Purpose
By the end of this lesson, you will be able to apply skimming, scanning, and systematic vocabulary-building as core Reading section skills.Lesson Explanation
This lesson consolidates a foundational skill pair referenced throughout the previous four lessons, and adds a systematic approach to vocabulary study underlying all three Reading task types.SKIMMING means reading quickly to get a general sense of a passage’s topic and structure, without reading every word – moving your eyes over headings, first and last sentences of paragraphs, and any emphasized text. SCANNING means moving your eyes quickly over text specifically to locate a particular piece of information – a name, date, or specific keyword – without reading for overall meaning at all. The recommended sequence is genuinely important: skim first to build an overview (as recommended for Read an Academic Passage in the previous lesson), then scan to locate specific details once you know roughly where to look.
For Read in Daily Life’s visually structured texts (Part 2, Lesson 3), scanning matters especially, since the answer is often a specific detail within a schedule or notice rather than requiring deep comprehension of connected prose. For Read an Academic Passage (Part 2, Lesson 4), skimming for overall structure matters especially, since questions there more often test understanding of an argument’s shape than isolated fact-location.
A genuinely useful, high-value vocabulary-building habit: rather than memorizing long, disconnected word lists, learn new vocabulary IN CONTEXT from real academic-style reading (news articles on academic or scientific topics, or official practice passages), and specifically note words that recur across multiple sources, since genuinely high-frequency academic vocabulary appears repeatedly across many different topics, while rare, topic-specific vocabulary is a poor use of limited study time. Words signaling LOGICAL RELATIONSHIPS between ideas – “although,” “nevertheless,” “consequently,” “furthermore” – are especially high-value, since they directly support following an academic passage’s argument structure, and this same vocabulary category transfers directly to the Writing tasks covered fully in Part 5.
Practice Questions
1. Skim this passage first, then answer: “Urban heat islands – areas within cities that are significantly warmer than surrounding rural regions – result primarily from the replacement of vegetation with pavement and buildings, which absorb and retain heat far more effectively than natural land cover. Consequently, many cities have adopted reflective roofing materials and expanded tree-planting programs, since even modest increases in vegetation can measurably reduce local temperatures.” What is the passage mainly about?
View Answer
The cause of urban heat islands and strategies cities use to reduce them.2. Now scan the passage for a specific detail: what two solutions does the passage mention cities have adopted?
View Answer
Reflective roofing materials and expanded tree-planting programs.3. What word in the passage signals a logical consequence, connecting the cause of heat islands to the cities’ response?
View Answer
“Consequently.”4. According to the passage, why do paved and built-up areas contribute to higher temperatures?
View Answer
They absorb and retain heat far more effectively than natural land cover like vegetation.5. Is “urban heat islands” defined explicitly in the passage, or left for the reader to infer?
View Answer
Defined explicitly, as areas within cities significantly warmer than surrounding rural regions.6. Which reading technique would most efficiently locate the phrase “reflective roofing materials” in a longer version of this passage?
View Answer
Scanning, once skimming has established roughly where solutions are discussed.7. What does the passage suggest about the scale of vegetation increase needed to have a measurable effect?
View Answer
Even modest increases can measurably reduce local temperatures.8. Which word in the passage is a near-synonym for “considerably” or “significantly,” reflecting varied academic vocabulary?
View Answer
“Measurably.”9. If this passage were part of a longer academic text, what would you expect the following paragraph to discuss, based on its structure?
View Answer
Likely more specific detail or evidence about one of the two mentioned solutions.10. What is the relationship between “pavement and buildings” and “vegetation” as presented in the passage?
View Answer
A contrast: pavement/buildings retain heat, while vegetation helps reduce it.11. Why is skimming recommended before scanning, rather than the reverse?
View Answer
Skimming establishes the overall topic and structure, making it easier to know where to scan for a specific detail.12. Name one of the two techniques described in this lesson, and its specific purpose.
