When you are on a long road trip or in a traffic jam during a daily-commute ， it may seem harmless to connect your phone to your car's USB port．But unless you really need to use your phone，charging(充电)your iphone during your commute could be a big mistake．

    Why? For starters，the USB port in our car probably provides less electricity than your phone really needs to charge．As a result，your phone might stop working while it charges.

    Many people may notice that on their way home from work their phone charged very little during their 30-60 minute commute，"says Brad Nichols，an engineer at Staymobile．"It is mostly because that the phone is using more power than the car charger isproviding it．"

    Nichols also says that your phone could receive too much power，especially if you are using a cigarette lighter port to charge up．Most cigarette lighters can provide more power than most chargers can afford．If a charger cannot keep providing the proper power, it may make the phone broken．

    Charging your phone could do harm to your car's battery(电池)，too．This usually isn't a big deal for those who own new cars with healthy batteries，Nichols says．But if your car is older，you might not want to charge your phone through its USB port．

    Most importantly，it's not safe to use your phone while driving．"Anytime a person's hands leave the wheel or eyes leave the road，it becomes dangerous for them and the other people around them," Nichols points out．Bottom line：Play it safe，and wait until you get home to charge your phone．

    Tea does not mean the same thing to everyone. In different countries people have different ideas about tea-drinking.

    Chinese people drink tea at any time of the day at homes or in teahouses. They prefer their tea with nothing else in it. The Japanese way of having tea is very old and full of meaning. There is even a special room for tea-drinking in Japanese homes. In England, almost everyone has a cup of tea in the late afternoon. The English usually make tea in a teapot and drink it with cream and sugar. They also eat cakes and cookies with tea. Americans usually use tea bags to make their tea. It's faster and easier. They drink tea mostly for breakfast or after meals. In summer they drink cold tea or iced tea.

How to Develop a Good Parent and Child Relation

The relation between a parent and a child is the most important in a child's life. It can make a difference to the child's life much. Positive relations can help children grow healthily and successfully. Here are some ways to help you build a good relation.

Get used to their way. If you learn more about their ideas and opinions, you will communicate or play with them in their way. This will help you get close easily. You can communicate with them freely and find the world in their heart through playing games on the floor instead of at the dinner table.

Make good use of family time. You must make family time a regular (有规律的) and special part of your life. Then your children can know you accept and respect them. You can eat meals together most nights of the week. You can also share sports events, movies and other events.

Join in children's school. If you have some free time, volunteer in the children's school. Then you can know more about your children at school. You can also sit near them when they do homework. This will make them better at schoolwork.

Build trust. It's important for you and your children to believe in each other. You can make them know they can trust you. When you plan to do something, you must finish it. You will set a good example for them.

Listen to children. If children are complaining (抱怨) about school, you must listen to them. Then they will know you are important and trust you. You also need to leave your mobile phone and TV and look at children's eyes. Then you can give your opinions and ideas to them in time.

Dark tea has a long history of being carried on horseback to China's northwestern areas as well as abroad. But as the fashion for new﹣style tea swept China，dark tea found new fans in big cities，mainly thanks to the thousands of bubble tea（珍珠奶茶）

In Changsha，the capital of Hunan，tea shops mix dark tea with light cream and pecans and advertise its health﹣improving effects（胆固醇）. "I like bubble tea but I don't want to get fat，so I'm interested in the health﹣improving effects of dark tea，"said Peng Hongzhi，a 37﹣year﹣old Changsha resident. Peng notes dark tea is famous for its bitter（味苦的），which causes a challenge to developers of popular drinks. 

Sexy Tea is a popular tea brand also known as the Modern China Tea Shop. It said it began to develop dark tea﹣based drinks in 2019 to diversify（使多样化） its products of green，black and olong teas. The company chose dark tea with richer flavors and added cream to improve the taste. 

"Dark tea has a strong personality. Some people love it，but some hate it，"said Liu Qiaofang

Liu Yang，the founder of Chaermasi Chinese Dark Tea，is one of the young businessmen working on dak tea. "We want to introduce dark tea into the lives of young Chinese in a more fashionable manner，who has opened four shops that use dark tea to make bubble tea and fruit tea. 

As a newecomer to the new﹣style tea market，dark tea drinks have few successful examples to draw experience from，so Liu's team mixes the tea with fruit and dried orange peel to increase its health benefits. "Luckily，"he said，expecting a growing number of health﹣conscious（关注健康的）

Do you know this place of interest? It is Guqintai (古琴台) in Hubei. It is in memory of (为了纪念) Yu Boya. 

Yu Boya is good at music and he is famous for (因. . . 而出名) playing the qin. But he is always unhappy because he thinks no one can understand his music. On the night of one Mid-Autumn Festival, Yu is playing the qin on a boat. When he finishes playing it, he hears someone's word, "I can feel high mountains and running water in your music. " It comes from a man, Zhong Ziqi. Yu invites him to the boat, and talks about music with him. He is quite surprised at Zhong's deep understanding, and he thinks Zhong is his "zhi yin". When Zhong leaves the world, Yu breaks his qin. Nobody will understand his music, Yu thinks. 

From then on, when people meet a true friend, they say they meet a "zhi yin".
