问题 The United States calls for some countries to research the bionics since 1960. [br] Transducers are instruments like a microphone, TV camera, radio or phonograph, which convert one form of energy into another.

选项 A、Y
B、N
C、NG

答案 A

解析 第九段中间一句话指出"…transducers—instruments like a microphone,TV camera,or phonograph pickup arm—which convert one form of energy into another".像麦克风、电视摄像头、留声机等传感器可以把一种形式的能量转换为另一种形式,与题干表达的意思正好相符,因此答案正确。
