Over 5 million shared bikes in China are using services offered by Beidou Navigation Satellite System(北斗卫星导航系统). These shared bikes all use Beidou based positioning chips(芯片).
The chips have high qualities. They can deal with information accurately and quickly. They feature low power consumption. They provide a better user experience and easier management for the local companies. Now, several new models of shared electric bikes with Beidou-based chips have also started to be produced and put into market. Besides positioning and navigation, the chips will help users and bike companies record user speed and battery condition of an electric bike. The possible crimes during the bike using will also be recorded.
In fact, years ago, shared bike companies began to use positioning chips which worked well with both GPS and Beidou services. After the Beidou system became fully in use in the summer of 2020, shared bike companies started installing Beidou-based chips on more bikes in more areas. The latest chips which are popular with bike companies are smaller and have more advantages over the old types.
Since 2000, a total of 59 Beidou satellites have been lifted from the Xichang Satellite Launch Center in Sichuan Province. After the final satellite was lifted in 2020, the system was completed and started providing global services. Beidou Satellite System is designed and developed by China and it is one of four global navigation networks, along with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo.
According to a research in 2022, by the end of 2021the total value connected with satellite navigation and positioning services in China was 469 billion yuan, a 16.3-percent increase year-on-year. More than 500,000 Chinese people now work at around 14.000 China’s companies and organizations doing business connected with Beidou and other satellite navigation and positioning services.

【推荐1】It’s hard to refuse a delicious banana. They taste good and you don’t have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050.
One reason for this is climate (气候) change. Scientists at the University of Exeter collected numbers from 27 countries and areas that produce 86 percent of the world’s bananas. They found that climate change has improved growing conditions in 21 countries of these countries. In the past 60 years, the average yield (平均产量) has reached 1.37 tons of bananas per hectare (每公顷).
However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world’s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.
Shouldn’t bananas grow more easily if it’s hotter outside? In fact, the perfect temperature for growing bananas is between 24 and 32℃. If the temperature gets too high, they will stop growing.
Diseases are another danger to bananas. Unlike other plants, all banana plants have the same genotype (基因型). In other words, if a disease is able to kill one plant, it could kill them all.
1. What is the reason why bananas may disappear by 2050?| A．Climate change. | B．Produce less. | C．Same genotype. | D．Low temperature. |

【推荐2】Infrared thermometers（红外温度计）, or temperature guns, have been widely used to detect（检测）the early symptoms of COVID-19. They allow us to measure（测量）temperatures quickly. How do these thermometers work?
They determine temperature by measuring the energy coming from your skin （皮肤）. Everything in nature has molecules （分子） inside of it that are always moving around. This include our skin. The higher the temperature is, the faster the molecules move. The molecules give off infrared light while moving.
This kind of light can be focused or absorbed（吸收）. The thermometers use a lens（镜头）to focus infrared light from the skin onto a detector called a thermopile（热电堆）. The thermopile absorbs the infrared radiation and turns it into heat. The electronic sensors inside the thermometers can measure the heat and read the temperature of the skin after making some calculations （计算）.
However, you might sometimes find that the results aren’t always accurate （准确的）. It depend on how these devices are used. For example, how far away they are held from the body, how steadily they are held and for how long. Factors such as make-up and sweat will also affect the results.

A tsunami(海啸) is a very large ocean wave usually caused by an earthquake under the ocean. Most earthquakes happen where two plates, or blocks of Earth’s crust(地壳) come together. When the plates push against each other, one plate can snap up suddenly, sending out energy upward. The energy is then transferred(较移) into the ocean, causing a tsunami wave to rise and spread out in two directions. A tsunami can travel more than 600 miles before it reaches the shore. |

Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, chances and challenges come together.
Let’s start with the ways to get health care. Telemedicine (远程医疗) can allow a patient to use technology to see the doctor online and get a diagnosis and instructions without leaving home.
There are many online patient websites, which have different kinds of interactions (互动) about our health needs. Setting a date with doctors and reading results have been achieved by technology already.
A whole new age of medical care seems possible to come in the future. But every coin has two sides. What might be on the other side of techno-health care?
First, sharing the details of one’s health requires trust, which takes time to build. This is certainly true in health care, where some of life’s best and worst moments have something to do with doctors. The human touch is also very important for patients and is impossible to be there over the smartphone.
Second, test results can be difficult to understand. When someone without a medical degree sees a result with no explanation on the website, there’s room for all kinds of terrible stories to form in their minds.
So how does medicine get along well with the new technology age? Some talented companies are working on it. There is medical equipment that can be used at home to send necessary signs and heart sounds through telemedicine. It seems possible that some companies will find a way to explain test results.
But what it will not achieve is the touch and the warmth of human interaction. Patients often need someone to listen to and care about their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will probably have unexpected effects.
1. According to the passage, how does technology help health care?| A．It encourages patients to put their needs online. |
| B．It offers patients another way to get a diagnosis. |
| C．It allows more interaction between doctors and patients. |
| D．It provides patients a chance to explain test results. |
| A．Patient websites require trust from doctors. | B．Talented companies can give medical advice. |
| C．Online results may cause worry for patients. | D．Medical equipment can send signs to patients. |
| A．technology can deal with some unexpected effects |
| B．usual health care will be a challenge to telemedicine |
| C．techno-health care should consider about humans’ basic needs |
| D．it is difficult for patients to get used to the new technology age |
【推荐3】China now has more than 30,000 kilometers of high speed track, and this is expected to increase to 38,000 kilometers by 2025. Fully two thirds of the world’s high speed rail (by length) is in China. Here, we track the exciting technological developments in high speed rail and consider their cultural influence.
While the main advantage of the high speed rail lines is convenience for people to get from one city to another as quickly as possible, some of these high speed lines have become popular tourist attractions. A good example of this is the Hefei-Fuzhou high speed line.
Technically speaking, this was one of the most challenging high speed rail routes ever built; nearly 90% of the track was laid either on bridges or in tunnels. However, the breathtaking views are worth it, as the train go through some of China’s most beautiful mountainous areas, including the Huangshan and the Wuyi Mountain Ranges.
Now that China has gained skills and knowledge in high speed rail, it is trying to export(出口) its technology to other countries. Its first venture(项目) on the international market was the line connecting Istanbul with Turkey’s capital, Ankara, 530 kilometers away. This was followed by projects among other countries. Perhaps its most ambitious project is a Trans Asian network linking(连接) China with Europe. Although it is difficult, China will make every effort to take on this plan. It is hoped to be completed by 2030 as a part of China’s Belt and Road Initiative.
Thanks to high speed rail, the travel time between major cities in China has already been reduced to only a few hours. This convenience in turn should improve the development within and out of China. No doubt, it will also bring the people of the country closer together, and in time bring about deep social changes, the full nature of which no one can fully guess.

【推荐2】At 00:23 on Oct. 16, the Shenzhou XIII spacecraft rose into the sky. Three Chinese astronauts—Zhai Zhigang, Wang Yaping and Ye Guangfu—set off for the Tiangong space station.
During their six-month stay, they will set up robotic arms and do medical experiments, among other tasks. Wang Yaping will become the first Chinese woman to take a spacewalk.
It’s not an easy job to do all these things. Chinese astronauts get difficult training before going to space. As People’s Daily reported, all the Chinese astronauts are excellent pilots with hundreds or even thousands of hours of flight time. They also receive hundreds of classes to prepare for space travel.
One of the toughest(艰苦的) parts is the high-G training. It simulates(模拟) the environment when the spacecraft takes off. Sitting in a super-fast spinning(旋转) machine, astronauts’ face muscles(肌肉) change shape. They cry tears as they spin. Blood can’t flow to their brains properly, causing a lack of oxygen(缺少氧气) and even blindness. Astronauts must operate(操作) the spacecraft under these conditions.
Another exhausting exercise, as Wang Yaping told People’s Daily, the underwater training which lasts seven hours each time. It simulates a weightless environment. She had to wear a 200-kilogram suit and do tasks in 10-meter-deep water without eating or going to toilet. After each training, Wang lost up to 2kg body weight.
“We may have to repeat such training every single day for years or decades,” said Wang. “But there is no “give up” in our dictionary.”
