Flying is a fast way to travel. But it is a big headache for some people. They can’t help worrying about things like “Is it dangerous if we don’t change our mobile phones to airplane mode (飞行模式)?” Here are some interesting facts about flying.
Why are plane windows round?
It’s for safety. As the airplane flies higher and higher, the atmospheric pressure (气压) outside gets lower and lower. During the flight, the pressure inside the plane becomes greater than the pressure outside. When this happens, square windows can break. That’s because having different pressures inside and outside puts stress on the corners of square windows. But rounded corners can spread the pressure more evenly (均匀地) across the window’s surface, making it less likely to break.
What happens when a phone isn’t in airplane mode?
Some passengers believe mobile phones and tablets(平板电脑) need to be turned off because they can bring the plane down. However, this is not true. If you don’t change your phone to airplane mode, pilots and air traffic controllers may hear unpleasant sounds in their headphones. This makes it harder for them to communicate. So it’s still best to put your devices (设备) in airplane mode.

To prevent the spread of the novel coronavirus, governments at every level in China have been using many different control measures.
In heavily-affected areas, the government has chosen to lock down cities. In Hubei province, for example, after Wuhan’s lockdown on Jan 23, thirteen other cities in the province also taken lockdown measures. The decision proved effective (有效的) in stopping the virus’ spread at its root, China Daily said.
In some villages, people put up red banners (条幅) or used loudspeakers to educate people about the virus. Many communities also set up checkpoints to check people’s temperatures, keep records of their travel history, keep non-residents (非住户) out of the community, and make sure that people quarantine (隔离) themselves after returning from high-risk areas. Some community workers also help those who stay at home by bringing in food or medicine, taking out the rubbish, and offering psychological (心理的) advice. The community workers have built the first line of defense (防御) against the virus across China.
According to Xinhua, there are millions of community workers in 650,000 urban and rural (城市和农村)communities across the country. Many people from all walks of life have volunteered to do this job.
“In the face of an unexpected outbreak, it’s amazing to see that China could organize people on such a large scale (规模),” Li Baoping from the Ningxia Academy of Social Sciences told Xinhua. “Great governance capacity (治理能力) at all levels gives us confidence in winning the battle.”
