6.You Are What You Eat
Genetic(基因的)engineering is the scientific change of the genetic material in a living organism. It allows scientists to identify specific genes,to remove them from an organism's chromosomes (染色体),improve them,analyze them,and possibly clone them,and to then reinsert the changed gene into the original organism,or a completely different organism.Unlike traditional breeding (繁殖),where a desired quality would be bred within the same species,genetic engineering can insert desired ones into organisms of different species.Wow…Did you catch that?
Genetic engineering creates many positive contributions to agriculture. For example,by genetically engineered(GE) foods,anti-cancer agents,minerals and vitamins can be increased.Improved taste,shelf life,and better transport are all possible.Also,GE plants can increase pest and bacterial resistance,therefore,making the food safe for consumers.
But some argue that the possible negative effects outweigh the positives,and critics are starting to voice their concerns.  Unlike Europe,in the United States labeling is not required on genetically engineered foods or on foods that contain genetically engineered products. Most Americans do not realize that they are,in fact,eating GE foods.
The public is also concerned about the unknown health risks.With limited understanding of genes,scientists cannot predict possible effects.Because most genes introduced into GE plants come from sources not introduced into the human body,it is impossible to know if they will cause reactions. Moreover,due to the lack of labeling if allergies develop,it will be extremely difficult to find the origin of them.
There is also a major moral question in many minds.For many,the conflict is not if it is safe or not,but it disturbs them because it is unnatural and unnecessary.We are currently producing one and a half times the amount of food needed to feed the world,yet one in seven people are starving.GE food is unnecessary,and fails to address the root of hunger. Many believe that the only people who will benefit are the corporations that produce it.
Scientists cannot foresee t.he possible effects of GE foods,yet we eat them every day without even knowing it.We already have enough food,so why create more that could be potentially harmful to us,to the Earth and to all wildlife?I think that the benefits are amazing,but until we know for sure how these foods will affect us,they are not worth the risk.

67.According to the passage,traditional breeding is different from genetic engineering in thatC.
A.traditional breeding changes the genes in the same species
B.traditional breeding changes the genes in different species
C.traditional breeding takes place within the same species
D.traditional breeding is more scientific
68."The lack of labeling"in Paragraph 4indicatesA.
A.information concerning gene sources is unavailable to customers
B.it is currently possible to find the origins of some allergies
C.scientists try to hide potential dangers from customers
D.the US government is responsible for GE food
69.According to Paragraph 5,GE food is unnecessary becauseA.
A.it won't help solve the problem of hunger in the world
B.there are potential dangers in producing GE food
C.we're now producing more food than before
D.customers will benefit from GE food
70.What is the author's attitude towards genetic engineering?B
A.Welcoming.  B.Disapproving.   C.Unconcerned.   D.Optimistic.

分析 本文主要介绍了基因工程技术.基因工程可以将所需的生物转化为不同物种的生物,它为农业做出了巨大的贡献.而转基因食品是不必要的,因为它不会帮助解决世界上的饥饿问题,并且还可能存在一些隐患.

解答 67.C推理判断题.根据第一段Unlike traditional breeding (繁殖),where a desired quality would be bred within the same species,genetic engineering can insert desired ones into organisms of different species.可知传统育种不同于基因育种,传统育种发生在同一物种之间.故选C.
68.A细节推理题.根据第四段due to the lack of labeling if allergies develop,it will be extremely difficult to find the origin of them.可知由于缺乏信息的记录,如果过敏原发展,将很难找到他们的起源.由此推知,"The lack of labeling"暗示了关于基因的来源对于客户来说是不可获取的.故选A.
69.A细节理解题.根据第五段GE food is unnecessary,and fails to address the root of hunger.可知转基因食品是不必要的,因为它不会帮助解决世界上的饥饿问题.故选A.

6.It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken.In Apple's case,developers can also obtain the location information for each photo.
Senator(参议员) Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday.
"We asked them if they could find a way on their own to prevent Apple from having access to private info,"Mr.Schumer said."They were friendly and open to the idea that this ought to be changed."
On Sunday,Mr.Schumer said that he planned to send a letter to the Federal Trade Commission(联邦贸易委员会) asking the agency to investigate Apple and Google after the privacy concerns came to light.Claudia Bourne Farrell,an F.T.C.spokeswoman,said the agency had received the letter but she could not comment further.
"It sends shivers up the spine to think that one's personal photos,address book,and who knows what else can be obtained and even posted online without consent,"Mr.Schumer wrote in his letter to the F.T.C."If the technology exists to open the door to this kind of privacy invasion,then surely technology exists to close it,and that's exactly what must happen."
Mr.Schumer said if Apple and Google could not come to an agreement to fix the problem,then he would be forced to take the issue further.
He said other companies had been willing to work with his office to fix issues."I'm optimistic that we can get this changed without any regulation,"he said."If it's not changed,then we'll look the F.T.C.,and if that doesn't work then we'll look at legislative approach."
The F.T.C.has warned companies to try to be more vigilant(警醒的) in their efforts to protect consumers when it comes to privacy.

37.Which of the following statements is true?D
A.Privacy invasion from Apple has existed for a long time.
B.Privacy invasion from Google has existed for a long time.
C.Apple and Google have decided to make a change.
D.Mr.Schumer takes the privacy concerns caused by Apple and Google seriously.
38.Mr.Schumer's letter to the F.T.C.mainly shows that the technology to open the door to privacy invasionA
A.causes people to worry about the safety of their personal information.
B.can be used if permitted.

15.The story began on a downtown Brooklyn street corner.An elderly man had collapsed while crossing the street,and an ambulance rushed him to Kings County Hospital.There,when he came to now and again,the man repeatedly called for his son.
From a worn letter located in his pocket,an emergency room nurse learned that his son was a marine stationed in North Carolina.Apparently there were no other relatives.
Someone at the hospital called the Red Cross office in Brooklyn,and a request for the boy to rush to Brooklyn was sent to the Red Cross director of the North Carolina Marine Corps camp.Because time was short---the patient was dying---the Red Cross man and an officer set out in an army vehicle.They found the young man walking through some marshes (沼泽) in a military exercise.He was rushed to the airport in time to catch the only plane that might enable him to reach his dying father.
It was dusk when the young marine walked into the entrance lobby of Kings County Hospital.A nurse took the tired,anxious serviceman to the bedside.
"Your son is here,"she said to the old man.She had to repeat the words several times before the patient's eyes opened.The medicine he had been given for the pain from his heart attack made his eyes weak and he could only see the shadow of the young man in Marine Corps uniform standing outside the oxygen tent.He reached out his hand.The marine wrapped his strong fingers around the old man's weak ones,squeezing a message of love and encouragement.The nurse brought a chair,so the marine could sit by the bed.
Nights are long in hospitals,but all through the night the young marine sat there in the dimly lit ward (病房),holding the old man's hand and offering words of hope and strength.Occasionally,the nurse urged the marine to rest for a while.He refused.
Whenever the nurse came into the ward,the marine was there,but he paid no attention to her and the night noises of the hospital---the banging of an oxygen tank,the laughter of the night staff exchanging greetings,the cries and breathing of other patients.Now and then she heard him say a few gentle words.The dying man said nothing,only held tightly to his son through most of the night.
It was nearly dawn when the patient died.The marine placed the lifeless hand he had been holding on the bed,and went to inform the nurse.While she did what she had to do,he smoked a cigarette,his first since he got to the hospital.
Finally,she returned to the nurse's station,where he was waiting.She started to offer words of sympathy,but the marine interrupted her."Who was that man?"he asked.
"He was your father,"she answered,shocked.
"No,he wasn't,"the marine replied."I never saw him before in my life."
"Why didn't you say something when I took you to him?"the nurse asked.
"I knew immediately there'd been a mistake,but I also knew he needed his son,and his son just wasn't here.When I realized he was too sick to tell whether or not I was his son,I guessed he really needed me.So I stayed."
With that,the marine turned and left the hospital.Two days later a message came in from the North Carolina Marine Corps base informing the Brooklyn Red Cross that the real son was on his way to Brooklyn for his father's funeral.It turned out there had been two marines with the same name and similar numbers in the camp.Someone in the personnel office had pulled out the wrong record.
But the wrong marine had become the right son at the right time.And he proved,in a very human way,that there are people who care what happens to their fellow men.
 
50.An emergency room nurse found out that the old man's son was a marineC.

  B.the marine did not tell the truth at the hospital until some time later
  C.the marine told the real story about him and the old man
  D.the marine made the right decision about what he should do.
