　　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(批发商). “If you want to farm bamboo, it's hard to do without the young plants, and that's what we have，” she says proudly.

　　16．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.

　　17．What does Heinricher think of bamboo?

　　A．Fragile and affordable.

　　B．Productive and flexible.

　　C．Useful and earth-friendly.

　　D．Strong and profitable.

　　18．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

　　19．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.

　　B

　　All over my garden I've planted nothing but roses, because I especially love the flower. A close friend came for a visit the other day. I told her that she should pick a bunch of roses to beautify her bedroom. I promised that the smell of the roses would be wafted far, far away.

　　That girl friend of mine, walking into the garden in high spirits, smelt here and there, but in the end she didn't pick a single rose. I said that she could pick many flowers; I told her that I was not a flower farmer and didn't make a living out of them. Saying so, I raised the scissors for the sacrifice of the flowers, but she stopped me, crying no, no, no!

　　To cut such beautiful roses would hurt one, she said. With her hands seizing at my sleeves, she told me that by no means should they be cut. Roses are the smiling face of the earth, and who could be so iron-hearted as to destroy such a charming smile?

　　My mind was shocked: the ugly earth, the tough earth, the plain earth—it is for the reason of that smile that it wins the care and pity of people.

　　20．The writer plants nothing but roses in her garden probably because ________.

　　A．she can make money out of them

　　B．her friends like them

　　C．she enjoys the roses very much

　　D．the roses sell well

　　21．The underlined word “wafted” in Paragraph 1 is closest in meaning to “________”．

　　A．given off

　　B．lost

　　C．destroyed

　　D．thrown away

　　22．Why did the writer's close friend refuse to pick a single rose?

　　A．Because the roses were not beautiful.

　　B．Because she loved the roses very much.

　　C．Because she did not like this kind of roses.

　　D．Because the writer did not want to give her any.

　　23．What is the best title for the passage?

　　A．The Pity of People to the Roses

　　B．A Lover of Flowers

　　C．A Lovely Rose Garden

　　D．The Smiling Face of the Earth

　　答案

　　课时作业(十七)

　　.1.C　考查冠词用法。句意：第一印象最持久。毕竟，你不会再有机会去形成第一印象。第一空后有second，在此表示再一次机会，而不是表顺序，应用不定冠词；第二空中的第一印象是泛指，也不是表示顺序，又根据题干可以判断impression在此处是可数名词，可数名词单数表泛指时须用不定冠词，故选择C项。

　　2．A　考查非谓语动词。句意：他告诉我们是否去野营还在讨论当中。分析句子可知“whether ＋to do sth.”作宾语从句的主语，He told us 后省略了宾语从句的引导词that。

　　3．B　考查状语从句。句意：尽管Tim不经常锻炼，但他身材很好。前后是让步关系，故选B项。

　　4．B　考查倍数的表达。

　　5．A　考查动词短语辨析。句意：“对不起，现在我得挂断电话了。该上课了。”“好吧，等会儿我再打电话?！県ang up意为“猛地挂断，中止(与某人的)电话交谈”，符合语境。break up意为“(集会)结束，解散；(恋爱或婚姻中的男女)分手”；give up意为“放弃；认输；猜不出，交出；自首；泄露”；hold up意为“举起，支持，支撑，拦住，耽搁”。

　　6．B　考查would rather 的反意疑问句。

　　7．A　考查动词的时态。句意：我得去看医生，因为我近来一直咳嗽得很厉害。根据句子中的lately可知，设空处表示现在的事情，故用现在时态，排除B、C两项；D项表习惯性动作，故被排除。现在完成进行时表示动作从过去开始，持续到现在且现在还在进行。

　　8．A　考查省略。句意：如果这些食物好吃，我再去买些。否则，我就不去买了。if not意为“否则”；if any意为“若有的话”；whenever意为“无论什么时候”；无when not这种表达。根据句意，正确答案为A项。

　　9．B　考查虚拟语气及固定短语辨析。句意：由于天气不好，足球赛被要求推迟了。在It is required that…句型中，从句的谓语动词用“should ＋ 动词原形”，should可以省略，所以排除C和D两项。没有thank to这种用法，所以排除A项，正确答案为B项。

　　10．C　考查非谓语动词。rid of 是一个固定搭配，意为“使摆脱；使去掉”。switch from…to…也是固定搭配，意为“从……转向……”，其中to是介词，后面需跟名词或动名词形式。所以正确答案为C项。

　　11．D　考查非谓语动词。句意：她喜欢用手洗衣服而不愿用洗衣机洗。固定表达prefer to do sth. rather than do sth.意为“宁可做……而不做；喜欢做……而不做……”，所以正确答案为D项。

　　12．D　考查副词用法。句意：奇怪的是，这两个人看起来这么相像，以至于几乎所有人都认为他们是双胞胎兄弟。too much 后跟不可数名词或单独使用，意为“太多”；much too后跟形容词或副词原级，意为“太，很”；没有such much这种表达；so后可跟形容词或副词，所以正确答案为D项。

　　13．C　考查副词辨析。根据上下文可知是因果关系，因此选C。

　　14．A　考查动词的时态。句意：约瑟夫从上个月就开始上夜校，但是他还不会用俄语说“你叫什么名字”。本题从时间状语“自从上个月开始”可知需用现在完成时，又因为说话时他还在继续上课，所以要用现在完成进行时。

　　15．C　考查交际用语。句意：“这张照片我保存行吗？”“恐怕不行?！贝鹩镉ξ窬芫?。A、B、D均不符合题意。

　　.A

　　本文是一篇记叙文。其大意是说Jackie Heinricher创办了一家生意独特的公司——出售对地球环境有很大好处的植物竹子。文章还介绍她栽种竹子的艰辛历程。

　　16．A　细节理解题。根据文章的最后一句“If you want to farm bamboo, it's hard to do without the young plants, and that's what we have…”可知没有小竹子很难广泛地栽种竹子。

　　17．C　推理判断题。根据第三段最后两句“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.”可推知竹子是“有用的”以及“环保的”。

　　18．A　词义猜测题。由renewable的构成可知其词根是new，加后缀-able意思是“能够更新的”；加前缀re-意思是“再，又，重新”，由此可知本题选A。

　　19．B　推理判断题。通读最后一段可知Heinricher的生意很成功，前几段讲了她的艰辛的历程，故本题选B。

　　B

　　本文为夹叙夹议文。主要讲述了“我”种了一园的玫瑰，朋友来访时，“我”建议她可以把花摘回，放在屋里，可朋友说玫瑰是地球的笑脸，决不能采摘。

　　20．C　细节理解题。根据第一段第一句“All over my garden I've planted nothing but roses, because I especially love the flower.”可知，“我”种玫瑰是因为“我”非常喜欢玫瑰，故选C项。

　　21．A　词义猜测题。根据画线词所在句“…the smell of the roses would be wafted far, far away.”可猜出玫瑰的香味应该能散发到很远，故选A项，give off意为“散发出”。B项意为“遗失，失败”；C项意为“毁灭”；D项意为“扔掉”。

　　22．B　推理判断题。根据第二段第一句“That girl friend of mine, walking into the garden in high spirits, smelt here and there…”以及第三段第三句“Roses are the smiling face of the earth…”可知，作者的这个朋友应该是非常喜欢玫瑰，故选B项。

　　23．D　主旨大意题。综观全文，以及倒数第二段最后一句“Roses are the smiling face of the earth…such a charming smile？”以及最后一段“My mind was shocked: the ugly earth, the tough earth, the plain earth—it is for the reason of that smile that it wins the care and pity of people.”可知选D项。
