An example is 'I had finished my homework'
past form is only a main verb but in the past, example i walked. past perfect is when you use had+past participle of a main verb,example i had walked.
To make the past perfect tense: Subject + Had + Past Participle For example: I had finished my homework.
Past perfect - I had finished my homework. Present perfect - She has finished her homework. Future perfect - I will have finished my homework.
The past perfect tense is formed like so:Subject + Had + Past Participle.So, for example, the past perfect tense of "blow" would be:I had blown.
You + Have + Past Participle. For example: You have eaten.
Using the verb 'do': Simple past tense: did Present perfect tense: I/You/We/They have done. He/She/It has done.
The train had left when I arrived at the station. had left arrived
Yes that's correct. Subject + Had + Past Participle For example: I had danced.
Present continuous: He is driving. Past continuous: He was driving. Future continuous: He will be driving. Present perfect continuous: He has been driving. Past perfect continuous: He had been driving. Future perfect continuous: He will have been driving.
The present perfect is formed with has/have + past participle of any verb.I have + past participleWe have + past participleYou have + past participleHe/she/it has + past participleThey have + past participleI have traveled to Florida many times.She has eaten already.David has worked as an electrician for fifteen years.The present perfect is used to talk about actions in the past that happened at an indefinite time. It doesn't matter when it happened (my first example). It is also used to express actions that happened in the past but have an effect on the present (my second example). My third example shows that an action started in the past is still continuing in the present.
