问题     What do dieting and energy policy have in common? The SnackWell effect. The name comes from those tasty little cookies that are【S1】______as being lower in fat and sugar. But they often lead dieters to eat more of them than【S2】______cookies and then wonder why they’re not losing weight.
    It turns out there’s a SnackWell effect for energy use too—and it may make it tougher for us to cut back on carbon. When【S3】______conscious consumers buy an energy-efficient dishwasher, for example, they may feel less guilty about【S4】______the machine more often and as a result may not end up saving much on their utility bills. Likewise, studies indicate that people who【S5】______more-energy-efficient lights lose 5% to 12% of the expected savings by leaving them on longer.
    Much like dieters eating too many SnackWell’s, we can fail in our attempts to save energy and money. So resist the【S6】______to raise your thermostat(恒温器)after you buy a more efficient furnace; lower the temperature by a degree and shave another 1% off your heating bill.
    But even if we do what Jimmy Carter did and wear a 70s-style sweater all winter, we may end up spending those energy savings somewhere else—like on a plane【S7】______to Bermuda. A report estimated that【S8】______, this effect could reduce the savings from energy efficiency by 10% or more.
    That doesn’t mean energy-efficiency measures are【S9】______—or that we should never go on vacation. But it does mean that cutting back on energy【S10】______, like dieting, is not an excuse to stuff ourselves on less guilty pleasures.
A)ride B)urge C)saving D)special
E)regular F)advertised G)install H)environmentally
I)globally J)route K)acting L)running
M)consumption N)operated O)useless [br] 【S9】
选项
答案 O
解析 此处需填入形容词。从doesn’t mean可知此处并非像上文一样一味否定节能措施的作用，useless跟doesn’t一起为双重否定，表肯定，选useless。
