Technology and digital development have changed people's living styles these years. People show all kinds of things on the Internet which1 their interests, such as good food, nice clothes and so on. Among all the activities, now showing2 steps is becoming more and more popular.

    People are finding it important to be in good health. To keep3, many people go to work on foot. When they are walking, the step counter app in4 phones can record how many steps they walk that day. After walking, some people show themselves off on WeChat. This can make them5 from each other and keep exercising.

    "This helps me to exercise much and keep a good habit," Miss Liu said. "I can also talk about

    6  to keep fit with my friends on WeChat. We are in the same group to encourage each other to keep exercising."

    Mr. Wu likes to exercise. But in the past he was7 lazy and didn't want to exercise every day. "After I use the step counter app, everything is different. Sometimes there are prizes for

    8walk more steps. I really like it," he said.

    "Walking is9 useful and relaxing way to exercise. Both the old and the young like it. "Mr. Wang, a10 teacher said.   "Recording the steps helps people develop a good habit of walking   and showing the result can inspire people to be more interested in walking.

    "How can I improve my English?" A lot of my students have been asking me about this same question again and again.1 the answer won't be suitable for everyone, I'm still going to tell you some of my experience. I hope that you will improve your English learning skills.

    One thing I can tell you is that, once you start learning, you should try to think in English as

    2as you can. If you see something when you're riding your bike or walking down the street, just3"How would I say them in English?" At first, you may think with simple words but later with longer sentences. Now I'm in America, and for4the time, I would think in English and   speak it directly. It's amazing how much this helps.

    When I started learning, I was5 afraid of talking with others in English because I didn't want to make mistakes. Finally, I had a chance to6. And while traveling in America, I'd try to hang out with American friends,7 I'd have no choice but to speak English. Also, I decided if I said anything stupid and other people would look8 me, then so be it. After that, my English started to9 much more quickly.

    Besides, it may be a good idea to ask your American friends to look at the way you're writing, and give you some10 for improvement.

    Has anyone ever told you that eating carrots will help you see in the dark? This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let's take a look.

    Can eating carrots improve your eyesight?

Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places. However, eating more carrots won't help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.

    If your parents have bad eyesight, will you have bad eyesight, too?

Myopia( 近 视 ) can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there's a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it's down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.

    Do color blind people see the world in black and white?

Color blindness doesn't usually mean that people see the world like an old movie. They usually can't tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue. Our eyes have cone cells (视锥细胞) that sense different wavelengths of light. If these cells don't work properly, color blindness occurs. There are different levels of color blindness. Some people are only color blind in low light. However, in the most serious form of color blindness, everything is shades of gray.

    How did Chinese people choose the 12 animals of the zodiac (生肖)?

    There are many stories      the Chinese zodiac. In one of the most       stories, the Jade Emperor (玉皇大帝）wanted to pick 12 animals to keep his palace safe. He ordered all the animals to have a       to run to the palace. The first 12 animals to       at the palace were the winners. They then became part of our calendar.

           , the real history behind the Chinese zodiac is much harder to find. Some say the zodiac came from animals       were important in people's lives at the time. Some of the animals were   ones that people      at home, such as the chicken and the pig. Others were animals they loved such as the tiger and the monkey. Others say that ancient Chinese people chose the 12 animals according to animals' habits. This is because people not      used the zodiac to stand for different years, but also used them to tell time.

           animal stands for one shichen, or two hours. It is said that during each shichen, its corresponding (相应的) animal would be active. For example, the mouse stands for the period of time from 11 pm to 1 am      this is the time when mice would go out to look for food. Do you think our ancient Chinese are full of wisdom(智慧)?

    Li Hua is not alone. There are some students like him. According to a survey about Li Hua and his classmates, students have four main problems when they are homeschooled. First, 30% of the students have problems getting along with their family. Second, 25% of the students have difficulties managing their time. And 28% find it hard to full themselves together to work on their subjects. Last but not least, 33% are dependent on playing online games or watching videos.

    However, there is always a solution to a problem. Take communication problem for example. Huang Li has discovered a new way to understand her mom. "Don't keep your eyes on your phone for a long time" is actually saying "I am worried about your eyes"; "Have you finished your homework?" means "I hope you can be your own master in study." Huang Li says our parents love us. If we can really get the true meaning of what they say, we won't find it so hard to listen to them.
