B. Choose the best answer(选择最恰当的答案)(每题2分,6题,共12分)★
In the western part of Ghana(加纳), a small company is making something that would surprise most people: bicycles built entirely from bamboo. The project was started by Kwame, a young engineer whose goal was simple—to create affordable, useful transport for local people without harming the environment.
Bamboo is one of the fastest-growing plants on Earth. A single shoot can grow several centimetres in a single day, and a mature grove can be harvested without being destroyed, since the roots remain in the ground and produce new shoots almost immediately. This makes bamboo one of the most sustainable materials any manufacturer could hope to find. The bikes themselves are built by hand in a small open-air workshop, where trained workers join the bamboo tubes together using natural fibre(天然纤维) and a special glue made from plant oils. Each bicycle takes roughly three days to complete.
The idea has attracted attention far beyond Ghana. Environmental groups across Africa, Asia, and Europe have visited Kwame's workshop to see how the project works. Several
universities have invited him to speak about sustainable design. 53 He believes that if bamboo bikes can succeed in one community, the same thinking can be applied to other products that currently rely on plastic or metal.
However, not everyone is convinced. Some engineers point out that bamboo bikes may not hold up as well as metal ones under heavy loads or in very wet conditions. Kwame admits this is a fair concern, and his team is currently testing new ways to strengthen the bamboo to make each bike longer-lasting and more reliable in different environments.
For now, hundreds of bamboo bikes are already on the roads of rural Ghana. For the people who ride them, the choice is not just about transport—it is about showing that protecting the environment and building a decent(体面的) life can go hand in hand.
()51. According to Paragraph 2, what makes bamboo such a good material for building bikes?
A. It is cheaper to import than metal from other countries.
B. It grows back very quickly after being harvested.
C. It is the hardest natural material found in West Africa.
D. It can be painted in any colour without special tools.
()52. According to Paragraphs 1 and 2, which of the following is TRUE about how the bikes are made?
A. The bikes are produced by machines in a large factory.
B. Each bike is completed in less than one day.
C. The glue used to join the bamboo parts comes from plant oils.
D. The bamboo tubes are imported from other countries.
()53. Which of the following can be placed in the blank " 53 "?
A. Kwame has decided to stop making bamboo bikes and focus on other projects.
B. Kwame is now looking for ways to export the bikes to wealthier countries.
C. Kwame sees the bamboo bike project as more than just a local solution.
D. Several universities have already started making bamboo bikes themselves.
()54. What concern do some engineers raise about the bamboo bikes?
A. They cost more to produce than metal bikes.
B. They may not be strong enough in all conditions.
C. They are too difficult for ordinary people to repair.
D. They take much longer to build than expected.
()55. The underlined word "reliable" in Paragraph 4 most likely means "".
A. expensive B. popular C. dependable D. dangerous
()56. What is the author's likely attitude towards the bamboo bike project?
A. Strongly negative—the project has too many problems to succeed.
B. Completely neutral—the author presents no personal opinion at all.
C. Mostly positive—the project is presented as creative and worth supporting.
D. Disappointed—the author thinks Kwame should have chosen a different material.

点拨:52题,C.原文第二段明确写道"using natural fibre and a special glue made from plant oils",C项"The glue used to join the bamboo parts comes from plant oils"与原文直接对应。A项"produced by machines in a large factory"与原文"built by hand in a small open-air workshop"矛盾;B项"completed in less than one day"与"each bicycle takes roughly three days"矛盾;D项"bamboo tubes are imported"原文未提及,且文章强调使用当地资源。
54题,B.原文第四段写道"Some engineers point out that bamboo bikes may not hold up as well as metal ones under heavy loads or in very wet conditions.",B项"may not be strong enough in all conditions"是对原文的概括。A项"cost more to produce"原文未提;C项"too difficult to repair"原文未提;D项"take much longer to build"原文说的是"three days",并未指出"比预期长得多"。

【分析】
本题为英语阅读理解题，需通过定位原文信息解答各题型：1.第51题为细节理解题，定位第二段找竹子作为制作自行车好材料的原因；2.第52题为细节理解题，定位第二段制作过程描述，逐一排除错误选项；3.第53题为推理判断题，结合第三段项目影响力及Kwame的观点推断空白内容；4.第54题为细节理解题，定位第四段工程师的担忧匹配选项；5.第55题为词义猜测题，结合第四段上下文推测划线词含义；6.第56题为作者态度题，结合全文对项目的描述判断作者态度。
【解析】
51题：根据第二段“Bamboo is one of the fastest-growing plants on Earth...a mature grove can be harvested without being destroyed...produce new shoots almost immediately”，可知竹子收割后能快速再生，对应选项B；A、C、D原文未提及，排除。
52题：根据第二段“built by hand in a small open-air workshop”“takes roughly three days to complete”“using natural fibre and a special glue made from plant oils”，可知A、B、D均错误，选项C与原文一致，正确。
53题：第三段提到项目吸引多国环保组织、大学邀请演讲，Kwame认为该思路可应用到其他产品，说明他将项目视为不止本地的方案，对应选项C；A、B、D原文未提及，排除。
54题：根据第四段“Some engineers point out that bamboo bikes may not hold up as well as metal ones under heavy loads or in very wet conditions”，可知工程师担心竹子车在各种环境下不够耐用，对应选项B；A、C、D原文未提及，排除。
55题：第四段提到“testing new ways to strengthen the bamboo to make each bike longer-lasting and more reliable”，longer-lasting与reliable并列，结合语境，reliable意为“可靠的”，对应选项C；A、B、D不符合，排除。
56题：全文提到项目结合环保与体面生活，已有数百辆投入使用，作者对项目持肯定态度，对应选项C；A、B、D不符合，排除。
