ッセージを読んで1~3の質問に答えましょう。 Freshers' Week One of the biggest cultural differences between Japanese, American の and British campus life is that in Britain, every campus will have a bar. This surprises many Japanese students, because they can't legally drink alcohol until they are 20. In the U.S., the age limit is usually 21. But in Britain, students can drink from 18. For many British students, their first introduction to student life is “Freshers' Week.” It's a program of events and parties that often involves heavy drinking. Not surprisingly, this can lead to problems for some students, but Freshers' Week parties and the campus bar are an important part of students’ social life.
