Billionaire Bill Gates has offered the many thousands of graduates some career and life advice. Over a series of 14 tweets in his Tweeter posted last Monday, the world's richest man used the words “impact”, “happiness” and “progress”. He did not mention money. Instead, he told the graduates what jobs he would be looking for if he started out today.

“AI (artificial intelligence), energy and bio-sciences are promising fields where you can make a huge influence”, he wrote. Earlier this year, Gates—who famously dropped out of Harvard to found Microsoft—said that artificial intelligence had “ phenomenal” potential, and “anything connected with that would be an exciting lifetime career.” In the same speech at Columbia University, he said there is a huge growing demand in the energy field to develop reliable, cheap and clean energy.

    As well as urging new graduates to surround themselves with people who challenge you, teach you, and push you to be your best self, Gates reminded them to think of others, especially the less fortunate.

    He wrote that it had taken him decades to learn about the world's worst unfairness and described this lack of early understanding as his one big regret. “You know more than I did when I was your age,” he wrote, “ You can start fighting unfairness, whether down the street or around the world sooner.”

    He finished by asking graduates to consider the progress human has already made, saying that he believe the world is getting better. “ That matters because if you think the world is getting better, you want to spread the progress to more people and places.”

    Insects(昆虫) are a very healthy food. They have almost as much protein(蛋白质) as meat from a pig or cow and are low in fat. Eating insects is also very good for the environment since they need less land and water than larger animals.

    Marcel Dicke, who studies insects, explained in a talk how insects also produce more meat from the food they eat. For example, imagine a farmer feeds a cow 10 pounds of food. Those 10 pounds of food produce about 1 pound of meat for people to eat. However, imagine the farmer gives a certain number of insects 10 pounds of food. Those 10 pounds of food produce 9 pounds of meat for people to eat!

    Eating more insects can also help people in poor areas. Many people can raise and sell insects, which can provide jobs and food.

    But insects will not replace animal meat very quickly. First, people in some countries would have to change how they think about eating insects. Many people in North America and Europe eat a lot of meat like beef and pork. But they do not traditionally eat insects. In fact, for many people in the west, eating insects sounds crazy. They believe insects are dirty and dangerous. Insects make them feel uncomfortable.

    Some people are trying to deal with this problem. For example, David George Gordon wrote a book named “The Eat-A-Bug Cookbook”, which tries to show people that insects can be delicious. Other insect experts travel around telling people about the benefits of eating insects. But they will still have a lot work to do.

    When Rebecca Saxon was diagnosed with cancer at the young age of 27, she thought her life was over. But in her darkest hour, inspiration struck and she found a way of turning her misfortune into advantage.

    Following her cancer treatment, Rebecca launched a successful business "Something Blue Bridal Shoes"—a unique range of wedding footwear, which came out of the fashion pictures she drew while recovering in her hospital bed.

    Rebecca, from London, says, "I started designing wedding shoes with blue soles (鞋底) when I was halfway through my cancer treatment. I had a hit when I was diagnosed with cancer but I decided that I was going to pick myself up and fight this cancer. The pictures were my release and the way I got through the many hours spent in a hospital room. I had no idea what was going to happen to me, but I knew I had to be positive if I was going to overcome this treatment. I told myself this was not going to be the end for me. I decided to fight with my negative feelings and start drawing."

    Rebecca had always loved fashion since she was younger. Several of her friends were getting married at the time when she was ill. "So at first, I would be drawing designs for wedding dresses and other clothes. But then I started drawing wedding footwear—designing shoes with blue soles which were very comfortable too. I thought it would be a lovely way of combining the 'something old, something new, something borrowed, something blue' tradition. Drawing really helped me deal with my treatment," said the brave girl.

    With the encouragement of her boyfriend, she turned her dreams into her reality and set up "Something Blue Bridal Shoes". Each beautiful shoe has a blue sole, combining the age-old tradition of what a bride should wear at her wedding for good luck.

I often teach about happiness and what has become clear is this: There are some qualities unhappy people always have. Here are some of them.

 Happy people know life can be hard and tend to live through hard times. They take responsibility for how they got themselves into a mess, and focus on getting themselves out of it as soon as possible. Unhappy people see themselves as victims of life and stay stuck in the "look what happened to me" attitude instead of finding a way through and out to the other side.

    Most happy people believe in the good in people instead of thinking everyone is out to get them. Generally open and friendly towards people they meet, happy people foster(培养) a sense of community around themselves and meet new people with an open heart. Unhappy people are distrustful of most people they meet and don't think strangers can be trusted. Unfortunately, this behaviour slowly closes all chances of meeting new friends.

    Unhappy people believe someone else's good fortune is stolen from their own. They believe there's not enough goodness to go around and always compare others' against theirs. This leads to jealousy(嫉妒). Happy people know that others' good luck and superior circumstances are just signs of what they also can achieve if they try hard enough. They believe in unlimited possibilities and don't get stuck in thinking one person's good fortune limits their possible outcomes in life.

    There's only so much space between the two ears. Unhappy people fill that space with constant worry and fear. Happy people experience fear and worry too, but they make an important difference between feeling it and living with it. When fear or worry crosses happy people's minds, they'll ask themselves if there's an action they can take to prevent their fear or worry from happening and they take it. If not, they realise they're spinning in fear and they lay it down.

The best way to deal with sports injuries is to keep them from happening in the first place. Knowing the rules of the game you are playing and using the right{#blank#}1{#/blank#} （equip） can go a long way toward preventing injuries. If you think you have been injured, pull{#blank#}2{#/blank#} （you） out of the game or stop{#blank#}3{#/blank#} （do） your activity or workout. Let a coach or parent know what happened in case you need to see a doctor. Serious head and neck injuries happen most often to athletes{#blank#}4{#/blank#} play contact sports like football. Keep the injured person still with his or her head{#blank#}5{#/blank#} （hold） straight while someone calls for emergency{#blank#}6{#/blank#} （medicine） help. If the person{#blank#}7{#/blank#} （lie） on the ground, do not try to move him or her. 

Your first question after a sports injury will{#blank#}8{#/blank#} （probable） be, "When can I play again？"This depends on the injury and what your doctor tells you. Even if you can't return to your sport right away{#blank#}9{#/blank#} what you can do to stay fit. Always check with your doctor{#blank#}10{#/blank#} trying any activity following an injury. 

The ancient Egyptians were known for their carefully record-keeping, documenting prayers, declarations, and taxes. This extensive writing has now been linked to physical marks on the bones of the kingdom's scribes, as revealed in a new study published in Scientific Reports.

The study focused on the bones of 69 adult men buried between 2,700 and 2,180 B.C. at Abusir. The researchers identified 30 of these individuals as either professional scribes or high-status officials who needed language skills for their work. These scribes exhibited specific physical characteristics related to their occupation. Many had osteoarthritis in their right collar bone, shoulder, and thumb, likely due to the repetitive movements involved in writing. Their ankle and leg bones were flat from sitting cross-legged for extended periods, and they also showed signs of spinal(脊柱) osteoarthritis, possibly from looking up to listen and then bending over to write on papers.

An fascinating finding was the prevalence of jaw joint issues among the scribes, which 

the researchers speculate might be associated with chewing on reed(芦苇) pens. The ink for these pens was typically black from soot(烟灰) or red from iron for important documents.

However, not all scholars are convinced by the study's conclusions. Cynthia Wilczak and Danny Wescott, who were not involved in the research, argue that more evidence is necessary. Only six of the 30 bones were confirmed to be scribes based on their titles, while the rest were identified based on their tomb locations and social status. Additionally, there is no dental evidence to support the theory that the scribes chewed on pens.

Despite these criticisms, Brukner Havelková and her team aim to expand their research by examining scribe remains from other locations to confirm their findings. While this study is just the beginning, it offers a unique perspective into the lives of ancient Egyptian scribes and the physical cost their work demanded.
