    中国瓷器
    ①中国瓷器是世界公认的伟大发明之一。它之所以名扬天下，主要在于其本身所包含的三项独创技术：胎质、瓷釉、烧结火候。
    ②中国瓷器的胎质大多具备一定的透明性，所谓有素肌玉骨之像。它的原料多为高岭土，无论东南沿海还是华中各省都有此土，尤其是在江西景德镇高岭村一带，风化了的白云母花岗岩蓄藏丰厚。也就是说，在中华大地取用制瓷原料是得天独厚的。
    ③瓷釉覆盖在瓷胎上，实际上就形成了一种复合材料。宋代以后，景德镇成为瓷业的主要生产地之一，就是因为这一带开始以“白云石”加入釉中，使瓷釉洁白又易于施加彩饰。
    ④烧结火候，主要是指瓷器烧成的温度。烧制陶器、砖瓦都在1000℃以下，瓷器则不然。据推测，早期瓷器的烧成温度就已经达到1200℃了。日本大阪大学美术史教授木村重信先生曾撰文：“尽管要通过1300℃高温煅烧，釉料仍不变色，纹样依然如故，这就是中国瓷器烧制技术上关键的秘密所在。”
    ⑤中国瓷器享誉世界，也在于它是科学技术与民间工艺美术技法完美结合的产物。传统细瓷早已形成一整套美化装饰的方式方法，不管是刻花、剔花，还是贴花、印花；也不管是堆雕、镂雕，还是镏金、戗金……均极尽缤纷艳丽，堪称巧夺天工。早期的纹饰简单、自然，完全由烧瓷艺人自行设计，例如水纹、云纹、花纹和兽纹等。盛唐以来，纹饰大量借鉴金属器皿、各种织物等图案，使瓷器的装饰意味更浓。宋代以后，瓷业工艺技法愈加精细，彩绘画面也刻意追寻名画师的笔意，有的春花烂漫，有的冬雪裹枝，有的高山流水，有的繁星满天……这无不增添了瓷器美的意蕴，
    ⑥中国瓷器还承载着丰厚的文化积淀。它的彩绘内容有来自民间传说、历史故事，也有“犀牛望月”、“龙凤吉祥”、“岁寒三友”等寓意丰富的图案。康熙年间，景德镇窑曾经烧制一组花卉瓷酒盅，薄胎青花，加彩题句，一盅一花一词。其中梅花盅题为“素艳雪凝树，清香风满枝”；杏花盅题为“青香和宿雨，佳色出晴烟”；桃花盅则题为“风花新社燕，时节归春浓”……瓷精，图美，词句优雅，在有限的空间中令人感受到无限的韵味。
    ⑦中国瓷器，实在是令人叹为观止。
    【小题1】第①段划线句中“主要”一词能否去掉?为什么?(3分)
    【小题2】第⑤段介绍纹饰时采用了            顺序。（1分）
    【小题3】第⑥段划线句主要运用什么说明方法?有什么作用?(3分)                                                            
    【小题4】第⑥段“在有限的空间中令人感受到无限的韵味”，“有限的空间”是指                     ，“无限的韵味”是指                      (3分)
    【小题5】从全文看，中国瓷器令人叹为观止的原因有哪些?(3分)

    How to be a Green One
    What does it mean to be green? “Green is more than just a c 76  .It also means taking special steps to protect the e77  --the water, the land , and the air we breathe. Why is green?

    R79  It!
    When you use less of something, you do a good thing for the earth. For example, a shorter shower means you use less water and less fuel(燃料) because your house uses fuel to run the water heater（加热器）that warms up the water.
    Reuse It !
    Sometimes we’re a little too willing to throw away the w80 and buy new things. Many times, you no l 81  need something, someone else just might need it. For example, if your baby brother grows out of toys, why not give them to a82  family who has a little kid?
    Recycle(回收) It!
    Recycling has n83 been easier. Many people will pick it up right in front of your house and they will need it. Tell your mum or dad become “Head of Recycling” for your house.
    Enjoy It!
    It’s true that p84  is a problem, but the earth is still a large and beautiful place for you to go and study. You can start by v85  the beautiful places in you home town. Go for a hike, visit local nature centres and gardens, climb up mountains and so on.
