    Some years ago, Danny gave up his job as a doctor to become a freelance(特约的) model maker, but now he has money trouble. He says that he wishes he'd never 1 to set up his own business.

    "I am now in such a bad situation," says Danny. "I hope I'm 2 working as a doctor. You see, I was 3 with my job, and I didn't have any fun. I said to a few friends that I wanted to go into 4 and they said that they could give me work, so I left the hospital.

    At first, everything was 5: I had too much work to do. I got too many orders every day. And soon I 6a large number of money. I had a really great lifestyle, and when the work was finished, I used to take good 7 in places like the beautiful blue Aegean Sea, Maldives, Hawaii and so on, just to get relaxed.

    Like this, I was busy having fun all around the world, and charged (支付) everything to my credit (信用) cards, but then I began to 8 how much in debt (负债) I was. At last, I had to sell all my office equipment (设备). Now I could do almost 9 even if people asked me. I've had to 10 my business now and I don't know what I'm going to do for money.

Many studies about language learning ask the question: What makes a good language learner? Here is some of the most {#blank#}1{#/blank#} (use) advice from studies.

*Don't be afraid- of making mistakes. People often get things wrong. Good language learners don't worry about making mistakes. {#blank#}2{#/blank#},they learn from them.

* Do group activities. People use the language {#blank#}3{#/blank#} (communicate) with others. A good language learner always {#blank#}4{#/blank#} (look) for opportunities to talk with others.

* {#blank#}5{#/blank#}(take) notes every day.Write down just five to ten new words and phrases each day. Review {#blank#}6{#/blank#} (they) from time to time.

* Practice {#blank#}7{#/blank#} (speak) daily. Speak to real people, if possible. 'They can be your teachers or friends. But if you have nobody to speak to, you can watch films and repeat what the actors say.

* Spend some time {#blank#}8{#/blank#} (think) in the language you learn. A good first step is to think in words.Try to name each object around you.Then think in simple sentences. {#blank#}9{#/blank#}example, if you are sitting in a park, you can say, "It's such a beautiful day." Then you can move to think in conversations.Imagine yourself {#blank#}10{#/blank#} (talk) to someone else. You are asking the questions and thinking of replies(回答). The secret to developing a habit of thinking in the language is doing it every day, over and over again.
