Imperatives

This website contains a good explantion of how to form/use an imperative.

Here is a video that will show you additional ways that we use imperatives. (This is also a good example of how the British use adjectives differently than Americans. The British host says "politer," but Americans say "more polite." Also, he makes a mistake with the superlative in the middle of the video by saying "more shorter." Did you hear how he corrected himself?)
