根據(jù)其是否能用作謂語,動詞可分為謂語動詞和非謂語動詞。謂語動詞在句中可用作謂語,而非謂語動詞則不用作謂語(但可用作主語、賓語、補語、狀語、定語等)。非謂語動詞包括不定式、動名詞、分詞三種:
He lives in Shanghai. 他住在上海。(live 為謂語動詞)
I want to go home. 我想回家。(want 為謂語動詞,to go 為非謂語動詞)
He enjoyed watching TV. 他喜歡看電視。(enjoy為謂語動詞,watching為非謂語動詞)
He had his hair cut. 他理發(fā)了。(had 為謂語動詞,cut 為非謂語動詞)
