[Grammar] has taken, was taken

[Oceanlike]

I read in a book: the present perfect tense of a verb is formed when the past participle of the verb follows 'has' or 'have'.

For example, He has taken the book.


If I were to use another primary verb, such as "is" (which I understand to be under the 'Be' group of verb), and combine it with "taken", as in the following example, is the sentence also in the present perfect tense?
Eg: He is taken to .............

Thank you for the teaching! :-D

I think 'He has been taken into custody' is in the present perfect, but I am not a teacher.

No, you cannot use "be" (in any of its forms) in lieu of "have" or "has" in forming the present perfect!

@teechar, this means that the present perfect tense is formed only when the past participle of the verb follows 'has' or 'have'?

Thanks!

@Matthew, 'he is taken......" is not 'proper' English right? lol :-D

I'm just wondering if 'subject + is + past participle' can be used at all.

Thanks!

I think the following is proper English, but I am not a teacher.
'I will bail him out as soon as he is taken into custody.'

Oceanlike, you're talking about two different things, the present perfect tense and the passive voice!

My answer in post #2 was in response to your question in post #1, not to Matthew's post #2.
:shock:

Simple tenses:
"He is taken" is the passive voice of the simple present tense.
"He was taken" - passive of the simple past tense (imperfect).
"He will be taken" - passive of future tense.

Perfect Tenses:
"He has been taken" - passive of the present perfect.
"He had been taken" - passive of past perfect.
"He will have been taken" - passive of future perfect.
