The cause/effect pattern discusses causes and effects, with signal words like cause, reasons, and because. The main idea sets up what will be compared or connects a cause to an effect.
Understanding paragraphs
This document defines a paragraph and provides examples to practice identifying paragraphs. It begins by stating that a paragraph is a group of sentences about one topic or idea. Then, it provides two passages and asks the reader to check if they are paragraphs or not. The first passage is about highly paid sports stars in the US and is marked as a paragraph. The second passage touches on several unrelated topics, like tea in England and rice in East Asia, so it is marked as not being a paragraph. The document encourages practicing identifying paragraphs.
Scanning
Scanning is a fast reading technique where the reader moves their eyes quickly over a text to find specific information rather than reading every word. When scanning, the reader focuses only on words that will help answer their question or find the needed information in sources like lists, ads, articles, and web pages. Exercises can help readers learn to scan more efficiently by moving their eyes across the page more quickly to recognize words faster and improve comprehension. Scanning is a useful skill that can help people find information faster in their everyday lives, at school, and at work.
