I try to advise them to cycle to work, so I did some research about the benefits of cycling to work. Of course, cycling has some advantages over driving. It is cheaper, it is better for the environment, and you don’t have to find a parking space. The point about the parking space is an important one as the car parks are often full. I know that my workmate sometimes spends 15 minutes looking for a parking space! It is true that cycling is a little slower than going by car, but at rush hour it doesn’t make much difference. The time it takes to cycle is generally easier to predict than the time it takes to drive. When there is heavy traffic, people on bicycles can get past, while people in cars have to wait.
There are clear health benefits to cycling. According to one expert, if you cycle regularly you should be as fit as a younger person. I am 47 and I still play football in a team,so I would say that his opinion is true. As well as being good for your health, cycling can reduce stress. I also find that when I can’t solve a problem at work, the answer often comes to me when I am cycling. Sometimes the harder you think about a problem, the harder it is to find the solution. And you really need to pay less attention to the problems. Cycling relaxes the mind.
I am going to say to my workmates “two wheels good, four wheels bad” every day until they get on their bikes!

【推荐3】If you go to London, you can see a lot of buses and cars on the roads. You can also see many bikes because more people go out by bike. Why? There are many reasons(原因). First, it is very cheap to buy a bike. And then people often need to wait for(等待) a bus for half an hour. Finally, when the bus comes, there are so many other buses and cars on the road. So the bus moves very slowly.
I go to work by bus for about four years, I often arrive at work late and feel tired. One day, a friend of mine says, “I go to work by bike. Why don’t we go to work together?” “My bike is old. I leave it at my home for a long time. And there are so many buses and cars on the roads,” I answer. “Don’t be afraid. If you follow me and we ride slowly, you’ll be fine,” he says.
Later I buy a new bike. We ride slowly, but we arrive at work quickly. It takes me about 40 minutes to go to work by bus, but only half an hour by bike! Now I love riding a bike and I feel healthy. Many people think my idea is good and maybe you can see more bikes on the roads in London.

【推荐1】Kites have a long history. They may date back (追溯到) long time ago. They were made of bamboo and silk in China. Nobody knows exactly how or when a kite was first flown but it is said that when a Chinese farmer tied a string (绳子) to his hat to keep it from blowing away in a strong wind, the first kite was born.
Children like playing with kites. Kites for work or play are made of wood, bamboo, paper, or silk. In 478 BC, a Chinese philosopher (思想家), Mo Zi, spent three years making a kite out of light wood and bamboo. The earliest record (记录) of kite flying was in about 200 BC when the Chinese General Han Xin of Han Dynasty flew a kite over the walls of a city. He wanted to know how far his army would have to travel.
In the 13th century, Marco Polo wrote about how the shipping businessmen flew the huge kite in the wind before the ship set sail (起航). It predicted the voyage (航海) in this way. If the kite went high and starlight, it meant a quick and successful ride, but if it didn’t fly well, it was a bad omen (预兆). In the late 1500s, the kite was introduced to Europe by the Italians. Kite flying was first mentioned in England in a popular book in 1589.

Have you ever seen a solar panel（太阳能电池板）in your neighborhood? Solar panels take energy from the sun and turn it into electricity. Over the past ten years, the price of solar panels has gone down greatly. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power（给……供电）their homes.
However, solar panels also have their problems. They stop working at night and on rainy days. Is it possible to make them produce electricity all of the time?
Scientists at Suzhou University, China, have invented a new solar panel now. It can produce electricity not only from solar energy but also from falling rain. When a raindrop falls on the solar panel and then rolls（滚动）down, it creates friction（摩擦力）on the surface of the panel, which can then be turned into electricity.
Sun Baoquan is one of the inventors. “Our new invention can produce electricity in any weather during the day,” he says. “It can even provide electricity at night if there is rain.”
The solar panel, however, does not make much electricity from falling rain. So Sun Baoquan is still working hard to improve it. The scientist also wants to make solar panels more flexible, which are as soft as clothing.
The field of solar energy is developing fast. Scientists around the world have been improving solar panels. Some have been working on ways to join solar panels and wind power together. Some have been trying to use sunlight to produce liquid and gas fuels（液体和气体燃料）.

When Goldie Nejat began developing robots in 2005, she spent much of her time knocking on doors to let people know how her robots worked but few showed interest.
“But now, it’s different,” says Nejat. “People calling from around the world ask when my robots are going to be ready.”
Nejat’s robots are made to fill an increasing need: care-giving for the old. The population of the people over age 80 will be 426 million in 2050, three times larger than that now.
Some have worried that care-giving robots might make human interaction (互动) less and cause more humans to lose their jobs. “But the purpose is to support human care, not to replace it,” says Brian Scassellati. He has tested robots with different patients, and found that daily interaction with robots can help children with autism spectrum disorder (自闭症谱系障碍) improve social skills.
Well, of course, more robots have served the Beijing 2022 Winter Olympics. Cleaning robots can clean 8, 600 square meters of indoor large public areas such as staff area, athlete area and competition hall. And cleaning robots can adapt (适应) to large-traffic crowds and continuous (持续的) work. For those who are not wearing masks (口罩) in the area, reminding robots will come forward to remind them to wear masks. What’s more, delivery (配送) robots have entered the main media center restaurant, where each dish is made by robots. After the cooking is completed, the robots will take it to the ordering guests.
As a field grows, scientists try to understand human-robot relationships better. Do robots offer advantages because they don’t have feelings and don’t give opinions? “One thing is clear,” Scassellati says. “Many types of robots are quietly serving the people and the need for that will increase in the future.”
1. For what are Nejat’s robots made? __________| A．Knocking on doors. |
| B．Taking care of the old. |
| C．Working in Beijing. |
| D．Making phone calls. |
| A．代替 | B．忽略 | C．放弃 | D．帮助 |

【推荐3】What is 5G? It is the fifth generation of mobile network technology. China’s telecom companies have been able to offer 5G networks for mobile phone users since 2019.
Do you know the development of mobile network technology? Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G?
5G has a very short delay between sending and receiving information. 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less. This is almost real-time.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G+entertainment: 5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G. Also. virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G+transport: 5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors (传感器). 5G will allow cars to react even faster than human drivers.
5G+smart homes: 5G also makes the Internet of things (IoT) (物联网) possible. IoT is a large network that connects everything to the Internet. Smart homes are part of it. For example, your toaster can automatically start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
1. What’s the writer’s purpose in writing the second paragraph?| A．To explain 5G is the best of all. |
| B．To share his knowledge about 5G. |
| C．To encourage people to use the new network technology. |

Most people have map apps on their phones that can show their locations (位置) and guide them to where they want to go. But how do these app systems know your locations at any time or place? They find you by using satellite navigation (satnav) systems (卫星导航系统).
A satnav system uses groups of satellites to find the users’ locations. This location information is then sent to a receiver, such as a smartphone.
The first satnav system is the Global Positioning System (GPS) (全球定位系统), which belongs to the United States. The system is the world’s leading satnav system. But China’s satellites are important for improving the satnav system. BeiDou Navigation Satellite System (BDS), has overtaken (超过) GPS in size, Japan’s Nikkei Asian Review reported. China sent BeiDou’s first navigation satellite into space in 2000. China also built a satnav system after the United States and Russia, People’s Daily reported. Until now, over 30 countries in Africa and the Middle East are using BeiDou system.
With its world-leading technology, BeiDou is leading Chinese people to a better life by playing important roles in different areas.
1. Map apps can guide people to where they want to go.2. The users’ locations are found by groups of satellites.
3. The world’s first satnav system is the BDS.
