1. What You’ll Learn

You will learn how to:

  • Identify the topic of a passage
  • Identify the main idea
  • Identify key points that develop the main idea
  • Separate important information from irrelevant details
  • Combine the most important information into a concise summary

2. The Skill/Concept

Step 1: Identify the Topic

What Is the Topic?

The topic is the subject of the passage.

Ask Yourself:

What am I reading about?

The topic is usually a word or short phrase, not a complete sentence.

Example:

Topic: Sepsis
Remember: The topic tells you what the passage is about. It does not tell you what the author is saying about that topic.

Step 2: Identify the Main Idea

The main idea is the author's central message about the topic.

Ask Yourself:

What does the author want me to know about this topic?

Topic vs. Main Idea

Topic

Sepsis

Main Idea

Sepsis can cause harmful changes throughout the body and may lead to serious complications.

Topic + What the author says about it = Main Idea

Step 3: Identify the Key Points

Key points are the important ideas that develop or support the main idea.

Ask Yourself:

What important idea does this paragraph contribute to the passage?

You do not need to remember every sentence.

Instead, try to explain each paragraph in one sentence.

Example:

Main Idea:

Sepsis can cause harmful changes throughout the body and may lead to serious complications.

Key Points:
  • The body's response to an infection can cause widespread harmful changes.
  • Sepsis can interfere with organ function and cause significant changes in the body.
  • Recognizing changes in a person's condition can provide important information about sepsis.
  • Treatment focuses on controlling the infection and supporting affected body functions.

The key points develop and support the main idea.

Step 4: Identify Important Details

Not every detail in a passage belongs in a summary.

Supporting details provide specific information that explains or develops a key point.

Ask Yourself:

Does this information help explain an important idea in the passage?

Example:

Key Point:

Sepsis can interfere with organ function and cause significant changes in the body.

Supporting Details:
  • A person may experience changes in temperature, heart rate, breathing, or mental status.
  • Blood pressure can fall in more severe cases.
  • Organs may not receive enough oxygen and nutrients.

These details help explain the key point.

Irrelevant Details

Some information may appear in the passage but does not directly help communicate the main idea.

A detail can be true and still be irrelevant to the summary.

Ask Yourself:

Does this information help communicate the author's overall message?

If it does, consider including it.

If it does not, leave it out.

3. TEAS-Friendly Strategy / Ask Yourself

When summarizing a multi-paragraph passage, work from big ideas to smaller details.

Ask Yourself:

1. What is the passage about?

4. Guided Example

Sepsis: When an Infection Affects the Whole Body

Sepsis can develop when the body's response to an infection becomes harmful to the body's own tissues and organs. Instead of remaining focused on fighting the infection, the body's response can trigger widespread inflammation and changes throughout the body. Because of this, sepsis can become a serious medical condition that requires prompt attention.

As sepsis progresses, the changes occurring in the body can interfere with the normal function of important organs. A person may experience changes in temperature, heart rate, breathing, or mental status. In more severe cases, blood pressure can fall, and organs may not receive enough oxygen and nutrients to function properly. Severe sepsis can cause dangerously low blood pressure and circulation problems; it can progress to septic shock.

Recognizing changes in a person's condition is an important part of responding to sepsis. Healthcare professionals consider the person's overall condition rather than relying on one sign alone. Changes in vital signs, alertness, breathing, and other aspects of a person's condition can provide essential information about how the body is responding to an infection.

Treatment for sepsis focuses on controlling the underlying infection and supporting the body's affected functions. Healthcare professionals may use medications and supportive treatments based on the person's condition. Because sepsis can worsen quickly, early recognition and treatment are important in reducing the risk of serious complications.

Step 1: Identify the Topic

What am I reading about?
Sepsis

Step 2: Identify the Main Idea

What does the author want me to know about sepsis?
Sepsis can cause harmful changes throughout the body and may lead to serious complications.

Step 3: Identify the Key Points

The passage develops the main idea by explaining that:

  • The body's response to an infection can cause widespread harmful changes.
  • Sepsis can interfere with organ function and cause significant changes in the body.
  • Recognizing changes in a person's condition can provide important information.
  • Treatment focuses on controlling the infection and supporting affected body functions.

Step 4: Identify Important Details

For example:

Key Point:

Sepsis can interfere with organ function and cause significant changes in the body.

Supporting Details:
  • Changes in temperature, heart rate, breathing, or mental status may occur.
  • Blood pressure can fall in more severe cases.
  • Organs may not receive enough oxygen and nutrients.

These details explain how sepsis can affect the body.

Step 5: Put the Important Ideas Together

Now we have:

Main Idea:

Sepsis can cause harmful changes throughout the body and may lead to serious complications.

Key Points:

It can interfere with organ function, changes in a person's condition can provide important information, and treatment focuses on controlling the infection and supporting affected functions.

Summary:

Sepsis occurs when the body's response to an infection causes harmful effects throughout the body. It can interfere with organ function and cause significant changes in a person's condition. Because sepsis can worsen and lead to serious complications, recognizing it early and beginning appropriate treatment are important.
Notice:

The summary does not:

  • Copy every sentence from the passage
  • Include every supporting detail
  • Add personal opinions
  • Focus on only one small example

Instead, it combines the most important information into a concise explanation.

Your Turn

Read the passage below and use the process you learned.

Understanding Obesity

Obesity is a health condition that can affect a person's health and develop from multiple factors. A person's risk may be influenced by genetics, environment, lifestyle habits, and other factors.

When energy intake consistently exceeds the amount of energy the body uses, the excess energy can be stored as body fat. Over time, this can contribute to weight gain. However, body weight is influenced by more than food intake alone.

Obesity can increase the risk of several health conditions. These may include type 2 diabetes, cardiovascular disease, and certain other health problems.

Lifestyle habits can also influence a person's risk of developing obesity. Physical activity, eating patterns, and sleep can all play a role in overall health.
