How do you go to school every day? By bike or on foot? Maybe you can try a new way-taking a S’Cool Bus.

The S’Cool Bus is also called the bike bus. It was invented in the bike kingdom—the Netherlands. It is all about green lifestyle, sport and sharing. It’s interesting for kids to ride the bus together to go to school.

Also, it is very safe. The bike bus has a driver and eleven seats for kids. Each one has a helmet(头盔) and safety belt(安全带). There is also a roof on the bus. It can be used on hot days or rainy days to make kids feel comfortable.

Do you know how people in Zhuhai travel around the city? There are many ways, by bus, taxi, car, tram (有轨电车) or shared bike.

The most popular way is to travel by bus. It costs only one yuan and it’s free for old people over 60. Another way is to drive cars. Many people like to go out in their own cars because it’s very convenient and that’s why the traffic is so heavy. People can also travel by taxi. You can call a taxi on the cell phone. Usually buses, cars and taxis have to wait for the traffic lights for a long time. If you don’t want to wait for too long, you can take the tram or ride a shared bike. You can find shared bikes everywhere. It doesn’t cost too much and it’s good for health as well.

During the morning and afternoon, there is a “rush hour (车流高峰)” when people go to work or go back home from work. The best time to travel is from 9 a.m. to 4 p.m. Traffic is not so busy during this time because most people are already at school or at work.

Most people ride the bus to get from point A to point B, but riders taking a new route in Hong Kong are only interested in sleeping. Ulu Travel Agency, a tour company in Hong Kong, has designed a five-hour bus journey especially for passengers to sleep as much as they want. Tickets for the first tour on Oct. 16 sold out right away, The Washington Post reported.

Many people find it easy. But why? According to a website, there are several possible reasons.

White noise

White noise is a kind of noise made by sounds with different frequencies(频率) together. Buses are often crowded every day with people going to and from work. Therefore, they are the perfect environment for white noise. They make continuing noises. White noise makes people feel relaxed and helps them sleep.

Rocking movement

Another popular view on why it’s easy to fall asleep on buses is because of the rocking movement. “The movement of buses feels like a mother shaking a baby in her arms. It is very comfortable,” Frankie Chow, the founder of Ulu Travel Agency, told The Washington Post.

When you were a baby, you were rocked to sleep. That makes you connect the rocking movement with sleeping. Sitting on a bus gives people similar experiences. That’s why you want to sleep. It’s the rocking movement that induces sleep.

Long periods of inactivity

On buses, you don’t move around very much. You just sit down and enjoy the scenery as the bus moves along the road. Basically, you’re away from the things that keep your mind and your physical body busy. This inactivity also slows your brain activity down because there’s no stimulus(刺激物) to keep it awake.

Increase in carbon dioxide

Buses often get crowded with people going to and from work. Carbon dioxide (二氧化碳) increases when there are lots of people in a small place. The thinner oxygen(氧气) slows the brain down, causing people to feel sleepy.
