Adverbs of Time and Duration provide essential details about when and for how long actions occur. Mastering their use enhances sentence clarity and precision, particularly at the B2 level, where nuanced expression is key.
Examples
Example 1
IncorrectShe will arrive at the airport yesterday.
BetterShe arrived at the airport yesterday.
'Yesterday' indicates a past action, so the verb must be in the past tense.
Example 2
IncorrectThey have been studying since two hours.
BetterThey have been studying for two hours.
'For' is used with durations, while 'since' is used with specific starting points.
How It Works
Meaning
Adverbs of time and duration specify when an action occurs and for how long it lasts. They enhance clarity by answering 'when?' and 'for how long?', crucial for nuanced expression at the B2 level.
Common adverbs include 'yesterday', 'tomorrow', 'for two hours', and 'since Monday'.
Use it when
- Indicating a specific time, such as 'yesterday' or 'next week'.
- Describing duration, like 'for three hours' or 'since last year'.
- Sequencing events, using phrases like 'before lunch' or 'after the meeting'.
- In formal writing to ensure precise timing and duration.
