"Though" is a preposition and you never end a sentence with a preposition. You could use it at the beginning of the second phrase: "...quickly, though other things..." Prepositions are often used to join two thoughts. Hope that helps. J'apprends français aussi.

Script for a ZEEMEE VIDEO

Hi everybody,
I wrote a script of presentation for my college application. Thank you for your corrections and comments !

"I love to practice languages. Practicing a language is just a simple way to understand others, their cultures, and their way of life. I have online correspondants and friends from all around the world, that have made me more open-minded.
I'm fond of traveling, especially in the United States. My dream is to work in international communication in the US or in another English speaking country. Before I knew about the BBA Global Business offer, I was thinking about starting my  first year of college in France and then leaving to study at   a university abroad. The BBA Global Business matches exactly with my desire, and permits  students to have an early international experience at a university abroad.
As we discover the continents, we learn to know different countries, cultures and people. This is exactly what I am looking for.

To conclude, I would say that language and travel are very important to me. My visit to the United states was a beautiful and tremendous experience, and from that moment, two years ago, I knew exactly who I wanted to be, what I wanted to do and where I wanted to live. My travels in the US changed me and helped to define my goals. My passions are dancing and reading classic and fantastic books.

Thanks you for watching my ZEEMEE MEET ME VIDEO, I really hope you enjoy it and hope that now you know better who I am and who I want to be in the future. Kinds regards !"

Here are a few suggestions. I may have changed your meaning so please correct it as you desire. Also note that some words are deleted or changed and not highlighted in yellow.

It is a word that is not used very often in common conversation. I think the origin is from the Victorian era in England where people were expected to be very proper. So it does refer to more than just sex but that is often what people think when they hear/use the word prude or prudish. Hope that helps.

my letter to a restuarant manager

Hi there, Could you please review my letter to a manager, thank you!
============================================
Dear Sir or Madam,

I'm writing to thank you for your great restaurant service. We celebrated our graduation with some classmates the evening of  December 28th, 2016. My friends recommended your establishment based on the 5 star ratings. The private rooms were great for conversation and we enjoyed the entertainment. 

I reworded several of the sentences and may have changed the meaning you were trying to convey.
