STUDY

Skimming

Skill Example
Skimming is when you read a book or text very quickly to get a general idea of what it is about. You don't read every word. Instead you look at the headings, pictures, and important words to understand the main idea. It's like taking a quick look at something to see if you're interested in it or if it's important to read more closely.

● Look at the title and headings of the text to get an idea of what it is about.
● Look at any pictures or diagrams to see if they help you understand the text better.
● Read the first and last sentences of each paragraph to get an idea of the main points.
● Look for bold or italicized words, or words in a different color, to see if they are important.
● Don't worry about understanding every single word or detail—just focus on getting the main idea of the text.
Look quickly at this paragraph. Don't read every word. Don't use a dictionary.

Did you know that in 2022 there were over 7 billion cell phone users in the world? That's more than half the entire population of the planet! One of the great things about the phone is that it helps people stay connected even when they are far apart. For example, when your uncle lives in another state, you can use the phone to call him and catch up on what's happening in his life. In fact, research shows that people who use their phones to maintain social connections are happier and more satisfied with their lives. Additionally, in emergencies, the phone can be a lifesaver. If someone gets hurt or is in danger, you can use the phone to call for help. So, the phone is a powerful tool that helps us stay connected and safe.

1. Is the paragraph about how telephones work? Or is the paragraph about how telephones are used?
2. Does the writer have a good or bad feeling about telephones?

Scanning

Skill Example
Scanning is a reading skill that helps you find a specific piece of information quickly. You move your eyes quickly over a text to look for a particular word, phrase, or piece of information. It's like looking for a needle in a haystack1 but with words instead of hay. When you scan, you don't read everything in detail. You focus on finding the specific information you need. Scanning can be very useful when you need to find an answer to a question or locate a specific fact in a text.
● Identify the specific information you are looking for, such as a number, a date, a name, a definition, etc.
● Focus on quickly moving your eyes over the text to find the information you need.
● Look for keywords or phrases that are related to the information you are looking for.
● Use headings, lists, charts, transition words (first, next, for example, in addition, etc.) and other formatting features to help you locate the information more easily.
● Don't get distracted by other information in the text—stay focused on finding what you need as quickly as possible.
Look at this paragraph again. Don’t read all the words. Instead, look for these specific pieces of information:

1. How many people had cell phones in 2021?
2. The author likes cell phones for two reasons. What are they?

1According to Cambridge Learner’s Dictionary, a needle in a haystack is a common idiom that means something that is impossible or extremely difficult to find, especially because the area you have to search is too large.
