A fisheries biologist,Heinricher,47,planned to work in the salmon industry in Seattle,where she lived with her husband.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 (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 44 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. ()5.What would be the best title for the passage? A.Bamboo:the Earth-friendly material B.The success of Boo-Shoot Gardens C.Saving the planet with bamboo D.Heinricher's bamboo garden 五、书面表达(10分) 假如你是李华，你的英国笔友T©加对环保很感兴趣，他想了解你所在城市的环保情况。请你 根据以下要点提示，给他写一封电子邮件。 要点提示： 1.人们在日常生活中采取的环保行动，如垃圾分类、绿色出行等： 2.政府采取的环保措施，如制定法律、关闭污染工厂等： 3.你对未来坏保的期望。 要求： 4.包含所有要点提示，可适当发挥： 5.语言表达准确，语意通顺、连贯： 6.词数：80-100。开头和结尾已给出，不计入总词数。 Dear Tom, How's it going?I'm glad to tell you something about the environmental protection in my city.
