Skimming, Scanning and Contextual clues

On night, our lesson is skimming and scanning. What is skimming and scanning? Skimming refers to the process of quickly identifying the main idea within a passage. It;s done at a speed three or four times faster than normal reading. Scanning is a reading skill used to find specific information quickly. When scanning for information, we only took for the key words and have a question in mind. After a while, Miss Zu teaches us contextual clues. Briefly, it's help the readers to understand of the new word. There are four types of contextual clues:

1. Examples
2. Synonyms and Definitions
3. Antonyms and  contrasts
4. Experience or sense of the sentence
