Each year, on the 15th day of the seventh month in the Chinese lunar calendar, the Ghost Festival is celebrated all over Asia. On this day, it     1     (believe) that the gates of Heaven and Hell open up,     2     (allow) the spirits of all the dead to visit the Earth. During this time, people will burn offerings (祭品) and prepare fancy meals     3     (pay) respect to the dead.

Similar holidays are celebrated all around the world. However, these holidays tend to be less gloomy (阴郁的)     4     Chinese holidays. In the Western world, Halloween, Oct 31 every year, is mainly celebrated by     5     (light) pumpkin lanterns and dressing up in costumes (服装). It is considered     6     a time to remember and honor the dead. The Day of the Dead is celebrated in Mexico on Nov.1&2 each year. People will build altars (祭坛) at home and decorate them with candles, flowers, skulls (骷髅头) and gifts. Around the altar, people pray and tell stories about the dead. This holiday is also     7     (joy). In some public areas, there are even parties at night.

Death is a     8     (frighten) thing. But holidays like these can help us to better understand death as a natural part of life,    9     can remind us to value our own time on Earth and encourage us to live our best     10     (life).

You are twenty-one years old and live a happy and peaceful life.    1    one day, your doctor tells you that you have a serious disease and will die soon. What would you do?    2    (probable) most of us might feel very sad and give up our dreams and hopes for the future. Here is    3    the great scientist, Stephen Hawking, did.

Hawking wasn’t discouraged because    4    his physical condition. Instead, he went on with his study of the universe. In 2002, Hawking    5    (invite) to China. He told Chinese students about his theories and    6    (think) on some of the greatest questions: what is time, how the universe began, and what are black holes. Stephen Hawking impressed the audience    7    (he) humor, confidence and of course wisdom. In 1988, Hawking,    8    (know) as a physicist, wrote A Brief History of Time, which was a tool for    9    (spread) scientific knowledge. The book has been selling well since it came out.

Stephen Hawking is a man with a strong will and he is regarded as the    10    (great) mind in physics since Albert Einstein.

China’s science fiction is now at the best of times, compared to the old days. In 1999,     1     Wu Yan taught at Beijing Normal University, he started a course on science fiction. It was     2     first time such a course came into a comprehensive university (综合，性大学) in China. He later set up a master’s degree program in 2003 and a PhD program in 2015. In 2017, Wu     3     (go) to work at Southern University o£ Science and Technology in Shenzhen, where he founded a research center for science and human imagination     4    (focus) more on his study. All     5    (he) actions pioneered toward popularizing science fiction in China.

Pushed forward     6     the outstanding works from various writers, it is     7     (real) obvious that science fiction has now jumped out of its small pond into the wider public sea.

^“Science fiction is the weathervane (风向标) of a country’s     8     (develop) Liu Cixin said. China’s future might     9     (fill) with challenges, which meanwhile might provide science fiction with plenty of authentic subject matter and     10    (end) imagination. He added, “China’s science fiction is entering its golden age.”

Cecilia Chiang, who had brought real Chinese food to America, died at 100 at her home in San Francisco on Wednesday. In the 1960s, her restaurant, the Mandarin,     1    (introduce) Americans to       2    variety of real Chinese dishes.

Ms.Chiang came to the United States     3     China as a daughter of wealth. Once in San Francisco, she managed     4    (bring) Chinese dishes into the ones which are     5    (tasteful) than before.

The Mandarin offered specialties at the time, like Chongqing-style spicy beef, peppery Sichuan eggplant and glacéed bananas. These were     6    (tradition) cooking of the rich in Beijing, where local dishes as well as regional(地区的) ones from Sichuan, Shanghai and Canton     7     ( prepare) by family chefs.

Ms.Chiang’s father was an educated railway engineer. Her mother came from a wealthy family     8     owned factories.     9    (grow) up in the family, she did well in every aspect of her life. After her parents died, Cecilia Chiang took over the businesses     10    (successful) .

“I think I changed what everyone knows about Chinese food,” Mrs. Chiang told The San Francisco Chronicle in 2007. “They didn’t know China was such a big country.”

Close to 70 percent of the world’s population will live in cities by the year 2050. Experts warn that population     1    (grow) will worsen housing crises in some areas.

Large cities around the world already struggle with housing problems. In some neighborhoods, rising house prices have forced     2     poor from their homes. Many poor people now live in shelters or on the street.

People     3    (move) to large cities now not just for high-paying jobs. Many are also looking for the chance to live and work with other people, career opportunity and access to much     4    (good) resources. Some countries have built new capital cities     5    (help) ease overcrowding. These efforts help, but do not solve the problem.

The report says that by 2030, the world will have had 43 very large     6    (city), each with more than10 million people.

Tjada McKenna,     7     is chief operating officer for an aid group, says that the ability to own a home in many countries is often difficult,     8    (especial) for women and minority groups.

Every city is different in     9    (deal) with development problems. Each one has its own economic forces at work and its own history. Experts say that answers     10     the housing crisis and other problems must be developed city by city.

Science experiments can help you to understand the reason behind anything and everything. As we grow up, we get to know many things which we would be     1     (astonish) to see as kids.     2     (make) a kid understand the difference between magic and reality, you need to show him the science behind it. You will not face any difficulty in doing so as they are always eager to know about it. It is a basic human ability to remember things which he     3    (watch)and does by himself. Hence(因此)practical exercises are very important for children in their daily life.

Few things you should keep in mind while     4    (select) the experiments for kids. The     5    (much) important thing is to take a simple concept. If the concept is too difficult,     6    will be difficult for children to finish that experiment. So you should select simple experiments which are right for their age. The other thing is that you need to choose     7     experiments which are not poisonous and with easy    8    (equip)and that can be handled    9    (easy)by your kids. Child's safety should be your priority(优先考虑的事情). I am going to give you some science experiments     10     will help you to make these small kids understand simple facts with complete safety in my next article.

A few months ago I left my hometown for Canada to study. I felt nervous because I was going to     1     new place with new people. What worried my at first was that I couldn’t speak English     2     (fluent), and I also couldn’t understand     3     (they) customs. Everything was different     4     my own country. I had to deal with everything alone.It was a sad moment     5     I had to say goodbye to my family and friends at the airport. Suddenly, I felt unwilling     6     (leave) my hometown because I grew up there and had wonderful     7     (memory) of the familiar place. However, I know studying abroad was a     8     (decide) that I made myself. I had to accept the challenge. By now I     9     (get) used to the new life here already, though I’m looking forward to     10    (spend) the coming vacation with my old friends back home.

Australia was always a country I wanted to visit so I saved up some money and     1     (take) the plane for Australia at     2    end of the school term.

It was strange when I arrived. It was the start of winter! Happily for me the weather was still hot and sunny though.     3     also took me a while to get used to the time difference.

The country is     4    ( true) beautiful, full of wildlife you wouldn’t find anywhere else in the world. I visited a koala sanctuary (考拉保护区) in Brisbane —- there were koalas everywhere     5     (sleep) in the trees and I even got the chance     6     (hold) one. I learnt lots of     7     (fact) about koalas, too. For example, koalas can sleep for up to 22 hours a day. At the sanctuary there were also kangaroos (袋鼠) that we     8    (allow) to feed. They were really cute and friendly.

Another exciting part of my trip was snorkelling (潜泳) in the Great Barrier Reef, as the water was very clear and blue. I was also lucky to see some     9    ( interest )sea animals.

I loved visiting everywhere from the beautiful mountains and waterfalls in the National Parks     10    the long white sandy beaches. It’s a beautiful country and worth visiting one day if you ever get the chance.

The 21st century is dominated by more technology-oriented inventions than before. The 20th century     1    (see) man land on the moon. The 21st century will witness man landing on several planets. The first will be Mars, also     2    (call) the Red Planet. As planned by NASA, the mission can be achieved by 2030. That will set a precedent(先例) for explorations by future generations. Furthermore, increased investment in research is likely     3     (lead) to the discovery of a vaccine for AIDS.

Technology is advancing fast. Social media at present acts as one of the leading 64.    4    (source) of news and interaction,     5     has a negative influence on traditional media,     6    (particular) print newspapers. Social media will soon take over the market.

Mobile phones will play a greater role     7     the purchase of goods, as well as the withdrawing and depositing of money. Electronic money will replace paper money. In addition, with declining oil reserves across the world, electric cars will replace petrol cars in a few decades. As     8     result, there will be a major shift in job trends.

Global warming will become an even     9    (big) problem, with sea levels     10    (continue) to rise. Freshwater sources will be polluted. Fresh water will become a major issue. Hence environmental destruction will increase greatly.

As a five-year old girl, Lin Qiaozhi was deeply affected by her mother’s death. At the age of 18, instead of following the    1     (tradition) path of marriage, she     2     (choose) to study medicine.

Eight years later, Lin graduated with the Wenhai Scholarship, the highest prize     3    (give)to graduates. She became the first woman ever to be hired     4     a resident physician in the OB-GYN department of PUMC Hospital     5     (immediate). Within six months, she     6     (name) a chief resident physician, a position that usually took four years     7    (achieve). After working for a few years, she was sent to study in Europe and then in the US. She greatly impressed her American colleagues,     8     invited her to stay. Dr Lin, however, rejected the offer.

The new People’s Republic of China saw Dr Lin playing     9     key role. She was always responsible for the     10     (patient) and treated them as her sisters. She was known as the “mother of ten thousand babies”.
