This document provides instructions and examples for how to preview a text by skimming key elements like the first and last sentences of paragraphs, titles, headings, introductions, tables of contents, pictures, and indexes. Previewing helps the reader form an initial impression of the topic before reading in-depth. The document includes exercises where the reader previews passages and diagrams to predict what they may be about based on these previewing techniques.

1. Previewing

4. Before you start to play tennis, for
example, you usually do warming up.
Otherwise, you may have a lot of
difficulties. This is a good idea in reading.
Look before you read. Then it is much
easier to understand. That is what you do
when you preview.

5. Research shows that it is easier to
understand what you are reading if you begin
with a general idea of what the passage is
about. Previewing helps you form a general idea
of the topic in your mind.
To preview, read the first sentence of each
paragraph and the last sentence of the passage.
You should do this as quickly as possible.
Remember, you are not reading for specific
information, but for an impression of the topic.

6. Exercise
Directions:
Preview the following passage. Focus on
the first sentence in each paragraph and
the last sentence of the passage. Can you
identify the topic?

7. A black hole is a region of space
created by the total gravitational collapse
of matter. It is so intense that nothing, not
even light or radiation, can escape. In
other words, it is a one-way surface
through which matter can fall inward but
cannot emerge.
Some astronomers believe that a black
hole may be formed when a large star
collapses inward from its own weight.

8. So long as they are emitting heat and light
into space, stars support themselves
against their own gravitational pull with the
outward thermal pressure generated by
heat from nuclear reactions deep in their
interiors. But if a star eventually exhausts
its nuclear fuel, then its unbalanced
gravitational attraction could cause it to
contract and collapse. Furthermore, it
could begin to pull in surrounding matter,
including nearby comets and planets,
creating a black hole.

9. There are several ways of previewing a
text book:
1. Read the titles and headings
2. Read the table of contents
3. Read the introduction
4. Look at the pictures (if there are any)

6. Read the index

the content of a book or article.
1. Look at the picture below and try to predict what the text
is about. What kind of text do you think it is?

13. 2. Look at the diagrams below and try to predict what the
text accompanying these diagrams is about. Give
reasons for your answer.

14. III. Previewing using an introduction, table of
contents, blurb, and index of a book.
Read the following introduction, table of
contents, blurb, and index of a book. Then
answer the questions.
1. What is the book about?
2. Which parts would you look at in order to know
what the book is about? Give reasons.
3. What audience was the book written for?
4. Where can you find the evidence whether the
book is a good or bad one?
5. Which part should you check if you want to
know an unknown term quickly?
