China is determined to land its astronauts on the moon and set up a scientific station there,according to a project leader.
Zhou Yanfei,deputy chief designer of China's manned space program,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,explore ways to develop lunar resources and strengthen the nation's space capabilities.
"A new wave of lunar explorations has been emerging in the world,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,"he said in a report delivered at the 2020 China Space Conference in Fuzhou,Fujian province."Unlike other nations,China must depend on its own science and technology to realize our goals."
The country is independently able to land its astronauts on the moon because it has the technologies,a group of well-trained,innovative professionals and high-efficiency research and management systems,Zhou said."However,our existing carrier rockets can't perform landing missions to the moon because they are not powerful enough.The Shenzhou- series manned spaceships are not suitable for lunar expeditions.We don't have a lunar landing capsule,"he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface.
To solve the problem, we set out to produce a powerful launch vehicle. Zhou said researchers thought about two approaches-making a new heavy-lift rocket,or adjusting the next-generation rocket designed to carry astronauts,which is under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.
The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 meters tall,with a diameter of 5 meters,which would make it almost twice as tall as the Long March 5,currently the biggest of China's rockets.

【推荐1】The death of the plastic credit card could be a step closer as high street names including McDonald's and the Co-op prepare to test a breakthrough finger-scanning payment technology.
FingoPay, developed by British start-up Sthaler, uses a biometric reader to scan the veins of a shopper’s finger, building up a “map” that is unique to each individual.
By connecting this pattern with a credit card or bank account, the company plans to let shoppers pay simply by placing their finger in a pocket-sized scanner, doing away with cash and credit cards.
Sthaler, founded by former music industry executive Nick Dryden, will begin testing the technology next month in Proud, a London nightclub. Mr. Dryden said McDonald's is experimenting with a pilot of the technology, and that Sthaler is also planning a project with Co-op’s food stores.
It comes amid growing interest in using biometric identification in payments, which backers believe are more secure and efficient than passwords and PINs. Apple Pay, which uses the iPhone’s fingerprint technology, launched in the UK in 2015 and was followed by the Android equivalent in May 2016.
Hendrik Kleinsmiede, the director of Visa Europe’s innovation arm Collab, which is backing Sthaler, said the Fingopay technology was less immune to problems such as wet and dusty fingers or fraud. “People are ready to accept biometrics as a secure authentication mechanism,” he said.
Sthaler says the chance that two people have the same vein structure is 3.4bn-to-one, making it virtually impossible to crack. The vein scanner, developed by Hitachi, is already being used by Barclays to identify business customers as well as in cash machines in Japan, but Sthaler has the unique rights to license it to retailers.
In the trial at Proud set to begin in September, the technology will be used to speed up waiting times at the bar both by cutting down on cards and by being able to suggest drinks based on what a patron has previously ordered.

【推荐3】From writing Shakespeare-style poetry to making music, ChatGPT has amazed he world since its launch in late 2022 by the US-based company OpenAI. It even passed several law exams in four courses at the Unlversity of Minnesota, US.
The AI program can answer questions on a whole host of topics and write essays, stories and any other written texts you can think of. It does this by drawing on information collected from a large corpus (语料库) of text data.
What makes ChatGPT so impressive? As Sam Altman, the CEO of OpenAI said n an interview, “It’s not actually a fundamentally new technology that made this (ChatGPT) have a moment.” According to MIT Technology Review, ChatGPT is based on GPT-3, a large language model. Because texts are more complex than the meaning of every word combined, language models require a type of neural network (神经网络) that can make sense of texts.
One breakthrough behind today’s model is a network called Transformer, which was invented by Google researchers in 2017. The neural network can infer word meanings by tracking where the word appears in a sentence. Transformer can therefore gather the meaning of texts more accurately.
The GPT models were built by OpenAI combined Transformer with unsupervised (无人指导的) learning, meaning that the models can learn by themselves without being told what to look at. ChatGPT can now generate human-like responses instantly due to the large scale (规模) of texts It made sense of and learned from.
“One of the biggest problems with ChatGPT is that it comes back, very confidently, with falsities,” Michael Wooldridge at the Alan Turing Institute in London, UK. This means that ChatGPT doesn’t know the truth about the world — it learns information from various resources but It cannot decide what is true or false. As for education, many US schools recently banned students from using ChatGPT on school networks because students began to use it as a shortcut for essays.

【推荐1】Junk food is everywhere. We’re eating way too much of it. Most of us know what we’re doing and yet we do it anyway.
So here’s a suggestion offered by two researchers at the Rand Corporation: Why not take a lesson from alcohol control policies and apply them to where food is sold and how it’s displayed?
“Many policy measures to control obesity (肥胖症) assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods,” note the two researchers.
“In contrast,” the researchers continue, “many regulations that don’t assume people make rational choices have been successfully applied to control alcohol, a substance - like food - of which immoderate (过度的) consumption leads to serious health problems.”
The research references studies of people’s behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:
Density restrictions: licenses to sell alcohol aren’t handed out unplanned to all comers but are allotted (分配) based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.
Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren’t primarily food stores?
Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can’t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they’re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.
1. What does the author say about junk food?A.People should be educated not to eat too much. |

【推荐2】The second little pig was unlucky. He built his house from sticks, which was blown away by a wolf. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by an agent for the construction industry, strongly favoring brick, concrete and steel. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.
No other building material has environmental credentials (认证信息) as exciting and overlooked as wood. The energy required to produce a laminated wooden beam (层压木梁) is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing, wooden buildings contribute to negative emissions by storing the stuff. And for refitting older buildings to be more energy efficient, wood is a good insulator (绝缘体). A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium (铝) equivalent.
But such bigger stories are still uncommon. Governments can help push the industry to use more wood, particularly in the public sector — the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are presented in materials.
Construction codes could be regulated to make building with wood easier. Here the direction of travel is wrong. Britain, for instance, is banning the use of timber on the outside of tall buildings after 72 people died in a tower fire in London in 2017. That is a nonsense. Grenfell Tower was covered in aluminium and plastic, not wood. Modern cross-laminated timber (交叉层叠木板) panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than is appreciated. The second little pig was not wrong, just before his time.

【推荐3】How can we possibly cope with the large amount of information about virus spread, canceled plans and uncertainty about the future? Some people are buried in the fear, anxiety and sadness, checking news sites and social media constantly. Others try to be prevented from knowing it all and ignore the outside world.
There's a third option, though. Rather than fully getting involved in the negative or ignoring it, we can do our best to experience joy alongside everything else that is sad in the world. In fact, research that and others have conducted suggests that allowing the two different emotions to coexist may actually benefit us in the long run.
Dr. Jeff Larsen and his colleagues invented an expression known as the “coactivation model of mixed emotions”, and the basic idea is that we may be able to deal with, and learn from negative emotions like sadness if we experience them concurrently with positive emotions like joy at the same time. Here, positive emotions provide a psychological buffer (缓冲),making it easier for people to deal with the things they don't want to face.
The comedian Mitch Hedberg proposed ananalogythat captures this essence quite well, noting that it would be cool if you could eat a carrot with an onion ring and they would travel down to your stomach. Then they would get there, and the carrot would say, “It's cool, he's with me.” Applied to our emotional lives, we could do a better job in digesting,processing gaining insight into the negative events in our lives if we could do so alongside the positive.
Several years ago, my partner Jon Adler and I set out to test this exact idea. Specifically, we looked at sample of adult volunteers who signed up for weekly mental , health therapy sessions. Between each week, they reported the feelings they were having and also took a few questionnaires that were meant to assess their overall health. This design allowed us to examine how different emotional experiences would impact mental health in a longitudinal fashion, over the course of 12 weeks.
It's worth noting first that everyone seemed to improve a bit as the weeks marched on:therapy helps and so does time. More to the point, though, mixed emotions at one time point were positively associated with improvements in psychological well-being at the next time point. The more of a mixture of, say, happiness and sadness someone experienced today, the better feeling they'd experience next week.
However, when we looked at mixed emotions that were experienced in a given week, they weren't associated with improved mental health in that same week.
The true benefit from mixed emotions may not happen immediately, but rather, likely happen sometime in the future.

【推荐1】Scientists have not found any signs of life on Mars yet,but they say a robotic vehicle called “Curiosity” is helping them learn a lot about the planet’s history and climate.
Curiosity landed on Mars in August 2012 after travelling through space for more than eight months.It was sent to Mars by scientists from NASA in the United States.
Curiosity is about the size of a car and has six wheels.It also has a robotic arm,cameras,and instruments that allow it to examine things it finds on the surface.Then it sends the information back to the earth.
Curiosity’s main task is to find out if anything could live on Mars,either now or in the past.On Nov.2,NASA scientists held a press conference (新闻发布会) to discuss what Curiosity had found in its first two months on Mars.
Curiosity has found soil that is similar to the sand formed by volcanoes (火山) on the earth.Scientists say that studying the minerals in Martian soil will help them understand what conditions were like on the planet in the past.Curiosity also found smooth stones like the ones found on river beds and seashores on the earth,where their rough edges have been worn down by water.Mars is very cold and dry now,but scientists say the smooth stones tell them that a river used to run through the place where they were found.
Curiosity has been testing the atmosphere around Mars for a type of gas called methane (甲烷),but so far it has not found any.On the earth,most methane is produced by plants or animals.Methane on Mars might indicate that some type of tiny plants or animals lived there.
Curiosity is the fourth robotic vehicle to be sent to Mars.It will continue to explore the planet for about two years.

When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.
The image you create for yourself has rather strange proportions(部分); certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.
Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent right and left and a top and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.
If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes (中风)which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.

【推荐3】For as long as we’ve known about it, humans have searched for a cure for cancer. Across the world, countless amounts of time and money have been spend on researching a way to stop the terrible disease.
But now, it seems like the answer could have been inside our own bodies the whole time.
Recently, the Food and Drug Administration (FDA) in the US, a government agency that’s responsible for healthcare, approved a new form of gene therapy that could mean the end of a certain type of cancer.
The therapy allows scientists to “train” the immune cells of sick patients to fight leukemia – a blood cancer that mostly affects young people.
The exciting new treatment works by removing healthy immune cells from the patient, known as T-cells, which are then altered to be able to “hunt down” cancer cells.
The cells are then put back into the patient, before they begin to get rid of the patient’s leukemia over time, similar to how the body fights off other illnesses.
“This is truly an exciting new day for cancer patients,” Louis J. DeGennaro, president of the Leukemia and Lymphoma Society, said in a news release. Up until now, a drawn-out (持续很久时间的)and painful bone marrow transplant was the only option for many leukemia patients.
In this procedure, healthy blood cells are taken from a donor and placed into the sick patient, who also has to go through chemotherapy to allow their body to adjust to the new cells.
But with a recovery rate of around 83 percent–according to a news release published by the FDA–it’s hoped that the days of painful trips to the hospital, or even death, are over for leukemia sufferers.
“We’re entering a new frontier in medical innovation with the ability to reprogram a patient’s own cells to attack a deadly cancer,” FDA commissioner Scott Gottlieb said in the release.
“New technologies such as gene and cell therapies hold the potential to transform medicine and... our ability to treat and even cure many intractable(难治的) illnesses.”

Although the size changed, the model is actually thinner and lighter than last one. It comes with a high-resolution “retina” screen that’s sharper than the 4S, according to Apple.
So far, demand for the iPhone5 has been higher than expected (预计的), with 2 million pre-orders (预定) made in the first 24 hours. But while the new phone excited many people, it also left a lot of people disappointed (失望). Mat Honan called the iPhone5 “completely amazing and very boring”. “Though we’ve reached the sixth iPhone, things have got so good that Apple does not change very much any more,” he said. “And so you get the iPhone5, which looks like a longer, thinner one of the iPhone4.”
When Steve Jobs introduced the iPhone back in 2006, it won praise from all over the world. Similar praise was given to Apple when it introduced the first iPad in 2010.
However, recent smart-phone designs have failed to satisfy people as much. Stephen Shankland said “it’s time to lower your expectations (期望).” This is because we have entered a time where it is harder for phone designers to come up with better ideas and changes. It could be some time before someone comes up with the next big idea.

【推荐2】SHOULD WE FIGHT NEW TECHNOLOGY?
This morning, I saw the shocking headline: “Passenger Dies When Car Crashes in Driverless Mode”. In the article, a lot of people said that the public should oppose the idea of developing driverless cars. They said that some advances in technology were unnecessary and could even be dangerous. Hence, we should cease accepting technology just because it is new. The newspaper reported that the car company had already apologized for the accident, but the families of the deceased said it was not enough. Nevertheless, the company still claimed that most people would be travelling in driverless cars one day soon.
On the one hand, there are many different groups of people around the world who live happily in the absence of new technology. Probably the most well-known are the Amish, a group of Christians living in rural America. They do not own or drive cars, watch TV, or use the Internet. They have lived mainly as farmers since the 18th century, and they will probably be living the same way in the distant future. They advocate a simple life with an emphasis on hard work, family, and community. They think that is better than caring about luxuries or following the lives of the rich and famous. It could even be argued that the Amish’s quality of life is better since they live in and appreciate the natural environment rather than living in large, polluted cities.
On the other hand, new technology has provided people everywhere with many benefits over the years. For example, the latest weather-tracking computer programs give people lots of warnings about potential natural disasters, which saves many lives. Moreover, the Internet has made it possible for friends and family to keep in touch easily even if they are on opposite sides of the world. It has also made finding opportunities in life much easier, as it allows people to make larger networks of friends through using social media.
Personally, I have benefited quite a lot from technological advances. I found my career as an AI designer through a social media network. My health monitor, which I wear all the time, has also helped me get into the best shape of my life. Of course, when new technology changes the way we live, it can be a scary prospect. Nevertheless, I will always look on the positive side of change and accept it rather than resist it.

【推荐3】Do you jump out of bed early, wide awake and ready to start your day?If so, you would be called an “early bird”. Perhaps, you hate the sound of your alarm clock each morning and have little energy until afternoon. If so, you're probably a “night owl”.
Most people can be divided into such two groups, but what makes us this way?And is one better than the other?There are different opinions.
Usually, early risers have been praised as hard-working while those who prefer to get up late are considered lazy. Most people believe the early bird catches the worm.
Yet some scientists now believe “night owls” can really focus(集中) longer and produce more than early risers.
Research has found that the early bird does not always get the worm. In a Belgian study, both “morning people” and “evening people” were watched during their normal asleep and awake routines(常规).After 10 hours of being awake, the “evening people” became more alert(思维敏捷的). However, the “morning people” became sleepy and less focused. Researchers believe the reason for this difference is that night owls receive a last-minute increase from their brains. This added energy allows them to stay alert for longer periods of time.
Environment, lifestyle, activities and childhood routines all may have an effect on sleeping habits, yet genetics(遗传学)may play the biggest role.
It is possible to change your sleeping habits through regular bedtimes, early exercise and by avoiding midnight snacks. But if you're happy rising early or staying up late, you're probably doing what works best for your own personal body clock.
