Sometimes you might have to identify the topic of a paragraph.
The topic is the main idea of the paragraph.
Each paragraph has one (1) main idea.
![Page 3: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/3.jpg)
To find the main idea, you should be able to answer
a very important question:
Who or what is this paragraph about?
Let’s read a paragraph now and decide what it’s about.
![Page 4: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/4.jpg)
Pets play an important part of many people’s lives. Many kinds of
animals are used as pets, from reptiles to horses. Among the most
common pets are dogs. Dogs help people in many ways. First, they’re
great companions. Many children love the family dog and have a loyal
friend to play with every day. Older people also enjoy the company of
their pet dogs. Dogs also serve humans as work animals, by corralling
sheep, killing rats, and guarding homes and farms. Finally, dogs assist
disabled people in various ways, such as leading the blind, alerting the
deaf, and warning epileptics of impending seizures.

Now ask yourself the following question. Try to answer it in one word.
What is this paragraph about?
![Page 6: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/6.jpg)
Your answer should have been…..
dogsLet’s look at the paragraph again and see why.
![Page 7: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/7.jpg)
Let’s look at the first sentence in the paragraph.
Now ask yourself:
“Pets play an important role in many people’s lives.”
Is this what that whole paragraph is about?
Is the writer telling me that pets are important?
NO! Therefore, this is not the main idea.
![Page 8: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/8.jpg)
Let’s look at the next sentence.
Is the whole paragraph about different kinds of pets?
“Different types of animals can be pets, ranging from reptiles to horses.”
Therefore, this is not the main idea.
![Page 9: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/9.jpg)
Look at the next sentence.
“However, among the most common pets are dogs.”
Is the whole paragraph about how dogs are the most common pets?
No. Therefore, this is not the main idea.
![Page 10: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/10.jpg)
Let’s look at the next sentence.
Does the paragraph tell us about the different ways dogs help people?
“Dogs help people in many ways.”
YES!
![Page 11: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/11.jpg)
The paragraph tells us about many ways that dogs can help people, so that’s the main idea!
Now we need to find the topic sentence, which tells us the main idea of the paragraph.
![Page 12: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/12.jpg)
Let’s look at the first few sentences to see if we can
find the topic sentence.
• Pets play an important part of many people’s lives. Many kinds of animals are used as pets, from reptiles to horses.
Is one of those the topic sentence?
![Page 13: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/13.jpg)
That was just the introduction. It didn’t tell us about the main idea yet. But let’s keep reading.
Aha!
Pets play an important part of many people’s lives. Many kinds of animals are used as pets, from reptiles to horses. Among the most common pets are dogs. Dogs help people in many ways.
![Page 14: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/14.jpg)
Dogs help people in many ways.
What’s the topic sentence?
![Page 15: What ’ s the Main Idea? Understanding Paragraph Structure](https://reader038.vdocuments.site/reader038/viewer/2022102908/56649e2c5503460f94b1b4ed/html5/thumbnails/15.jpg)
You probably noticed that the rest of the paragraph gave us specific information about ways that dogs help people.
Those sentences are called major supporting details because they support (or prove) the main idea.
Now let’s look at those supporting details.

Let’s look at this again.

But there’s more than just the topic sentence and those three major supporting details.
Let’s look at the paragraph again.
That extra information is found in the minor supporting details.
We don’t just want to be told that dogs are good companions. We want to know WHY they’re good companions. We want examples!
