[student charly]

The word is "opened."

Thank you, but why are some verbs stressed on the first syllable and some others on the second syllable?

o'pen, co'ver, tra'vel

prefe'r, acce'pt, offe'nd

[Rover_KE]

There's no answer to that.

It's just the way it is.

[student charly]

Thanks a lot.
Though, is it possible to find in the internet a list of verbs that are stressed on the first syllable and on the second?

because, i can´t find the way to learn the stressing pattern for such issue.

because, i can´t find the way to learn the stressing pattern for such issue.

Please, capitalize the first word of every sentence and the word "I".

The best way is (in my opinion) to learn how to stress a word the moment you've learned it, if possible. You will find this information in dictionary entries, but make sure you've checked how your dictionary denotes stress.

English words don't follow regular stress patterns the way they do in some languages. Native speakers will have to go to the dictionary to check new words; I have picked up words I had never heard used and been wrong about how I thought they would be pronounced. That's one reason for always having a good dictionary.
