students who learnt business skills by operating their own banks.

In December 1987，the Twiglet Bank was opened at an Elementary School in Miami,Florida. It is a real bank that accepts money for savings and makes loans, and it is operated by students between 10 and 12 years old. The bank is open for one hour two days a week.Students can put their money into the bank and withdraw it as they wish. Officials from a local bank helped the students start the bank. They trained twenty-three of ther to do all the different kinds of bank jobs, from counting money to guarding the bank. The students needed money to start the bank. They raised more than $ 2,000 by selling 50-dollar shares in the bank to parents, teachers, the local bank workers, and customers.

Organizing and operating the bank has taught the children a lot about the banking business. They have learned about raising and investigating money and how to use computers and other banking equipment. They have also learned how to ask for a job and to be responsible for their jobs.

recent invention, only about 10,000 years old. Many crop plants are rather new additions to our diet: broccoli (a flowering mutant of kale) is thought to be only 500 years old. Most innovation is far more recent still. Although Austrian monk Gregor Mendel's pea plant experiments quietly laid the basic foundations of genetics in the mid-19th century, his work was rediscovered and applied to crop breeding only at the beginning of the 20th century. Further advances have steadily accumulated. The 1940s saw the identification of DNA as genetic material and the adoption, by commercial breeders, of genetic modification - typically by applying chemicals or radiation to DNA to try to make plants with advantageous characteristics. The modifications ultimately led to the green revolution of the 1960s and 1970s, during which time global wheat yields tripled. The 1980s and 1990s saw the commercial adoption of agricultural biotechnology, which has allowed breeders to introduce specific genes into crops from the same or different species. In 2004 the first plant genome was fully sequenced, and since then the number of plant gene sequences in GenBank, the public repository for gene sequence information, has been doubling every two years. Our knowledge is increasing exponentially, as it has been in other fields such as semiconductors and cellular telephony. Our challenge is to increase agricultural yields while decreasing the use of fertilizer, water, fossil fuels and other negative environmental inputs. Embracing human ingenuity and innovation seems the most likely path. Plants did not evolve to serve humans, and their sets of genes are incomplete for our purposes. The integral role of modifying genes is obvious to all breeders, though sometimes painfully absent from the public's understanding of how modern agriculture succeeds. All breeding techniques, from before Mendel's time until today, exploit modifications to plant DNA. These modifications can take the form. of mistakes or mutations that occur during natural cell division in the wild; the natural but random movement of DNA sequences from one part of a plant's genome to another; or the more precise insertion of known gene sequences using biotechnology. In all these cases, plant genes are moved within or across species, creating novel combinations. Hybrid genetics - the combination of different versions of the same gene – has resulted in spectacular yield increases. Largely as the consequence of using hybrid seed varieties, corn yields in the U.S. have increased more than 500 percent in the past 70 years. Questions 6-10 are based on Passage Two.

The Gene Industry

Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes that might be used to mine valuable trace metals from ocean water". They have already demanded and won the right to patent new lifeforms.

Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.

Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain？ Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us？ Should we attempt to eliminate "inferior" people and breed a "super-race"？ (Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories.) Should we produce soldiers to do our fighting？ Should we use genetic forecasting to pre-eliminate "unfit" babies？ Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidney, lives or hands？

Wild as these notions may sound, every one has its advocates (and opposers) in the scientific community as well as its striking commercial application.-As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God'？ "Broad Scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created".

A．using metal-hungry microbes

B．making use of enzymes

C．adjusting the engine

D．patenting new life forms
