What is success? I am not going to try to explain success. I think a precise meaning is impossible! Is it winning a Gold Medal at the Olympic Games or winning Wimbledon, or being awarded a Nobel Prize? What else? I believe personal success could be anything at all- it does not have to involve public recognition. Who is more successful? A millionaire who is unhappy, or an unnoticed person, who has led a simple, quiet, sincere and happy life? The simplest definition of success, I think, is “to set out to do something and to succeed in doing it.

    The first step on the road to success starts with belief. Believe you can succeed and you will. Achieving success in whatever endeavor(努力)you choose may be the goal of life; because it gives you freedom from worry. Could that be?

    Success means different things to every one of us. Some people believe it is measured in financial term; others believe it is helping others rather than helping themselves. However, most people are motivated to a great extend by public recognition. How many people are really happy? How many people are really doing what they want to with their lives? Incidentally, to imagine makes us different from animals.

    Most important of all, I believe success is a matter of personal growth. If every day you are developing or growing just a millimeter, I believe one is successful. Just being a slightly better person each day for me is success. I've got a very long way to go them!

    Finally, always remember success is a process and is not simply a matter of arriving at a destination. It's the journey that really matters. Success is what you become in the often very difficult and dangerous journey down the river of life.

    For most caffeine(咖啡因)consumers, its main benefit is that it helps you get more done. This is what makes it unusual, says Stephen Braun, author of Buzz: The Science and Lore of Alcohol and Caffeine.

    “Its appeal is that it helps us earn more money,” he adds. “What makes it different from other drugs is that it's used as a productivity tool –– not for pleasure.”

    Many of history's creative minds have also been connected with a large amount of caffeine consumption (消耗).

    According to one biographer, the French novelist and playwright Balzac drank as many as 50 cups of coffee a day. “Were it not for coffee one could not write, which is to say one could not live,” he once insisted.

    For seven years, the film-maker David Lynch ate at the same Los Angeles diner every day, drinking up to seven sweetened cups of coffee “with lots of sugar” in one sitting, which he said would guarantee that “lots of ideas” arrived.

    Ludwig van Beethoven was said to have painstakingly counted out exactly 60 coffee beans per cup when he brewed(煮)coffee.

    Perhaps recent tales of caffeine excess (过量) featured the singer Robbie Williams, who reportedly consumed 36 cups of black coffee and 20 cans of Red Bull a day.

    It is the routine task itself, as much as the stimulating(刺激的)effects of caffeine, that makes the process so important, says Mason Currey, author of Daily Rituals: How Artists Work. “A lot of artists use the process of making coffee as a gateway to the creative process,” he adds. “You need to get into the right mindset to do that sort of work, and the preparation process provides a focus.”

    One problem with attempting to control caffeine, says Braun, is that it affects everyone differently –– it is impossible to work out a “safe” limit that works for everyone. “Eventually, you have to become your own scientist –– there isn't an alternative to careful self-experimentation,” he says.

    People all need friends because nobody wants to be lonely and a friend can help you in good and bad times. You've made friends since childhood, but you still don't know who your true friends are. Here are some signs to tell you if your friend is a true friend:

Always honest

    Honesty is important to keep a relationship alive. A true friend always tells you the truth. It may be hard sometimes but lying can destroy a friendship. It is important that your friend speaks honestly and never makes up stories.

______________

    There are always periods in your life when you have problems or difficulties. A true friend will always have time to listen to your problems and give advice. It may not be able to offer a solution to your problems but the fact that your friend made time to listen is a sign he/she cares for you. Your friend is not a true friend if he/she can never make time for you when you are in trouble. You also need to be reasonable and accept that your friend also has other things to do so he/she can't always listen immediately to your problems.

Always respectful

    A true friend will always respect your opinion no matter whether he/she agrees or not. Your true friend may disagree but never insists that he/she is correct.

Always understanding

    It is possible that some problems will arise between you and your friend. A true friend will always be forgiving and understanding even if it isn't his /her fault. We are all different people and we all make mistakes. A true friend is always forgiving and understanding because he/she doesn't want to take the risk of losing his/her best friend.

    My motivation for starting our family tradition of reading in the car was purely selfish: I could not bear listening to A Sesame Street Christmas for another 10 hours. My three children had been addicted to this cassette on our previous summer's road trip.

    As I began to prepare for our next 500-mile car trip, I came across a book Jim Trelease's The Read Aloud Handbook. This could be the answer to my problem. I thought. So I put Roald dahl's James and the Giant Peach into my bag. When I began to read aloud the tale of the boy who escapes the bad guys by hiding inside a giant peach, my three kids argued and wrestled in their seats. But after several lines, they were attracted into the rhythm of the words and began to listen.

    We soon learned that the simple pleasure of listening to a well-written book makes the long miles pass more quickly. Sometimes the books we read became highlights of the trip. I read Wilson Rawls's Summer of the Monkeys as we spent two days driving to the beach. We arrived just behind the power crews restoring (恢复) electricity after a tropical storm. The rain continued most of the week, and the beach was covered with oil washed up by the storm. When we returned home, I asked my son what he liked about the trip. He answered without hesitation, “The book you read in the car.”

    Road trips still offer challenges, even though my children now are teenagers. But we continue to read as we roll across the country. And I'm beginning to see that reading aloud has done more than help pass the time. For at least a little while, we are not shut in our own electronic worlds. And maybe we've started something that will pass on to the next generation.

    Over the past century, an alarming number of animals have become endangered or even extinct. Below are some animals whose numbers have been rapidly dropping in recent years.

    Panda Bear

    One of the biggest reasons contributing to the decline in the panda species is the destruction of its natural habitat. Farmers in China have gradually been claiming more and more of the land. As a result, pandas are forced to move away to places where it is hard to find bamboo for food.

    Green Turtle

    The green sea turtle species has survived for several millions of years, so you might wonder why it's only becoming endangered now. A major cause is the change in climate and temperature, which both affect the hatching rates of turtle eggs. Climate changes also cause violent weather and rising water levels to flood areas where turtles usually go to lay their eggs. Apart from this, oil spills and other poisonous pollution, as well as increased fishing activities can cause sickness, or even death to the green turtles.

    Cheetah

    Cheetahs are famous for being the fastest animal on land but even they can't run from some of the larger threats that have harmed them. Like the panda bears, cheetahs have gradually been losing their natural homes due to humans claiming land and developing in those areas. To make matters even worse, smaller animals move away when these areas are occupied, which means that the cheetah has less food! Don't forget that other large animals, such as lions, are also fighting for any food that they can find, so occasionally young cheetahs end up as prey too.

    Indian Elephant

    Elephants are extremely intelligent animals and also the largest mammals that live on land. Sadly, in Asia many elephants were killed so that people could remove their tusks to use as decorative objects. While this practice has been banned now, some people still illegally continue. Forests in India have also been steadily destroyed and elephants are sometimes killed when they end up on human territory.

    Mary Anning was an English fossil collector, dealer and paleontologist(古生物学家). Her fossil-hunting helped change the way people thought about the world.

    Mary was born into a poor family in England on May 21, 1799. She lived in the seaside town of Lyme Regis, in Dorset. The family had nine children. Only Mary and her brother Joseph grew up. Mary's father took his children along the beach. They picked up shells and stones to sell to visitors. Mary did not go to school much. Her family was too poor. And schools did not teach children about fossils. Mary could read and write. She taught herself. She learned about rocks and how bodies are made.

    In 1811 when Mary and Joseph were fossil hunting, Joseph saw a bone sticking out of the rock. Mary had a hammer to chip away at the rock. Very carefully she uncovered it. She found the first complete fossil of the ichthyosaur(鱼龙).

    Since then, Mary became crazy about fossil hunting. She liked to hunt on the beach after a storm. The wind, rain and waves made the rocks crumble. It was easy to spot fossils. Most days Mary went fossil hunting with her dog, Tray.

Rich friends helped Mary by selling fossils for her. They sent her money. Scientists wrote letters and came to see her. One good friend was William Buckland, a professor at Oxford University. Mary also opened a shop to sell fossils, stones and shells. She chatted with visitors.

    Mary Anning died in 1847. How evolution(进化)works was explained by Charles Darwin not long after Mary died. Her fossils had helped scientists understand how things began.
