12.Dinosaurs ruled the planet for millions of years,and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us.Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.
The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.
According to Mark Norell,the director of the exhibit and an expert at the museum,it is based on new scientific evidence collected over the last two decades."I think this is really going to shake up the way people think of dinosaurs"Norell told reporters."One could argue that we still live in the age of dinosaurs."
The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds.It examines several properties that are shared between the two species,including feathers,complex brains,the shapes.And sizes of eggs,and the ability to fly.Birds today make nests,lay eggs and tend to babies.Fossil research shows that some dinosaurs also made nests and laid eggs.Also,birds have hollow(中空的)bones,which don't weigh much and allow birds to take more air into their lungs.These adaptations help with flight.Some dinosaurs had these properties as well.In addition,the exhibit shows that there are many similarities between the legs,claws; and feet of dinosaurs and birds.
Norell noted that the research behind this exhibit is the result of advanced scientific,techniques; and new technologies.For example researchers used a scanning (扫描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs.It combines with many X-rays to produce a 3D image."Modern technology tells us more than we thought we could ever know about the connections between dinosaurs and birds,"Norell said.

分析 科学家们一直在探索鸟类和恐龙之间的相似之处,新的研究表明恐龙和鸟类之间存在着很多的相似之处.

解答 32.D 主旨大意题.根据第一段最后一句Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.科学家们一直在探索鸟类和恐龙之间的相似之处;而新的研究表明,这两种动物是直接联系在一起的.可知本文主要讲恐龙与鸟类之间的联系,所以答案选D.
33.B 猜测词义题.根据后边的定语从句对这个词的解释that are shared between the two species,including feathers,complex brains,the shapes这两个物种共有的,包括羽毛,复杂的大脑,形状.这些都是动物的一些特征,character是名词"特征",所以答案选B.
34.B 细节理解题.根据These adaptations help with flight.Some dinosaurs had these properties as well.In addition,the exhibit shows that there are many similarities between the legs,claws; and feet of dinosaurs and birds.可见恐龙与鸟类不仅在腿、爪子和脚之间有许多相似之处,恐龙也有飞行的特征.birds have hollow(中空的)bones,鸟类的骨头是中空的,恐龙的骨头也有这种特征.所以答案选B.
35.C 细节理解题.根据前一句Norell noted that the research behind this exhibit is the result of advanced scientific,techniques; and new technologies诺雷尔指出,这背后表现出的研究是先进的科学、技术和新技术的结果;所以后文提到CT只是为了证明这项研究运用了先进的科技,所以答案选C.

3.What does it mean to say that we live in a world of persuasion?It means that we live among competing interests.Your roommate's need to study for an exam may take priority(优先)over pizza.Your instructor may have good reasons not to change your grade.And the object of your romantic interest may have other choices.
  In such a world,persuasion is the art of getting others to give fair and favorable consideration to our point of view.When we persuade,we want to influence how others believe and behave.We may not always prevail-other points of view may be more persuasive,depending on the listener,the situation,and the merits of the case.But when we practice the art of persuasion,we try to ensure that our position receives the attention it deserves.
  Some people,however,object to the very idea of persuasion.They may regard it as an unwelcome interruption into their lives.Just the opposite,we believe that persuasion is unavoidable-to live is to persuade.Persuasion may be ethical(合乎道义的) or unethical,selfless or selfish,inspiring or degrading.Persuaders may enlighten our minds or catch our vulnerability(弱点).Ethical persuasion,however,calls on sound reasoning and is sensitive to the feelings and needs of listeners.Such persuasion can help us apply the wisdom of the past to the decisions we now must make.Therefore,the most basic part of education is learning to resist the one kind of persuasion and to encourage and practice the other.
  Beyond its personal importance to us,persuasion is necessary to society.The right to persuade and be persuaded is the bedrock of the American political system,guaranteed by the First Amendment to the Constitution(美国宪法).
32.According to the passage,persuasion meansC.
A.changing others'point of view
B.exercising power over other people
C.getting other people to consider your point of view
D.getting people to agree with you and do what you want
33.The underlined word in the second paragraph"prevail"means"A".
A.win     
B.fail     
C.speak     
D.listen
34.The passage states that some people object to persuasion because they think it isC.
A.a danger to society      
B.difficult to do well
C.unwelcome behavior      
D.never successful
35.The passage mainly discussesD.
A.people's different opinions towards persuasion
B.the reasons why people persuade
C.that persuasion is both good and bad
D.that persuasion is important and it is all around us.

4.There is an old English saying:"laughter is the best medicine."Until recently,few people took the saying seriously.Now,however,doctors have begun to look into laughter and the effects it has on the human body.They have found that laughter really can improve people's health.
Tests were carried out to study the effects of laughter on the body.People watched funny films while doctors checked their heart,blood pressure,breathing and muscles.It was found that laughter has similar effects to physical exercise.It increases blood pressure,the heart beating and breathing; It also works several groups of muscles in the face,the stomach,and even the feet.If laughter exercises the body,it must be beneficial(有益的).
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body.In one experiment doctors produced pain in groups of students who listened to different radio programs.The group that tolerated(忍受) the pain for the longest time was the groups which listened to a funny program.The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which reduce both stress(压力) and pain.
As a result of these discoveries,some doctors in the United States now hold laughter clinics,in which they help to improve their patients'health by encouraging them to laugh.They have found that even if their patients do not really feel like laughing,making them smile is enough to produce beneficial effects similar to those caused by laughter.

28.Doctors have proved the following except thatA.
A.smiling does good to health     
B.laughter can be tolerated
C.there is a way to reduce pain    
D.laughter can work the muscles in the feet
29.The main idea of the passage isD.
A.laughter and physical exercise have similar effects on the human body
B.smile can produce the same effects as laughter
C.pain can be reduced by laughter    
D.laughter is the best medicine
30.The students whoD tolerated the pain for the longest time.
A.listened to different radio programs     
B.could produced a kind of chemical
C.don't have stress of pain              
D.listened to a funny program
31.Doctors hold laughter clinicsB.
A.to give better condition to their patients   
B.in order to improve patient's health
C.to make patients smile     
D.to prove smile and laughter have the same effect.

9.Many people know the names Alexander Graham Bell and Thomas Edison.However,most people don't know the name of the man who invented the television,Philo Farnsworth.

Later,Philo worked at many different jobs.He worked with trees.He worked on broken radios.He worked on trains.He also worked as a street cleaner.At last,two rich men heard about his idea for television,and they gave him the money to make it.On September 7th,1927,they watched Philo test the machine he built.When Philo turned on the machine,a small line could be seen on the glass.Philo said,"There you have it,electric television."
Later,a big company,RCA,said they had made the first television.Philo had to spend a lot of money on lawyers to fight them.Finally,he won.Then,World War Two started in 1939.During the war,Philo spent a lot of money helping the US army instead ofbuilding up   his television company.After the war,other bigger,richer companies started making televisions.In the end,Philo had to sell his company.
