听力原文：Denis: Hi, there, Fiona.Fiona: Hi, Denis.Denis: This semester is coming to the end at last. After a semester of hard study, I really need a good rest.Fiona: Have you got any idea for your holiday?Denis: Yes, I'm going to join an Italian tour.Fiona: Great.Denis: How about you?Fiona: I will go to Australia to study English.Denis: Why to Australia?Fiona: Because it is the closest English speaking country to Thailand.Denis: When will you leave and how long will you stay there?Fiona: I'm going to leave next Monday and spend the whole holiday there.Denis: So, that is to say, you are going to study in a summer school.Fiona: Not exactly a summer school. It is only a more relaxed way to study English in Australia—as part of a vacation. Visitors on a tourist visa can undertake English study for up to three months.Denis: Besides studying in class, are there any out-of-class activities?Fiona: Certainly there are. One particular popular option is called Foundation Studies. It combines preparation for undergraduate university studies with improving one's ability to speak, read, understand and listen to English. Another popular option is a 'farmstay' where visitors are able to learn English while experiencing life on a cattle or sheep station.Denis: It must be very interesting. Have you registered for a 'farmstay'?Fiona: Yes, I will stay in a sheep station for two weeks.Denis: It's so attractive. I should have talked to you earlier. Then maybe we could go to Australia this vacation together.Fiona: It's a pity. But I am going first and then I can tell about you my experience there. So you may have a better preparation.(20)A．Italy.B．England.C．Australia.D．Thailand.
