unit 17 b卷一、阅读理解aa man living absolutely alone in a desert or forest is free from other people，but he is not absolutely free.his freedom is limited in several ways.firstly，by the things around him，such as wild animals or cliffs.secondly，by his own needs：he must have sleep，water，food and shelter from extreme heat or cold.lastly，by his own nature as a man：disease may attack him，and death will certainly come to him sooner or later.on the other hand，when men become organized into very large groups and civilization develops，it is possible to get freedom from hunger，thirst，cold，heat，and many diseases，so that each person can live a happier life than he could if he were living alone；but such a society cannot work successfully unless the freedom of each human being is to some extent limited so that he is kept from hurting others.i am not free to kill others，nor to steal someone elses property，nor to act in a way that does wrong against the moral sense of the society in which we live.i have to limit my own freedom myself so that others will not limit it too much.i agree to respect the rights of others，and in return they agree to respect mine.the advantages of such an agreement are great.one can become a doctor knowing that others will grow food，make clothes and build a house for him，in return for the work he does to keep them healthy.if each man had to grow his own food，make his own clothes，build his own house and learn to be his own doctor，he would find it impossible to do any one of these jobs really well.by working together，we make it possible for society to provide us all with food，clothes，shelter and medical care，while leaving each of us with as much freedom as it can.1a man living alone in a desert or forest _.ais absolutely freebfeels happychas limited freedom

have themare made of a form of plastic that is very slow to break down in the environment.a typical cigarette butt can take from 18 months to 10 years to decompose，depending on environmental conditions.besides the plastic，these filterswhich are on cigarettes in the first place to absorb pollutants to prevent them from going into the lungscontain poisons.thus when smokers throw away their butts improperlyout of car windows or onto the sidewalksthey are essentially throwing these poisonous substances into the environment.while any individual thrownaway cigarette butts may be small，the butts add up to a huge problem.some 5.5 trillion cigarettes are consumed worldwide each year.cigarette butts make up as much as onethird of all litter nationwide when measured by the number of discarded items，not the total volume.while the tobacco industry may have its hands full just trying to stay afloat in the maelstrom(旋涡)of ongoing bad publicity，critics say it should be doing more to prevent butt litter.“just as beverage manufacturers contribute to antilittering campaigns，and have invested in public education on litter issues，so should the tobacco industry，”says kathleen register，a researcher.register suggests putting antilittering messages on all cigarette packaging and advertisements，distributing small，free portable ashtrays(烟灰缸)，and placing and maintaining outdoor ashtrays in areas where smokers gather.she also suggests putting an extra tax on cigarette sales，with the money going toward antilittering education and paying the costs of cleaning up butts.“by taxing smokers for such efforts，some of the cost of cleaning up cigarette butts will shift onto them，”she says.one way or another，smokers must learn that the earth is not one giant ashtray.5the
