Schools are now running remote (远程) lessons for more than 90 per cent of NSW students because of COVID-19 (冠状病毒) crisis, a situation likely to l1. for months. The NSW Department of Education says the lessons are designed to be done without parents' too much caring.

But parents are still under the pressure of trying to support their students' learning, saying they have been given an i2. task.

One parent said she spent the week working at her job, then the weekend catching up on all the work her children had missed, doing housework at night. Another single mother wakes at 3 a.m. to do her paid work so she can supervise (监督) her children d3. the day.

In the eyes of many foreigners, Chinese are the best hosts and the worst guests in the world. And western hosts sometimes look impolite in the eyes of Chinese guests. It’s because the guest- host relationship in China is quite different from that in some western countries.

In China, guests are almost like gods. Whenever I enter a Chinese friend’s home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the west, generally the guest is not a god. Acting according to the host’s way of doing things is usual behavior for a guest.

My wife’s mother, a very kind Chinese lady, doesn’t smoke. When I see her guests smoking in her house, as a non-smoker, I feel unhappy. Usually, I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North American homes, if you are a guest, and the hosts are not smokers, you should ask, “Is it OK if I smoke?” But don’t be surprised if they say, “No.” In my culture, if you smoke in their house, you are a bad guest, but if they don't allow you to smoke in their house, they are not impolite hosts.

Guests in China also have special habits. They usually give hosts gifts when visiting a Chinese family. However, it’s not necessary in my country. So if you invite foreign guests to your home, don’t be too surprised if they don’t bring you a gift.

In a word, no matter where you are, the best way to be a good guest is to adapt (适应) to the habits of your hosts.

1.When a western guest visits a Chinese family, he is often regarded as a god.

2.The writer’s wife’s mother will stop her guests smoking because she isn’t a smoker.

3.According to the article, the writer is probably a Chinese.

4.It’s necessary for a guest to give the host a gift when visiting a western family.

5.The writer tells us to act as the host does when visiting someone’s home.

Our smart phones are amazing, but our connections can be so slow. The future in science-fiction movies seems so close, yet so far away. 5G technology makes that future look easily achievable. What is 5G? It’s the latest generation of cellular (蜂窝状的) network technology. It is faster and more stable (稳定的) than 4G. This powerful wireless network will change the way we live.

Transportation

With the introduction of 5G and smart technology, traffic lights, buses and even cars begin to communicate with each other. We will be able to check traffic flow so that traffic jams (拥堵) may soon become a thing of the past. Moreover, it’s reported there is a good possibility of seeing driverless cars on our roads. With the help of 5G, these cars will be able to react to sudden changes in their environment at once, such as a dog running across the road.

Medical treatment

With 5G networking, all the people can have the chance to use top medical resources. Before treatment, 5G will support video calls with doctors and provide advice for those who can’t visit a hospital at once. After being treated, wearable tech will send information to doctors in no time, allowing hospitals to monitor the patients from their homes. It also allows surgeons to perform operations remotely, using robots. In March, 2019, China completed its first 5G-based human brain surgery between a doctor and a patient located more than 4,000 kilometers away. Five months later, robots guided by Beijing doctors completed a test operation in three different locations at the same time!

It seems that 5G will make our life more exciting and convenient wherever we use it.
