笔试部分
六、
As we all know, electricity is important in our life, but sometimes it is also very dangerous. So when we use the electrical appliances, we must be careful with them. First, if our hands are wet, we mustn’t touch them. Second, the electrical appliances can’t work too long and we should make them stop to have a rest. Third, we mustn’t let children touch some of the electrical appliances. Last, when we clean or repair the electrical appliances, we must switch off the power supply.
