how our understanding of the world has grown from 1900 to today.Before ReadingGlobal ReadingDetailed ReadingAfter ReadingHome第2页1900:MATTERS OF LIFE AND DEATH-Medicine and HealthToday:BR_warm_Journey-MATTERS-Before ReadingGlobal ReadingDetailed ReadingAfter ReadingHomePatients battle illness,while doctors can do little more than counsel（劝说）and comfort them and keep them clean.Doctors treat and often cure patients with a vast array(一大批)of medicines and medical technologies,but some diseases are still incurable.第3页1900:MYSTERIES OF THE UNIVERSE-Physics and Astronomy Today:BR_warm_Journey-MYSTERIESBefore ReadingGlobal ReadingDetailed ReadingAfter ReadingHomeThe Milky Way galaxy（星系）(including some unexplained nebular clouds（星云）)is the known universe.Newtons laws explain the physical world.Matter is composed of atoms.The Milky Way is just one galaxy among countless millions we have observed in the universe.There is no set of laws that explains all phenomena in the physical world,although there are many theories.Atoms are composed of many subatomic particles,all of which derive from（来自于)energy.第4页1900:Today:BR_warm_Journey-RESEARCHRESEARCH INTO OURSELVES-Human BehaviorBefore ReadingGlobal ReadingDetailed ReadingAfter ReadingHomeMental illness can be treated with a range of therapies(治疗)and medications.We know a great deal about the chemistry and the parts of the brain that control our behavior and thoughts.There is no cure for the mentally ill,who are confined to insane asylums(精神病院).“Mind”and“body”arethought of as two separate things.第5页1900:The only way to view the Olympic Games in Paris is in person.News about the Games travels to America via（经过）telegraph and is printed in newspapers.Today:BR_warm_Journey-FCBFASTER,CLOSER,BETTER-TechnologyBefore ReadingGlobal ReadingDetailed ReadingAfter ReadingHomeMillions worldwide will watch the Beijing Olympics on television,transmitted instantaneously(瞬间地)by satellite.The news will spread as well by radio,newspaper,and the World Wide Web.第6页1900:There is no good explanation for catastrophic events such as earthquakes.The Earth is thought to be a mere 50 million years old,and the evolution of species is hotly debated.ORIGINS-Earth and Life ScienceToday:BR_warm_Journey-ORIGINSBefore ReadingGlobal ReadingDetailed ReadingAfter ReadingHomeThe plates(板 块)that make up the Earths crust(地 壳)move over time,causing earthquakes and volcanoes.The Earth is known to be 4,500 million years old.The genetic code of DNA,which drives evolution,is better understood every day.第7页BrainstormingBR_warm-Brainstorming-Brainstorm some1.Brainstorm some of the scientific and technological inventions.e-mailmobile

gland tissue(乳腺组织)of a six-year-old ewe(母羊),the first time scientists have been able to clone an adult mammal(哺乳动物).Before ReadingGlobal ReadingDetailed ReadingAfter ReadingHome第11页BR_warm_Clone-new-2 Dolly,the first-ever mammal to be successfully cloned from an adult cell,with her first lamb,named Bonnie,is seen at the Roslin Institute in Edinburgh,Scotland in this image on April 23,1998.Dolly,who was naturally mated at the end of last year with a Welsh Mountain ram（公羊）,gave birth to Bonnie on April 13,proving that despite her unusual origins,she is able to breed normally and produce healthy offspring.Before ReadingGlobal ReadingDetailed ReadingAfter ReadingHome第12页BR_warm_Clone-new-3 Dolly,the sheep,the first mammal to be successfully cloned from an adult cell,has been put down after she was found to have a lung disease,the Roslin Institute in Scotlands capital Edinburgh s a i d o n F e b 1 7,.“She was suffering from an incurable disease,”said Dr Harry Griffin,after Roslin released a

ethical and practical arguments both for and against cloning：For:Close1.Animals from endangered species could be 2.cloned to prevent extinction.2.Cloning would be a good source for organ and bone marrow(骨髓)transplants.3.Sterile（不育）couples will be able to have offspring who will have either the mothers or fathers genetic pattern.1.Technology is not well developed.It has a low fertility rate（出生率）.In cloning Dolly,277 eggs were used,30 started to divide,nine induced pregnancy,and only one survived to term(临产).2.Clones may be treated as second-class citizens and the unknown psychosocial harm with impacts on the family and society.3.Loss of genetic variation.CloseAgainst:Before ReadingGlobal ReadingDetailed ReadingAfter ReadingHome第14页BR_warm_Clone-Ads-11.Use

born in Ulm,Germany in 1879.As you may know,1905 was a big year for me.Thats when I turned the world upside down,at least for scientists,with several new ideas.I proposed that space and time had to be looked at in a whole new way-that Newtons view of space and time was inaccurate.These ideas became known as the special theory of relativity and introduced the equation E=mc2.Ten years later I presented the general theory of relativity.The general theory showed that gravity is not a force,as Newton had thought.It is instead a curvature（曲率）of the space-time continuum.MonologueBefore
