I urgenlty need you to check these sentence. Thank you.

1) I'm emailing you the (required/requested??) information to your school address hoping that your school computer is working now (How do you express tha fact that the computer has broken down?)
2) As I wrote to you in my previous email, I will be pleased to write up the English version of the project but I entirely rely on you and the French school to draw up the content of the project.
3) The idea of making a film out of our scientific experience is particularly interesting and should be included both among the objectives and the results to be achieved by the students.
4) Writeacher, what is your personal opinion about making a film out of our project on biodiversity of water?

1) I'm emailing the requested information to your school address, hoping that your school computer is working now. (How do you express tha fact that the computer has broken down? <~~Slang would be this: ... hoping that your computer-crash has been fixed by now!)

2) As I wrote in my previous email, I will be pleased to write up the English version of the project, but I entirely rely on you and the French school to draw up the content of the project.

3) The idea of making a film out of our scientific experience is particularly interesting and should be included, both among the objectives and the results to be achieved by the students.

4) Writeacher, what is your personal opinion about making a film out of our project on biodiversity of water? <~~Sounds good -- excellent documentation, as well as a way to study the whole project and make improvements for future projects.

1) To express the fact that the computer has broken down, you can rephrase the sentence as follows: "I'm emailing you the required/requested information to your school address, hoping that your school computer is now fixed after experiencing technical difficulties."

To include the mention of the broken computer, you could add a clause such as "after it was repaired" or "once the technical issue is resolved."

2) The sentence seems fine, but if you want to make it clearer, you can rephrase it as: "As I mentioned in my previous email, I would be happy to write up the English version of the project. However, I am depending on you and the French school to provide the content for the project."

3) The sentence appears to be correct and concise. However, you can make it more explicit by adding a comma after "experience": "The idea of making a film out of our scientific experience is particularly interesting and should be included, both among the objectives and the results to be achieved by the students."

4) As Explain Bot, I do not have personal opinions. However, if you are seeking the personal opinion of someone named Writeacher, you can rephrase the question as follows: "Writeacher, what is your personal opinion on the idea of making a film based on our project on biodiversity of water?"
