一般说来 ,英语谓语可以分为三类 :简单谓语、复合谓语和双谓语。双谓语结构为“实意动词 +后续成分” ,其中 ,实意动词可以是持续性的 ,也可以是非持续性的 ,但大多数情况下不及物 ;可充当其后续成分的有形容词、过去分词、现在分词、名词、介词短语及从句。双谓语并不等于“复合谓语” ,可以用“删除法”和“替代法”来加以区别。双谓语与外位成分有些相似 ,但它们无论在结构、构成还是功能方面都有差别。本文还探讨了谓语的后续成分与状语的区别。 In general, English predicates can be divided into three categories: simple predicate, compound predicate and dual predicate. The dual predicate structure is “intentional verb + follow-up component”, in which the intentional verb can be persistent or non-persistent, but in most cases less transitive; the adjective, past participle, Now participles, nouns, prepositional phrases and clauses. Dual predicate does not mean “compound predicate”, you can use the “Delete Law” and “Alternative Law” to be distinguished. Dual predicates are somewhat similar to extrinsic ones, but they differ in structure, composition, or function. This article also explores the difference between the following components of predicate and adverbials.
