| A．The great impact and progress in genetic engineering B．Worries about privacy protection C．Worries about medical use of genetic engineering D．Genetic knowledge helps to predict diseases E．Genetic knowledge may not be properly used AB．The application of genetic engineering in the medical fields |
【小题1】__________
Current research into the human gene system is helping us understand why people have predispositions（易患某病倾向）to certain diseases．Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer．Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be．Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings．
【小题2】__________
The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases．Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes （中风）. But with the research that is now being conducted, we may find cures to many more diseases．In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.
【小题3】__________
Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against．Another problem is that many people do not want to discover their weakness．What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?
【小题4】__________
Many people believe that history has not always shown human decision-making to be bright when it comes to ethical（道德的）choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society．
【小题5】．__________
One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious． 查看习题详情和答案>>
Why do parents have such a difficult time to communicate openly and honestly with their teens? For this, there are many reasons but most of them stem from not being able to properly understand their teens. It is a dangerous gap because parents will have to communicate with their teens about a wide variety of issues during the most important years of their lives. Thus, parents must know how to communicate openly and honestly with their teens.
Here are a few tips to make communication easier between parents and teenagers.
1. Try not to talk down to your teens. Make them feel as if their views really matter, which not only helps your discussions with your teen but bring you closer to him.
2. Imagine what it would be like to be a teen. Try to remember some of the negative feelings you experienced as a teenager and apply it to your teen's situation.
3. Never make negative remarks to your teen about what she has said or done.
4. Remember how much courage it would have taken for your teen to come and talk to you about his personal issues. So listen respectfully.
5. Don't ignore your teen's feelings because it is usually a cry for help. For instance, if your teen is unusually angry, it may be time to spend a bit of quality time with your teen to determine what is wrong and where he is coming from.
It is, therefore, necessary for parents to strive to keep lines of communication open at all times with their teens. Try to remember what it was like to be a teenager and how vulnerable（脆弱的）you felt. Then you will be well on your way to help your teen communicate more openly and honestly.
1.Why don't teens want to talk about their personal issues with their parents?

In the near future，we may be using our eyes to operate our smart-phones and tablets，even when it comes to playing popular games like Fruit Ninja．
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years．But those devices have been firstly designed to help those with disabilities，and are very expensive．
“After a while，we figured out that probably the best way is to go for a mass-market way，” says Gaze’s Sune Alstrup Johansen．“where everybody would have this available．"
Johansen and some of his colleagues have formed a new company，the Eye Tribe，which is hoping to develop the technology on a mass commercial level．
The technology works with the help of the computing device toward the user’s face． After making sure of the user’s eye movements，the technology is then able to easily find where a person’s eyes are moving，and then allow the eyes to control a cursor（光标）．
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at，“reads an explanation on the Eye Tribe site．
There has been a gradual change toward hands-free technology in recent years， particularly in the gaming world．Recently Xbox released the Kinect device，which lets users control their Xbox and play certain games using only their hands，legs and voices． But still，most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device．Johansen said a replaceable filter（滤光器）would be a cheap，convenient way for most consumers．
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

New crime prediction software should reduce not only the murder rate, but the rate of other crimes. Developed by Richard Berk, a professor at the University of Pennsylvania, the software has already used in Baltimore and Philadelphia to predict which individuals on probation(缓刑) or parole(假释) are most likely to murder and to be murdered.
????? “When a person goes on probation or parole he is supervised(监督) by an officer. The question is ‘what level of supervision is appropriate?’” said Berk. It used to be that parole officers used the person’s criminal record, and their judgment to make decisions.
??? “This research replaces those seat-of-the –pants calculations,” he said.
??? Technology helps determine level of supervision. On average there is one murder for every 100,000 people. Even among high-risk groups the murder rate is one in 100. Predicting such a rare event is very difficult, but advances in computer technology works.
?? Years ago, the researchers made a dataset of more than 60,000 various crimes. Using the software they developed, they found some much more likely to commit murder when paroled or probated. They could identify eight future murderers out of 100.
??? Berk’s software examines roughly two dozen variables(可变因素), from criminal record to geographic location. The type of crimes, and more importantly, the age at which that crime was committed, were two of the most predictive variables.
???? “People assume that if someone murdered then they will murder in the future,” said Berk. “ What really matters is what that person did as a young individual. Predicting future crimes sounds well. But we aren’t anywhere near being able to do that.”
???? “Berk’s scientific answer leaves policymakers with difficult questions. By labeling one group of people as high risk, and supervise them closely, there should be fewer murders, which the potential victims should be happy about. It also means that those high-risk individuals will be supervised more aggressively. For human rights advocates, that means punishing people who, most likely, will not commit a crime in the future,” said Bushway. “It comes down to a question of whether you would rather make these errors or those errors.”
1.The underlined words(in Para.3) probably mean___.?
A. calculations based on subjective opinions?????
B. calculations based on widespread voting
C. calculations made by advanced technology????
D. calculations based on serious considering
2.For 650 people with crime records, how many potential murderers would the software find?
A. 6.5.?????? ????????????? ????????????? ????????????? B. 13.??????? ????????????? ????????????? C. 52.??? ????????????? ????????????? ????????????? D. 65.
3.From Para 7, we can infer that______.
A. the technology developed by Richard Berk will soon be widely used in the US
B. the technology would not be widely accepted in the short term
C. whether a person murders or not largely decided by his upbringing while young
D. if a person murdered when he was fifty, he is sure to murder again while on probation
4.Bushway’s attitude to the technology put forward by Richard Berk is ____.
A. positive???? ????????????? ????????????? B. negative?? ????????????? ????????????? C. objective??? ????????????? ????????????? D. indifferent
5.Which would be the best title for the passage?
A. Closely Supervise Potential Murders?????????
B. Measures Taken to Prevent Criminal Behavior
C. Technology Revolutionizes Judges’ Way of Working????
D. Software is Developed to Predict Criminal Behavior
