Believe it or not, school uniforms are absolutely not only clothes for students. They stand for the culture or beauty appreciation standard of a country. To wear uniforms has become a trend in most countries in modern society. Well, let's take a look at school uniforms in different nations. This will be interesting. And here, you will detect diverse allure (魅力)！

    The style of England school uniforms is rather classic, simple and respectable. Middle school students must wear traditional western-style school uniforms. Boys wear traditional western-style clothes, regular leather shoes and must wear neckties. Girls also wear western-style clothes, regular leather shoes and must wear bow ties. This classic clothing style unconsciously affects England students' temperament(性格)and also sense of beauty.

    Both boy and girl students in Australia are required to wear black leather shoes and white socks. They wear school uniforms all the time except the physical education, when they need to wear gym suits.

    Students in Malaysia obey rather strict rules. Girls' dresses must be long to cover the knees. Shirts must cover the elbow. Comparing with Thai students, they are much more conservative. School uniforms in most schools of China are only different in size. You can't find big differences between boys' uniforms and girls' uniforms only from the appearance. Both of them are loose sport suits.

    Yesterday night, over a dinner with my elder brother's family, a topic of happiness came up. My wife, Marla, a psychologist, was sharing Csikszentmihalyi's concept of “flow” with us. Marla explained that according to the research on flow, people are happiest when they are absorbed in a task that is just challenging enough for them to experience a sense of mastery(熟练).

    A few moments later my brother, Yuri, offered the following opinion: “The first and only, necessary and sufficient factor for happiness is to stop associating happiness with pleasure. The two — happiness and pleasure — have nothing to do with each other.” This morning, with my cup of coffee, I searched through a pile of books on my bedside table and—at the bottom—found a book by Bertrand Russell, I started reading but didn't finish. In it, I found the following thought:

    “The human animal, like others, is adapted to a certain amount of struggle for life, and when by means of great wealth homo sapiens can gratify all his whims (突发奇想) without effort, the mere absence of effort from his life removes an essential ingredient of happiness.”

    The conversation came full circle: people are happiest when they are in a state of flow (Csikszentmihalyi's language )…which is the effortful devotion in a moment…which has nothing to do with pleasure.

    Indeed, as Yuri insisted : happiness–as–pleasure is a myth; the association between happiness and pleasure is nothing but a semantic(语义的) habit; psychologically, the two—happiness and pleasure—are arguably different; and breaking up this association between pleasure and happiness might, in fact, be a powerfully first step in pursuit of happiness.

    As I look back on that exchange, I recall that there was an effort, a struggle to find a common understanding about this seemingly difficult idea—a struggle that made me happy.

    It may surprise bookworms, but apparently masterpieces such as Jane Eyre are lacking in something — sound effects. An electronic-book firm is adding background noises and music to the works of Charlotte Bronte, Sir Arthur Conan Doyle and William Shakespeare in the hope of attracting younger readers. In one example, a description of rain lashing against a window in a Sherlock Holmes story will be“enhanced”with matching noises.

    The first multimedia e-books — with sounds to accompany novels — will be available this Friday in the UK. The Booktrack releases are available to iPad users, with other tablet computer versions to follow. The concept is already in use in the U.S., where the classics come with added sound effects. Readers for example can hear the china cups chinking in Mr. Darcy's garden as they read Pride And Prejudice.

    A story by Booker Prize winner Salman Rushdie will be released later in the year with a specially crafted orchestral score. Rushdie's story In The South will be released with a soundtrack provided by the New Zealand Symphony Orchestra.

    The Power Of Six by Pittacus Lore, a novel for young adults, is one of the first to be tested with a soundtrack which builds in suspense in keeping with the plot. It works by timing the speed of each reader and the software measures the “turning” of a page and moves the music or sounds along accordingly. It has been created by Booktrack which synchronizes (使同步) music to each novel. It is funded by Peter Thiel, a co-founder of PayPal.

    Mr. Thiel said, “It's always exciting to witness the creation of a new form of media. The technology promises to captivate readers in a different way.”

    However, they have been greeted with horror by traditionalists, who say the technology takes away the pleasure of having one's imagination stimulated by a story. They also raise the prospect (预期) of having to ask an overly eager reader to turn their book down. David Nicholls, whose bestseller One Day was recently turned into a film starring Anne Hathaway, said, “This sounds like the opposite of reading. It would be a distraction.”

    The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or m, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother" the real mother or the mother-substitute(母亲替代).

    During the first two weeks of its life warmth is perhaps the most important psychological(心理的)thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother substitutes one covered with cloth 4nd one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their fuvorites. Thereafter they switched and spent most of their time on the mw comfortable cloth mother.

    Why is cloth preferable to bare wire? Something that the Harlows called contact(触摸)comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't “rub" as well as does soft cloth. Prolonged(长时间的)“contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.

    According to the Harlows, the basic quality of baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no nutter how interesting they might be. It screams in terror and curls up into a furry little ball. If its cloth mother it now introduced into the playroom, the baby rushed to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. it then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace(拥抱)as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother.”

Civilization began with agriculture, and though humanity has changed significantly, agriculture remains very important. In certain countries, its significance is more apparent, but the reality is that every country in the world depends on agriculture for one thing or another.

It provides employment. Whether it's working as a farmer, a harvester, a technician for farm equipment or a scientist, there are plenty of jobs available in this field. In developing countries, agricultural jobs help reduce high rates of unemployment.

It's crucial to a country's development. Economic development is tied to a country's agricultural sector. When trade, national avenue, and employment are combined in a positive way, a country enjoys reduced poverty and boosted economic growth. Because strong agriculture results in benefits fairly quickly, focusing on it is one of the best ways to speed up development and improve a country's standing across the globe.

It drives innovation in technology. Because healthy agriculture is so essential to a country's well-being, it's been the setting of some of the most exciting innovations in technology. Through artificial intelligence, blockchain software, and more, scientists and farmers have been figuring out ways to increase crop productivity, use less water, and reduce negative impacts on the environment. For scientists and tech companies, agribusiness is one of the most fascinating and productive fields to work in.

It's the source of our food supply. Arguably, the most important aspect of agriculture is that it's the source of the world's food supply. No matter where or what you are eating, the ingredients in your meals come from somewhere. All roads lead to agriculture. In countries dealing with food insecurity and severe malnutrition, their agricultural sectors are suffering. When agriculture thrives(蓬勃发展), fewer people go hungry.

It can help heal the environment. Agriculture possesses the power to cause harm or heal. When farmers prioritize biodiversity on their land, it benefits the earth. Having more biodiversity results in healthier soil, better water conservation, and healthier pollinators(传粉者).

All in all, agriculture plays a critical role in the entire life of a given economy. Agriculture culture is the backbone of the economic system of a given country.

It is very small, but it is really helpful. It can help you keep away from viruses (病毒) . You must bring it with you very often these days. 1 is it? Of course, it is a mask (口罩). To make masks fun and easy to wear, people around the world think of many interesting and special 2 .

Wear a smile

Masks cover (遮盖) our faces, 3 they can't cover our smiles. A French company makes masks with smiles on 4 . You can still show your smile to 5 when you go out.

Eat with me

A 6 in Japan teaches people to make special masks. When eating or 7 , people can change their masks in half. Look! A napkin (餐巾纸) is on the mask. People can put a spoon into their mouth. The napkin 8 like a mask to stop viruses.

Let's be fashionable

Fashion brands (品牌) make some beautiful masks. Look at this one. The mask is full of beautiful pictures 9 many flowers. Butterflies are flying around the flowers. Does it make you think of a beautiful garden? It can make you 10 and bring you great fun.
