Question

阅读理解 Saving the Planet with Earth-Friendly Bamboo Products 　　Jackie Heinricher's love affair with bamboo started in her backyard．“As a child, I remember playing among the golden bamboo my dad had planted, and when there was a slight wind, the bamboos sounded really musical．” 　　A fisheries biologist, Heinricher, 47, planned to work in the salmon industry in Seattle, where she lived with her husband, Guy Thornburgh, but she found it too competitive．Then her garden gave her the idea for a business：She'd planted 20 bamboo forests on their seven-acre farm． 　　Heinricher started Boo-Shoot Gardens in 1998．She realized early on what is just now beginning to be known to the rest of the world．It can be used to make fishing poles, skateboards, buildings, furniture, floors, and even clothing．An added bonus：Bamboo absorbs four times as much carbon dioxide as a group of hardwood trees and releases 35 percent more oxygen． 　　First she had to find a way to mass-produce the plants－a tough task, since bamboo flowers create seed only once every 50 to 100 years．And dividing a bamboo plant frequently kills it． 　　Heinricher appealed to Randy Burr, a tissue culture expert, to help her．“People kept telling us we'd never figure it out,”says Heinricher．“Others had worked on it for 27 years!I believed in what we were doing, though, so I just kept going．” 　　She was right to feel a sense of urgency．Bamboo forests are being rapidly used up, and a United Nations report showed that even though bamboo is highly renewable, as many as half of the world's species are threatened with dying out．Heinricher knew that bamboo could make a significant impact on carbon emissions(排放)and world economies, but only if huge numbers could be produced．And that's just what she and Burr figured out after nine years of experiments－a way to grow millions of plants．By placing cuttings in test tubes with salts, vitamins, plant hormones, and seaweed gel, they got the plants to grow and then raised them in soil in greenhouses． 　　Not long after it, Burr's lab hit financial difficulties．Heinricher had no experience running a tissue culture operation, but she wasn't prepared to quit．So she bought the lab． 　　Today Heinricher heads up a profitable multimillion-dollar company, working on species from all over the world and selling them to wholesalers．“If you want to farm bamboo, it's hard to do without the young plants, and that's what we have,”she says proudly． (1) What was the main problem with planting bamboo widely? [　　] A． They didn't have enough young bamboo． B． They were short of money and experience． C． They didn't have a big enough farm to do it． D． They were not understood by other people． (2) What does Heinricher think of bamboo? [　　] A． Renewable and acceptable B． Productive and flexible． C． Useful and earth-friendly． D． Strong and profitable． (3) The underlined word“renewable”in Paragraph 6 probably means“________”． [　　] A． able to be replaced naturally B． able to be raised difficultly C． able to be shaped easily D． able to be recycled conveniently (4) What do you learn from the passage? [　　] A． Heinricher's love for bamboo led to her experiments in the lab． B． Heinricher's determination helped her to succeed in her work． C． Heinricher struggled to prevent bamboo from disappearing． D． Heinricher finally succeeded in realizing her childhood dream．

Answer 1

答案：1．A;2．C;3．A;4．B;
解析：

Jackie Heinricher开始爱上了她后院的竹子。“在小时候，我记得我在爸爸种植的金竹旁玩耍，当有微风吹过时，竹子发出了令人难以置信的音乐。这就是我的魔幻区域。” 　　Heinricher，47岁是通过培训的渔业生物学家，计划在西雅图干鲑鱼工业，在那里她与丈夫盖伊索恩伯勒生活，但她发现这个行业竞争力太强了。她的花园给了她办一个业务的想法：她要在她的7英亩的农场上种植20棵竹子，并已取得了一些成功繁殖的成果，在那些小花园里(每小时成长二英寸，成为了一个景观，好像没有那么快)。 　　Heinricher于1998年承包了竹笋花园。她意识这些只是刚刚开始：令人难以置信的是竹子多才多艺，非常环保。它可以用来制造捕鱼杆，滑板，建筑，家具，地板，甚至是服装和床上用品(织物软丝绸)。另外一个好处：竹子作为一种硬木树可吸收四倍二氧化碳，并释放更多的氧气，大概超过百分之三十五。如果Heinricher可以利用她的园艺技能来推动绿色环保事业，这样会更好。 　　起初，她不得不找到一种方法，来大规模的生产，这是一项艰巨的任务，因为竹子花产生种子每50到100年才一次。所以竹子工厂经常没有材料可用。 　　Heinricher呼吁组织培养专家兰迪伯尔帮助她。“人们不停地说我们没有成果出来”Heinricher说。“很多人工作了27年，我相信我们所做的，所以，我们只要坚持，不放弃。” 　　她是感觉到有一种紧迫感。竹林正在迅速枯竭，联合国的一份报告表明，即使是高度可再生竹子，有多达一半的世界物种濒临灭绝。Heinricher知道竹子可以对二氧化碳排放量和世界经济有重大的影响，但前提是可以大量生产。而这只是她和伯尔经过9年实验得出的结论－可以让植物成千上万的增长。把剪好的竹子放入试管中，与盐，维生素，植物激素，和海藻胶混合，植物发芽了，然后拿出来，把他们放在温室的土壤中。 　　在破解了代码之后，伯尔的实验室遇到了财政问题。Heinricher在组织培养操作中没有任何经验，但她不准备辞职。于是，她购买了实验室。“这是一场可怕的挑战，”她说。“我从5个员工干到了55个员工[包括伯尔]。我不怎么睡觉。一夜之间就像在新兵训练营里一样。有时候，我奇怪我怎么会在这里。” 　　今天Heinricher拥有了一个盈利数百万美元的公司，与世界各地有贸易往来。“如果你想做农场竹子业，没有植株很难完成，这就是我们所经历的”她说。
