【填空题】Lesson 15 Listening Comprehension-1 Fill in the Blanks with what you have heard On TCAS As the direct result of accidents in 1980s leads to the wide-spread introduction to an (1) clever piece of new technology. It is called TCAS—traffic collision avoidance system. TCAS relies on a clever piece of technology called transponder--a device both (2) to radio signal. When 2 aircraft approach each other their transponders lock on and start to talk to each other. Terry is to train the pilots to use TCAS. The transponders of the aircraft (3) each other many times a second, In doing so it creates a (4) radio bubbles around each aircraft. if any time it senses those 2 bubbles might come too close for comfort, TCAS will (5) to pilots must react. And the approaching plane show up as a (6) , you can see we have got traffic below . it is climbing indicated by the arrow. It is now 600 feet below. Radio bubble is too close for comfort, the white diamond will change into an (7) . TCAS flashes up warning “ traffic, traffic” that is now (8) , 500feet below and still climbing. If the situation gets serious, the orange circle becomes (9) . TCAS orders the plane to (10) “ clime , climb” Now it is (11) . So i need to (12) the aircraft to avoid the traffic. In the simulation, TCAS orders one plane to climb and the other to descend. TCAS steers the aircraft away from each other. “ clear of traffic” and re-engaging the autopilot, and two bubbles in which the aircraft is sitting moves to safe distance apart. Technology seems to finally (13) that pilots are not able to see each other. As a direct result of LA collision, TCAS is now (14) on all commercial aircraft flying to most destinations. But TCAS system designed to (15) would one day play a part in one of the worst collisions of modern times.

【填空题】Most systems are constructed around a （1）, a metal （2） containing a series of slots linked through a （3）, to a 16- or 32-bit processor. Memory is added by plugging a （4） board into one of the open slots. Without input and （5）, the computer is useless, so a display （6） is plugged into another （7）, and a display unit connected to it. A （8） is plugged into a special slot on motherboard. A printer can be attached through a （9） interface. And if a diskette interface is plugged into an open slot, a diskette drive can be added. At this point, you have got a complete （10） system.
