Until¡¡the¡¡twentieth¡¡century¡¡cigarettes¡¡were¡¡not¡¡an¡¡important¡¡threat¡¡(Íþв)¡¡to¡¡public¡¡health.¡¡Men¡¡used¡¡tobacco¡¡mainly¡¡in¡¡the¡¡form¡¡of¡¡cigars¡¡(Ñ©ÇÑÑÌ),¡¡chewing¡¡tobacco,¡¡pipe¡¡tobacco(Ñ̲Ý),¡¡and¡¡snuff¡¡(±ÇÑÌ).¡¡Most¡¡women¡¡did¡¡not¡¡use¡¡tobacco¡¡at¡¡all.
The¡¡cigarette¡¡industry¡¡began¡¡in¡¡the¡¡1870s¡¡with¡¡the¡¡development¡¡of¡¡the¡¡cigarette¡¡manufacturing¡¡machines.¡¡This¡¡made¡¡it¡¡possible¡¡to¡¡produce¡¡great¡¡numbers¡¡of¡¡cigarettes¡¡very¡¡quickly,¡¡and¡¡it¡¡reduced¡¡the¡¡price.
Today¡¡cigarettes¡¡smoking¡¡is¡¡a¡¡widespread¡¡habit.¡¡About¡¡forty-three¡¡percent¡¡of¡¡the¡¡adult¡¡men¡¡and¡¡thirty-one¡¡percent¡¡of¡¡the¡¡adult¡¡women¡¡in¡¡the¡¡United¡¡States¡¡smoke¡¡cigarettes¡¡regularly.¡¡It¡¡is¡¡encouraging¡¡to¡¡note,¡¡however,¡¡that¡¡millions¡¡of¡¡people¡¡have¡¡given¡¡up¡¡the¡¡smoking¡¡habit.¡¡Seventy-five¡¡percent¡¡of¡¡the¡¡male¡¡population¡¡and¡¡forty-six¡¡percent¡¡of¡¡the¡¡these¡¡men¡¡and¡¡eleven¡¡percent¡¡of¡¡the¡¡women¡¡have¡¡stopped¡¡smoking.¡¡The¡¡number¡¡of¡¡persons¡¡who¡¡have¡¡given¡¡up¡¡smoking¡¡is¡¡increasing.
Men¡¡as¡¡a¡¡group¡¡smoke¡¡more¡¡than¡¡women.¡¡Among¡¡both¡¡men¡¡and¡¡women¡¡the¡¡age¡¡group¡¡with¡¡the¡¡highest¡¡proportion¡¡(±ÈÀý)¡¡of¡¡smokers¡¡is¡¡the¡¡age¡¡group¡¡24-44.
Income,¡¡education,¡¡and¡¡occupation¡¡all¡¡play¡¡a¡¡part¡¡in¡¡determining¡¡a¡¡person's¡¡smoking¡¡habits.¡¡City¡¡people¡¡smoke¡¡more¡¡than¡¡people¡¡living¡¡on¡¡farms.¡¡Well-educated¡¡men¡¡with¡¡high¡¡incomes¡¡are¡¡less¡¡likely¡¡to¡¡smoke¡¡cigarettes¡¡than¡¡men¡¡with¡¡fewer¡¡years¡¡of¡¡schooling¡¡and¡¡lower¡¡incomes.¡¡On¡¡the¡¡other¡¡hand¡¡if¡¡a¡¡well-educated¡¡man¡¡with¡¡a¡¡high¡¡income¡¡smokes¡¡as¡¡all,¡¡he¡¡is¡¡likely¡¡to¡¡smoke¡¡more¡¡packs¡¡of¡¡cigarettes¡¡per¡¡day.
The¡¡situation¡¡is¡¡somewhat¡¡different¡¡for¡¡women.¡¡There¡¡are¡¡slightly¡¡more¡¡smokers¡¡among¡¡women¡¡with¡¡higher¡¡family¡¡incomes¡¡and¡¡higher¡¡education¡¡than¡¡among¡¡the¡¡lower¡¡income¡¡and¡¡lower¡¡educational¡¡groups.¡¡These¡¡more¡¡highly¡¡educated¡¡women¡¡tend¡¡to¡¡smoke¡¡more¡¡heavily.
Among¡¡teenagers¡¡(ÉÙÄê)¡¡the¡¡pictures¡¡is¡¡similar.¡¡There¡¡are¡¡fewer¡¡teenager¡¡smokers¡¡from¡¡upper-income,¡¡well-educated¡¡families¡¡and¡¡fewer¡¡from¡¡families¡¡living¡¡in¡¡farm¡¡areas.¡¡High¡¡school¡¡students¡¡who¡¡are¡¡preparing¡¡for¡¡college¡¡are¡¡less¡¡likely¡¡to¡¡smoke¡¡than¡¡those¡¡who¡¡do¡¡not¡¡plan¡¡to¡¡continue¡¡their¡¡education¡¡after¡¡high¡¡school.¡¡Children¡¡are¡¡most¡¡likely¡¡to¡¡start¡¡smoking,¡¡if¡¡one¡¡or¡¡both¡¡of¡¡their¡¡parents¡¡smoke.

Passage¡¡2
Many¡¡of¡¡us¡¡believe¡¡that¡¡a¡¡person's¡¡mind¡¡becomes¡¡less¡¡active¡¡as¡¡he¡¡grows¡¡older.¡¡But¡¡this¡¡is¡¡not¡¡true,¡¡according¡¡to¡¡Dr.¡¡Jarvik,¡¡professor¡¡of¡¡psychiatry¡¡(¾«Éñ²¡Ñ§)¡¡at¡¡the¡¡University¡¡of¡¡California.¡¡She¡¡has¡¡studied¡¡the¡¡mental¡¡functioning¡¡of¡¡aging¡¡persons¡¡for¡¡several¡¡years.¡¡For¡¡example,¡¡one¡¡of¡¡her¡¡studies¡¡concerns¡¡136¡¡pairs¡¡of¡¡identical¡¡twins¡¡(ÂÏÉú¶ù),¡¡who¡¡were¡¡first¡¡examined¡¡when¡¡they¡¡were¡¡already¡¡60¡¡years¡¡old.¡¡As¡¡Dr.¡¡Jarvik¡¡continued¡¡the¡¡study¡¡of¡¡the¡¡twins¡¡into¡¡their¡¡70s¡¡and¡¡80s,¡¡their¡¡minds¡¡did¡¡not¡¡generally¡¡decline¡¡as¡¡was¡¡expected.
However,¡¡there¡¡was¡¡some¡¡decline¡¡in¡¡their¡¡psycho-motor¡¡speed.¡¡This¡¡means¡¡that¡¡it¡¡took¡¡them¡¡longer¡¡to¡¡accomplish¡¡mental¡¡tasks¡¡than¡¡it¡¡used¡¡to.¡¡But¡¡when¡¡speed¡¡was¡¡not¡¡a¡¡factor,¡¡they¡¡lost¡¡very¡¡little¡¡intellectual¡¡ability¡¡over¡¡the¡¡years.¡¡In¡¡general,¡¡Dr.¡¡Jarvik's¡¡studies¡¡have¡¡shown¡¡that¡¡there¡¡is¡¡no¡¡decline¡¡in¡¡knowledge¡¡or¡¡reasoning¡¡ability.¡¡This¡¡is¡¡true¡¡not¡¡only¡¡with¡¡those¡¡in¡¡their¡¡30s¡¡and¡¡40s,¡¡but¡¡with¡¡those¡¡in¡¡their¡¡60s¡¡and¡¡70s¡¡as¡¡well.
It¡¡is¡¡true¡¡older¡¡people¡¡themselves¡¡often¡¡complain¡¡that¡¡their¡¡memory¡¡is¡¡not¡¡as¡¡good¡¡as¡¡it¡¡once¡¡was.¡¡However,¡¡much¡¡of¡¡what¡¡we¡¡call¡¡'loss¡¡of¡¡memory'¡¡is¡¡not¡¡that¡¡at¡¡all.¡¡There¡¡was¡¡usually¡¡incomplete¡¡learning¡¡in¡¡the¡¡first¡¡place.¡¡For¡¡example,¡¡the¡¡older¡¡person¡¡perhaps¡¡had¡¡trouble¡¡hearing,¡¡or¡¡poor¡¡vision,¡¡or¡¡inattention,¡¡or¡¡was¡¡trying¡¡to¡¡learn¡¡the¡¡new¡¡thing¡¡at¡¡too¡¡fast¡¡a¡¡pace.¡¡In¡¡the¡¡cases¡¡where¡¡the¡¡older¡¡person's¡¡mind¡¡really¡¡seems¡¡to¡¡become¡¡less¡¡active,¡¡it¡¡is¡¡not¡¡necessarily¡¡a¡¡sign¡¡of¡¡becoming¡¡less¡¡active¡¡due¡¡to¡¡old¡¡age.¡¡Often¡¡it¡¡is¡¡simply¡¡a¡¡sign¡¡of¡¡a¡¡depressed¡¡emotional¡¡(ѹÒֵĸÐÇé)¡¡state.¡¡
6.¡¡According¡¡to¡¡Dr.¡¡Jarvik's¡¡studies,¡¡middle-aged¡¡and¡¡older¡¡persons¡¡would¡¡expect¡¡to¡¡__________.

Passage¡¡3
For¡¡hundreds¡¡of¡¡years,¡¡diseases¡¡caused¡¡by¡¡lack¡¡in¡¡nutrition¡¡(ÓªÑø)¡¡were¡¡known¡¡to¡¡men.¡¡Some¡¡common¡¡nutritional¡¡diseases¡¡are¡¡beriberi¡¡(½ÅÆø),¡¡and¡¡scurvy¡¡(»µÑª²¡).¡¡In¡¡the¡¡18th¡¡century,¡¡James¡¡Lind,¡¡a¡¡Scottish¡¡doctor,¡¡discovered¡¡a¡¡cure¡¡beriberi¡¡-¡¡whole¡¡rice.
A¡¡British¡¡scientist¡¡in¡¡1906¡¡showed¡¡that¡¡certain¡¡foods¡¡contain¡¡substances¡¡important¡¡to¡¡the¡¡growth¡¡and¡¡development¡¡of¡¡the¡¡body.¡¡In¡¡time¡¡these¡¡substances¡¡were¡¡called¡¡vitamins,¡¡meaning¡¡essential¡¡to¡¡life.¡¡Today¡¡there¡¡are¡¡13¡¡known¡¡vitamins.¡¡The¡¡human¡¡body¡¡produces¡¡only¡¡three¡¡of¡¡them.
Vitamins¡¡regulate¡¡(µ÷½Ú)¡¡the¡¡way¡¡the¡¡body¡¡changes¡¡food¡¡into¡¡energy¡¡and¡¡living¡¡tissues¡¡(×éÖ¯).¡¡Each¡¡vitamins¡¡has¡¡a¡¡definite¡¡use¡¡and¡¡the¡¡lack¡¡of¡¡one¡¡vitamin¡¡can¡¡interfere¡¡with¡¡the¡¡function¡¡of¡¡another.¡¡The¡¡continued¡¡lack¡¡of¡¡one¡¡vitamin¡¡can¡¡cause¡¡a¡¡vitamin¡¡lack¡¡disease.
The¡¡best¡¡way¡¡for¡¡a¡¡healthy¡¡person¡¡to¡¡get¡¡vitamins¡¡is¡¡to¡¡eat¡¡a¡¡balanced¡¡diet.¡¡Eggs,¡¡milk,¡¡meat,¡¡vegetables,¡¡fruits,¡¡and¡¡whole¡¡-¡¡grain¡¡are¡¡the¡¡most¡¡common¡¡sources¡¡of¡¡the¡¡necessary¡¡variety¡¡of¡¡foods.
Vitamins¡¡help¡¡to¡¡speed¡¡up¡¡certain¡¡chemical¡¡reactions¡¡in¡¡the¡¡body.¡¡These¡¡reactions¡¡are¡¡essential¡¡for¡¡health.¡¡Without¡¡vitamins,¡¡these¡¡reactions¡¡would¡¡occur¡¡very¡¡slowly¡¡or¡¡not¡¡at¡¡all.
Truly¡¡vitamins¡¡have¡¡been¡¡correctly¡¡named¡¡-¡¡essential¡¡to¡¡good¡¡health¡¡and¡¡life.

Some¡¡psychologists¡¡(ÐÄÀíѧ¼Ò)¡¡maintain¡¡that¡¡mental¡¡acts¡¡such¡¡as¡¡thinking¡¡are¡¡not¡¡performed¡¡in¡¡the¡¡brain¡¡alone,¡¡but¡¡that¡¡one's¡¡muscles¡¡also¡¡participate¡¡(²Î¼Ó).¡¡It¡¡may¡¡be¡¡said¡¡that¡¡we¡¡think¡¡with¡¡our¡¡muscles¡¡in¡¡somewhat¡¡the¡¡same¡¡way¡¡that¡¡we¡¡listen¡¡to¡¡music¡¡without¡¡bodies.
You¡¡surely¡¡are¡¡not¡¡surprised¡¡to¡¡be¡¡told¡¡that¡¡to¡¡music¡¡not¡¡only¡¡with¡¡your¡¡ears¡¡but¡¡with¡¡your¡¡whole¡¡body.¡¡Few¡¡people¡¡can¡¡listen¡¡to¡¡music¡¡that¡¡is¡¡more¡¡or¡¡less¡¡familiar¡¡without¡¡moving¡¡their¡¡body¡¡or¡¡more¡¡specifically¡¡(¾ßÌ嵨),¡¡some¡¡part¡¡of¡¡their¡¡body.¡¡Often¡¡when¡¡one¡¡listens¡¡to¡¡a¡¡concert¡¡on¡¡the¡¡radio,¡¡he¡¡is¡¡tempted¡¡to¡¡direct¡¡the¡¡orchestra¡¡(¹ÜÏÒÀÖ¶Ó)¡¡even¡¡though¡¡knows¡¡where¡¡to¡¡direct¡¡the¡¡orchestra¡¡even¡¡though¡¡he¡¡knows¡¡there¡¡is¡¡an¡¡able¡¡conductor¡¡on¡¡the¡¡job.

For¡¡those¡¡who¡¡do¡¡not¡¡particularly¡¡enjoy¡¡competitive¡¡(¾ºÕùÐÔµÄ)¡¡sports,¡¡it¡¡is¡¡especially¡¡difficult¡¡to¡¡do¡¡so¡¡if¡¡you¡¡are¡¡not¡¡good¡¡at¡¡them.¡¡There¡¡are¡¡such¡¡activities¡¡for¡¡one¡¡person¡¡as¡¡cycling,¡¡walking¡¡and¡¡swimming.¡¡What¡¡often¡¡happens,¡¡though,¡¡is¡¡that¡¡you¡¡do¡¡them¡¡in¡¡such¡¡a¡¡leisurely¡¡way,¡¡so¡¡slowly,¡¡that¡¡it¡¡is¡¡doubtful¡¡if¡¡you¡¡are¡¡doing¡¡yourself¡¡much¡¡good,¡¡apart¡¡from¡¡the¡¡fact¡¡that¡¡you¡¡have¡¡at¡¡least¡¡managed¡¡to¡¡get¡¡up¡¡out¡¡of¡¡your¡¡armchair.¡¡Of¡¡course¡¡you¡¡can¡¡be¡¡very¡¡thorough¡¡about¡¡exercise.¡¡Many¡¡sports¡¡shops¡¡now¡¡sell¡¡frightening¡¡pieces¡¡of¡¡apparatus,¡¡chest-expanders¡¡and¡¡other¡¡mysterious¡¡gadgets¡¡(СװÖÃ)¡¡of¡¡shiny¡¡spring¡¡steel,¡¡which,¡¡according¡¡to¡¡the¡¡advertisements,¡¡will¡¡bring¡¡you¡¡up¡¡to¡¡an¡¡Olympic¡¡standard¡¡of¡¡fitness,¡¡provided¡¡that¡¡you¡¡follow¡¡a¡¡regular¡¡programme¡¡of¡¡exercises.¡¡Such¡¡programmes¡¡generally¡¡involve¡¡long¡¡periods¡¡of¡¡time¡¡bending¡¡these¡¡curious¡¡bits¡¡of¡¡metal¡¡into¡¡improbable¡¡shapes.
