3．"Today，technical innovations dominate our everyday life in many areas．New technologies，however，always are associated with risks--and these are also seen by laymen，"says Christoph B?hmert，first author of the recently published study and researcher of the Science Communication Group of KIT's Institute for German Studies．"It is crucial to enable adequate communication between science and society，which does not only consider scientific findings，but also concerns of the population．"The study clearly showed that communication of risks may be complicated sometimes．Information on efficient precautions was found to lead to an increased risk perception by the recipients of the information．
In their study，the researchers analyzed communication about a technology that has become indispensable in our life--mobile communications and the electromagnetic fields （电磁场）on which it is based．All over the world，radiation protection authorities，such as the German Federal Office for Radiation Protection，communicate the current state of research into risks of electromagnetic fields as follows：Investigations made and all findings obtained so far do not allow any conclusions to be drawn with respect to mobile communications being a risk for human health．But，the experts continue，there still are knowledge gaps as regards long-term impacts．Then，measures are recommended to reduce exposure of the individual to electromagnetic fields．
It had been known from previous studies already that information on precautions may increase worries．It had been suspected that people conclude from the recommendation of precautions that there really is a risk．This effect was not confirmed by the recent study．The scientists rather attributed the increased worries to a lack of knowledge about the propagation（传播） of electromagnetic fields．
Within the framework of the study，the recommended precautions were submitted to 1717Australians，together with one of six information brochures providing scientific background information．When test persons were given not only the recommendations，but also explained why observation of these tips strongly reduces their exposure to electromagnetic fields，worries increased．For example，scientists explained to the test persons that telephone conversations with a headset largely reduce exposure．When a mobile phone is located ten centimeters instead of just one centimeter away from the ear，the electric power absorbed by the ear is about one hundredth of the initial value．Hence，the own mobile phone usually causes an exposure that by far exceeds that of mobile communications stations that are generally referred to as"cellphone towers．"While the scientists wanted to explain the effectiveness of precautions，test persons mainly considered this information to be an indication of their mobile phone--not the transmission towers--being dangerous．As a result，they perceived increased risk potentials for telephone conversations with their mobile phones．
"The study reveals that messages on precautions and information are a double-edged sword in terms of subjective risk perception．Their use should be far better understood，"Boehmert says．

63．Which of the following statements is TRUE according to the passage？C
A．Adequate information on efficient precautions can relieve the concerns of the public
B．Mobile communications definitely do harm to people's health in the long run．
C．Information about technologies and their risks may have undesired side effects．
D．Observation of the precautions can help reduce the concerns of the public
66．According to the passage，we can conclude that the best way to relieve the inappriate worries is toA．
A．enable the users to know better of science and technology．
B．produce new electric products with a lower radiation value
C．provide the public with less information on effective precaution
D．inform the public about the potential risks with more patience
65．The word"precaution"（ first appears in paragraph 1）in bold letters has the closets meaning toB
A．introduction B．intention C．recommendation D．prevetion
66．Which of the following might be the best title of the passage？D
A．Science and Technology：A Double-edged Sword
B．Technical Innovation：Worries and Information
C．Science and Technology：Security Tips for Users
D．Technical Innovations：Effectiveness of Precautions．

7．Researchers in China and the United States have developed a new cataract（白内障）treatment with cells that has restored vision in babies in a trial and may eventually be used in adults．
The treatment-by doctors and staff members at the University of California，San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9edition of the scientific journal Nature．
A cataract is a clouding of the normally clear lens（晶体）of an eye．Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one．The new operation has been tested in animals and during a small，human trial．It resulted in fewer complications（并发症）than the current harmful operation，and in regrown lenses with superior visual function in all 12of the baby cataract patients who received the procedure．
A congenital cataract-lens clouding that occurs at birth or shortly after-is important cause of blindness in children．In the new research，Kand Zhang，head of ophthalmic genetics at US San Diego's Shiley Eye Institute，and his colleagues relied on the regrown potential of endogenous（同源的）stem cells．
According to Zhang，endogenous stem cells are different from other stem cells that are typically grown in a laboratory，transplanted into a patient，and can have risks of immune（免疫的）rejection，infection or cancers．Zhang told CBS News，"We invented a new operation to make a very small opening at the side of a cataractous lens bag，remove the cataract inside，allow the opening to heal，and promote potential lens stem cells to regrow an entirely new lens with vision．"
The human trial involved 12 babies under the age of 2 who were treated with the new method，while 25 babies received thee standard operation care..The latter group experienced a higher incidence of pos-operation danger，early-onset eye high blood pressure and increased lens clouding．The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure．

32．What is the text mainly about？B
A．The concept of the cataract
B．A new cataract treatment with stem cells
C．Bad effects of post-operation in the cataract
D．The reasons why the cataract comes into being
33．Which of the following best describe the new cataract treatment according to the passage？D
A．Convenient B．Comfortable C．Cheap D．Safe
34．What can we learn about the new cataract treatment？B
A．It has more risks
B．It may be used widely
C．It has been put into practice widely
D．It can only restore vision in babies
35．What does the underlined word"congenital"in the fourth paragraph mean？A
A．Born B．Strange C．Serious D．Dangerous．
