新语篇 操作指南 Changing a light bulb can be dangerous. With some lights you cannot be sure whether the power is on or off. Before changing a light bulb, follow these tips.
You will need:
· A replacement light bulb. Know beforehand if the fitting needs a screw-mount (螺口) or a bayonet-mount (插口) bulb.
· A ladder or strong object to stand on, such as a wooden box, if the bulb is in a high ceiling.
· An assistant, if the light bulb has to be removed from a high-ceiling fitting.
Note: Change the bulb during daylight so that you can clearly see what you are doing.
Step 1 Make sure to turn off the light or lamp at the wall. You then know that the light will not be turned on—it can be surprising and dangerous if the light comes on in your hands as you plug (插入) the new bulb in!
Step 2 If you are replacing a working bulb with another type of bulb, allow a hot bulb to cool before touching it.
Step 3 If you have to use a ladder for an overhead light, have an assistant hold the ladder steady. The assistant can take the removed bulb and pass up the replacement bulb, which saves unnecessary messing around while you are on the ladder.
Step 4 For bayonet-fitting bulbs: Using your hand, put a little upward pressure on the glass bulb, and turn it anticlockwise (逆时针旋转) (as you look up at it). It will unlock the bulb shank from the metal frame. The bulb will come out downwards.
For screw-fitting bulbs: Grasp the bulb firmly and turn anticlockwise until it is freed from the socket.
Step 5 Insert a replacement bulb lightly and firmly into the socket, and turn it clockwise until it's snug. It is the opposite process to removing a bulb.
Step 6 Turn the light on to check that the bulb works and it has been correctly installed.
Step 7 Deal with the used bulb properly. Old bulbs are not recycled with other glass.

2. To change a light bulb in a high ceiling, a second person is required to ______.
A. make sure to turn off the power before starting
B. test the new bulb after the old bulb has been replaced
C. be sure the safety and effectiveness of the person on the ladder
