Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?

Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.

The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.

Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.

“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.

“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”

What is Home stay? Literally it is a home for you to stay at when you are not at home. To be specific, home stay provides foreign language students with the opportunity to speak native language outside the classroom and the experience of being part of a British home. Here is what you will experience in our British Home-stay Program.

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 of the transport system. Most hosts do not live in the town centre (Zone 1) as much of central London is commercial and not residential(居住的). Zones 3 and 4 often offer smaller accommodation in a more 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 desert, 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.

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.

Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.　

Be always in a good mood. There is a relation- ship between the mood and health. A good mood keeps you in high spirits. Thanks to the internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy.　

Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.　

Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.
