One of my father's friends, Bernie, was a rich businessman, who owned a large store in St. Paul.Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie's place. We' d sit on the edge of the dock（码头）, feet dangling（摇晃）, and got ready for a big meal.Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we'd bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.Bernie was my father's idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie's wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don't take the time to dangle your feet over the dock and enjoy life's small pleasure, your work is probably hurting your life.For many years, I forgot that lesson I'dlearned as a kid on the loading dock. I was too busy making all the money I could.Well, I've relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That's the heart of the watermelon. I have learned again to throw the rest away.( ) 1. We learned from the second paragraph that the writer and his father were feeling ______.A. relaxedB. worriedC. hungryD. proud( ) 2. How did the writer and his father eat the watermelon?A. They ate it in a polite way.B. They only ate its best part.C. They ate every part of it.D. They shared only one piece.( ) 3. In the eyes of the writer's father, Bernie ______.A. was just a rich businessmanB. worked hard all the timeC. lived a rich but healthy lifeD. knew how to make money( ) 4. The underlined part “the heart of the watermelon” in th e last paragraph refers to ______.A. the best part of the watermelonB. the writer's busy lifeC. the writer's decision of making moneyD. the writer's hope of enjoying life( ) 5. It can be learned from the passage that ______.A. one has to work hard to reach his goalB. a friend in need is a friend in deedC. watermelon is the healthiest fruitD. one should keep work-life balanceBWhen the Audet family turns on the lights at Blue Farm, they are usingelectricity that comes from cows—cow manure (粪肥), to be specific.Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That's really a big amount.When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.Here's how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren't bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work andcontinue to digest the manure.Methane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That's an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can't use themselves.( ) 6.

There were not many people on earth, and natural resources seemed to be unlimited.Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers orinto the sea, and there are few laws to stop this.We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.What can we do to solve these problems?If we eat more vegetables and less meat, we will easily get more food.
