▶DefinitinsFunctin wrds are used t create a structure int which the cntent wrds will fit and shw the relatinships between them. These are “small” wrds, such as prnuns, prepsitins, and cnjunctins. Cntent wrds are nuns, verbs, adjectives, and adverbs which give a sentence meaning. ▶Differences实义词传递文本内容中的重要信息，一般需要重读，但并不是句子中所有的实义词都需要重读，而需要视语境和说话者的交际目的而定；功能词表达的是词与词之间、句与句之间的关系，是用来把文本中的重要信息连接起来，不用重读。
