With over 1.4 billion people, China has the world’s largest population, but one of the smallest surname pools. In contrast, the United States    1     (report) to have 6.3 million surnames in its 2010 census (人口普查). So what is it    2     leads to this vast difference?

It’s    3     (part) because of the difference in language. You can’t just add a stroke (笔画) to a Chinese character and create a new surname. Technology is also a factor at play. We rely on technology on    4     daily basis. The systems that process our information rely on a    5     (limit) list of standardized Chinese characters,     6     means that those with rare characters in their surnames may find using this technology difficult. It causes them    7     (change) their last names out of convenience. Meanwhile, the    8     (lose) of certain surnames over time is a naturally    9     (occur) phenomenon. Given China’s long history, it has lost more names over time, compared to younger countries.     10    , this phenomenon is still one that Chinese people are struggling within the digital age.

When Michael Jordan’s feet left the ground, time seemed to stand     1    . The player who became known as “Air Jordan” changed basketball with his     2     moves and jumps. Jordan’s skills were impressive, but the     3    strength that he showed made him     4    . In the final seconds of a game, Jordan always seemed to find a way to win. Jordan says that the secret to his success is     5     from his failures. “I can accept failure; everyone fails at something. But I can’t accept not trying.” Losing games taught him to practise     6    and never give up. In life, Jordan has learnt to share his success with others. The Boys and Girls Club     7     he started in Chicago has been young people since 1996.

At the beginning,     8     Chinese was a picture-based language. It dates back several thousand years     9    the use of animal     10     and shells on which symbols were     11     by ancient Chinese people. Some of the ancient symbols can still be seen in today's Hanzi.

By the Shang Dynasty, these symbols had become     12    well-developed writing system. Over the years, the system developed into different forms,     13     it was a time when people were divided geographically,     14    to many varieties of dialects and characters. This,     15    , changed under the Emperor Qinshihuang of the Qin Dynasty (221-207BCE).

Internet is a sea full of all kinds of information. I don't think those passages or comments     1    are shared popularly make me lost. In a way, I think the phenomenon can bring some advantages.    2    (first), those passages or comments usually can arouse us the same feeling. For example, one year ago,     3     passage about recalling the childhood life of 1990s     4    (share) crazily on the Internet. Almost everyone was very moved after reading it. After all, it's one part of our cherished     5    (memory). Secondly, those information shared can help us think better.     6    (face) so much information shared on the Internet, as long as we don't believe it     7    (blind), we can learn something good from those comments, then add something original and creative     8    our own. I believe it's even    9     helpful and beneficial for our thinking ability. Anyhow, with the     10    (develop) of technology, we should learn to keep a tolerant attitude to adapting the new trend.

6 . While reading the newspaper, I saw a picture of poor people living in one poor area. I called my best friend and I________ going to that place, choose any house and give them all that we can buy, like food. She liked the ________ and we decided to go next week.

We bought something that may________ dinners for two weeks. After arriving there, we knocked ________   one door. A young girl around six years old ________ the door. I asked, “May I see your mom or dad?” She ran inside and________ with her mom in a few minutes. I will ________ forget her. She looked sick and ________.

“ We came to ________ you,” I said. She smiled and said,"Please come in." It was ________.They were living in a cold room without any furniture, and they just sat on a piece of cloth on the cold________.

“How do you ________ ?” my friend asked. The woman said,
“I'm sick with cancer and these are my two ________. My husband left for three months to bring a heater for us,________ until today he didn't come back.”

We gave them the stuff, and we ________ to come and visit them every month. In the ________ at visit we brought some sugar, rice, tomatoes, potatoes and some meat. We bought a carpet and some blankets besides the ________ for them. The kids looked so ________ each time they saw us.

I kept doing that until I left that ________ to im migrate to Canada. I still________ the little girl. She always said to us, “Please come back again.”

7 . Grandpa moved in with us after Grandma passed away. He came to Canada from China, where he was a well-respected school headmaster.

I, a nine-year-old boy, never spoke much Chinese. Grandpa didn't speak much English, but we still connected in our own way.

One way we developed our relationship was over a game of Monopoly. He didn't really understand the rules or much of what my little brother and I said; I don't think it mattered. He laughed when he landed on our hotels. Or when he pulled a card that read: “GO TO JAIL.” He got a kick out of our amusement.

I think of Grandpa when I play the trading card game Yu-Gi-Oh! with my sons. I can't keep track of all the spells and effects involved in this game.

Truthfully, I don't care if I win or lose these games. What matters is spending time with my children and making an effort to understand their interests.

I often think about my kids. At how excitedly they explain rules and how they go easy on their old man. I imagine it's like how Grandpa felt playing Monopoly with us.

Grandpa went for regular walks. He also spent his days sitting on the couch, staring out the window and singing quietly. I often thought he was bored. But as I age, I find peace in taking moments to stare out a window. Maybe I got that from him.

What I learned from my grandfather was to enjoy simple pleasures in life. To see the beauty in the colors of the rainbow. To see a single leaf fall from a tree. To play Yu-Gi-Oh! with my sons.

Festivals are celebrated all around the world. They have a wide range of origins, such as the seasons of the year,     1    , famous figures, and important events. Every festival has     2     different customs and unique charms. However, no matter     3     different they may seem, all over the world, the spirit of sharing joy,     4     , love, or peace is common in all festivals.

    5     all the traditional festivals, the harvest festival can be found in almost every culture. This important     6     festival takes place after all the crops have been gathered in. People celebrate to show that they are grateful     7     the year's supply of food. In ancient Egypt, the harvest festival was celebrated during the springtime-the Egyptian harvest season. It     8     a parade and a great feast with music, dancing, and sports. Today, in some European countries, people     9     churches and town halls with flowers and fruit, and get together to celebrate over a meal. During the Mid-Autumn Festival in China, families gather to admire the     10     moon and enjoy delicious mooncakes.

9 . Humans don't know why the environment shapes the gender of some lizards, crocodiles and all kinds of sea turtles.

Sea turtle eggs thathatchbelow 81.86 degrees Fahrenheit produce males, according to the National Oceanic and Atmospheric Administration, while nests in the mid-80s create a gender mix. Anything higher than 87.8 degrees, though, is 100 percent girls.

A 2018 study on green turtles near Australia's Great Barrier Reef found 116 female hatchlings for every male. The study found that 99 percent of hatchlings from the warmer northern beaches were female while the share in the cooler south was much lower (69 percent).

NOAA researchers determined the gender gap in Australia started widening after the early 1990s,when the temperature started climbing. Female turtles that hatched before that period were more than males by a smaller rate-6 to 1.

A 2015 report from San Diego also showed a change after years of hotter nesting seasons: Sea turtles tested on the southern California shores had gone from 65 percent to 78 percent female.

And researchers at Florida Atlantic University guess that hatchlings on Boca Raton's beaches these days are at least 90 percent female.

Scientists have been testing methods to cool the nests. Gently digging up eggs and moving them to shadier parts of the beach has proved to work. So do sprinkler(洒水) systems and dividing eggs into smaller hatches.

Once replanted, the hatchlings burst from the ground some 50 days later in 1-by-1-foot area, moving in circles until someone puts them into a wooden box and carries them to the shore, where they climb into the waves.
