愉快的寒假南京出版社系列答案【题目】 You can’t play, run, skate or ride a bike on the railroad ( 铁 路 ). There are many places where the railroad tracks ( 轨道) cross the roads or streets. Many of these railroad crossings are marked with the signs in the table below.
| This sign means you are coming to a railroad crossing. Always look both sides and listen carefully to be sure a train is not coming from either direction before you go across the tracks. |
| Many railroad crossings have a gate with flashing lights. The gate will close whena train is coming ● NEVER play around a closed railroad gate. ● NEVER try to get across the tracks before the train gets there. |
| Some railroad crossings which don’t have gates may have this sign. When the lights are flashing, a train is coming. You should wait until the train passes instead of trying to cross the tracks. |
Be careful when crossing road tracks:
* Railroad tracks are uneven (凹凸不平的). You should not bicycle, skate or run when crossing the tracks.
* Trains are very large and heavy, so they need take a long time to stop.
* Sometimes when a train has just passed from one direction, another train may come from the opposite direction. You may not notice the second train because of the noise of the first train.
