Today's lesson will help you answer questions in English with confidence.

 

Auxiliary verbs: notice how there are two verbs in each of the following sentences:

 

- I have lost my car keys.

- James can’t come to dinner tonight.

- My house was built thirty years ago.

- Where do you live?

 

In these examples, the first verbs in each sentence (have, can’t, was, do) are auxiliary verbs. Auxiliary verbs are considered helping verbs.

 

Examples:

Be (am, are, is, was, were, being), can, could, do (does, did) have (has, had, having), may, might, must, should, will, would.

 

Below are some common uses for auxiliary verbs:

 

✅ Use 1:

We use an auxiliary verb without the rest of the sentence when we don’t want to repeat something: 

 

- He could lend me his computer but he won’t. = He won’t lend me his computer.

 

- “Did you lock the door?”

“Yes, I did.” = Yes, I have locked the door.

 

- “Are you mad at me?”

“No, I’m not.” = No, I am not mad at you.

 

- Janet wasn’t studying but Bill was. = Bill was studying.

 

We use do, does, and did for the present simple and past simple:

 

- “Do you like mushrooms?”

“Yes, I do.” = Yes, I like mushrooms.

 

- “Does your daughter like scary movies?”

“She did but she doesn’t anymore.” = She liked scary movies but she doesn’t like them anymore.

 

- “Did you enjoy dinner?”

 “Yes, I did.” = Yes, I enjoyed dinner.

 

✅ Use 2:

We use have you?, isn’t he?, do they?, etc. to show polite interest in what somebody has said:

 

- “I’ve just come from Frank’s place.”

“Oh have you? How is he?” 

 

- “It was beautiful every day of our trip.”

“Was it? That’s great.”

 

- “Julie isn’t feeling very well today.”

“Oh, isn’t she? What’s wrong with her?”

 

We can also use these short questions of auxiliary phrases to show surprise:

 

- “Diane and Joe are getting married!” 

“Are they? Really?”

 

✅ Use 3:

After some verbs we use so when we don’t want to repeat something. Below are some examples as well as their negative forms:

 

- “Are those people British?”

“I think so.” / “I don’t think so.” = I think they are British.

 

- “Can you watch my dog this weekend?” 

“I suppose so.” “I don’t suppose so.” / “I suppose not.” = I suppose I can watch your dog.

 

- “Will you be home for dinner tonight?”

“I expect so.” / “I don’t expect so.” = I expect I’ll be home for dinner.

 

- “Will Jake be on time tomorrow?” 

“I hope so.” “I hope not.” = I hope Jake will be on time.

 

- “Will it be cold tomorrow?” 

“I’m afraid so.” / “I’m afraid not.”= I’m afraid it will be cold.

 

- “Is it okay if I’m late for work tomorrow?”

 “I guess so.” / “I guess not.” = I guess it’s okay if you’re late.

 

Let’s practice!

 

Complete the sentences with an auxiliary verb. Sometimes the verb must be negative.
