Question
Work in pairs and discuss. What tense and aspect is used in each sentence? What is the difference in meaning, if any, between the sentences in each pair?
Answer
1
- a) present perfect simple; b) present continuous
- No significant difference in meaning.
2
- a) future perfect continuous; b) future perfect simple
- These can be essentially the same in meaning if finished one way, e.g. '... here for 5 years', though even then a) might express a temporary view of 'living here'; b) can be completed in ways that a) can't, e.g. '... in fifteen countries in my life thus far'
3
- a) future perfect simple; b) future continuous
- No significant difference in meaning.
4
- a) past perfect continuous; b) present perfect continuous
- The point of reference is different. In sentence a) it is before and up to a point in the past. In sentence b) it is before and up to now. So, in a) the person is talking about a 'finished' story from their life, in b) a current, unfinished story.
5
- a) past continuous; b) past perfect simple
- Essentially no significant difference in meaning - the 'but' implies a change in plans for both, and either could come from a 'narrative' of someone's life when talking about a change of plans in the present OR in the past.
