Past tense review

We use simple past to talk about complete finished actions. It is often used in stories.

e.g. I wrote my exams yesterday.

You make simple past negatives by...

did not/ didn't + infinitive (the verb without "to").

​

He cleaned the car --> He did not clean the car. (NOT He did not cleaned the car).

She saw you. --> She didn't see you. (NOT She didn't saw you).​

To make a question in simple past...

1. Did+ subject+ infinitive (verb without "to")

• ​You heard me. --> Did you hear me? (NOT Did you heard me)

• He learned Spanish. --> What did he learn? (NOT What did he learned?)​

​2. When "who" and "what" are subjects, make questions without "did"

• Sue phoned --> Who phoned? (NOT Who did phone?)

• Something nice happened --> What happened? (NOT What did happen?)

are verbs that can't be turned into past tenses just by adding -ed. Some examples include

• go --> went

• see --> saw

• buy --> bought

• pay --> paid​

Simple past

Show actions that are completed prior the moment of focus.

There are four types of perfect tenses, but today, we're focusing on the present perfect (which is used to describe the past! Confusing, I know)

Put have/ has with the past participle

• Regular verb's past participle ends in -ed, like in simple past tense.

  • e.g. I have worked.

• ​Irregular verb's past participle is often different from the ​simple past tense.

  • e.g. I have seen. She has spoken. We have gone. You have bought.​

Some text here about the topic of discussion

• Use present perfect when you're thinking about the past and present together.​

• e.g. I've written to Tom, so he knows what's happening. (I wrote to Tom in the past, and the information helps him in the present.)​

• Use simple past when you're thinking ONLY about the past.​​

• e.g. I made a cake for the kids, but they didn't like it. (I'm not talking about the present.)
