Now that you understand what main ideas are in TOEFL listening, let’s explore strategies to identify them effectively. These tips will help you focus on the speaker’s core message.
In TOEFL lectures, the main idea is often introduced in the first few sentences. Pay close attention to the opening statement to catch the speaker’s core message.
Example: "Today we’ll explore how renewable energy can reduce carbon emissions by replacing fossil fuels." The main idea is likely about renewable energy reducing carbon emissions.
Speakers often repeat or emphasize the main idea to make it clear. Look for phrases like “the key point is” or “most importantly” to identify the main idea.
Example: "The key point is that climate change accelerates biodiversity loss, which is the most important issue we face." The main idea is climate change accelerating biodiversity loss.
As you listen, mentally summarize the speaker’s message every 20–30 seconds. Ask yourself, “What’s the main point so far?” This helps you stay focused on the core idea.
Example: "Urban planning can improve city life by adding green spaces, which reduce stress and improve air quality." Summarize: The main idea is urban planning improving city life through green spaces.
Imagine You’re Listening to a Conversation: "The Industrial Revolution, starting in the 18th century, transformed economies by introducing mechanized production. Factories replaced manual labor, leading to urbanization and new social challenges."
