Should, need and mustn't

What are we learning today?

You will learn to give advice, to say what is necessary and to say what is not allowed.

Explanation

• Use should for advice: "You should help your neighbours."
• Use need to for something necessary: "You need to take an umbrella."
• Use must for a strong rule.
• Use mustn't for something that is not allowed: "You mustn't leave rubbish in the yard."
• After should and must, use the base verb without "to".
• For a question, put should first: "Should we go?"

Examples

1. No one should miss this.
2. They mustn't talk in the cinema.
3. You mustn't park near the school gate.

Remember!

• Say "He mustn't run", not "He mustn't to run".
• Do not add -s to should and must.
