Welcome to English grammar spot, this lesson is about the difference between
-
the past simple and the present perfect.
-
I am going to show you when to use a past simple and when to use a present perfect
-
and more important how to keep them apart.
-
Take a look at these sentences:
-
I broke my leg on holiday last year.
-
I have broken my leg.
-
The first sentence is in the past simple tense, the second sentence is in the
-
present perfect tense
-
First we are going to take a look at how to form a past simple
-
and how to form a present perfect.
-
For the regular verbs we take the infinitive form of the verb and add '-ed' for the past simple.
-
For example
-
I kicked the ball.
-
For the irregular verbs:
-
we use the unique past simple form.
-
For instance She bought a bike.
-
For the present perfect we use the auxiliary verb 'to have' and the past participle.
-
For the regular verbs we make a past participle by adding '-ed' to the verb.
-
For example I have kicked the ball.
-
For the irregular verbs the present perfect also uses the past participle
-
but this past participle has a unique past perfect form.
-
She has bought a bike.
-
Now let's have a look at when we use a past simple.
-
We use a past simple when something happened at a specific time
-
in the past.
-
I broke my leg last week.
-
So it's important that I tell you that it was last week.
-
For the present perfect time is not important
-
I have broken my leg. It's not important when it happened.
-
We also use a present perfect for things that started in the past but have
-
continued in the present.
-
For example: I have lived here since 2012.
-
In the past simple that would be: I lived there in 2012.
-
Meaning I no longer live there.
