课堂探究
在高中阶段,常见的短语形式有:名词短语(Noun Phrase)、形容词短语(Adjective Phrase)、副词短语(Adverb Phrase)、介词短语(Preposition Phrase)及动词短语(Verb Phrase)等。本单元只讲解前三种形式。
探究点1:名词短语(Noun Phrase或NP)
名词短语, 指以一个名词为中心构成的短语,在句中的功能相当于名词,可作主语、宾语、表语或宾语补足语。常见名词短语的构成形式有:
(1)限定词+名词,如the girl; my bag
(2)限定词+形容词(短语)+名词,如a beautiful girl; his new jacket
(3)限定词+形容词+名词+介词短语,如a beautiful campus of my school
(4)限定词+描述性名词+名词,如my school life
1.限定词包括冠词(a/an/the)、指示代词(this/that/these/those等)、物主代词(my/your/his/her/our/their等)、不定代词(some/no/neither/both等)和数词(one/two/first/second等)。
2.多个形容词修饰名词时,其顺序为: 限定词——数词——描绘词——出处——材料性质——类别——名词。
如:a small round table/a tall gray building/a dirty old brown shirt/a famous German medical school/an expensive Japanese sports car
①There are some red roses on the small table.
在那张小桌上有一些红玫瑰。
(名词短语some red roses的构成形式为:限定词+形容词+名词,在句中作主语;另外, the small table也是名词短语,在句中作介词on的宾语)
②I have three close friends.
我有三个要好的朋友。
(名词短语three close friends的构成形式为:限定词+形容词+名词,在句中作have的宾语)
③He is my best friend.
他是我最好的朋友。
(名词短语my best friend的构成形式为:限定词+形容词+名词,在句中作is的表语)
