17．We already know the fastest，least expensive way to slow climate change：Use less energy．With a little effort，and not much money，most of us could reduce our energy diets by 25percent or more-doing the Earth a favor while also helping our wallets．
Not long age．My wife，PJ，and I tried a new diet-not to lose a little weight but to answer an annoying question about climate change．Scientists have reported recently that the world is bending up even faster than predicted only a few years ago，and that the consequences could be severe if we don't keep reducing emissions（排放）of carbon dioxide（CO2）and other greenhouse gases that are trapping heat in our atmosphere．
We decided to try an experiment．For one month we recorded our personal emissions of CO2..We wanted to see how much we could cut back，so we went on a strict diet．The average US household（家庭）produces about 150pounds of CO2a day by doing common-place things like turning on air-conditioning or driving cars．That's more than twice the European average and almost five times the global average，mostly because Americans drive more and have bigger houses．But how much should we try to reduce？
For an answer，I checked with Tim Flannery，author of The Weather Makers：How Man Is Changing the Climate and What It Means for Life on Earth．In his book，he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points，such as the melting（融化）of the ice sheets in Greenland or West Antarctica．"To stay below that point，we need to reduce CO2emissions by 80percent，"he said．
Good advice，I thought．I'd opened our bedroom windows to let in the wind．We'd gotten so used to keeping our air-conditioning going around the clock．I'd almost forgotten the windows even opened．We should not let this happen again．It's time for us to change our habits if necessary．

72．Why did the author and his wife try a new diet？B
A．To take special kinds of food

C．To lose weight
D．To improve their health

D．the average European household produces about 1，000pounds of CO2a month．

11．I know what you're thinking：pizza （比萨饼）？For breakfast？But the truth is that you can have last night's leftovers in the a．m．if you want to
     I know lots of women who skip breakfast （不吃早餐），and they have a ton of different excuses for doing it．Some say they don't have time．others think they're"saving"calories （卡路里），still others just don't like breakfast food．
     But the bottom line is that eating in the morning is very important when you're trying to lose weight．"Eating just about anything from 300to 400calories would be better than nothing at all，"says Katherine Brooking，R，D，who developed the super-easy eating plan for this year's"SELF CHALLENGE"．And even pizza can be healthy if it's loaded with vegetables，and you stick to one small piece．
     Breakfast is one meal I never miss，and the same goes for most weight loss success stories．Research shows that eating breakfast keeps you from overeating later in the day．Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal．
     So eat something in the morning，anything．I know plenty of friends who end up having no breakfast altogether，and have just coffee or orange juice．I say，try heating up last night's leftovers-it may sound crazy，but if it works for you，do it!I find if I tell myself，"You can always eat it tomorrow，"I put away the leftovers instead of eating more that night．Try it…you may save yourself some pre-bedtime calories．And watch your body gain the fat-burning effects．
