The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context（上下文）.Then they reread and use the dictionary to look up only key words that they do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables （音節(jié)）, they always use a dictionary. Also, if they think a noun might have an unusual plural form or a verb might have an unusual past form, they cheek these in dictionary.
