When you go to work in the morning and find that traffic lights don't work, the traffic jam will certainly happen. A patient needs to be operated on at once. What will happen if the operation cannot be made because of the electricity. Without electricity, we can neither watch TV, listen to the tape, nor chat on line. Electricity is closely related to our daily life. How terrible it would be if there were no electricity!

当你早上去上班，发现红绿灯不亮，那么肯定会堵车。病人需要立刻进行手术。如果由于电的原因手术不能进行，那么会发生什么。如果没有电，我们既不能看电视，听磁带，也不在上网聊天。电力与我们的日常生活密切相关。如果没有电，这将多么可怕!
