The outbreak of new coronavirus first detected in China is serious. You may feel scary. Here are some simple ways that protect you from catching it.

Wear masks outdoors

Wearing masks is one of the most effective ways to protect you from getting infected.

Make sure to wear it properly by tightening up the nose clip and pulling the bottom of it so that your nose and mouth are both covered.

If you are not feeling well or have symptoms such as fever, fatigue, cough and trouble breathing, a mask is also needed to prevent you from spreading virus to others.

Surgical masks used by medical workers are not recommended for common people as they may lead to oxygen deficient if worn for long periods.

Cover your coughs and sneezes with tissue

Cover your mouth and nose with a tissue when you cough or sneeze, or you can cough or sneeze into your sleeves, but avoid covering with your hands directly.

Wash your hands frequently and properly

Wash your hands with soap and running water thoroughly for no less than 15 seconds. Wash your hands before eating and after using the toilet. Wash your hands after returning home. Wash your hands after touching trash or garbage. Wash your hands after contacting with animals or handling animal wastes.

Strengthen your immune system and exercise regularly

Exercising regularly is one of the most important ways to help you stay away from catching any infections.

Make sure that shared spaces have good air flow and avoid going to crowded places such as hospitals, the railway stations and airports. Wear a mask if transport or movement is necessary.

Avoid close contact with peoples who have flu or cold-like symptoms.

Eat thoroughly cooked meat and eggs. Avoid contact with wild animals or farmed livestock if there is not any protection.

Seek prompt medical attention if you have symptoms or respiratory infection.

China just issued commercial licenses (發(fā)放商用牌照) for 5G on June 6. This means that China's telecom companies were soon able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What's special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less—this is almost real-time.

This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.

5G+entertainment (娛樂)

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

5G+transportation

5G will also bring us safer self-driving cars. These cars can send signals (信號(hào))to each other. They also talk to traffic lights and road sensors (傳感器). 5G will allow cars to react even faster than human drivers.

5G+smart homes

5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

For example, your toaster can automatically (自動(dòng)地)start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
