ADVERBIAL CLAUSES OF TIME 
1. Conjunctions in Adverbial Clauses of Time. 
 These clauses broadly answer the question When? and can be introduced by 
the following conjunctions when after as as long as, as soon as, before, by 
the time (that), directly, during the time (that), immediately, the moment 
(that), now (that), once, since, until/till, whenever, and while. We generally 
use a comma when the adverbial clause comes first. 
 e.g. 
 Conj. S + V Conj. S + V 
1. Dad worked as a 
worker 
after 
he had been in the army. 
2. He had washed before he got to school. 
3. By the 
time 
I arrived at the 
airport, 
the plane had left. 
4. You didn’t look very 
well

5. When I came, Nam was sleeping.

his holidays. 
10. We always have to wait till / 
until

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 do 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.
