being “difficult.” Sentence 2 is the main idea
because a list of details supports it. The word however is the contrasting
transition that shifts the reader’s focus from the introduction to the main idea.
