People have speculated for centuries about a future without work.Today is no different,with academics,writers,and activists once again 1 that technology is replacing human workers.Some imagine that the coming work-free world will be defined by 2.:A few wealthy people will own all the capital,and the masses will struggle in an impoverished wasteland..A different and not mutually exclusive 3 holds that the future will be a wasteland of a different sort,one 4 by purposelessness:Without jobs to give their lives 5,people will simply become lazy and depressed.6,today’s unemployed don’t seem to be having a great time.One Gallup poll found that 20 percent of Americans who have been unemployed for at least a year report having depression,double the rate for 7 Americans.Also,some research suggests that the 8 for rising rates of mortality,mental-health problems,and addicting 9 poorly-educated,middle-aged people is a shortage of well-paid jobs.Perhaps this is why many 10 the agonizing dullness of a jobless future.But it doesn’t 11 follow from findings like these that a world without work would be filled with unease.Such visions are based on the 12 of being unemployed in a society built on the concept of employment.In the 13 of work,a society designed with other ends in mind could 14 strikingly different circumstances for the future of labor and leisure.Today,the 15 of work may be a bit overblown.“Many jobs are boring,degrading,unhealthy,and a waste of human potential,”says John Danaher,a lecturer at the National University of Ireland in Galway.These days,because leisure time is relatively 16 for most workers,people use their free time to counterbalance the intellectual and emotional 17 of their jobs.“When I come home from a hard day’s work,I often feel 18,”Danaher says,adding,“In a world in which I don’t have to work,I might feel rather different”—perhaps different enough to throw himself 19 a hobby or a passion project with the intensity usually reserved for 20 matters.16选?A.trickyB.lengthyC.mysteriousD.scarce

共用题干第三篇Weaving with LightIn the Sierra Madre mountain range of west central Mexico,the native Huichol people live much the way their ancestors did一without electricity,That’s because it's too expensive to string power lines to the remote mountain areas where they live.To help support themselves,the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages.And without electricity一at home or on the road,they can only work during daylight hours?When it gets dark,they must stop whatever they'redoing.Now,a team of scientists,designers,and architects is using new technologies to provide the Huichol with light after the sun sets.The scientists'technique involves weaving tiny electronic crystals into fabrics that can be made into clothes,bags,or other items.By collecting the sun’s energy during the day,these lightweight fabrics provide bright white light atnight一 Their inventors have named the fabrics" Portable(轻便的)Lights."Portable Lights have the potential to transform the lives of people without electricity around the world.At the core of Portable Lights technology are devices called high-brightness light-emitting diodes(高亮 度发光二极管),or HB LEDs. These tiny lights appear in digital clocks, televisions, and streetlights.LEDs are completely different from the light bulbs(灯泡).Most of those glass bulbs belong to a type called incandescent lights(白炽灯).Inside, electricity heats a metal coil(线圈)to about 2. 200 degrees Celsius.At that temperature,bulbs give off light we can see.Ninety percent of energy produced by mnean- descent lights,however,is heat一and invisible.With all that wasted energy,bulbs burn out quickly. Theyare also easily broken.LEDs,on the other hand,are like tiny pieces of rock made up of molecules(分子)that are arranged in a crystal structure.When an electric current passes through a LED,the crystal structure produces light. Un- like incandescent bulbs,they can produce light of various colors.Within a LED,the type of molecules and their particular arrangement determine what color is produced.LEDs are different from light bulbs in that__________.A:LEDg are made up of tiny pieces of rockB:LEDs can send out light of different colorsC:LEDs belong to incandescent lightsD:LEDs look like crystals
