小学生10分钟应用题系列答案| 1 |  | A sign like this one means that there is a bike lane(车道). If there is such a sign，you are required to use the bike lane. If there is not such a sign, you should ride with traffic as far to the right side of the road as possible. |
| 2 |  | This signal means you can cross the street along with pedestrians(行人). It has a green picture of a oerson walking instead of using the word“walk”. |
| 3 |  | This signal is the “don’t walk”sign. It is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing. |
| 4 |  | Car drivers and bikers must come to a complete stop at“STOP” signs. |
| 5 |  | A“YIELD”sign means to slow down and be ready to stop. If there are pedestrians or vehicles in or near the crossroad, you must stop. If there is no traffic in or near the crossroad and it is safe, you may go through. |
| 6 |  | This signal means you are coming to a zebra crossing. Car drivers and bikers must stop to allow people in the zebra crossing to cross the street. |
| 7 |  | When people are working on the roads, parts of the road are often dug up or rough(不平整的). Be careful when yon are cycling. Rough roads could make you fall off your bike. If you must move into the road to go around a work area，you should stop and look carefully to be sure there is no traffic coming. |
| 8 |  | A detour is a way of getting around a roadway that is closed. Roads are usually closed because of road work or dangerous conditions. If you must take a detour, be careful about the roads you aren’t used to. |

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It’s always a good idea to put on your seat belt (安全带) when you’re in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won’t. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won’t go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn’t enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.
