Ball games are a big source of modern amusement. But they're nothing new. For instance, consider a 4,500-year-old ball     1    (find) in a child's tomb in Egypt or 3.600-year-old rubber balls from Central America-where the competitors were asked to play the balls with their hips(臀部）.

So far, researchers     2    (make) sure of a date of the oldest sporting balls in Europe or Asia: three balls, dug up from the tombs of horsemen in the deserts of northwestern China and crafted three thousand     3    (year) ago.

＂We are quite sure they were used in some sort of bat-and-ball game."Patrick Wertmann is an expert at the University of Zurich     4     analyzed the ancient sporting equipment. The balls are about three inches in diameter and filled     5    leather hair. “And then, also,     6    (look) at the Chinese character of "ball" itself, you'll find it quite     7    (interest) because this character is made up of the ideograms(表意文字）of hair and leather.”

As for how this ancient ball-and-stick game     8     （play)? “lt could be something like polo. But it could also be something like     9     early form of golf.

Since we don't have any textural evidence and we don't have any sticks from the same period, we don't really know     10    （exact).”

It’s almost time for me     1     (say) goodbye to Australia. I     2     (enjoy) my time here very much. After being here for a while, my biggest impression is the complicated mix of peoples and cultures     3     make up the nation. Although the main cultural influence     4     1788 has been Westen culture, minority cultures have also played a part in shaping the unique Australian culture, with many of the new     5     (culture) influences contributed by immigrants. It is said that now nearly half of all Australian citizens were either born overseas     6     have parents who were born overseas.

    7     (personal) speaking, what I like most about Australia     8     (be) the people themselves.     9     have a straightforward and free-and-easy attitude towards life, and their friendliness and warmth made me feel at home wherever I went. After experiencing Australia, I have to say that I agree     10     the tourism slogan: “There’s nothing like Australia.”

A group of students from England, who are interested in archaeology, have come to the Zhoukoudian caves for a visit. An archaeologist     1     (warm) gives them a brief introduction     2     the life and habits of the earliest people there.

Early people lived in caves and they made fires in the centre of caves     3     (keep) themselves warm, cook the food and scare their enemies away, such as tigers and bears. They might have kept the fire burning all winter because layers of ash almost six metres thick have been excavated.

Early people did wear clothes made from animal skins. They used sharpened stone     4     (tool) to cut up animals and remove their skins. Smaller scrapers     5     (use) to remove the fat and meat from the skin. Finally using needles     6     (make) of animal bones, they would sew the pieces together.

Early people also paid attention to their     7     (appear) and wore necklaces. Some of the necklace beads were made of animal bones but some were made of shells,     8     told us that all the fields around Zhoukoudian caves used to be part of     9     large shallow lake. They moved around, following the herds of animals. They didn’t grow their own crops, but picked fruit when it     10     (ripen) and hunted animals.

I experienced the Naadam Festival in China’s Inner Mongolia Autonomous Region for the first time this year. Naadam means “games” in Mongolian, and it     1    (represent) by three events: horse racing, wrestling, and archery. Mongolian wrestling is different from the wrestling in the Olympic Games. There are no rounds, and     2    (wrestle) are not separated by weight. Though the three events all left a deep impression     3     me, I liked horse racing best. I was surprised     4    (see) that riders were boys and girls! People say it is     5     children are lighter and the horses can run faster and farther.

Our grandparents seems to have magic powers sometimes. Give them a Chinese lunar calendar    1    they will know what the weather will be like days or even months later.

What's the secret? They are following the 24 Solar Terms (节气),     2    were added on Nov. 30 to the list of Intangible Cultural Heritage of Humanity (人类非物资文化遗产) by the United Nations (UN). It is a knowledge system and social practice    3    (form) through people's observations of the sun's annual movements and its influence on the climate.

The 24 Solar Terms    4    (come) into being during the Qin and Han    5     (dynasty). At that time, most Chinese people made their living on farms, so weather changes were    6    (extreme) important for them. But of course, they had no satellite, internet or weather broadcast    7    (help) them.    8    these difficulties, they managed to work out 24 Solar Terms by studying the sun's movement and also    9    (pay) attention to other natural changes such as air temperature, water and crop growth.

It is honored as China's    10    (five) great invention, after papermaking, printing, the compass and gunpowder. Now, it is still widely used in daily life even in the age of technology-based modern farming.
