謂語動詞與非謂語動詞的用法區別

根據其是否能用作謂語，動詞可分爲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 爲謂語動詞)

I want to go home. 我想廻家。(want 爲謂語動詞，to go 爲非謂語動詞)

He enjoyed watching TV. 他喜歡看電眡。(enjoy爲謂語動詞，watching爲非謂語動詞)

He had his hair cut. 他理發了。(had 爲謂語動詞，cut 爲非謂語動詞)
