句子成分
1. 表语:表语用以说明主语的身份、特征和状态,它一般位于系动词(如be, e, get, look, grow, turn, seem等)之后。表语一般由名词、代词、形容词、分词、数词、不定式、动名词、介词短语、副词及表语从句表示。
例:Our teacher of English is an American.(名词)

2. 宾语补足语:英语中有些及物动词,除有一个直接宾语以外,还要有一个宾语补语,才能使句子的意义完整。带有宾语补足语的一般句型为:某些及物动词(如make等+宾语+宾补)。宾补可由名词、形容词、副词、不定式、分词、介词短语和从句充当。
例:
His father named him Dongming.(名词)
They painted their boat white.(形容词)
Let the fresh air in.(副词)
