Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic (存在问题的) victory. First-time success is usually a fluke (侥幸). First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “She who has broken many pots.” If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and burn scars. They knew how much credibility (可信) their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist (荡秋千演员). She spent three years practising a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. And if she was bored, there was no point in subjecting (使……服从于) her body to all that stress. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time. I hope I can tell her, though, that it's not the end of the world. Indeed, with luck, it is the beginning.

    When people ask me to name typical British dishes,I have,however,struggled to think of an answer.Yes,we do have our own national dishes.We do have fish and chips,and we have other dishes like roast dinner and shepherd's pie.But how much do we actually eat them?

    Fish and chips,is made up of battered（绞碎的）fish and chips,which is often accompanied by a thick paste（酱）. The majority of British people really do love this dish but it is not something that we would eat,say,on a weekly basis.It's also not usually something that we would cook at home.The British people associate this dish with the seaside and it's something that will usually be eaten on a day trip there,bought from a takeaway fish and chip shop.

    Another favourite British dish is roast dinner.This is made up of roast meat,usually chicken or beef, accompanied by roast vegetables and a meat sauce called gravy（肉汁）.It is usually eaten on a Sunday,perhaps for a special family dinner.It can either be cooked at home or eaten in a traditional pub.We also eat a more elaborate version of this for our Christmas dinner.

    Although we do have our traditional dishes,our diet has been greatly influenced by other countries.You can find a wide range of international foods in the supermarket or varieties of different restaurants on our high streets.A famous saying amongst British people is that our national dish is now chicken tikka masala,a dish which is heavily influenced by Indian cuisine.

    Don't expect to be served a traditional dish if you ever get invited for dinner at a British family's home!

    When one of your car tires goes flat, there are two things you can do, you can complain and change it or, if you don't have a spare, stand helplessly beside the road and hope someone comes to your rescue. Now comes a third choice, called Quickwheel. It is designed to get disabled motorists rolling again as quickly as possible.

Quickwheel is basically a tiny emergency trailer—complete with three tough little wheels of its own-- that supports the flat tire and enables the motorists to drive to a service station without losing much time or expending much energy. The product is made in the US. Company, Quickwheel Inc. of Greenwich, Connecticut. According to the firm's president, Robert Bockweg, the product meets each of the major worries that customers relate with flat tires: safe, lost time and physical labor.

    To use it, motorists simply unfold the product to its fully extended position, set it in front of the disabled tire, drive the car onto the Quickwheel's ramp (斜板) and fix a special safety strap over the tire. The tire is then locked in Quickwheel's metal frame. Its three wheels do the rest of the work. According to Quickwheel Inc, its product can be driven “for miles” at the speed of up to 45 miles per hour “without any noticeable change in the vehicle's braking or steering operation”. The company also says that it can be used on just about any type of car, jeep, mini-van or trailer. (拖车)

    Bockweg says that Quickwheel will be sold first in the United States, at a price of 150 dollars. Sales agreements now being talked over should make the product ready for use in Japan, Canada and Western Europe in the near future.

    For centuries, dolphins have got our admiration, and it is easy to see why. They are beautiful, cute and smart sea animals. Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way, they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. It is said that dolphins are the world's second brightest creatures after humans and have many brain features related to intelligence. Their brain is nearly the same size as our own, and they live a long time at least twenty or thirty years.

    Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.

    Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.

    There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.

    Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

    On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, "You're nervous and that's okay. Everyone is afraid of high school." I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends.

    On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be? I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it!

    Despite my fears, after the first week I finally had my schedule figured out. With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It was actually much better than middle school and much more challenging. Since then, I've been elected（选举）vice monitor of my class, which wasn't much of a victory since only three people ran for the four positions.

    It is normal to be scared about a new school. Take a deep breath and relax. High school is something that any student can overcome. Make sure you participate in some out-of-class activities because you'll find it easier to make friends. Try to do your best  even if it isn't straight A's.

    Most important of all, be who you are, whether you're a "fool"， an athlete, or a lower grader. Don't try to pretend to be someone you're not. Now you know the true secrets of high school.

    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.
