When I first entered university, my aunt, who id an English professor, gave me a new English dictionary. I was    36   to see that it was an English-English dictionary, also known as a monolingual dictionary.   37   it was a dictionary intended for non-native learners, none of my classmates had one    38   , to be honest, I found it extremely   39    to use at first. I would look up words in the dictionary and    40   not fully understand the meanings. I was used to the    41   bilingual dictionaries, in which the word are    42   both in English and Chinese. I really wondered why my aunt    43   to make things so difficult for me. Now, after studying English at university for three years, I    44  that monolingual dictionaries are    45   in learning a foreign language.

As I found out, there is,   46   , often no perfect equivalence(对应)between two    47   in two languages. My aunt even goes so far as to    48   that a Chinese “equivalent” can never give you the    49    meaning of a word in English!   50   , she insisted that I read the definition(定义)of a word in a monolingual dictionary   51   I wanted to get a better understanding of its meaning.    52   , I have come to see what she meant.

Using a monolingual dictionary for learners has helped me in another important way. This dictionary uses a(n)   53   number of words, around 2,000, in its definitions. When I read these definitions, I am    54   exposed to(接触)the basic words and learn how they are used to explain objects and ideas.    55   this, I can express myself more easily in English.
