He had no money. But he needed a lot of money to buy the land, the house and the machines for his dream ranch.4 When Monty Roberts asked his father for advice, his father just asked him to make up his own mind on his dream because it is a very important decision for him to make.5 When Monty Roberts turned in the same paper, he said to his teacher, “You can keep the F and I’ll keep my dream . I will follow my heart , no matter what happens.”Read and ExploreTask One Discovering the Main Ideas1 Answer the following questions with the information contained in Text A.1) According to Alex Haley, why does many a young man want to be a writer? Because they think that being a writer can bring them wealth and fame.2) Does writing mean glory and wealth in the author’s opinion?No. The author thinks that writing is a lonely, private and poor-paying affair. Only a few can succeed after long periods of neglect and poverty.3) What was the author’s life in Greenwich Village like?His life in Greenwich Village was very poor. He barely made enough to eat.4) Did he ever doubt his ability to write? Why or why not?Yes. Because he didn’t receive a break after writing for a year or so.5) Why did the call from his old acquaintance change his life?Because his doubt of his resolution to write was cleared. He was determined to keep on writing.6) In what way did people like Delaney and Belafonte become role models for the author?From them he learned that one had to make sacrifices and live creatively to keep working hard to realize one’s dreams.7) How many years did the author keep on writing before his great success? He kept on writing for 17 years before his great success.8) What did the two sardine cans and 18 cents in the brown paper bag symbolize?They symbolized his courage and persistence to stick to his dream of writing.9) What is the meaning of the Shadowland of dreams?The Shadowland of dreams means all the difficulties (e.g. neglect, poverty, doubt, uncertainty, and fear of failure) people meet with in pursuing their dreams.2 Text A can be divided into three parts with the paragraph number(s) of each part provided as follows. Write down the main idea of each part.Part: One; Paragraph(s): 1-2; Main Idea: Alex Haley explains the difference between “being a writer” and “writing”.Part: Two; Paragraph(s): 3–18; Main Idea: The author tells about his struggle to stick to his dream of writing and his final success.Part: Three; Paragraph(s): 19-22; Main Idea: The author tells about his struggle to stick to his dream of writing and his final success.Task Two Reading Between the LinesRead the following sentences carefully and discuss in pairs what the author intends to say by the italicized parts.1) For every writer kissed by fortune, there are thousands more whose longing is never rewarded. (Para. 2)Compared with those lucky writers who have become famous, thousands of people who devote themselves to writing are never given recognition as successful writers.2) Next time I make a sale. (Para. 6)Considering the rather difficult circumstances the author was in, it is easy to see that there was a degree of irony and self-sarcasm when he promised his friend that he would pay back the money next time he made a sale, for it was something that had not happened before and would not be very likely to happen in the near future, thus pushing the repayment of the debt into the remote future.3) What’s more, I could write on the side. (Para. 8)More importantly, I could take writing as a part-time job.4) There’s everything you’ve made of yourself so far. (Para. 10)The two cans of sardines and 18 cents are all you have.5) Another Village neighbor was a handsome young singer who ran a struggling restaurant. (Para. 13)… a restaurant that has few customers and is about to close down.6) As I absorbed the lesson, I gradually began to sell my articles. (Para. 15) As I beca me aware of what it meant to live in the Shadowland, …7) For the first time I had money and open doors everywhere.

Unit3Book2Text AIt is perhaps human nature to be drawn towards fame and wealth.Yet,as Alex Haley points out through his own experience,in order to become successful,one must learn to struggle in the Shadowland of dreams—a deep forest that can swallow up those who swing and hesitate.Only the determined stand a chance of making it.The Shadowland of DreamsAlex Haley1Many a young person tells me he wants to be a writer.I always encourage such people,but I also explain that there’s a difference between“being a writer”and writing.In most cases these individuals are dreaming of wealth and fame,not the long hours alone at the type-writer.“You’ve got to want to write,”I say to them,“not want to be a writer.”2The reality is that writing is a lonely,private and poor-paying affair.For every writer kissed by fortune,there are thousands more whose longing is never rewarded.Even those who succeed often know long periods of neglect and poverty.I did.3When I left a20-year career in the Coast Guard to become a freelance writer,I had no prospects at all.What I did have was a friend with whom I’d grown up in Henning,Tennessee. George found me my home—a cleaned-out storage room in the Greenwich Village apartment building where he worked as superintendent.It didn’t even matter that it was cold and had no bathroom.Immediately I bought a used manual typewriter and felt like a genuine writer.4After a year or so,however,I still hadn’t received a break and began to doubt myself.It was so hard to sell a story that I barely made enough to eat.But I knew I wanted to write.I had dreamed about it for years.I wasn’t going to be one of those people who die wondering,“What if?”I would keep putting my dream to the test—even though it meant living with uncertainty and fear of failure.This is the Shadowland of hope,and anyone with a dream must learn to live there.5Then one day I got a call that changed my life.It wasn’t an agent or editor offering a big contract.It was the opposite,a kind of siren call tempting me to give up my dream.On the phone was an old acquaintance from the Coast Guard,now stationed in San Francisco.He had once lent me a few bucks and liked to egg me about it.“When am I going to get the$15,Alex?”he teased.6“Next time I make a sale.”7“I have a better idea,”he said.“We need a new public-information assistant out here,and we’re paying$6,000a year.If you want it,you can have it.”8Six thousand a year!That was real money in1960.I could get a nice apartment,a used car, pay off debts and maybe save a little something.What’s more,I could write on the side.9As the dollars were dancing in my head,something cleared my senses.From deep inside a bull-headed resolution welled up.I had dreamed of being a writer—full time.And that’s what I was going to be.“Thanks,but no,”I heard myself saying.“I’m going to stick it out and write.”10Afterward,as I paced around my little room,I started to feel like a fool.Reaching into my cupboard—an orange crate nailed to the wall—I pulled out all that was there:two cans of sardines.Plunging my hands in my pockets,I came up with18cents.I took the cans and coins and jammed them into a crumpled paper bag.There Alex,I said to myself.There’s everything you’ve made of yourself so fa r.I’m not sure I ever felt so low.11I wish I could say things started getting better right away.But they didn’t.Thank goodness I had George to help me over the rough spots.12Through him I met other struggling artists,like Joe Delaney,a veteran painter from Knoxville,Tennessee.Often Joe lacked food money,so he’d visit a neighborhood butcher who would give him big bones with small pieces of meat,and a grocer who would hand him some withered vegetables.That’s all Joe needed to make his favorite soup.13Another Village neighbor was a handsome young singer who ran a struggling restaurant. Rumor had it that if a customer ordered steak,the singer would dash to a supermarket across the street to buy one.His name was Harry Belafonte.14People like Delaney and Belafonte became role models for me.I learned that you had to make sacrifices and live creatively to keep working at your dreams.That’s what living in the Shadowland is all about.15As I absorbed the lesson,I gradually began to sell my articles.I was writing about what many people were talking about then:civil rights,black Americans and Africa.Soon,like birdsflying south,my thoughts were drawn back to my childhood.In the silence of my room,I heard the voices of Grandma,Cousin Georgia,Aunt Plus,Aunt Liz and Aunt Till as they told stories about our family and slavery.16These were stories that black Americans had tended to avoid before,and so I mostly kept them to myself.But one day at lunch with editors of Reader’s Digest,I told these stories of my grandmother and aunts and cousins.I said that I had a dream to trace my family’s history to the first African brought to these shores in chains.I left that lunch with a contract that would help support my research and writing for nine years.17It was a long,slow climb out of the shadows.Yet in1970,17years after I left the Coast Guard,Roots was published.Instantly I had the kind of fame and success that few writers ever experienced.The shadows had turned into dazzling limelight.18For the first time I had money and open doors everywhere.The phone rang all the time with new friends and new deals.I packed up and moved to Los Angeles,where I could help in the making of the Roots TV mini-series.It was a confusing,exciting time,and in a sense,I was blinded by the light of my success.19Then one day,while unpacking,I came across a box filled with things I had owned years before in the Village.Inside was a brown paper bag.20I opened it,and there were two corroded sardine cans,a nickel,a dime and three pennies. Suddenly the past came flooding in like a tide.I could picture myself once again huddled over the typewriter in that cold,bleak,one-room apartment.And I said to myself,The things in this bag are part of my roots,too.I can’t ever forget that.21I sent them out to be framed.I keep that clear plastic case where I can see it every day.I can see it now above my office desk in Knoxville,along with the Pulitzer Prize,a portrait of nine Emmys awarded to the TV production of Roots,and the Spingarn medal—the NAACP’s highest honor.I’d be hard pressed to say which means the most to me.But only one reminds me of the courage and persistence it takes to stay the course in the Shadowland.22It’s a lesson anyone with a dream should learn.▇课文重点词汇Good Usage(Paras.1-2)Many a young personIn most casesdreaming of wealth and famekissed by fortunenever rewardedlong periods of neglect and povertyGood Usage(Para.3)had no prospects at allworked as superintendentIt didn’t even matter thatGood Usage(Paras.4-5)hadn’t received a breakbegan to doubt myselfbarely made enough to eatputting my dream to the testliving with uncertainty and fear of failureoffering a big contracta kind of siren call tempting me to give up my dreamegg me about itGood Usage(Paras.6-9)make a salepay off debtson the sidethe dollars were dancing in my headsomething cleared my sensesa bull-headed resolution welled upstick it outGood Usage(Para.10)paced around my little roomPlunging my hands in my pocketscame up withThere’s everything you’ve made of yourself so farfelt so lowGood Usage(Paras.11-12)Thank goodnesshelp me over the rough spotsGood Usage(Paras.13-14)Rumor had it thatbecame role models for memake sacrificesGood Usage(Paras.15-16)absorbed the lessonmy thoughts were drawn back to my childhoodtended to avoidmostly kept them to myselftrace my family’s history toGood Usage(Paras.17-18)a long,slow climb out of the shadowsThe shadows had turned into dazzling limelight.I had money and open doors everywherepacked upin a senseblinded by the light of my successGood Usage(Paras.19-20)came acrossSuddenly the past came flooding in like a tide.huddled overGood Usage(Paras.21-22)be hard pressed to sayreminds me of the courage and persistencestay the course in the Shadowlanda lesson anyone with a dream should learnKey Words and Expressions for Text Amany afml many〖正式〗a large number of许多e.g.1.Many a scientist has to work long hours alone in the laboratory and sacrifice a great dealin his or her personal life.2.I’ve sat here many a time and wondered what happened to her.我很多次坐在这里想：她发生了什么事？Usage:注意many a后接名词单数，谓语动词也需要保持一致。
