Directions: In this section, you will hear a passage three times. When the passage is read for the first time, you should listen carefully for its general idea. When the passage is read for the second time, you are required to fill in the blanks numbered from 36 to 43 with the exact words you have just heard. For blanks numbered from 44 to 46 you are required to fill in the missing information.

In the past, one of the biggest disadvantages of machines has been their inability to work on a micro-scale. For example, doctors did not have devices allowing them to go inside the human body to (36) _____ health problems or to perform (37) _____ surgery. Repair crews did not have a way of (38) _____ broken pipes located deep within a high-rise (39) _____ building. However, that's about to change. Advances in computers and biophysics have started a microminiature (超微) (40) _____that allows scientists to envision – and in some cases actually build – microscopic machines. These devices promise to (41)_____ change the way we live and work.
Micromachines already are making an impact. At Case Western Reserve University in Cleveland,Ohio, research scientists have designed a 4-inch silicon chip that holds 700 tiny (42) _____motors. At Lucas NovaSensor in Fremont, California, scientists have perfected the world's first
microscopic blood-pressure sensor. Threaded through a person's blood (43) _____, the sensor can provide blood pressure readings at the valve of the heart itself.
(44) ______________________________________________________________________. Auto manufacturers, for example, are trying to use tiny devices_______________________________________________________
(45)___________________________________________________________________________. Some futurists envision nanotechnology (纳米技术) also being used to explore the deep sea in small submarines, or even to launch finger-sized rockets packed with microminiature instruments.
There is an explosion of new ideas and applications. So, (46) _____________________________
