TOPIC: Verb tense: time expressions
Sometimes you may have difficulty to determine the correct verb tense in a sentence.
What you can do is try to identify the time expression in the sentence (that is any word or
phrase that tells you when it happened. For example: last week, ten years ago, by the
time the meeting started, etc.) These expressions of time are linked to specific verb
tenses. So, based on which time expression you see in the sentence, you will know which
is the correct tense for the verb.
Time expressions will help you to recognize verb tenses
