1 . Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.
What is 5G? What difference will it really make to our lives? The “G” in “5G” refers to the generations of mobile network technologies.
1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.
5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G.The short delay of 5G will make the games feel even more real.
Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.

2 . Eden Gross wants kids to know that they’re not alone when they feel afraid. “I get fearful sometimes,” said the Florida fourth-grader, who has often been drawn to dark stories. At age 8, Eden started writing songs to deal with her fears. Last month, she released (发行) her first song, “Shadows on the Wall.” It’s for kids everywhere who have problems with mental (精神的) health. The point of the song is that the fears “aren’t reality,” said Eden, now 10. “I am bigger than these fears.”
Eden began writing “Shadows on the Wall” in 2019 after attending the Throga Retreat, a youth singing program about two hours from her home in Parkland. There, she met Johnny Cummings, a New York-based singer, songwriter, and producer. After the program, the pair worked together each week through Skype. They finished “Shadows on the Wall” and a second song, “The Last Kid on Earth,” which centers on the idea that although each person is different, we all feel alone sometimes.
Eden wants more grown-ups to understand the influence of COVID-19 on children. “They’re used to running around, playing with their friends. Getting used to new realities was really hard,” Eden said.
Eden and her twin brother, Jordan, recently marked one year of distance learning (远程学习). It was unusual at first. They weren’t getting used to it and missed their days in school. “The Internet has become our whole world,” said Eden. “Technology has become our new way of connecting.”
One lesson from COVID-19, said Eden, is to “find a way to do what you love and be who you are, no matter the environment.” For Eden, that means spending time with the family’s pet, Ollie, and continuing to follow her dream of music and writing. She’s busy with her third song, “The Voices.” “It’s about judging (评价) yourself in your head when you say, ‘I’m not good enough,’” she said. “And then realizing, ‘I am good enough. I am good enough for me.’ ”

It is no doubt that we produce lots of garbage every day. However, few people have the habit of sorting waste.
This will bring lots of problem. First, the value of things that can be recycled or reused, such as plastic and paper, are reduced. Besides, deal with some waste by burning it will cause serious environmentally pollution.
For those reasons, the government should taken effective measures to call for waste sorting. More publicity campaigns and public service advertisements should run to raise public aware. The government can also design the colorful garbage cans with clear waste-sorting images on it to encourage people to sort waste.

7 . Online education has grown fast over the past ten years. The explosion of technology has made teaching outside the traditional classroom possible for teachers and has provided learners with easy access to course materials. Its attractiveness, benefits, and challenges are addressed.
In April, 2005, I was approached by a student who was interested in our doctoral program. However, the first question out of her mouth was, “Do you offer any online courses?” Later that day, as I was reading the conference program guide trying for interesting presentations, I noticed many workshops on web-based learning and online education. I later attended two of those workshops and met several professors from different universities who had either taught online courses for quite some time or who were discovering the best practice for teaching online. These experiences helped me realize at least to some extent the degree of growth in online education.
My responsibilities for the term included gaining more understanding of online education. Consequently, I made several attempts to enrich my knowledge of distance learning and online teaching. I consulted with my colleagues who were teaching online courses. This helped me recognize the importance of getting materials prepared even before the start of a term. I also learned that online courses may consume more time than regular classroom teaching. And I attended several workshops regarding online education and established a network with those who were involved in online programs at other universities. I will consider these people as my consultants as I begin to design my own online course. Also, I conducted a brief survey with 15 students and two faculty members who had taken or taught an online course before to understand their experience. Eventually I completed a literature review which gave me the foundation and the background of understanding the need for online education.
