I urgently need you to check these sentences.

1) Our German partner wrote that students can communicate in one of the European languages of their partners. I'm really disappointed by his words and I need to reply to this.

2) Among the linguistic objectives you included:
- enabling students to explain, interpret, exchange and finally compare the results of their experiments in English and other European languages, both in written and oral form.

3) We once agreed that English should be used as lingua franca both to exchange information and write reports.
English should be used for two main reasons. First,our participating students, who belong to the branch of applied sciences, don't learn either French or German and therefore won't benefit at all from the partnership.
3) Our science teachers will have to teach science in English in two years' time in the last year of high school.
4) I think you should distinguish our Comenius project, which must be carried out in English, from the student exchange programme, in which there is no official language and therefore students can make themselves understood in the language they want.

English should be used for two main reasons: First, our participating students, who belong to the branch of applied sciences, don't learn either French or German, and therefore won't benefit at all from the partnership if there is such a stipulation as you have written.

3) Our science teachers will have to teach two years' worth of science in English in the last single year of high school.

4) I think you should distinguish our Comenius project, which must be carried out in English, from the student exchange programme, in which there is no official language and therefore students can make themselves understood in the language they want.

1) Here's how you can check the sentences:

- Read each sentence carefully and make sure that the ideas are expressed clearly.
- Check for any grammar or spelling errors. Pay attention to the verb tenses, subject-verb agreement, and punctuation.
- Make sure that the sentences are coherent and convey the intended meaning.
- Consider the overall tone and appropriateness of the language used.
- Ask yourself if the sentences effectively convey your disappointment and your intended reply.

2) To check the second sentence, use the same process as mentioned above. Focus on the linguistic objectives listed and ensure that they are clear and accurately stated. Check for any grammar or spelling mistakes.

3) Let's check the third sentence:

- Read the sentence and make sure it is grammatically correct.
- Check if the reasons given for using English as the main language are logical and consistent with the goals of the project.
- Consider the appropriateness of the language used to express your thoughts.
- Make sure the sentence conveys the message that English is the best option for the project because the participating students do not learn French or German, and their education won't benefit from those languages.

4) For the fourth sentence, follow a similar process as mentioned above:

- Read the sentence carefully and check for any grammatical errors.
- Consider the logic and clarity of the distinction being made between the Comenius project (which must be carried out in English) and the student exchange program (where there is no official language).
- Evaluate the appropriateness of the language used to express your thoughts.
- Make sure the sentence effectively conveys your opinion and the intended contrast between the two programs.
