Question

Britain’s seed(種子) 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(植物的)  gardens—will officially place 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(多樣的) 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 eating.
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 ten years 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 pressing 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（種類）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.
【小題1】What’s the final purpose of the Britain’s seed bank?

A．To collect enough money for the project.	B．To safeguard food crops.

D．the wild plants in places like India and China will never die out

【小題3】What does the underlined word “it” in paragraph 7 refer to?

A．The extinction of plant species.

C．Britain’s seed bank.

D．Kew Gardens’ next goal.

【小題4】Which of the following isn’t spoken about in the passage?

A．The global partnership of collecting wild plant species.

B．The temperature condition of the wild plant species in the bank.

C．The government’s support for the seed bank project by giving money.

Answer 1

【小題1】C
【小題2】B
【小題3】B
【小題4】C

解析試題分析：文章講述了在氣候變化，很多物種瀕臨滅絕的情況下，倫敦種子銀行的開辦、運營它所進行的“千年種子庫計劃”，具有重大意義。
【小題1】細節(jié)理解題。由第一段和第四段內(nèi)容可知，倫敦種子銀行旨在通過收集自然界的植物種子以達到保護自然界生物多樣性的目的。
【小題2】推理判斷題。由第三段Paul Smith的話可知，印度和巴西還沒有參與種子銀行捐種子的活動，故選B項。其他三項與文章內(nèi)容不一致。
【小題3】細節(jié)理解題。本文主要講的是倫敦種子銀行和它所進行的“千年種子庫計劃”，結(jié)合It所在句子可知，是這項計劃在和時間賽跑。因此選B。
【小題4】細節(jié)理解題。文章最后一段只是說實現(xiàn)下一個目標植物學(xué)家每年還需要很多資金，并沒提到政府的財政支持。
考點：科普環(huán)保類閱讀
點評：文章講述了倫敦種子銀行的開辦、運營它所進行的“千年種子庫計劃”。科普知識類文章結(jié)構(gòu)一般也是由標題(Headlines),導(dǎo)語(Introductions)?背景( Background)?主體(Main body)和結(jié)尾(Ends)五部分構(gòu)成。導(dǎo)語一般位于整篇文章的首段。背景交待一個事實的起因。主體則對導(dǎo)語概括的事實進行詳細敘述。這一部分命題往往最多，因此，閱讀時要把這部分作為重點。結(jié)尾往往也是中心思想的概括，并與導(dǎo)語相呼應(yīng)，命題者常在此要設(shè)計一道推理判斷
