2 . The Qingming Festival is celebrated with a three-day national holiday, whose name originates from the saying “Plants start to revive and prosper at Qingming in a clean and bright way. Thus, the festival is called Qingming,” which means clean and bright.     1    . Tomb sweeping aims to commemorate family ancestors while going on a spring outing allows everyone the chance to enjoy the beautiful scenery and enjoy the season.

Tomb sweeping.     2     on this day, the whole family gathers in front of their ancestral tombs. They offer fruit and wine to their ancestors and clean the weeds from around the tomb. Finally, they kowtow and pray, hoping for their ancestors' blessing for the rest of the year.

Spring outing. The time around the Qingming Festival is one of the most suitable seasons fora spring outing, as plants are thriving and flowers are blooming. People can have a great time outdoors with their friends and family.     3    

Qingtuan, a green rice ball tiny enough to fit into your hand, is also called Qingmingguo or Aiguo.     4     It is a mixture of sticky rice powder and green vegetable juice. stuffed with sweetened bean paste, Qingtuan tastes sweet with the fresh fragrance of Aicao, a green spring vegetable, In celebration of Qingming, people from Shaanxi make steamed buns, known as Huamo, made into different shapes.     5     Some are for peaceful family life while others represent the wish for health.

Last Sunday, my parents and I went to the countryside, which we had a great time together. To make it a green journey, we all agree to cycle there. With everything ready, we set out. Upon arrival, we got down to making preparation. Everyone was enjoying the pleasant but relaxing family atmosphere in open air. After the meal, my father and I couldn’t wait to fly kites. We watched our kites dancing high in the sky, laugh happily together. Mum couldn’t help cheering for them. Dusk fell down before we realized it. Seated together at ease, we quietly watched the gold setting sun, wishing to have more joyfully weekends like this.

4 . On the evening of April 8, Dunhuang Academy and Huawei jointly launched a brand-new technology-driven tour experience at the Mogao Grottoes. Using Huawei's newly-released Hetu artificial intelligence platform, coupled with the output of the Digital Dunhuang project, visitors to the Mogao Grottoes can enjoy a fantasy experience prior to entering the attraction.

Zhao Shengliang, director of the Dunhuang Academy, said that it has been cooperating with Huawei since March 2019. Using Huawei's latest Hetu technology, visitors are able to see the detailed contents of the Dunhuang Art Murals(壁画) outside the caves, through their Huawei mobile phones. This will reduce the time tourists spend inside the cave, aiding the protection of the cultural relics, while at the same time helping to increase the amount of information visitors can obtain. It is also considered to be a new way of promoting Dunhuang Art.

The Dunhuang Academy has used digital technology to preserve the research and exploration of Dunhuang Grottoes since the early 1990s. It has collected a wealth of data and has realized the goal of sharing of digital Dunhuang globally. It has played an important role in the protection and research of cultural site, as well as promoting the development and progress of related work.

The Huawei Hetu platform unites Dunhuang's study findings, high—resolution images of the site's murals and virtual, three-dimensional models with the real Mogao Grottoes. It has not only re-created the real tour of the scenic spot, but also developed a new way of digitally experiencing the grottoes. When people visit the site, they not only have the experience of seeing the real grottoes, but they can appreciate the admirable artworks more clearly and in greater detail.

In the future, Dunhuang Academy will continue to cooperate with Huawei to create more colorful virtual content to enrich the experience of Mogao Art on the platform, helping people around the world get to know Dunhuang Art better.

The Mayan civilization was from a group of people     1     lived in Central America. The Maya people used a(n)     2     (write) language before Columbus came to the Americas in 1492 AD. They were good     3     art, building, and math. They knew about stars and planets, which helped them make calendars.

The Mayan civilization was the most important between the years of 250 AD and 900 AD.     4     (gradual), the Mayan civilization spread all the way from Central Mexico to Honduras, Guatemala, and northern El Salvador.

The Maya people traded with other people in the Americas. They made changes to their buildings to make them much     5     (good). The style in which they made     6     ( they) buildings was often similar to styles of buildings in countries that the Maya people traded with.

The Mayan civilization started getting smaller after 900 AD. The Spanish arrived in     7     15th century and took over Central America, even in the Mayan areas. However, the Maya people still live there today. They even keep the old Mayan traditions and     8     (believe).There are many Mayan languages still spoken today,     9     (include) one called the Achi language. A play called Rabinal Achi     10     (consider) very important to the world.

6 . America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while—then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily, but truly can’t manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes,

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for pure business matters. So accept their hospitality at home !

7 . It warmed my heart today to walk into the Thirsty Camel downtown in the Thanksgiving Day, for a quick lunch before a haircut and library trip. Ilan, a food shop owner, said that he was refusing to take money today because it was Buy Nothing Day. To increase awareness(意识) of the stranger’s over-spending nature of our society, Ilan suggested a trade（交易）for food today. He simply asked that you offer something of equal personal value for the meal you received.

At first I was really uncomfortable, wondering if it would be fair(公平的) to exchange a yet to be determined “I Owe You” (IOU) for food? What could I give him of equal value? After all, his food is the best in the town!

We ended up writing our IOU’s with promises in a lot of ways if he needs it, such as a book, some paintings and the offer of work. I think the idea isn’t that the trade is “equal” so much as the importance of the kind of transaction. We put thought into our offer and we had an even greater understanding for the meals we ate.

We don’t buy a lot, especially at this upcoming time of year. We don’t give gifts at all in fact. The holiday time is spent enjoying each other’s company and doing things together with family and friends. This is what seems most sensible（明智的）.

Ilan is a good person. We are all lucky to have someone like this in our community.

8 . When you go to a foreign country, you often enter a new culture. The differences between cultures may make you feel stressed and you often find it difficult to adjust to the new surroundings, which is usually called “culture shock”.

The psychological and physical symptoms of culture shock may appear depending on the individuals. Some often feel anxious while adjusting to a new culture—even more so when the cultural distances are wide.     1     They remain to homesick and feel so sad about being separated from their friends back home that they long to return, especially within the first year.

    2    People adjusting to a new culture often feel lonely because the language barrier makes it hard to create new relationships. Furthermore, having trouble with the native language often makes them unwilling to interact with other people.

    3     You may do some research on the cultural aspects of the new country such as the history, customs, and religious beliefs, rather than on what to see and where to go, so you may get prepared for a culture that is different from yours. Studying the language is also a great way to help bridge the gap between the cultures.     4    

A local club provides the perfect environment to get to know people who have a similar focus, so join one so that you can meet some locals and develop new friendships.     5     There are other travelers who have the same experiences in a foreign country. Talk with them, sharing feelings, tips and insight.

9 . There are many expressions with the word “dog”.

    1    They take their dogs for walks, give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, lead a dog’s life, describes a person who has an unhappy existence.

When we say we live in a dog-eat-dog world.    2    A person has to work hard like a dog to be successful. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.

Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life.     3    Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new skills and will not change the way they do things.

Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as junkyard dogs living in places where people throw away things they do not want. Junkyard dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad.    4    

Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year.    5    But we do not want it to rain cats and dogs.

10 . If you look on the Internet, you will see that almost every day of the year celebrates some kind of food. These “holidays” have become very popular across the United States. They give people a chance to enjoy something they might not eat normally, like National Onion (洋葱) Ring Day, for example. Food holidays also give restaurants and other businesses a chance to promote their products.

But where did these American “holidays” come from? Many are the invention of an Alabama man, John-Bryan Hopkins. He writes about food for his Foodimentary. com website. Hopkins told Time magazine that when he began his site in 2006, there were only 175 “holidays.” “I filled in the rest,” he said.

The National Day Calendar has a list of all the different food and non-food related “holidays.” In the past, the website used to let anyone create their own day—for a price. But now, the site only accepts requests from businesses and other organizations.

While some food “holidays” are indeed made-up, many have historical roots. For example, National Beer Day on April 7 marks the end of a U. S. ban on the production, transport, import and sale of alcoholic drinks. The ban lasted from 1920 until 1933.

The Salvation Army, a Christian group, launched U. S. National Doughnut Day on June 1, 1938. It was meant to honor women who served soldiers doughnuts during World War I.

But not everyone likes food holidays. Bethany Jean Clement is a food writer for the Seattle Times newspaper. She wrote, “I get that some people might be excited by, say, National Doughnut Day. But you really can have a doughnut any day you want!”

Tavi Juarez, also of Foodimentary. com, thinks national food holidays are here to stay. She told the Seattle Times, “In my modest opinion, I believe that food holidays will continue to grow in popularity online because there’s a lot of negativity (消极) out there. Why not choose to celebrate food instead?”
