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.

"Do they understand that parents are fighting for our lives, our jobs, and our companies as well?" another parent said. "I' m a working mum. If I don't do my job, I may l4. it. I know things had to be done in a hurry. But parents have been thrown in the deep end.

Yvette McDonald, from the inner west, has two young children at a public primary school, which issues (发布) written lessons and requires typed, o5. communication, such as being present for roll call (点名) at the b6. and the end of each day. She has asked the NSW Department of Education to relax those rules, saying they were difficult to carry out.

"Parents are already at breaking point and we haven't even gone into formal lockdown, "she said. "Many of us are managing crisis at work, but then on top of that we're schooling our children as well. We feel as though we're failing, but we're not failing-we've been a7. to do very difficult things. We want to know what's essential and what's not."

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.

Most high school kids go from one class to the next, never getting a break from the books. What if kids had a chance to run a school radio station? Nathan Hill High School has a modern radio class that gives its students that very chance.

The students play the hottest music, produce ads and run testimonials. KNHC is known for playing up-and-down dance hits before any other station in the nation. KNHC-FM has 60, 000 listeners a week. Tim Green, the 18-year-old music director for KNHC, says, “For me, radio is a break from the usual school day. It is something I enjoy.”

Running a radio station is not all play. There is real work to do. The radio station stays on an exact timetable called an hour clock. The hour clock shows the time at which music and different announcements will be aired. The 17-year-old programme director, Shirley Smith, says, “All of that material airs within one minute, give or take, of the time that it’s written.”

Like any other job, hosting a radio programme should have special lingo, or language, for the students to learn. Below is a list of radio lingo used at KNHC.
