     Most dictionaries will tell you a number of things about a language. There are three important things.

These three things are spelling, pronunciation and meaning.

     First, a dictionary will tell you the spelling of a word. If you are not sure about the spelling of a word,

you can try to find the correct spelling in a dictionary. Words are listed in an alphabetical order-a, b, c and

so on. For example, on a dictionary page the "poor" comes before "poverty" and the word "poverty" comes

before the "power". The words are always given in alphabetical order. The second thing, a dictionary will

tell you the pronunciation. Most dictionaries give phonetic (语音的), or sound alphabet. The phonetic

alphabet shows pronunciation. The third thing, a dictionary will tell you the meaning of words. You can

look up a word and find out what it means. Many words have more than one meaning, and a good dictionary

will tell you all of the word's meanings. For example, in English the common word "get" has over 20 different

meanings.

1. Many words have ______.
