A speech for Leaving Foreign Students

How time flies! When I *looked back to at the two weeks we’ve spent together, I feel *felt it was a happy, unforgettable experience.
What impresses me most is that you helped us learn English. When my ^classmates asked you some questions to you about English, you could always give ^them a perfect explanations. We really improved our English. Besides learning, we also did some sports together. I will never forget your great football skills when we played football with you. These things and other activities we’ve done together are #our good memories forever. #between us If possible, please come to our school again next year.
I’m looking froward forward to meeting you again and ^^wish you a good journey.                                                                        

Thank you.

Hi there,

Just some suggestions for your writing:

*You are describing a specific moment in the past when you remembered (looked back at) the two weeks you have spent with some foreign friends, so you "felt" (past tense) happy at that moment in the past. 

^ More than one classmate posed some **questions, so your foreign friends gave your classmates (them) perfect ** explanations.

# Collectively (between us), you all have good memories. You can use the possessive pronoun (our) to describe your good memories. 

^^ Upon closer scrutiny, this sentence doesn't make sense. As you used the coordinating conjunction (and), it means that you are looking forward to two things together: (1) meeting your friends again (they have to come to your country for this to happen) (2) wishing them a good journey (this happens when they are leaving your country). Perhaps you can edit your sentence: I'm looking forward to meeting you again and I wish you a safe journey home."

I hope this helps. 

When I look back at the two weeks we’ve spent together, I feel it was a happy, unforgettable experience. 

Just like "feel", the verb "look" should be in the present tense.

The phrasal verb "look back at" is used when talking about memories of the past. "Look to" has a different meaning, for example: "we look to the future with hope", "we look to you for help".

It is not incorrect to say "asked some questions to you", but it's much more common to say "asked you some questions".

I will never forget your great football skills when we played football with you.

This is grammatically correct, but stylistically, it is not recommended to repeat the word "football" twice so close together in the same sentence.

If possible, please come to our school again next year.

This sentence is correct, but it sounds more natural if you add the word "again".

I’m looking forward to meeting you again and wish you a good journey.
