How can you improve English listening? Here are two ways. I(希望) they can help you.

It's(必要的) to listen to the English radio. You should try to listen to the radio for at(最少)20 minutes every day. Do it on the bus, on your way to school, or when you travel. It's (常见的) that you have difficulties. Try to pick out key (信息) to get a general （总的）idea of what it is about.

    The other way is to watch English movies and TV shows. If possible,(选择) movies or shows that you know about, such as children's (动画片) or famous films. If you already know the (主要的) story, you will find the language much easier to pick up. (然而)， you should not watch movies or shows (有) subtitles (字幕) in your first language, or you'll not focus on understanding the English.
