Years ago,a cigarette commercial asked if you were smoking more,but enjoying it less．That describes the way many of us live today．We are doing more,but enjoying it less．And when that doesn't work,we get the problem．In our extremely hurried search for satisfaction,we try stuffing still more into our days,never realizing that we are taking the wrong approach.The truth is simple;so simple it is hard to believe．Satisfaction lies with less,not with more．Yet,we pursue the myth that this thing,or that activity,will somehow provide the satisfaction we so desperately seek.Arthur Lindman,in his very effective book,"The Harried Leisure Class,"described the uselessness of pursuing more．His research focused on what people did with their leisure time．He found that as income rose,people bought more things to occupy their leisure time．But,ironically,the more things they bought,the less they valued any one of them．Carried to an extreme,he predicted massive boredom in the midst of tremendous variety．That was more than twenty years ago,and his prediction seems more accurate every year.Lindman of course,is not the first to discover this．The writer of Ecclesiastes expressed the same thought thousands of years ago．It is better,he wrote,to have less,but enjoy it more.If you would like to enjoy life more,I challenge you to experiment with me．How could you simplify your life?What could you drop?What could you do without?What could you stop pursuing?What few things could you concentrate on?The more I learn,the more I realize that fullness of life does not depend on things．The more I give up,the more I seem to gain．But words will never convince you．You must try it for yourself．The best title for the passage is__.A.Simplify Your LifeB.Enjoy Your LifeC.Smoking LessD.Satisfaction

共用题干第一篇Carbon FootprintHow often do you travel by plane?How much electricity do you use?These days everyone is worried about the size of their carbon footprint.In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?A new book might be able to help.The Carbon Footprint of Everything looks at the different things we do and buy,and calculates the amount of CO2 all of the following created:the ingredients, the electricity used in the brewery，the equipment,the travel and commuting of the beer,and the packaging. It's amazing how many different things need to be included in each calculation.And it's frightening how much carbon dioxide everything produces.But all of this can help us decide which beer to drink.From Berners-Lee's calculations,it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away,and it uses more packaging. The local beer only produces 300g of CO2,but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.Berners-Lee has even calculated the carbon footprint of cycling to work.Nothing is more environmentally-friendly than riding a bike,surely?Well,it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food.So if we eat a banana and then ride a kilometer and a half,our footprint is 65g of CO2.However,if we eat bacon before the bike ride,it's 200g. In fact,bananas are good in general because they don't need packaging,they can be transported by boat and they grow in natural sunlight.So,does this mean that cycling is bad for the environment?Absolutely not,for a start,if you cycle,you don't use your car,and the fewer cars on the road,the fewer traffic jams.And cars in traffic jams produce three times more CO2 than cars traveling at speed.Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!So maybe it's time for us all to start making some changes.Pass me a banana and a pint of local beer,please.To make our carbon footprints smaller,we should often________.A:cycle to workB:drink more local beerC:calculate the amount of CO2D:buy cheap things from the supermarkets

Research Is a State of Mind For many years there has been much misunderstanding as to just what research is. The popular conception seems to be that there is something mysterious about it， and before any research can be done it is necessary to have expensive scientific apparatus and large， elaborately equipped laboratories. Actually， this is not so. （6） It is a simple， organized way of trying to accomplish something you wish to do—so simple that anyone can do research anywhere at any time. First， you select the problem you would like to solve， then you list at least ten reasons why it has not been solved. （7） It takes just as much effort to solve a useless problem as a useful one. （8） After carefully—and I want to emphasize that word “carefully”—selecting the problem and the ten things between you and the solution， you then use the same procedure as in solving a crossword puzzle.（9）In the solution of the remaining obstacles you may need some simple apparatus， but the things you will probably need most are infinite patience and persistence. Few people realize the difficulties of doing any new thing. Maybe one of the reasons people are so easily discouraged is because of their education. During all our years at school we were examined two or three times a year. If we failed once， we were out. （10）If we are going to make progress， we must learn to fail intelligently so that we won't become discouraged at the 99.9 per cent failure.9.（）A、Make sure the game is worth the candle.B、That is a step in the right direction， but I don't believe it is enough.C、You take the easy obstacles first and by a process of elimination you eventually arrive at the one or two major ones.D、But in selecting the problem， you need to be sure to analyze it carefully to see that it is worth the effort.E、Research isn't a physical thing at all； it's a state of mind.F、By contrast， all research work is 99. 9 per cent failure and， if we succeed once， we are in.
