Form
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?
Certain event in the
past or how often so far?
Do you want to express when a certain action took place or
whether / how often an action has happened till now?
Do you just want to express what happened in the past? Or do
you want to emphasise the result (a past action's consequence in the present)?
