It was about eight o'clock in the morning. I was on my way to work in a subway.
Nobody had expected something unusual would happen later and everyone was doing their usual. Sitting next to me, a middle-aged gentleman with glasses enjoyed reading newspaper leisurely. On my right, a young woman with a suitcase and a baby took a scarf out of her suitcase and made her baby a nest, so that it could lie more comfortably. Shortly after the train set off, instead of speeding up, it started to slow down and then came to a stand-still.
Ten minutes passed, though it seemed like half a day. The train didn't move. Had the railway men forgotten all about our existence? Had there been a crash on the line in front? How serious was the breakdown? We had no means of knowing. However, to anxious people who were stuck there, I suppose it didn't really matter what it was that had broken down. What they cared about was when they could get out of the trouble.
Thirty minutes passed. All hope of getting to work on time had long since gone. Had the train really broken down? Several people thought so. A railway man at last came down the length of the train to tell us that the power supply had failed and that we were not to worry as they were working to put it right.
We could not leave the train, as it had stopped in the tunnel (隧道), not at a station. There was nothing else to do. The faint light of the emergency lamp blurred everything. The weak signal disabled cell-phones. Besides, the train was getting hot and stuffy (闷的). I even began to wonder if we were going to stay there for the rest of the day.

“Pedelec”, or pedal electric-assisted bikes like the one I rode, can end that worry. They look and act like traditional bicycles, but their motors make pedaling much easier when required. Sometimes called the most energy-efficient motorized mode of transportation ever built, they’re also incredibly green.

6 . Commuting to and from work can be a nightmare. Cars advance slowly in stop and go traffic, crawling from one traffic jam at stoplights to the next. At peak rush hour especially, there is no chance of sailing through a series of green lights. Now, thanks to artificial intelligence, German researchers have found a way to reduce time spent at the crossroads.
Called the KI4LSA project and funded by the Ministry of Transport and Digital Infrastructure, the innovation is being tested. Scientists first studied algorithms taken from a busy intersection to learn about traffic patterns and where improvements were most needed. Then, the technology, using high-resolution cameras and radar sensors, more precisely captured the actual traffic situation and detected the average speed of the cars and their waiting times. Finally, the AI uses deep enhanced learning algorithms to calculate the best switching behaviour for the traffic lights and determine the best phase sequence to shorten waiting times at the crossroads.
The results are encouraging when it is being tried out at a busy intersection in Lemgo, Germany. The intelligent lights are said to improve traffic flow by 10 to 15 percent, which results in money saved; the EU estimates that traffic jams create economic damage that adds up to 100 billion euros a year. Aside from reducing commuting time, these traffic lights will reduce noise and CO2 emissions from cars waiting at the crossroads.
Another exciting development in this research is the K14PED project, which studies pedestrians crossing the crossroads. Using AI as well as a 3D points cloud, researchers can identify how many people are waiting at a pedestrian crossing and whether some of the disabled or elder people will need extra time to cross the street. Such a needs-based system could reduce pedestrian waiting time by 30 percent, which could then decrease jaywalking (乱穿马路) by 25 percent.
Researchers are optimistic that it will be adopted by many countries after the tests in the German towns of Lemgo and Bielefeld. This technology is exciting news for pedestrians and drivers alike. It encourages safety, protects the environment, and may even give you more time to enjoy your morning coffee before heading off to work!

9 . Transport has a lot to answer for when it comes to harming the planet. While cars and trains are moving towards greener, electric power, emissions from air travel are expected to increase massively by 2050. If we want big green sky solutions, we need blue sky thinking Fortunately, there's plenty of that happening right now, particularly the short-haul flights powered by batteries.
Harbour Air is the largest seaplane airline in North America, flying 30, 000 commercial flights in 40 seaplanes each year. Significantly, all Harbour Air routes last less than 30 minutes, making it perfectly fit for electric engines. “As an airline, we're currently in the process of turning all our planes into electric airplanes. says CEO Greg Mc Dougall. To make this happen, the airline has partnered up with MagniX to create the worlds first commercial flight with an electric engine.
Making the skies electric isn't just good for the environment, it also makes sound financial sense: a small aircraft uses $400 on conventional fuel for a 100-mile flight, while an electric one costs $8-12 for the same distance, and that's before you factor in the higher maintenance costs of a traditional engine. There's also the added bonus that electric planes are just much more pleasant to fly in. No loud engine noise, no smell of fuel, just environmentally friendly peace and quiet.
While there has been real progress in the e-plane industry, the technical challenges that remain are keeping everyone's feet firmly on the ground. A battery, even a lithium one, only provides 250 watt-hours per kilogram; compare this to liquid fuel, which has a specific energy of 11, 890 watt-hours per kilogram. Carrying adequate batteries, however, would make the plane too heavy to get off the ground. In aircraft, where every bit of weight counts, this can't just be ignored.
The transition （过渡） from gas to electric in the automobile industry has been made easier by hybrids-vehicles powered by both fuel and electricity. Many believe the same pattern could be followed in the air. Fuel consumption could be reduced as the electric component is switched on at key parts of the journey, especially on take-off and landing.
It's certainly an exciting time for electric flying. With companies like Harbour Air taking the lead, battery-powered planes, especially on short-haul journeys, are set to become a reality in the next few years.

Nowadays, it is common in China that some people tend to run the red light in group when crossed the street. Actually, running the red light are quite dangerous. There are two main reasons which people run the red light. First, some people are in such the hurry that they ignore the traffic lights. Others took it for granted that drivers have to stop because so many people cross the street together. In order to prevent from this dangerous behavior, more overpasses(立交桥) should be built to make easier for the public to cross the street. Besides, people should be educate to follow the traffic rules and whoever breaks the traffic rules should be severe punished.
