English learners should become familiar with contractions in order to understand the grammar of what is said quickly. Native English speakers tend to speak quickly and glide over function words such as helping verbs. Most English contractions are contractions of helping verbs, so an understanding of the role these contracted helping verbs play in grammar can help you better understand spoken English.
English learners should feel free to use contractions whenever they speak, but the use of contractions is not required. If you prefer to speak using full helping verb forms, continue to do so, but become familiar with contractions in order to help your understanding.
English contractions are generally used in spoken English, but not in formal written English. However, written English is becoming more informal (emails, notes to friends, etc.) and you will often see these forms in print.
