    houses, our cookers, our hot water systems. We can    11     the controls to the temperature we want. The
    robot does     12   . Its feedback usually come    13    thermostat (自动调温器).
         Our kind of thermostat is a strip of metal (金属条), which bends (弯曲) when it gets hot. At the right
    temperature, it bends just enough    14    a switch. This turns off the heat. As the air around it gets     15   ,
    the metal gets straight, and this turns the heat on again.
