1. Skimming:

Skimming is a method of quickly going through a text to get the main ideas or a general overview without reading every word. You glance over the material, focusing on headings, subheadings, and key sentences.

Example:

Suppose you pick up a newspaper and want to quickly understand what’s in today’s news. You skim through the headlines, first paragraphs of articles, and images to get an idea of the key topics covered, like political updates or sports scores.

2. Scanning:

Scanning is the process of looking for specific information in a text. Instead of reading everything, you focus on finding a particular detail, word, or phrase.

Example:

If you’re reading a dictionary and you want to find the definition of the word "metaphor," you scan the entries quickly, looking for the word "metaphor" instead of reading all the definitions.

Both techniques are useful in different contexts—skimming helps in getting an overview, while scanning helps locate specific details.
