Traveling
Travelling to other countries is amazing. It's possible to learn about (1) new cultures, exotic food, different languages, wonderful landscapes, and more. But it presents some challenges such as, the airplane leaving (2) you or arriving late, lost luggage or documents, maybe not understanding what people say when you ask for directions leaving you are lost in a big city.
So, try to be careful with your time and bags, learn some (3) phrases and words in the native language of the country you are visiting, and enjoy it.
1) Sé que el verbo es conocer en español, pero en inglés "aprendimos de una cosa" en vez de "conocer una cosa"
2) "taking off without you" es mejor pero intenté mantener tus palabras todo lo posible
3) "several" me parece más natural aquí pero "some" está bien
