I left out a sentence. I don't know which form is best.
1)I would be really grateful to you if you could send me the names of Irish high schools which might be interested in a partnership with our school.
2) It doesn't matter if German is not taught at their school.
3) (It would be nice of you if you could send me ...... Is it correct??)
1 and 2 - OK
3. Too wordy. Try this: Please send me...
All of the sentences you provided have slightly different meanings, so it depends on what you want to convey in your message. Here's a breakdown of each sentence and their potential implications:
1) "I would be really grateful to you if you could send me the names of Irish high schools which might be interested in a partnership with our school."
This sentence indicates that you are requesting the recipient to provide the names of Irish high schools that could potentially be interested in partnering with your school. It shows that you would greatly appreciate their assistance in this matter.
2) "It doesn't matter if German is not taught at their school."
This sentence suggests that you are stating a condition for the potential partnership. You're letting the recipient know that it is not a requirement for the Irish high schools to offer German language courses. This implies that your school is open to partnerships even if the partner school does not teach German.
3) "(It would be nice of you if you could send me ...... Is it correct??)"
This sentence seems unfinished, and it appears you are seeking clarification on its correctness. To make it grammatically correct and meaningful, you could say, "It would be nice if you could send me..." By phrasing it this way, you are expressing a polite request or suggestion without explicitly mentioning gratitude.
Ultimately, the best form depends on your intentions and the tone you want to convey. Consider the purpose of your message and choose the sentence that aligns with your goals.
