VII. Read the text and then answer the questions. Schools in Britain Schools in Britain are a little different from schools in Vietnam. Most schools have a five-day school week, from Monday to Friday. The school day begins at around 9 a.m. and ends at around 3 p.m. for the youngest children and 4 p.m for the older ones. There is a break of 15 or 20 minutes in the morning and sometimes also in the afternoon. Many children take a packed lunch from home; others have school lunch, a cooked meal at the school for which parents have to pay. Secondary schools are much larger than primary schools and students may have to travel longer distances by school bus or public transport. Most secondary school students wear school uniform. The pupils learn some subjects such as: Mathematics, English Literature, English composition, Chemistry, Biology, Physics, History or the classics, one modern language, and one other subject, such as Art or Computer studies.
