You should know that this habit is bad for your hearing. Over 1 billion young people are at risk of hearing loss （聽力喪失） ,because of listening to loud noise for long periods of time. Listening to music or watching a TV show at loud volumes can harm your hearing. The United Nations has standards for safe listening. It is not safe to listen to sounds that are louder than 85 dB （分貝） for eight hours or 100 dB for 15 minutes. The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB. Loud noise is harmful to the inner二Most of us are bon with about 16,000 hair cells （聽毛細(xì)胞） in our inner ears. These cells notice sounds. However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die. This is what causes hearing loss. Once this happens, it39。s hard to get your hearing back. Some people might think that their music isn39。t all that loud. But this can depend on where you are. For example, if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. Later, when you listen to it at the same volume in a quiet place, you alight feel unfortable The safe level for most sound is below 80 dB for up to 40 hours a week. A level of 80 dB is about equal to （相當(dāng)于） the noise of a subway. Here is some advice on safe listening. Over—the—ear headphones （頭戴式耳機） are better than in—ear ones. They do a better job of stopping outside noise, so you can listen at a lower volume. Don39。t listen to loud music on your headphones for a long time.

The G stands for the generation （代） of your mobile network. But the symbols will bee things of the past after 5G networks fully arrive. On March 30, Shanghai vicemayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also bee the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data（數(shù)據(jù)） faster than ever before. But 5G won39。t just bring faster mobile internet. People can use it for many other things as well. For example, 5G will help to make selfdriving cars safer. Today39。s selfdriving test cars have one problemlag（延遲）. When the car sees an obstacle（障礙物）, it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don39。t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.5G could also be used to power the internet of things （IoT）, that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically （自動地） place an order online for eggs when it finds that there are no eggs left inside.（1）Which city was 5G tested for the first time?
