阅读理解。 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.
