One of the key skills that helps you move from simply “understanding the words” to “truly comprehending the message” is being able to identify the author’s purpose and the structure they use to present their ideas. This skill is incredibly valuable, whether you’re preparing for English reading exams in SAT, IELTS, or TOEFL, or simply aiming to improve your English for study, work, or everyday communication.
Why Are Structure and Purpose Important?
In English texts, especially academic articles, news, or literature, authors typically write with a clear purpose and use a deliberate structure to organize their message.
If you can analyze:
- What the author is trying to say (What is the message?)
- How the content is structured (What method of organization is used?)
- What role each sentence plays (Is it explaining, contrasting, transitioning?)
You’ll understand texts more deeply and develop the ability to write and speak with logical flow and clarity.
3 Common Types of “Structure and Purpose” Questions in English Reading Exams for SAT, IELTS, TOEFL
1. What is the Author’s Purpose?
These questions ask:
What is the author trying to communicate?
Common purposes include:
- To explain
- To argue
- To introduce
- To criticize
- To illustrate
Sample Question: Purpose
In 2007, computer scientist Luis von Ahn was working on converting printed books into a digital format. He found that some words were distorted enough that digital scanners couldn’t recognize them, but most humans could easily read them. Based on that finding, von Ahn invented a simple security test to keep automated “bots” out of websites. The first version of the reCAPTCHA test asked users to type one known word and one of the many words scanners couldn’t recognize. Correct answers proved the users were humans and added data to the book-digitizing project.
What is the main purpose of this passage?
A. To discuss von Ahn’s invention of reCAPTCHA
B. To explain how digital scanners work
C. To highlight von Ahn’s book-digitizing project
D. To show how popular reCAPTCHA is
Correct Answer: A
Explanation: The passage centers around von Ahn’s invention, reCAPTCHA, explaining its origin and function. Therefore, the author’s purpose is to discuss the invention.
2. How Is the Text Structured?
These questions ask about the overall organization of the passage. Common structures in English reading exams for SAT, IELTS, or TOEFL include:
- Cause and Effect
- Problem and Solution
- Comparison/Contrast
- Extended Metaphor
- Chronological Narrative
Sample Question: Structure
From Gwendolyn Bennett’s poem “Street Lamps in Early Spring”:
Night wears a garment / All velvet soft, all violet blue… / And over her face she draws a veil / As shimmering fine as floating dew… / And here and there / In the black of her hair / The subtle hands of Night / Move slowly with their gem-starred light.
What best describes the structure of the passage?
A. Alternating descriptions of night in rural and urban areas
B. A contrast between nightfall and sunrise
C. An extended comparison of night to a human being
D. A description of how night changes with the seasons
Correct Answer: C
Explanation: The poem personifies “night” as a woman, using metaphors like “garment,” “veil,” “hair,” and “hands.” This is a clear example of an extended metaphor.
3. What Is the Function of This Sentence?
These questions ask:
What role does a particular sentence play in the passage?
It may:
- Highlight the main idea
- Provide an example
- Mark a transition
- Establish tone
- Offer a conclusion
Sample Question: Function
From The Fatal Garland by Srimati Svarna Kumari Devi:
Shakti is walking near a riverbank that she visited frequently during her childhood. She crossed the woods she knew so well. The trees seemed to extend their branches like welcoming arms. They greeted her as an old friend. Soon she reached the river-side.
What is the function of the underlined portion in the overall passage?
A. It suggests Shakti feels uncomfortable near the river.
B. It indicates she is lost in the woods.
C. It emphasizes Shakti’s sense of belonging in the landscape.
D. It shows appreciation for her friendships.
Correct Answer: C
Explanation: The imagery (“welcoming arms,” “greeted her as an old friend”) shows Shakti’s deep emotional connection to the place—she belongs there. This is emphasized through personification.
