I guess everyone would like to set off for a journey with someone we can understand and have fun with. Travelling with a companion(同伴) is great!
It’s good to have someone with you who can watch your backpack when you want to use the toilet, find the way back home when you get lost, carry some of your luggage when you’re tired, take some photos of you when you want and help you in all kinds of situations. The feeling of having someone by your side makes you feel less stressful about many things.
With a companion you can together share the beautiful moments during the travels, experience the same things in a different way and support each other. It’s much more interesting and exciting when you have the chance to share something with someone while on your road. Meanwhile, there is always someone whom you can shout at when you are angry, or a shoulder on which you can cry when you miss your home.
A companion can share the costs with you. You can stay in one room, buy a dinner, have it together and share the bill, etc. It’s good to travel with someone who has the same or similar pattern of payment as you so you can support each other without having any arguments.
Having a companion by your side when travelling means less loneliness. You don’t think about it unless you get left in the middle of nowhere, far away from your friends and family. Then you wish to have someone with you.
In short, travelling with someone is the best choice for people who are short of travel experience. We might sometimes feel like being on our own and enjoy the sights with nobody behind our back but at the end of the day you have much more fun when being with someone, especially for a long run.
China Needs To Fight Its Massive Food Waste To Combat Climate Change
China is facing a massive food waste crisis. Over 6% of China's total food production is already lost before reaching consumers, and restaurants in Chinese cities throw away an average of a third of food served. Amid the climate crisis and an already vulnerable global food system exposed by the current Covid-19 pandemic, it is vital to tackle food waste in Asia's largest country.
Asia currently drives over half of global food waste, and China is one of the leading countries contributing an enormous amount of discarded food each year. According to a recent report conducted by the World Wildlife Fund (WWF) and local NGO partners, Chinese cities produce 25% of the world's municipal solid waste - most of which is food. When examining restaurants and school canteens, data showed that one third of all the food served is thrown away.
Why does food waste pose a massive challenge to the planet? Besides global hunger, the way that food waste is managed contributes to driving climate change. Much of the China's food waste ends up in landfills, which contributes significant amounts of methane, a major greenhouse gas that causes global heating. Scientists have found that every kilogram of landfilled solid waste releases its equivalent(同等的)weight of carbon dioxide equivalent（等价物）.
With cities contributing to the most food waste in the country, they need to be at the front lines to address the problem. Projects across other cities in Asia can serve as examples on how to reduce food waste, such as Singapore's Lumitics, a tech-forward startup, which has created a food waste tracker that can attach to bins in commercial kitchens. The product aims to help F & B and hospitality businesses analyze the type of food that is being thrown away the most in order to launch a targeted campaign to reduce the amount of discarded food.
But let's be clear - food waste is not a problem in China or Asia alone. With over 10% of annual global carbon emissions coming driven by food waste, the entire world needs to step up its efforts to fight the issue.

Human beings are smart. However, it seems that people are gradually losing their smartness as smartphones become more and more important assistants in their lives, reported news website Record Japan on Oct. 22. As we rely too much on technology instead of our brains, many people have lost three basic abilities, said the website.
The first skill many people have lost is remembering phone numbers. Because phone numbers are stored in smart phone contacts, there's no need to dial a number or look at it again.
And some people may also have lost their sense of direction because navigation apps can guide people anywhere they want to go. These apps can even find shortest routes for you and avoid traffic jams. But the worst lost skills may be social ones, meaning that some people are becoming socially inept(无能的）. People often bury themselves in their smart phones. As we're too addicted to what's happening in the virtual world, some of us have lost conversational skills and sometimes can't even tell whether a person is happy or not.
In August, researchers at the University of California, Los Angeles, studied 51 students aged 11 and 12 who had over five hours' screen time every day. Their task was to tell the emotions of 48 pictures of faces that were happy, sad, angry or scared. The children made an average of 14.02 mistakes at the beginning. But after a five-day camp without electronic (电子的) products, they made only 9.41 mistakes on average. “If you’re not practicing face-to-face communication, you could be losing important social skills,” concluded professor Yalda Uhls from the research.
Luckily, people still have a chance to get these abilities back. You should try to keep your parents' numbers in mind for emergencies. You should also pay more attention to street signs and stores, which will help you to draw a mind map and stop you from getting lost. And the easiest solution to social skill loss is to take a break from electronic devices because we are social creatures. We need device-free time.

There are many benefits of public transportation. For example, public transportation makes it easier for people to get where they want and need to go. It also helps people save money, as the cost of maintaining a working vehicle is often much more than the cost associated with public transportation. The frequency of traffic jams and accidents may also be reduced when a person uses public transportation.
One of the main benefits of public transportation is the fact that it makes it easier for people to get around. Without public transportation, many people — especially those without cars — would be limited in where they could go and what they could do. With public transportation, however, people can get to school and work, get to the grocery store and to doctors’ offices, and visit relatives, even if they do not own vehicles. Public transportation serves people of all ages and from all walks of life, ranging from families, including their children, to business people on their way to the office, to the elderly.
Often, people complain about the cost of public transportation when the rates are raised. When compared to the cost of buying a car, many people find that choosing to ride public transportation is a much cheaper option.
When public transportation is available, many people choose to use it instead of driving to work and school. This is true even of many people who own cars, as they may prefer to ride to work on a bus or train rather than deal with traffic jams and parking frustrations each day. When people make this choice, the result is less traffic on the roadways, which means fewer traffic jams and less pollution. In fact, the choice many people make to ride public transportation may even translate into fewer car accidents and vehicle-related deaths and injuries. Additionally, the use of public transportation also means less gas is consumed each year.

Teenagers' fitness is now a major concern and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong and helps you to keep the right body weight. Sports scientists offer the following advice to teenagers: First, find out your present level of fitness. Then you can design a programme that will help you become healthier.
There are three levels of fitness that need a change of lifestyle. ''Overweight'' means that the person gets very little exercise and often has a serious weight problem. ''Inactive'' means that the person does not join in many physical activities, but is not seriously overweight. ''Active'' refers to people who take part in sports and other physical activities, but do not have a high fitness level.
According to experts, overweight teenagers should work out to keep healthy. Ride a bike, play volleyball or basketball for a while, and go for a twenty-minute walk each day. All these will help to burn calories. Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push-ups and sit-ups, starting with twenty of each a day. Inactive people can take a little more exercise than overweight people because their bodies are stronger. The same rule is also suitable for active teenagers.
Experts also suggest one hour a week or more on running and other forms of intensive exercise, together with fifteen minutes a day spent on stretching and bending activities. They are really important in order to prevent injuries. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase the person's strength.

Artificial intelligence(AI)teachers can provide customized teaching for students to meet their unique requirements through analyzing data and deep learning.In the future, they may replace human teachers for basic teaching tasks.Since some students may find it and put new power into traditional teaching patterns.An educational system providing customized teaching centered on students represents the future trend of AI education.
China's AI education has developed rapidly in recent years with the rise of several thousand relevant companies.Currently,AI teachers are able to help students leamn pronunciation,analyze their condition,guide them to learn independently,and even grade writing assignments. Some foreign AI educational systems have been introduced into several domestic schools and have worked well on trial.
However,the promotion of AI education is still facing several difficulties in practice such as low technological levels,inadequacy of data and lack of funds.AI education still depends largely on human teachers' work.Most importantly,it conflicts with current educational patterns because the courses developed by foreign countries are not suitable for Chinese exam-oriented education.Teachers may also find it hard to change their original roles in classrooms since easing control on classes may make them seem irresponsible.These problems need to be handled before the mass promotion of Al education.
With AI teachers,the original teacher-centered classes will be transformed into student-centered ones where teachers only organize the class and provide guidance.Since teachers are supposed to not only equip students with knowledge but also shape their values and help them develop creative abilities,AI teachers will not replace human teachers but will only pose higher requirements of teaching.A combination of AI teachers and human ones can create the best future for Al education.

If you're worried that too much “screen time ”could badly influence your child's intelligence， new research suggests you might be right. By analyzing the data gathered from over 4，500U. S. kids aged 8 to 11 between 2016 and 2017，Jeremy Walsh，a postdoctoral fellow with the CHEO Research Institute in Ottawa， found that too much “screen time” could be harming your child's intelligence.
Kids with the sharpest intellects spent less than two hours a day on their cellophanes， tablets and computers coupled with 9 to 11 hours of sleep and at least an hour of physical activity. Too much screen time could be affecting kids ability to focus， especially if they are switching between apps on a device or between different screens at the same time， Walsh suggested. “ One leading theory is that much time on screens is spent multitasking using multiple apps or devices at once，” he said. “This can interfere with a child's ability to focus and keep interest on a task. It can be damaging the building blocks for good cognition(认知).”
Sleep is important for brain development， since that's when the brain reorganizes itself and grows， Walsh added. Besides， exercise has been shown to increase blood flow to the brain and oxygenation of brain tissues， and increases the connectivity of networks in the brain. Too much screen time could lead to a“ cascade”(瀑布) effect where kids don't get enough sleep and then are less active during the day.“ You can see how this would have an impact on brain health，” Walsh said.
What should parents do? Walsh advised setting firm rules about the use of screens including how long children are using the screens， the kinds of apps they are using and how many screens they are using at once. Concerned parents also should preview games or apps before letting their child play， seek out more interactive(交互的)options that engage the child's mind， and use parental controls to block or filter content and limit screen time.

Getting up early has been regarded as a good habit since ancient times. Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day. So, getting up early is of great importance to us all.
In fact, morning is the best time of a day. In the morning, the air is the freshest and people are usually in the best conditions. Many of us may have the experiences that we memorize some things more quickly and accurately in the morning than at any other time of the day.
Additionally, if we get up early and do some morning exercise or only take a short walk in the morning, without doubt we can build our bodies and become much healthier. That is why many people getting up early do physical exercise year after year.
We will also have enough time to make a plan and get ready for our work or study of the day if we get up early. For example, if everyone in the family gets up early, we will have enough time to prepare the breakfast for the whole family. Children will have enough time to catch the school bus, and husband will never forget to change his dirty shirt. Everything is in order. What a harmonious scene! However, if we get up late, we will probably have to do everything in a great hurry, making it in a mess.
Let us remember getting up early is a good habit. If you are a late riser, you may find it difficult to form the habit of getting up early. You will have to make efforts to do so. If you want to get up early, sleeping earlier the night before expect to be successful. Besides, you can set your alarm clock or ask someone who you know will be awake at that time to call you. If you stick to getting up early every day, you will certainly benefit a lot from it.
