Host family accommodation, or living with host families, remains popular among language travel students for its advantages. These days, host families are trying to offer more in terms of quality, for they still have something to worry about.

Host family accommodation is often seen as the number-one choice for advantages in language study, cultural communication and cost of living. Staying alongside host families enables students to get enough practice for the short time of their studying so that their language acquisition is likely to become faster. Living in host families also has the advantages for students of being able to spend a lot of time communicating with their “host parents”, and get to know the local way of life, people and culture. Another advantage is that host family accommodation can sometimes be the least expensive. It attracts students for it ensures them a family type of living at a low cost.

The advantage, however, have not prevented host families from worrying. On one hand, some host families are losing their unique selling point. The problem is that the majority of hosts in big cities, now generally single and young, have less time available for students, but the selling point for host family accommodation is communication practice. On the other hand, students’ expectations have risen. They are becoming more demanding and asking for more than ever from their accommodation, as they come mainly from high socio-economic groups in their own countries.

To get out of the difficult situation, host families are now making efforts to improve the quality of service. They are trying to make living conditions better, including broadband（寬帶） Internet service, private bathroom, and access to plenty of hot water for long showers. They are also providing students with structured family activities.

It is believed that host family accommodation will keep the popularity vote with language travel students.

GUATEMALA CITY （Reuters） – A fish that lives in mangrove swamps(紅樹沼澤) across the Americas can live out of water for months at a time, similar to how animals adapted(適應) to land millions of years ago, a new study shows.

The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圓木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.

The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.

The new scientific discovery came after a trip to Belize.

 “We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.

In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.

Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.

Further studies of the fish may tell how animals changed over time.

 “These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(過渡) from water onto land,” Wright said.
