When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never yelled at us for playing in his yard, but was always very kind.

    When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle “No pain, no gain”. He hardly watered his new trees, which flew in the face of conventional(传统的) wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

    Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some twenty five years ago. They were all tall and strong.

    I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity(逆境) seemed to benefit Doctor Gibb's trees in ways comfort and ease never could.

    Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to meet with hardship. There's always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won't be torn apart.

    We do not know when man first began to use salt, but we do know that it has been used in many different ways throughout history. Historical evidence shows, for example, that people who lived over 3,000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve (保存) the dead.

    Stealing salt was considered a major crime (罪行) during some periods of history. In the eighteenth century, for example, if a person was caught stealing salt, he could be put in prison and his ears could be cut off.

    In the Roman Empire, one of the most important roads was the one that carried salt from the salt mines to Rome. Guards were stationed(安置) along the route to protect against salt thieves, and they received their pay in salt, thus bringing the English word, salary. Any guard who fell asleep while on duty was thought to be “not worth his salt”, and as a result he would get a little less salt on his next payday. The expression, “not worth his salt”, is still used today in English.

    In the modern world salt has many uses beyond the dining table. It is used in making glass and airplane parts, in the growing of crops, and in the killing of weeds (杂草). It is also used to make water soft, to melt (融化) ice on roads and highways, to make soap, and to fix colors in cloth.

    Salt can be got in various ways besides being taken from mines underground. Salt water from the ocean, salt water lakes or small seas can be used to make salt. Yet, no matter where it comes from, salt will continue to play an important role in the lives of people everywhere.

    Just 10 years ago, I sat across the desk from a doctor. “Yes,” he said, “there is something wrong with the left, upper lung. You are suffering a severe cancer. You'll have to give up work at once. Later on, we'll see.”

    Feeling like a man who is in mid­career has suddenly been placed under sentence of death, I left the doctor's office, walked over to the park, and sat down on a chair. I needed to think. In the next 3 days, I cleared up my affairs, then I went home, got into bed, and set my watch to tick off not the minutes, but the months. Two years later, I left my bed and began the long climb back. It was another year before I made it.

    I speak of this experience because these years that passed so slowly taught me what to value and what to believe. I realize now that each day, to me, is a precious thing. I've learned to appreciate those little things I never thought I had the time to notice before: the play of light on running water, the music of the wind.

    Frequently, I sit back and say to myself, “Let me make note of this moment I'm living right now, because in it I'm well, happy and hard at work doing what I like best to do. It won't always be like this, so while it is, I'll make the most of it—and afterwards, I remember—and be grateful. I contribute all these to that long time spent on the fight with cancer.”

    At first glance Esther Okade seems like a normal 10-year-old. She loves dressing up, playing with Barbie dolls and going to the park or shopping. But what makes the British-Nigerian youngster stand out is the fact that she's also a university undergraduate.

    Esther, from Walsall, an industrial town in the UK's West Midlands region, is one of the country's youngest college freshmen. The talented 10-year-old enrolled at the Open University, a UK-based distance learning college, in January and is already top of the class, having recently scored 100% in a recent exam.

    "It's so interesting. It has the type of maths I love. It's real maths-theories, complex numbers, all that type of stuff," she smiles. "I want to finish the course in two years. Then I'm going to do my PhD in financial maths when I'm 13. I want to have my own bank by the time I'm 15 because I like numbers and I like people and banking is a great way to help people." she adds.

    Esther has always jumped ahead of her peers. She sat her first Math GSCE exam, a British high school qualification, at Ounsdale High School in Wolverhampton at just six, where she received a C-grade. A year later, she got the A-grade she wanted. Then last year she scored a B-grade when she sat the Math A-level exam.

    Not content with breaking barriers to attend college at just 10 years old, Esther is also writing a series of math workbooks for children called "Yummy Yummy Algebra."

    "It starts at a beginner level-that's volume one. But then there will be volume two, and volume three, and then volume four. As long as you can add or subtract, you'll be able to do it. I want to show other children they are special." she says.

    One of the most famous buildings in the United States is Carnegie Hall, the home of classical and popular music concerts in New York. Carnegie Hall is known not just for its beauty and history, but also for its amazing sound. It has been said that the hall itself is an instrument. It takes the music and makes it larger than life.

    Carnegie Hall is named after Andrew Carnegie, who paid for its construction. Construction on Carnegie Hall began in 1890 and the official opening night was on May 5, 1891.

    The hall was owned by the Carnegie family until 1924 when it was sold to Robert E. Simon. The building became very old and in 1960, the new owner made plans to destroy it and build an office block. Isaac Stem led a group of people who fought to save Carnegie Hall and finally, the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.

    Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall's concert history.

Carnegie Hall is actually made up of several different halls, but the Main Hall, now called the Isaac Stern Hall, is the most famous. The hall itself can hold an audience of 2,804 in five levels of seating.

    Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall's history. Question: "How do I get to Carnegie Hall?" Answer: "Practise, practise, practise."
