The Yangtze River,     1    (know)in China as the Chang Jiang, is the longest river in Asia and the longest in the world to flow entirely within one country.

Driven by the     3    (curious) in my heart, I came to China and took part in a cruise(巡航)along part of the river last year.

Life on board was relaxing with plenty to occupy the time and mind. We passed Wuhan    4     in 1966 Chairman Mao, then in his 70s, famously swam across the Yangtze. Glorious temples rise over industrial ports while, high above the rocks, ancient coffins are hung in caves without being disturbed for    5    (century). We also visited The Three Gorges Dam,     6     symbol of Chinese pride and power. As well as enormous hydro﹣electric output,     7    (it) increasing shipping ability benefits Chinese people quite a lot.

2 . If you think about World Heritage Sites, you probably think of places connected with ancient art and culture, historical buildings and monuments. And of course, many of these are on the World Heritage List (WHL) (世界遗产名录). But the WHL contains a lot of sites that are not so obvious. Let’s look at a few of them.

Robben Island in South Africa

This island was used through the centuries as a prison, a hospital and a military base. But it’s probably most famous as a maximum-security prison for political prisoners in the twentieth century. Nelson Mandela was one of its most famous residents. The WHL says it represents “the triumph of democracy (民主) and freedom over oppression and racism”.

Borders of France and Spain

This is an area of great natural beauty and the mountains have many interesting geological formations. But it is also an area of small farms. People there still use a type of agriculture (农业) that used to be common in mountainous areas of Europe but that has almost completely disappeared in modern times.

The city of Brasilia, Brazil

Brasilia is a capital city that was created from nothing in 1956. The WHL calls it “a landmark in the history of town planning”. The different areas of the city and the buildings themselves were all designed at the same time carefully. Every part of the city shows the ideas of the planner and architect.

Simien National Park, Ethiopia

Simien National Park was one of the first sites to be listed in 1978. It is one of the highest mountainous areas in Africa, and the WHL calls it “one of the most spectacular landscapes in the world”. It is also important for its wildlife. The population of some rare animals is getting smaller and smaller.

3 . Dark Sky Parks around the World

Warrumbungle National Park

Situated in the central west slopes of New South Wales is Australia’s only dark sky park, Warrumbungle. The park has served as a dark sky park since July 2016. Its crystal-clear night skies and high altitude make it a natural, educational, and astronomical heritage site in the southern half of the earth. Tourists can use Australia’s largest optical telescope within the park boundaries to view the auroras(极光)，the Milky Way, and faint shooting stars.

Sark

Sark is a Channel Island near the coast of Normandy under the protection of the UK. It was the World’s First Dark Sky Island set up in January 2011. Its historical and cultural blend attracts over 40,000 tourists annually. With no motor vehicles and public lighting on the island, there is an exceptional view of the dark skies. A rich Milky Way is visible in the dark night skies from the shores of the island.

Pic du Midi de Bigorre

Pic du Midi de Bigorre in France was designated as a dark sky park in December 2013 making it the second largest dark sky park in the world. The park covers 3.112 square kilometers spread across the Pyrenees National Park and UNESCO’s World Heritage site, Pyrenees-Mont Perdu. The park attracts over one hundred star watchers every year. The Observatory Midi-Pyrenees, which was built in 1870, is one of the world’s highest museums at a height of 2,877 meters above sea level.

Ramon Crater/Makhtesh Ramon

Ramon Crater is a unique 1,100-square-kilometer nature reserve located in the Negev Desert in Israel. In 2017, the Ramon Crater became the first designated dark sky park in the Middle East. Its location, rough climate, and forbidding landscape that are characteristic of the Negev have largely defeated historical attempts for human settlement, making it a great place to view the night skies. Stargazers usually camp in the desert to have an uninterrupted view of the stars, planets, and the Milky Way.

4 . Rivers play an important role on the earth, and we can't imagine what the earth would be like without rivers.       1    

With a length of 6, 650 kilometers, the Nile is the longest river in the world. The Nile River has been the source of human civilization since ancient times. The Nile has two main branches—the White Nile and the Blue Nile. The White Nile starts from the Great Lakes region of East and Central Africa through Lake Victoria.    2     The Blue Nile carries with it a lot of fertile soil which turns out to be very important to farming in Egypt.

The Amazon River is the world's largest river with a width of about 40 kilometers during the rainy seasons but about 10 kilometers wide when it is not flooded. The Amazon River has such a big water volume that it accounts for(占.....比例) more than 20% of all the world’s fresh water—far more than any other river.     3    The main Amazon River flows mostly through Brazil and Peru but its tributaries can also be found in many other countries.

    4    It has a depth of about 250 meters. Its length is 4, 700 kilometers. The sources of the Congo River are in the highlands and mountains in the Eastern Africa Rift Valley. It's the second largest river in terms of water volume.     5    The Congo River basin(盆地) is the catchments(流域，集水区) area of the Congo River. It lies in both north and south of the Equator, making its flow very stable as there are always some tributaries experiencing a rainy season at any time.

A．Some of them are worth mentioning.
