In English grammar, a phrase is a group of two or more words functioning as a meaningful unit within a sentence or clause. A phrase is commonly characterized as a grammatical unit at a level between a word and a clause. A phrase is made up of a head (or headword)—which determines the grammatical nature of the unit—and one or more optional modifiers. Phrases may contain other phrases inside them. 短语的定义 短语是具有一定意义但不构成句子或从句的一组词。可分为Noun Phrase名词短语、Adjective Phrase形容词短语和 Adverb Phrase副词短语。 Phrases（短语或词组） 1.名词短语 (NP)：指以一个名词为中心构成的短语 eg: a beautiful girl 2. 形容词短语 (AdjP)：指以一个形容词为中心构成的短语 eg: a little confusing 3. 副词短语 (AdvP)：指以一个副词为中心构成的短语 eg: quite quickly （1） 名词短语 (Noun Phrase)：是以名词为中心的短语，在句子中的作用相当于一个名词，在句中作主语、宾语、表语等。名词的修饰语与名词有两种位置关系：一是放在被修饰名词的前面，作前置定语；二是放在被修饰名词的后面，作后置定语。 名词短语（Noun Phrase）的构成 ① adj. + n. /n. + adj. extra-curricular activities 课外活动 homeless people 无家可归的人 advanced maths 高等数学 people present at the meeting 出席会议的人们 ② n. + n. the school football team 校足球队 a woman doctor 一名女医生 ③ n. + and + n. teachers and students 老师和学生 ④ v.-ing + n. / n. + v.–ing a sitting room 起居室 the sleeping boy 正在睡觉的男孩 reading ability 阅读能力 students reading in the classroom 在教室读书的学生们 ⑤ -ed + n. /n. + -ed fallen leaves 落叶 photos taken by Mike 迈克拍的照片 ⑥ n. + to do the meeting to be held tomorrow 明天要召开的会议 ⑦ n. + 介词短语 a solution to the question 问题的解决办法 the main purpose of the course 该课程的主要目的 the safety of all the students 所有学生的安全 ⑧ 限定词 + n. an English book 一本英语书 my schedule 我的时间表 功能：在句中当作名词用，一般用作主语、宾语、表语或宾语补足语。 These interesting books are for you.(主语)这些有趣的书是给你买的。 He is my old friend.(表语)他是我的老朋友。 He had a big dinner.(
