Siri not only understands what you say,but it's also smart enough to know what you mean. So when you ask, u Any fast food restaurants around here?"

English is an important subject in a middle school. Almost everyone knows that we should learn English well,but few know how to learn it well. Karl Marx once said, " When someone is learning a foreign language, he must use the foreign language. " In this way, he learned several languages. Here are some suggestions on how to learn English.

First, use all your senses to learn English. You must hear English,read English,touch English,smell English, and taste English. Feel English with your heart and leave yourself in this language. That means we should read more, speak more,listen to English and practice writing every day.

Second,keep a small English dictionary with you at all time. When you see a new word, look it up. Remember and use it in your mind or in a sentence.

Third, try to think in English as often as possible. When you see something, think of the English word of it,and then think about the word in a sentence.

Fourth,keep writing an English diary every day. Try to write some sentences about your day and then blurt(脱口而出)them out as many times as possible before you go to sleep.

Last,don't be afraid of making mistakes. Relax!  Remember that learning any language takes a lot of efforts, but never give up.
