One evening I was resting in a cafe.I wore a pair of newly bought white leather shoes,  {#blank#}1{#/blank#}  were rather expensive.Then a boy came to me.

     He was in {#blank#}2{#/blank#} old and not fit shirt, looking pale and about eleven.No sooner had I begun to speak than he opened the box in his hand and took out the tools of shoe­polishing.He was busy doing his work{#blank#}3{#/blank#}  heavy rain began to pour down.People rushed to the cafe for {#blank#}4{#/blank#}  (protect) from the rain.More and more people crowded in and gradually separated the boy {#blank#}5{#/blank#}  me.

     Hours passed，and it turned dark.I had no shoes on my feet and wondered where the boy had been.I thought I would have to go home on my bare feet. When it was near midnight, the cafe was to be closed.I had to move to the door，just as I went to the gate，I {#blank#}6{#/blank#} (surprise) found that a boy of about eleven, {#blank#}7{#/blank#}  (look) very familiar，was sleeping at the door with his head leaning  {#blank#}8{#/blank#}  a box.I shook him slightly and woke him{#blank#}9{#/blank#}  .He opened the package hurriedly, gave me my leather shoes, and apologized to me shyly.I paid him and wrapped him with his {#blank#}10{#/blank#}  (fit) shirt.On my way home, the image of the boy stayed in my mind.

    On a{#blank#}1{#/blank#}(freeze) cold day,Mrs Smith's dog was hungry,but there was not any meat{#blank#}2{#/blank#}(leave) in the house.

    {#blank#}3{#/blank#} (consider) there was no better way,Mrs Smith took a piece of paper,and wrote the{#blank#}4{#/blank#}(follow) words: “Give my dog half a pound of meat.”Then she asked her dog to take it to the butcher's.When the butcher recognized that it was really the lady's handwriting,he did as he{#blank#}5{#/blank#}(ask) to.The dog was very happy,and ate the meat up immediately.

    The next day,the dog came again exactly at midday.And as{#blank#}6{#/blank#}(usually),it brought a piece of paper in the mouth.This time the butcher did not take a look at the paper,and just gave the dog its meat,for he had regarded the dog{#blank#}7{#/blank#}one of his customers.

    One day later,to the butcher's more surprise,it came at six o'clock and brought{#blank#}8{#/blank#}third piece of paper.Though {#blank#}9{#/blank#}(surprise),the butcher gave him{#blank#}10{#/blank#}he wanted.But what he didn't know was,that there were not any words on the paper!

    A few people have lucid (清醒的) dreams, in {#blank#}1{#/blank#} the dreamer is aware they're dreaming and can control the experience. Some others can learn {#blank#}2{#/blank#} (have) lucid dreams. The practice can be used to deal with frightening dreams. However, its potential has been limited by it often {#blank#}3{#/blank#} (be) so hard to achieve. Now, researchers have developed the most effective method yet for promoting lucid dreams.

    The researchers let 121 adults aged 19 to 75 pick something {#blank#}4{#/blank#} (see)in a previous dream. It was called a "dreamsign" that can serve {#blank#}5{#/blank#} a reminder to become lucid when met again. The {#blank#}6{#/blank#} (volunteer) were then handed capsules. Each person got a high-dose (大剂量的) capsule, a low-dose capsule and a placebo (无效对照剂) capsule, but they couldn't tell which was which. On three occasions, they woke in {#blank#}7{#/blank#} middle of the night, took a capsule, imagined their dreamsign and went back to sleep. The high dose was most effective, causing lucid dreams in 42 per cent of participants. About 27 per cent {#blank#}8{#/blank#} (report) lucid dreams with the low dose and 14 per cent after taking the placebo capsule.

    The potential applications are {#blank#}9{#/blank#} (excite). "This new method has the success rate we need to be able to {#blank#}10{#/blank#} (proper) do research on lucid dreaming," says Denholm Aspy at the University of Adelaide in Australia.
