Years ago, when I started looking for my first job, wise advisers urged, "Barbara, be enthusiastic! Enthusiasm will take you further than any amount of experience."

    How right they were. Enthusiastic people can turn a boring drive into an adventure, extra work into opportunity and strangers into friends.

    ''Nothing great was ever achieved without enthusiasm, wrote Ralph Waldo Emerson. It is the paste that helps you hang in there when the going gets tough. It is the inner voice that whispers, I can do it! " when others shout, "No, you can't."

    It took years and years for the early work of Barbara McClintock, a geneticist（遗传学家） who won the 1983 Nobel Prize in medicine, to be generally accepted． Yet she didn't let up on her experiments. Work was such a deep pleasure for her that she never thought of stopping.

    Author and poet Samuel Ullman once wrote, "Years wrinkle the skin, but to give up enthusiasm wrinkles the soul".

    Enthusiastic people also love what they do, regardless of money or title or power. If we cannot do what we love as a full-time career, we can treat it as a part-time interest, like the head of state who paints, the nun(修女) who runs marathons, the official who handcrafts（手工制作）furniture.

    We can't afford to waste tears on "might- have-beens". We need to turn the tears into sweat as we go after ''what-can-be".

    We need to live each moment wholeheartedly, with all our senses—finding pleasure in the fragrance of a back-yard garden, the crayoned（蜡笔的）picture of a six-year-old, the enchanting beauty of a rainbow. It is such enthusiastic love of life that puts a sparkle in our eyes, a lilt in our steps and smooths the wrinkles from our souls.

    Why do so many Americans distrust what they read in their newspapers? The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.

    Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.

    But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard patterns into which they report each day's events. In other words, there is a traditional story line in the newsroom culture that provides a backbone and a ready-made narrative structure for otherwise confusing news.

    There exists a social and cultural disconnect between journalists and their readers, which helps explain why the "standard patterns" of the newsroom seem foreign to many readers. In a recent survey, questionnaires were sent to reporters in five middle-size cities around the country, plus one large metropolitan area. Then residents in these communities were phoned at random and asked the same questions.

    Replies show that compared with other Americans, journalists are more likely to live in upscale neighborhoods, have maids, own Mercedeses, and trade stocks, and they're less likely to go to church, do volunteer work, or put down roots in a community.

    Reporters tend to be part of a broadly defined social and cultural elite (精英), so their work tends to reflect the traditional values of this elite. The alarming distrust of the news media isn't rooted in inaccuracy or poor reportorial skills but in the daily conflict of world views between reporters and their readers.

    This is an explosive situation for any industry, particularly a declining one. Here is a troubled business that keeps hiring employees whose attitudes vastly annoy the customers. Then it sponsors lots of symposiums (讨论会) and a credibility project devoted to wondering why customers are annoyed and fleeing in large numbers. But it never seems to get around to noticing the cultural and class prejudices that so many former buyers are complaining about. If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.

    Knowing a little first aid could be life-saving if you see someone lying unconscious.

    Too often people don't do anything because they think they will kill the patient, but by learning simple rules you could make the difference between life and death.

    First, you need to find out if they're unconscious, asleep or drunk, by squeezing the skin between their neck and shoulder and shouting. If there is no response at all, you need to establish if they are dead or just unconscious—sometimes it's very difficult to tell the difference.

    Open the airway by placing one hand on their forehead and gently tilting the head back while lifting the chin.

    If there are no signs of life—no obvious pulse and their chest is not going up and down—call an ambulance and then start cardiopulmonary resuscitation (CPR) (心脏复苏) to maintain (获得) a flow of oxygenated blood to the brain and heart.

    Do this by pushing up and down on the centre of the chest, with your hands interlocked together, constantly until an ambulance arrives.

    Push at a rate of 100 beats a minute. You can't harm them doing this and might just save a life.

    My sister Alice and I have been trying to get people to stop dropping cigarette (香烟)butts(烟头)for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people dropping butts. We called it "No Butts About It".

    At first, we drew pictures with "The Earth is not your ashtray(烟灰缸)"written on them. We put the pictures around our hometown—in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don't think that dropping butts hurts the Earth. But it does, and all rubbish does!

    Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn't have to drop butts.

    At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other "No Butts About It" groups in America.

    Now there even groups in England, Australia, and India! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we do. But we are not interested in prizes. We just want to make the Earth a better and cleaner place for animals, plants and people.

    One day, it will be.

    Picture this: You're searching the Internet and come across a website with interesting articles. Some are news stories. Their goal is to share information. Others only look like news stories. They're actually advertisements, or ads. The goal of an ad is to get you to buy something. How do you, the reader, tell the difference between a news story and an ad?

    Back when I was growing up, it was easier. We got most of our information from newspapers. Big news stories appeared on the front page, and ads were boxed off and clearly labeled. But on the Internet, the two are often presented together. It can be hard to tell which is which.

    That's why the research group I direct conducted a study. My research team showed kids like you the home page of a popular digital magazine. We asked them to tell us what was a news story and what was an ad.

    Most were great at identifying certain types of ads. "It has a coupon (优惠券) code, a big company logo, and the words 'limited time offer'," one student wrote about an ad on the site. So where did kids get stumped (难倒)？

    Some ads seem identical to real news stories. They have headlines and contain information. But they may also include the words "sponsored content". Sponsored means "paid for," and content refers to the information in the story. "Sponsored content" is a way of saying that something is an ad. Most kids in our study, even if they used the Internet often, didn't know this.

    Something sponsored doesn't necessarily mean it's false. It means someone paid money for it to appear. Companies pay so that readers will see their stories, buy their products, and like what the company stands for.

    As a reader, you have a right to know who's behind the information you're consuming. So, look for the phrase sponsored content. (And look carefully. Sometimes, it will be written in tiny letters.) The Internet is a vast sea of information. To use it well, we not only have to know how to swim but also how to avoid the sharks.

The Big Ben is located in the tower at the eastern end of the Houses of Parliament, Westminster, Greater London. It was designed by Edmund Beckett and Baron Grimthorpe.

The Big Ben is very famous throughout the world, but nobody really knows why it is called Big Ben. There are two hearsays about this. Some people say that it was named after Benjamin Caunt, a boxer, who was called Big Ben. More people believe it was called after Welshman, Sir Benjamin Hall. He was the commissioner(特派员)of the work at the time of its installation in 1859. A story was told that during a debate in the Commons on what to call the bell, Sir Benjamin was about to give his ideas when a MP who sat behind the front bench shouted, "Let's call it Big Ben!" Then this name came into being.

The bell hasn't gone through a smooth road since the beginning of its design. Because there was great disagreement about the design of the clock. It took fifteen years to build. In 1857, the bell was completed and tested on the ground, but a four-foot crack appeared and the bell had to be cast again. Finally, the clock started ticking on 31 May, 1859, and struck its first chime(报时)on 11, July. Then in September, the bell cracked again. It was silent for four years but was eventually turned a quarter of a revolution(旋转). In this way, the crack was not under the striking hammer. Craftsmen made a square above the crack to stop it growing longer and it can still be seen today.

The Big Ben is famous not only for its 13-ton weight, but also for its accuracy(准确性) which is a result of its precise mechanism(机械装置). Even one extra penny's weight on the balance will cause a gain of two fifths of a second in twenty-four hours. Although there have been several problems, the bell is still striking today. Its chimes can be heard all over the world on the B. B. C.
