What constitutes our word knowledge？
【正确答案】：First, the pronunciation of words is part of our word knowledge. We need to have an accurate representation of the pronunciation of words in the first place in order to have easy access to them in oral language comprehension and production.
Secondly, syntactic knowledge is another part of our word knowledge. We need to know the syntactic category to which a word belongs and include syntactic categories in the lexical entries in our mental dictionary.
The third type is morphological knowledge. We should know what morphemes (free or bound) are combined to form new words or grammatical forms.
Finally, we should have knowledge of the meanings of words. Sense, reference, sense relations, denotation and connotation should all be included in the entries in our internal lexicon.
