When someone does something for us or gives us something, saying “Thank you ”is good manners. When we want others to pay attention to us, it’s good to say “excuse me”. However, good manners are more than words. Good manners are also actions.
When we give someone else our seats on a crowded bus, when we hold the door open for another person to walk through, and when we knock before opening the door of a room, we show our good manners. When we meet someone for the first time, it’s good manners to smile and say “hello” and give our name.
Sometimes, good manners can be the things we don’t do. For example, when we don’t talk with a full mouth or cut in line, that is showing good manners.
People often feel “not quite right”. Bad weather, a busy day, and health problems can make people sad. If we use good manners, we make getting along easier for everyone.

Body image (身体形象) — the way people feel about their looks — is a big problem for many people today.
But what’s the cause? In the study, many people point at the media (媒体). Turn on the TV, or look through the Internet and you’ll probably see beautiful models, handsome actors and healthy and strong sports stars.
Many young people feel stressed to look like these “perfect” people. According to a study, more than half the teenage girls in the USA think they should be on a diet. And almost 20% teenage boys are worried about their bodies and weight.
Body image problems don’t disappear as we get older, either. In the UK, for example (化妆品) than any other age group. Older men are having less and less hair, so they also spend a lot of money.
Is there a solution to this problem? A study in the UK advised that body image lessons should be provided in schools. Others suggest we need to judge (判断) people by what they do, not what they look like.

【推荐3】May 12th, 2018 is the 10th anniversary (纪念日) of Wenchuan Earthquake. The earthquake caused a huge loss to people. It has been worried widely about what we can do when we meet accidents. Therefore, how to deal with accidents in our daily life?
Earthquake is the first thing that I want to talk about. Firstly, you need to rush to open space quickly if you are on a lower floor. Meanwhile, you should avoid trees or wires (电线) around you. You need to stay in a corner which seems hard enough if you are in a higher building. Do not be a jumper! You should keep your body safe and wait for others to help you.
When it comes to fire, you need to know the direction of the fire and find out security exits. The best way is to cover your nose and mouth with a wet towel. Then you should stay close to the floor and move quickly. Do not use elevators.
Another accident is drowning (溺水). Every summer, about 5, 000 kids die because of swimming alone in the river or the lake. Experts say that we might drown if we struggle (挣扎) as possible as we can. Because it would make the water flow more quickly. So what we should do is “To take a deep breath, lie on the water and wait for others to save us.”
In a word, all kinds of accidents will happen in our daily life. The most necessary thing is to keep calm and find the exact way. We should believe we can not only get a chance to save ourselves but also help others if we learn about how to deal with them in the first place.

The documentary also shows us the world’s largest maritime drilling rig Blue Whale 2, and the development of 5G mobile technology.
Amazing China also records the stories of normal people, such as engineers who do building work, grass-roots officials who help poor people become rich, and workers who try to make use of new technology in their factories.

【推荐3】What is 5G? It is the fifth generation(代)of mobile network technology. These new networks are coming.
China gave out commercial license(商用牌照)for 5G on June 6, 2019. This means that China’s Telecom(中国电信)companies have been 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(数据)and the Internet. And 4G made all of these things faster. What’s special about 5G?
5G has a very short delay(延时)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. This big change will not only make our mobile Internet faster, but also deeply change our lives.
5G + entertainment(娱乐)
5G networks are about 100 times faster than 4G. This means you can download(下载)a movie in seconds.
5G + transportation
5G will also bring us safer self-driving cars. These cars can send signals(信号)to each other. 5G will allow cars to react(反应)even faster than real 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, if its sensor(感应器)feels the air becoming dry, a smart sprinkler(喷壶)can water your plants by itself.
