            • 1． A new camera made by a company named Netatmo has facial recognition software （识别系统） that can tell parents at work that their children have returned from school，or that a package has been taken to their home．It can also tell them if a stranger has entered their home．
              Janina Mattausch is a product marketing manager for Netatmo．
              "The common security （安全） cameras at present are not that smart．So，they can tell you if something is moving but they don't necessarily know if it's a human being or，ah，if it's your kids--they don't know the difference，so they will warn you all the time．"
              When family members enter a home，the new camera"recognizes"（识别 ）  them and sends information to the owner's smartphone．The owner can choose to see the video then or later．But if an unknown person enters a home，the camera will send the owner a warning that will cause an alarm to sound on the owner's smartphone．
              That is what happened recently to a smart home camera owner named Darrmen．He lives in Paris．
              "On a Friday I was at work，atending a big monthly meeting when my phone warned．At first I told myself'Oh，it must be a mistake，maybe I have to set the system again．'-but the notice on my phone was telling me that there was a movement in my flat and also a face that the software did not recognize．"
              He watched the video and was very surprised by what he saw．
              "I saw a person I did not know with his shoes on．I was watching it live on video．So I felt totaly unbelievable，frozen．I asked a workmate to take me back home as fast as possible and I called the police on the way．"
              With the help of the video，the police found the intruder （闯入者） later that day．

              38．The new camera made by Netatmo can    ．
              A．warn the strangers                        
              B．recognize the comers
              C．stop the visitors                          
              D．welcome the children
              39．The fourth paragraph mainly tells us    ．
              A．where the new camera is placed           
              B．what the new camera looks like
              C．when the new camera is used             
              D．how the new camera works
              40．We can learn from the passage that Damien    ．
              A．found the warning was a mistake

              D．caught the intruder by himself that day

            • 2． （2014•泉州）    If your pen broke at school today，what would you do？You would go to a shop and buy a new one．What if you could simply print out a real，working pen with your 3-D printer without leaving your room？
                Ten years ago people could only see 3-D printing in science fiction movies．But now 3-D printing is here and it’s bringing big changes．
                Unlike normal printing that can only copy a 2-D picture with ink.3-Dprinting can build almost anything made from material．The printer layers（分层） the material in different shapes to create the object you want to be copied．
                The 3-D printer has been used to make many different things．People have made cups cars and even an airplane with it．
                Doctors have been using 3-D printers for several years．People’s nervous systems have been printed out in 3-D form medical research．Some body parts have been printed and used in hospital．Several months ago，doctors used a 3-D printer to rebuild the face of a person who had a bad accident．In the future，it is expected that the printer will make human organs to save more lives．
                However there are drawbacks to the printer．At the moment，printing can be quite slow and it’s still rather expensive．The average（平均的） price of a household printer is around $1，700，not including the cost of the materials．
                 But as the technology develops，it shouldn’t be long before disadvantages are improved．Only time will tell where this new technology will take us．

              61．People could see 3-D printingin     ten years ago．
              A．large high school

              A．The normal printer can build 3-D objects y ou mant．
              B．No nervous systems are printed out in 3-D form．
              C．The 3-D printing can be cheaper and faster in the future
              65．What’s the best title of the passage？    
              A．The disadvantages of 3-D printing      
              B．the changes brought by 3-D printing
              C．The rapid development of science．
