This Sunday in London, an American running phenomenon will hit the UK for the first time — and looks set to leave a mark. The Color Run™ series, founded in 2011 by Utah resident Travis Snyder, who currently lives in Los Angeles, is a 5k with a twist: runners start in white clothing, and at each kilometer get caked in brightly colored powders (made from 100% eco-friendly and natural food-grade corn starch) thrown by volunteers.

    Snyder, 35, previously organized rock climbing events but says it was having a child that inspired him to think of an event combining fitness and pleasure. So far,  600,000 people have already taken part in Snyder's fitness festivals across the world, from Sydney to Rio de Janeiro, becoming America's biggest 5k along the way.

    What does Snyder think is its appeal? "I think sometimes people get tired of being so competitive," he says. "In a running event, the person next to you is the tool that you are going to compare yourself to; whether or not you run faster than them or they run faster than you. The Color Run still has running in its basis: people still get to be out and be active. But instead of it being an exclusive experience, it's an inclusive experience, where the people next to you are part of that."

    The events attract a large population, including families and children, along with a higher proportion of women than most runs. For many, it is their first race and furthest distance. Synder's eight-year-old son has taken part in 20 of the races. "It's not a big deal because he doesn't think of it as 5k – he is just running and having fun."

    In line with this theme of participation rather than competition, there are no praises for coming first. If runners want to get a result, they will have to track it themselves, as it is not officially timed. And, needless to say, the finish line is one big party – before the clean up begins.

    If you want to be happy, you must take responsibility and stop expecting things or people to make you happy. You are the source of your own happiness, so stop looking elsewhere. {#blank#}1{#/blank#}. Here are a few ways for you to follow:

    Be thankful to others. {#blank#}2{#/blank#} It is too easy to take those around us for granted. Show them the same consideration you would like shown to you.

    {#blank#}3{#/blank#} This goes beyond(超过) politeness; it is a form of giving. Treat everyone you meet as if they have a big sign on their chest saying “make me feel important.” If you do this you will discover a hidden source of joy.

    Perform acts of kindness. Don't wait to be asked, {#blank#}4{#/blank#} It doesn't need to be a big thing, hold the door for a stranger, or smile at anyone you make eye contact with. Look for chances to make others feel good.

    Make a decision to be happy. This is the most important step on the road to a happy life. {#blank#}5{#/blank#} You are the key to your own happiness, so go ahead, unlock it once and for all.

A. Respect other people.

B. Be polite to other people.

C. Instead of looking for happiness, start creating it.

D. You can change your feelings by acting the way you want to feel.

E. If you see a chance to do something nice for someone else, do it!

F. Simply make up your mind to be the happiest person you know, and you will be.

G. Be grateful to the people in your life, and practice saying thank you for any politeness they show you.

    What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to do well at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most just but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

    Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery (烹饪术) and look for a job where you can improve these skills.

    If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

    Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle (运用) tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognise that you will have a chance of a fresh start at work.

    It is often necessary to release a fish, that is, set it free after catching, because it is too small, or you just don't want to take it home to eat. In some cases, releasing fish is a good measure that will help keep fish variety and build their population size. The Department of Game and Inland Fisheries (DGIF) encourages fishermen who practice catch-and-release fishing to use a few simple skills when doing so. The advice provided below will help make sure that the fish you release will survive to bite again another day.

    —When catching a fish, play it quickly and keep the fish in the water as much as possible. Don't' use a net in landing the fish and release it quickly to prevent it from dying.

    —Hold the fish gently. Do not put your fingers in its eyes. Don't wipe the scales (鱼鳞) off the fish because it might cause it to develop a disease and reduce its chance of survival.

    —Remove your hook (鱼钩) quickly. If the hook is too deep or hooked in the stomach, cut the line and leave the hook in. The hook left inside will cause no serious problem to the fish.

    —Take good care of the fish by moving it gently in water. Release the fish when it begins to struggle and is able to swim.

    —Do not hold fish in a bucket or some other containers and later decide to release it. If you are going to release a fish, do so right away.

    With a little care and by following the suggestions given above, you can give the released fish a better chance of survival.

    Nowadays six Amazon Scout delivery robots rolled out in a pilot program in Snohomish County, Wash. The robots carry meals, groceries and packages to homes and offices in this region just north of Seattle. They have appeared on the sidewalks of London, Beijing and other cities and communities worldwide. These machines must overcome pedestrian legs, naughty dogs and broken pavement, which raises some questions.

    These services are gaining attraction as a growing number of city residents expect immediate or scheduled delivery for just about everything. Between 2017 and 2018 online retail sales in the U.S. increased by 16 percent. On the final step of all these deliveries, called the last mile, humans on bicycles, motorized scooters (电动车) or large delivery trucks typically deliver packages. All the vehicles compete for space on busy urban streets. "Deliveries are trending upwards in all crowded city centers, and if city and state leaders don't start thinking about creative solutions like robot deliveries, we can expect even worse traffic jams," says Paul Mackie, director of a transportation policy research center in Arlington.

    A study by this center found 73 percent of delivery vehicles in Arlington were parked outside of authorized areas, often blocking bike lanes and crosswalks. By moving the last step of deliveries from the road to the sidewalk, cities could reduce traffic jams and solve the parking problem entirely, Mackie says.

    Companies such as Amazon are not developing this delivery technology simply to clear up urban traffic. Self-driving vehicles and sidewalk robots could cut down last-mile delivery costs in cities by as much as 40 percent, according to a 2018 report by a consultancy firm. A delivery robot can cost thousands of dollars to manufacture, and most currently require human management and conservation. But in the long run companies that use autonomous delivery vehicles in the next several years could end up saving billions of dollars, the report stated.

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.
