9．What should you do if you want to cross the road in Singapore
10．Are strict rules good for a country Why
Wherever we go, no matter how old we are, we must follow safety rules. Though many people might not see the purpose of stopping at a stop sign or driving at the speed limit, rules keep us safe.
People start to learn about the importance of rules when they are children. There are many rules that teach children how to keep themselves and their friends safe. For example, children learn safety rules when they walk in the hallway at school. They are told not to run because they may hurt themselves or run into another student. In the lunch room, children are taught to sit nicely while they are eating to avoid being choked (噎住). In the playground, they are told to use the equipment (设备) properly. For example, they should not go down the slide backward or climb up the slide when someone is going down because there can be an accident.
High school students will also be given safety rules but at a different level than younger children. High school students may be taught, for example, safety rules in the science lab. Lab safety is very important because if one thing is done wrong, it can result in a fire or a bad accident.
11．Why must we follow the safety rules

6．有A、B两根长度相同、材料相同、粗细不同的导体，按甲、乙、丙、丁四种方式将其连入电路。则连入电路的电阻大小的顺序排列应是（ ）
A． B．
C． D．
【答案】B
【详解】甲乙两图中，AB长度和材料相同，B的横截面积小，B的电阻较大，即
R乙>R甲
丙图中AB并联，丁图中AB串联，由串并联电路电阻的规律可知丙图中总电阻最小，丁图中总电阻最大，所以甲、乙、丙、丁四种方式连入电路的电阻大小的顺序排列是
