【题目】 In the space of just two years, the app Douyin, created by Beijing-based company ByteDance, has gathered more than half a billion users—around 40%of them outside China—who share short videos of themselves lip-syncing( 假唱), cooking, dancing or just being silly. What sets ByteDance apart is its success in the social media category, which is controlled by Facebook, Twitter and Snap—all Western companies.

ByteDance calls itself an artificial intelligence company. It uses machine learning and algorithms ( 算法) to figure out what people like most and give them more of what they want to see. On Douyin, people can edit and beautify 15-second videos before posting them online. The app has even made a phrase to describe people glued to their customized feeds: “shua Douyin” or “scrolling through Douyin”. Last year, the company released TikTok, the overseas version of Douyin. ByteDance’s growing video empire has made it the world’s fifth biggest app maker. ByteDance says TikTok and Douyin together have more than 500 million monthly active users.

Investors like ByteDance because its hundreds of millions of users attract a lot of advertising money. The video apps are lucrative because they attract a lot of users in their teens and 20s, who are more generous with the money. ByteDance also makes money through income sharing deals. People on TikTok, for example, can buy digital coins to give to other people on the app—like throwing money in a performer’s tip jar. ByteDance takes a cut of those earnings.

ByteDance’s founder and CEO is Zhang Yiming, a 35-year-old former Microsoft employee. People who have worked with Zhang describe him as someone who thinks deeply about technology and spends much of his free time writing code.

Like Facebook and Twitter, ByteDance is also battling fake news and inappropriate content. ByteDance promises to add thousands more employees to review content on Douyin.

【题目】 In March, days before her 15th birthday, Ashima Shiraishi successfully climbed Horizon on Mt. Hiei in Japan. She became the first woman and youngest person ever to solve the “V15” boulder( 攀岩) problem, considered the most difficult type of problem in the sport.

Shiraishi is also the world’s youngest person to solve the V10,V13,and V14 boulder problem, which she did at ages 8, 10, and 13.

“Once I have a project in mind, I don’t really give up,” she said. “And even if my skin is looking really bad from bouldering, I’ll just get back on it.”

The New York City native first got to know the sport at age 6 when she saw park-goers climbing Rat Rock in a city park in New York City. Attracted, she started climbing it every day after school and began training at an indoor climbing gym soon after.

She won her first competition at age 7, competing against grown women climbers.

“It was mostly the movement that really attracted me because it was almost like dancing. It felt like I was dancing on the rock,” she said.

Watching Shiraishi climb is like watching a dance of mental and physical courage. At 5-foot-1 and 100 pounds, she could be considered at a physical disadvantage compared to taller climbers who can reach holds more readily. But she makes up for it with smooth movements that only a climber of small size could make.

“The most important part of climbing is not really thinking at all. Once you start thinking, you doubt yourself, and that’s the worst that could happen to you,” she said.

Shiraishi hopes to compete on the most important stage for sports, the 2020 Olympic Games in Tokyo, where climbing will make its first official appearance.
