This document discusses the use of future time clauses to describe two future events. It notes that future time clauses begin with words like "after", "as soon as", "once", or "when", with the verb following the time word in the simple present tense. It provides examples like "After I finish my homework, I'll go to bed". The document also discusses using the present perfect and words like "before", "until", and "while" to link future events and the placement of the time clause within the sentence.

1. Future Time Clauses

Intermediate Grammar

2. • When we talk about two events in the future,
we can use one sentence with a future time
clause.
• A future time clause may begin with after, as
soon as, once, or when.
• These time words come before the earlier
action.

• After I finish my homework, I’ll go to bed.
• As soon as I finish my homework, I’ll go to bed.
• Once I finish my homework, I’ll go to bed.
• When I finish my homework, I’ll go to bed.
What do you notice about
the verbs in these sentences?

5. • After I finish my homework, I’ll go to bed.
• As soon as I finish my homework, I’ll go to bed.
• Once I finish my homework, I’ll go to bed.
• When I finish my homework, I’ll go to bed.
The verb after the time word is
simple present (even though it will
happen in the future).

Before is another time word. It
comes before the later action.
Before I go to bed, I’ll finish my homework.
I’ll finish my homework before I go to bed.

7. Until is another time word. It comes before the earlier
action if that action will continue up to the second
action.

• Until I go to bed, I’ll do homework.

8. We can put the time clause at the beginning or end of the
sentence.
• After I finish my homework,I’ll go to bed.
• I’ll go to bed after I finish my homework.
• As soon as I finish my homework,I’ll go to bed.
• I’ll go to bed as soon as I finish my homework.
If it’s at the beginning, use a comma to make your sentence
easier to read. (If it’s at the end, you don’t need a comma.)

9. In any of these sentences, you can use present perfect
after the time word.
It emphasizes that the action will be completed.
• Once I have finished my homework, I’ll go to bed.
• I’ll go to bed when I have finished my homework.
(This is less common than simple present.)

10. Use when or while if two future events will
happen at the same time.
• While my roommate sleeps, I’ll be doing my homework.
• When my roommate sleeps, I’ll be doing my homework.

Because the two events will happen at the same time, the
order of clauses doesn’t matter.
• While my roommate sleeps, I’ll be doing my homework.
• My roommate will be sleeping while I do my homework.
Just remember: the verb after the time word should be
simple present.
