非谓语和谓语有什么区别?非谓语作状语?
谓语:谓语主要充当主句的谓语,主要由动词及相关动词短语、词组等充当,有时态和数的变化,需根据句子相应句意、句子结构等而确定,为主语发出的动作。是主句句子结构不可缺少的一部分。
如:
(1). She likes singing.
(谓语:likes,由主语“she”所发出的动作,且 she 为第三人称单数,谓语也应体现单数。)
(2). I went to play basketball with my friends yesterday.
(由时间状语 yesterday 得知,动作发生于过去,谓语动词 go 应体现过去时态,所以应变为过去式 went)
非谓语动词:句中已存在谓语动词,在句中出现的该动词只能在句中充当非谓语成分,常由现在分词、过去分词等充当,非谓语在句中可作状语、定语等作为修饰补充说明,使句子结构、句意更为完整。
如:
(1). The book bought by my father has been brrowed by my friends.
(bought by my father 作为句中定语定语修饰名词 book)
(2). My father got home giving me a book this afternoon.
(giving 是由主语“my father”所发出的动作,应用现在分词“giving”,且作为句中的伴随状语)
