3．London has become a cycle-friendly zone after the launch of a new bike hire scheme．It has been designed to encourage more people to cycle in and around central London．
So how does it work？First you have to sign up for the scheme to be sent a key．The key will unlock one of the bikes，which are kept at docking stations in and around central London．You have to pay an access fee for the key and then you pay as go for the length of time you use the bike．
Transport for London，which runs the scheme，is hoping to have 6，000bikes and 400docking station in place by the end of the year．The new hire system is hoping to ease congestion（拥挤）in London and is expected to create up to 40，000extra cycle trips a day into the city centre．London Mayor Boris Johnston launched the scheme and said London had been"filled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses"．
However，there have been a few problems since the scheme was launched last Friday．On the first day some people found they couldn't dock their bikes properly and that their usage of the bikes had not been registered．Transport for London did admit they had been expecting a few"teething problems"and said they wouldn't charge for the first day as a"gesture of goodwill"．Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles．
Despite the comments，the green-thinking London Mayor still seems very positive about things，saying，"My campaign for the capital to become the greatest big cycling city in the world has taken a big pedal-powered push forwards．"
28．London Mayor Boris Johnston launched the new bike hire scheme in order toB．

20．Robot Surgeon（外科医生） Succeeds without Help from Human Doctors
Humans make mistakes．Even surgeons with years of experience are not infallible．But what if these doctors could pool their knowledge and experience together and create a surgical standard of care，to be carried out by machines？
That's the idea behind surgical robots，which may soon perform most surgeries，from sewing up tiny wounds to performing heart procedures．Many of these operations are，in fact，already completed with the assistance of robots．But a recent test suggests that robots in the operating room may soon go a step further，performing on soft tissue completely on their own，from start to finish．
The Smart Tissue Autonomous Robot（STAR），successfully completed surgeries on pigs．"We're the first group to develop autonomous robotic surgery with soft-tissue surgery，and when compared to standard operation，it's better，"says Peter Kim，professor of surgery．"The idea is not to replace surgeons； it will make the surgeons better and make the procedures safer．"
A recent Mayo Clinic study found that major surgical errors-including operating on the wrong site or side of the body，or even leaving tools or objects inside the patient-occur every one out of 22，000procedures．That's rare，but robots like STAR would aim to lower the number even further．
In the da Vinci surgical system，surgeons place their arms inside instruments and use their hands to control the movement of robotic tools on the operating table from afar．The robot's every major move is controlled by surgeons，and thus its results may vary based on the surgeon's training or experience．
STAR，on the other hand，is entirely autonomous．It's not only able to work on its own and perform surgeries with a more flexible"hand"，but it's able to react to the unexpected incidents．Cutting into hard tissue like bones is one thing，but operating on moving soft tissue is far more complex．STAR reacts to a changing environment，similar to how self-driving cars are programmed to not only drive on the highway，but also react to another driver making a mistake and getting in your way．

63．The underlined word"infallible"in Paragraph 1probably meansA．
A．always right
B．really creative
C．rather responsible
D．quite smart
64．We can learn from the passage that STARB．
A．has been widely used in the operating room
B．can perform the operation on its own
C．can make surgeries much faster
D．will take the place of surgeons
65．In the da Vinci surgical system，B．
A．robots are trained from afar
B．surgery results depend on surgeons
C．robots always make mistakes
D．surgeons have trouble controlling robots
66．In the last paragraph，the author mentions self-driving cars in order to showC．
A．how bad getting in another driver's way might be
B．how difficult self-driving on the highway is
C．how smart an autonomous robot can be
D．how dangerous operating on people is．

1．A new commodity brings about a highly profitable，fast-growing industry，urging antitrust（反垄断）regulators to step in to check those who control its flow．A century ago，the resource in question was oil．Now similar concerns are being raised by the giants（巨头）that deal in data，the oil of the digital age．The most valuable firms are Googole，Amazon，Facebook and Microsoft．All look unstoppable．
      Such situations have led to calls for the tech giants to be broken up．But size alone is not a crime，The giants'success has benefited consumers．Few want to live without search engines or a quick delivery，Far from charging consumers high prices，many of these services are free （users pay，in effect，by handing over yet more data）．And the appearance of new-born giants suggests that newcomers can make waves，too．
      But there is cause for concern．The internet has made data abundant，all-present and far more valuable，changing the nature of data and competition．Google initially used the data collected from users to target advertising better．But recently it has discovered that data can be turned into new services：translation and visual recognition，to be sold to other companies．Internet companies'control of data gives them enormous power．So they have a"God's eye view"of activities in their own markets and beyond．
      This nature of data makes the antitrust measures of the past less useful．Breaking up firms like Google into five small ones would not stop remaking themselves：in time，one of them would become great again．A rethink is required-and as a new approach starts to become apparent，two ideas stand out．
      The first is that antitrust authorities need to move form the industrial age into the 21st century．When considering a merger（兼并），for example，they have traditionally used size to determine when to step in．They now need to take into account the extent of firms'data assets（资产） when assessing the impact of deals．The purchase price could also be a signal that an established company is buying a new-borm threat．When this takes place，especially when a new-born company has no revenue to speak of，the regulators should raise red flags．
      The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them．Companies could be forced to consumers what information they hold and how much money they make from it．Governments could order the sharing of certain kinds of data，with users'consent．
      Restarting antitrust for the information age will not be easy．But if governments don't wants a data oconomy by a few giants，they must act soon．

61．Why is there a call to break up giants？A
A．They have controlled the data market．
B．They collect enormous private data．
C．They no longer provide free services．
D．They dismissed some new-born giants．
62．What does the technological innovation in Paragraph 3 indicate？C
A．Data giants'technology is very expensive．
B．Google's idea is popular among data firms．
C．Data can strengthen giants'controlling position．
D．Data can be turned into new services or products．
63．By paying attention to firms'data assets，antitrust regulators couldB．
A．kill a new threat
B．avoid the size trap
C．favour bigger firms
D．charge higher prices
64．What is the purpose of loosening the giants'control of data？D
A．Big companies could relieve data security pressure．
B．Governments could relieve their financial pressure．
C．Consumers could better protect their privacy．
D．Small companies could get more opportunities．
