The Great Wall winds its way from west to east, across deserts, upon mountains, through valleys till at last it reaches the sea. It is one of the most famous places of interest in China and Chinese people are very proud of it. Every year a lot of people came to the Great wall to feel the     1     (great) of the ancient people.

The Great Wall has     2     history of over twenty centuries. The first part of it     3    (build) during the Spring and Autumn Period. During the Warring States Period,     4    (many) walls were put up to defend the borders of the different kingdoms. During the Qin Dynasty, the Emperor Qinshihuang had all the walls    5    (join) up. Thus, the Great Wall came     6     being.

    7    was very difficult to build such a wall in the ancient days without any modern machines. All the work was done by hand.     8    (thousand) of men died and were buried under the wall they built. It was made not only of stone and earth,     9     also of the flesh and blood of millions of men.

Today the Great Wall is a place of interest not only to the Chinese but also to people from all over the world. Many people know the famous Chinese saying: “He     10     does not reach the Great Wall is not a true man.”

7 . Fossils are well preserved remains, impressions, or traces (痕迹) of animals and plants that lived long ago. Paleontologists (古生物学家) divide fossils into two main groups. Some fossils, called body fossils, show the structure of the plant or the animal. They form directly from the remains of plants and animals. Other fossils, called trace fossils. They record signs of animal or plant activities, such as walking, feeding, scratching, or even resting.

Most animals and plants don’t become fossils after they die. They break down into little bits or may be eaten by other animals. But some remains get buried too fast, avoiding those things happening. An animal might die near a body of water and sink to the bottom, where its remains get covered in sediment (沉积物). As sediment builds up, mineral-rich water seeps into the remains, leaving minerals in the tiny spaces of the bones and even replacing the original bones. The new minerals react with those in the animal’s remains and then harden into fossils.

Most fossils are buried deep in the Earth. As the Earth’s surface changes, scientists can dig up new fossils and learn more about past life and the Earth’s history. In rock that formed before a certain time, roughly 2.8 million years ago, scientists will not find human fossils.

Fossils are our keys to understanding prehistoric life and the Earth’s history. By studying fossils, we learn about a great variety of plants and animals that lived in the past. We can know what they looked like, how and where they moved and what they ate. By comparing fossils from different time periods, we can track the evolution of a species, see how it adapted to changes in its environment, and understand more about the climate and environment where the fossils were buried.

8 . One of the most common beliefs among researchers is that humans first arrived in North America 16,000 years ago. According to a recent fossil discovery, that might not be true. The new finding suggests that humans might have arrived in North America far earlier.

In 2013, a damaged mammoth (猛犸象) skull and other bones that looked “deliberately broken” were found. The damage to the bones suggested that humans were the ones who caused it to make tools. Carbon- dating analysis suggested the pieces are roughly 37 ,000 years old. This discovery could shift our understanding of humans ‘earliest existence in North America. These fossils suggest humans killed animals in the area much earlier than 16, 000 years ago.

Previous research led scientists to believe the first humans that settled in North America belonged to the Clovis culture. This was a group of people who left behind carefully made tools 16,000 years ago. However, carbon-dating analysis of the mammoth bones indicates that the site is around 36, 250 to 38, 900 years old. That means it’s the oldest known site left behind by ancient humans in North America.

“That’s not the only interesting thing about the discovery,” said Timothy Rowe, a professor at the University of Texas. “The similar findings supporting an earlier date for human arrival have been mostly ignored. This is because they have contradicted previous research.”

Now, however, he thinks there’s a good chance that researchers will find evidence of humans farther back in time.

The early humans shaped bones into sharp blades, which were used to take apart animals’ remains, according to Rowe. There are also signs that they cooked the animal bones over a fire to melt off the fat. “The real evidence that we have has to do with the breakage patterns, and how thorough they are. They must have used rocks or hammer stones to bust the skeleton apart... These people would use whatever they could,” Rowe told USA Today.

9 . Here are some properties that the British royal family owns.

Buckingham Palace	The most famous palace for the British monarchy(君主), Buckingham Palace, is easily recognized. It was originally built for the Duke of Buckingham in 1703 and acquired by King George Ⅲ in 1761 and has remained in the royal family ever since. This is where the family tends to greet visitors and crowds, and serves as the administrative offices of the monarch of the United Kingdom. It is valued at $4.9 billion.
The Diamond Diadem(王冠)	This Diamond Diadem was made in 1820 for George Ⅳ, which was regularly worn by Queen Victoria after it was reset with jewels from the royal collection. Queen Elizabeth Ⅱ wore it in 1953. The jewelry experts estimated it to be worth around $ 6.9 million.
Painting by Claude Monet	The royal family is known for its extensive art collection as well. This is “Study of Rocks; Creuse: ‘Le Bloc’” by Claude Monet (1840-1926). In 1949, Queen Elizabeth the Queen Mother purchased it for $2,300, and by the time of her death in 2002, it was worth about $17,000. The Monet painting hung in her main residence at Clarence House for several years, but is now on display at Buckingham Palace.
Tower of London	It’s built in 1066. It’s not a working palace any more, but it used to be. The Tower of London, officially called His Majesty’s Royal Palace and Fortress of the Tower of London, now functions as a museum and is a protected World Heritage Site due to its extensive history. It’s also the single most valuable piece of property in the United Kingdom, estimated to be worth about $81 billion.

Chinese cultural relic authorities on Thursday revealed some new discoveries from the mysterious Sanxingdui Ruins in Sichuan Province.    1    (recognize) as one of the significant ancient remains in the 20th century, the 3000-year-old Sanxingdui is a national treasure buried with a variety of jade，bronze(青铜) and gold objects. Among the excavated artifacts(出土文物)， a complete gold mask about 10 grams in     2     (weigh),37.2 centimeters wide,and 16.5 centimeters high    3     (unearth)from No.3 Pit a few days ago. The gold mask is    4       (basic)the same size as one of the bronze heads dug from the same pit. Therefore, experts assume it was initially attached     5     the face of a bronze head.

Meanwhile,     6    big bronze mask was excavated from the pit. It is the     7     (large) bronze mask ever discovered at the site. The bronze mask has struck the fancy of Chinese netizens,    8     comments on the hairstyle reminded them of the crown-shaped hat worn by Zhuge   Liang , a Chinese statesman and military strategist that lived during the Three Kingdoms period.

Totally; the archaeologists(考古学家)    9    (discover)more than 500 pieces of relics over the last few months, impressed with the historical     10     artistic value.
