【推荐1】Most people may think that people who write computer code (代码) must be good at math and logical (逻辑的) thinking. However, people who write computer code say that creativity is also important for writing code.
Software developers (开发者) in the USA have created a game called Osmo Coding Jam. The game is designed to help children use the creative side of their minds as they learning to code. Children can play the game on iPads.
Tanya Dodge is the mother of two children who play the game. According to her, these activities give them important skills for the future. “It's an analytical (分析的) skill” said Dodge.
But the developers believe writing code should be more than just an analytical skill. “We want to explore the creative side of coding that I think is often not as explored,” said Felix Hu, an Osmo engineer. Hu added, “The coolest part is that we're teaching kids how to be creative with code and that's a really important thing that kids should get comfortable with because coding is creative.”
Hu also sees many parents who feel that software code is a second language that children need to learn to succeed in future jobs. Tanya Dodge agrees, she said, “I think you're going to have to understand at some point the idea of coding will work well in the future.” Hu also explained that very often kids grow up not understanding how a computer works or just thinking that it's like a magical machine. He said by breaking it down to a lower level, kids can understand that the computer isn't as smart as they think it is.

【推荐2】Reading and writing doesn’t come naturally to people. Although it takes some effort, eighty-six percent of the world’s population have learned how to read and write, and the number has been increasing for centuries. Literacy(读写能力) makes it possible for us to navigate the world filled with books, websites, text messages, road signs, and more. But the world of information is changing. Why send a long letter or text when you can share photos or videos instead? Why learn from a book when you can learn from a video? Why read magazines when you can listen to podcasts(播客)?
Could people join today’s world without the abilities of reading or writing? ____△____ Most of our devices(设备) now talk to us and take spoken orders. Smart cars ask for where you go and then give directions. Smart virtual assistants, like Siri, listen for requests to report the weather, play a song, set a timer and much more. Some apps can also read text aloud or turn speech into text. These devices aren’t perfect—the apps still make silly mistakes. But they’re getting better and better. So in the future, it’s possible that all of our communication with our devices and each other is spoken.
But reading and writing are powerful tools. For one, most people read faster than they speak. A podcaster speaks at around 150 to 160 words each minute, while a strong reader can look through a text at 300 to 400 words each minute. That’s twice as fast! Research has also found that when people read, they can remember more information and stay more interested than when they listen. Learning to read also creates new connections in the brain. With the invention of reading, our brain has been changed, which developed the ways we were able to think, which changed the intellectual evolution(智力进化) of humans. Would we really choose to give up that progress?
What do you think? Do you hope people keep on reading and writing, or will technology make literacy useless?

【推荐3】On the morning of May 30th, 2019, Huawei helped the BBC use 5G to report news. It was the first time that 5G was used in the world! Actually, China just began to use 5G in June 2019. What’s the most special about 5G? 5G lets us send and receive information in a very short time. Now, 4G takes about 100 to 200 milliseconds(毫秒) to send and receive information. But 5G will help the time down to 1 millisecond or less. The big change that 5G brings will not only make our mobile network faster, but also deeply change our lives in many ways.
First, 5G can connect with amusements. 5G is about 100 times faster than 4G. This means you can download a movie in seconds by using 5G. Also, VR games will become more popular with 5G. 5G will make people feel the games even more real.
Second, 5G can connect with traffic. 5G will also make self-driving cars safer. These cars can send messages to each other. They also “talk” to traffic lights and road sensors(传感器). 5G will allow self-driving cars to have faster reaction(反应) than human drivers.
Third, 5G can connect with smart homes. 5G also makes the IOT possible. IOT is a large network that connects everything to the Internet. Smart homes are part of it. Smart homes can make the machines automatic. For example, if the sensor feels the floor becoming dirty, a smart floor cleaning robot will sweep the floor by itself. And your bread maker could start making breakfast ahead of time or before you get up.
Although not everyone can use 5G networks now, China is trying its best to let everyone use 5G as soon as possible!

【推荐1】Scientists in Japan have developed electric chopsticks that are designed to help people cut down on salt. Though human bodies need salt, many people eat far too much of it, which is unhealthy. It’s well known that eating too much salt can lead to high blood pressure, heart disease and so on. The special chopsticks use a tiny bit of electricity to make food seem saltier than it is.
Kirin, a Japanese company that sells food and drink, worked with researchers at Miyashita Laboratory to develop the chopsticks. The chopsticks have a battery pack that can be worn on the wrist (手腕). When the tips of the chopsticks are put in the mouth, a very light electric current (电流)—too small to be felt as a shock—changes the way the tongue (舌头) tastes certain chemicals.
Experiments showed that with the chopsticks, food could have up to 30% less salt and still taste just as salty. So far Kirin hasn’t announced plans to sell the chopsticks. But it is looking into ways the technology could be used with other eating utensils (餐具), including spoons.

【推荐2】“Four great inventions” in ancient China are important symbols of the country. Now China has “new four great inventions”: high-speed trains, mobile payment (移动支付), bike sharing and online shopping. They are changing people’s lives in China and maybe all over the world.
High-speed trains
By the end of 2016, China had the world’s largest high-speed railway network (铁路网). More than 2,500 high-speed trains are running across China each day. Lin Jinlong, an overseas student from Cambodia shared his experience of traveling by Chinese high-speed train from Beijing to Tianjin. The two cities are over 100 km away, but the trip took only about half an hour. “That was amazing!” Lin said.
Mobile payment
Mobile payment has become a part of Chinese people’s everyday life. It makes their lives much more convenient (便利的). “My wallet is no longer in use. Download some apps in my smart phone, I can buy and eat anything I want simply with it,” said Lin. “Even vegetable sellers are using mobile payment.”
Bike sharing
Bike sharing is not new itself, but the bike sharing in China is special—it allows users to pick a bike anywhere in the city and leave it anywhere at the end of their Journey. It’s really convenient, cheap and green. Mobike, a bike sharing company, has even brought the service to some other countries.
Online shopping
You are out if you have never shopped online. Now you can buy almost everything from websites like Taobao and JD, and get what you’ve bought within days. China’s online shopping makes many foreigners feel both excited and surprised.

The growth in skyscrapers (摩天大楼) worldwide, most of which have large glass panes, has led to a great need for window washers. Though the job, which earns workers as much as $35 an hour, can be lucrative, accidents are not uncommon. However, the dangerous chore may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.
Much like humans, Ozmo, hanging off the sides of the building, uses its arms and brushes to clean the dirt and grime on the glass panes. A 3-D map of the building programmed into its system allows the robot to skillfully move up and down. Computer vision and touch sensors (传感器) enable it to move out of the way in case of unexpected events, such as the sudden opening of a window. And the robot will self-correct and move around it so as not to break a window.
Unlike other window washers, the robot cleaner does not require soap or Windex to clean the glass. Instead, it uses purified water (纯净水) and a process called reverse osmosis (反渗透) to do the job. It is environmentally friendly.
While it takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers, only making their jobs safer. Human workers will control the robot from below.
Whether Ozmo, which is still undergoing testing, does as good a job as humans remains to be seen. * Past efforts to use a robot to do this dangerous job have not been successful, because the machines do not have the same eye as humans and often miss the soot (烟垢) collected on window corners.
1. The underlined word “lucrative” in the passant’ probably means “________”A.安全的 | B.危险的 | C.赚钱的 |
A.why Ozmo is much more intelligent than human workers |
B.how Ozmo works to clean the glass smartly |
C.what makes Ozmo an intelligent window cleaning robot |
A.Purified water. | B.Soap. | C.Grime or soot. |
A.560 | B.400 | C.1,360 |
A.As an intelligent window cleaning robot. Ozmo is successful. |
B.Ozmo does harm to the environment while cleaning the window. |
C.Ozmo can make human window washers do their jobs safely. |

China plans to send one to three network backup satellites for the BeiDou Navigation Satellite System(BDS) into space this year to improve the stability and usability of the constellation(星座), according to the 13th China Satellite Navigation Conference on Thursday, April 27, 2023.
Beidou is a positioning system. It is developed by China. China is the third country in the world to have its own positioning system. With Beidou, China no longer has to depend on foreign systems. This is very important for national safety. Work on Beidou began in 1994. However, the first two Beidou satellites, were not sent into space until 2000. Currently, it has 45 satellites in orbit(轨道), including 15 for BDS-2 and 30 for BDS-3. These satellites have formed a global network.
The complete Beidou will be more powerful than any existing(现存的) positioning system all over the world. Yang Changfeng is a designer of Beidou. He says that the system can notice the sway(摇摆) of a building in strong winds. Beidou has brought many advantages to our lives. Let’s take Shanghai as example. Thousands of buses have been using Beidou. When we are waiting for a bus, we can know when it is about to come. Many smart phones have been using Beidou as well, “Many people say, let me turn on my GPS. In fact, their phones are using Beidou.” jokes a salesperson in Beijing.
China will accelerate (加快) the integration(融合) of BDS with emerging technologies such as 5G, artificial intelligence and big data. It aims to build a more ubiquitous, integrated, and intelligent national spatial and temporal system by 2035.
The 3-day conference kicked off Wednesday in Beijing. More than 4, 000 experts and scholars from home and abroad in the satellite navigation field attended the conference online and offline.

【推荐3】The First Lesson of “Tiangong Classroom”
Three astronauts-Zhai Zhigang, Wang Yaping and Ye Guangfu opened the first lecture of Tiangong Class. The courses introduced several interesting experiments. It encouraged people to explore the science and love the space industry. Let’s take a look at these experiments.
Experiment 1 | ☑A paper flower made on the earth is put into the space water ball. When the paper touches water, the water quickly enters into the paper. Paper takes in water and expands (膨胀), which will gradually flatten the creases (压平折痕) and create a “flowering” effect. |
Experiment 2 | ☑After putting a ping-pong ball into the water cup on the ground, it is floating (悬浮) because of buoyancy (浮力), but in space, when the ping-pong ball is put into the water cup, it “sinks (下沉)” and stays in the water, This is because buoyancy appears with gravity (重力). In the weightless (失重) environment of space, buoyancy almost disappears. |
Experiment 3 | ☑An effervescent tablet (泡腾片) is put into a blue water ball. Most of the bubbles (气泡) produced by it stay in the water ball and turn into a bubble ball, like a blue earth. Inside the space station, the bubbles are not affected by buoyancy. Most of the bubbles remain in the water, while a few break through the surface. |
1. What was the meaning-of doing these experiments?
A.To help people travel into space. |

It was a cold and cloudy afternoon at the end of winter. I put on my hockey pads, picked up my bag and ran towards the car. My heart was racing because I was getting ready to try out for the Boston Junior Team.
“Dad,” as we drove, I said, “I’m really nervous. Will I make it?”
“You’ll do fine, Emily,” he said to me comfortingly. “I know what kind of player you are. No matter what, give your all.”
“OK,” I answered.
When I arrived at the rink (冰场), I greeted some friends who were also trying out. I tied my skates and carefully stepped out onto the ice. After a while, we were divided into two teams, and the match started. I tried to stay focused but still felt nervous. I messed up a few times. Sometimes I passed too early, took a bad shot, or didn’t make a play I probably should have. I felt like my skates had minds of their own, but I remembered what my dad said: I should give my all. I kept trying to make the best play possible. My dad’s words pushed me to keep going.
After the match, some players were pleased, while others seemed to be in the same situation as me, feeling like their playing was awful. I got home and told my parents that I didn’t think I would make the team, and I went to sleep without dinner.
As I was eating breakfast the next morning, my mother, to my surprise, walked into the kitchen with a wide smile on her face.
“The coach just emailed me. You’ve made it!”she said excitedly.
I was so relieved (如释重负) and shocked at the same time. I got up and hugged her, then read the email for myself, still unable to believe it was true.
That day, I realized that I may not be the most talented person there, but if I try my hardest, I can do anything.
