It is interesting to visit another country,but sometimes there are problems when we don't know the language very well.It may be hard to speak to the people there.We may not know how to buy things we need.In the western country,we may not know where to have meals and what to order in a restaurant.When we need help,we may not know how to ask for help.It's not pleasant to meet with such problems.So we must study English well.
