雅思口语P3 Is it important to know the culture and language before going to another country

I think that it could be very important to those who are willing to study and work in other countries for years. I mean, two reasons. No.1, the language is the basic, if you want to do well in your work and study, the language is the most important thing that you have to learn well. Like English, Spanish for example. No.2, the culture, which in my consideration, include eating habit, the way we speak and behave, the festivals you know. All of these can be equally important to us. Before traveling to another country, we should try to get ready for it. So, I think that it seems very very very necessary to have a deep insight into the culture and language before going to another region of the world. That is it.
