1 . In looking through your social media, there’s a good chance you’ve noticed pictures accompanied by texts. The pictures are likely made possible by a text-to-image program called DALL-E. For example, Twitter user posted a tweet with the text, “To be or not to be, rabbi holding avocado, marble sculpture.” Then a matching picture appears below.

The AI models come from Google’s Imagen software as well as OpenAI. a start-up backed by Microsoft. On its website, OpenAI calls DALL-E “a new Al system that can create realistic images and art from a description in natural language.” But most of what’s happening in this area is coming from a relatively small group of people sharing their pictures. That’s because Google and OpenAI have not made the technology broadly available to the public.

The text-to-picture services identify the most important parts of a user’s text and then guess the best way to picture those terms. There’s generally a text box, a button to start the generation process and an area below to display images. To indicate the source. Google and OpenAI add watermarks in the bottom right comer of images from DALL-E and Imagen.

Engineers trained the models on various collections of words and pictures from the web. OpenAI recognizes the potential for harm that could come from a model. To avoid the risk, employees removed violent content from training data, and there are filters（筛选）stopping DALL-E from producing images if users submit（提交）violent or illegal content.

Boris Dayma, a developer from Texas spelled out the problems in an explanation of their software. Despite the risks, Dhariwal, a research scientist at OpenAI, said it could open up creative opportunities for individuals and could help with commercial applications for dressing up websites. Results should continue to improve over time.

2 . Picture the scene: you’ve spent years working towards a very specific goal. You’ve put in countless hours of work and made many efforts along the way, but now that you’ve got there it doesn’t feel quite like you imagined. Instead of celebration, you feel emptiness, confusion and doubt.

Welcome to the anti-climax. The often-experienced but seldom-discussed downside of achieving life’s biggest milestones. Many of us work tirelessly towards our goals. We may spend our lives dreaming of the day we get married, publish our first hook or buy our first home. However, oftentimes, when we achieve these things it doesn’t feel quite as expected. In fact, the achievement of these goals feels a bit of a letdown.

So why do we often experience an anti-climax with big goals, even though we’re happy to achieve them? “An anti-climax can be an unexpected by-product of a milestone achievement. Usually, the more significant the milestone, the greater the anti-climax may be. The intensity（强度）of an anti-climax often relies on what we expect of this achievement.” says Rachel Vora. a psychotherapist（心理治疗师）.“The journey to achieving a milestone can he exciting and tiring in addition to giving us a sense of purpose and focus. Therefore, when this disappears overnight. we can often feel lost and confused, in spite of feeling proud of our achievement.

When this happens it can contribute to a mixture of emotions. We often falsely believe that we’ll feel completely different afterwards or that our feelings of low self-worth will disappear, but this is rarely the case. “Clients（客户）often present to me with an extremely great sense of ‘is this it?’ and ‘what now?’.” says Vora. “These feelings of confusion and disappointment, if let ignored, have the potential to cause clients to be in low spirits, or even worse.”

3 . Most young people are always on their phones, which may upset many people. ___________, a group called Girl Scouts are receiving _________ for setting up their first walk-in clinic for elderly people, who have difficulty understanding how to ___________ the secrets of their smart phones.

Each teen spent at least an hour of one-on-one time with their oldsters. Based on their _________ knowledge, each Girl Scout was assigned to ___________ different aspects of Android and Apple phones.

Some of the oldsters actually wanted to take part in e-commerce (电子商务), and needed help to _________ a payment account on their smart phones while others simply had _________ when learning how to send messages to their family members. "I was teaching this older woman how to _________, and the first thing she did was to send a message to her daughter,” one of the Scouts said. “How ___________ it was! It just made me feel really, really happy.”

In addition to arranging group lessons for all of the seniors to ____________ together at the end of the clinic, the youngsters even printed out brochures and guides for the seniors to take home in case ____________ seniors would encounter problems with their smart phones in the future.

The eighth graders earned their “Silver Award,, for their job. After experiencing the ____________ of their project, the girls hope to organize more ____________ in the near future. “Those girls were just great,” said Nancy, a great-grandmother who once ____________ the clinic. “They were ready for us and had a very mature attitude about answering our questions, and they ______________ the praise.

5 . I began a new job in a new city six months ago. Big moments of changing like this have a way of dragging up deep, hidden fears we don’t face in our longer periods of stability.     1     .I was constantly losing sleep, had lots of panicky doubt, and even some regret when I thought about the job I just left.

Change is risk. Our primitive brains translate risk into danger, and our survival as a species depends on avoiding it. Though philosopher Nietzsche famously said, “That which does not kill us, makes us stronger”, the risk that it could kill you can easily cause anxiety.     2     . Me, no exception.

Unluckily, there are always big changes we must face at some point.     3     . The first thing I did when I doubted myself and my decision to take a new job and move to a new city was talk to people who know and care about me. So blinded was I by change-caused anxiety that I had lost sight of my common sense. I reached out to my friends and my old boss. They gave me so much good advice that I wrote it down and referred to it often in those early weeks.

    4     . Simply thinking about the past challenges where you came out on top is a reminder that you will do so this time as well. Sometimes our greatest difficulties become our greatest moments of success.

Change, while requiring adjustment—sometimes painful adjustment—often finds its way back to balance. Change and struggle are usually the only ways to get to someplace better.     5     . So, the sooner you discover what helps you adjust, restart, and succeed during change, the easier it will be to bag the next peak.

9 . Lapland's reindeer (驯鹿) grow well in winters of -30℃ and even colder. So when rain falls instead of snow during the coldest months in the Arctic,it makes food hard to get for them. Now one of the best-loved symbols of Christmas is probably dying out. Numbers have fallen by over half in the last two decades as the place warms at four times the global average rate.

The animals are used to pull sleigh (雪橇) rides for tourists. The rides are part of Lapland winter wonderland experiences in thousands of British tourists each year. But this year the working herd had to be moved 60 miles further north due to the absence of snow. As a result, they can't be provided in some areas, making it hard for people to earn a living.

Lapland is often described as Europe's last great wilderness, home to lynxes, brown bears, wolverines and golden eagles. Tourism is a big part of the economy, and the town of Rovaniemi is also the "official home of Santa Claus". But changing climate (气候) is threatening its tourism industry. A report by The Finnish Climate Change Panel warns of flooding and increased rainfall, with Rovaniemi most at risk. Firms that rely on snow "will have great effects on visit levels" and these industries may be forced further north.

Erkkila of the Arctic Husky Park in Rovaniemi says: "Tourists see pictures of the Santa Claus village covered in snow and when they get here they think, 'Is this the winter wonderland?'." The Husky Park bought a wheeled cart (车) six years ago as a replacement for sleigh rides when the snow fails.

In the past it was thought the Arctic was warming twice as fast as the rest of the world. But a report published last week by scientists showed the rate is actually four times the global average.

10 . Recent research discovered that a low-cost computer training program can help older persons drive less dangerously.

“We developed a training program, called Drive Aware, which could be used by anyone who has a computer,” says Jing Feng, co-author of the study and a professor of psychology at NC State. “Drive Aware is a cognitive (认知的) training program for older persons that helps them notice traffic risks more effectively. The purpose of our recent study was to see how much Drive Aware changes trainees’ driving behaviors once they get behind the wheel.”

The researchers found 27 persons aged 65 and up to test Drive Aware. In a driving simulator (模拟器), all of the study participants (参与者) experienced a basic driving exam. The “active training” group was made up of nine of the study participants. Every two weeks, the active training group had two Drive Aware trainings. A group of nine additional study participants was asked to take “passive training”. This group watched videos of others receiving the Drive Aware instruction. This happened twice, with each lasting about a week. The control group, which was made up of the remaining nine study participants, received no training. After that, all 27 study participants performed a second driving exam in the simulator.

The study participants in the active training group experienced 25% fewer “unsafe incidents (事件)” following the training, according to the researchers. There was no obvious change in the number of dangerous incidents among study participants in the passive training and control groups.

“This testing was done with a fairly limited number of study participants,” Feng says. “If we can succeed in getting the fund, we’d like to further our testing with more people to clearly prove how effective this training is at reducing accidents among older drivers.”
