Through the following four cultural relics, the world has known about Korea's cultural treasures.

Pulguksa Temple

    Pulguksa Temple plays an important part in the history of Korean temples. The building of Pulguksa Temple began in 751. In the year 774 the large temple was finished, becoming an important center for Korean national-protection Buddhism(佛教). The way used to create the store structure gave the temple a look of beauty. The building thus represents the excellent Korean sculpting(雕刻).

Sokkuram Cave

    Sokkuram Cave is a man-made cave, which has been sculpted from white stone in special sculpting ways. In the cave, a seated Buddha is the main statue. On the walls around him are found 38 other statues and the Four Heavenly Kings. This stone cave is one of Korea's greatest places, built when Shilla's religion, science and sculpture were at the height. It shows Shilla's knowledge of math, physics and art.

Haeinsa Temple

    Haeinsa Temple's Changgyong Panjon (藏经板库) is a world-class cultural treasure. It has 81,340 wooden blocks. Millions of Chinese characters were caved on the blocks. In addition to its artistic value, it is famous as the oldest Buddhist canon(教义)in the world today. The building is beautiful. What's more important is that its design allows for natural wind as well as temperature control. Each book is 69.5cm in width and 23.9cm in height. There are 23 lines on each of the blocks and each line contains fourteen characters.

Changdokkung palace

    Changdokkung palace, one of the five places of the Chosen Dynasty, was built in 1405. The oldest structure is Tonhwammun Gate. Other ancient buildings include Injongjon hall, Sonjongjon Hall and Taejojon Hall. The back garden for kings remains a great example of the ancient Korean scenery.

    A “virtual (虚拟的) cocktail” glass that lets you change the flavor (味道) of your drink using your Smartphone has been developed by scientists.

    Offering a customizable (定制的) range of drinks and tastes, the Vocktail can change a glass of water into a cocktail at the press of a button. The world's first technology tricks your brain into thinking it is experiencing a specific flavor by fooling your senses of sight, smell and taste.

    Developed by researchers at the National University of Singapore, the glass' three sensory components are controlled via a Smartphone App. Because the software can combine a number of smells, colors and tastes, the Vocktail can create almost any flavor.

    Developer Nimesha Ranasinghe said: “Our approach is to increase drinks flavor experience by overlaying outer sensory stimuli (刺激物). For example, in the Vocktail we overlay color, taste and smell sensations to create an adjustable flavor experience. Flavor is mainly how we feel food and that is achieved through the use of these senses. Therefore, by changing the color of the drink, using different smells and changing the taste through electricity, we are able to copy the flavor of a drink without it actually changing the liquid.”

    The glass houses three fragrance containers connected to micro-air pumps. The pumps release smell that change your feeling of the drinks, flavor. For example, a lemon fragrance will trick your brain into believing it is tasting lemon-flavored drink.

    On the outside edge of the glass are two electrode strips (电焊条) that send electric pulses into your tongue to stimulate your sense of taste and flavor differs with different pulses.

    The wonderful experiment I am going to introduce proves that air is just all around and that it presses down upon us. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface.

    The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！

    What you need:

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method:

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4）Quickly sit the egg on the neck of the bottle.

Result:

    Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

    Why it happened

    As the paper burns, it needs oxygen and uses up the oxygen（air）in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.

    Plan your dream vacation to one of these excellent destinations.

    St. Lucia

    Abundant（丰富的） rainforests and splendid mountains are all reasons to visit this Caribbean island. St. Lucia offers the perfect mix of relaxation and adventure. To take in the breathtaking scenery, plan to hike the Piton Mountains or dive in the waters of Anse Chastanet.

    Banff. Alberta

    This Canadian destination will bring out the explorer in anyone who visits. From hiking and whitewater rafting to skiing and snowboarding, Banff offers travelers an abundance of year-round outdoor activities. The Lake Louise Ski Resort is one of the largest in North America and the striking photo opportunities of the Canadian Rockies from Moraine Lake can't be underestimated (低估).

    Machu Picchu

    According to travelers, a visit to this Peruvian UNESCO World Heritage (遗产) site is a once-in-a-lifetime adventure. Located in the Andes Mountains, it is the most familiar icon (象征物) of Inca civilization. Spend a few days accustoming yourself to the altitude in the neighboring city of Cusco, where you can experience a mix of Incan and Spanish cultures.

    Great Barrier Reef

    It's easy to see why the Great Barrier Reef is one of the Seven Natural Wonders of the World – it stretches nearly 1,500 miles along the eastern coastline of Australia and features about 3,000 reefs, 900 islands and more than 1,500 species of fish. Travelers can see these amazing natural structures from the air or underwater. However, large amounts of coral bleaching (褪色) caused by rising ocean temperatures put this place's continued existence at risk, so plan your visit soon to see this awesome sight up close.

    The nervous-looking young man had waited for a few moments—outside the jeweler's before he got enough courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully and told him he'd better buy a necklace. He wasn't used to buying jewellery and was a little worried about over-spending.

    After some discussion as to a reasonable price and the type, the assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop promising to return at five o'clock. When, half an hour later than planned, James did return to the shop with his future wife, Laura, the assistant acted as if she had never seen him before. When she was asked to show them some necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the one she had prepared. A choice was soon made and they went away, satisfied. James would certainly come back to buy what he wanted.

    When many people are worried that there are no more heroes in modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist (存在).

    According to the Inner Mongolia Morning Post, the accident occurred on the afternoon of December 14, 2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water.

    More than 20 university students who happened to be near the spot immediately went to the rescue of the children.

    Two children were quickly rescued, but the third died. The child's body was not found for three hours. Two of the rescuers, Liu Ye and Hao Longbiao, also died of cold and exhaustion (筋疲力尽).

    The body of Hao who took the lead in jumping into the lake was not found until the next day.

    A student who was unwilling to tell his name said he and his classmates from the local college were taking photos at the lake. When they heard the children's cries for help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water.

    Local residents held mourning ceremonies (祭奠仪式) at the lake.

    Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation, but their lives were no longer in danger.
