In English, the use of tenses like the present perfect and past perfect with certain conjunctions such as ‘when’ can be confusing. In the sentence ‘We had been playing tennis for only 15 minutes when it started to rain heavily,’ there are several things happening that make this construction correct. Let’s break it down and explore why this works.
1. Understanding the Past Perfect Continuous Tense
The sentence uses the past perfect continuous tense, which is formed with ‘had been’ + verb-ing. This tense indicates an action that was ongoing in the past and was interrupted by another event. In this case, the playing of tennis was happening for 15 minutes, and the rain began while this action was still going on.
2. Why ‘When’ is Used in This Context
‘When’ is used to show that one event interrupted or happened at the same time as another event. In this sentence, ‘when’ is connecting the past perfect continuous (‘had been playing’) with the simple past tense (‘started to rain’). The key point here is that the rain didn’t happen first; it interrupted an ongoing action, which is why this sentence construction is correct.
3. The Role of the Simple Past in the Sentence
In the second part of the sentence, ‘it started to rain heavily,’ we see the simple past tense. This is used because the rain is a single event that happened after the ongoing activity of playing tennis. When the two tenses are used together, it shows that the rain interrupted the continuous action of playing tennis, making the structure grammatically correct.
4. Common Misunderstandings of ‘Have’ and ‘Had’
Many learners of English are confused about when to use ‘have’ or ‘had’ in sentences with ‘when.’ Generally, ‘have’ is used in the present perfect tense for actions that are completed in the recent past, while ‘had’ is used in the past perfect tense to indicate an action that was completed before another event in the past. In this case, ‘had been playing’ is used because it refers to an ongoing action that was interrupted.
5. Conclusion
The sentence ‘We had been playing tennis for only 15 minutes when it started to rain heavily’ is grammatically correct because it follows the rules of the past perfect continuous and the simple past tenses. The use of ‘when’ is appropriate here as it shows that one event (the rain) interrupted another event (the tennis playing). Understanding these tense rules can help clarify when to use such constructions in English.
