    Great changes have been taken place in my village. Ten years ago, the small and low houses of my village lie on the north of a lake. The villagers produced many waste. As a result, the lake was serious polluted. To the west of the village was a sandy field, where was the source of much dust.

    Now the poor house have been replaced by green trees. However, the sandy field that the villagers used to plough has been covered of fruit trees. On the lake, now clean and clear, the villagers often spend their spare time fish.

    In word, my village has become a green one.

National Gallery of Canada (Ottawa)

    This museum has a great collection of art spanning the Middle Ages to the present day, including American, Indian, European, Inuit and Canadian works. It offers a unique, near-complete overview of Canadian art — from early Quebec religious work, through Inuit work from the 1950s, to the contemporaries.

Tokugawa Art Museum (Japan)

    The Tokugawa family reigned over Japan from 1600 to 1868. Under them, the country enjoyed the longest period of peace in its history. This time span is also known as the Edo period, during which the arts flowered in Japan. Artists of this period directly influenced Western masters such as Monet, Gauguin and Whistler and have since gone on to become household names. Other exhibits effectively present, through accurately reproduced environments, aspects of Japanese life at the time.

    Museum of Fine Arts (Boston)

    Highlights of this museum's collection include a 4th-century Christian marble bust (半身像) of St. Paul at prayer, and a painting that questions life and our very existence, Gauguin's “Where do we come from? What are we? Where are we going?” It's a must — go in the US.

The Egyptian Museum (Cairo)

    As well as gathering together some of the finest archaeological finds from all Egypt, this museum also provides a rare opportunity to simply pop in and within minutes be standing face-to-face with one of the greatest works of mankind, Tutankhamun's golden mask. A portrait of unbelievable quality, craftsmanship and beauty, the highly polished gold face — at once a god, a king and a teenager — shines like water: delicate, yet untouchable all at the same time.
