A beach town in the US state of New Jersey recently passed a ban on trousers, jeans and shorts that hang less than 3 inches below the hips(臀部) for an excuse of being unfriendly to others' eyes. But besides those low-hanging pants, here are some other items of popular travel clothing that may also need to be banned.

    Thai Fisherman Pants: These lightweight cotton pants, wide in the waist and originally designed for Thai fishermen, are popular among men and women due to their comfort, ability to last long and relative ease of wearing. But the bad news is that wearing these pants isn't the way to be respected in Bangkok.

    “Wearing them to wander around the town is considered 'low class' (even if we don't say it out loudly),” wrote a local Bangkok woman, who called herself “Beebah” on line. “It's better to dress ‘respectable' if you want to be treated well. Even a T-shirt and shorts are better than fisherman pants and tight sleeveless shirts. If you really love them, wear them at home.”

T-shirts with slogans: Wearing T-shirts with slogans in the local language on them may seem cool to some young tourists who are swept up in the excitement of being in a foreign country for the first time. But be careful as they could be some meaningless words and make you look really stupid. What's worse, some slogan T-shirts are political--you might get yourself into trouble without even knowing about it.

    Croce(洞洞鞋): Comfortable and easy to slip on and off, Crocs have been go-to-beach shoes for many tourists. But we must admit that these holey plastic shoes are deadly ugly in every way. “Supporters would hold that the comfort of the Crocs is over their looks, but Babyclothes are comfortable, too. Your don't feel the need to walk around in them, do you?” said a friend of mine.

    La Tomatina, Spain

    Tomato juice flows through the streets of Bunol on the last Wednesday of August as the worlds largest tomato fight happens. Festivities begin in the town square where there is a huge pole covered in soap and with a leg of ham at the top. Participants try to climb up the pole to get the ham as watchers throw buckets of water to them. After a gun is fired to signal the beginning of the fight, people catch the tomatoes and throw each other in the streets until the gun sounds again, marking the end of the event.

    Holi, India

    This spring festival is celebrated throughout the country in late February or early March. The two-day event celebrates the legend of Prahlad, who escaped unharmed from the fire of the evil Holika Dahan. People mark the event by lighting fires and throwing colored powder on one another Children load colored water into toy pistols called pichkari and take aim at passers-by. Holi is known as a happy celebration of the victory of good over evil.

    Burning Man, Nevada

    This infamous festival began in 1986 with the burning of a large figure to mark the summer solstice (夏至). It's since grown into a week-long annual event that draws more than 48,000 people to the Black Rock Dessert. It is held during the week before Labor Day. Participants set up camp in the desert to celebrate art.

    Songkran, Thailand

    This festival marks the Thai New Year, which is celebrated in the second week of April. This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管) and water guns to celebrate the event.

    An autonomous vehicle designed for making local commerce deliveries was unveiled by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four exterior compartments (暗格) — two on each side — to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.

    “We can use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson said. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery isn't fast enough for some customers.”

    Nuro isn't alone in building robots for local commerce deliveries. Earlier this month, Toyota, a Japanese car company, unveiled a concept vehicle that could be used for package delivery. A handful of startups — including Starship Technologies, Marble and Dispatch — are testing small robots for deliveries on sidewalks.

    Nuro's vehicle will likely face legal hurdles. Fully autonomous vehicles without a test driver aren't legal in California today, and many companies have shifted testing to states where regulators are more welcoming of autonomous vehicles, such as Arizona.

    Nuro expects to face fewer challenges because it doesn't carry passengers. Nuro's narrow size may also be helpful when navigating streets and avoiding pedestrians. The vehicle isn't equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car's next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes it's better to make sure the car performs predictably, so that human drivers know what to expect from it.

    “We feel by creating this new technology that's going to enable this last mile delivery, we're going to be creating new markets and doing things that previously weren't possible,” Ferguson said. “This is not swapping out Jobs with robots. It's creating new markets. There will definitely be new employment opportunities.”

How to Become a Lifelong Learner

    Learning doesn't stop just because school does. Making a commitment to yourself to learn something new every day, you will not only enjoy what you discover, but you will be able to apply your knowledge and become a teacher to future generations. Here are some steps to become a life­long learner. 

    Learn how you learn.{#blank#}1{#/blank#}Note what learning techniques are most efficient for you and use them as much as is practical, such as viewing online tutorials on websites like YouTube if you're more of a visual learner. 

    {#blank#}2{#/blank#}Try many different things so that you don't box yourself into believing you're only good at a few things. It's probable that you're good at many things, but you won't know until you've tried. 

    Look at learning as an exploration and opportunity, not a chore (琐事)．Don't just force yourself to learn things because they are important or necessary. {#blank#}3{#/blank#} Follow your heart, as well as your sense of duty. Do you remember the 8th grade history that you hated so much, with all those names and dates that seemed to mean nothing? The point was to bring you to learn details now, which will knit chunks of information together later.{#blank#}4{#/blank#}   

    Read, read, read.{#blank#}5{#/blank#}Reading is a gateway into other worlds and into the minds of your fellow human beings. And reading will help you to learn the discoveries and mistakes of others who have gone before you; reading is, in effect, a shortcut so that you don't have to learn things the hard way. 

A．Learn where your talents and interests lie.

B．It was a chore then, but it makes sense, now.

C．Recognize the educational value in whatever you read.

D．Determine your own preferred learning style or styles.

E．Their ways of learning might help you to improve your own.

F．Make friends with your local library and new and used book sellers.

G．Instead, learn things that you need to learn alongside things you love to learn.

Help your child look forward to school

    Your child says that he is sick whenever the alarm clock goes off. Your child hides under the covers and cries, "I hate school" when it's time to get ready in the morning. {#blank#}1{#/blank#} If he behaves like that, there could be more than book reports and tests making him want to stay at home.

Talk to your child

    You can ask questions like "Did you have a good day today?" or "{#blank#}2{#/blank#}" If your child rides the bus, you can ask where he sits and why.

Talk to the teacher

    Meet with your child's teacher. Discuss the problems you are having at home and find out what is happening at school. Are there behaviour problems you do not realize? {#blank#}3{#/blank#}

Be aware

    Your child's problem may also be caused by a learning disability. If you think there's such a problem, talk to the school.{#blank#}4{#/blank#} Most schools have either an in-house psychologist (心理学家) or one who visits the school regularly. Set up a time to discuss the problem with his teachers.

{#blank#}5{#/blank#}

    If your child's homework is untidy, don't criticize (批评) his handwriting. Instead, praise him for completing the work. If his clothes don't match in the morning, tell him how proud you are that he got ready for school on time instead of criticizing him.

A. Look for the good.

B. Volunteer in the classroom.

C. Do other students make fun of your child?

D. How are you getting along with your classmates?

E. You might get angry when your child tell lies at school

F. Your child forgets to bring home his homework on purpose.

G. His teachers will pay more attention to while he's in class.

    My college experience included this life-skill lesson: Drink alcohol on a full stomach. Or you will get inebriated too quickly. Of course, most college students shouldn't be drinking at all, but we know from the National Institute on Alcohol Abuse and Alcoholism that close to 60 percent of college students aged 18 to 22 do consume alcohol, which makes harm-reducing approaches important.

    Unfortunately, campus authorities and researchers are reporting a practice that turns the full-stomach drinking strategy on its head: rather than filling up before a night of partying, significant numbers of students refuse to eat all day before consuming alcohol.

    This is a high-risk behavior called "drunkorexia," which is one part eating disorder, one part alcoholism—a very dangerous combination for college-age students. The term drunkorexia, which can also include excessive exercise or purging before consuming alcohol, was coined about 10 years ago, and it started showing up in medical research around 2012. Drunkorexia addresses the need to be the life of the party while staying extremely thin, pointing to a flawed mind-set about body image and alcoholism among college students, mostly women.

    Imagine this scenario: A female college freshman doesn't eat anything all day, exercises on an empty stomach, then downs five shots of tequila in less than two hours. Because there's no food in her system to help slow the absorption of alcohol, those shots affect her rapidly, leading to inebriation and possibly passing out, vomiting or suffering alcohol poisoning. That's drunkorexia.

    Tavis Glassman, professor of health education and public health at the University of Toledo in Ohio, researches drunkorexia and worries about scenarios such as the one described above: "With nothing in her system, alcohol hits quickly, and that brings up the same issues as with any high-risk drinking: getting home safely, sexual assault, unintentional injury, fights, hangovers that affect class attendance and grades, and possibly ending up in emergency because the alcohol hits so hard," he says.

    "Alcohol can negatively affect the liver or gastrointestinal system, it can interfere with sleep, lower the immune system and is linked to several types of cancers," Hultin says.
