Often in Scotland it can feel like the only difference between summer and the rest of the year is that it doesn't snow. (This isn't a guarantee!) But when the weather is good, it's a truly special place-here are some things you can do in summer when the weather is nice.

    See

    With the richest wildlife across the UK, take the chance to see some of the less common sites. On the West coast of Scotland there are lots of places where you can take a boat trip to see many kinds of whales. If you prefer dolphins, you can see the most northerly colony of bottlenose dolphins (海豚) in the world just off Inverness in the Moray Firth. Of course it's likely that you'll see seals (海豹) and many other animals on these trips too.

    Do

    The waves of Thurso right in the north of Scotland are just great. If you're not feeling brave enough to go in the water and prefer to watch from the safety of the shore then there're several major surf contests held there.

    Another very Scottish activity ideal for good weather is “Munro Bagging”. Named after Sir Hugh Munro, the 218 mountains in Scotland over 914m high are called Munros and walkers try to see how many they can climb in a set amount of time. This is not easy though-conditions can change suddenly and many of the routes are very tough (艰难的).

    Eat

    Thanks to a large Scottish-Italian population, there are too many specialist ice cream sellers. One of the most famous of them is Nardini in Largs, Ayrshire. Not only can you watch people actually make ice cream but you can sit and eat in a beautiful refurbished (翻新的) 1930s building facing the river Clyde. There's even a piano player at the weekends.

    Think of a seed buried in a pot. It's dark down there in the potting soil. There's no light, no sunshine. So how does it know which way is up and which way is down? It does know. Seeds send shoots up toward the sky, and roots the other way. Darkness doesn't confuse them. Somehow, they get it right.

    More surprisingly, if you turn a seedling (秧苗) or a whole bunch of seedlings upside down, as Thomas Andrew Knight of the Royal Society did around 200 years ago, the tips and roots of the plant will sense, “Hey, I'm upside down. Look! I. will turn my way to the right direction and do a U-turn.”

    How do they know? According to botanist Daniel Chamovitz, Thomas Knight about 200 years ago guessed that plants must sense gravity. Knight proved it with a crazy experiment involving a spinning plate.

    He attached a bunch of plant seedlings onto a disc. The plate was then turned by a water wheel powered by a local stream at a speed of 150 revolutions (旋转) per minute for several days.

    If you have been at an amusement park in a spinning teacup, you know that because of centrifugal force (离心力) you get pushed away from the center of the spinning object toward the outside.

    Knight wondered, would the plants respond to the centrifugal pull of gravity and point their roots to the outside of the spinning plate? When he looked, that's what they'd done. Every plant on the disc had responded to the pull of gravity, and pointed its roots to the outside. The roots pointed out, and the shoots pointed in. So Thomas Knight proved that plants can and do sense the pull.

    Cultural rules determine every aspect of food consumption. Who eats together defines social units. For example, in some societies, the nuclear family is the unit that regularly eats together. The anthropologist Mary Douglas has pointed out that, for the English, the kind of meal and the kind of food that is served relate to the kinds of social links between people who are eating together. She distinguishes between regular meals, Sunday meals when relatives may come, and cocktail parties for relatives and friends. The food served symbolizes the occasion and reflects who is present. For example, only snacks are served at a cocktail party. It would be inappropriate to serve a steak or hamburgers. The distinctions among cocktails, regular meals, and special dinners mark the social boundaries between those guests who are invited for drinks, those who are invited to dinner, and those who come to a family meal. In this example, the type of food symbolizes the category of guest and with whom it is eaten.

    In some New Guinea societies, the nuclear family is not the unit that eats together. The men take their meals in a men's house, separately from their wives and children. Women prepare and eat their food in their own houses and take the husband's portion to the men's house. The women eat with their children in their own houses. This pattern is also widespread among Near Eastern societies.

    Eating is a metaphor that is sometimes used to signify marriage. In many New Guinea societies, like that of the Lesu on the island of New Ireland in the Pacific and that of the Trobriand Islanders, marriage is symbolized by the couple's eating together for the first time. Eating symbolizes their new status as a married couple. In U.S. society, it is just the reverse. A couple may go out to dinner on a first date.

    Other cultural rules have to do with taboos against eating certain things. In some societies, members of a family group, are not allowed to eat the animal or bird that is their totemic ancestor. Since they believe themselves to be descended from that ancestor, it would be like eating that ancestor or eating themselves.

    There is also an association between food prohibitions and rank, which is found in its most extreme form in the caste system of India. A caste system consists of ranked groups, each with a different economic specialization. In India, there is an association between caste and the idea of pollution. Members of highly ranked groups can be polluted by coming into contact with the bodily secretions, particularly saliva(唾液),of individuals of lower-ranked castes. Because of the fear of pollution, Brahmans and other high-ranked individuals will not share food with, not eat from the same plate as, not even accept food from an individual or from a low-ranking class.

    Millions of people all over the world use the word okay. In fact，some people say the word is used more often than any other word in the world.

    It may be common，but no one can seem to agree on how the “OK” came to be.

    Okay means “all right” or “acceptable”. It expresses agreement or approval. You might ask your brother，“Is it okay if I borrow your car?” Or if someone asks you to do something，you might say，“Okay ， I will.” Still，language experts do not agree about where the word came from.

    Some people say it came from the Native American Indian tribe known as the Choctaw. The Choctaw word “okeh” means the same as the American word okay. Experts say early explorers in the American West spoke the Choctaw language in the nineteenth century. The language spread across the country.

    But many people dispute(不同意)this.

    Language expert Allen Walker Read wrote about the word okay in reports published in the 1960s.He said the word began being used in the 1830s.It was a short way of writing a different spelling of the words “all correct.” Some foreign-born people wrote “all correct” as“o-l-l k-o-r-r-e-c-t.” and used the letters O.K.

    Other people say a railroad worker named Obadiah Kelly invented the word long ago. They said he put the first letters of his names—O and K—on each object people gave him to send on the train.

    Still others say a political organization invented the word. The organization supported Martin Van Buren for president in 1840.They called their group，the O.K. Club. The letters were taken from the name of the town where Martin Van Buren was born—Old Kinderhook，New York.

    Not everyone agrees with this explanation，either. But experts do agree that the word is purely American. And it has spread to almost every country on Earth.

Each day, 10-year-old Seth asked his mom for more and more lunch money. Yet he seemed skinnier than ever and came home from school hungry. It turned out that Seth was handing his lunch money to fifth grader, who was threatening to beat him up if he didn't pay.

Most kids have been made fun of by a brother or a friend at some point. And it's not usually harmful when done in a playful and friendly way, and both kids find it funny. But when teasing becomes hurtful, unkind, and constant, it crosses the line into bullying and needs to be stopped.

Bullying is intentional torment(折磨)in physical or psychological ways. It can range from hitting, name-calling and threats to blackmailing(勒索)money and possessions. Some kids bully others by deliberately separating them and spreading rumours about them. Others use social media or electronic messaging to make fun of others or hurt their feelings.

It's important to take bullying seriously and not just brush it off as something that kids have to tolerate. The effects can be serious and affect kids' sense of safety and self-worth. In severe cases, bullying has contributed to tragedies, such as suicides and school shootings.

Kids bully for a variety of reasons. Sometimes they pick on kids because they need a victim—someone who seems emotionally or physically weaker, or just acts or appears different in some way—to feel more important, popular, or in control. Although some bullies are bigger or stronger than their victims, that's not always the case.

Sometimes kids bully others because that's the way they've been treated. They may think their behavior is normal because they come from families or other settings where everyone regularly gets angry and shouts or calls each other names.

Unless your child tells you about bullying—or has visible injuries—it can be difficult to figure out if its happening.

After releasing a short video on April 27 about planting and cooking peas, Chinese food blogger Li Ziqi witnessed her followers on YouTube go beyond 10 million.

This puts Li, who shot to fame with short videos recording her traditional and peaceful lifestyle in China's countryside, among the ranks of the most popular Chinese-language content creators on the platform.

"It's really surprising. I didn't expect such a wide response," Li told Xinhua in an interview, noting she was surprised by how foreign fans were taken with her works. "What I present is just a lifestyle I've long followed and appreciated," she said. "Maybe it's also what many other people have valued."

Li's YouTube videos center on her life with her grandmother in the rural parts of Sichuan Province. In the videos, Li, often dressed in graceful traditional dresses, rises at sunrise, rests at sunset, plants seeds and harvests flowers, cooks Chinese dishes and crafts bamboo furniture. Unlike many other food bloggers, Li's videos set China's countryside as the stage and start with how the foods are planted and harvested on the farm. She rarely speaks in the process.

Li's overseas followers have praised her videos for showing the amazingly charming, simple and beautiful side of China's rural life, but back home, there have long been debates on whether her presentation is unrealistically poetic.

In response, Li, who was raised in the countryside, said she never needs special arrangements when shooting a video about rural life as "everything is in my mind." "In the countryside, planting flowers, vegetables and trees is not difficult. There are tough elements of rural life of course, but I didn't put them in my videos," Li said. "Most people today are facing much stress in work and life, so I hope they can feel relieved and relaxed when watching my videos."
