Презентація "Future Time Clauses"

Future time clauses

Time clauses show that an event will happen at a certain time. Time clauses are preceded by adverbs or adverb phrases when, before, after, as soon as, until which show that they represent a time.

The verb after the adverb or adverb phrase is Present Simple (even though the action will happen in the future) - Tom will turn off the lights when he leaves the office. (NOT when he will leave). Tom will turn off the lights - is the main clause and we use the Future Simple; when he leaves the office - is the time clause and we use the Present Simple.

examples: - Dad will reply to the letter when he comes home from work. (NOT when he will come home). - I will tidy the living room before I go to bed. (NOT before I will go to bed). - They will do the shopping before we arrive. (NOT before we will arrive). - She will go running after it stops raining. (NOT after it will stop raining). - Alex will write a review after he finishes reading the book. (NOT after he will finish reading the book). - I will not go home until I finish the report. (NOT until I will finish the report). - The nurse will wait until the ambulance arrives. (NOT until the ambulance will arrive). - Jane will call her mother as soon as she arrives at the airport. (NOT as soon as she will arrive at the airport). - The operation will begin as soon as the patient is ready. (NOT as soon as the patient will be ready).

after, as soon as, when, until 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. - When I finish my homework, I’ll go to bed. - Until I finish my homework, I’ll not go to bed. (The earlier action is I finish my homework; the later action is I’ll go to bed).

before for the later action - Before I go to bed, I’ll finish my homework. - I will tidy the living room before I go to bed. - They will do the shopping before we arrive.

time clause at the beginning or at the end of the sentence After I finish my homework, I’ll go to bed. OR I’ll go to bed after I finish my homework. As soon as I finish my homework, I’ll go to bed. OR I’ll go to bed as soon as I finish my homework.(The only difference is we use a comma if the time clause is at the beginning of the sentence).
