Pengertian Time Clause


            Time clauses are used in English to demonstrate a period of time based on an action or event, similar to dependent clauses in conditional sentences. For example, I will cook dinner when I get home. ‘When I get home’ is a clause demonstrating a point in time, based on an action/event (the time that I get home), replacing a simpler time such as I will cook dinner at 7pm. Time clauses are complete ideas that require subjects, verbs and objects, but they do not always use the same verb rules as the main clause.

A. Know Your Time Clause Connectors
            Here is a  list of Time Clause Connectors with some examples and meanings. Some Time Clause connectors have similar meanings and can be used interchangeably. However, it is important to note the small differences in meaning between the various Time Clause Connectors.
1.             After I finished playing baseball, I had ice cream with the team.      (After means the moment after something happens)
2.             I will finish my homework before I go to the party.      (Before means before the moment)
3.             When the birthday boy arrives, everyone scream surprise!        (When means the moment something happens)
4.             I like to read books while I listen to jazz music.     (While means a period of that time)
5.             Since I was a young boy, I have always loved the beach.    (Since means starting at a specific time)
6.             I will call you as soon as my plane lands.     (As soon as means when something happens immediately)
7.             I will wait until you finish talking.      (Until means something finishes at that time)
8.             By the time he arrived, she was already gone.     (By the time means one event is completely finished when the other event happens)
9.             Once everyone has sat down, we can begin eating. (Once means something happens when something else is completed.)
10.         As he read the names on the list, he began to cry. (As means a period of time)
·         Note: As and while have the same meaning.  By the  time and once have similar meanings. When and as soon as also have similar meanings.
B. Time Clause Verbs
In most cases, time clauses use the present tense while the independent clause uses thefuture or present. Never use the future tense in a Time Clause!
·           When my Dad gets home, we eat dinner.
·           After I practice playing soccer, I will take a nap.
Sometimes Time Clauses refer to the past. In this case, use the simple past or past perfectwith the time clause. Note the independent clause also is in the past tense.
·           We started the test as soon as the teacher (had) arrived.
With Since Time Clauses the present perfect or present perfect progressive is used in the main clause.
·           have worked at this school since 2004.
·           have been playing golf since I was a little boy.
With While and As Time Clauses the present progressive tense is often used.
·           She likes to drink wine while she is cooking.
·           As I was riding my bicycle, I noticed a new ice cream shop.
C. Reduced Time Clauses
Time Clauses are often shortened by cutting the subject and the “be” verb.  If the time clause does not contain a “be” verb, add “ing”.
·       She likes to drink wine while she is cooking.
·       She likes to drink wine while cooking.(reduced)
·       I like to read books while I listen to jazz music.
·       I like to read books when  listening to jazz music. (reduced)

Be careful! Not all Time Clauses reduce.
