I like that, very much, thank you

hi team its realy very helpful.
now i feel that i am getting command over verbs.
actually we had a bit confusion regarding  irregular verb that is there any gramatical rule for irregular verb?

Hi,
I'm glad to hear that you are making progress!
I'm afraid there aren't really reliable rules for irregular verbs - that's what 'irregular' means! One rule is that the more common the verb, the more likely it is to be irregular.
However, if you look at a list of irregular verbs, you will see that you can see some groups. For example, 'break / broke / broken' and 'speak / spoke / spoken' obviously follow the same pattern. 'Choose / chose / chosen' is not exactly the same, but is quite similar. These sort of patterns can help you to learn them.

One problem also, when I write I do not feel confident about my sentence and vocabulary. Please help me and give me some tips so that I can improve my writing skill and improve my spelling mistakes.

Hello The LearnEnglish Team!
I was wondering why, in the 6th question of the third test, is just "has" the auxiliary verb and not the both "has" and "been"?
Thank you
