　　A Strange Flight
　　We were late as usual. My husband had insisted on watering the flowers in the garden by himself， and when he discovered that he couldn‘t manage， he asked me for help at the last moment. So now we had an hour to get to the airport. Luckily， there were not many cars or buses on the road and we were able to get there just in time. We checked in and went straight to a big hall to wait for flight to be called. We waited and waited， but no announcement was made. We asked for information and the girl there told us that the plane hadn’t even arrived yet. In the end， there was another announcement telling us that passengers waiting for Flight LJ108 could get a free meal voucher² （凭单） and that the plane hadn‘t left Spain for technical problems. We thought that meant that if wasn’t safe for the plane to fly. We waited again for a long time until late evening when we were asked to report again. This time we were given vouchers³ to spend the night in a nearby hotel.
　　The next morning after a bad night because of all the planes taking off and landing， we were reported back to the airport. Guess what had happened while we were asleep！ Our plane had arrived and taken off again. All the other passengers had been forgotten. You can imagine how we felt！

　　Hair Care
　　Whether the hair is long or short， it must be regularly brushed （梳）and regularly washed. For greasy⁴ （油性的） hair， especially if the owner lives in a town， it may be necessary to wash the head every four to five days. Those with a dry hair can usually go a little longer， but this is a matter for the individual to decide.
　　If a woman is not able to go to hairdresser very often， it is important that she chooses a style she can easily manage for herself， and this nearly always means that the first cut must be very standard. The same applies to permanent （永久的）waving. I delay， this should be carried out three or four times a year， so that the hair never gets out of hand.
　　One thing would be remembered though， that is， whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care. Or you may use milder products. As for style， this must be studied according to what is the latest fashion and also to suit the individual at different times of her life.
　　Young people who has spots or skin troubles on their face， should take particular care to ensure that the hair is both clean and does not come into contact with the affected⁵ piece of skin. Hair is very difficult to keep completely clean and therefore anyone running their hands through their hair and afterwards touching⁶ their face， or letting their hair fall over their faces， might spread infection from one place to another. Good hair does a lot to the effect of a face， so if you want to look charming， please start with your hair.
　　6. According to the text， the most basic thing to do in hair care is
　　A to go to hairdressers very often B to choose milder products for the hair.

　　The Gene⁷ Industry
　　Major companies are already in pursuit of commercial applications of the new biology .They dream of placing nxymse（酶）in the automobile⁸ to monitor exhaust nad send data om pollution to a microprocessor⁹ 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 rivalry¹⁰ 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 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 ，thereby¹¹ 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 monotonous¹² work for us ？Should we attempt to eliminate“inferior”people and breed a “super-race”？（Hitler tried this ，but without the genetic¹³ 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 “savings¹⁴ 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 Ted¹ 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 ，automobiles¹⁵，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

　　Perfect Competition
　　Perfect competition exists in an industry that contains many relatively²⁰ samll firms producing identical products.The most importhant characteristic（特征） of a perfectly²¹ 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 differentiate²²（区分） their products， nor do they make decisions about price.Rather，each firm takes prices as given-that is ，as determined²³ 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 insufficient²⁴ .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.

　　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 emergence²⁶ of new industries in down town areas.
