January 27,in order to win the new pneumonia Resistance War(抗击新型肺炎战). Ministry of Education asked to put off the start time of school in spring 2020.

However, many parents are very worried that putting of the start of school may affect children's studies. If they have such a long winter vacation. children will not learn any knowledge, read books or study at all. They may forget what they have learned before Staving at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.

In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice. that is, to organize online teaching and create a network platform(平台), where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.

It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection(感染) of the disease, but also make them study at home, improve their learning ability, and truly achieve "no suspension of classes". Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.

Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.

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.
