Nowadays everybody seems to think that they know English. Many people speak it but few speak it really well. Practice is necessary in speaking English well.

Reading is also one of the things that will help you to speak English better. Read whenever you can and whatever you like! Read papers and Internet sites that you like in English every day. Then, you will see that the number of known words is increasing and you are able to speak with more skills. Then you will have made the foundations(基础)and a good basis of English.

Going to England or an English speaking country is a good choice, but many people cannot afford it. If you cannot go, reading and speaking with your friends will also help you to practice your English.

Nothing can match the excitement and happiness when a native speaker tells you that your English is very good!
