The Gene Industry
Major companies are already in pursuit of commercial applications of the new biology .They dream of placing nxymse（酶）in the automobile to monitor exhaust nad send data om pollution to a microprocessor that will then adjust the engine .they speak of what the New York Time calls"metal-hungry microbse（微生物）that might be used to mine valuable trace metals from ocean water".They have already demanded and won the right to patent new liteforms .
Nervous critics,including many scientists,worry that there if

corporate,national,international,and inter-scientific rivalry in the entire biotechnological field.They create images not of oil spills(溢出）,but of "microbe spills" that could spread disease and destroy entire

populations,The creation and accidental release of extremely poisonous microbes,however,if only one cause for https://www.360docs.net/doc/ad11788150.html,pletely 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 fod chain? should we biologically alter workers to fit the job requierement,for example,creating pilots with faster reaction times or assemblyline 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 soom issue form our fighiting?Should we use genetic forecasting to preeliminate "unfit" babies?Should we grow reserve organs for ourselves ,each of us having,as it were ,a "savings bank " full of spare kidney ,livers ,or hands?

Wild as thses notions may sound,every one has itd 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 sa assembly lines ,automobiles,vaccines, computers

and all the other technologies. As each new genetic advance b***mes commercially practical, a new consumer need will be exploitde and a market for the new technology will be created."
11. According to the passage, the new biology could potentially solve the pollution problem of automobiles by
A using metal-bungry microbes.

B making use of enzymes.
C adjusting the engines.
D patenting new lifeforms .
12. According to the passage, which of the following would most probably worry the critics of the following would most probably worry the critics of the new biology?
A The microbes in the ocean warter.
B The creation and application of biological solar cells
C The accidental oil spills.
D The unexpected release of destructive micrbes.
13. Which of the following possibilities of the biotechnological applications is NOT mentioned in the third paragraph?
A Developing a savings bank of one"s orangs.
B Breeding soldiers

for a war .
C Producing people with cow-like stomachs.
D Using genetic forecasting to curt diseases.
14. According to the passage,Hitler had

attempted to
A biologically change the pilots to win the war .
B develop genetic farming for increasing

the food supply .
C kill the people he thought of as being inferior.
D encourage the development of genetic weapons for the war.
15. What is the implication of the sratement of Jeremy Rifkin and Ted Howard?
A The commercial applications of genetic engineering are inevitable.
B Large-scale genetic engineering has occurred in the Untied States.
C Americans are proud of their computers,automobiles and genetic technologies.
D The potential application of each new genetic advance should be controlled.

Perfect Competition
Perfect competition exists in an industry that contains many relatively samll firms producing identical products.The most importhant characteristic(特征) of a perfectly competitive industry if that no single firm has any control over prices.This important characteristic follows from two assumptions(假设).First, a competitive industry is composed of many firms, each being very samll relative to the size of the

industry .S***nd ,every firm in a perfectly competitive

industry producse exactly the same product.
Firms in perfectly competitive industries do not differentiate(区分) their products, nor do they make decisions about

price.Rather,each firm takes prices as given-that is ,as determined in the market by the laws of supply and demand -and decides olny how much to produce and how to produce

it.Given the availability(可得性) of perfect substitutes, any product priced over the market price will not be sold .
In perfect competition we also assume that firms can freely enter and exit the industry.The assumption of free entry implies that if firms in an industry are earning excessively high profits,new firms that seek to do the same thing are likely to spring up.Fast food restaurants are quick to spring up when a new shopping center opens.Where profit opportunities present themselves, we assume that firms sill enter and compete for them.
Free exit is possible when firms can simply stop producing their products and leave a market .Generally speaking,a firm closes dowm because it is suffering losses or because profits are insufficient .New England textile and furniture products found themselves facing increasing foreign

competition, as well as lower production costs in the

South .While some firms packed up and moved ,others simply got out of the business altogether.
16. Which of the following is not a feature of perfect competition according to the passage?
A The firms involved are small compared to the size of the industry.
B The firms involved produce goods of the same kind .
C The size of the industry is ususlly very samll.
D The price of the products is deterimned by the market.
17. In a perfectly competitive industry ,the price is decided by
A some leading firms in this business.
B the rules of supply and demand.
C an association of the business.
D the central government.
18. If a firm sells its products at a price higher than that of the market ,consumers will
A buy goods of the same kind produced by other companies.
B stop buying this type of products altogether.
C use anlther type of goods as substitutes.
D continue to buy its products becausr of their good quality.
19. In the third paragraph,the author mentions"fast food restaurants"to show
A the rapid emergence of new industries in down town

areas.
B the prosperity of service indusries in backward countries .
C people"s enthusiasm for shopping .
D businessmen"s interest in high -profit industries.
20. What is the most important reason

for a company to quit a business?
A Some other firms are making more money .
B There is too much competition in this industry .
C It is not making adequate profit .
D Foreign products have got

control of the market.
