In English-language news, when you read about "relations between Beijing and Washington", it actually means "relations between China and the US". That's how important capital cities are -they stand for the country. The capital city has many roles. It is home to the central government as well as a center for cultural and economic activities. However, capital cities usually have a large population, which can be a big problem.

In August, 2019, Indonesia said that it will build a new capital on the island of Borneo. One of the reasons for this is that Jakarta, the current capital, is overpopulated. In Jakarta, the traffic is heavy and the areas people live in are crowded. What's worse, the ground has been going down at an average rate of about 10 centimeters a year and in some northern parts the ground is already 2 to 4 meters below the sea level. Rising sea levels linked (关联) to climate change could make the problem even worse in the future.

Last century, Rio de Janeiro, the then capital of Brazil, was overpopulated as well. In 1960, the country moved its capital to Brasilia to solve this problem. People believed that if they moved the capital to a less-developed city, Brazil would have more balanced development. This turned out to be right.

Many capital cities are facing problems as they develop. Besides building a new one, maybe new technology can help solve some of the problems.

Beijing In 2015, China's government called for building "smart" cities and planned to turn Beijing into one of these cities. A new sub-center in the city's Tongzhou district will be the testing ground for this idea. "Smart" technology will be used to solve traffic problems, control air pollution and recycle garbage.

Tokyo The capital of Japan is working to make itself a "green" city. People are encouraged to plant trees on their rooftops. The city will use technology to recycle rainwater and turn a landfill into a forest.

Singapore Singapore is a city-state. It is using internet of things(物联网)technology to help save energy. In public housing, smart sensors (传感器) remind people of how much water and electricity they are using.

DNA is in every cell ( 细 胞 ) of our bodies except for our red blood cells. It stores the information your body needs to make you who you are. Your DNA is 99.5% the same as everyone else on the planet. The 0.5% that we don't share with everyone else is the bit that makes you different.

DNA is the mysterious code ( 神秘密码 ) of life. It not only decides your gender ( 性别 ) and appearance, but also tells you about your family history, as well as your relations with people in other parts of the world.

Last fall, 20 students at Coretta Scott King Young Women's Leadership Academy in Atlanta learned more about who they are through a DNA test.

During their life sciences class, the girls took samples ( 样本) from their cheeks and sent them to Living DNA, a UK—based DNA testing company. From the test results, they learned about their ancestry ( 祖先 ) and made real-world connections to their races.

Lizbeth Islas, 12, learned about her family's Central American roots ( 根,根源 ) from her mother, who is Guatemalan ( 危地马拉人 ). She expected to share DNA with 54% of Native American people, but she was surprised to ?nd that she also shared DNA with people living in Africa and Europe.

Elianed Guzman, 13, knew little about her family except that they were from Mexico. She was surprised to learn that she also shared DNA with people in China and Japan.

The girls gathered in small groups to wait for their results. Their reactions reached from confusion to surprise. The 13-year-old Amariah Caudle said she learned that "the color of your skin can't decide where you are from."

Diahan Southard, a manager from Living DNA, helped them understand the test results. "Does it change how you see yourself?" Southard asked.

"Now I know I have family from everywhere," said Jahtmya Phillips, 13. "Does it change how you see the girls around the table?" Southard asked. "We are all sisters," said Anike Akanni-Jenkins, 13.

Laura Pena, the school's class designer, said she hopes to add DNA testing to the school's ninth grade curriculum ( 课程 ) in the future. "This is not a lesson they will forget anytime soon," she said.

Hairstyle is thought to be a personal style choice.

However, some Chinese students are required by their school to have unified (统—的) haircuts, with short hair for male students and shoulder-length hair for female students. Some students don't like such hairstyles and have broken the rules in school.

A complaint letter by a middle school student in Fuzhou, Fujian province as well as the response of the local education bureau (教育局) to the letter has caught public attention. The letter has sparked (引发) public discussion on whether schools should control how students wear their hair.

In the letter, which was published recently on Fuzhou's 12345 website, the student wrote, “I think the so-called 'good purposes' of the school are wrong and I highly question whether this kind requirement really helps students to develop good habits and show good appearances," the student said.

The school told students that it is easy for teenage male students to pay more attention to beautiful female students, so the school wants girls to have simple appearances and develop their talents, the letter said.

"I think these words are a complete lie. How can you expect someone to have a colourful future if he or she does not know how to look attractive? Why does the school need to make all the teenage boys pay no attention to girls? Doesn't the school need more sexual (性别的) education?

"Teenagers should be colourful and different. Isn't it boring when people look back on their teenage years and can only remember ugly haircuts and same uniforms? Why can't the school give students a choice to be themselves? "

The Fuzhou education bureau wrote back to the student and said it proves that the writer is a good student with his own thoughts, courage and truth-seeking spirit. The schools ask students to have unified haircuts and wear uniforms because it is easy for teenagers to pay much attention to their appearances and little attention to their studies, the bureau said. Collectivism (集体主义) is very important for the country's development. Although the city has required students to have unified haircuts, schools can set different hairstyle standards that allow students to show their personal styles.

I was beginning to grow handsome. My coat was bright and black, I had one white foot and a pretty white star on my forehead. When I was four, Squire Gordon decided to buy me. Then Farmer Grey began to break me in.

Like all horses that have grown up, I had to wear gears (用具). The first is a bit and bridle. I hated wearing a bit in my mouth. It was horrible, like a metal finger between my teeth. The saddle was not so bad. One morning, my master rode me round the meadow. I was proud to carry him, and I soon got used to it. But I didn’t like the iron shoes. They were very stiff and heavy on my feet. But in time I got used to that too.

My mother told me, “There are good men like our master, but there are bad men too. I hope you have good masters. But remember; always do your best.”

Early in May, a man came to take me away to Squire Gordon's house, in the village of Birtwick. My new stable (马厩) was large and comfortable. There was a little fat grey pony next to me. His name was Merrylegs. And I also found a tall chestnut horse at the corner of the stable, quiet.

“That's Ginger," Merrylegs told me. "She bites. One day she bit James, the groom (马夫). She says no one was kind to her before. But James and John, our grooms, are very good to us, and Squire Gordon doesn't whip (鞭打) his horses, so I think she's going to like it here."

The next morning John took me for a ride. On the way back, we met Squire Gordon and Mrs. Gordon.

"Well, John, how does he go?” the Squire asked.

“Excellent, sir." John answered.

Mrs. Gordon said, "He's a beauty. Let's call him Black Beauty."
