Question

8．Britain's seed bank，the only one in the world aiming to collect all of the planet's wild plant species，has reached its goal of banking 10 percent by 2010．
The Millennium Seed Bank Project，run by Kew Gardens-one of the oldest botanical gardens-will officially deposit the 24，200th species on Thursday，a pink，wild banana from China．
More than 50 countries are now on board with Kew's giant task but vast places of the globe，including India and Brazil，still need to join in and donate seeds，director Paul Smith said．
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds．Its goal is to help protect the planet's bio-diversity during a time of climate change．
The wild banana seed is under threat of extinction（灭绝） in southwest China from agricultural development．It is a vital food source for Asian elephants and important for growing bananas for human consumption．
Stored at minus-20 degrees centigrade，so they can last for thousands of years，the seeds await the day that scientists hope never comes-when the species no longer exist in the wild．
It is a race against time，Smith said，because in the last decade alone，20 plants held in the bank have already been wiped out in the wild．He estimates that between a third and a quarter will become extinct this century．
"It is urgent and it is happening now．An area，the size of England，is cleared of primary vegetation（植被）every year．"Smith said．
Because most of the world's food and medicines come from nature，protecting wild plant species is quite important，scientists say．There are already many other seed banks safeguarding food crops，which only account for 0.6 percent of plant diversity．
For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year，or a further 100 million pounds on top of the 40 million they have already been granted．
56．What's the final purpose of the Britain's seed bank？C
A．To collect enough money for the project．
B．To safeguard food crops．
C．To protect wild plants from extinction．
D．To help scientists study wild plants．
57．The wild banana seed in China is in danger because ofA．
A．the expanding of farming work          
B．the climate change in this area
C．the large number of Asian elephants      
D．human's large consumption
58．We can learn from the passage thatB．
A．the seeds in the bank can be used now and then all over the world
B．India and Brazil haven't joined in the Seed Bank Project at present
C．there is only one seed bank in the world at present
D．the wild plants in places like India and China will never die out
59．What does the underlined word"it"in paragraph 7 refer to？B
A．The extinction of plant species．
B．The Millennium Seed Bank Project．
C．Britain's seed bank．
D．Kew Gardens'next goal．
60．Which of the following information isn't mentioned in the passage？C
A．The global partnership of collecting wild plant species．
B．The temperature condition of the conservative wild plant species．
C．The government's financial support for the seed bank project．
D．Scientists'concern on the extinct wild plant species．

Answer 1

分析 本文为环保类文章，介绍了英国种子公司为保护濒危野生植物所做出的举措及它们的最新进展．

解答 56---60 CABBC
56．答案C．细节理解题．由第一段"Britain's seed bank，the only one in the world aiming to collect all of the planet's wild plant species"和第四段"The wild banana seed is under threat of extinction（灭绝） in southwest China from agricultural development"可知，伦敦种子银行旨在通过收集自然界的植物种子以达到保护自然界生物多样性的目的．
57．答案A．细节理解题．由第四段第一句"The wild banana seed is under threat of extinction（灭绝） in southwest China from agricultural development"可知，这种香蕉在中国西南部面临灭绝是因为农业的发展，故本题选A项．
58．答案B．推理判断题．由第二段Paul Smith的话"More than 50 countries are now on board with Kew's giant task but vast places of the globe，including India and Brazil，still need to join in and donate seeds，director Paul Smith said"可知，印度和巴西还没有参与59．种子银行捐种子的活动，故选B项．其他三项与文章内容不一致．
59．答案B．细节理解题．本文主要讲的是伦敦种子银行和它所进行的"千年种子库计划"，结合It所在句子可知，是这项计划在和时间赛跑，故此题选B．
60．答案C．细节理解题．文章最后一段"For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year，or a further 100 million pounds on top of the 40 million they have already been granted"，只是说实现下一个目标植物学家每年还需要很多资金，并没提到政府的财政支持．

点评 健康环保类文章可分为三部分：第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；第三部分是结尾段，对文章的主题进行归纳总结．这类文章多用一般现在时，而且一般多使用客观性词语表述．有时为了强调客观性，也常使用被动语态．
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近．由于此类文章缺乏故事情节，很多同学对此类文章感到费解．但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题．
