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（滅絕） 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 本文為環(huán)保類文章，介紹了英國種子公司為保護(hù)瀕危野生植物所做出的舉措及它們的最新進(jìn)展．

解答 56---60 CABBC
56．答案C．細(xì)節(jié)理解題．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（滅絕） in southwest China from agricultural development"可知，倫敦種子銀行旨在通過收集自然界的植物種子以達(dá)到保護(hù)自然界生物多樣性的目的．
57．答案A．細(xì)節(jié)理解題．由第四段第一句"The wild banana seed is under threat of extinction（滅絕） in southwest China from agricultural development"可知，這種香蕉在中國西南部面臨滅絕是因?yàn)檗r(nóng)業(yè)的發(fā)展，故本題選A項(xiàng)．
58．答案B．推理判斷題．由第二段Paul Smith的話"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，印度和巴西還沒有參與59．種子銀行捐種子的活動，故選B項(xiàng)．其他三項(xiàng)與文章內(nèi)容不一致．
59．答案B．細(xì)節(jié)理解題．本文主要講的是倫敦種子銀行和它所進(jìn)行的"千年種子庫計劃"，結(jié)合It所在句子可知，是這項(xiàng)計劃在和時間賽跑，故此題選B．
60．答案C．細(xì)節(jié)理解題．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"，只是說實(shí)現(xiàn)下一個目標(biāo)植物學(xué)家每年還需要很多資金，并沒提到政府的財政支持．

點(diǎn)評 健康環(huán)保類文章可分為三部分：第一部分一般是文章的首段，主要用來提出文章的主題，即文章想要闡述、說明的主要內(nèi)容；第二部分是文章的主體，可由若干個段落組成，對文章的主題進(jìn)行展開說明；第三部分是結(jié)尾段，對文章的主題進(jìn)行歸納總結(jié)．這類文章多用一般現(xiàn)在時，而且一般多使用客觀性詞語表述．有時為了強(qiáng)調(diào)客觀性，也常使用被動語態(tài)．
從近幾年的考試題來看，科普環(huán)保類的文章越來越與人們的實(shí)際生活相接近．由于此類文章缺乏故事情節(jié)，很多同學(xué)對此類文章感到費(fèi)解．但一般的科普類文章都是就事論事，需要邏輯推理和想象的時候較少，因此此類閱讀題也沒有同學(xué)們想象中的那么難，只要多加訓(xùn)練，就能較好地答題．
