Some athletes have taken drug tests to prove they are not on steroids.
"have taken" is correct
It should be: 'Some athletes took drug tests to proove they were not on steroids'
What is your question ????In this sentence take is an irregular verb
The first is almost correct. It should be, "Some athletes have taken drug tests to prove they are not on steroids." That is, "have taken" is the correct form, but it should also be "drug tests" rather than "drugs tests". "Have taken" is the correct form because "have" is the plural form, and "athletes" is plural. The singular form is "has taken", so it would be correct to say "One athlete has taken drug tests to prove he is not on steroids." Always use the past participle "taken" and not the simple past tense "took" in forms that use a form of the auxiliary verb "have": have taken, had taken, has taken, would have taken, and so on.
"Taken" is an irregular verb, "Take, took, taken." If it were regular it would be "Take, taked, taked".
Taken is an irregular verb. Taken is the past participle of the verb 'take'. If the verb was regular, then the past tense of 'take' would be 'taked' whereas instead it's took and taken.
