2 . Remember solar roadways, where solar panels were embedded (嵌入) in roads? The idea of the solar roadway seems attractive because the solar resource is everywhere, and someday there will be a lot of electric cars that will need charging. But for me, the idea has little to recommend it. There is another kind of road — the railway — that might be a much better place for solar panels. And that’s what is happening in Germany, where the British company Bankset Energy is installing solar panels between the rails.
As estimated, 100 kilowatts of electricity can be generated per kilometer of railway line. Since the rail network in Germany is over 60,000 kilometers long, the power that can be generated is comparable to the output of five nuclear power plants in total.
But, why is putting solar panels is a railway better than a roadway? Trains generally stay on the rails, so there is no need to have solar panels designed to take any serious load. Although there is a serious amount of vibration, the panels wouldn’t shake apart. Railways usually own their rights of way and restrict access, so they have much better control. They also own the electrical infrastructure, which is right overhead and can directly use the electricity. German railways have been trying to justify hydrogen-powered trains because it was too expensive to electrify many of their lines. Turning their rail beds into power sources might change the economics.
On the other hand, rail rights of way are generally a lot wider than the tracks; it might make more sense to fix the panels next to the tracks, pointing in the right direction instead of lying flat. German Rail is already a huge consumer of solar power from more conventional installations.

5 . If you frequent any kind of public transportation, then you’re well aware of certain types of passengers and passenger habits that are annoying. But it’s not just other passengers that get angry, there are certain things that drive the train attendant crazy.
We’ve all been there in that moment when someone boards a train trying to take several huge items with them to wherever they’re trying to go. They wind up taking up way too much space and blocking seats.
For some reason, people have a bad habit of talking very loudly to one another to a point where you can hear them from opposite sides of the train cart (车厢). This goes for playing music as well. Some people like to play music through their phone. This really bothers fellow passengers on the train.
A.Being really loud |
B.Arguing with others |
C.Here are some of the most annoying things |
D.Then who would be in charge of playing music on the train |
E.It’s one thing if you’re having something small such as an apple |
F.This can make things uncomfortable for everyone else on the train |
G.Plus when other passengers complain, guess who has to take care of it |
A.By train. | B.By bus. | C.By car. |
7 . School Bus Safety in the United States
Each school day, millions of children ride school buses. Do you know that the school bus is one of the safest vehicles on the road? Less than 1% of all traffic deaths involve children on school transportation vehicles. However, children are more at risk when approaching or leaving a school bus. It’s important for you to understand school bus safety.
Stop for School Buses
When you see a school bus slowing down or stopping, it’s not just the bus that you need to have your eyes on — but the surrounding area, too. Children wait at least several feet away from a bus and often cross the street when they’re boarding or getting off the bus. This is why you must stop for school buses, and don’t attempt to pass.
Illegal School Bus Passing
Illegal school bus passing poses a significant threat to children and others on the road. In every state, it is illegal for you to pass a school bus while the stop-arm is extended and the red lights are flashing.
Understanding School Bus Lights
Learn the school bus laws in your state and always follow them, as well as the flashing lights that school bus drivers use to warn you.
Yellow flashing lights indicate the bus is preparing to stop to load or unload children. You should slow down and prepare to stop your vehicle.
Red flashing lights and extended stop-arms indicate the bus has stopped and children are getting on or off. You must stop your car and wait until the red lights stop flashing, the extended stop-arm is withdrawn, and the bus begins moving, before you can start driving again.
