Science and technology can be seen everywhere. They are making our life more convenient(方便的) and comfortable. Some scientists recently added amazing ideas to four common things and made great changes to them.
It’s not just a phone. China has taken the leading place in several scientific fields. In February, 2019, Huawei introduced Mate X, the first 5G phone that can be folded(折叠) in the world. It allows users to read e-books or watch movies on a larger screen. The Mate X supports(支持) 5G. It means you can get a movie from the Internet about 100 times faster than using 4G. |
They are not just chopsticks. Scientists at an American university have invented a pair of electronic chopsticks that can change the taste of food. When you put the chopsticks in your mouth, they can make you feel the taste becomes better, such as making sweet food taste sweeter or salty food less salty. Soon the scientists are going to try their technology on bottles, cups and spoons(勺子). |
It’s not just a sticker(粘贴). It’s said that about 52% of the fruits of the earth go bad before reaching the buyers. Scientists from Malaysia(马来西亚) thought of a simple way to solve the problem — tiny stickers that are made out of some natural materials(材料). Put the stickers on fruits, and the fruits can keep fresh up to two weeks. |
They are not just shoes. Every step you take is helping cut down air pollution. This is not in science fiction(科幻小说). A team from Europe has invented such a pair of shoes. The shoes can take in dirty air and send out clean air. If you wear the shoes and walk one kilometer, the shoes can clean the air polluted by eight cars. |
1. The first 5G phone that can be folded in the world is from ________.
| A．China | B．Germany | C．Malaysia | D．America |

【推荐1】Do you want to have a birthday party 140 kilometers above the ground, or have a dance weightlessly (失重地) with your friends? Just wait for a few years.
A new business space company in China started to develop a kind of new spaceship in 2017. People with enough money may be able to go on space journeys about ten years later.
Han Qingping, the president of China Rocket Corporation (公司), said the company would develop a kind of spaceship that can take three to five travelers. It can reach a height of 80 km above the ground. The height is right in the top part of the mesosphere (中间层), higher than planes and balloons can travel, but just below the height where satellites (卫星) fly. There travelers will have a new way to watch the mother planet and they can experience weightlessness as well.
Tang Yagang, a head of CALT’s space activity department (部门), said China Rocket Corporation will offer four types of rockets to the market. They can meet different humans’ activities. Now scientists are working hard to make it true and it is certainly that people’s life will be more colorful in the future.

【推荐2】Computer scientist Mary has an idea for a new robot to help her work with children. How should it look? The robot should have arms to be able to lift things. And if it is going to communicate with people, it will also need a face. Scientists believe that giving a robot a face can make it seem more friendly. Humans would also like to pay more attention to robots with faces. But what kind?
For Mary, she wants to make sure that her new robot doesn’t look too much like a human. She wants people to just treat it as a machine-person. If it looks more like a human than a machine, she thinks users might find it a bit creepy and feel afraid. Mary also believes that robots’ faces don’t need to look a lot like ours. Her research shows that we can enjoy communicating with robots whether or not they look like humans, because our brains are able to look for faces. Just put two circles on top of a robot’s body, and we will see a face.
Dave feels differently. He believes that although at first we might be afraid when seeing a robot with a lifelike face, we may soon get used to it. If robots are going to work closely with humans, they should look as much like us as possible. After all, faces are an important part of the way we communicate.
To make his robots look as much like real people as possible, Dave invented a special skin (皮肤) for their faces. With this skin, robots can show human-like expressions and appear to be angry, sad, happy or surprised. Dave’s robots are also programmed to copy expressions. How? Just imagine his robot is looking at you. The cameras in its eyes send pictures of your face to its central computer!

【推荐3】Bi Sheng was born in the Song Dynasty. He lived in a small village which lies in Huanggang today. He invented the printing around 600 AD. He is the world’s first inventor of the printing. It is about 400 years earlier than the printing in Germany.
The printing is also called the movable type printing (活字印刷). But how did it work in the past?
First of all, the clay was made into movable types. Then words were engraved carefully onto the types. After that the words were chosen and put in right order in a box according to the text. Next, the workers brushed ink onto the movable types. Finally, the types could be used for printing. They could be used again and again for different books.
The movable type printing plays an important role in Chinese culture. With the help of it, Chinese culture spread around the world more quickly. At the same time, the movable type printing was widely used in the world at that time. As a result, more and more culture communication among countries took place.
The movable type printing, the compass (指南针), gunpowder and the paper-making are called “Four Great Inventions of Ancient China”. They make China own an important and even top position in the history of human civilization (文明).

【推荐1】A smartphone can make your life so much easier and fun. But it can be a problem, too. When you drop your phone and break the screen (屏幕), it’s expensive to fix!
One scientist is working hard to fix this problem. Wang Chao is from the University of California, Riverside in the US. He is building a new material (材料) that can fix itself. Wang said he got the idea from popular X-Men character Wolverine. The superhero can heal (治愈) himself.
The new material is self-healing, too. It is very stretchy (有弹性的). When it breaks, it can go back together again in 24 hours, like human skin (皮肤). This is called chemical bonding (化学键接). “So when you drop your cell phone, it could fix itself and last much longer,” Wang said.
Wang told other scientists about his idea at a meeting in April. He hopes his new material will be ready for smartphones to use in less than three years.

【推荐3】What’s going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.
Digital money
We used to pay with cash(现金) for everything we bought. Now when we use a credit card(信用卡) to shop online, money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it’s hard to live without them. It’s reported that people in Sweden completely stopped using cash last year, and the US might be next.
Bionic(仿生的) eye
It’s no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data(数据) to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution(高清的) image could be just a few years away.
Self-driving cars
Unlike a human driver, a self-driving car won’t get distracted(分神) by a phone call, the radio or something outside the window. Sensors(探测器) and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself. In the future, driver-less cars would be widely accepted.
1. ______ has stopped using cash completely.| A．Sweden | B．ATM | C．BBC | D．America |
| A．We use digital money to shop online without paying money. |

| A．Bionic eyes only appear in the science fiction film. |
| B．Human drivers won’t get distracted by something outside. |
| C．The blind wearing bionic eyes may see clearly in the future. |
| D．There will be no road accident at all if self-driving cars are used. |
| A．culture and Art | B．industry and farming |
| C．science and technology | D．traffic and journey |

【推荐1】Traveling can be expensive. But there are some ways to save money when traveling. Try some of the advice below on your next vacation and your wallet will thank you.
Look for city tourism cards. With the card, you can pay less at restaurants and shops. You don’t have to wait for a long time at busy attractions. You might even get free tickets to top tourist attractions. City tourism cards can save your money and time without question.
Don’t get the best room. How long will you stay in your room? Will you just be sleeping there?
Do you really need a bigger room with a good view (景色)?
Find a hotel outside a city. It can help you save some money by choosing a hotel away from big tourist attractions, for you are always doing the same — go to the attractions and then return to your hotel to sleep.
Book (预订) a room with a kitchen. Although some people might not like to cook while on vacation, I don’t mind making breakfast in my room. We always eat at a nice restaurant on our last night of the vacation. I’d rather eat breakfast and lunch at the hotel and then spend much money on a delicious supper.

Under the Dome, a 103-minute documentary by former news reporter Chai Jing, was released on video-sharing websites in China on Feb 28. It has rapidly pushed the public attention about air pollution and encouraged people to join in efforts to make a difference.
Chai, 39, said she started the work out of her “personal clashes” with smog( 雾霾)after she gave birth to her daughter, who got cancer when Chai was pregnant. “I closed all the windows. I started every day by checking the air pollution index.” Chai said. Millions of other people are also doing the same. While they stop there, Chai goes deeper. “I don’t want to live in this way. I need to find out where the smog comes from and what on earth is going on.”
Over a year, she examined polluted sites to find the sources(根源) of smog, visited the US and the UK to learn about their experience of preventing pollution, and interviewed officials, scientists and the general public. Chai’s research finds that the burning of coal and oil helps to bring about 60 percent of PM2.5 pollutants. So she questions the country’s energy consumption(消费) habits in the film. The film also points at China’s petroleum(石油) and steel industries as the biggest sources of air pollution. Chai goes on to list the things common people can do to help protect the environment.
The film has caused national discussion after going online. Some pictures of withered trees, grey skies and babies under treatment because of bad pollution have moved many people. But most importantly, the film looks at solutions that the government and each person can carry out to help.
Cheng Chen, a 22-year-old student from Beijing University, found the documentary “very inspiring”. “I used to think it’s not my duty to deal with air pollution–I don’t own a factory or a car,” said Cheng. “But Chai told me we share the same fate(命运) since we breathe the same air and there is a lot I can do.”

【推荐3】Do you know that in some parts of the world, people build temporary (暂时的) hotels made of snow and blocks (大块) of ice? These are known as ice hotels.
Unlike usual hotels, all the rooms in the ice hotels are made of ice. In some ice hotels, even the glasses for drinks are made of ice blocks. So they only serve cold drinks. Also, hot food is not served in the ice hotels, but guests (客人) can eat hot food at places nearby.
To keep warm, guests sleep in comfortable sleeping bags on ice blocks that are covered by mattresses (床垫) and reindeer skins (驯鹿皮).
There are some places in the ice hotels that are heated, such as the bathrooms. This is because, even though it is not as cold in the ice hotels as it is outdoors, indoor temperature is still very low.
Perhaps the most interesting thing about the ice hotels is that they are rebuilt every year.They can be used only during the winter months. The ice hotels melt (融化) away when spring arrives. The ice blocks used to build these hotels are from nearby rivers. So, when the ice hotels melt away, they melt back into the rivers.
1. Which of the following about the ice hotels is true?| A．They are just like usual hotels. | B．The glasses are made of wood. |
| C．They serve cold drinks. | D．The rooms are made of bamboo. |
| A．Guests want to eat in them. | B．Indoor temperature is very low. |

【推荐1】Traveling is not always happy, at least for the buddies in the movie Green Book. The popular film won Best Picture at the 91st Academy Awards on Feb 25.
The movie was adapted from the true story of a road trip through the southern US in the early 1960s.
In the film, the black pianist Don Shirley hires Italian-American Tony Vallelonga to drive him to performances, but they face problems because of Shirley’s skin color. These problems lead them to form a special friendship.
“There’s something so deeply right about this movie, so true to the time,” wrote US film critic Mick LaSalle.The time LaSalle is talking about was between late 1870s and 1960s, a very different period in US history. Many parts of the country had Jim Crow laws (《吉姆·克劳法》), which allowed racial segregation (种族隔离). These laws made life and travel 39 for African-Americans. They couldn’t use certain hotels, restaurants, or even gas stations. They had to be indoors after sunset or they might be put into prison. Even black celebrities (名人) had to follow the laws.
But in 1936, a black mail carrier named Victor H. Green had an idea. He made a list of friendly businesses in New York City. He published the list as a small book with a green cover. The Green Book helped African-Americans travel more safely. Then, in 1964, Jim Crow laws went away. The book went away, too.
Today many US people still remember the time of Jim Crow. But they probably don’t know about The Green Book. It’s a forgotten part of the story. Thanks to this movie, maybe people can remember it again.

Eat and drink properly
What is healthy to eat in summer? Fresh and light food. Fish can be a good choice. It can keep your body energetic and help fight against the burning sun. Another good choice is colourful fruit and vegetables. They not only lease our eyes, but are full of healthy chemicals(化学物质). Tomatoes can help protect your skin against sunburn. Blueberries are good for your brain and eyes. The more colour, the better!
With all those summertime activities you will be thirsty. What to drink? Water. Water has zero calories(卡路里) and is the perfect drink to stop your thirst(口渴). Try not to drink too many energy drinks, sports drinks and soda drinks which have lots of sugar and caffeine(咖啡因) in them.
Stay active and cool
Summer is a great season to enjoy outdoor activities and play. It's also a good time to lose weight. If you are lucky enough to be near a body of water, try water sports like swimming, surfing, water skiing and so on. These sports keep you cool and active at the same time. You'll have no problem beating the heat and keeping fit as well.
Be careful of the sunshine
Summer allows us more chances to get outside, but it also means more possibilities to get burnt by the sunshine. If you are going outside, keep away from the sun when it's the strongest—usually between 11 a．m. and 3 p．m. If you have to stay in the sun for a long time, sunscreen(防晒霜), a big hat and a longsleeve jacket will be necessary.
