Writeacher, I urgently need you to check these sentences.

1) I'm pleased to read that English is and will remain the lingua franca of the project. For this reason, we'd like to vary a few sentences in your application form. In particular, this sentence:
2) "By executing the whole cycle of project management in English and the two other partner languages, the pupils will have a fairly better qualification to present in their portfolio".
I will omit the two other partner languages because our students will not carry out any part of the project either in German or French.
3) They will certainly have the opportunity to get to know other European languages and therefore this project can spur them to learn the language of their partners.
4) I will email Prof. .... and let him know about your new requests.
5) Being an English teacher, I think I'll have to revise any mistake I come across while reading the application. Though I'm on sick leave, I'll do my best to check everything by tomorrow.

5) OK

Question for you. I'm in Central Time in the US. It's now 6:13 am for me. I think you are about 6 or 7 hours ahead of me, right? Is it 12:13 or 1:13 pm where you are?

Here are my suggestions for the sentences:

1) I'm pleased to read that English is and will remain the lingua franca of the project. Due to this, we would like to make a few changes to your application form. Specifically, we would like to modify this sentence:

Original: "By executing the whole cycle of project management in English and the two other partner languages, the pupils will have a fairly better qualification to present in their portfolio."

Modified: "By executing the entire project management cycle in English, the pupils will have a stronger qualification to include in their portfolio."

2) I will omit the two other partner languages in the sentence because our students will not be involved in any part of the project in German or French.

3) They will certainly have the opportunity to learn other European languages, which can encourage them to learn the language of their project partners.

4) I will send an email to Prof. .... to inform him about your new requests.

5) As an English teacher, I believe it is my responsibility to review any mistakes in the application. Even though I am on sick leave, I will do my best to check everything by tomorrow.
