阅读理解。 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 ______. A. several meanings B. one meaning C. few meanings D. no meaning 2. A good dictionary will tell you _____. A. more of word's pronunciation B. more of the word's meanings C. more of grammar D. more of the word's spelling. 3. Phonetic alphabets are used to show ______.
