In my opinion, it is very important to learn foreign languages.
Firstly, learning foreign languages helps us in daily life. At least one foreign language increases our vocabulary and helps us with exams and theses.
Secondly, it is very good to study several foreign languages. Some peoples, like the French people, refuse to learn other languages. That's why when we go on holiday it's good to let us know.
In conclusion, studying multiple languages helps to increase vocabulary.
