✨ Let's Learn About "Do" and "Can"! ✨

Hi friends! 👋 Today, we're going to learn about two super helper words in English: 'Do' (and its pals 'Does' and 'Did') and 'Can'. These words are like little magic keys 🔑 that help us make our sentences ask questions, say 'no', talk about what we are able to do, and ask for things nicely. It’s easy-peasy once you know the rules, so let’s get started and see how to use them!

Uses of Do / Does / Did

The helper word do (and its forms does for singular present, and did for past) is very useful!

1. Making Questions and Saying 'No' (Negatives)

We use do, does, or did to ask questions and to make sentences say "no" for simple present and simple past tenses.

He came. (This is a 'yes' sentence - Affirmative)

He did not come. (This is a 'no' sentence - Negative)

Did he come? (This is a question - Interrogative)

She works. (Affirmative)

She does not work. (Negative)

Does she work? (Interrogative)

2. Not Repeating the Main Verb

To avoid saying the main action word (verb) over and over again, we can just use do, does, or did.

‘Do you know him?’ ‘Yes, I do.’ (This means: Yes, I know him.)

‘She sings well.’ ‘Yes, she does.’ (This means: Yes, she sings well.)

3. Making a 'Yes' Statement Stronger (Emphasis)

Sometimes, we use do, does, or did to make our 'yes' statement sound stronger or more sure.

She did come. (This means she really, truly came!)

You do look upset. (This means you really look upset.)

4. Making Requests Sound Nicer (Persuasive)

When we want to ask someone to do something (an imperative), using do can make it sound more polite or persuasive.

Do be quiet. (Please, be quiet.)

Do come in. (Please, come in.)

Uses of Can

The word can is another super helper! It's often used to talk about what someone or something is able to do.

1. Talking About Ability (What you can do)

Can shows if someone has the skill or power to do something.

He can speak ten languages. (He has the ability to speak them.)

I can knit. (I have the ability to knit.)

Can you lift this box? (Are you able to lift it?)

2. Giving or Asking for Permission (Is it okay to do?)

Can is often used to give permission (like the word may). Nowadays, it's also very common to use can to ask for permission.

You can go now. (I give you permission to go.)

You can take one of those books. (You have permission to take one.)

Can I come in, sir? (Am I allowed to come in?)

3. Talking About Possibility (What might happen)

Can is often used in questions and 'no' sentences (negatives) to talk about if something is possible.

Can this be true? (Is it possible that this is true?)

No, it can’t be. (It's not possible.)

Note: For 'yes' sentences about possibility, we often use may. For example: "It may rain."
