To develop one's taste in English，the most effective way is to read English books extensively. However, one may be at a loss to choose the appropriate books，especially as a beginner.I would like to share some of my experience.

    My first English novel was Jane Austen's Pride and Prejudice，recommended by many English teachers and professors as an ideal book for English learners. But I had great difficulty in understanding the novel，let alone enjoying it. It's not the vocabulary that troubled me，but rather the way Austen constructs sentences，and her way of thinking，which seemed too remote to me at that time. My fading enthusiasm was much recovered after reading Hemingway's novel Farewell to Arms. I particularly liked his brief and lively style. So my first suggestion is，as a beginner, you'd better choose contemporary novels instead of classical ones.

    However，reading novels is not the only way to improve your English. English essays can at once inform you，entertain you, and improve your taste in English. The best example is Bertrand Russell's work. Its language is plain, yet you cannot help feeling the elegance and the unique sense of humor. His simple language enables his philosophy(哲理) within the reach of ordinary people. Here comes my second suggestion—essays are indispensable.

    Never follow other's opinions blindly，however famous or influential the person might be. As a saying goes，one man's meat is another man's poison. With that in mind，we are sure to find out our favorite writers through reading and develop our fine taste in English.

    Technology is the application of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has made our life span longer via medical technology.

    Will mankind continue to live longer and have a higher quality of life? In large measure, the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends on research and development, and the latest surveys show that the united States is continuing to put billions of dollars annually(每年) into such efforts. So while we are running out of some limited resources, we may well find technological substitutes (代用品) for many of them through our research programs.

    Therefore, in the final analysis, the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills or techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us improve our standard of living.

    In the fall of 1985, I was a bright-eyed girl heading off to Howard University to study law, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.

    My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.

    Then I got married with another dream: building my family with a combination of adopt and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic and very emotional. A year later came our second adopted boy. Then followed son No.3. In 2003, I gave birth to another boy.

    You can imagine how busy I became, raising four boys under the age of 8. Our home was a complete zoo--a joyous zoo. Not surprisingly, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.

    The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.

    In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!

    I am not special, just single-minded. It always struck me that when you're looking at a big challenge from the outside it looks huge, but when you're in the midst of it, it just seems normal. Everything you want won't arrive in your life on one day. It's a process. Remember: little steps add up to big dreams.

    It was close to midnight and it was unusual to see vehicles on the road. However, several trucks pulled over and workers silently unloaded camera equipment and cardboard boxes, and then carried them inside the Morgenson family home.

    What took place over the next eight weeks was inspired by a Hollywood movie called The Joneses about a family of marketers who move into a local neighborhood to sell their products secretly to their neighbors. The idea was to test the power of word-of-mouth marketing. By filming a 'rear' family in unscripted (无剧本的) situations, my team and I would document how the Morgensons' circle of friends responded to brands and products the Morgensons bought into their lives.

    With the help of 35 video cameras and 25 microphones hidden inside the furniture, the operation done secretly showed something shocking. The most powerful hidden persuader of all isn't in your TV or on the shelves of your supermarket. It's a far more important influence that's around you almost every waking moment: your very own friends and neighbors. There is nothing quite so persuasive as observing someone we respect or admire using a brand or product.

    Our analysis also found that the brands the Morgensons used went faster. About one third of the Morgensons' friends began promoting these same brands to their friends. We also found that the brands their friends were most likely to buy at the Morgensons' suggestion were the bigger and better-known ones. This proved my thoughts that traditional marketing and secret marketing work well together. The most persuasive advertising strategies are strengthened by word-of-mouth advertising.

    Whenever I meet with company managers, I tell them that the people who hold the real marketing power are mouse-clicking consumers and their wide circles of real-life friends. In other words, the people who hold the real power are us.

    On plenty of drives with my mom through my childhood, she would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle from tragedy while I, in my late teens and early twenties, sat impatiently in the car.

    Though Mother's Day follows Earth Day, for me, they have always been related to each other. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, mom saves glass jars, empty cheese containers and reuses her plastic bags.

    Mom creates a kind of harmonious relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to avoid the bears and that if she leaves the bird feeders out at night, it is likely that they will be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house and are caught in juice glasses will be set loose in the garden.

    I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for dandelions(蒲公英) to fly in the wind; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn't need to lecture; she didn't need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came mercy and an instinct(直觉) for protection.

    I am slowing down and it isn't because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I've begun to save glass jars and reuse packing envelopes. I pause in my daily tasks to watch the squirrels race each other in the trees above my house.

    Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with sweetness. I immediately wanted to share with my mom.

    You may think that light pollution isn't something extraordinarily important. You may believe that every other type of pollution has a larger impact on the environment than light pollution does. But light pollution is serious.

    Light pollution, or "sky glow", is the glow you can see at night above cities and towns. Light pollution is a problem that has been accompanying man ever since he started his first fire some 15,000 years ago. Light pollution is the light that comes from streetlights, buildings, parking lots and any other source of light that is reflected or directed into the atmosphere.

    Urban light pollution means that one­fifth of the world's population can no longer see the Milky Way with the naked eye(肉眼). Many city kids, even if they did look through the orange smog above their heads, would probably see only a handful of stars. We have lost our view of the stars, and we have mucked up our night­time environment as well. Astronomers are calling for the dark places on Earth to be preserved as national parks.

    Lots of people find the ever­brightening night annoying, and animals that are programmed to prefer the dark may avoid a brightened habitat. Sea turtles can get lost searching for a beach to lay eggs, and their hatchlings(孵化的幼仔)may confuse over­lit beachfront resorts for the ocean horizon, wasting precious energy needed to find the sea and escape predators(食肉动物). Because their necks aren't yet long enough to see things far away, baby turtles rely on the mirror image of the moon to guide them to the sea, to begin their new life. A car may even hit a particular turtle, which was thinking the light from a nearby city was moonlight reflecting off the ocean waves. Birds that live in and around cities can die because of sky glow, too. The bright lights can blind them, leading to countless collisions with buildings and other tall structures.

    On an individual level, people can help reduce much sky glow by using lighting only when necessary. The stars above us are priceless heritage— for not only for astronomers but for all humans. More of our children should be able to look up at night and see the Milk Way.
