Negative: Past simple Vs Present perfect Use
In British English, the use of Simple Past and Present Perfect is quite strict. As soon as a time expression in the past is given, you have to use Simple Past. If there are no signal words, you must decide if we just talk about an action in the past or if its consequence in the present is important.
Note that the following explanations and exercises refer to British English only. In American English, you can normally use Simple Past instead of Present Perfect. We cannot accept this in our exercises, however, as this would lead to confusions amongst those who have to learn the differences. Certain time in the past or just / already / yet? Do you want to express that an action happened at a certain time in the past (even if it was just a few seconds ago) or that an action has just / already / not yet happened? Simple Past certain time in the past Example: I phoned Mary 2 minutes ago. Present Perfect Simple just / already / not yet Example: I have just phoned Mary.
