Answer:
Let's start with activity number 4:
Be quiet! - Don't talk!
Walk slowly! - Don't run!
Come home early! - Don't be late!
Stay in! - Don't go out!
Use a pencil! - Don't write with a pen!
Now, let's do activity number 5. According to the instructions, we can use the imperative in the negative or the affirmative form, according to the pictures:
1. Wash your hands!
2. Don't ride your bike here!
3. Don't go near that dog!
4. Be back home before 12:00!
5. Stop playing that game!
6. Don't shout, please!
Explanation:
Both activities focus on the use of the imperative mood. Imperative sentences are used to give orders or suggestions. In the affirmative form, they start with the base form of the verb, that is, its infinitive form without "to". For example:
- Go away!
- Take your umbrella with you.
In the negative form, imperative sentences begin with "don't":
- Don't forget to call me.
- Don't drive after drinking alcohol.
