Botany （植物学） , the study of plants, occupies a particular position in the history of human knowledge．For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest （模糊的）） of insights．It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient．This is logical．Plants are the basis of the food pyramid for all living things even for other plants．They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes．Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each．To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all．

Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows．Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple．When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season—the first, great step in a new association of plants and humans was taken．Grains were discovered and from them flowed the wonder of agriculture: cultivated crops．From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away．

1.What does the writer mean when he says "This is logical" in the first paragraph?

A．Human knowledge of plants is well organized and very detailed．

B．It is not surprising that early humans had a detailed knowledge of plants．

C．There is no clear way to determine the extent of our ancestor's knowledge of plant．

D．It is reasonable to assume our ancestors behave much like people in pre-industrial societies．

2.According to the passage, general knowledge of botany begun to fade away because ____．

A．people no longer value plants as a useful resource

B．direct contact with a variety of plants has decreased

C．botany is not recognized as a special branch of science

D．research is unable to keep up with the increasing number of plants

3.We learn that the first great step toward the practice of agriculture is____．

A．the changing diets of early humans

B．the development of a system of names for plants

C．the invention of agricultural implements （工具） and machinery

D．the discovery of certain grasses that could be harvested and replanted

4.Human would depend on the controlled production of a few plants for living with

A．the knowledge of plants

B．the discovery of certain grasses

C．the development of machinery

D．the appearance of agriculture

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.

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.

C. To protect wild plants from extinction.        D. To help scientists study wild plants.

2.The wild banana seed in China is in danger because of _______.

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

3. We can learn from the passage that _______.

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

4. What does the underlined word “it” in paragraph 7 refer to?

A. The extinction of plant species.           B. The Millennium Seed Bank Project.

C. Britain’s seed bank.                      D. Kew Gardens’ next goal.

5.Which of the following information isn’t mentioned in the passage?

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.
