It is natural that young people are often{#blank#}1{#/blank#} （comfort） when they are with their parents.

    They say that their parents don't understand them. They often think that their parents are out of touch with modern ways,{#blank#}2{#/blank#}  they are too serious and too strict with their children, and that they seldom give their children a free hand.

   Parents often find{#blank#}3{#/blank#} difficult to win their children's trust and they always forget how they themselves felt when young.

   Young people like to act without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Adults worry{#blank#}4{#/blank#} （much） easily. Most of them plan things ahead.

    Young people make their parents angry with their{#blank#}5{#/blank#} （choose） in clothes, in entertainment and in music. But they do not mean to cause any trouble: It just shows that they feel cut off{#blank#}6{#/blank#} the adult's world, andthey have not yet been accepted into their world. That's why young people want to make a new culture of{#blank#}7{#/blank#} own. And if their parents do not like their music or entertainment or clothes or their way of speech, this will make the young people very happy.

    Sometimes youare so proud of yourself that you do not want your parents to say “yes” to what you do. All you want is{#blank#}8{#/blank#} （leave） alone and do what you like. It is natural enough, after{#blank#}9{#/blank#} （be）a child for so many years, when you were completely under your parents' control.

    If you plan to control your life, you'd better win your parents. If your parents see that you have{#blank#}10{#/blank#} high sense of responsibility, they will give you the right to do what you want to do.

    One day when I was five years old, my mother took me to a swimming pool. She wanted to teach me how to swim.{#blank#}1{#/blank#} (sad), I was almost drowned(淹死，溺死).{#blank#}2{#/blank#} I was rescued by a man, my mother was so {#blank#}3{#/blank#}(frighten) that she decided never to let me get close to a swimming pool again.{#blank#}4{#/blank#}, I thought quite differently. Instead of letting that horrible incident create more fear around water for me, I decided to become a good {#blank#}5{#/blank#}(swim). After I told my mother about that, she thought I was right and {#blank#}6{#/blank#}(agree). So I started to learn how to swim again. My mother became more careful and I was not in danger again. Later I became {#blank#}7{#/blank#} interested in swimming that I decided to compete in swimming events. After years of efforts, my dream came true. I was the first African American {#blank#}8{#/blank#}(win) an Olympic Gold Medal in swimming. I did so at both 2008 and 2012 Olympics.

    Now I spend much of my time {#blank#}9{#/blank#} (help) children learn how to swim. Hundreds of children each year drown in the United States.{#blank#}10{#/blank#} (learn) how to swim can prevent 80% of these tragedies.

    The passage is about a letter written by Li Qiang who is taking {#blank#}1{#/blank#} the prize that he won last year. At first he was nervous and {#blank#}2{#/blank#} (certain) about the journey. However, {#blank#}3{#/blank#} Wang Ping's guidance, Li Qiang was transported into the future safely.

    Hit by a lack {#blank#}4{#/blank#} fresh air, his head ached and he tried to make the necessary {#blank#}5{#/blank#} (adjust) to this new situation. Soon he was back {#blank#}6{#/blank#} his feet again and flew after Wang Ping in a hovering carriages {#blank#}7{#/blank#} (drive) by computer.

    Arriving at Wang Ping's house, Li Qiang was shown into a large room with a green wall {#blank#}8{#/blank#} (make) of trees, {#blank#}9{#/blank#} leaves provided the room with oxygen. {#blank#}10{#/blank#} (exhaust), Li Qiang slid into bed and fell fast asleep.

    One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he {#blank#}1{#/blank#} (find) that he had run out of salt. So Nick called to his son, "Go to the village and buy some salt, but pay a fair price for it: neither too much {#blank#}2{#/blank#}too little.

    His son looked surprised. "I can understand why I shouldn't pay too much, Father, but if I can pay less, {#blank#}3{#/blank#}not save a bit of money?

    "That would be a very {#blank#}4{#/blank#} (reason) thing to do in a big city, but it could destroy a small village like {#blank#}5{#/blank#} (us), Nick said.

    Nick's guests, {#blank#}6{#/blank#}had heard their conversation, asked why they should not buy salt more cheaply if they could. Nick replied, "The only reason a man would sell salt {#blank#}7{#/blank#}a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect for the sweat and struggle of the man who worked very hard to produce it."

    "But such a small thing couldn't {#blank#}8{#/blank#} (possible) destroy a village."

    "In the beginning, there was only {#blank#}9{#/blank#}very small amount of unfairness in the world, but everyone added a little, always {#blank#}10{#/blank#} (think) that it was only small and not very important, and look where we have ended up today."
