2 Tenses in Adverbial Clauses of Time: 'no future after temporals' When the time clause refers to the future, we normally use the simple present after after, as soon as, before, by the time, directly, immediately, or
we use the present perfect where we might expect the future perfect These two tenses are often interchangeable after temporal conjunctions
- The Greens will move to a new flat when their baby is born (or has been
born)
The present perfect is often used after once and now that:
- Once (= when) we have decorated the house, we can move in
- Now that we have decorated the house, (action completed) we can move in
3 Will' after when'
Though we not normally use the future in time clauses will can be used after when in noun clauses
- The hotel receptionist wants to know when we will be checking out
tomorrow morning
When meaning 'and then' can be followed by present or future:
- I shall be on holiday till the end of September when I return (or when I
shall return) to London
