you hear that fluffy died？”
19。 With Mars the scientific stakes are arguably higher than they have ever been。 The issue of whether life ever existed on the planet； and whether it persists to this day； has been highlighted by mounting evidence that the Red Planet once had abundant stable； liquid water and by the continuing controversy over suggestions the bacterial fossils rode to Earth on a meteorite from Mars。 A more conclusive answer about life on Mars； past or present； would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life。
20。 Music resources on the Internet isn’t a flashy Web site； it is just five or six pages of text with links。 But with a total of nearly 2；000 links； it is a very good place to start your search for musical information on the Web。 Music Resources focuses primarily on Western classical music； but the site has something for almost everyone： fan pages for bands you have never heard of （and for bands you love）； record company web sites； scholarly papers； cool instruments from all over the world； discographies of your favorite jazz musicians。 If they’d only add a search engine Music Resources on the Internet would be just about perfect。 Access to Music Resources on the Internet： http： //music。indiana。edu/musicresources/
21。 Although their missions blended commercial and politicalmilitary imperatives； the explorers involved all accomplished some significant science by going where no scientists had gone before。 Today Mars looms as humanity’s next great terra incognito。 And with doubtful prospects for a shortterm financial return； with the cold war rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures； it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet’s reddish surface。
22。 In April 1995； the United States； Britain； the Soviet Union and France held a summit conference in Geneva。 The question of nuclear weapons inspection was an important item on the agenda。 The US； Britain and France adopted a common stand； agreeing to certain stipulations on inspection of nuclear weapons； but the Soviet Union made it clear that they were opposed to stipulations of any sort on nuclear weapons inspection； regarding them as virtually a violation of their sovereignty and therefore totally unacceptable。
23。 Marketing； on the other hand； focuses on the wants of consumers。 It begins with first analyzing the preferences and demands of consumers and then producing goods that will satisfy them。 This eyeontheconsumer approach is known as the marketing concept； which simply means that instead of trying to sell whatever is easiest to produce or buy for resale； the makers and dealers first endeavor to find out what the consumer wants to buy and then go about making it available for purchase。
24。 Life went on。 Ground was broken for the new house on a blueandgold day in December。 The quads were old enough to stand； and each was given a little gilded shovel to mark the occasion。 Many friends and neighbors were there； and the mayor of Swainsboro put our feelings into words： “We hope that when these babies are grown； they will look at this house and understand how much their father was respected and admired by everyone who knew him。”
25。 In fact； society exploits our emotional reactions and attitudes； such as loyalty； morality； pride； shame； guilt； fear and greed； in order to maintain itself。 It gives high rewards to individuals who perform important tasks such as surgery； makes heroes out of individuals for unusual or dangerous achievements such as flying fighter planes in a war； and uses the legal and penal system to make people afraid to engage in antisocial acts。
26。 Originally this vast area lying to the west of Place de la Concorde was swamp land。 After its proclamation； in 1667 it was turned into a wide avenue called GrandCours； reaching from the Tuileries as far as Place de Gaulle。 At the beginning of the avenue are the horses of Marly； from this point as far as the Ronde Point of the Champs Elysees the avenue is flanked by a park。 At the time of the Second Empire； this became the most fashionable meetingplace and upperclass residential area in all Paris。 Today it may no longer have its onetime aristocratic character； but it has lost nothing of its beauty and elegance； luxurious shops； theatres； famous restaurants and important airline offices line its wide footpaths； which are always full of Parisians； tourists and a cosmopolitan throng。
27。 True； we consider the length； shape； size； or texture； but an object’s physical aspects are less important than what it has done or can do to us —— hurt us； surprise us； anger us or make us joyful。 We also use categorizations colored by emotions in our families； communities； and overall society。 Out of our emotional experiences with objects and events comes a social feeling of agreement that certain things and actions are “good” and others are “bad”； and we apply these categories to every aspect of our social life —— from what foods we eat and what clothes we wear to how we keep promises and which people our group will accept。
28。 Because the changes in world climate will be rapid； natural ecosystems —— wetlands； rain forests； savannas —— may be unable to adapt。 Animals and plants that have evolved to live under a certain set of climate conditions will suddenly face different circumstances。 Many will go extinct。 And the potential for deadly disease outbreaks will rise： warming waters will be more hospitable to germs like those that cause cholera； disease carriers such as the Aedes aegypti mosquito may find they can survive nicely in places like northern Europe and the U。S。； making illnesses such as malaria more widespread。
29。 It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact： if they are not looking； the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will terminate the conversation。 Just how critical this eye maneuvering is to the maintenance of conversational flow becomes evident when two speakers are wearing dark glasses： there may be a sort of traffic jam of words caused by interruption； false starts； and unpredictable pauses。
30。 The good news is that this gloomy scenario may galvanize the world’s governments into taking serious action。 The first line of attack； says Florentin Krause； an IPCC contributor and director of the California —— based International Project for Sustainable Energy Paths； should be “no regrets” actions —— changes that will be beneficial no matter how much of a threat global warming turns out to be。 Among them： promoting the use of energy efficient appliances and cars。
31。 A study of drugstore and supermarket shelves will convince any observer that all possible sizes and shapes of boxes； jars； bottles； and tins are in use at the same time； and； as the package journals show； week by week； there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation。 The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes； but no one in the trade comments unfavorably on the huge costs incurred by endless changes of package sizes； materials； shape； art work； and net weights that are used for improving a product’s market position。
32。 No one much likes the idea of thawing out one of the clone kids to harvest its organs； but according to Andrew Kimbrell； author of The Human Body Shop； in the past few years an estimated 50 to 100 couples have produced babies to provide tissue for an existing child。 Plus there is already a thriving market in Third World kidneys and eyes。 Is growing your own really so much worse than plundering the bodies of the poor？ Or maybe we’ll just clone for the fun of it。 If you like a movie scene； you can rewind the tape； so when Junior II？ Sooner or later； am
