题干

 Foods that are well known to you may not be familiar to people from different places around the world. Tourists and travelers often get to try some unfamiliar food. That is part of the fun of traveling. Here are four people's experiences with foreign food.

David King is a Chinese student in France. “I never had cheese or even milk before I came to France. Cows are seldom seen in my part of China. So there is no milk or milk products. I drank some milk when I first arrived in France. I hated it! I tried cheese, too, but I didn't like it. I love ice cream, though that's made from milk.”

Birgit is from Sweden. She traveled to Australia on vocation. "I was in a restaurant that was special in fish. I heard some other people order flake, so I ordered some, too. It was delicious! Later, I learned that flakes is an Australian name for shark. Now, whenever I see a new food, I try it on purpose. You know why? I remember how much I enjoyed flake.”

 Chandra is a dentist in Texas. She is from India. “ I'm afraid to try new foods because maybe there is beef in them. I'm a Hindu(印度教信徒)and my religion(信仰) stops me from eating meat from the cow. That's why I can't eat hamburgers or noodles with meatballs.”

Nathan is from the United States. He taught for a year in China. “My friend gave me some 100-year-old eggs to eat. I didn't like their appearance at all. The eggs were green inside, but my friends said the color was normal. Chinese people put something on fresh eggs. Then they put them in the earth for three months. So the eggs weren't really very old. Even so, I didn't want to touch them.”

阅读下文。完成下列各题。

高山上的守望者﹣﹣岳桦

    ①巍峨的长白山上,大森林垂直绵延2000多米。1100米以下是针阔混交林,金秋时节,绚烂缤纷;l100米一1800米之间是针叶林,树木挺拔参天,气势磅礴;过了1800米,森林放慢了脚步,这里恶劣的自然条件,使大部分树木没有胆量穿越,即便是傲风斗雪的青松也望而却步。然而岳桦却以勇敢和坚毅不屈的精神,顽强地在这里扎下了根,成为在蓝天白雪之间悄悄集结、静静展开的高山上的守望者。

    ②岳桦在植物分类上属于桦木科,桦木属,为落叶乔木植物。树皮呈灰黄白色,枝暗红褐色,幼枝暗绿色;冬芽呈矩圆形或卵球形,叶片薄,较硬,边缘呈不规则的锯齿状;花期为每年的5﹣6月,果期在8~9月。岳桦生长在寒湿地带的半阳坡山脊上,在我国分布于大小兴安岭、长白山等地,在俄罗斯东部、朝鲜、日本也有分布。

    ③岳桦生长地属于湿润性亚高山气候。冬季寒冷多风,夏季湿润多雨。降水量大而蒸发量小;年平均气温低,无霜期不足70天,生长季节短;风力强劲,每年有200多天的风力超过6级。这里土壤贫瘠,虽然土壤表层有机质含量较高,但10厘米以下土质疏松,腐殖质较少,角砾较多。

    ④在低海拔地区,尽管条件优越,但岳桦竞争不过云杉、冷杉等,只呈零星分布。随着海拔的升高,岳桦越来越占据优势地位,并在海拔1700米一2100米处形成东亚地区保存最为完整的岳桦林带,几乎为纯林。当海拔高于2loo米,由于受风、雪等因素的影响,岳桦以斑块状分布于高山苔原带。

    ⑤岳桦一年之内只有两个多月的生长期,生长期内又常常遭遇8级以上大风,因此。岳桦生长得十分谨慎也十分缓慢。一棵看起来只有手腕粗的岳桦,往往已有十几岁甚至几十岁。岳桦的兄弟姐妹(红桦、硕桦、黑桦等)高大笔直,在人们面前一直是美丽而又充满灵性的精灵。而岳桦几乎不足3米高,不过数寸粗,枝条虬曲,枝干大幅度倾斜,显得矮小卑微,弯曲丑陋。但岳桦的木质却异常的细密坚硬,成龄的岳桦木坚如磐石,入水即沉,其超乎寻常的硬度常常令初识者瞠目结舌。

    ⑥处在高海拔地区的岳桦林作为独特的自然生态系统,具有涵养水源、调节气候以及维护物种多样性等方面的生态功能。它们在忍受恶劣生存环境所带来的苦难的同时,用自己的根须牢牢地拢住了土壤,用自己的生命精心地护养着水源,用自己的身躯无私地庇护着动物。

    ⑦这就是高山上的守望者﹣﹣岳桦。它在艰难的磨砺中体现自己独特的魅力,以超凡脱俗的修炼证明了身形弱小未必就是卑微。
