Have you ever learned to do something with the help of an Internet search? The answer is likely "Yes"! In fact, you probably learned many things by watching how-to videos.

You may be wondering how such videos can improve your English. Recording yourself, whether on video or audio (音频), is an effective method of self-study. This is especially true if you cannot find someone to practice speaking with. When you record yourself, it helps you identify what you are good at in English and which areas need improvement. As you continue the method of speaking on a recording, you can make the changes you want.

Now, let's go through the steps in preparing to make your video.

Choose a subject

The first step is to choose a subject that will work well for a short video. Set a goal of not going over six or seven minutes for the video length.

Gather information

Make a list of the steps that you think are important in making or doing the thing you have chosen. You might not know the English words for some of the things you are describing. For those, you can write the words in your own language and then take time to find and practice saying them in English.

Aim for simple instructions

How-to videos are meant to make instructions easy and clear. Taking notes can help organize your steps and decide which to include. Think about which ones to show visually and which ones to be described.

Introduce your subject

A great way to introduce it is to say your name and then say what you are going to show. You can even include a sentence or two about why your skill is good to learn.

If you look at the top of your phone, you'll usually see a small symbol that shows 3G or 4G. The "G" means the "generation(代)" of your mobile network. But they will become history after 5G network fully arrives.

In recent years, China makes great achievement in 5G network. Now it's making efforts to popularize the business use of 5G. Shanghai is the first city in China to start testing 5G networks. On March 30, 2019, Wu Qing, one of the leaders of Shanghai, made the first 5G video call with Huawei Mate Smartphone.

5G allows people download and upload data faster than ever before. It is 100 times faster than 4G mobile network. But 5G doesn't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G can make self-driving cars safer.

Today's self-driving cars have one problem—time lag(滞后). When a self-driving car "sees" an obstacle(障碍物), it sends this information to data center and receives instructions. However, it takes time to do that. That's the time lag. With this kind of lag, the car might have an accident because it doesn't receive instructions in time. But with 5G, the self-driving car can receive instructions more quickly.

5G can also be used to power the Internet of Things (IoT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IoT, your smart fridge could order eggs online when it notices that there are no eggs left inside.
