[单项选择]The night is not what it was. Once, the earth was cast half in shadow. Then came fire, candle, and light bulb, gradually drawing back the curtain of darkness. But a brighter world has its drawbacks. An estimated 30 percent of outdoor lighting—plus even some indoor lighting—is wasted.

Scientists say they have achieved small-scale nuclear fusion in a tabletop experiment, using tried and true techniques that are expected to generate far less controversy than past such claims.
This latest experiment relied on a tiny crystal to generate a strong electric field. While the energy created was too small to harness cheap fusion power, the technique could have potential uses in medicine, spacecraft propulsion, the oil drilling industry and homeland security, said Seth Putterman, a physicist at the University of California at Los Angeles.
Putterman and his colleagues at UCLA, Brian Naranjo and Jim Gimzewski, report their results in Thursday’s issue of the journal Nature.

Passage Two
Parents have to do much less for their children than they used to do, and home has become much less of a workshop. Clothes can be bought ready made; washing can be done at the laundry; food can be bought cooked, canned; bread is baked and delivered by the baker; milk arrives on the doorstep; meal can be had at the restaurant, the work’s canteen, and the school dining room.
It’s unusual now for father to persue(追求)his trade of other employment at home, and his children rarely, if ever, see him at his place of work. Boys are therefore seldom trained to follow their father’s business, and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon gains a feeling of economic independence (经济上的独立). In textile areas it has been customary for mothers to go out to work, but this practice has become so widespread that the working mother is now not an unusual
