Hello teachers, I have a question here.
I came across this phrase in a news report and I hope you can help me with it.
"It was the worst disaster that the city <has suffered> for over 50 decades"
My question is why "has" is used instead of had?
I thought when one uses 'past tense' in this case is "was" he'll have to use past participle?
Perhaps you can explain to me?
It's actually present tense but referring to the past.
