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 . When water is cold, people will find it uncomfortable to swim. Wetsuits(潜水服）can help keep people warm.
The wetsuit doesn't have a long history. According to studies, the wetsuit only began during WWII when Italians started wearing wetsuits that were made of rubber. And it was widely believed in 1951, Hugh Bradner began working to improve the equipment.
Now there are many kinds of wetsuits. Contrary to what some may think, wetsuits do not work by keeping the diver(潜水员）dry; they are designed to let water into the suit. This thin layer of water is trapped（保存）between the diver and the suit. And it's allowed to move between the skin of the diver and the inside layer.
Wetsuits can also differ in thickness. They range from about 0. 5mm to 8mm in thickness. It's true that thicker wetsuits are more likely to affect your movement.
| A．But they're much better at giving you warmth. |
| B．As for the difference, wetsuits can differ in size. |

5 . As more people move into their golden years, many families are welcoming their senior parents into their homes. While most seniors claim to prefer to age in their own homes, safety and health concerns don’t always make this possible.
If you are preparing to welcome a senior parent into your home, everyone will have an adjustment period. This type of move will have physical, emotional, and mental influences for the whole family. Here’re a few tips to help you open your heart and home to your senior parents.
You may be excited about having your senior parent move in, but that doesn’t mean they will share your enthusiasm. Being asked to move out of their own home can be very upsetting for your parents. So it’s important to be patient with them and allow them the time to adjust to their new environment.
It’s also important to give your parents a space of their own. Before you decide to bring a senior parent into your home, you need to consider if you have enough space for them.
Then, for adult children, offering a senior parent a safe home is a priority. Before moving, you will need to make some changes around your home to help your parents stay safe. For example, install grab bars in the bathroom, repair all stairways, add anti-slip mats to the kitchen and so on. And arm yourself with knowledge like First Aid courses.
In addition, your senior parent will be used to being in charge of their own home and is likely to feel like a bother as they begin to settle in your home. One effective way is to assign them a household responsibility. Ask your parents to look after the dog or cook a meal to make them feel like an active and important part of the family.

6 . Europe is the perfect place for a holiday. Every corner of the continent is bursting with history, culture and sights. The countries are so very close to one another, and yet so completely different.
Sweden
Sweden is a brilliant destination for a campervan (露营车) holiday, with hundreds of well-appointed camping sites suitable for vehicles. Head north to Lapland in the Arctic Circle and you’ll find true wildernesses where you can truly get close to nature. Head here between June and mid-July and you’ll be able to take in the midnight sunshine. If you’re looking for great nightlife, head to Gothenburg, Stockholm or Malmo.
Germany
There are massive industrial cities, rolling plains, towering mountains, deep forests and long, sparkling rivers. It’s not just what’s to see that makes Germany so great, but the ease of seeing everything. All these wonderful locations are all linked by one of the world’s best road systems.
Scotland
Scotland has something for everyone: cities with rich nightlife, incredible scenery, wonderful lochs and medieval (中世纪的) castles. If you want to get away from it all, then the Highlands are one of the least populated areas in the whole of Europe. Hikers will love the Cairngorms – the largest national park in the UK.

7 . Scientists have discovered how plants manage to live alongside each other in places that are dark and shady. Plants in the deep darkness of a thick forest, where natural supplies are not very great in amount, won’t attempt to top their neighbors in growth as those in moderate (中度的) shade do. In deep shade conditions, it would be a waste of energy and harmful to survival because green shoots would never be able to top their larger neighbors in growth.
So how do plants prevent such growth in deep shade conditions? The secret lies in the clocks insides them, say scientists from the John Ines Centre and the University of Bristol.
They have discovered that when plants notice deep shade, this changes the expression of genes parts of the circadian clock (昼夜节律时钟) — the inner daily timer found in plants and other things. These clock parts perform an additional role in preventing plants from lengthening and overtopping neighbors.
The work identifies a previously unknown role of the circadian clock in controlling plant development and the findings may have possible effects on both natural plant populations and crops. Professor Antony Dodd of the John Innes Centre said, “The biological clock of plants plays a big part in their development and fitness. This work casts new light on a new role of the circadian clock in adapting plants to competition with other plants in their environments.” “It also gives us new insights into how plants adapt to very deep shade, where resources are very limited,” said Professor Kerry Franklin at the University of Bristol.
This work provides evidence for the firmness of the circadian clock in stressful environments, and information that may be useful in developing new generations of crops in a challenging climate.

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.”
