Peru is a country    1    the Pacific coast of South America. It has three main areas: narrow, dry, flat land    2    (run) along the coast, the Andes Mountains and the Amazon rainforest.  It was the centre of the    3    (power) Inca Empire.   Spain    4    (take) control of   in the sixteenth century and ruled until 1821.It is for this reason    5    Spanish is the main    6    (office) language of Peru. The capital of the Inca Empire, Cusco, is found high in the Andes. It is a     7    (popularity) tourist destination as it is close    8    the famous Inca ruins of the city of Machu Picchu. Cusco is a lively city with many    9    (hotel) and inns,     10    both Indian and Spanish culture and art can be seen.

The Sanjiangyuan area, known     1     China’s “water tower”, contains the headwaters of the Yangtze, Yellow and Lancang rivers.     2     (locate) at an average altitude of more than 4,700 meters, Sanjiangyuan National Park is the     3     (high) national park in the world, covering     4     area of 190,700 km² and boasts one of the most various biodiversity (生物多样性) in the world at the highland.

Every year, tens of thousands of Tibetan antelopes (羚羊) start their migration to Hoh Xil in May     5     (give) birth and leave with their young children in late July. During the 1980s and 1990s, the population of Tibetan antelopes here     6     (drop) to less than 20,000. Thanks to the country’s efforts in recent years, Hoh Xil is now home to more than 70,000 Tibetan antelopes. Recently, the reserve (保护区)     7    (list) as a “key wetland protection zone”,     8     the environment, animals and plants will get effective protection.

By promoting the development of a natural reserve system with national     9    (park) as the main body, more than 75 percent of wild plants have been     10     (sufficient) protected, helping to build a national gene bank for the genetic resources of wild organisms on the Qinghai-Tibet Plateau.

For Greek photographer George Doupas, Beijing is home now. During the past decade, he has been photographing the city, capturing its beauty and sharing these     1    (photo) online and in exhibitions.

“This truly represents Beijing-the old and the new, nicely mixing together,” Doupas said while showing his photograph of the Zhihua Temple,     2     beautiful Ming Dynasty building. It is located in front of a modern office building, Galaxy SOHO, which     3    (feature) weaving bridges and interlocking passageways (通道).

With rich historical heritage, Beijing     4    (be) an important center of traditional Chinese culture since the Ming Dynasty. Doupas often gets lost in the city’s splendid ancient architecture. Meanwhile, he is also amazed by the modern city     5    (combine) high-end businesses and various industries. “It is fascinating to see a city developing at such an     6    (incredible) rapid rate and investing so much effort in preserving its past, which is     7     I decided to pursue my career here ,” he said.

    8     (dedicate) to his career as a photographer in China, Doupas hopes to serve     9     a bridge between China and the West. The displays that show his photos about Beijing have attracted a large audience in Greece and the Czech Republic.

“My     10    (occasion) stay in Beijing has turned into permanent residence, and I call Beijing my home now,” he said, “I will keep sharing photos of China with the rest of the world.”

Peru is a country on the Pacific coast of South America,    1    includes three main areas: narrow, dry, flat land    2    (run) along the coast, the Andes Mountains, and the Amazon rainforest. In the high plain area is Lake Titicaca, the highest lake in the world, on which boats can travel. Peru has abundant plants from desert grasses    3    vast areas of jungle.

Peru    4    (take) control of by Spain in the 16th century until 1821. So Spanish is    5    (official) spoken in Peru. The ancient Inca capital, Cusco, is a popular destination for the    6    (tour) as it is close to the famous Inca ruins of the city of Machu Picchu.

There are two especially interesting things    7    (admire) about the Inca civilization. The first is the roads and paths they built to connect    8    (they) important cities. Second, the Inca built wonderful cities,    9    there were no markets in these cities. One of the interesting    10    (question) of history is how the Inca lived without shopping.

9 . It seems we can’t get off the planet fast enough. Two thirds of NASA’s money is spent on manned space exploration, and that number will grow with the USA’s decision to send a man to Mars in 2037. We’ve seen all there is to see on Earth, right? Wrong. The final place is here, under the surface of the sea.

Heading down into the ocean, human limits are quickly reached. At 200 metres, the water is as black as a moonless night. Most nuclear submarines (核潜艇) would implode (内爆) before they reach 1 km down. At 3 km — still less than the average depth of the ocean — there’s a good chance that you’ll discover a new species. The deepest­diving whales go no further. At the very bottom, about 11 km down, lies the Challenger Deep, the deepest part of the Mariana Trench in the Pacific Ocean. Eighteen humans have walked on the Moon, but only three have seen the Deep with their own eyes.

Yet things live down there. Big things. A very loud sound was once heard and scientists suggested that it was produced by an animal bigger than a blue whale, the largest creature known on the planet.

In the late 1990s, a deep­water submarine was dropped in the Southern Ocean, and passing 4,000 metres, it discovered something huge passing under it. Surprised? Don’t be. The ocean covers 70% of the planet’s surface and we’ve studied less than 5% of it. We know more about the dark side of the Moon than about the bottom of the sea.

One reason that we explore space is to find evidence of other life forms. The search for life outside of Earth is important, but robots can look under the dry rocks of Mars better than humans. They’re absolutely important for doing ocean research too, but they can’t look under the sea. The cost of exploration is rising, but the results would benefit all our lives. Understanding the oceans will help us find new sources of food, drugs and energy.

Perhaps now it's time to begin a new period of sea exploration. Manned exploration of space is science fiction (科幻小说). The adventure of the deep sea is science fact.
