Phrasal verbs and do, does, and did

Phrasal verbs and do, does, and did

Like ordinary verbs, phrasal verbs form negatives and questions with do, does, and did.

Present tense questions

In the present tense, questions are formed with do (except when the subject is he, she, it, or the name of one person or thing):

Why do I always fall for losers?

Do you sometimes doze off in class?

Do we ever give in to pressure?

How do these bottle tops come off?


When the subject is he, she, it, or the name of one person or thing, 

does is used. Remember that the -s form of the verb is not used in 

questions:

Does this welding torch throw sparks up into the air?




Present tense negatives

In the present tense, negatives are formed with do not or don't 

(except when the subject is he, she, it, or the name of one person or 

thing):

I used to doze off while driving, but I don't anymore.

I think he has the flu because you don't usually throw up when you

have a cold.

We don't usually fall for crazy stories like that.

If his dogs do not stay off our lawn, I'm going to call the dogcatcher.


When the subject is he, she, it, or the name of one person or thing, 

does not or doesn't is used. Remember that the -s form of the verb is not used in negatives:

If Mark doesn't pull through, five children will be without a father.


Past tense questions

In the past tense, questions are formed with did. Remember to use 

the infinitive form of the verb:


I'm so embarrassed. Why did I fall for his lies?

Did the patient pull through?

How many times did he throw up?

Did we give in to their demands?

Did they hear about the explorer who was eaten by piranhas?



Past tense negatives

In the past tense, negatives are formed with did not or didn't. 

Remember to use the infinitive form of the verb:


I was really sick, but I didn't throw up.

You didn't fall for that nonsense, I hope.

He pulled and pulled, but the bowling ball did not come off.

We didn't hear about the half-price sale until it was too late.I'm sorry.

Present continuous tense versus present simple tense

Kyle wants to work in China, so he’ s learning Chinese. The temperature of the world is increasing very fast. Present Simple (Subject + do/does) - We use the simple for things in general or things that happen repeatedly. For example, I do my homework every day. Water boils at a 100 degrees Celsius.
