Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.
What to Expect
The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.
Accommodation Zones
Homestays are located in London mainly in Zones 2, 3 and 4 of the transport system. Most hosts do not live in the town centre as much of central London is commercial and not residential(居住的). Zones 3 and 4 often offer larger accommodation in a less crowded area. It is very convenient to travel in London by Underground.
Meal Plans Available
◇ Continental Breakfast
◇ Breakfast and Dinner
◇ Breakfast, Packed Lunch and Dinner
It's important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal(谷物类食品), bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinners usually consist of meat or fish with vegetables followed by dessert, fruit and coffee.
Friends
If you wish to invite a friend over to visit, you must first ask your host's permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.
Self?catering Accommodation in Private Homes
Accommodation on a room?only basis includes shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long?stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.
1. The passage is probably written for________.
A. hosts willing to receive foreign students
B. foreigners hoping to build British culture
C. travellers planning to visit families in London

15. C。句意：这项实验表明如果定期进行适量锻炼的话会改善我们的健康状况。此处为if从句的省略形式，完整的句子为：...if they are carried out regularly，...。根据省略原则，把相同的主语和系动词be省去。
