Dear Xiaohua，
Glad to receive your letter. You asked me how to use a dictionary to learn English. Here are some of my thoughts.
Words in a dictionary are called entries. Each entry has five sections， such as pronunciation， part of speech， definition， usage and word group. Of course， sometimes the same word has different parts of speech and definitions.
Using dictionaries can solve problems in vocabulary learning. When we meet a new word， with the help of a dictionary， we can not only find out its pronunciation， but also know its meaning. A dictionary is of great benefit to English learning. First of all， it can help us understand the meaning of words accurately. Secondly， it can enrich our knowledge and exercise our thinking. Finally， it can help us learn to express our ideas.
I hope it's helpful to you.
Yours
Ann
