When I first entered university, my aunt, who is an English professor, gave me a new English dictionary. I was    1to see that it was an English-English dictionary, also known as a monolingual dictionary.    2it was a dictionary intended for non-native learners, none of my classmates had one.    3, to be honest, I found it extremely    4to use at first. I would look up words in the dictionary and    5

not fully understand the meanings. I was used to the    6bilingual dictionaries, in which the words are    7both in English and Chinese. I really wondered why my aunt    8to make things so difficult for me. Now, after studying English at university for three years, I    9that monolingual dictionaries are    10in learning a foreign language.

As I found out, there is,    11, often no perfect equivalence(对应)between two    12in two languages. My aunt even goes so far as to    13that a Chinese “equivalent” can never give you the    14meaning of a word in English!    15, she insisted that I read the definition(定义)of a word in a monolingual dictionary    16I wanted to get a better understanding of its meaning.    17, I have come to see what she meant.

Using a monolingual dictionary for learners has helped me in another important way. This dictionary uses only a(n)   18number of words, around 2,000, in its definitions. When I read these definitions, I am    19exposed to(接触)the basic words and learn how they are used to explain objects and ideas.    20this, I can express myself more easily in English.
