Mountain climbing is a popular activity during the Double Ninth Festival. This year, 【小题1】 festival coincides (同时发生) with our National Day Holiday. People are taking the opportunity 【小题2】 (enjoy) nature and pay their respects to their elderly family members.

A climbing competition was held on the “Great Wall” section outside the city of Chengdu on Tuesday.

Guo Tianqi, 【小题3】 comes from Chengdu, said, “Our forefathers climbed mountains on the Double Ninth Festival to drive away bad luck. This custom has continued through the centuries, but today, people do it more to keep fit and enjoy the beautiful autumn scenery. ”

“Double Ninth” in Chinese 【小题4】 (sound) like “a long time”, so it’s also known as the Senior Citizens’ Festival and a blessing (祝福) for the elderly to live a long and healthy life.

Guo competed with a group of retired (退休的) people 【小题5】 (join) the climbing competition, but exercise has made the word “old” 【小题6】 (complete) irrelevant (不相关的) to them.

Besides 【小题7】 (competitor), on the day of the Double Ninth Festival, many tourists also choose to get closer to nature and traditions with their relatives and friends.

Visitor Zhou Zhou said, “I want 【小题8】 (I) son to learn and experience our traditions in real life, rather 【小题9】 reading about them in books. I believe climbing can help him better understand our 【小题10】 (tradition) culture.”

The moment Fatima Bennett had dreamed of was finally here. Therefore, she couldn’t be 【小题1】(happy).

The 4C Challenge (also known as the Clark County Coding Competition) was the event of the year 【小题2】target participants were STEM-minded eighth graders like Fatima and her two best friends, Julia Sheen and Felipe Alvarez.

Their classmates were busy posting pictures on social media of their glorious summer vacations while the three best friends, who called 【小题3】Team Java Time, had spent countless hours storyboarding, coding, and adjusting their program. Their app, Romeo and Juliet Remixed, turned the famous play into a multiplayer adventure that retold the story,【小题4】(integrate) Shakespeare’s language with the rhymes of songs.

The completed app was due by September 1, and the teens had worked hard to get it done.【小题5】at any point they lost momentum (动力), they were pushed by weekly texts from Neil Green, who had taken over the competition coordination (协调) this year.

On the day when their app 【小题6】 (submit) to the competition’s submission website, Fatima said, “A prize would be great, but we all know the very best reward.” The teens shouted, “K-J-H-S!”

Fatima, Julia, and Felipe were excited to show off their digital skills in front of the other teams of eighth graders, but they were most interested in the reward 【小题7】(give) to the top three teams: guaranteed admission to Katherine Johnson High School, the county’s STEM magnet school. Felipe, Fatima, and Julia, friends since kindergarten,【小题8】barely contain their excitement. Their dream of going to KJHS together was 【小题9】their reach!

That was 【小题10】Fatima didn’t mind getting out of bed at 8 A.M. on this cold November Saturday to spend the day at Clarksville University, the site of the annual competition.

More than half of former host cities for the Winter Olympics will be too hot【小题1】(deal)with such games by the end of this century. That is the prediction of a recent study.

It's not just the Olympics that【小题2】(be) at risk now. “The world of winter sports is changing as the global climate continues warming,”says Daniel Scott,【小题3】climate-change researcher in Canada. He led a team of researchers,【小题4】used math to predict how winter conditions will have changed by February 2050 and 2080. February is the month when the Olympic winter games are【小题5】(typical) played．

Scott and his team forecast temperatures and snow cover for the 19 cities that have already hosted Winter Olympics, and two【小题6】(addition) cities: PyeongChang, South Korea，and Beijing, China, where the 2022 Winter Olympics will be held.

Scott’s team【小题7】(start) with looking at historic winter conditions, and then used computer models to predict conditions in the future.【小题8】( they) model predicted that by2050，the average February temperatures in past Winter Olympic host cities will rise by 1.9 【小题9】2.1 degrees Celsius. These temperatures can affect the quality of snow, thus【小题10】（increase)the chance of accidents.
