1. Imperative Form

2. What are imperatives?
Imperatives are used to directly tell someone to do something, sometimes quite strongly. For example, the speaker says to the listener:
Eat vegetables to stay healthy.
Study English harder if you want to study overseas.
Get the car washed this weekend.
Finish the report before you leave for the day.
We used these to make rules of etiquette for the subway.

3. What is the sentence structure?
The sentence structure of imperatives is relatively easy. Take a look at the following:
    verb (plain form) | object / complement
Notice that the structure simply drops the subject of the sentence.
(not okay) You eat vegetables to stay healthy.
(okay) Eat vegetables to stay healthy.
(not okay) You study English harder if you want to study overseas.
(okay) Study English harder if you want to study overseas.

4. Negative form
Negative imperatives add do + not before the plain form of the verb.
Do + not | verb (plain form) | object / complement
Do not eat too much candy.
Do not drive fast in the snow.
Don't forget your cell phone.
Don't go to bed late!

5. How are imperatives used?
The imperative mood is used in the following situations:
Giving instructions:        Log into the computer network.        Check your dictionaries.
Giving orders:        Do your homework!        Eat all of your vegetables!
Giving advice or suggestions:        Quit your job if you really hate it.        Study English every day if you want to be fluent.
Offering something:        Have some more coffee.        Take my jacket if you're cold.

6. Use Imperative Form for Rules

7. Parallel structure
In a list of rules, try to make sure all the sentences are in the same format.
It would look strange and be harder to understand if sentences were in different styles.
Don’t smoke.
You can’t eat food on the subway.
It’s not a good idea to feed the hungry students.

8. Parallel structure
It looks much better and is easier to understand now.
Don’t smoke.
Don’t eat food on the subway.
Don’t sleep in class.
Be polite.
Use earphones if you want to listen to music.
