This lesson covers the imperative form, which is used to give orders, warnings, or advice. The imperative is formed using the infinitive verb form without "to" and can be made negative by adding "do not" or "don't." The imperative form is the same for all subjects but can include yourself by adding "Let's." Being polite with imperatives involves adding "please." The lesson also discusses using "can" and "can't" to express abilities in positive and negative forms and switching words to make sentences interrogative with "Can." Finally, it covers using "could" for abilities in the past tense.

2. Lesson 9
In this lesson we are going to study:
● Imperative
● Can and can't
● Abilities

3. Imperative Form
"Stop!," "Come here!," and "Look out!" are all
examples of the imperative form.
You can use the imperative form to give an order,
a warning, or some advice.

4. Imperative Form
To form the imperative, use the infinitive form of
the verb without "to." To make a negative
imperative, put "do not" or "don't" in front of the
verb, as in, "Don't touch that!"

5. Imperative Form
The imperative is formed the same for all
subjects (you, he, we, they), but you can include
yourself in the imperative by adding "Let's," as in,
"Let's go for a swim."

6. Imperative Form
If you want to be more polite when using an
imperative, just add "please." For example,
"Please leave me alone. I'm trying to learn
English!"

7. Can and Can't
The verb “can” means you are able to do
something:
- I can beat you

8. Can and Can't
To turn the sentence into the negative form you
just need to add “NOT”:
- I can not (cannot, can't) beat you

9. Can and Can't
To turn the sentence into the interrogative form
you just need to switch the words, the “CAN”
goes before the subject:
- Can I beat you?

10. Could
To turn the sentence into the Past you must use
“could”.
- You could be better than you are.
