Mr. Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code(二维码). “We spent an hour or two in class learning how to generate(使产生) the codes, and in the end everything gets easier ,” said Guo, “
“The paper is not easy to keep, but the code is easy to keep and share,” Guo said. “It is worth trying to use new technology in education. Education itself is a kind of creation.
However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the codes when they hand in their work, which doesn’t take them too much time.
| A．The QR codes can be sent to Mr. Guo by e-mail, QQ and WeChat. |
| B．But some students don’t like WeChat or QQ. |
| C．Also for teachers, it allows them to check the students’ work at any time. |

| E．When students finish the homework, they keep it on WeChat. |
| F．I don’t want my students to fall behind the times. |

【推荐2】The Hexa Plant is a six-legged robot that has been specially made to care for the potted (盆栽的) plant that it carries on top of its head. Using light and heat sensors (传感器), the robot has the ability to carry its plant in and out of the daylight. If the houseplant needs more sun, the Hexa will walk into the sunlight; if the houseplant is getting too hot, the Hexa will go back into the area that blocks direct light. The Hexa Plant will even do a little dance when it senses that the plant needs to be watered to warn its owner.
The robot was developed by the Vincross engineer and founder Sun Tianqi after he saw a dead sunflower siting in the darkness in a room back. “Plants only receive an action without responding,”Sun Tianqi wrote in a blog post. “Whether they are being cut, bitten, burned or pulled from the earth, or when they haven’t received enough sunshine, water, or are too hot or cold, they will hold still and take whatever is happening to them.”
According to Sun Tianqi, for billions of years, plants have never experienced movement of any kind, not even the simplest movement. In their whole lives, they stick to where they were born. Sun Tiangi continued, “Do they want to break their own settings or have a tendency (趋势) towards this? I do not know the answer, but I would love to try to share some of this human tendency and technology with plants. With the help of the robot, plants can experience the move.”
The Hexa Plant model robots are not for sale, though Vincross does sell a Hexa robot model. It is said that in the near future the robots can open up a new market to watch over our household plants.

【推荐3】Ping-Pong Door
Do you want a ping-pong table in your room? But you may not have enough space. Now this door is here to help you. It can turn into a ping-pong table when you pull it down. After the ping-pong game is over, it goes back to being a common door. It was designed by Tobias Fränzel from Germany. Cool idea!
Dog Watch
The dog watch is actually a “clock for keeping time at a rate(比率) other than human time” and was invented in 1991. With this handy(便利的) watch, you can know time at your animal's rate instead of your own. According to the inventor, the watch multiplies(乘) every human second, minute and hour by seven, giving us “doggy time”. If a dog lives to be the age of 14, that translates into 98 human years!
Earthquake House
Big earthquakes can hit a house, possibly making the people in it get hurt. But our inventor has found a way, the Earthquake House!
His idea is simple. Build a round house that has earthquake sensors(传感器) in it. If the sensors know the big earthquake, the house will be free from its chains(链条). Don't worry. You always remain upright in it. We don't recommend this for a hillside home because there aren't any brakes to stop it!
Smell This
How do you know if your breath smells nice, or if it smells bad? It's difficult to know because it's very hard to smell the air that comes out of your own mouth. Smell This is useful for this situation. You just place the mask on your face, then breathe out through your mouth and breathe in through your nose.
1. If a dog lives to 5 years old, that translates to ________ human years.| A．25 | B．30 | C．35 | D．40 |

【推荐1】When it comes to Chinese students considering studying in foreign countries, many of them usually believe that life will be easy and enjoyable. Unfortunately, it’s likely that students with those thoughts will be disappointed very soon after landing at the airport.
So, what are the problems you may have, and how can you deal with them?
Teaching and learning styles in America are very different from those in China, requiring more critical thinking（批判性思维）and teamwork. In a normal American classroom, one project might be done by a study group in which every person has their own responsibility.
So don’t worry about your language or any grammar mistakes. Just watch what other students do, and don’t be afraid of asking any questions. The discussions, or sometimes even arguments, that your group members and you hold are likely to be the beginning of a friendship.
Besides schoolwork, another important thing faced by overseas students is homesickness or loneliness. You may miss your parents’ cooking, your pets, especially when faced with the challenges of getting used to a new environment.
What I strongly suggest is to try hard to deal with these feelings. Be open to new friendships. Sign up for school activities, and give yourself permission to enjoy life at school, even if you miss home a lot. Be organized and keep a diary to check your progress. Write down three new things that you’re thankful for every evening as well as three things you are looking forward to every morning.
Studying abroad is never simple. In fact, there will be many difficulties every day. But I’m sure you will overcome your difficulties and make your time overseas a success.

【推荐2】Should Children Be Allowed to Get Bored?
Children need time to stand and stare. They should be allowed to get bored to that they can develop their ability to be creative.
Children are expected by their parents to be reading a textbook all the time. However, research shows that it may hamper the development of their imagination, while boredom can give them opportunities to develop creativity.
Boredom is often linked with loneliness, but a writer named Meera Syal said boredom had helped here in developing her mind. She told researchers about her childhood. Having few things todo, Syal often talked with her neighbors. She also tried to do things like learning to bake cakes. “But importantly, I Thought and wrote a lot, because I was bored,” Syal said. She kept a diary, filling here time with short stories and poems she made up.
Grayson Perry, an artist, grew up in a family with little money. He enjoyed himself by making up stories, drawing pictures for his stories and reading many books in the library. Bored but free, he spent hours looking out of the window, watching the changing clouds and seasons. Perry filled up his free time with what he liked. He became creative, because he could think freely.
Dr. Belton is an expert on the effects of emotions on learning. “Boredom could be an uncomfortable feeling,” she said. “But some young people cannot deal with that boredom creatively. So sometimes they may break a classroom window, or drive a car out for a mad race.”
Usually, when children have nothing to do, they would turn on the TV, the computer, or the phone. Their time on these things has increased, yet they need to have time to think about their experiences through play or just watching the world around them.
It is this kind of thinking that can inspire the imagination. On the other hand, the TV or phone may cut short the thinking process. That can be harmful to the development of creativity. “For developing the ability to be creative,” Dr. Belton advised, “perhaps we need to stand and stare, and stay off-line from time to time.”

【推荐3】Li Yongle is the kind of teacher that most students love. He is funny, smart. Most importantly, he believes math and physics are not just tools to explain knowledge on textbooks. They also deal with something important, from romance to aliens.
How to find your Mr. Or Mrs. Right? What is COVID-19? And where exactly are all the aliens? Everything seems to be covered in Li’s short videos on the Xigua video app. Li has more than 11 million followers. The 37-year -old man has been teaching physics for 11 years at the High School Affiliated to Renmin University of China in Beijing. He tries his best to find more information behind hot topics with distrustful eyes and a sense of humor.
Since 2017, he has posted over 400 videos. When China launched Tianwen-I, which is the first independent Mars mission in China, he posted a video to explain how the launch date was chosen, and what is considered the best route from Earth to Mars. “I am not Mr. Know-It-All. I just reproduce and reorganize the knowledge in books or online. After that I present it in an acceptable way to help people better understand the world,” Li said, and the Internet provides a good opportunity to achieve equal education for all.”
To further improve equality（平等）in education and science education, Li plans to record basic classes in high school. So he does that with some other science video creators who are active on the app. They post the videos on the platform for free.
