Passage Three
Most students choose “Homestay” accommodation when they study abroad：others select Homestay even if they are not on a study visit.Statistics show that it’s a form of accommodation gaining in popularity all the time.
But what is Homestay? And what makes it so popular?
Homestay means living with a family，or“host family”as we say.There are three ways of doing it：choose to learn English in a language school near to your Homestay location：
have your English classes in the house with a member of the family who is a qualified teacher;
select not to have classes at all when you visit——a popular choice if you want to do the tourist thing for example.
Even in their busy summer period the organizations that arrange the Homestays will always try to place you with the most suitable host family to match your requirements.Placement(安置)organizations think about location，interests，language level，eating requirements，allergies (过敏)and other requests you may have.
Though prices vary according to your needs，good quality Homestay accommodation can be relatively economical--and although you may be charged an extra amount of money if you want your Homestay in or near the city center.Even if you stay further out，you can expect your journey into the center not to exceed 30 minutes.
Not only does Homestay accommodation represent value for money， it also gives you an excellent opportunity to practice English with your host family.This is a very important extra for students who like to speak as much English as possible. But if you plan to learn English，why not have your English classes in your host family. There’s no better way to learn English than this—the perfect combination of learning and accommodation combined with the cultural experience !
