4 . Longing for the most amazing places on the planet? You can do no wrong with these lakes across the globe.

Five Flower Lake

Set in the striking karst landscape of the Jiuzhaigou Valley in Sichuan province, China, Five Flower Lake is extraordinarily clear, with visibility to a depth of 40 metres. Five Flower is one of a series of blue-, green-and sky-colored lakes blocked by rock falls, but it differs from the others as its waters change color, looking sometimes yellow, sometimes green, but usually diamond blue. In winter, Five Flower never freezes; in summer, it never dries up. Local wildlife living in the surrounding mountain forests include the rare giant panda and the golden snub-nose monkey.

Crater Lake

The deep-blue waters of Crater Lake in Oregon, US, fill the outlet of an ancient volcano that collapsed 7,700 years ago. Its strangest occupant is the “Old Man of the Lake”, a nine-metre-tall tree stump(树桩), which has stood upright in the water for more than a century. No rivers or streams enter the lake. Water loss in summer is compensated by winter snow and rain, the entire body of water being replaced every 250 years.

Lake Ohrid

Ancient Lake Ohrid has been around for about five million years and crosses the mountainous border between Macedonia and Albania. It has unique plants and wildlife, including the Ohrid “plashica”, a fish native to the lake, whose scales(鳞片) are used to make Ohrid pearls.

Lake Maggiore

Surrounded on three sides by the Lipontine Alps and touching the plain of Lombardy to the south, Lake Maggiore is Italy’s longest lake. Considered part of the country’s lake district, it is shared with Switzerland. Characterized by a Mediterranean-style climate, temperatures here are mild all year. This has given rise to some of northern Italy’s most wonderful gardens, which appear to float like flower-decked boats on the water.

5 . The UNESCO World Heritage List is a prestigious honour awarded to sites of outstanding universal value around the world. Did you know there are 1,157 UNESCO World Heritage Sites spanning across 167 countries? We’ve picked out our top 4 for you to visit below.

The Acropolis, Greece

The Acropolis is an ancient castle that stands proud in the Greek city of Athens. Back in the fifth century BC after battle with the Persians, the plans of Pericles came to life under the influence of Pheidias, the sculptor. It then became a place for thought and art to flourish, where symbols of classical spirit and civilisation came alive.

Historic centre of Rome, Italy

According to Roman mythology, the Eternal City was founded in 753 BC and became the capital of the mighty Roman Empire. Rome is home to a number of attractions including the Forum, the Pantheon and the Colosseum! This World Heritage site contains the whole historic centre within the city walls and reflects the influence of the Renaissance and Baroque periods in making it one of Italy’s most popular cities.

Ayutthaya Historical Park, Thailand

The historic city of Ayutthaya in Thailand was founded around 1350 and was subsequently destroyed in the 18th century by the Burmese. What’s left today is the ruins and some key highlights include the Buddhist temples of Wat Ratchaburana, Wat Mahathat and Wat Phra Sri Sanphet. The area is home to the remains of tall prang (reliquary towers) and should not be missed.

Cultural landscape of Bali, Indonesia

The landscape in Bali is unlike anything else on Earth. Consisting of five rice terraces (梯田) and water temples covering 19,500 hectares, the cultural landscape takes your breath away. This site gains honour through an ancient farming ceremony dating back to the 9th century known as subak. This concept reflects the spirit, the human world and nature, also known as Tri Hita Karana.

7 . What if someone told you about a kind of grass as tall as the tallest trees? A grass as strong as steel? Would you believe that person? You should, for that grass is bamboo   (竹子), which has more than 1,000 uses. It is not just a material for making useful products. Young bamboo is eaten, often mixed with other vegetables.

Bamboo grows in many parts of the world. In the USA it grows in many states like Virginia and Florida. Most bamboo, however, is found in wet and warm climates, especially in Asia and on the islands of the South Pacific Ocean.

In most Asian countries, bamboo is nearly as important as rice. This unusual material is used to not only build large buildings but also make water pipes, musical instruments and paper. There are over 1,000 kinds of bamboo. No wonder the lives of nearly half the people on earth would change greatly if there were no longer any bamboo.
