Grammar: Past Simple v Present Perfect

 

Study these examples from It's my job. Why is the Past Simple used for sentences 1-3 and the Present Perfect for sentences 4-6?

1 I was in the army for four years.

2 I joined when I left school.

3 I travelled quite a lot.

4 I've been with the company for eight years.

5 I’ve been to Norway, Kenya, and Belize.

6 I've seen quite a few changes in phone systems.

 

• We use the Past Simple for things that happened at a particular time in the past or during a period that ended in the past:

I travelled a lot when I was in the army.

• We use the Present Perfect to talk about past experiences but not when they happened:

I've been to the USA.

• We use the Present Perfect for actions which happened during a period from the past to the present:

He’s worked as a technician for eight years. (He’s still a technician.)

• We often start a topic using the Present Perfect and then switch to the Past Simple:

A Have you ever been to Norway?

В Yes, I went there in 2001.

 

Ex. 1. Complete the text about developments in radio and television. Put the verbs in brackets in the correct form: Past Simple or Present Perfect.
