अनुबाद - चिनीया (सरल)-अंग्रेजी - 早知道会在这种情况下用英语的话，以前就好好学了

Hi Oana, thx for your translation. My wife tells me it's maybe not the good meaning. What about moving the "If" at the begining of the sentence, like this : "If I knew from the begining that I would have had to use English in that situation, I would have learnt it better."

You may be right. I would transform the phrase like this: "If I knew from the beginning that I had had to use English in that situation, I would have learnt it better". I think the use of "would" in the first part of the phrase is not grammatically correct. Thank you for your suggestion.

If I knew I should use English in this situation, I would have learnt it better.

is OK.

I think a simple past sense is already understandable.

but you missed "的话"

...的话 is a form of supposition.
The complete form is 如果...的话, here it uses only the latter part.

Yes, the
的话
means "if"...

and maybe we could say
If I had known earlier...
instead of
If I knew from the beginning...

and finally
...I would have studied it harder.

Anyway, another good translation!

Thank you, Ian, you are very precious

And you understand Chinese very well!

Of course I know 如果...的话, it's basic Chinese, there was a misunderstanding there.
Have a nice day, Pluiepoco and Ian!
