Most students begin learning language with the misconception that vocabulary building skills and understanding of grammar will enable them to speak well and quickly. I have known 1,000's of students that knew 1,000's of vocabulary words and have an excellent understanding of grammar rules, but they are unable to hold a simple conversation.

In that way, they will be able begin to quickly mimic patterns used by the native speaker. The native speaker will use at least 100 out of 150 patterns within an hour of conversation.
You can put your students on the fast track by focusing their attention on La Bonte's Top 100 English Conversation Patterns.
