Dear David,

     I've been feeling very bad these days because I failed another English test. I tried my best, but I still

couldn't get good grades. It's hard for me to memorize English words and I have a lot of difficulties with

the grammar. Since I am a little shy, I am afraid of speaking English in class. I know studying English well

is very important, so I don't want to stop studying it. How do you study English? Can you give me some

advice?

                                                                                                              Yours,

                                                                                                                    Tom 

Dear Tom,

     I'm glad to help you. As for how to study English, here is my advice.
