You've flown halfway around the world；you've sniffed out this place that nobody in Falongland or Thailand seems to have ever heard of；so what on earth is there to do here？You consider this question as you sink into an old wooden beach chair that holds you above the sand.

It was a long journey from Bangkok to Huaplee.By the time you found the bus station and got yourself sorted out，it took almost as long as the flight from Falongland.

    Huaplee is located just south of Hua Hin，about two hundred kilometres from Bangkok，down the west side of the Gulf of Thailand. Not many tourists find this place，and the ones that do wonder if finding it has been their purpose all along.

    There's an apparent laziness that surrounds you here.It's what this place offers，and it's free of charge.The small waves that tap the shoreline seem to slow everything down.You settle into your beach chair in preparation for a long rest.You sit there and watch the sea.

    It's early afternoon，so the cook comes out and asks what you'd like to eat this evening.Before long he's rushed off to the market to buy the ingredients for whatever it was that you ordered－every meal fresh and to order.No menu here.

    There is no poolside noise here but just that wonderfully warm，clear blue sea.There's no street noise.The only sounds are the murmurs of nature.

    For now you just count your blessings (福祉)，listing them in the sand with your toe (脚趾)．You don't have to worry about being late for work. You don't have to do anything.

    The beach to your right stretches off to the horizon (地平线)，slowly narrowing to nothingness only to reemerge again on your left，now steadily widening until it covers the chair beneath you.Sand to your left and sand to your right; it's unbroken，endless.No start，no end，just sand，sun，and peace.Step off it，and you re­enter the world of traffic，stress，work，and hurry.

    Normally you're the type who can't sit still for more than ten minutes，but you're on Huaplee Lazy Beach now and，in the right frame of mind，it stretches all the way around the world.

     “How could it take me so long to find it？” you wonder.

    There are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.

    But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little in school. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may have many problems at their schools.

    You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, it may not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.

    Wild animals are our friends, but many of them are getting fewer and fewer. We should try to protect them. The four animals below are now in danger.

     Tibetan Antelopes

    Tibetan antelopes are medium - sized animals. They mainly feed on grass. They are usually found in groups of about 20. They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes. Although people can get the wool without killing the animals, people simply kill them before taking the wool. The number of them is dropping year by year. There are less than 75,000 Tibetan antelopes left in the world, down from a million 50 years ago.

    Golden Monkeys

    Golden monkeys are mainly found in Sichuan, Gansu, Shanxi provinces and Shengnongjia mountainous area of Hubei Province. Golden monkeys have golden - orange fur. They move around in the daytime, usually in groups of as many as 100 to 200 heads, or 20 to 30 heads. They feed on fruits and young leaves of bamboos. But people are destroying the environment where they live. Trees and bamboos are disappearing, so golden monkeys have less and less to eat.

    Elephants

    Elephants are very big and strong. They are bigger than any other animals on land. They are grey and have long trunks and tusks. They have poor eyesight, but very good hearing and smell. They can lift heavy things and break down branches with their trunks. Elephants are very friendly towards each other and towards their neighbours. Normally, they live in a group for many years. Young male elephants do not leave the group until they are about 12 years old. Now, there are very few elephants in the world. The number of them is becoming smaller and smaller because their living areas are used for fanning. Also, people hunt them for their tusks.

    Wolves

Wolves are not very big. They have grey fur. Solves have very good eyesight, hearing and smell. Wolves' food is various. They eat animals, insects and snails. They are friendly to each other and never attack people. They do not kill for fun. Wolves are in danger, too. They are losing their living areas because people cut down forests. Soon they will have no home or food.

    The purpose of a map is to express graphically the relations of points and features on the earth's surface to each other. These are determined by distance and direction. In early times distance was often expressed in units of time, for example “so many hours' march” or “a day's journey by river”, but such measurements gave more information about the relative ease of crossing the local terrain than they did about actual distance. The other element is direction, but for the ordinary traveller, whose main concern was “Where do I go from here?” and “How far away is it?”, the accurate representation of direction was not of primary importance. Partly for this reason, written itineraries (行程) for a long time rivaled maps. Even today, certain types of maps, for example, those showing railway systems, may make little attempt to show true directions. Similarly, obvious landmarks along a route were at first indicated by signs, realistic or conventional (惯常的), and varied in size to indicate their importance. Clearly the conventions employed varied with the purpose of the map, and also from place to place, so that in studying early maps the first essential is to understand the particular convention employed.

    The history of cartography (制图) is largely that of the increase in the accuracy with which these elements of distance and direction are determined and in the comprehensiveness of the map content. In this development, cartography has called in other sciences to its aid. For example, instead of determining direction by observing the position of a shadow at midday, or of a constellation (星座) in the night sky, or even of a steady wind, use was made of terrestrial magnetism (地磁学) through the magnetic compass, and instruments were evolved which enabled horizontal angles to be calculated with great accuracy.

    The application of astronomical concepts, and the extension of the knowledge of the world through exploration, encouraged attempts to map the known world. Then astronomers discovered that the earth is not a perfect sphere, but is flattened slightly at the poles, which introduced further refinements into the mapping of large areas. Meanwhile, the demands being made of the map maker were shifting significantly. The traveller or the merchant ceased to be the sole user of maps. The soldier, especially after the introduction of artillery, and the problems of range, field of fire, and dead ground which it raised, demanded an accurate representation of the surface features, in place of the earlier conventional or pictorial delineation (描绘), and a solution in any degree satisfactory was not reached until the contour (等高线) was invented.

    Sleep deprivation(缺失)is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests.

    It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected.

    In literacy(读写能力) tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group.

    Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta.

The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS)

    “I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show,” says Chad Minnich of the TIMSS and PIRLS International Study Center.

    “It's the same link for children who are lacking basic nutrition,” says Mr Minnich, based at the Lynch School of Education, Boston College. “If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it's having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction.”

    That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering.

    Considering that Sundarbans National Park is situated in thetropics, Septemberto March is the ideal time to come here. April, May and June are too hot while July andAugust often bring heavy season winds that limit travel and don't make for avery pleasant sightseeing experience. You can really enjoy doing lots ofcharming things in the Sundarbans during September to March.

    Take a river tour

    Most tourists who explore the Sundarbans arrive in KhulnaCity first. Fromthere, youcan join a boat tour that travels south along the Ganges River through miles ofpreserved forest all the way to Kotka, where there is a beautiful beach alongthe Bay of Bengal.

    Visit a bird habitat

    This bird habitat is a nesting place for dozens of tropicalbirds found in the Sundarbans. The best way to observe these birds isclimbing up the Sajnekhali Watchtower. If you're lucky, you'll also catch the famed BengalTiger making its rounds through the swampy jungle.

    Visit the Mangrove(红树林)Interpretation Centre

    If you wish to spend some time indoors out of the sweatyheat, goto the Mangrove Interpretation Centre. This place is very educational withmany posters, mapsand exhibits showing the wildlife and varieties of mangrove plants found withinthe park. You'llalso get to see crocodiles in a small pool.

    Take a tour of local villages

    Experience village life that has largely remained unchangedfor centuries. Inthis vast tropical region, there are villages made up of variousethnic groups who rely on fishing, farming and working in the localthrough growing tourist industry for their livelihoods. The Sundarbans is a UNESCO worldheritage site where you can visit villages and talk to locals,who will gladly sharetheir culture with you.
