Hi there, what's the difference between I have looked everywhere for my cat but I can't find it VS I looked everywhere for my cat but I can't find it. I can't see the point of using perfect tense to the example like this: William the conqueror conquered England VS William the conqueror has conquered England.

In the question section of the video there is the sentence 'she has played the piano for 10 years'. Why is it has played and not has been playing?

This was a very good lesson, and I understand. My question has to do with alternative wording. I am referring to the last example in each of the last two exercises. Can the sentences be rewritten as follows?:

1. By tomorrow night the judges will have already announced the winner. (The position of 'already' bothered me.)

2. We drove a thousand miles to see you. (Is this only used as colloquial?)

if a verb in the perfect tense describes an action that has already been completed as of the time being discussed, then why is the present perfect tense = an action that began in the past and are still occurring in the present?

Great lesture but I have one question. The second example had run, Why not had ran?

Perfect Tenses

  • A verb in a perfect tense describes an action that has already been completed as of the time being discussed.
  • Perfect tenses are formed by adding some of the helping form to have (and, in the case of the future perfect tense, will) to the past participle form of a verb.
  • To form the present perfect tense, add have or has, as appropriate, to the past participle form of a verb. Use the present perfect tense to describe actions that began in the past and are still occurring in the present, and actions that began in the past and were completed at an unspecified time.
  • To form the past perfect tense, add had to the past participle form of a verb. Use the past perfect for actions already completed before another point in time or action.
  • Form the future perfect tense by adding will have to the past participle form of the verb. Use the perfect tense for actions that will be completed before or by a specific time.
