表语是什么意思-尊龙官方网站
表语是用来说明主语的身份、特征和状态的,它常位于联系动词(be, become, appear, seem等)之后。所以要判断一个结构是不是表语,我们只要看这个结构前面的动词是不是系动词。
表语是什么意思
表语是说明主语的身份、性质、品性、特征和状态的,表语位于系动词之后,与系动词联系十分紧密,有系动词就有表语,有表语就有系动词。通常由名词、形容词、副词、介词短语、不定式、动名词、从句来充当。如果句子的表语也是由一个句子充当的,那么这个充当表语的句子就叫做表语从句,表语就是起表述作用的句子成分。
例如:
i amfine. ( fine 是形容词,作表语)
he is aboy. ( boy 是名词,作表语)
five plus two isseven. ( seven 是数词,作表语)
we arehere. ( here 是副词,作表语)
he is notat home. (at home 是介词短语,作表语)
my hobby isreading. ( reading 是动名词,作表语)
our duty isto make our environment better.(to make 是不定式,作表语)
