Teaching English to your family members is a great way to improve your own English. Learning something new together can make you closer to your family members, too.

Here is some advice for you:

Film night: choose an English film with Chinese subtitles字幕. You can stop the film at any time and help your family learn new words and expressions according to subtitles on the screen.

Sports night: you can invite your family members to go skating or swimming. You can teach a few words when you play sports together. For example, “you fell down” or “your skates look cool”.

Novel night: choose a classical English story that your family members may know. You can read it to your family members and tell them about the novel in English

Make an English family tree together: you can teach your family members what each person is called in English, such as “father” and “cousin”. It is a good way to make your family members interested in English.
