Here's how yo-yo dieting affects your body and your mind

    Yo-yo dieting, also known as weight cycling, occurs when a person experiences periods of weight loss followed by weight gain followed by weight loss and so on and so on. The effects of this weight cycling are significant, even when the weight lost and gained is as little as 10 pounds.{#blank#}1{#/blank#}

    It can make you gain weight

    While dieting may help you lose a few pounds at first, it only works temporarily. Your body responds to the lack of calories by turning to lean muscle mass for energy. Once you have returned to your normal eating habits, the weight comes back on –{#blank#}2{#/blank#}

    {#blank#}3{#/blank#}

    Yo-yo dieting may increase the risk for heart disease and sudden death in post-menopausal（绝经后期）women. Studies found that when normal-weight women experienced periods of weight cycling, they were 3.5 times more likely to have sudden death than women whose weight remained stable. In the same study, yo-yo dieting increased a woman's risk of death by 66 percent.

It can be damaging to your skin

    Dermatologist (a doctor who studies and treats skin diseases) Robin Evans weighed in on the effect that yo-yo dieting has on the skin. “The up and down weight losses and gains can have harmful effects on the skin especially on the face with stretching and contracting the skin,” said Evans{#blank#}4{#/blank#}.

It plays games with your mind

    Yo-yo dieting is hard on the body,{#blank#}5{#/blank#} Repeatedly gaining and losing weight can leave dieters feeling more depressed about their weight and losing self-belief as a result.

    If you're a yo-yo-dieter, talk to your health care provider about lifestyle changes that can help you maintain a stable and healthy weight for years to come.

A. It only works temporarily

B. It can damage your heart

C. but in the form of fat, not muscle

D. but it's even harder on the mind

E. but with a smaller size, you will make yourself less friendly

F. The result ends up more wrinkles and an overall effect of aging the skin

G. We turned to the experts to find out how yo-yo dieting can affect your body and your mind

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize (强调) the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries -- like the UK or France -- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    The colors that you select create a distinct atmosphere in the room. {#blank#}1{#/blank#}

    Pick the color for your room and you can create whatever you feel like. The color will also help you to enlarge the space or making it more inviting, which will also make differently all about it.

    However, the trick is to select the right version of that particular color. There are different hues (色调) for blues, for instance. {#blank#}2{#/blank#} Here we have presented a guide that will let you gain a deep insight about the colors.

    Blue

    {#blank#}3{#/blank#} For kitchen, bathrooms and bedrooms it is an ideal choice. Of course it is also associated with sadness that means it may not strike note for each and everyone. It is a popular choice among people. Blue comes from the cold side of the color wheel, so it can make the room feel cold, unless and until it is south filling space. If you are attracted to blue color, think of going for purple, or mix red and purple.

    Dark blues are best for a living room. Probably it is best reserved for high ceiling space. {#blank#}4{#/blank#}

    Green

    Like blue, green is also a calm shade. {#blank#}5{#/blank#} It is the shade that reflects nature and renewal. Green produces a positive energy without the feeling of overstimulation.

A. Colors can light up the mood of the room.

B. You can use it for a living room or a bedroom.

C. It will make you feel the wall appear near to you.

D. Traditionally, blue is related to calmness and comfort.

E. It is better that you select colors that are warm like blue.

F. They won't create similar effect and atmosphere generally.

G. But before driving into any decision here's what you need to know.

    When Boris left school, he could not find a job. He tried hard and he wrote letters to many companies until he could not afford to buy any more stamps. Boris began to lose his confidence, then depressed. Still he went on trying and still he failed. He began to think that he had no future at all.

    "Why don't you start your own business?" one of his uncles told him. "The world is a money­locker. You'd better find a way of opening it."

    "But what can I do?"

    "Get out and have a look round." advised his uncle. "See what people want; then give it to them, and they will pay for it."

    Boris began to cycle around the town and found a suitable piece of waste ground in the end. Then he set up his business as a cycle repairer. He worked hard, made friends with his customers and gradually managed to win his good fame. A few months later, he found that he had more work than he could deal with by himself. He found a number of empty shops but they were all no good: in the wrong position, too expensive or with some other problems. But at long last, he managed to find an empty shop in a new place where there were plenty of customers but no competition.

    Boris and his assistant taught themselves how to repair motor­cycles. Slowly but surely the profits increased and the business developed. At last, Boris had managed to open the money­locker and found bank notes and gold coins inside.

Overcome Culture Shock in the Classroom

    Culture shock occurs in a classroom when students are exposed to a new situation.{#blank#}1{#/blank#}. However, it can also happen to students moving from a small town to a large city, to home－schooled students starting formal school education or to students progressing from one level of education to another. There are several strategies that teachers can use to help students overcome culture shock.

    Make group rules

    Brainstorm(集体讨论) group rules with the class as a whole to create a safe space and good learning environment.{#blank#}2{#/blank#}. Rules could include respecting differences, listening when someone is speaking and not teasing, for example.

    Provide a partner

    Find a partner for the new student in the adjustment period.{#blank#}3{#/blank#}. A good partner is someone who is friendly, outgoing and patient. The partner should show the new student around the school, spend time with him or her after class and eat lunch with him or her.

    Know the source of a problem

    Identify problems early and work with the student and his or her family to deal with them. {#blank#}4{#/blank#}. It can also be caused by overseas or home school environment. Students and parents need to be aware of all the rules and customs that apply.

    {#blank#}5{#/blank#}

    Create lessons that include information about different countries and traditions. These could include story reading, geography, cultural studies and history. Encourage the student to share some information about himself or herself.

A. Create special lessons

B. Respect other cultures

C. They have lost their own language and culture

D. Explain the rules and require everyone to follow them

E. A partner can help him or her quickly adapt to the new environment

F. Classroom culture shock is often caused by the very different environment of a classroom

G. Typically, this happens when a new immigrant(移民) arrives in a classroom for the first time

When it comes to architectural accomplishments, humans like to think they stand at the top. That is to underestimate the astonishing achievement s of social insects; for example, white ants raise skyscraping nests. The true master builders of the insect world, however, are the hundreds of species of stingless bees.

In a new study, Ms. Di Pietro and her colleagues observed over 400 colonies of the stingless bee species in a large bee house in Brazil in 2022 and 2023. Around 95% of the colonies exhibited honeycombs（a structure made by bees） built up in horizontal layers（水平分层）, like tiered wedding cakes, while the rest adopted a spiral（螺旋的） structure.

Since the stingless bee shows a strong preference for a horizontal-layer honeycomb structure, it's surprising that spiral honeycombs occur. The team confirmed that there was no difference in the average cell-building rate between the two styles, and therefore no efficiency advantage.

In order to rule out a genetic explanation for the different styles, the researchers transplanted workers from colonies that built in one tradition to colonies that built in the other, having first emptied the host structures of their native adults. The imported workers soon switched to the local style, which was then continued by the colony's young insects as they eventually matured into workers.

Dr. Tom Wenseleers guessed that the bees may switch styles as a way of coping with the build-up of small construction errors made by their fore-runners. Such a process, in which multiple organisms indirectly affect each other's behavior through the traces they leave in their environment, is known as stigmergy（共识主动性）. The researchers later introduced a sign of spirals to the otherwise perfect horizontal-layer honeycombs, and found that it did indeed cause the bees to switch to building spirals.

These results suggest that stingless bees can pass on different building traditions across generations and individuals needn't be instructed by their peers. "The findings are the clearest demonstration of cultural differences naturally appearing in insects. Insect culture would once have been thought impossible," says behavioral biologist Andrew Whiten, who wasn't involved in the research. "Less than a century ago, culture was thought to be uniquely human."
