Of the three major drinks of the world—tea, coffee and cocoa—tea is consumed by the {#blank#}1{#/blank#} (large) number of people.

    China is the homeland of tea. Human cultivation of tea plants dates back to two thousand years ago. Tea from China, along {#blank#}2{#/blank#}her silk and porcelain, began to be known to the world more than a thousand years ago and since then it{#blank#}3{#/blank#} (be) an important Chinese export.

    At present more than forty countries in the world grow tea with Asian countries，{#blank#}4{#/blank#}  (produce) 90% of the world's total output. All tea trees in other countries have their origin directly or indirectly in China. The word for tea leaves or tea as{#blank#}5{#/blank#} drink in many countries are derivatives(衍生物)from the Chinese character “cha”. The Russians call it “cha'i”, {#blank#}6{#/blank#}sounds like “chaye”(tea leaves) as it is pronounced in northern China, and the English word “tea” sounds similar to the pronunciation of{#blank#}7{#/blank#} (it) counterpart（对应物） in Xiamen. The Japanese character for tea is written{#blank#}8{#/blank#} (exact) the same as it is in Chinese, though{#blank#}9{#/blank#} (pronounce) with a slight difference. The habit of tea drinking spread to Japan in the 6th century, but it was not introduced to Europe and America till the 17th and 18th centuries. Now the number of tea{#blank#}10{#/blank#} (drink) in the world is still on the increase.

    For several billion years after the "Big Bang", the earth was still just a cloud of dust. What it was to {#blank#}1{#/blank#} was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so {#blank#}2{#/blank#} that it was not clear whether the shape would last or not.

     {#blank#}3{#/blank#} eastward, you'll pass mountains and thousands of lakes and forests, as well as wide rivers and large cities. Some people have the idea {#blank#}4{#/blank#} you can cross Canada in less than five days, but they forget the fact that Canada is 5500 kilometers from coast to coast. Here in Vancouver, you're in Canada's warmest part. People say it is Canada's most beautiful city. {#blank#}5{#/blank#} by mountains and the Pacific Ocean. Its population is increasing rapidly. The coast {#blank#}6{#/blank#} of Vancouver has some of the oldest and most beautiful forests in the world.

    However, this was not easy. When they first arrived in Gombe in 1960, it was unusual for a woman to live in the froest. {#blank#}7{#/blank#} after her mother came to help her for the first few months {#blank#}8{#/blank#} she allowed to begin her project. Her work changed the way people think about chimps. For example, one important thing she discovered was that chimps hunt and eat meat. Until then everyone {#blank#}9{#/blank#} thought chimps ate only fruit and nuts. She also discovered how chimps communicate with each other, and her study of their body language helped her {#blank#}10{#/blank#} their social system.

    It was getting dark when I got home. It was cold and I {#blank#}1{#/blank#}(wear) a coat. I walked up to the door and put my hand into my pocket {#blank#}2{#/blank#}(take) out my key {#blank#}3{#/blank#} I couldn't find it. I suddenly remembered that I {#blank#}4{#/blank#}(leave) it on my desk in the office. It really didn't make any difference. I knew my wife {#blank#}5{#/blank#}(be) at home and the children must have come back from school by now, so I {#blank#}6{#/blank#}(knock) at the door.

    There was no answer, so I knocked again. I continued knocking at the door for some time. I {#blank#}7{#/blank#}(get) angry. Then I remembered something the office boy had told me at noon. He said that my wife {#blank#}8{#/blank#}(phone) saying that she {#blank#}9{#/blank#}(go) shopping in the afternoon with the children.

    There was only one thing for me to do: I had to climb in {#blank#}10{#/blank#} a window.

    She looks like any other schoolgirl, fresh-faced and full of life. Sarah Thomas is looking forward to the challenge of her new A-level course. But unlike her school friends, 16-year-old Sarah is not spending half-term rest. Instead, she is earning £6500 a day as {#blank#}1{#/blank#}model in New York.

    Sarah {#blank#}2{#/blank#}(tell) that she could be Britain's new supermodel{#blank#}3{#/blank#} (earn) a million dollars in the next year. Her father Peter, 44, wants her to give up school to model full-time. But Sarah, {#blank#}4{#/blank#}has taken part in shows along with top models, wants to prove that she has brains as well as beauty. She is determined to carry on with her{#blank#}5{#/blank#} (educate).

    She has turned down several {#blank#}6{#/blank#} (invite) to star at shows in order to concentrate on her studies. After school she plans to take a year off to model full-time before going to university to get a degree {#blank#}7{#/blank#}engineering or architecture.

    Sarah says, "My dad thinks I should take the offer now. {#blank#}8{#/blank#}at the moment, school comes first. I don't want to get too {#blank#}9{#/blank#} (absorb) in modeling. It is certainly fun that the lifestyle is a little{#blank#}10{#/blank#} (real). I don't want to have nothing else to fall back on when I can't model any more."
