短语类型 构成与作用 示例
名词短语 (Noun Phrases) 由“限定词＋（形容词等）＋名词（＋介词短语/不定式等）”构成，在句中作主语、宾语、表语等。 a difficult challenge；the young man at the door；something useful to read

副词短语 (Adverb Phrases) 以副词为中心，常由程度副词修饰，在句中作状语，修饰动词、形容词或整个句子。 speak English quite fluently；finish the work on time；very obviously
判断方法：先找中心词——中心词是名词则为名词短语，是形容词则为形容词短语，是副词则为副词短语；再分析整个短语在句中所作成分。
