    Speaking is different among the four skills in learning English. The other three you can do alone on your

own,but you can't really speak alone. Speaking to yourself can be "dangerous" because men in white coats

may come and take you away! Then how can you practice speaking? Where can you find people to speak

English with?

    At school-If you pay to go to a language school, you should use the chance to speak. If your teacher asks

you to speak in pairs with other students, try to say as much as possible. Don't worry about your mistakes.

Just speak!

    Cafes and bars-There are American,British,Irish and Australian bars in many big cities. If you can find

one, you will probably meet many people speaking English as their first or second language.

    Songs and videos-Repeat the words of an English song singing with the music until it becomes automatic

(不假思索). It's good practice for your memory and for the mouth muscles (肌肉) that you need for English.

    Language is all around you-Everywhere you go, you will find language. Shop names, notices, and car

numbers…When you walk down the street, practice reading the words and numbers that you see. Say them

to yourself. It's not exactly a conversation, but it will help you to "think" in English.
